Problems solved by technology

[0002] Now the speed of urban renewal and construction is very fast, and a large number of old buildings are demolished every day. There are currently two ways to demolish old buildings, one is demolition with excavators, and the other is demolition by blasting, but the current demolition process No matter excavator demolition or blasting demolition is used, but no matter whether excavator demolition or blasting demolition is used, the building is completely pushed to the ground, and in the process of fully pushing the building, the buildings are not classified and demolished. , there is a huge waste of resources in the demolition process

Embodiment 1

[0045] A method for sorting and dismantling abandoned buildings, comprising the following steps,

[0046] S1: Removal of metal doors, metal windows and metal hangings on buildings;

[0047] Metal doors, metal windows and metal pendants on buildings are recyclable, and they should be removed by manual removal first, which can save precious resources.

[0048] S2: Use the excavator to push the building;

[0049] S3: Use the cutting machine to cut the building while spraying water mist, and cut the building into several independent and unconnected blocks;

[0050] Cutting the building into independent blocks with a cutting machine is for the convenience of subsequent crushing, and spraying water mist while cutting is to prevent dust from splashing during cutting, and because the high-speed rotation of the cutting machine will generate a large amount of dust Spraying water mist can absorb heat and cool down, so as to prevent the wallpaper, decorative cotton, plastic and wires on...

Abstract

The invention discloses a classified dismantling method for a waste building. The method comprises the following steps that metal doors, metal windows and metal hanging ornaments on the building are demolished; the building is pushed down by using an excavator; a cutting machine is used for spraying water mist and cutting the building at the same time, and the building is cut into a plurality of independent and disconnected blocks; a shovel head on the excavator is dismounted, and is replaced with a breaking head, then the blocks are broken into particles and a steel bar net rack through vibration by means of the breaking head, wood and plastic are separated through vibration, and the wood and the plastic are collected separately; the steel bar net rack is taken from a particle pile, the steel bar net rack is impacted by by utilizing water flow with the pressure of 20Mpa, residual cement particles on the steel bar net rack are shaken off, the steel bar net rack is blown to be dry by utilizing air flow, and then the steel bar net rack is compressed into a metal ingot; and a cable and a data cable are taken out of the particle pile, collected and then placed under an extruding machine to be extruded, and cement blocks adhering to the cable and the data cable are smashed.

Description

technical field [0001] The invention relates to the field of urban construction, in particular to a method for sorting and dismantling abandoned buildings. Background technique [0002] Now the speed of urban renewal and construction is very fast, and a large number of old buildings are demolished every day. There are currently two ways to demolish old buildings, one is demolition with excavators, and the other is demolition by blasting, but the current demolition process No matter excavator demolition or blasting demolition is used, but no matter whether excavator demolition or blasting demolition is used, the building is completely pushed to the ground, and in the process of fully pushing the building, the buildings are not classified and demolished. , there is a huge waste of resources in the demolition process. [0003] Due to the relatively backward construction technology and the relative lack of building material resources, most of the old buildings are low-rise buil...
