Description

Waterproof reinforced structure of building foundation Technical Field The application belongs to the technical field of building waterproofing, and particularly relates to a building foundation waterproof reinforcement structure. Background The building foundation is classified into a natural foundation and an artificial foundation, and the foundation which can directly bear the load of the building without being treated is called a natural foundation, whereas the foundation which is treated by the foundation treatment technology is called an artificial foundation. In order to prevent groundwater from entering the structure or the interior of a building and affecting the quality and safety of the structure or the interior of the building, the artificial foundation is subjected to waterproof treatment in the process of construction, and waterproof operation is generally performed by paving waterproof coiled materials on the bottom of the artificial foundation. The existing waterproof and drainage method in the foundation requires excessive time for construction, so that the construction period is unexpectedly prolonged, huge construction cost burden is caused, and economic loss is caused due to construction period delay, so that a ground improvement method capable of rapidly, continuously and smoothly draining and blocking water when foundation construction is performed on the excavated ground is urgently needed. Disclosure of utility model The application aims at solving the technical problems, and provides a waterproof reinforcement structure for a building foundation, which can improve the higher waterproof drainage performance of the building foundation. The application provides a waterproof reinforcement structure of a building foundation, which comprises a foundation pit and further comprises: The first permeable layer is spread at the bottom of the foundation pit; a first filler layer disposed over the first permeable layer; a second permeable layer disposed over the first filler layer; a sand layer disposed over the second permeable layer; The waterproof layer is arranged above the sand layer; The second filling layer is arranged above the waterproof layer; the drainage mechanism is connected with the second permeable layer and used for draining water penetrating upwards, and comprises a drainage piece, a cover body and a supporting component, wherein the drainage piece is connected with the cover body through a fastening piece; Wherein, the drainage piece, the lid are arranged in the both sides of second permeable layer respectively, the drainage piece is equipped with the water drainage tank that is used for the water flow. The first permeable layer is made of non-woven fabrics or synthetic fiber fabrics, can be used for rapidly removing gap water discharged to the surface in the leveling step, except for absorbing water and guiding the water to the upside, when a large amount of water flows in from underground water, the first permeable layer further serves as a horizontal drainage material and provides a bypass path for an underground water layer, the underground water passing through the first permeable layer can be continuously upwards guided in the first filling layer, meanwhile, the drainage mechanism is conveniently arranged in the first filling layer, the first filling layer comprises soil backfilling excavated by a foundation pit, the second permeable layer absorbs water in the sand layer and the first filling layer, the second permeable layer is connected with the drainage mechanism, water is guided into the drainage mechanism through the second permeable layer, then the underground water is rapidly guided and discharged through the drainage groove, the second permeable layer is clamped between a drainage piece and a cover body, the drainage piece is connected with the cover body through fasteners such as bolts or screws, the connection stability between the drainage mechanism and the second permeable layer is improved, the structural stability between the drainage mechanism and the first filling layer is improved through a supporting component, the sand layer water absorption rate is low, the sand layer can be prevented from being upwards guided, the PP (polypropylene) can be completely prevented from flowing through the water bearing layer or the PE (polyethylene) can be completely filled up through the waterproof layer, and the waterproof layer can be completely made into the waterproof layer.
