Waterproof construction method of drain plate of bottom plate of basement

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a waterproof construction method of a drain plate of a bottom plate of a basement. The method comprises the steps that firstly, clearing, leaking stoppage and leveling are carried out on the bottom plate of the basement; secondly, the drain plate is paved; thirdly, corner shearing and whole surface leveling are carried out; fourthly, a reinforcing mesh is bound; and fifthly, a wear-resisting layer is poured. Through panel design of a concave-convex table of the drain plate, the specific permanenthollow layer, namely, a drain layer, of the drain plate with the supporting point is utilized for dampproofness and water draining, any seepage water of the bottom plate of the basement can be guidedinto a drainage ditch, then guided into a water collection well through the drainage ditch and is finally drawn out by an immersible pump, and it is ensured that the basement is dry. The compressivestrength of the face layer of the bottom plate is guaranteed through concrete in the concave table and is subjected to mechanical design and testing, and the composite compressive strength of the drain plate and the concrete can meet most construction requirements; the price is low, construction is convenient, and the speed is high; and the self weight of a building is reduced, resources are saved, the environment is protected, and good social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a waterproof construction method of a basement floor hydrophobic board. Background technique [0002] Today, with the vigorous discovery of the construction industry, in order to meet the diversified basement space utilization such as parking and storage, the waterproof requirements of the basement floor are getting higher and higher. At present, the commonly used method for basement bottom slab waterproofing is the construction method of self-waterproofing of the bottom slab waterproof concrete plus a flexible waterproof layer, and there is also a construction method of laying stones between the structural layer and the counterweight concrete as a secondary backflow waterproof structure. If only the former method is used when the groundwater level is high, the waterproof layer will be easily broken through. After adopting remedial measures such as grout...

AI Technical Summary

Problems solved by technology

If only the former method is used when the groundwater level is high, the waterproof layer will be easily broken through. After remedial measures such as grouting are used, not only the appearance is not good enough, but the effect is also not ideal.

If the latter is used, laying stones as a secondary backflow waterproof structure will have a better effect and will not leave marks on the surface of the floor. However, due to environmental protection requirements and control of stone mining this year, the cost of laying stones has increased rapidly, and an alternative technology is urgently needed , in the prior art, there is no technology or method that is environmentally friendly, low in cost, convenient in construction, and can replace traditional hydrophobic materials such as pebbles and gravels.
