Detailed Description
Example 1
As shown in fig. 1-2, the embodiment provides a novel water intercepting system for a subway tunnel deformation joint, which comprises a deformation joint liner plate 1 and a water receiving box 2, wherein the deformation joint liner plate 1 made of polyethylene foam plate is plugged into the deformation joint, an isolation membrane 3 made of a PE film with the thickness of 0.2-0.3mm is arranged at the bottom of the deformation joint liner plate 1, and a sealant 4 is coated at the bottom of the isolation membrane 3; the water receiving box 2 of 1mm thick corrosion resistant plate material is provided with fixed plate 5 along length direction's both sides, and the cladding has butyl rubber 6 and butyl rubber 6 to scribble the putty with the one side that the concrete structure 7 in tunnel contacted on the fixed plate 5, and fixed plate 5 passes through the screw 8 to be fixed on the concrete structure 7 in tunnel. The putty and the sealant 4 used in the embodiment are conventional products in the field, and are not described herein again.
During construction, according to the size Q of water discharged per linear meter of underground water after tunnel excavation at a deformation joint position, the size of leakage water Q at the position after structure pouring is estimated, and the relationship between the size Q and the leakage water Q is B multiplied by Q (the deformation joint is positioned on a flat slope or a slope top of a line) or Q is 2 multiplied by B multiplied by Q/S (the deformation joint is positioned on the slope bottom of the line). Wherein B is a coefficient of variation, the coefficient is obtained by local same geological statistics according to geological values of different regions, and S is the length of the deformation joint. And determining the width 2b and the depth h of the water receiving box 2 according to the size of q, wherein the relationship between the width 2b and the depth h is 2b multiplied by h multiplied by S, 2b is more than or equal to 100mm and less than or equal to 150mm, and h is more than or equal to 30mm and less than or equal to 50 mm. Therefore, the size of the water receiving box 2 can be reasonably set according to the size of water leakage of different stratums, and the construction cost is reduced.
The size of the water receiving box 2 is calculated by the method, and the water receiving box 2 is prefabricated in a factory or a construction site. The deformation joint liner plate 1 is stuffed in when reinforcing steel bars on two sides of a deformation joint are bound, and an isolation film 3 and a sealant 4 are smeared at the bottom of the deformation joint liner plate 1 after a structure is poured. And then, when the tunnel concrete structures 7 on the two sides of the deformation joint are poured, reserving the mounting structure of the water receiving box 2 (namely, a wood block to reserve the mounting space of the water receiving box 2). After pouring is finished, the water receiving box 2 is fixed on a concrete structure 7 by using screws 8 at the positions of the fixing plates 5 on the two sides of the water receiving box 2, and then the installation of the whole water interception system is finished.
The water interception system of the embodiment has the function of blocking underground water by plugging the deformation joint liner plate 1 in the deformation joint. And because the fixing plates 5 at the two sides of the water receiving box 2 are coated with the butyl rubber 6 and the butyl rubber 6 is coated with putty, the water receiving box 2 can be attached to the concrete structure 7 more tightly after being fixed on the concrete structure 7, thereby playing a good plugging role and solving the problem that the water receiving box 2 in the past design is a layer of stainless steel plate fixed by the screw 8, and because the screw 8 and the steel plate are both made of steel, the contact position is bound to have a seam, so that the water receiving effect is poor.
Example 2
On the basis of the embodiment 1, a sealant 4 is coated between the outer side of the water receiving box 2 and a concrete structure 7 of the tunnel. After the water receiving box 2 is fixed on the concrete structure 7 by the screw 8, the sealant 4 is filled in the gap between the outer side of the water receiving box 2 and the concrete structure 7, so that the effect of plugging the gap between the water receiving box 2 and the concrete structure 7 can be achieved, and the outflow of leakage water is reduced.
Although the present invention has been described in detail by referring to the drawings in conjunction with the preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made on the embodiments of the present invention by those skilled in the art without departing from the spirit and substance of the present invention, and these modifications or substitutions are intended to be within the scope of the present invention/any person skilled in the art can easily conceive of changes or substitutions within the technical scope of the present invention.
