deep basement support

Abstract

The invention discloses a deep basement support. The deep basement support is characterized in that engineering piles are applied to first-layer steel upright columns foundation piles and foundation piles of second-layer steel upright columns 7, and inner rings are arranged according to arranging conditions of the engineering piles; outer rings are arranged according to plane conditions of a basement, the outer rings are tangent to inner sides of support row piles, and the outer rings are elliptical or circular; the area formed by first-layer basement inner ring beams is 7-18M2, and the area formed by second-layer basement inner ring beams is 20-35M2; sectional sizes of the first-layer basement inner ring beams and the second-layer basement inner ring beams are equal, the first-layer basement inner ring beams and the second-layer basement inner ring beams are 500-700mm in height, and first-layer basement outer ring beams and second-layer basement outer ring beams are 500-700mm in height; concrete beams or steel beams are applied to first-layer diagonal braces, second-layer diagonal braces and angle braces, sections of first-layer steel upright columns and sections of the second-layer steel upright columns are the same, the sections of the first-layer steel upright columns and the second-layer steel upright columns are square, and side length of the squares is 800-1000mm.

Description

technical field [0001] The invention relates to deep basement support and is suitable for the field of building construction. Background technique [0002] At present, in urban development and construction, the land resources in the city are in a situation where every inch of land is very expensive. The basement is getting deeper and deeper. At the same time, the surrounding environmental protection requirements are getting higher and higher during basement construction. For deep basement construction in downtown areas, any guarantee for the safety of basement construction It is a difficult problem in the engineering field, especially the construction safety of basements with more than three floors is more difficult to deal with. Contents of the invention [0003] The invention provides a deep basement support to solve the problem of construction safety of the deep basement support. [0004] For this reason, among the present invention, one deck of steel column foundation...
