Embodiment Construction

[0030] Take the subway shield ground connection wall as an example:

[0031] For the partly demolished ground connection wall of the entrance and exit of the subway shield section, its structure is divided into the part that needs to be demolished and the part that needs to be retained outside the boundary. Taking the ground connection wall with a thickness of 800mm and a height of 10000mm as an example, the specific implementation method is described.

[0032] The purpose of this project is to break a round hole with a diameter of 6700mm in the middle of the ground connection wall. At the same time, in order to ensure the safety of the tunnel door of the shield machine, when the ground connection wall is demolished, only the 600mm thick ground connection wall is removed, and the 200mm thick ground connection wall is retained. The wall serves as a temporary support structure, waiting for the shield cutterhead to break.

[0033] Before the ground wall concrete is poured, two r...

Abstract

The invention discloses a customized dismantled reinforced concrete structure and a static crushing dismantling method of the customized dismantled reinforced concrete structure. The customized dismantled reinforced concrete structure has a portion to be subsequently dismantled and a remaining portion. A stress isolation belt is arranged between the portion to be subsequently dismantled and the remaining portion, and the stress isolation belt is composed of an energy absorption material between two steel plate clamps. A single row or multiple rows of large-diameter embedded pipes are embedded to the portion to be subsequently dismantled to be used as static expansion pipes, so that the crushing effect of the customized partially-dismantled reinforced concrete structure is improved. When the portion to be dismantled finishes the use mission, when dismantling is needed, the end of a plug is filled with an expansion agent, the plug is sealed, and the portion to be dismantled can be structurally disassembled. According to the customized dismantling building structure, the available stable building structure can be fully utilized, the building structure to be dismantled is dismantled with low noise and low potential safety hazard, and energy conservation and environmental protection are better achieved.

Description

technical field [0001] The invention belongs to the technical field of building demolition, and in particular relates to a customized partially demolished reinforced concrete structure and a static crushing and demolition method thereof. Background technique [0002] At present, there is a wide demand for customized partially demolished reinforced concrete structures. For example, the crushing of reinforced concrete ground connection walls in the entrance and exit holes of the subway shield section is most commonly done by manual chiseling or mechanical demolition, but the time is long and the noise is high. Large, high risk, high labor costs; some units also tried to adopt the method of static expansion, but the research depth is not enough, the expansion effect and the area outside the boundary of the crushing area have no effective protection measures, and a complete and effective crushing and demolition method has not been formed. Contents of the invention [0003] In ...
