Abstract

The invention discloses a double-row pile plate type foundation pit supporting system and a construction method thereof. The double-row pile plate type foundation pit supporting system comprises two rows of tube banks, connecting assemblies and supporting pieces, wherein each row of tube banks comprises a plurality of tube piles which are oppositely arranged in pairs; the connecting assemblies arearranged between every two adjacent tube piles in each row of tube piles and are uniform with the tube piles in depth; the connecting assemblies comprise inner sleeves which are vertically arranged and outer sleeves which are tightly arranged on the inner sleeves in a sleeving manner; an opening extending upwards from the bottom end is formed in one side of each outer sleeve; one of every two adjacent tube piles is in seamless connection with the outer sleeves, and the other tube pile is in seamless connection with the side, penetrating out of the openings, of the inner sleeves; and the supporting pieces are used for supporting the two rows of tube piles and arranged between the two rows of tube piles. According to the double-row pile plate type foundation pit supporting system and the construction method thereof, the problems that an existing single-row steel structure pile is low in strength and poor in bending resistance are effectively solved.

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...
