Description

Technical Field

[0001] The invention relates to the field of civil engineering, in particular to a waterproof remedial structure for a garage fertilizer tank. Background Art

[0002] For TOD projects, generally after the foundation construction is completed, the fertilizer trough will be backfilled, and an overhead floor will be built above the backfill soil to connect with the surrounding structure to form a whole. After being put into use, the backfill soil is not compacted enough due to various reasons. As time goes by, the pasted waterproof membrane will separate from the concrete floor. During the rainy season, the accumulated rainwater will enter the gap between the waterproof membrane and the concrete floor through the cracked parts of the membrane, and then seep into the cracked parts of the floor. Although the leakage that occurs after being put into use has no effect on the safety of the structure, it has caused great trouble to the owners. There are complaints whenever it rains, and repairs are required, resulting in frequent complaints.

[0003] When designing the overall construction drawing, the setting of the sump meets the requirements of the specification, and there is no need to set up a separate sump in such parts (garage fertilizer tank, floor overhead parts). This leakage phenomenon does not occur in all projects, and there is uncertainty. However, once leakage occurs, it is easy to cause losses to the owner and cause relevant complaints, which need to be handled as soon as possible.

It has strong flexibility and can fundamentally solve the technical problem of garage fertilizer trough water seepage.

[0023] The compaction coefficient of the plain soil layer 1 is not less than 0.95. The closer the compaction coefficient is to 1, the better the quality of soil compaction, the higher the density of the soil, the lower the permeability, and the strength and stability of the soil foundation can be improved.

[0024] The particle size of the coarse sand hydrophobic layer 2 is 0.5 mm to 1.0 mm, and the particle size of the coarse sand is uniform, which can fully exert the hydrophobic function.

[0025] Among them, the cushion layer 3 has a thickness of 200 mm and is made of C20 polymer concrete material. The cushion layer 3 can improve the bearing capacity and play a role in supporting the infiltration overflow drainage well 13; the cushion layer 3 can also play a leveling role, reducing the damage caused by uneven soil settlement, so that the separately added infiltration overflow drainage well 13 has a firm and stable structure.

[0027] Among them, the diameter of the seepage drainage pipe 6 is not less than 200mm, and a circular hole is opened on it, the diameter of the circular hole is not more than 10mm, and the opening rate is 5%. The circular holes on the seepage drainage pipe 6 can collect water in the soil into the seepage drainage pipe 6, and then drain it to the infiltration overflow drainage well 13 through the seepage drainage pipe 6, which can effectively deal with the seepage phenomenon.

[0028] Among them, the rigid waterproof layer 8 is a permeable crystallized concrete waterproof layer with a thickness of 50-70mm. The amount of permeable crystallized material used is 2.5kg / ㎡. The permeable crystallized material can effectively exert the self-healing ability of concrete cracks, repair fine cracks in concrete, and improve the strength and impermeability of concrete.

The hydrophobic plate 10 made of HDPE material has the dual functions of drainage and waterproofing, and can protect the integrity of the waterproof layer; it has high compressive resistance, is not easy to deform, and improves the stability and durability of the structure.

[0030] Among them, the infiltration overflow drainage well 13 can be made of high-strength concrete material, which is prefabricated in the factory, can effectively eliminate air pollution, effectively reduce carbon emissions, and achieve green and low-carbon.

[0031] Among them, the infiltration overflow drainage well 13 does not require on-site welding operations and can be installed after being transported to the site. Compared with the traditional sump method, it can reduce on-site construction workers, reduce dust pollution, reduce electricity use risks, and reduce fire approval procedures.

[0032] Among them, the steel steps 18 are arranged on the wall of the seepage overflow drainage well 13 to facilitate the workers to go up and down, which is beneficial to the later equipment maintenance and well wall maintenance.

[0033] Among them, due to the use of concrete material, the total weight of the infiltration overflow drainage well 13 is light and can be transported to the installation site with the help of small lifting tools, which can avoid the use of large lifting machinery for lifting, reduce the operating risks of personnel, and reduce the application procedures for lifting at the construction site.
