Abstract
The invention discloses a method of connection between tunnel waterproof plates. The method comprises the following steps of (1) paving the waterproof plates on the outline plane of a tunnel in a raising way; (2) turning the sides of the waterproof plates outward along the edges of the waterproof plates to form flanged sides; (3) welding the flanged sides of every two adjacent waterproof plates so as to connect the two waterproof plates together. According to the method of connection provided by the invention, a traditional connection technology is broken through; the use is convenient; the waterproof plates can be effectively connected together; the construction efficiency is high; the quality is reliable.
Description
Technical field
The present invention relates to method of attachment between a kind of plate, specifically method of attachment between a kind of anchor bar of waterproof plate in tunnels.
Background technology
At present, the connection of splash guard two interannulars (i.e. two interblocks) all adopts sweat soldering method, and plane overlap joint 10-15 centimetre between splash guard, then adopts the sweat soldering technique of creeping that overlap is welded together.
Due to the particularity of tunneling operation environment, adopt this connection technique also to have many problems that need solution.Constructing tunnel space is an enclosure space, because behind, tunnel sprayed mortar face cannot keep smooth, unsettled behind in the time of causing splash guard welding, cannot provide support behind to climbing weldering, therefore cannot, after hot melt, apply effective pressure, have a strong impact on the welding quality of anchor bar of waterproof plate in tunnels, very easily cause two ring splash guard junctions to occur waterproof weak link, easily cause leaking, this problem is the main mass defect of current anchor bar of waterproof plate in tunnels construction waterproof.
Summary of the invention
Technical problem to be solved by this invention is to provide method of attachment between a kind of anchor bar of waterproof plate in tunnels, adopts the method to make the connection of splash guard two interannulars become convenient, and quality of connection improves greatly.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A method of attachment between anchor bar of waterproof plate in tunnels, it comprises the following steps:
(1) splash guard lifting is laid on tunnel contour face;
(2) the formation flanging that waterproof edges of boards turned up along splash guard edge;
(3) flanging of adjacent two splash guards is welded together, thereby two splash guards are linked together.
In order not affect the thickness of later stage filling concrete, after described step (3), also comprise by the flanging welding together the step near splash guard to any edge contraction.
The both sides of described splash guard are respectively arranged with embossings more than twice, and described flanging is for turning up waterproof edges of boards along waterproof edges of boards first embossing edge formation.
Described embossing is semicircle shape, and embossing width is 1～15cm, and the embossing degree of depth is 0.5～1.5cm.
Described waterproof edges of boards first embossing edge is 5～20cm far from splash guard back gauge, and flanging length is 5～20cm, preferably 15cm.
In described step (3), on the flanging welding together, hot melt has bend, and described crooked position is in the junction of flanging and splash guard first embossing.
The both sides of described splash guard are respectively arranged with twice embossing.
Method of attachment of the present invention breaks through traditional connection process, easy to use, can effectively splash guard be linked together, and efficiency of construction is high, reliable in quality.

Fig. 5 is that the flanging with bend is folded to a side schematic diagram naturally.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Between anchor bar of waterproof plate in tunnels of the present invention, method of attachment comprises the following steps:
(1) splash guard lifting is laid on tunnel contour face;
(2) the formation flanging that waterproof edges of boards turned up along splash guard edge.
This step is the committed step of the inventive method, the present embodiment adopts following steps to realize the formation (the inventive method is not limited to following flanging formation method) of flanging: as shown in Figure 1, before splash guard lifting is laid, on the both sides of described splash guard, difference precompressed forms embossings more than twice, preferred precompressed twice embossing: first embossing 1, second embossing 2, (turning up is not to tunnel contour face one side, but to its contrary side) forms in order waterproof edges of boards being turned up along waterproof edges of boards first embossing 1 edge for flanging 3.
The embossing of precompressed provides possibility for splash guard forms flanging 3, and the embossing of precompressed forms nature groove 4 on splash guard, and this groove 4, can effectively ooze tunnel contour face moisture content lower or that produce and discharge across the two ends in tunnel along tunnel contour face direction.
Described embossing is semicircle shape, and embossing width is 1～15cm, generally selects 2～5cm; The embossing degree of depth is 0.5～2cm, generally selects 0.5～1cm; Described waterproof edges of boards first embossing 1 edge is 5～20cm far from splash guard back gauge, and flanging length is 5～20cm, can select 15cm.
(3) flanging of adjacent two splash guards is welded together, thereby two splash guards are linked together.
This step flanging that forms of above-mentioned flanging welds the condition of providing convenience, for providing the welding that extruding needs, welding pushes space, as shown in Figure 2, along the direction of arrow in Fig. 2, push welding, adopt two-sided extrusion technique, for the welding of splash guard provides reliable pressure guarantee, improve welding quality and waterproof reliability.Flanging 3 approximately perpendicular to or perpendicular to splash guard integral slab face, very convenient like this two flangings 3 are welded together.As adopt extruding hot-melt welding machine, on flanging, hot melt, extruding welding form soldered 5 easily, generally on flanging 3, form twice soldered.While so just having avoided splash guard welding, behind is unsettled cannot provide support behind to climbing weldering, cannot, in the problem of the after-applied effective pressure of hot melt, guarantee the quality of welding.
After two flangings 3 welding, by the flanging welding together 3 to any edge contraction near splash guard, as shown in Figure 3.The flanging 3 welding together like this can affect the thickness of later stage filling concrete.
For the ease of by the flanging welding together 3 to any edge contraction near splash guard, on the flanging 3 welding together, hot melt has bend 6, as shown in Figure 4, described bend 6 is positioned at the junction (being flanging 3 roots) of flanging 3 and splash guard first embossing.The bend 6 that hot melt forms is after cooling, and flanging 3 will be drawn close to crooked rightabout naturally along bend, thereby naturally realize to an edge contraction near splash guard, as shown in Figure 5.
Above-described embodiment does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
