Damp-proof method for bottom-layer house

Abstract

The invention discloses a damp-proof method for a bottom-layer house. The damp-proof method comprises the following steps that (1) floors in the house are excavated away, then the ground is downwards excavated to form a damp-proof cavity with the depth being 0.5-0.8 m, the bottom surface of the damp-proof cavity is filled with a layer of cobble, then a steel bar net is laid on the cobble, and a concrete layer is laid on the steel bar net; and (2) a brick wall is made through bricks along the inner wall of the damp-proof cavity, and then concrete formed by mutually mixing one part of sand with the particle diameter being 0.25 mm and two parts of cement is used to whitewash the wall surface. According to the damp-proof method for the bottom-layer house, the purpose that damp-proof construction treatment is conducted on a resident at the bottom layer is achieved so that damp air on the ground can be effectively removed to enable the resident to have a good residence environment; and by sprinkling water in the front, the concrete can absorb the water, and the effect that the completely-dried concrete is solider can be ensured accordingly.

Description

technical field [0001] The invention belongs to the field of ground moisture-proof technology, and in particular relates to a moisture-proof method for ground-floor housing. Background technique [0002] Under the existing living environment, the ground floor is often not welcomed by everyone, because there is a lot of moisture in the ground floor housing, which will have a great impact on the body, and the comfort of living on the ground floor is very poor. The bottom surface is treated with moisture-proof treatment. At this time, if the concrete is not sprayed with water, it is easy to cause the concrete to not absorb enough water when it is dry, so that it cannot be well combined with the sand, resulting in the entire concrete layer being weak, and the sand is easy to fall off from the concrete layer. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a moisture-proof method for the ground-floor hous...
