Reinforced concrete bottom plate cutting method based on wire saw process

Abstract

The invention discloses a reinforced concrete bottom plate cutting method based on a wire saw process. The method comprises the following steps: 1) determining a reserved area and cutting edge lines according to a cutting range of a bottom plate, drawing a plurality of cutting lines in the cutting area surrounded by the cutting edge lines, and determining drilling positions; 2) using a drilling machine to drill holes at the drilling positions, wherein the hole diameter is larger than the diameter of a directional wheel of a wire saw cutting device; 3) cutting reinforced concrete by the wire saw cutting device along the cutting lines, and moving cut reinforced concrete block out of the cutting area by using a hoisting machine. According to the method, the reinforced concrete bottom plate isbroken by the diamond wire saw process, dismantling speed is high, noise is low, and the influence on the structure in the dismantling process is small.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method for cutting a reinforced concrete floor based on a wire saw process. Background technique [0002] In recent years, diamond wire saws have been widely used in the demolition of reinforced concrete beams, columns, side walls, and roof members of buildings (structures). The diamond wire saw cutting process is a static breaking process, which has the following advantages: it can reduce the impact on the structure during the demolition process; the operation is simple and the demolition speed is fast; because the cutting is completed as a whole piece, it is easy to clean up the building slag and the cleaning speed is fast ;The deformation of the steel bar in the reserved part is small; at the same time, the wire saw has low noise and less dust. In daily life, there is also a need to remove the structural bottom plate, and it is difficult to effectively remove the bottom...

Problems solved by technology

In daily life, there is also a need to remove the structural bottom plate, and the conventional diamond wire sawing process is difficult to effectively remove the bottom plate structure

[0003] At present, for floor demolition, air compressors with air guns and excavators with crushing heads are mostly used for crushing, which have the following disadvantages: the demolition vibration is large, which has a great impact on the structure; The machine has high requirements on the site space; the concrete blocks are broken into small pieces, which is troublesome to clean up, resulting in slow demolition speed; after breaking, the steel bars are deformed and difficult to straighten, and the later steel bar construction progress is slow; the noise is loud, which is not conducive to construction; the dust is large and the dust is reduced difficulty
