Abstract

The invention provides a sequential construction and reversed constructionclockwise and counter-clockwise combined construction method of an irregular planar deep foundation pit. The method is characterized by comprising the following steps: step 1, preparation for construction; step 2, pile driving construction of engineering piles, a building envelope and support upright piles; step 3, foundation pit dewatering; step 4, first excavation; step 5, construction of first ground floor plate bottoms and beams of an inverse operating area, and construction of first supports of a central area and a narrow and long area; step 6, second excavation; step 7, repeating the steps 5 and 6 to carry out the excavation of a second ground floor and a third ground floor; and step 8, dismantling a support device. The construction method has the advantages of being better in supporting quality of foundation pit, safer to operate and relatively lower in construction cost, and the total period of construction can be shortened; furthermore, the construction method has the characteristics of advancement, novelty, energy conservationsaving, environmental protection and the like, and the significant social benefits can be realized.

Description

technical field [0001] The invention relates to a foundation pit construction method, in particular to a construction method combining forward and reverse directions for a special-shaped plane deep foundation pit. Background technique [0002] Due to the limitation of construction sites and the requirements of architectural design, there are more and more irregular plane shapes in the construction of deep foundation pits in modern buildings, which brings great difficulty and high support engineering costs to the construction of deep foundation pits in basements . Compared with the traditional construction method, the super-large-area complex special-shaped plane deep foundation pit combined with forward and reverse construction method shortens the total construction period, the foundation pit support quality is better, safer, and the project cost is relatively much lower. It is advanced, novel and energy-saving. , environmental protection and other characteristics, the soci...
