Description

Technical Field

[0001] This utility model relates to the field of basement waterproofing technology, and in particular to a waterproofing structure for basement roof slabs. Background Technology

[0002] With economic development and accelerated urbanization, the utilization rate of urban underground space is constantly increasing, and the construction of underground spaces is becoming more and more widespread. Urban basements are becoming larger and deeper, a result of the increasing size and height of urban buildings and the full utilization of basement space. However, the enclosure structure of basements is frequently subjected to erosion from various types of water. To ensure a good usage environment, conditions, and lifespan for basements, proper waterproofing design is essential.

[0003] For example, a waterproof structure for basement roof slabs with authorization announcement number CN207739293U achieves organized drainage with zero slope, eliminating the need for a slope-finding layer, protective layer, and isolation layer, replacing the traditional drainage filter layer, collecting infiltrated water for use as garden irrigation water, saving water resources, facilitating construction, shortening the construction period, saving costs, facilitating maintenance, and reducing blockages.

[0004] However, there are still some problems with the use of the above-mentioned basement roof waterproofing structure. For example, the basement roof waterproofing structure generally uses asphalt waterproof membrane as the waterproofing structure. Asphalt membrane has a good waterproofing effect, but a subbase and road soil layer are laid on top of the waterproof membrane. The subbase and soil layer will allow rainwater and water to seep down. If the seeping rainwater cannot drain in time, it will temporarily accumulate on top of the waterproof membrane. The waterproof membrane will be soaked in water for a long time, which will greatly reduce the waterproofing effect and affect the service life of the basement roof waterproofing structure. Summary of the Invention

[0005] This utility model aims to solve the problems existing in the prior art by providing a waterproof structure for basement roofs, which can achieve rapid evaporation and drainage to reduce rainwater accumulation and improve the service life of the basement roof by adding an extra waterproof structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] Design a waterproof structure for basement roof slab, including basement roof slab, surface soil layer and vegetation layer, wherein the vegetation layer is fixedly laid on top of the surface soil layer, and an evaporation interception and evaporation acceleration drainage structure is provided above the surface soil layer, and an additional waterproof structure is provided on the inner side of the basement roof slab below the basement roof slab.

[0008] In a further improvement, the intercepting evaporation accelerated drainage structure includes a cushion layer and a water-absorbing trough. Multiple water-absorbing troughs are fixedly arranged inside the surface soil layer. An evaporation port is fixedly opened at the top of the water-absorbing trough. A gravel layer is fixedly laid below the surface soil layer. An intercepting layer is fixedly installed at the lower end of the gravel layer. The cushion layer is fixedly connected to the lower end of the intercepting layer.

[0009] To further improve the design, a waterproof structure including water-stop bolts and embedded parts is added to the inner side of the top slab. Multiple embedded parts are fixedly installed inside the basement top slab, and multiple water-stop bolts are threadedly connected to the bottom of the basement top slab. Support blocks are fixedly connected to the inner side of the multiple water-stop bolts, and a waterproof coating is fixedly installed on the top of the multiple support blocks.

[0010] To further improve the design, the inner wall of the waterproof coating is fitted tightly against the lower end of the basement roof slab, and the top ends of the plurality of water-stop bolts are threadedly connected to the lower end of the embedded parts.

[0011] To further improve the design, a cold-applied primer layer is fixedly installed above the basement roof slab, and a waterproof membrane layer is fixedly laid on top of the cold-applied primer layer.

[0012] Further improvements include the upper part of the waterproof membrane layer being movably connected to the lower end of the padding layer.

[0013] The beneficial effects of this utility model are as follows: After rainwater falls, some of it seeps into the surface soil layer and then downwards, while some is absorbed by the clay inside the water absorption channel and does not seep down. In this way, the water absorption channel locks in some of the rainwater, allowing it to evaporate naturally through the sunken evaporation outlet on sunny days. The interception layer is made of polyethylene-polypropylene composite roll material, bonded with cement adhesive, which is inexpensive and can serve as the first layer of waterproofing structure for basements. Rainwater is intercepted and retained on top by the composite roll material of the interception layer, facilitating its flow and evaporation. Rainwater rarely accumulates on top of the waterproof roll material for extended periods, protecting the waterproofing structure tightly attached to the basement ceiling and extending its service life.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Example:

[0023] See attached document Figure 1-6 In this embodiment, a waterproof structure for a basement roof includes a basement roof slab 1, a surface soil layer 2, and a vegetation layer 3. The vegetation layer 3 is fixedly laid on top of the surface soil layer 2. The surface soil layer 2 is mainly composed of sandy soil or loam, which provides good drainage and air permeability. Woody plants or landscape plants with root systems that can lock in the soil can be planted on top of the surface soil layer 2. An evaporation-intercepting and drainage-accelerating structure 4 is provided above the surface soil layer 2. A waterproof structure 5 is added to the inner side of the basement roof slab below the basement roof slab 1.

[0024] The intercepting evaporation-accelerated drainage structure 4 includes a cushion layer 41 and water-absorbing channels 44. Multiple water-absorbing channels 44 are fixedly arranged inside the surface soil layer 2. The water-absorbing channels 44 are made of clay soil. Clay soil particles are very fine and have a large specific surface area, providing more adsorption sites to bind water molecules. This allows water molecules to be tightly adsorbed onto the surface of soil particles and into pores. When rainwater falls, some seeps down along the surface soil layer 2, while some is absorbed by the clay soil inside the water-absorbing channels 44 and does not seep down. In this way, the water-absorbing channels 44 lock in some rainwater, allowing it to evaporate naturally through the sunken evaporation outlets 45 excavated above on sunny days. An evaporation port 45 is fixedly opened at the top of the surface soil layer 2. A gravel layer 43 is fixedly laid below the surface soil layer 2. An interception layer 42 is fixedly installed at the lower end of the gravel layer 43. The gravel layer 43 creates conditions for laying the surface soil layer 2. The interception layer 42 is a polyethylene polypropylene composite roll material, which is bonded with cement adhesive. It is inexpensive and can serve as the first waterproof structure of the basement. In this way, rainwater will be intercepted by the composite roll material of the interception layer 42 and left above, which facilitates drainage and evaporation. The cushion layer 41 is fixedly connected to the lower end of the interception layer 42. The cushion layer 41 is made of inorganic binder stabilized granular material that isolates the interception layer 42 from the waterproof roll material layer 62 below. It has good stability and strong compressive strength.

[0025] A waterproof structure 5 is added to the inner side of the top slab, including water-stop bolts 51 and embedded parts 54. Multiple embedded parts 54 are fixedly installed inside the basement top slab 1. The embedded parts 54 are multiple metal steel embedded structures placed inside the concrete basement top slab 1. A relatively thin waterproof coating 53 is then laid on the inner side of the basement top slab 1. The waterproof coating 53 is made of JS polymer cement-based coating. With the help of multiple water-stop bolts 51, the support blocks 52 are driven into the interior of the basement top slab 1. The connection position of the waterproof coating 53 is supported and pushed by the support blocks 52 to maintain continuity and prevent it from falling off. Multiple water-stop bolts 51 are threadedly connected to the bottom of the basement top slab 1. The support blocks 52 are fixedly connected to the inner side of the multiple water-stop bolts 51. The waterproof coating 53 is fixedly installed on the top of the multiple support blocks 52. The inner wall of the waterproof coating 53 is tightly abutted against the lower end of the basement top slab 1. The top of the multiple water-stop bolts 51 is threadedly connected to the lower end of the embedded parts 54.

[0026] A cold primer layer 61 is fixedly installed above the basement roof slab 1. The cold primer is a liquid coating made by diluting and dissolving asphalt in solvents such as kerosene, light diesel oil or gasoline. It is used as the base layer for waterproofing projects at room temperature. A waterproof membrane layer 62 is fixedly laid on top of the cold primer layer 61. The waterproof membrane layer 62 is made of SBS modified bitumen waterproof membrane. Multiple rolls of waterproof membrane layer 62 overlap by more than 20 cm and are neatly laid on top of the basement roof slab 1 to form a second waterproof structure. The top of the waterproof membrane layer 62 is movably connected to the bottom of the padding layer 41.

[0027] Working principle:

[0028] A waterproof structure for the basement roof can be installed on the upper layer of the basement roof to accelerate drainage, intercept rainwater, and prevent water seepage, thereby reducing the occurrence of basement leaks.

[0029] The water absorption trough 44 is made of clay soil. Clay soil particles are very fine and have a large specific surface area, providing more adsorption sites to bind water molecules. This allows water molecules to be tightly adsorbed onto the surface and pores of the soil particles. When rainwater falls, some seeps down along the topsoil layer 2, while the rest is absorbed by the clay soil inside the water absorption trough 44 and does not seep down. In this way, the water absorption trough 44 locks in some rainwater, allowing it to evaporate naturally through the sunken evaporation outlet 45 on sunny days. The gravel layer 43 creates conditions for laying the topsoil layer 2, and the interception layer... 42 is a polyethylene-polypropylene composite roll material, which is bonded with cement adhesive. It is inexpensive and can be used as the first layer of waterproofing structure in the basement. Rainwater will be intercepted and trapped above by the composite roll material of the interception layer 42, which facilitates drainage and evaporation. The pad layer 41 is fixedly connected to the lower end of the interception layer 42. The pad layer 41 is made of inorganic binder stabilized granules that isolate the interception layer 42 from the waterproof roll material layer 62 below. It has good stability and strong compressive strength. Rainwater can rarely accumulate on the waterproof roll material for a long time, protecting the waterproof structure above the basement roof slab and extending its service life.

[0030] Cold primer is a liquid coating made by diluting and dissolving asphalt in solvents such as kerosene, light diesel oil or gasoline. It is used as the base layer of waterproofing projects at room temperature. The waterproof membrane layer 62 is made of SBS modified bitumen waterproof membrane. Multiple rolls of waterproof membrane layer 62 overlap by more than 20 cm and are neatly laid on top of the basement roof slab 1 to form a second waterproof structure.

[0031] The embedded parts 54 are multiple metal steel embedded structures placed inside the concrete basement roof slab 1. A thin waterproof coating 53 is then laid on the inner side of the basement roof slab 1. The waterproof coating 53 is made of JS polymer cement-based coating. With the help of multiple water-stop bolts 51, the support blocks 52 are driven into the interior of the basement roof slab 1. The connection position of the waterproof coating 53 is supported and pushed by the support blocks 52 to maintain continuity and prevent it from falling off. It is used as a waterproof structure inside the third basement roof slab 1.

[0032] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
