Abstract

The invention discloses a basement waterproof construction method, comprising: excavating to form a basement pit structure; pouring a first concrete cushion; building a permanent wall on the edge of the first concrete cushion, and building a temporary wall on the upper part of the permanent wall; Lay the first waterproof membrane layer, turn the first waterproof membrane layer along the permanent wall to the temporary wall, and temporarily fix it with the temporary wall; pour the first structural bottom plate, and pour the structural side on the edge of the first structural bottom plate The structural side wall is parallel to the permanent wall; the temporary wall is removed, and the second waterproof membrane layer is laid on the surface of the structural side wall facing the permanent wall; the protective wall is built on the permanent wall; the backfill is filled and the upper part is poured Concrete cushion; laying the third waterproof membrane layer, so that the third waterproof membrane layer and the second waterproof membrane layer form an overlap; pouring the second structural bottom plate. Provides reliable waterproofing qualities for basement structures.

Description

technical field [0001] The invention belongs to the field of basement waterproof construction, and more specifically relates to a basement waterproof construction method. Background technique [0002] At present, the prior art about the basement waterproofing construction method is a common practice, which only outlines the main points of construction, and fails to provide further targeted treatment methods or construction techniques. In construction projects, when encountering special geographical conditions or construction foundations, it is often necessary to discuss with the site conditions, professional construction experience, domestic and foreign construction cases and expert demonstrations to confirm the construction method, but most of these The reference of the scheme of special argument is not very great. If all the key and difficult parts in the common characteristics of the same type of basement waterproof structure are built with inherent, advantageous and dir...
