Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a waterproof structure for the basement of a high-rise building. Background Technology

[0002] High-rise buildings are residential buildings with a height greater than 27m and non-single-story factories, warehouses, and other civil buildings with a height greater than 24m. To enhance the load-bearing capacity of the foundation of high-rise buildings, basements are often constructed to increase the foundation depth and improve the utilization of the lower space. The waterproofing structure built during the construction of the basement is a structure that blocks the passage of water.

[0003] Currently, some basement waterproofing designs use multiple layers of waterproofing materials to create multi-layered partitions, blocking groundwater from seeping into the basement. While sufficiently thick multi-layered partitions can prevent seepage, over time, groundwater will continue to seep into the partitions, causing the partition structure to slowly deteriorate and reducing its effectiveness in preventing groundwater seepage. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that groundwater will continuously seep into the isolation wall, causing the isolation wall structure to slowly deteriorate, and proposes a waterproof structure for the basement of high-rise buildings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waterproof structure for the basement of a high-rise building includes: a water-retaining wall, wherein a water-collecting cavity is provided inside the water-retaining wall, and water inlet pipes connected to the water-collecting cavity are fixedly installed on both sides of the water-retaining wall; and a water-draining pipe fixedly installed inside the water-retaining wall, wherein the bottom of the water-draining pipe extends into the water-collecting cavity.

[0007] To facilitate the entry of water from the soil layer into the water collection cavity, preferably, multiple sets of water inlet pipes are evenly arranged, and the axes of the multiple sets of water inlet pipes are all inclined.

[0008] To reduce the amount of mud and sand in the soil layer entering the water collection cavity through the water inlet pipe, the water inlet of the water inlet pipe is further designed so that its outlet is lower than its outlet and the outlet is connected to the water collection cavity.

[0009] To further reduce the amount of sediment entering the water collection chamber, preferably, a funnel-shaped interceptor is fixedly installed inside the water inlet pipe.

[0010] Furthermore, the smaller end of the interceptor tube is close to the water inlet of the water inlet pipe.

[0011] Preferably, multiple sets of support plates are fixedly installed inside the water retaining wall, and the two ends of the multiple sets of support plates are respectively fixedly connected to the inner walls of the two sides of the water collection cavity.

[0012] Preferably, the system further includes a pouring layer, which includes a top slab and a bottom slab, with a fixing layer between the top slab and the bottom slab. A water pump is fixedly installed on the top slab, with one end of the water pump connected to a water pumping pipe and the other end of the water pump fixedly installed with a drain pipe.

[0013] Furthermore, a waterproof layer is fixedly installed on the outer wall of both the base plate and the fixing layer, and a fine stone concrete protective layer is fixedly installed on the outer wall of the waterproof layer.

[0014] Compared with the prior art, this utility model provides a waterproof structure for the basement of a high-rise building, which has the following beneficial effects:

[0015] 1. The waterproofing structure of the basement of this high-rise building is achieved by fixing a water retaining wall in front of the fine stone concrete protective layer, with a water collection cavity inside the water retaining wall, and an inlet pipe fixed on the water retaining wall that is connected to the water collection cavity. Most of the water in the soil base layer can enter the water collection cavity through the inlet pipe, which can reduce the erosion of the isolation wall by groundwater, thus reducing its waterproofing effect and affecting its service life. In addition, the installation of a water pumping pipe can periodically pump out the water in the water collection cavity, which helps to improve the waterproofing effect.

[0016] 2. The waterproof structure of the basement of this high-rise building can reduce the amount of mud and sand in the soil layer entering the water collection cavity through the water inlet pipe by setting the water inlet pipe at an angle on the water retaining wall. The accumulation of mud in the water collection cavity will affect its water collection effect. In addition, the funnel-shaped intercepting cylinder is fixedly installed in the water inlet pipe, which can further improve the protective effect.

[0017] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model, by fixing a water retaining wall in front of the fine stone concrete protective layer, allows most of the water in the soil base layer to enter the water collection cavity through the water inlet pipe, which can reduce the erosion of the isolation wall by groundwater, thus reducing its waterproof effect and affecting its service life. In addition, the installation of a water pumping pipe can periodically pump out the water in the water collection cavity, which helps to improve the waterproof effect. Attached Figure Description

[0025] Example:

[0026] Reference Figures 1-4A waterproof structure for the basement of a high-rise building includes a base slab 1, a top slab 101 fixedly mounted on the base slab 1 via a fixing layer 102, and waterproof layers 104 fixedly mounted on the outer walls of the base slab 1 and the fixing layer 102 near the soil base. A fine aggregate concrete protective layer 103 is fixedly mounted on the outer wall of the waterproof layer 104. In use, this structure prevents water from seeping into the basement. The base slab 1, fixing layer 102, waterproof layer 104, and fine aggregate concrete protective layer 103 are collectively referred to as an isolation wall. The top of the water-retaining wall 2 is connected to... The top plate 101 is fixedly connected to the bottom, and a fixing plate is used to fix the water retaining wall 2 to the fine stone concrete protective layer 103 on the side near the water retaining wall 2. A water collection cavity is provided inside the water retaining wall 2. Setting the water retaining wall 2 outside the fixing layer 102 can reduce water penetration into the fine stone concrete protective layer 103. Multiple sets of water inlet pipes 202 are fixedly installed on both sides of the water retaining wall 2. At least two sets of water inlet pipes 202 are provided, preferably twenty sets. The outlets of the multiple sets of water inlet pipes 202 are respectively connected to the water collection cavity. The water cavities are interconnected, and the axes of multiple sets of water inlet pipes 202 are all inclined. The inlet of the water inlet pipe 202 is designed to be lower than its outlet, that is, the end located inside the water collection cavity is the outlet, and the end located on the outer wall of the water retaining wall 2 is the inlet. The angle between the axis of the water inlet pipe 202 and the vertical plane of the water retaining wall 2 is designed to be between 10° and 45°, preferably 30°. In use, the water retaining wall 2 is fixedly installed in front of the fine stone concrete protective layer 103, and a water collection cavity is opened in the water retaining wall 2. A water inlet pipe 202 connected to the water collection cavity is fixedly installed on the wall 2. Most of the water in the soil base can enter the water collection cavity through the water inlet pipe 202, which can reduce the erosion of the isolation wall by groundwater, thus reducing its waterproof effect and affecting its service life. A water pumping pipe 3 is fixedly installed on the top plate 101, with the bottom of the water pumping pipe 3 extending into the water collection cavity. In use, by fixing the water pumping pipe 3 on the top plate 101 and connecting it to the water collection cavity, the water in the water collection cavity can be periodically pumped out through the water pumping pipe 3, thereby improving the waterproof effect.

[0027] In use, a water-retaining wall 2 is fixedly installed in front of the fine stone concrete protective layer 103. A water collection cavity is opened inside the water-retaining wall 2, and an inlet pipe 202 connected to the water collection cavity is fixedly installed on the water-retaining wall 2. Most of the water in the soil base can enter the water collection cavity through the inlet pipe 202, which can reduce the erosion of the isolation wall by groundwater, thus reducing its waterproof effect and affecting its service life. In addition, the installation of the pumping pipe 3 can periodically pump out the water in the water collection cavity, which helps to improve the waterproof effect. By setting the inlet pipe 202 at an angle on the water-retaining wall 2, the amount of mud and sand in the soil base can be reduced from entering the water collection cavity through the inlet pipe 202. The accumulation of mud in the water collection cavity affects its water collection effect. In addition, a funnel-shaped intercepting cylinder 203 is fixedly installed inside the inlet pipe 202, which can further improve the protective effect.

[0028] Reference Figure 4 A funnel-shaped interceptor 203 is fixedly installed inside the water inlet pipe 202. The small end of the interceptor 203 is designed to be close to the water inlet of the water inlet pipe 202. During use, this reduces the amount of mud entering the water collection chamber through the water inlet pipe 202, which helps to reduce the frequency of cleaning the water collection chamber and improve the usage effect.

[0029] Reference Figure 1 and Figure 3 Multiple sets of support plates 201 are fixedly installed inside the water retaining wall 2. At least two sets of support plates 201 are provided, preferably ten sets. The two ends of the ten sets of support plates 201 are fixedly connected to the inner walls of both sides of the water collection cavity. In use, by fixing the support plates 201 inside the water collection cavity, the strength of the water retaining wall 2 can be improved, preventing the water retaining wall 2 from collapsing into the water collection cavity and improving its service life.

[0030] Reference Figure 2 A water pump is fixedly installed on the top plate 101. One end of the water pump is connected to the water pumping pipe 3, and a drain pipe is fixedly installed at the other end of the water pump. When in use, by starting the water pump, the water in the water collection chamber can be pumped out through the water pumping pipe 3, which helps to reduce the moisture in the soil layer around the retaining wall 2, thereby reducing the infiltration of groundwater into the isolation wall and helping to improve the service life of the isolation wall.
