Problems solved by technology

[0005] The purpose of the present invention is to provide a construction method for the column replacement structure of the reinforced concrete horizontal support system of the foundation pit, aiming at solving the positional conflict between the column of the reinforced concrete horizontal support system of the foundation pit and the beam or column of the underground structure or the load-bearing wall in the prior art, Direct removal or partial removal of existing columns will lead to instability of the support system

Abstract

The invention relates to the technical field of a foundation pit reinforced concrete horizontal supporting system and discloses a construction method of an upright replacement structure for the foundation pit reinforced concrete horizontal supporting system. The construction method comprises the following steps of: pouring an upright foundation at the bottom of a foundation pit; erecting a formwork on the upright foundation and pouring novel upright concrete; arranging a bracket structure reinforcement at the joint of the new upright and each horizontal supporting beam and pouring concrete; if the horizontal supporting system is only provided with one layer of horizontal supporting beam, disassembling the existing upright replaced with the new upright; and if the horizontal supporting system is provided with a plurality of layers of horizontal supporting beams, pouring a plurality of sections of new uprights from bottom to top and correspondingly connecting the plurality of sections of new uprights to the upper and lower adjacent layers of horizontal supporting beams. By utilizing the construction method, the new uprights can be poured in the foundation pit; the positions of the new uprights avoid beams, pillars and load bearing walls of a subsurface structure; when the new uprights are maintained well, the existing uprights replaced with the new uprights can be disassembled; and due to the supporting effect of the new uprights, instability of the horizonal supporting system cannot be caused.

Description

technical field [0001] The invention relates to the technical field of a reinforced concrete horizontal support system for a foundation pit, in particular to a column replacement structure of a reinforced concrete horizontal support system for a foundation pit and a construction method thereof. Background technique [0002] In the excavation process of foundation pit engineering, the combined support system of piles (walls) and internal supports is a commonly used support structure. The support system includes horizontal supports, waist beams and columns. In the field of building deep foundation pit support, the horizontal support and waist beam are usually reinforced concrete structures, and the columns can be steel pipe concrete columns or steel structure columns. The column is embedded in the column pile below the bottom of the foundation pit, and should be inserted to a certain depth to play a fixed role. [0003] In the foundation pit support design stage, the positio...
