Abstract
The invention relates to the field of house construction, and provides a construction method of a damp-proof wall for solving the problem that after a waterproof layer is abraded, a wall leaks, and consequently the service life of the wall is shortened. According to the following technical scheme, the construction method comprises the steps: S1, an anti-seepage base layer is poured, specifically,S11, a base layer formwork is set up, and S12, anti-seepage concrete is poured to the elevation of the base layer, and after initial setting, the anti-seepage base layer is formed; S2, a reinforcementframe is set up, specifically as follows: the reinforcement frame is fixed in the initially-set anti-seepage base layer, and the bottom of the reinforcement frame is higher than the bottom of the anti-seepage base layer; S3, a wall formwork is set up; S4, the wall is poured; S5, after the wall is initially set, the wall formwork is dismounted; S6, after the wall formwork is dismounted, nanometerhydrophobic powder is sprayed to the wall surface at once; and S7, a waterproof adhesive is sprayed to the wall surface. By adopting the anti-seepage concrete as the base layer to isolate undergroundwater and matching the situation that the bottom of the reinforcement frame is higher than the bottom of the anti-seepage base layer, the underground water is not prone to seeping to the reinforcementframe, thus the reinforcement frame is not prone to being rusted, and the service life of the wall is prolonged.
Description
technical field [0001] The invention relates to the field of house construction, in particular to a construction method for a moisture-proof wall. Background technique [0002] The moisture-proof wall is mainly to resist the erosion of the wall by groundwater or external water, mainly to reduce the corrosion of the steel frame due to the penetration of water towards the wall. [0003] Usually, during the construction of the moisture-proof wall, a waterproof layer is applied on the bottom and the wall surface, so that the moisture is not easy to contact with the concrete wall, and then it is difficult to penetrate into the concrete. [0004] After a long time of use, the waterproof layer is stressed for a long time and is prone to wear and tear. Once the waterproof layer is worn, it is prone to wall leakage and the service life of the wall is reduced. Therefore, there is still room for improvement. Contents of the invention [0005] In view of the deficiencies in the prior...
