Abstract

The invention provides a construction method of a basement outer wall. The basement outer wall is constructed in a mode of disassembling a middle beam, the safety of a foundation pit is ensured in the process of disassembling the middle beam through replacing supports with support steel pipes, after the supports are replaced, steel bars are arranged in guard posts, the inner sides of the guard posts are smoothened with mortar so as to form water-proof layers, and then, the guard posts are welded with the steel bars by split bolts. A building area within red lines is sufficiently utilized under the conditions of ensuring construction safety and construction quality, and project benefit is improved. Besides, only formwork on one side needs to be propped during construction, one construction procedure is eliminated, the construction period is shortened, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for a basement exterior wall. Background technique [0002] With the progress of urbanization, construction land is becoming increasingly scarce. In order to obtain the largest usable area on the limited land, the building uses the height space to become a high-rise building on the one hand, and develops underground to utilize the underground space on the other hand. These two trends all make the basement of the building deeper and deeper, and the depth of the foundation pit excavated by the building increases accordingly. In order to ensure the stability of the foundation pit during the construction phase and the safety of surrounding buildings, municipal roads and facilities, enclosure structures and support systems will be used for deeper building foundation pits. [0003] The construction work of the basement exterior wall is usually afte...
