Basement bottom plate water drainage layer construction method

Abstract

The invention discloses a basement bottom plate water drainage layer construction method. According to the method, a grait layer is paved at the basement bottom layer part, the self discharge function of the grait layer is utilized for realizing the water drainage, the traditional single water blocking mode is broken, water seeped from the outer wall and the bottom plate of the basement is firstly gathered to an anti-seeping wall water drainage ditch and is then gathered to a water collecting well through entering the water drainage layer to flow freely, and finally, the water is pumped and discharged into a municipal pipe network through an automatic water discharge pump. The water drainage layer is used as an isolation layer between the bottom plate structure and a decoration surface layer, seeped water can be effectively guided out, the dryness of the use surface layer is maintained, a good water drainage effect is reached, and the common quality problem of the basement outer wall and bottom plate seepage is effectively solved.

Description

technical field [0001] The invention relates to a construction method of a basement floor hydrophobic layer. Background technique [0002] When it comes to the waterproofing of basement walls and floors, we first think of various types of coiled materials and waterproof coatings. These traditional waterproofing methods use "blocking" methods, which cannot permanently solve the problem of water leakage, causing basement walls to Leakage of water and bottom plate is still one of the common quality problems, and the waterproof membrane and waterproof coating film are easy to age, it is difficult to maintain the waterproof effect in the later stage, and this kind of waterproof material is not environmentally friendly, and it will discharge toxic substances after long-term use. The drainage system is bad. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for the hydrophobic layer of the basement f...
