Description

Technical Field

[0001] The present application relates to the field of building waterproofing, and in particular to an anti-leakage structure for basement waterproofing projects. Background Art

[0002] With the rapid development of my country's economy, the construction of building drainage facilities is also constantly improving. The accumulated water on the ground in water rooms such as bathrooms and kitchens is discharged to the outside through drainage pipes. The drainage pipes generally pass through the floor concrete and lead from under the floor to the drainage main pipe. In the basement of the construction project, the connection from the ground to the drainage pipe also needs to take necessary waterproofing measures.

[0003] After the poured concrete is hydrated and heated, it shrinks, and a tiny gap will appear between the drainage pipes embedded in the concrete and the concrete. When the ground waterproofing is not done well or there is a tiny gap between the waterproofing and the drainage pipes, the accumulated water on the ground will slowly seep into the floor slab through the tiny gap between the drainage pipes and the concrete, and the water that penetrates into the floor slab will become moldy and rot if it does not flow for a long time. The moldy and rotten stagnant water will be soaked in the floor slab for a long time, which will directly affect the floor quality of the basement, causing peeling, bulging or cracks, so it needs to be improved. Summary of the invention

[0004] In order to improve the problem that water easily enters the gap between the drainage pipe and the concrete, causing the basement floor to peel, bulge and crack, the present application provides an anti-leakage structure for basement waterproofing projects.

[0005] The anti-leakage structure of a basement waterproofing project provided in this application adopts the following technical solution:

[0006] A leakage-proof structure for a basement waterproofing project, comprising:

[0007] A drainage pipe, wherein a mounting hole is opened on the concrete layer, and the drainage pipe is inserted into the mounting hole;

[0008] A blocking ring is sleeved on the drain pipe, the inner side wall of the blocking ring is connected to the drain pipe, and the outer side wall is connected to the inner wall of the mounting hole. The blocking ring is used to block the gap between the drain pipe and the inner wall of the mounting hole.

[0009] By adopting the above technical solution, when there is water on the floor of the concrete layer surface of the basement, the water flows into the installation hole, part of the water falls on the blocking ring, and the other part of the water directly enters the drain pipe from the opening of the drain pipe until it is discharged along the drain pipe. The water falling on the blocking ring slides from the edge of the blocking ring into the drain pipe and is then discharged from the drain pipe, so that the water will not penetrate into the gap between the installation hole and the side wall of the drain pipe, but soak in the concrete, that is, the quality of the floor of the concrete layer surface of the basement will not be affected, and no peeling, bulging or cracking will occur.

[0010] Optionally, a connecting hole is opened on the side wall of the drain pipe, the inner edge of the sealing ring is inserted into the connecting hole and can move in the connecting hole, and the outer edge of the sealing plate is sealed and fixed to the inner wall of the mounting hole.

[0011] By adopting the above technical solution, the sealing ring connects the drain pipe and the inner wall of the installation hole. When a tiny crack is generated between the concrete layer and the drain pipe, the distance between the drain pipe and the inner wall of the installation hole becomes larger, so that the concrete layer drives the sealing ring to move away from the central axis of the drain pipe, so that the side of the sealing ring close to the inner wall slides in the connecting hole to meet the distance between the inner wall of the installation hole and the drain pipe, so that when the slow-setting soil moves, the gap between the inner wall of the installation hole and the drain pipe is always blocked by the sealing ring, and no water can enter directly.

[0012] When the water on the floor on the upper surface of the concrete layer flows into the installation hole and falls on the sealing ring, the water flows along the sealing ring to the drain pipe until the water reaches the edge of the sealing ring close to the drain pipe. At this time, the water will directly enter the drain pipe from the end opening of the drain pipe, thereby draining the water on the floor.

[0013] Optionally, a limiting ring is provided on the inner edge of the blocking ring, a limiting groove extending in the radial direction of the blocking ring is opened on the inner wall of the connecting hole, and the limiting ring is inserted in the limiting groove and can move in the limiting groove.

[0014] By adopting the above technical solution, when the sealing ring moves in the connecting hole, the limiting ring moves in the limiting groove, and when the limiting ring abuts against the inner wall of the limiting groove on the side away from the central axis of the drain pipe, the limiting ring is restricted from moving in the direction away from the drain pipe, that is, the limiting ring cannot be completely pulled out of the connecting hole, thereby increasing the stability of the connection between the sealing ring and the drain pipe.

[0015] Optionally, a water stop strip is fixed on the inner wall of the connecting hole, and the side wall of the water stop strip away from the inner wall of the connecting hole is in contact with the side wall of the sealing ring.

[0016] By adopting the above technical solution, when water falling on the sealing ring moves along the sealing ring to the drain pipe, the water will reach the edge of the sealing ring and enter the connecting hole. The water stop strip absorbs part of the water and expands, tightly clinging to the side wall of the sealing ring, thereby increasing the sealing between the sealing ring and the inner wall of the connecting hole, making it difficult for water to leak from the bottom wall of the sealing ring and the inner wall of the connecting hole to the bottom of the sealing ring, thereby making it difficult for water to soak into the concrete, that is, the floor quality on the surface of the concrete layer is not easily affected.

[0017] Optionally, a push assembly is provided on the inner wall of the mounting hole, the push assembly is connected to the bottom wall of the blocking ring and is used to drive the blocking ring to bulge or dent, and the push assembly includes:

[0018] A push tube is vertically arranged and has an opening at the top, and the top end of the push tube passes through a sealing ring and is sealed and fixed to the sealing ring;

[0019] A positioning plate, fixed on the inner wall of the mounting hole and located below the blocking ring;

[0020] A spring is sleeved on the push tube, one end of the spring is fixed to the push tube, and the other end is fixed to the side wall of the positioning plate close to the blocking ring.

[0021] By adopting the above technical scheme, in the initial state, under the elastic force of the spring, the push tube drives the sealing ring to move upward, and the positions of the two sides of the sealing ring are fixed, so that the sealing ring is in a convex state, that is, the middle of the sealing ring is high and the two sides are low. When water falls on the sealing ring, it will move along the top wall of the sealing ring to the low points on both sides of the sealing ring, so that the water on the sealing ring slides from the edge of the sealing ring into the drain pipe, and then is discharged from the drain pipe, so that the water will not penetrate into the gap between the installation hole and the side wall of the drain pipe, but soaked in the concrete, that is, the quality of the floor on the surface of the basement concrete layer will not be affected, and then there will be no peeling, bulging or cracking.

[0022] When water falls on the sealing ring, water enters the jacking pipe from the top opening of the jacking pipe, thereby increasing the weight of the jacking pipe itself. The water gradually increases, the jacking pipe falls, compressing the spring, and at the same time driving the sealing ring to move downward until the sealing ring is in a concave state, so that when the water on the floor on the upper surface of the concrete layer reaches the installation hole, the sealing ring tilts downward on the side close to the edge of the installation hole, and will be at the edge of the installation hole, thereby facilitating the water to be guided into the installation hole and into the drain pipe, avoiding moisture from being retained on the floor on the surface of the concrete layer, causing the floor to be slippery or water to accumulate.

[0023] Optionally, a mounting plate is fixed on the inner wall of the mounting hole, the mounting plate is located between the sealing ring and the positioning plate, and the push tube passes through the mounting plate.

[0024] By adopting the above technical solution, when the push tube moves up and down, it is restricted by the two and a half pieces of the positioning plate and the mounting plate, so that the push tube always maintains a vertical state, thereby increasing the stability of the push tube movement.

[0025] Optionally, a water outlet assembly is provided at the bottom of the jacking tube, and the water outlet assembly is used to discharge water in the jacking tube.

[0026] By adopting the above technical scheme, when water enters the jacking pipe and drives the sealing ring from a convex state to a concave state, the water outlet assembly is used to discharge the water in the displacement pipe, so that the spring recovers its deformation, drives the jacking pipe to move upward, and makes the sealing ring become a convex state again, and the water continues to fall on the sealing ring, causing the sealing ring to be concave again, and this reciprocating process makes the sealing ring move in a wave shape, and when the sealing ring is in a concave state, the sealing ring can hold the water to accumulate force, and when the sealing ring becomes convex, it is convenient to bounce the water retained on the sealing ring into the drainage pipe, so that it is not easy for water to remain on the sealing ring for a long time, thereby improving the drainage efficiency.

[0027] Optionally, the water outlet component includes:

[0028] A water storage box is fixed at the bottom end of the push tube and is in communication with the push tube. The water storage box is located below the positioning plate. A water outlet hole is formed through the bottom wall of the water storage box. A sealing component for blocking the water outlet hole is provided in the water storage box.

[0029] A water outlet pipe is arranged on the side wall of the drain pipe and is communicated with the drain pipe. The water outlet pipe is fixedly connected to the positioning plate through a positioning rod. The water outlet pipe can be inserted into the water outlet hole and is communicated with the water storage box.

[0030] By adopting the above technical solution, the water storage box increases the volume of water that can be contained by the push tube. That is, the weight of the push tube is increased so that the push tube can squeeze the spring and drive the blocking ring to move downward until the blocking ring is in a concave state. In this process, the water storage box continues to move downward until the water outlet pipe is inserted into the water outlet hole. At this time, the end of the water outlet pipe abuts against the sealing component, and the weight of the push tube continues to drive the downward movement, so that the water outlet pipe is relatively deep into the water storage box, so that the water outlet pipe pushes the sealing component until the sealing component is in an open state, that is, the water storage box and the water outlet pipe are connected, so that the water in the water storage box can quickly enter the water outlet pipe, and then follow the water outlet pipe to reach the drain pipe.

[0031] When the water in the push tube is reduced to a point where the weight of the push tube is insufficient to overcome the elastic force of the spring, the spring pushes the push tube upward and the sealing ring returns to its original convex state. At this time, the water outlet pipe is relatively pulled out of the water outlet hole, and the sealing component re-seals the water outlet hole, allowing the water storage box to store water. When the water storage box and the push tube store more water and become heavier and move downward, the water outlet pipe will be inserted into the water outlet pipe again to draw out the water in the water storage box and the push tube, and the above steps are repeated to achieve continuous up and down fluctuations of the sealing ring.

[0032] Optionally, the closing assembly includes two closing plates relatively arranged in the water storage box, wherein the sides of the two closing plates away from each other are hinged on the inner wall of the water storage box and are located at the opening of the water outlet, and the side walls of the two closing plates close to each other abut against each other to block the water outlet.

[0033] By adopting the above technical solution, after the water outlet pipe is inserted into the water outlet hole, the end wall of the water outlet pipe abuts against the position where the two closing plates abut against each other, and the water outlet pipe continues to penetrate into the water storage box, so that the two closing plates are simultaneously subjected to an upward thrust, causing the two closing plates to gradually separate, thereby causing a gap to appear between the two closing plates, and the water outlet hole loses the shielding of the closing plate, so that the water storage box is connected to the water outlet pipe through the water outlet hole. At this time, the water in the water storage box and the push tube can flow into the water outlet pipe and reach the drain pipe along the water outlet pipe, thereby completing the discharge of water in the water storage box and the push tube.

[0034] Optionally, a receiving cover is fixed on the water outlet pipe, and the radial outlet pipe in the receiving cover gradually increases at one end away from the drain pipe. When the end of the water outlet pipe is inserted into the water outlet hole, the receiving cover abuts against the bottom wall of the water storage box. A water inlet hole is opened through the side wall of the water outlet pipe, and the water inlet hole is located inside the receiving cover.

[0035] By adopting the above technical scheme, when the water outlet pipe is inserted into the water outlet hole to push the closing plate, the water outlet pipe receives the water flowing out from the gap between the two closing plates, and the closing plate is gradually separated from the inner wall of the water storage box during rotation, and the water in the water storage box is easy to leak out. The receiving cover receives the water flowing out from between the water outlet pipe and the inner wall of the water outlet hole, and the water in the receiving cover finally enters the water outlet pipe through the water inlet hole, so that the water is not easy to enter the concrete outside the drain pipe, that is, the quality of the floor represented by the concrete layer will not be affected, and thus there will be no peeling, bulging or cracking.

[0036] In summary, the present application includes at least one of the following beneficial effects:

[0037] 1. When there is water on the basement floor, the water flows into the installation hole, part of the water falls on the sealing ring, and the other part of the water directly enters the drain pipe from the opening of the drain pipe until it is discharged along the drain pipe. In the initial state, the jacking assembly makes the sealing ring convex, that is, the middle of the sealing ring is high and the two sides are low. When water falls on the sealing ring, it will move along the top wall of the sealing ring to the low points on both sides of the sealing ring, so that the water on the sealing ring slides from the edge of the sealing ring into the drain pipe, and then is discharged from the drain pipe, so that the water will not penetrate into the gap between the installation hole and the side wall of the drain pipe, but soaked in the concrete, that is, the quality of the basement floor will not be affected, and no peeling, bulging or cracking will occur;

[0038] 2. The sealing ring connects the drain pipe and the inner wall of the installation hole. When cracks appear between the concrete layer and the drain pipe, the distance between the drain pipe and the inner wall of the installation hole becomes larger, so that the concrete layer drives the sealing ring to move away from the central axis of the drain pipe, so that the side of the sealing ring close to the inner wall slides in the connecting hole to meet the distance between the inner wall of the installation hole and the drain pipe. When the slow-setting soil moves, the gap between the inner wall of the installation hole and the drain pipe is always blocked by the sealing ring, and no water can enter directly.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-4 This application is described in further detail.

[0045] The present application embodiment discloses a leakage-proof structure for basement waterproofing. Figure 1 and Figure 2 The anti-leakage structure of the basement waterproofing project includes a drain pipe 20 buried in the concrete layer 10 of the basement, a mounting hole 11 is opened on the floor of the surface of the concrete layer 10, the drain pipe 20 is located in the mounting hole 11, a sealing ring 30 is sleeved on the drain pipe 20, the sealing ring 30 is located in the mounting hole 11, and the sealing ring 30 is an elastic rubber diaphragm. Specifically, the outer wall of the sealing ring 30 is fixed in the mounting hole 11, a connecting hole 21 is opened on the outer wall of the drain pipe 20, and the inner edge of the sealing ring 30 is inserted into the connecting hole 21 and can move in the connecting hole 21, so that the sealing ring 30 fills the gap between the drain pipe 20 and the inner wall of the mounting hole 11. A water stop strip 211 is fixed on the inner wall of the connecting hole 21, and the side of the water stop strip 211 away from the inner wall of the connecting hole 21 abuts against the side wall of the sealing ring 30.

[0046] When tiny cracks are generated between the concrete layer 10 and the drain pipe 20, the distance between the drain pipe 20 and the inner wall of the mounting hole 11 becomes larger, that is, the inner diameter of the mounting hole 11 becomes larger, so that the concrete layer 10 drives the sealing ring 30 to expand and deform. At the same time, the sealing ring 30 also moves in a direction away from the central axis of the drain pipe 20, so that the side of the sealing ring 30 close to the inner wall slides in the connecting hole 21 to meet the distance between the inner wall of the mounting hole 11 and the drain pipe 20, so that when cracks are generated between the concrete layer 10 and the drain pipe 20, the gap between the inner wall of the mounting hole 11 and the drain pipe 20 is always blocked by the sealing ring 30.

[0047] Reference Figure 1 and Figure 2 When there is water on the basement floor, the water flows into the installation hole 11, part of the water falls on the sealing ring 30, and the other part of the water directly enters the drain pipe 20 from the opening of the drain pipe 20 until it is discharged along the drain pipe 20. The sealing ring 30 prevents the water from penetrating into the gap between the installation hole 11 and the side wall of the drain pipe 20, but soaks in the concrete, that is, the quality of the basement floor will not be affected, and no peeling, bulging or cracking will occur.

[0048] When water falling onto the sealing ring 30 moves along the sealing ring 30 toward the drain pipe 20, the water will reach the edge of the sealing ring 30 and enter the connecting hole 21. The water stop strip 211 absorbs part of the water and expands, tightly clinging to the side wall of the sealing ring 30, thereby increasing the sealing between the sealing ring 30 and the inner wall of the connecting hole 21, making it difficult for water to leak from between the bottom wall of the sealing ring 30 and the inner wall of the connecting hole 21 to the bottom of the sealing ring 30, further making it difficult for water to soak into the concrete, that is, the floor quality of the surface of the concrete 10 is not easily affected.

[0049] Reference Figure 1 and Figure 2 In order to prevent the sealing ring 30 from completely moving out of the connecting hole 21 and losing the effect of covering the gap between the drain pipe 20 and the inner wall of the mounting hole 11, a limiting ring 31 is integrally formed on the inner wall of the sealing ring 30, and a limiting groove 212 is opened on the inner wall of the connecting hole 21 along the diameter direction of the cross section of the drain pipe 20. The limiting ring 31 is inserted into the limiting groove 212 and can move in the limiting groove 212.

[0050] When the sealing ring 30 moves in the connecting hole 21, the limiting ring 31 moves in the limiting groove 212. When the limiting ring 31 abuts against the inner wall of the limiting groove 212 on the side away from the central axis of the drain pipe 20, the limiting ring 31 is restricted from moving in the direction away from the drain pipe 20, that is, the limiting ring 31 cannot be completely pulled out of the connecting hole 21, thereby increasing the stability of the connection between the sealing ring 30 and the drain pipe 20.

[0051] Reference Figure 1 and Figure 3 In order to facilitate the water falling on the blocking ring 30 to enter the drain pipe 20, a push assembly 40 for driving the blocking ring 30 to bulge or sink is provided on the inner wall of the mounting hole 11. The push assembly 40 includes a push pipe 41, a positioning plate 42 and a spring 43. The push pipe 41 is vertically arranged and penetrates from top to bottom. The top of the push pipe 41 is penetrated by the blocking ring 30 and is fixed against the blocking ring 30. The bottom end of the push pipe 41 is connected with a water outlet assembly 60, which enables the push pipe 41 to store a certain amount of water and discharge the water in the push pipe 41 into the drain pipe 20.

[0052] Reference Figure 1 and Figure 3 The positioning plate 42 is located below the blocking ring 30 and is cast and fixed on the inner wall of the mounting hole 11. The push tube 41 passes through the positioning plate 42 and can move vertically on the positioning plate 42. In order to increase the stability of the push tube 41, a mounting plate 50 is provided between the positioning plate 42 and the blocking ring 30. The mounting plate 50 is parallel to the positioning plate 42 and is also cast and fixed on the inner wall of the mounting hole 11. The push tube 41 also passes through the mounting plate 50. When the push tube 41 moves up and down, it is restricted by the positioning plate 42 and the mounting plate 50, so that the push tube 41 always maintains a vertical state, which increases the stability of the movement of the push tube 41. The spring 43 is sleeved on the push tube 41 and is located between the mounting plate 50 and the positioning plate 42. Specifically, one end of the spring 43 is fixed to the push tube 41, and the other end is fixed to the positioning plate 42.

[0053] In the initial state, under the elastic force of the spring 43, the push tube 41 drives the blocking ring 30 to move upward, and the positions of the two sides of the blocking ring 30 are fixed, so that the blocking ring 30 is in a convex state. When water falls on the blocking ring 30, it will move along the top wall of the blocking ring 30 to the low points on both sides of the blocking ring 30, so that the water on the blocking ring 30 slides from the edge of the blocking ring 30 into the drain pipe 20. When the water falls on the blocking ring 30, the water will also enter the pushing tube 41 from the top opening of the pushing tube 41, thereby increasing the weight of the pushing tube 41 itself, and the pushing tube 41 falls, squeezing the spring 43, and driving the blocking ring 30 to move downward until the blocking ring 30 is in a concave state.

[0054] Reference Figure 3 and Figure 4 The water outlet assembly 60 includes a water storage box 61 and a water outlet pipe 62. The water storage box 61 is located below the positioning plate 42 and is connected to the bottom end of the push tube 41. A water outlet hole 611 is provided on the bottom wall of the water storage box 61. A closing assembly 70 for sealing the water outlet is provided in the water storage box 61.

[0055] Reference Figure 3 and Figure 4 A water outlet pipe 62 is connected to the side wall of the drain pipe 20. The water outlet pipe 62 is a hose. One end of the water outlet pipe 62 away from the drain pipe 20 is connected to the positioning plate 42 through a positioning rod 621, and the push tube 41 can drive the water outlet hole 611 on the water storage box 61 to be inserted into the water outlet pipe 62. When a crack occurs between the concrete layer 10 and the drain pipe 20, the water outlet pipe 62 moves with the movement of the positioning plate 42 under the drive of the positioning rod 621, so that the water outlet pipe 62 is always aligned with the water outlet hole 611.

[0056] The water storage box 61 increases the volume of water that the push tube 41 can hold. That is, the weight of the push tube 41 is increased so that the push tube 41 squeezes the spring 43 and drives the blocking ring 30 to move downward until the blocking ring 30 is in a concave state. In this process, the water storage box 61 continues to move downward until the water outlet pipe 62 is inserted into the water outlet hole 611. At this time, the end of the water outlet pipe 62 abuts against the sealing assembly 70, and the weight of the push tube 41 continues to drive the downward movement, so that the water outlet pipe 62 is relatively deep into the water storage box 61, so that the water outlet pipe 62 pushes the sealing assembly 70 until the sealing assembly 70 is in an open state, that is, the water storage box 61 and the water outlet pipe 62 are connected, so that the water in the water storage box 61 can quickly enter the water outlet pipe 62, and then follow the water outlet pipe 62 to reach the drain pipe 20.

[0057] Reference Figure 3 and Figure 4, because the diameter of the water outlet pipe 62 is larger than the diameter of the push tube 41, that is, the rate at which water is discharged from the push tube 41 is greater than the rate at which water enters the push tube 41 from the top of the push tube 41. When the water in the push tube 41 is reduced to the point where the weight of the push tube 41 is insufficient to overcome the elastic force of the spring 43, the spring 43 pushes the push tube 41 upward, and the blocking ring 30 returns to its original raised state. At this time, the water outlet pipe 62 is relatively withdrawn from the water outlet hole 611, and the sealing assembly 70 re-seals the water outlet hole 611, so that the water storage box 61 can store water. When the water storage box 61 and the push tube 41 store more water and become heavier and move downward, the water outlet pipe 62 will be inserted into the water outlet pipe 62 again to extract and release the water in the water storage box 61 and the push tube 41, and the above steps are repeated to achieve continuous up and down fluctuations of the blocking ring 30.

[0058] Reference Figure 1 and Figure 4 The closing assembly 70 includes two closing plates 71, both of which are located in the water storage box 61, and the two closing plates 71 are relatively arranged with the central axis of the water outlet 611 as the axis. The two closing plates 71 are hinged on the inner wall of the water storage box 61 on the sides away from each other and are located at the opening of the water outlet. When the side walls of the two closing plates 71 that are close to each other abut against each other, the water outlet 611 is blocked.

[0059] When the water outlet pipe 62 is inserted into the water outlet hole 611, the end wall of the water outlet pipe 62 abuts against the position where the two closing plates 71 abut against each other, and the water outlet pipe 62 continues to penetrate into the water storage box 61, so that the two closing plates 71 are simultaneously subjected to an upward thrust, so that the two closing plates 71 are gradually separated, thereby causing a gap to appear between the two closing plates 71, and the water outlet hole 611 loses the obstruction of the closing plate 71, so that the water storage box 61 is connected to the water outlet pipe 62 through the water outlet hole 611. At this time, the water in the water storage box 61 and the push tube 41 can flow into the water outlet pipe 62, and reach the drain pipe 20 along the water outlet pipe 62, thereby completing the discharge of water in the water storage box 61 and the push tube 41.

[0060] Reference Figure 1 and Figure 4 When the water outlet pipe 62 is connected to the water storage box 61, in order to prevent water from leaking out from the gap between the water outlet pipe 62 and the inner wall of the water outlet hole 611, a receiving cover 80 is fixed on the water outlet pipe 62. The receiving cover 80 is made of deformable rubber material. The inner diameter of the receiving cover 80 gradually increases toward the end of the water outlet pipe 62 away from the drain pipe 20. When the end of the water outlet pipe 62 is inserted into the water outlet hole 611, the receiving cover 80 abuts against the bottom wall of the water storage box 61. A water inlet hole 622 is opened through the side wall of the water outlet pipe 62, and the water inlet hole 622 is located in the receiving cover 80.

[0061] When the water outlet pipe 62 is inserted into the water outlet hole 611 and pushes the closing plate 71, the water outlet pipe 62 receives the water flowing out from the gap between the two closing plates 71, and the closing plate 71 is gradually separated from the inner wall of the water storage box 61 during rotation, so the water in the water storage box 61 is easy to leak out, and the receiving cover 80 receives the water flowing out from between the water outlet pipe 62 and the inner wall of the water outlet hole 611, and the water in the receiving cover 80 finally enters the water outlet pipe 62 through the water inlet hole 622, so that the water is not easy to enter the concrete outside the drainage pipe 20, that is, the quality of the basement floor will not be affected, and no peeling, bulging or cracking will occur.

[0062] The implementation principle of the anti-leakage structure of the basement waterproofing project in the embodiment of the present application is as follows: when there is water on the basement floor, the water flows into the installation hole 11, part of the water falls on the blocking ring 30, and the other part of the water directly enters the drain pipe 20 from the opening of the drain pipe 20 until it is discharged along the drain pipe 20. In the initial state, the jacking assembly 40 makes the blocking ring 30 in a convex state, that is, the middle of the blocking ring 30 is high and the two sides are low. When the water falls on the blocking ring 30, it will move along the top wall of the blocking ring 30 to the low points on both sides of the blocking ring 30, so that the water on the blocking ring 30 slides from the edge of the blocking ring 30 into the drain pipe 20, and then is discharged from the drain pipe 20, so that the water will not penetrate into the gap between the installation hole 11 and the side wall of the drain pipe 20, but soaked in the concrete, that is, the quality of the basement floor will not be affected, and then there will be no peeling, bulging or cracking.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
