Description
The present invention relates to a movable form for a tunnel lining device, and more particularly to a movable form for a tunnel lining device used when a concrete wall as a primary lining is formed on an inner peripheral wall surface of an excavated tunnel.
Generally, after a tunnel is excavated in a rock mass, a concrete wall is formed as a primary lining wall on an inner peripheral wall of the excavated tunnel. This prevents sand from falling from the inner peripheral wall surface of the tunnel, reinforces the inner peripheral wall surface of the tunnel, and improves the appearance. The primary lining wall is constructed by disposing facing formworks at a predetermined distance from the inner peripheral wall surface of the tunnel, pressing concrete into a space defined between the inner peripheral wall surface of the tunnel and the formworks, and removing the formworks after the concrete is hardened. In addition, a primary lining can be continuously constructed following the tunnel advance.
In order to facilitate understanding of the present invention, a conventional technique which is the basis of the present invention is described in detail with reference to fig. 1. This prior art is a prior invention in the name of the applicant of the present application and is disclosed in publication Sho 60-51299 (published as 2/22 in 1985).
As can be seen from fig. 1, a tunnel lining device 3 including a movable formwork 4 and a concrete supply part 5 is disposed inside an inner peripheral wall surface 2 of a tunnel 1. The tunnel lining device 3 is installed in the tunnel 1 in itself and is movably installed along a guide frame 6 having a profile similar to the inner peripheral wall surface 2 of the tunnel 1, whereby the movable platen 4 of the tunnel lining device 3 is separated from the inner peripheral wall surface 2 of the tunnel 1 with a gap 7 interposed therebetween and is movable while facing the inner peripheral wall surface 2. Therefore, when forming a concrete wall as a primary lining wall, for example, the tunnel lining device 3 is disposed at the lowermost portion of the inner peripheral wall surface 2 adjacent to the bottom surface 8 of the tunnel 1, and fresh concrete 10 is supplied from the nozzles 9 of the concrete supply unit 5 to the gap 7 between the movable form 4 and the inner peripheral wall surface 2. After the concrete in this portion is cured, the tunnel lining device 3 is moved upward, a new gap 7 is formed between the movable form 4 and the inner peripheral wall surface 2 in the upper position of the cured concrete, and fresh concrete 10 is filled in this new gap 7 to cure it. This operation is repeatedly performed to construct a lining wall. The remaining part of the roof 11 of the tunnel 1 is shown by the centre line in the figure, and the concrete is pressed in from both sides of the tunnel 1, and in the final stage the concrete is pressed in against the roof 11, which is operationally desirable.
On the one hand, the movable platen 4 includes a support frame 12, and a belt 14 is suspended on the support frame 12 while a plurality of rotary rollers 13 are hinged, and one side of the gap 7 is directly divided by the belt 14.
However, the belt 14 in the movable form 4 is a flat surface substantially parallel to the inner peripheral wall surface 2 of the tunnel 1, and there is a possibility that a sufficient pressure cannot be secured to the concrete 10 filled between the belt 14 and the inner peripheral wall surface 2, and the compressive strength of the concrete 10 is insufficient, so that a strong primary lining wall cannot be constructed. Further, the compressive strength of the concrete 10 is low, so that the strength of the concrete 10 is insufficient, and the concrete 10 falls due to its own weight, thereby failing to form a satisfactory primary lining wall.
The object of the present invention is to provide a moving device for a tunnel lining device, which can provide strength to concrete 10 filled between an inner peripheral wall 2 of a tunnel 1 and a moving form 4, and can also give compressive strength, and can prevent the concrete 10 from falling down due to its own weight even if the compressive strength is low.
The above object is achieved by the moving form of the present invention characterized in that a plurality of revolving rollers 13 are hinged to a support frame 12, a belt 14 is suspended so as to be movable along the inner peripheral wall surface 2 of the tunnel 1, and a filling space 7 for concrete 10 is defined between the inner peripheral wall surface 2, and in the moving form of a tunnel lining apparatus for continuous construction of a concrete wall as a primary lining, at least a part of the revolving rollers 13 suspending the belt 14 has a central portion with a larger diameter than both end portions and at least a part of the other revolving rollers has a larger diameter.
The invention is described below with reference to the accompanying drawings, which are not limited to the embodiments but include equivalents included in the dependent claims.

fig. 15 is a schematic perspective view of still another embodiment of the movable die plate according to the present invention.
Referring to fig. 1 and 2, in the moving apparatus of the tunnel lining apparatus according to the present invention, the 1 st rotating roller 13a among the plurality of rotating rollers 13a to 13e of the movable platen 4 facing the inner peripheral wall surface 2 of the tunnel 1 is formed in a circular bar shape having a uniform diameter. On the one hand, from the next 2 nd rotating roller 13b to the final 5 th rotating roller 13e, the central portion 13b 'to 13 e' thereof is larger than the diameter of the both end portions 13b 'to 13 e' and the diameter thereof is gradually increased from the central portion 13b 'to 13 e', and further, toward the final 5 th rotating roller 13e, the central portion 13b 'to 13 e' thereof has a gradually increased diameter, and on these rotating rollers 13a to 13e, an elastic and deformable belt 14 is preferably suspended, in which case the belt 14 has a shape corresponding to the contour of the entire rotating rollers 13a to 13e (see fig. 3). Thus, the concrete 10 filled in the gap 7 formed between the inner peripheral wall surface 2 of the tunnel 1 and the movable form 4 has the outer shape of the belt 14 corresponding to the contour of the entire rotating rollers 13a to 13e, and the surface of the concrete 10 is formed into a raised surface (see fig. 4). In this case, the concrete 10 is given sufficient compressive strength to provide strength to the constructed concrete wall.
In one aspect, the movable form of the tunnel lining apparatus according to the present invention may have various design changes. That is, as referring to fig. 5, the center portion 23a 'of the 1 st rotating roller 23a of the moving die plate 4 is larger in diameter than the both end portions 23a ″ in the present embodiment, and gradually increases in diameter toward the center portion 23 a'. Further, the following 2 nd to 5 th revolving rollers 23b to 23e are also the same in size and shape as the 1 st revolving roller 23a, compared with this. In the embodiment shown in FIG. 6, the 1 st and 2 nd revolving rollers 33a and 33b are formed in a circular bar shape having a uniform diameter, and the 3 rd to 5 th revolving rollers 33c to 33e have central portions 33c to 33e ' having a larger diameter than both end portions 33c ' to 33e ' and gradually increasing diameters toward 33c ' to 33e ', and further have the final 5 th revolving roller 33e having a central portion 33c ' to 33e ' with a gradually increasing diameter. In the embodiment of FIG. 7, the center portions 43a 'to 43 e' of all of the 1 st to 5 th revolving rollers 43a to 43e are larger in diameter than the both end portions 43a 'to 43 e' and gradually increase in diameter toward the center portions 43a 'to 43 e' and gradually increase in diameter toward the final 5 th revolving roller 43 e.
However, in each of the movable forms shown in fig. 5 to 7, the shape of the surface of the concrete 10 filled in the gap 7 with the inner peripheral wall surface 2 of the tunnel 1 is given to the raised shape corresponding to the contour of each of the turning roller subgroups, that is, the shape of the belt 14 having poor suspension in the turning roller subgroups is changed, and in any of the embodiments, a good compressive strength is given to the concrete 10 filled in the gap 7, and the concrete wall to be constructed can be sufficiently reinforced.
In the above embodiments, the number of the rotating rollers is described as 5, but the number of the rotating rollers can be increased or decreased as necessary. In addition, although the cross-sectional outer shape shown in the rotary roller having a larger central portion is changed linearly, it is also possible to give a curved cross-sectional outer shape as shown in fig. 8, and to give a raised shape having a concave curved surface to the concrete 10 filled in the gap 7 as shown in fig. 9, and further give a raised shape having a polygonal cross-sectional shape as shown in fig. 10, and to give a raised shape having a concave dish shape as shown in fig. 11.
Referring to fig. 12 and 13, in the movable platen 54 of the tunnel lining device 53 according to the present invention, a group of side plates 65 is erected on one end edge of a belt 63 suspended from a revolving roller 63. The side plate pieces 65 are divided into a plurality of tracking movements when the belt 64 rotates, and when the belt 64 is at any rotation position, the front ends of the side plate piece 65 group on the inner peripheral wall surface 2 side of the tunnel 1 can be in close contact with the inner peripheral wall surface 2. One end of the movable die plate 34 on which the side plate pieces 65 stand is oriented toward the excavation end surface side of the tunnel 1. Therefore, since the primary lining walls are formed in sequence in the advancing direction, the tip portions of the already constructed primary lining walls are placed on the excavation end face side and the opposite side of the tunnel 1, and the concrete 10 filled in the gap between the inner peripheral wall surface 2 of the tunnel 1 and the movable form 54 hardly flows out from the excavation end face side and the opposite side. On the other hand, according to the structure of fig. 12 and 13, since the concrete filled in the gap between the inner peripheral wall surface and the movable die plate 54 is restrained from flowing out from the excavation end surface side by the group of side pieces 65, the concrete 10 filled in the gap is cured in a state in which almost all of it does not flow out, and a primary lining wall without reducing the strength can be constructed. In addition, the side plate pieces 65 function as partitions for dividing a predetermined gap between the inner peripheral wall surface 2 of the tunnel 1 and the movable formwork 54 at the time of constructing the lining wall at one time.
In place of the structure shown in fig. 12 and 13, a storage rail 85 having a concave cross section is attached to one end of the tunnel 1 on the excavation end surface side of the belt 84 of the movable die plate 74 shown in fig. 14, and one or more air tubes 86, 86a (an example of two air tubes is shown) into which air, for example, can be charged are disposed between the storage rail 85 and the inner circumferential wall surface 2 of the tunnel 1. These air pipes 86 and 86a prevent the filled concrete 10 discharged from the nozzle 9 from flowing out from the excavation end face side of the tunnel 1 in the gap 7 between the inner peripheral wall surface 2 of the tunnel 1 and the movable die plate 74, and maintain the dimension between the inner peripheral wall surface 2 and the movable die plate 74, similarly to the group of side plates 65 of the embodiment of fig. 12 and 13.
Fig. 15 shows a movable form 94 which can smoothly fill the concrete 10 in the top portion 11 of the tunnel 1 after the concrete wall of the primary lining wall left at the top portion 11 of the tunnel 1 is constructed, when the operation of filling the concrete 10 in the gap 7 between the inner peripheral wall surface 2 of the tunnel 1 and the movable form is repeated. The movable die plate 94 is provided with a moving groove 105 which is open at the top of the tunnel 1 and extends in the axial direction of the tunnel 1, i.e., in the direction perpendicular to the drawing sheet, and a movable nozzle device 99 is provided in the moving groove 105. In addition, a belt 104 is suspended on the rotary roller 103 at a lower portion of the moving groove 105, and the belt is suspended at a position closing the moving groove 105. Due to the movable form 94, when the concrete 10 is filled in the gap between the inner peripheral wall surface 2 on the roof 11 of the tunnel 1 and the movable form 94, the concrete 10 dropped by its own weight can be hardly flowed out in the gap to maintain the curing, and a primary lining wall with no decrease in strength can be constructed.
The movable form of the tunnel lining apparatus according to the present invention configured as described above has a remarkable effect that the concrete filled in the gap between the inner peripheral wall surface of the tunnel and the movable form can be sufficiently reinforced, a high compressive strength can be maintained for the fresh concrete to be pressed in, the outflow of the concrete filled in the gap between the inner peripheral wall surface of the tunnel and the movable form due to its own weight is suppressed, and the strength can be surely prevented from being lowered.
