Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology, specifically a drainage structure for walls. Background Technology

[0002] In recent years, the backfill soil for most building exterior walls has been filled with construction waste, which leads to a large amount of water seeping out of the walls during rainy weather, producing pressurized water that damages the wall surface. In addition, a lot of water tends to accumulate at the corners of the walls, causing water seepage over time. The most common solution to this problem is to waterproof the wall surface. However, waterproofing materials have limited waterproofing time and are prone to aging, making them unable to provide a truly long-term solution. In view of the above-mentioned problems, this technical solution designs a drainage structure for walls from the perspective of drainage. Utility Model Content

[0003] The purpose of this utility model is to provide a drainage structure for walls to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A drainage structure for a wall includes a triangular drainage body poured at the root of the outer wall. The triangular drainage body is placed in the backfill area outside the wall to reduce the squeezing thrust of the soil in the backfill area on the root of the outer wall, while preventing rainwater inside the backfill area from seeping into the wall. The bottom of the wall is connected to the foundation poured in the foundation soil area, thus forming a complete wall structure. The triangular waterproofing structure is made of the same material as the wall, and its vertical cross-section is set as a right triangle. Its long right-angled face is cast and connected to the side wall of the wall, and a waterproof coating layer is set on the cast-in connection surface to increase the waterproof performance of the wall. The short right-angled face at the bottom of the triangular waterproofing structure is set with a stepped water-retaining reinforcement plate along the direction perpendicular to the outer wall of the wall. The stepped water-retaining reinforcement plate is inserted into the soil inside the foundation soil area. It is used to gradually deepen the blocking of some rainwater in the backfill soil area and the foundation soil area, that is, to reduce the amount of water transferred towards the lower side of the wall root. At the same time, the connection between the stepped water-retaining reinforcement plate and the soil increases the overall stability of the triangular waterproofing structure. The triangular waterproofing structure has multiple water-guiding channels spaced parallel to its inclined surface. The bottom of each channel connects to a transfer chamber located at the bottom of the triangular waterproofing structure. The side of the triangular waterproofing structure facing the wall is connected to a drainage pipe, which runs along the length of the wall base. Waterproof layers are installed in the triangular waterproofing structures on both sides of the water-guiding channels. When rainwater from the backfill area seeps into the triangular waterproofing structure, it must pass through multiple waterproof layers until it reaches the innermost water-guiding channel. At this point, the amount of rainwater is significantly reduced due to the multiple barriers. Then, by gravity, the rainwater in each channel falls into the transfer chamber and is transferred to the drainage pipe. The drainage pipes between adjacent triangular waterproofing structures are interconnected. The ends of the drainage pipes that are discharged externally are connected to the external drainage structure via valves. The bottom wall of the transfer chamber is designed to slope towards the guide drain pipe, which ensures that rainwater transferred into the transfer chamber can be quickly and automatically transferred into the guide drain pipe. At the same time, the bottom of the transfer chamber is connected to the upper part of the guide drain pipe to prevent rainwater from flowing back into the guide drain pipe.

[0005] Compared with the prior art, the beneficial effects of this utility model are: by using the multi-layer waterproofing layer of the triangular waterproofing body and the stepped water-blocking reinforcement plate to block rainwater infiltration in a stepped manner, the amount of water accumulating in the backfill area migrates to the wall.

[0006] An active drainage path is formed by the water guiding channel and the drainage pipe to avoid water accumulation in the corners of the walls.

[0007] By inserting stepped water-retaining reinforcement plates into the foundation soil area, the compressive strength of the triangular water-conducting body is enhanced, preventing structural deformation caused by backfill soil pressure.

[0008] The waterproof coating layer uses a penetrating crystalline material to block the pores in the concrete, and the waterproof layer uses a corrosion-resistant membrane covered with an epoxy resin coating to extend its service life. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-4 A drainage structure for a wall includes a triangular drainage body 14 cast at the root of the outer wall of the wall 10. The triangular drainage body 14 is placed in the backfill area 12 outside the wall to reduce the squeezing thrust of the soil in the backfill area 12 on the root of the outer wall of the wall 10, and at the same time prevent rainwater inside the backfill area 12 from seeping into the wall 10. The bottom of the wall 10 is connected to the foundation 11 cast in the foundation soil area 13, thus forming a complete wall structure. The triangular waterproofing body 14 is made of the same material as the wall 10. Its vertical cross-section is set as a right triangle. Its long right-angled face is cast and connected to the side wall of the wall 10. The cast and connected surface is provided with a waterproof coating layer 22 to increase the waterproof performance of the wall 10. The short right-angled face at the bottom of the triangular waterproofing body 14 is provided with a stepped water-blocking reinforcement plate 15 along the direction perpendicular to the outer wall of the wall 10. The stepped water-blocking reinforcement plate 15 is inserted into the soil inside the foundation soil area 13. It is used to gradually deepen the blocking of some rainwater inside the backfill soil area 12 and the foundation soil area 13, that is, to reduce the amount of water transferred towards the lower side of the root of the wall 10. At the same time, the connection between the stepped water-blocking reinforcement plate 15 and the soil increases the overall stability of the triangular waterproofing body 14. The triangular waterproofing structure 14 has multiple water-guiding channels 20 spaced parallel to its inclined surface. The bottom of each water-guiding channel 20 connects downwards to a transfer chamber 18 located at the bottom of the triangular waterproofing structure 14. A drainage pipe 17 connects to the side of the triangular waterproofing structure 14 facing the wall 10. The drainage pipe 17 is distributed along the length of the base of the wall 10. Waterproof layers 19 are installed inside the triangular waterproofing structures 14 on both sides of the water-guiding channels 20, allowing rainwater from the external backfill area 12 to flow towards the waterproofing layer. When water seeps into the triangular water-conducting body 14, it needs to pass through multiple layers of waterproof layers 19 to block it until it seeps into the waterproof layer 19 of the innermost water-conducting channel 20. At this time, after multiple blocks, the amount of rainwater will be greatly reduced. Then, by gravity, the rainwater inside each water-conducting channel 20 will fall into the transfer chamber 18 and then be transferred to the drainage pipe 17. The drainage pipes 17 between adjacent triangular water-conducting bodies 14 are interconnected. The end of the drainage pipe 17 placed outside is connected to the external drainage structure through the pipe valve 16. The bottom wall of the transfer chamber 18 is provided with a structure that is inclined towards the guide drain pipe 17, which ensures that the rainwater transferred into the transfer chamber 18 can be quickly and automatically transferred into the guide drain pipe 17. At the same time, the bottom end of the transfer chamber 18 is connected to the upper side of the guide drain pipe 17, which prevents the rainwater in the guide drain pipe 17 from flowing back. The drainage structure can be equipped with a pump or other drive source to increase the discharge of rainwater from the drainage pipe 17. At the same time, the external drainage structure should be lower than the height of the drainage pipe 17 to prevent it from affecting the automatic and normal discharge of rainwater from the drainage pipe 17.

[0019] In this embodiment of the invention, the waterproof coating layer 22 is made of a penetrating crystalline waterproof material. When the triangular waterproof body 14 and the outer wall of the wall 10 are poured, the material is mixed into the pouring material through a chemical reaction, thereby blocking the concrete pores at the pouring point of the triangular waterproof body 14 and the wall 10, thus increasing the impermeability. The waterproof layer 19 is made of roll material. When processing the water channel 20, the channel is designed in advance, and then the roll material is laid in the inner wall of the water channel 20 to form a waterproof layer. Then the control inlet of the water channel 20 is sealed. The roll material is generally: SBS / APP modified bitumen waterproof roll, polymer waterproof roll, self-adhesive waterproof roll, etc. Among them, the outermost wall of the triangular water channel 14 that contacts the backfill area 12 is directly coated with epoxy resin coating, which has high strength and chemical corrosion resistance, so that it can still maintain good waterproof performance when it comes into contact with garbage and liquid in the backfill soil in the backfill area 12. Specifically, the stepped water-retaining reinforcement plate 15 and the triangular water-conducting body 14 are made of the same material. The inner surface of the transfer chamber 18 and the outer surface of the stepped water-retaining reinforcement plate 15 are both provided with a waterproof layer 19, which is used to perform waterproofing function and fully transfer the infiltrated water. That is, the outer surface of the stepped water-retaining reinforcement plate 15 is covered with a waterproof layer 19, and the plate is stepped to disperse soil pressure.

[0020] The working principle of this utility model is as follows: Rainwater blocking stage: When rainwater in the backfill area 12 comes into contact with the triangular waterproofing body 14, the epoxy resin coating on its outer surface blocks the initial penetration. As residual moisture migrates inward, it is gradually intercepted by the multi-layered waterproof layers 19 on both sides of the water channel 20.

[0021] Rainwater collection stage: Rainwater seeping into the water channel 20 flows into the transfer chamber 18 by gravity along the slope; The inclined design of the inner bottom wall of the transfer chamber 18 allows the accumulated water to automatically flow into the drainage pipe 17. That is, the inner bottom wall of the transfer chamber 18 is an inclined surface that slopes towards the drainage pipe 17, and the inlet of the drainage pipe 17 is located on the upper side of the bottom end of the transfer chamber 18.

[0022] Active drainage stage: The drainage pipe 17 transports the accumulated water to the external drainage system, which may include a pump body and the pipe valve 16 controls the discharge; A stepped water-retaining reinforcement plate 15 is inserted into the foundation soil area 13 to prevent soil moisture from seeping down to the base of the wall.

[0023] Corrosion prevention and reinforcement mechanism: The waterproof coating layer 22 forms an anti-seepage barrier at the casting interface, and the waterproof layer 19 on the surface of the stepped water-retaining reinforcement plate 15 prevents corrosion.

[0024] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0025] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
