A construction method of basement exterior wall

Abstract

The invention relates to a basement exterior wall construction method. The basement exterior wall construction method comprises the following steps that S1, an exterior wall upturning part is constructed, specifically, a basement raft is constructed, the exterior wall upturning part with the height being 40 cm-50 cm is arranged on bottom plate concrete, an L-shaped pulling rod is pre-embedded in the exterior wall upturning part, and the exterior wall upturning part and the bottom plate concrete are poured jointly; S2, an exterior wall middle section is constructed, specifically, after the exterior wall upturning part is constructed, formworks are mounted on the two sides of an exterior wall steel bar skeleton corresponding to the exterior wall middle section, an L-shaped pulling rod is pre-embedded in the upper end of the exterior wall middle section, then concrete is poured to complete construction of the exterior wall middle section, and the height of the exterior wall middle sectionis 300 cm-310 cm; and S3, an exterior wall upper section is constructed, specifically, formworks are mounted on the two sides of an exterior wall steel bar skeleton corresponding to the exterior wallupper section, then concrete is poured to complete construction of the exterior wall upper section, and the upper end of the exterior wall upper section reaches a basement roof. The basement exteriorwall construction method has the advantages that the waterproof effect is good, the appearance quality is good, operation is easy, and materials are saved.

Description

technical field [0001] The invention relates to the field of underground structure construction, in particular to a construction method for an outdoor wall of a basement. Background technique [0002] With the rapid development of urban rail transit, buildings have higher and higher waterproof requirements for underground structures, especially for basement equipment rooms and public areas, which have higher requirements for anti-seepage and anti-leakage of structures. At present, most projects basement external wall formwork reinforcement Water-stop tie rods are often used for reinforcement, and a large number of tie rods are required, which will adversely affect the integrity of the exterior wall concrete, cause cracks and cause water seepage, and the position of the outer tie rod eye is prone to grout leakage, which will affect the quality of concrete molding. Repairing the tie rod eye increases the workload, and has a great influence on the repair quality of the tie rod ...
