Description

Technical Field

[0001] The present application belongs to the technical field of construction engineering, and in particular relates to an anti-seepage structure for basement floors. Background Art

[0002] Water leakage is one of the common problems in basements. It often affects the effective use of basements and even the safety of buildings. It accounts for more than 95% of water leakage projects, and almost all basement water leakage projects have this problem. The most fundamental cause of basement water leakage is cracks in the basement floor. There are many reasons for the cracks in the basement floor, such as on-site maintenance conditions, improper construction methods, differences in concrete construction quality, temperature, shrinkage, etc., which can all cause cracks in the floor. Therefore, it is difficult to completely avoid the occurrence of cracks in the floor in actual projects. However, the appearance of cracks will affect the use function of the basement, and in severe cases, it cannot be used normally.

[0003] The existing Chinese patent with publication number CN107313466B discloses an anti-seepage structure and construction method for a basement floor, including a cushion layer, a basement floor and a reinforced concrete surface layer stacked in sequence from bottom to top, a water conveyance plate is laid between the basement floor and the reinforced concrete surface layer, and a plurality of interconnected drainage channels are opened on the reinforced concrete surface layer; the shock absorbing device and the bottom of the connecting groove are connected and connected to the water conveyance plate through a U-shaped groove, and the water conveyance plate is collected into the drainage channel through a pipe.

[0004] Although the above-mentioned anti-seepage structure is easy to form the guidance and drainage of water flow, the basement is relatively spacious and water seepage may occur anywhere, so improvements are made to this. Summary of the invention

[0005] The purpose of this application is to provide an anti-seepage structure for basement floors in order to solve the above-mentioned technical problems, which can ensure the effect and quality of basement anti-seepage and drainage.

[0006] The present application provides an anti-seepage structure for basement floor, comprising:

[0007] A reinforced concrete structural layer with concrete side walls around it;

[0008] Drainage network, including longitudinal drainage channels and transverse drainage channels;

[0009] The water-absorbing layer is placed above the drainage net;

[0010] The first waterproof layer is placed above the drainage net;

[0011] A concrete surface layer is placed above the first waterproof layer;

[0012] The longitudinal drainage channel and the transverse drainage channel are interconnected, the reinforced concrete structure layer is provided with a drainage ditch adjacent to the concrete side wall, and the first waterproof layer extends upward along the concrete side wall.

[0013] When groundwater seeps upward along the cracks, it is collected by the drainage network and guided to the drainage ditch, reducing the impact of water accumulation on the basement floor. The drainage network is staggered by longitudinal drainage channels and transverse drainage channels, which can fully collect underground seepage water. The water absorption layer further increases the collection of seepage water into the drainage network, thereby improving the water collection efficiency. The first waterproof layer improves the anti-seepage performance of the basement. The first waterproof layer adopts waterproof membrane or asphalt waterproof coating. The concrete surface layer is filled and spread on the first waterproof layer. The first waterproof layer extends upward along the concrete side wall to improve the anti-seepage performance between the concrete side wall and the concrete surface layer. The water absorption layer is placed below the first waterproof layer.

[0014] Furthermore, the longitudinal drainage channel and the transverse drainage channel are provided with a second waterproof layer.

[0015] The second waterproof layer is used to improve the collection efficiency of seepage water and prevent water from seeping out again. The second waterproof layer adopts waterproof membrane, cement mortar waterproof layer or asphalt waterproof coating, etc. The cross-sections of the longitudinal drainage channel and the transverse drainage channel are fan-shaped, trapezoidal or triangular, etc.

[0016] Furthermore, the water absorbing layer is in strip shape and parallel to the longitudinal drainage channel or the transverse drainage channel.

[0017] When the water-absorbing layer is parallel to the longitudinal drainage channel, the water absorbed by the water-absorbing layer flows out into the transverse drainage channel. When the water-absorbing layer is parallel to the transverse drainage channel, the water absorbed by the water-absorbing layer flows out into the longitudinal drainage channel. The water-absorbing layer is made of water-absorbing materials such as sponge or porous bricks, and the absorbed water droplets fall into the drainage net.

[0018] Furthermore, a third waterproof layer is provided on the inner wall surface of the drainage ditch, and the third waterproof layer is connected to the first waterproof layer.

[0019] A third drainage net is set on the inner wall of the drainage ditch to improve the anti-seepage performance between the reinforced concrete structure layer and the concrete side wall, prevent the collected water from seeping downward again, and ensure the collection efficiency of the seepage water.

[0020] Furthermore, it also includes:

[0021] Load-bearing columns, penetrating through the concrete surface layer;

[0022] Circular drainage channel, adjacent to the load-bearing columns;

[0023] Wherein, the first waterproof layer extends upward along the load-bearing column, the annular drainage channel is connected to the drainage net, and the second waterproof layer is placed in the annular drainage channel.

[0024] Load-bearing columns are cast on the basement floor, and the first waterproof layer extends upward along the load-bearing columns to improve the anti-water seepage performance between the concrete surface layer and the load-bearing columns. When water seepage occurs between the reinforced concrete structure layer and the load-bearing columns, it is collected and guided to the drainage network through the annular drainage channel. The second waterproof layer is also placed on the annular drainage channel, and the shape of the annular drainage channel corresponds to the load-bearing columns.

[0025] Furthermore, a U-shaped channel is provided between the annular drainage channel and the drainage net, the height of the annular drainage channel is higher than the height of the drainage net, and the second waterproof layer is placed in the U-shaped channel.

[0026] The U-shaped channel can prevent water collected by the drainage net from flowing into the annular drainage channel. The height of the annular drainage channel is higher than the height of the drainage net, which facilitates the water in the annular drainage channel to flow into the U-shaped channel.

[0027] The beneficial effects of this application are:

[0028] 1. Collect and guide the water into the drainage ditch through the drainage network to reduce the impact of water accumulation on the basement floor. The drainage network can fully collect underground seepage water through the interlaced longitudinal drainage channels and transverse drainage channels.

[0029] 2. The water absorption layer is used to further increase the collection of seepage water into the drainage network, thereby improving the water collection efficiency. The first waterproof layer is used to improve the anti-seepage performance of the basement. The first waterproof layer extends upward along the concrete side wall to improve the anti-seepage performance between the concrete side wall and the concrete surface layer.

[0030] 3. Improve the collection efficiency of seepage water through the second waterproof layer to prevent water from seeping out again. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] When groundwater seeps upward along the cracks, it is collected by the drainage net 200 and guided to the drainage ditch 120, thereby reducing the impact of water accumulation on the basement floor. The drainage net 200 is staggered with the longitudinal drainage channel 210 and the transverse drainage channel 220, so as to fully collect underground seepage water.
