Inner support wire sawing, lossless cutting and disassembling structure and construction method thereof

Abstract

The invention discloses an inner support wire sawing, lossless cutting and disassembling structure and a construction method thereof. The structure comprises an operating platform, an inner supporting frame and a wire sawing machine. The constructing method comprises the following steps that 1, construction preparation is carried out; 2, the operating platform is arranged at the bottom of an inner supporting beam in a put-up mode; 3, cut fracture surfaces are determined; 4, the wire sawing machine and the operating platform are installed and fixed; 5, the inner supporting beam is cut; 6, concrete blocks are lifted; 7, an air pick is used for crushing the cut concrete blocks. Lossless static force cutting is adopted, disturbance to the structure is small, noise is low, and dust and pollution are avoided; cutting speed is high, efficiency is high, the mechanical degree is high, labor waste is reduced, overall equipment is simple and easy to install, and limitation of sites and space is avoided.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an inner support wire saw non-destructive cutting and demolition structure and its construction method. Background technique [0002] Super high-rise buildings are often built in the central area of ​​the city, close to adjacent buildings and residential areas, even close to subway stations, surrounding commercial streets, etc., with dense crowds, heavy traffic, and complex underground pipelines. In order to save land space, they are often designed to be deep basement, resulting in deep excavation of the foundation pit and many potential safety hazards. In order to ensure the stability and safety of the foundation pit, an internal support system is usually added on the foundation of retaining piles or diaphragm walls. [0003] In the construction process of the basement, the demolition of the internal support in the prior art is usually carried out by the open expl...
