Abstract
Description
Technical Field
[0001] This utility model belongs to the field of basement waterproofing and relates to a basement anti-seepage wall structure. Background Technology
[0002] Basement construction can fully utilize space, save land resources, and increase economic benefits, while also effectively optimizing the living experience as a building accessory. However, basements are generally damp, prone to dampness, leaks, and water accumulation. Therefore, waterproofing design is paramount in basement design, directly impacting its usability after completion. Once leaks occur, repairs are difficult and often ineffective. Currently, basement waterproofing primarily relies on proper compaction during pouring to minimize gaps and openings, ensuring overall airtightness, supplemented by waterproof coatings. However, due to the limitations of construction quality and the long-term contact with groundwater, water can still seep in. To address basement leakage, we propose a basement waterproofing wall structure that actively drains potential seepage or water accumulation, ensuring a dry basement surface and preventing further water damage. Utility Model Content
[0003] The purpose of this utility model is to provide a basement anti-seepage wall structure that uses a protective layer to isolate water seepage and utilizes its own density and high hardness to prevent ordinary impacts from penetrating the wall and causing the protection to fail. A moisture-proof coating layer is set to prevent dampness, which basically eliminates obvious water stains and damp conditions in the basement. Furthermore, drainage capillaries are arranged at an angle in the permeable layer so that seepage is blocked by the protective layer and then guided out by the drainage capillaries to prevent greater damage.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A basement anti-seepage wall structure includes a cement base layer, a permeable layer, a protective layer, and a moisture-proof coating layer arranged in sequence. The moisture-proof coating layer is located on the inner surface of the basement. Drainage capillary tubes are installed in the permeable layer. The drainage capillary tubes are installed close to the cement base layer and inclined to one side. The lower side of each drainage capillary tube is connected to a drainage pipe. The lower end of the drainage pipe is buried in the soil at the bottom of the basement.
[0006] Furthermore, the protective layer is made of rare earth protective material, and its construction thickness is required to be greater than 2mm.
[0007] Furthermore, the permeable layer is constructed by nailing prefabricated permeable panels onto a cement base layer, and the drainage capillary tubes are installed close to the cement base layer. A clearance groove for the capillary tubes is provided on the permeable panels.
[0008] Furthermore, the permeable layer is made of permeable concrete poured on site. After the position of the drainage capillary is fixed, the permeable concrete is coated, and the solidification of the permeable concrete fixes the drainage capillary.
[0009] Furthermore, the drainage capillaries are arranged in 2-3 layers side by side.
[0010] Furthermore, the upper part of the drainage capillary has water-permeable capillary pores for water to seep into the drainage capillary, and the lower part is a closed surface for drainage.
[0011] Furthermore, the angular proportion of the closed surface is 120°-200°.
[0012] Furthermore, the thickness of the permeable layer is 5-8 mm.
[0013] Furthermore, the upper end of the drain pipe is closed, and the lower end extends more than 1m into the ground and its vicinity is filled with sand and gravel to prevent blockage.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0015] 1. A protective layer is constructed on the inner surface of the basement using rare earth protective materials, and then a moisture-proof coating is applied to the outer surface. The protective layer isolates water seepage and, with its density and high hardness, prevents ordinary impacts from penetrating the wall and causing the protection to fail. The moisture-proof coating prevents dampness from returning, essentially eliminating obvious water stains and damp conditions in the basement.
[0016] 2. In this utility model, a permeable layer is provided, and drainage capillaries are arranged at an angle in the permeable layer, so that any possible seepage is blocked by the protective layer and then guided out by the drainage capillaries. By using uniform vertical arrangement and inclined arrangement, tiered drainage can be achieved. Slight seepage in a certain place will not spread over a large area and can be discharged by the capillaries near the seepage point, preventing greater damage.
[0017] 3. The drain capillary tube has capillary holes at the top, which does not obstruct the entry of water. The water collects at the bottom of the drain capillary tube and can be discharged in a timely manner. Attached Figure Description

[0027] Example 1
[0028] This utility model provides a basement anti-seepage wall structure, comprising a cement base layer 1, a permeable layer 2, a protective layer 3, and a moisture-proof coating layer 4 arranged sequentially. The moisture-proof coating layer 4 is located on the inner surface of the basement. A drainage capillary 5 is installed in the permeable layer 2. The drainage capillary 5 is installed close to the cement base layer 1 and inclined to one side. The angle of inclination is generally set between 15° and 30°, taking into account factors such as the dryness of the basement and the span of the wall. Of course, the angle of inclination can be further increased if necessary. The drainage capillary 5 is lower than... Both sides are connected to the drainage pipe 6. The lower end of the drainage pipe 6 is buried in the soil at the bottom of the basement. The drainage pipe 6 is used to collect the seepage water collected in the drainage capillary 5 and guide it into the ground, so that the outermost wall of the basement remains dry. A protective layer 3 is formed on the inner surface of the basement using rare earth protective material, and then a moisture-proof coating layer 4 is coated on the outer surface. The protective layer 3 is used to isolate water seepage, and its own density and high hardness characteristics prevent ordinary collisions from penetrating the wall and causing the protection to fail. The moisture-proof coating layer 4 is set to prevent dampness, basically eliminating obvious water stains and damp conditions in the basement.
[0029] The protective layer 3 is made of rare earth protective material, and its construction thickness is required to be greater than 2mm. The rare earth protective material is a multifunctional rare earth protective material.
[0030] The permeable layer 2 is made by nailing prefabricated permeable panels onto the cement base layer 1. The drainage capillary tubes 5 are installed close to the cement base layer 1. There are clearance grooves for the capillary tubes on the permeable panels. Of course, this is just a more convenient installation method. It is generally suitable for situations where only one layer of drainage capillary tubes 5 is installed close to the cement base layer 1. The slope of the groove needs to match the layout of the drainage capillary tubes 5. In this case, the permeable layer 2 can be set relatively thin, about 3mm.
[0031] The upper part of the drainage capillary tube 5 has water-permeable capillary pores 7 for water to seep into the drainage capillary tube 5, and the lower part is a closed surface for drainage, which can not obstruct the entry of water. The water collects at the lower part of the drainage capillary tube 5 and can be discharged in time. The capillary pores 7 need to be prevented from being blocked during installation.
[0032] The occupancy angle of the closed surface is 120°-200°. Generally, it is required that the area occupied by the water-permeable capillary pores 7 on the upper part of the drainage capillary 5 is larger, or preferably evenly divided.
[0033] The upper end of the drainage pipe 6 is closed, and the lower end extends into the ground soil at least 9 meters deep. The area around it is filled with sand and gravel 8 to prevent blockage. The sand and gravel can be poured in after drilling holes, without digging up the ground. The upper end of the drainage pipe 6 is closed to prevent backflow of water from the upper part, such as blockage of the lower outlet. It is best to use a transparent pipe or set up an observation window to detect blockages in the lower part in time.
[0034] Example 2
[0035] Based on Example 1, the permeable layer 2 can be made by coating with permeable concrete or similar materials on site. For example, if the permeable layer 2 is made by casting permeable concrete on site, the permeable concrete is coated after the position of the drainage capillary 5 is fixed. The permeable concrete solidifies and fixes the drainage capillary 5. Because it is cast on site, multiple layers of drainage capillary 5 can be arranged in parallel to improve the drainage capacity. For example, 2-3 layers of drainage capillary 5 can be arranged in parallel. Because the number of drainage capillary 5 layers increases, the thickness of the permeable layer 2 is 5-8mm to ensure that the permeable layer 2 covers the capillary. In order to achieve a good drainage effect, the capillary drainage pipe 6 is set close to the cement base layer 1 and the protective layer 3. At this time, water seepage or condensation occurs on the two surfaces and can be discharged in time.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions and improvements made by those skilled in the art within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
