Abstract

The invention discloses a double-row pile-slab type foundation pit support system and a construction method thereof. The system comprises: two rows of pipe rows, each row of pipe rows includes a plurality of pipe piles, and the plurality of pipe piles in the two rows of pipe rows Two said pipe piles are arranged opposite to each other; a connecting assembly arranged between two adjacent pipe piles in each row of said pipe piles and having a uniform depth with said pipe piles, said connecting assembly includes a vertically arranged The inner casing and the outer casing tightly sleeved on the inner casing, one side of the outer casing is provided with an opening extending upward from the bottom end, one of the two adjacent pipe piles is connected to the outer casing The pipes are seamlessly connected, and the other pipe pile is seamlessly connected with the side of the inner casing passing through the opening; the support for supporting the two rows of pipe piles is arranged on the two rows of pipe piles between. The invention effectively solves the problems of low strength and poor bending resistance of existing single-row steel structure piles.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a double-row pile plate foundation pit support system and a construction method thereof. Background technique [0002] Foundation pit support refers to the support, reinforcement and protection measures adopted for the side walls of the foundation pit and the surrounding environment in order to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. At present, the foundation pit support in soft soil areas is mainly divided into two types: reinforced concrete structure and steel structure according to the material. The reinforced concrete structure foundation pit support system mainly includes underground diaphragm walls, bored piles, etc. It mainly includes SMW construction method piles, steel pipe piles, etc. Steel structure foundation pit protection piles are widely used in foundation pit protection p...
