Abstract
The utility model discloses an underground works is sluicing device for outlet, the outlet is located in the soleplate in the underground works, its characterized in that the sluicing device include the sleeve pipe and with the chimney filter that the port is connected on the sleeve pipe, be provided with a switching valve in the sleeve pipe, just mud sand filter has in the chimney filter. The utility model has the advantages that, this sluicing device simple structure can effectively prevent to run off at the silt particle of sluicing in -process, and in drilling process, can effectively prevent gushing of groundwater.
Description
Technical field
This utility model relates to sluicing decompressor, is specifically related to a kind of underground engineering spilled water hole water draw-off.
Background technology
Gradually extending to underground with construction work at present, basement is increasingly deeper, and when sole plate absolute altitude is less than region water level elevation, sole plate will be by underground buoyancy of water.
In structure construction procedure, pressure-bearing drainage sump or spilled water hole are often set on sole plate, prevent institute's constructing structure deadweight to be insufficiently resistant to during buoyancy force of underground water cause structure entirety to float.But when offering drainage sump or spilled water hole on basement sole plate, a large amount of subsoil water will be caused to gush owing to needs drill sole plate, in this case, mostly use sand bag heap pressure, construction has in the case of retention of excessive fluid carry out, and it is the most inconvenient and difficult to cause to construction.And when sluicing decompression, subsoil water will be carried secretly a large amount of silt particle and discharge, the silt particle of excess is discharged and geology will be caused to endanger the soil layer below sole plate, causes even more serious potential safety hazard to upper building.
Summary of the invention
The purpose of this utility model be according to above-mentioned the deficiencies in the prior art in place of, a kind of underground engineering spilled water hole water draw-off is provided, this water draw-off has the chimney filter of silt particle filtering function by connecting on sleeve pipe, such that it is able to be prevented effectively from silt particle to cause loss during sluicing.
This utility model purpose realizes being completed by techniques below scheme:
A kind of underground engineering spilled water hole water draw-off, described spilled water hole is positioned in the sole plate of described underground engineering, it is characterised in that described water draw-off includes sleeve pipe and the chimney filter being connected with described sleeve upper end mouth, is provided with a controlled valve in described sleeve pipe.
Described sleeve pipe is fixedly installed in the sole plate of described underground engineering, the setting corresponding with the spilled water hole in described sole plate of its lower port.
Controlled valve in described sleeve pipe is arranged at above the sole plate of described underground engineering.
Described chimney filter has silt particle filter.
The utility model has the advantages that, this water draw-off simple in construction, can effectively prevent the silt particle during sluicing to run off；And in boring procedure, can effectively prevent gushing of subsoil water.
Accompanying drawing explanation
Fig. 1 is water draw-off structural representation in this utility model；
Fig. 2 is the work progress schematic diagram of water draw-off in this utility model.
Detailed description of the invention
Feature of the present utility model and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, in order to the understanding of technical staff of the same trade:
Such as Fig. 1-2, in figure, labelling 1-11 is respectively as follows: sole plate 1, groove 2, sleeve pipe 3, controlled valve 4, angle bar 5, screw 6, cement mortar 7, drilling rod 8, boring 9, soil layer 10, chimney filter 11.
Embodiment:
As shown in Figure 1, the present embodiment is specifically related to a kind of underground engineering spilled water hole water draw-off, and this water draw-off is arranged in sole plate 1, including sleeve pipe 3, the lower port of sleeve pipe 3 is fixedly installed in sole plate 1, and its upper port is then connected with the chimney filter 11 with filtering function；Being provided with a controlled valve 4 in sleeve pipe 3, this controlled valve 4 is above the upper surface of sole plate 1, in order to it is carried out opening and closing operation by staff.
As shown in Figure 1, 2, in the present embodiment, the construction method of water draw-off comprises the steps:
(1) first, a groove 2 is offered on sole plate 1 in basement, this groove 2 is stepped in two-part from large to small, it should be noted that, groove 2 does not drill sole plate 1, being reserved with certain thickness base plate on sole plate 1, in case water is gushed in bottom soil layer 10, the degree of depth of offering of groove 2 accounts for the 1/2 3/4 of sole plate 1 thickness；
(2) after, choose a sleeve pipe 3 with controlled valve 4, the lower port of sleeve pipe 3 is inserted groove 2 inner bottom part, but is not passed through sole plate 1；After being inserted into, utilize angle bar 5 to be connected with fixing between groove 2 by sleeve pipe 3, i.e. the side plate of angle bar 5 is fixed with sleeve pipe 3 sidewall weld, and another side plate then passes through screw 6 and is screwed and is connected with the epimere base plate of groove 2；Sleeve pipe 3 top is above the surface of sole plate 1, and controlled valve 4 should be arranged at sleeve pipe 3 top so that it is carried out opening and closing operation by staff；
(3) in order to further sleeve pipe 3 is fixed spacing, cement injection mortar 7 in the space between sleeve pipe 3 outer wall and groove 2；
(4) after the cement mortar 7 until aforementioned perfusion solidifies and reaches some strength, open the controlled valve 4 in sleeve pipe 3, then by a drilling rod 8 deeply to sleeve pipe 3 inner bottom part, and utilize this drilling rod 8 to offer boring 9, drill sole plate 1 until in soil layer 10 below, forming spilled water hole；
(5) after treating spilled water hole construction, the subsoil water in soil layer 10 will produce prominent emerge in large numbers as, therefore rapidly on carry drilling rod 8 and depart from sleeve pipe 3, and closing switch valve 4 immediately；
(6) upper port at sleeve pipe 3 is socketed a chimney filter 11 with filtering function, and the most external drain water circuit of chimney filter 11, wherein, this chimney filter 11 can carry out anti-filter to the silt particle in subsoil water, prevents silt particle to run off.
As shown in Figure 1, in the present embodiment, the method for work of water draw-off is: when utilizing water draw-off to carry out sluicing decompression, open the controlled valve 4 in sleeve pipe 3, below sole plate 1, the subsoil water in soil layer 10 discharges through sleeve pipe 3, the subsoil water discharged is when through filter tube 11, the silt particle of entrained with in subsoil water can be carried out anti-filter, to prevent the loss of silt particle in soil layer 10, it is to avoid cause geology to endanger.
