Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation pit waterproofing technology, specifically a waterproof structure for foundation pits in building construction. Background Technology
[0002] Foundation pit waterproofing refers to the series of waterproofing measures implemented during the construction of foundation pit projects to ensure that the surrounding environment is protected from the infiltration of groundwater or rainwater. The purpose of foundation pit waterproofing is to protect the stability of the foundation pit soil and prevent water from adversely affecting the underground structure or the surrounding environment. It is particularly important in projects such as underground structure construction, infrastructure construction, underground parking lots, and underground shopping malls.
[0003] However, existing technologies for waterproofing foundation pits typically rely on waterproof membranes or geotextiles. While waterproof membranes are inexpensive, they suffer from poor durability and waterproofing, while geotextiles are prone to damage and destruction, leaving room for improvement. Utility Model Content
[0004] The purpose of this utility model is to provide a waterproof structure for foundation pits in building construction, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for building construction pits, including a water-retaining seat and a connecting seat, wherein a water-retaining plate is movably connected inside the water-retaining seat, and the connecting seat is movably connected to the water-retaining seat through a connector.
[0006] As a further embodiment of this utility model: a waterproof structure for building construction pits, wherein a movable plate is fixedly connected to one side of the water-blocking plate, a spring rod is fixedly installed inside the water-blocking seat, and the movable plate is movably connected to the spring rod.
[0007] As a further embodiment of this utility model: a waterproof structure for building construction pits, wherein the connecting seat includes a seat body and a corrugated expansion layer, and two sets of seat bodies are respectively disposed at the ends of the corrugated expansion layer and fixedly connected to the corrugated expansion layer.
[0008] As a further embodiment of this utility model: a waterproof structure for building construction pits, wherein the connecting member includes a connecting block and a screw, the interior of the base body has a second mating groove, the interior of the water-blocking base has a first mating groove, half of the connecting block is adapted to the second mating groove, the other end of the connecting block is adapted to the first mating groove, one end of the screw is screwed into the second mating groove, and the other end of the screw is screwed into the first mating groove.
[0009] As a further embodiment of this utility model: a waterproof structure for building construction pits, wherein a clamp is fixedly installed inside the water-retaining seat, and the seat body is adapted to the clamp.
[0010] As a further embodiment of this utility model: a waterproof structure for building construction pits, wherein a knob is fixedly connected to one end of the screw that passes through the base, and an anti-detachment pad is fixedly connected to the outer periphery of the screw located in the interlayer between the connecting block and the base.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. Since the water-blocking seat has a water-blocking plate inside, the connecting seat is movably connected to the water-blocking seat through a connecting piece. Specifically, the connecting seat includes a seat body and a corrugated expansion layer. Two sets of seat bodies are respectively set at the ends of the corrugated expansion layer and fixedly connected to the corrugated expansion layer. Therefore, during waterproofing operations, the corrugated expansion layer can be used to change the angle or length of the equipment, adapt to the size of the waterproof foundation pit, and meet the requirements of waterproofing operations.
[0013] 2. Because the base body has a second mating groove inside, and the water-blocking seat has a first mating groove inside, half of the connecting block is adapted to the second mating groove, and the other end of the connecting block is adapted to the first mating groove. One end of the screw is screwed into the second mating groove, and the other end of the screw is screwed into the first mating groove. Therefore, the connecting parts will not fall off the connecting seat and can be avoided from being lost. In addition, a clamp is fixedly installed inside the water-blocking seat, and the base body is adapted to the clamp. Therefore, when the connecting seat and the connecting parts are not in use, they can be assembled together with the water-blocking seat as a whole, reducing the probability of loss.

[0024] Since the water-blocking seat 1 is internally connected to the water-blocking plate 2, the connecting seat 5 is movably connected to the water-blocking seat 1 through the connecting piece 6. Specifically, the connecting seat 5 includes a seat body 51 and a corrugated expansion layer 52. Two sets of seat bodies 51 are respectively located at the ends of the corrugated expansion layer 52 and are fixedly connected to the corrugated expansion layer 52. Therefore, during waterproofing operations, the angle or length of the equipment can be changed using the corrugated expansion layer 52 to adapt to the size of the waterproofing pit and meet the requirements of waterproofing operations.

[0029] The working principle of this utility model is as follows: Since the water-blocking seat 1 is movably connected to the water-blocking plate 2, the connecting seat 5 is movably connected to the water-blocking seat 1 through the connecting piece 6. Specifically, the connecting seat 5 includes a seat body 51 and a corrugated expansion layer 52. Two sets of seat bodies 51 are respectively disposed at the ends of the corrugated expansion layer 52 and are fixedly connected to the corrugated expansion layer 52. Therefore, during waterproofing operations, the angle or length of the equipment can be changed using the corrugated expansion layer 52 to adapt to the size of the waterproofing pit and meet the requirements of waterproofing operations.
[0030] Because the base 51 has a second mating groove 53 inside, and the water-blocking seat 1 has a first mating groove 11 inside, half of the connecting block 61 is adapted to the second mating groove 53, and the other end of the connecting block 61 is adapted to the first mating groove 11. One end of the screw 62 is screwed into the second mating groove 53, and the other end of the screw 62 is screwed into the first mating groove 11. Therefore, the connecting piece 6 will not fall off from the connecting seat 5 and can be avoided from being lost. In addition, a clamp 7 is fixedly installed inside the water-blocking seat 1, and the base 51 is adapted to the clamp 7. Therefore, when the connecting seat 5 and the connecting piece 6 are not in use, they can be assembled together with the water-blocking seat 1 as a whole, reducing the probability of loss.
