Deep basement supporting construction method

Abstract

The invention discloses a deep basement supporting construction method. The deep basement supporting construction method is characterized by comprising the following construction steps of: (1) constructing a layer of steel column foundation piles, two layers of steel column foundation piles, a layer of steel columns and two layers of steel columns; (2) constructing basement supporting row piles; (3) constructing basement waterproof curtains, and using cement mixing piles as the basement waterproof curtains; (4) constructing a layer of basement inner ring ring-beams and a layer of basement outer ring ring-beams; (5) constructing a layer of diagonal braces and angle braces; (6) carrying out pit earth excavation till reaching the construction elevation of the bottoms of two layers of basement inner ring ring-beams; (7) constructing two layers of basement inner ring ring-beams and two layers of basement outer ring ring-beams; (8) constructing two layers of diagonal braces; (9) carrying out pit earth excavation till reaching the construction elevation of the bottoms of three layers of basement bottom plates; (10) constructing the basement bottom plates; (11) constructing the outer concrete wall of the basement; (12) dismantling the two layers of basement inner ring ring-beams, the two layers of basement outer ring ring-beams and two layers of diagonal braces; (13) constructing two layers of basement floors; (14) dismantling a layer of basement inner ring ring-beams and a layer of basement outer ring ring-beams; and (15) constructing a layer of basement floors.

Description

technical field [0001] The invention relates to a construction method for deep basement support, which is applicable to 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 d...
