Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-seepage structure technology, and in particular to a civil engineering anti-seepage structure. Background Technology
[0002] In civil engineering, basements, as underground functional spaces, are prone to seepage problems due to their long-term underground environment and exposure to multiple moisture sources, including groundwater, soil pore water, and surface seepage. The seepage risk in basements stems primarily from two aspects: First, when the groundwater level fluctuates, moisture can seep in through weak points such as cracks in the concrete structure, joints between walls and the floor slab, and pipe penetrations. Second, condensation caused by poor ventilation and temperature changes within the basement can accumulate on the walls or floor and easily seep into the interior of the walls along structural gaps, leading to dampness in the base layer. These seepage problems not only cause mold growth on basement walls and dampness on the floor, affecting functionality, but also accelerate the corrosion and carbonization of reinforced concrete structures. Moisture combines with carbon dioxide and chloride ions in the air, damaging the concrete protective layer, causing the reinforcing steel to rust and expand, ultimately leading to structural cracking. This seriously threatens the structural safety and service life of the basement and may even require costly repairs and reinforcement.
[0003] Traditional basement waterproofing solutions primarily focus on "single-point water blocking," commonly involving laying waterproof membranes or coatings on the water-facing side of the basement, or using waterproof concrete to construct walls and floors. However, these solutions have significant limitations in basement scenarios: First, during basement construction, the laying of waterproof membranes is easily affected by the flatness of the substrate and the construction temperature. Improper treatment at the membrane joints can easily create "leakage channels," and under long-term groundwater and soil pressure, the membrane is prone to peeling off from the substrate and aging and damage. Second, improper curing of waterproof concrete can easily lead to shrinkage cracks and cannot cope with structural deformation caused by basement settlement later on; once cracks appear, they become entry points for seepage. Third, traditional solutions lack effective "drainage buffer" designs. Even if a small amount of water seeps in, it cannot be drained in time, easily accumulating inside the structure and gradually destroying the waterproofing system. Especially in areas with high groundwater levels or during the rainy season, the failure rate of traditional solutions increases significantly.
[0004] Therefore, this application provides a civil engineering anti-seepage structure. Utility Model Content
[0005] This utility model provides a civil engineering anti-seepage structure that can solve the water leakage problem in basements that rely solely on laying waterproof membranes or applying waterproof coatings on the water-facing side for anti-seepage.

[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0029] Example
[0030] like Figures 1 to 5 As shown, this application provides a civil engineering seepage-proof structure, including:
[0031] The basement foundation 10 has a protrusion 11 in the middle of its upper surface.
[0032] Waterproof wall 20 is installed on the four sides of the upper surface of the basement foundation 10. By installing waterproof wall 20, lateral seepage water can be directly intercepted when the groundwater level fluctuates. When water attempts to penetrate through the side of the foundation under hydrostatic pressure, waterproof wall 20 can block most of the water with its own waterproof performance, reducing the amount of water seeping into the basement.
[0033] In an optional embodiment, a flow guiding mechanism 21 is fixedly installed on the inner wall of the waterproof wall 20 by anchor bolts. The flow guiding mechanism 21 also includes a ceramic fiber board 22 fixedly installed on the inner wall of the waterproof wall 20. A high-density resin board 23 is fixedly installed on the side of the ceramic fiber board 22 away from the waterproof wall 20. By fixing the flow guiding mechanism 21 on the inner wall of the waterproof wall 20, when external water seeps into the basement through the waterproof wall 20, the ceramic fiber board 22 comes into contact with the water and guides the water to drip from the bottom of the ceramic fiber board 22 under the influence of gravity. By setting the high-density resin board 23 to block the water in the ceramic fiber board 22, water vapor is prevented from entering the basement.
[0034] Drainage ditch 30 is located in the gap between the boss 11 and the waterproof wall 20. A water collection cover 33 is fixedly installed inside the drainage ditch 30. Multiple evenly distributed mesh water inlet holes 35 are provided on the side of the water collection cover 33 near the waterproof wall 20. A water pump 31 is fixedly installed on one side inside the water collection cover 33. A drain pipe 32 is fixedly installed at the output end of the water pump 31.
[0035] After adopting the above technical solution, the water entering the waterproof wall 20 is guided by the ceramic fiber board 22 to fall into the drainage ditch 30, and then enters the water collection hood 33 through the mesh inlet 35 on one side of the water collection hood 33. The water entering the water collection hood 33 is pumped out by the water pump 31, thereby achieving the effect of preventing seepage.
[0036] In an optional embodiment, the top of the water collection cover 33 is covered with a cover plate 34. One side of the cover plate 34 is in contact with the outer wall of the flow guiding mechanism 21, and the other side is in contact with the outer wall of the membrane plate 41. By setting the cover plate 34, the upper end of the water collection cover 33 is protected on the one hand, and the drainage ditch 30 can be quickly cleared by removing the cover plate 34 on the other hand.
[0037] In one alternative implementation, the drainage ditch 30 gradually increases in depth from left to right and from front to back, and the water pump 31 is located at the deepest point of the drainage ditch 30, so that the water entering the drainage ditch 30 quickly gathers and is discharged through the water pump 31.
[0038] In an optional embodiment, both the water collection cover 33 and the cover plate 34 are provided with through holes adapted to the drain pipe 32.
[0039] The inner wall 40 is set on the four sides of the upper surface of the protrusion 11. Setting the inner wall 40 on the upper surface of the protrusion 11 reduces the probability of the inner wall 40 directly contacting the damp area at the bottom of the basement foundation 10, and reduces the risk of leakage at the base of the inner wall 40 due to long-term dampness. On the other hand, the protrusion 11 can serve as a transition structure between the inner wall 40 and the basement foundation 10, making it easier to seal the junction of the protrusion 11 and the inner wall 40, further blocking the path of water seeping upward from the foundation.
[0040] In an optional embodiment, multiple membrane panels 41 are fixedly installed on the inner wall of the inner wall 40 using foam adhesive. The membrane panels 41 have high waterproof performance and can improve the waterproofness of the inner wall 40.
[0041] In one optional embodiment, structural adhesive is applied between the joints of two adjacent double-layer panels 41, and a crack-resistant mesh is attached to the outside of the structural adhesive. On the one hand, the gaps between the fibers of the mesh further intercept trace amounts of water vapor that may penetrate the structural adhesive. On the other hand, it can prevent external friction and collision from directly damaging the structural adhesive sealing layer, forming a dual waterproof system of "structural adhesive sealing + crack-resistant mesh protection", which greatly reduces the risk of water seepage at the joints and complements the waterproof performance of the double-layer panel body.
