Abstract

The invention provides a support structure and a construction method for a sandbar combined tile-plate type foundation pit. The foundation pit support structure includes: tiles and purlins; wherein, the tiles are arranged along the entire circumference of the foundation pit wall of the foundation pit, so that a circle of support walls is arranged around the foundation pit wall plate; several circles of purlins arranged side by side along the height direction of the foundation pit are arranged inside the supporting wall plate, and the purlins of each circle are connected with the tile boards through struts. to support the tile on the wall of the foundation pit. The construction of the present invention does not need to occupy a large site, and construction can be carried out in a narrow space, saving mechanical construction space, and the excavation surface of the foundation pit is small, which can effectively solve the problems of construction in a narrow space and difficult construction of side wall pipe openings.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a sandbar composite tile-type foundation pit support structure and a construction method thereof. Background technique [0002] With the rapid development of the city, the buildings in the city are becoming denser and denser. In the face of complex geological conditions such as deep foundation pits and high groundwater levels, the support form is single, and the cost of using the support form is high, which is difficult to meet a large number of wells. Low-cost construction requirements for foundation pits. [0003] At present, in the face of complex environments, a variety of combined foundation pit support structures have been formed, and cement mixing piles, bored piles, Larsen steel sheet piles and other support combinations are mostly used, although they can play a good role in supporting the foundation pit. However, for a large number of water supply and dra...
