Ordered green detachment construction method for building

Abstract

The invention relates to an ordered green detachment construction method for a building. The ordered green detachment construction method for the building comprises the following steps: carrying out field exploration; carrying out state determination for the building; carrying out three-dimensional large-scene scanning; formulating a detachment plan; carrying out reinforcing, modification and three-dimensional monitoring for the building; establishing a point cloud model; re-establishing the point cloud model on the basis of data correction; constructing a three-dimensional building information model; carrying out reverse decomposition in a BIM system to obtain a reverse decomposition scheme for the building; establishing an all-professional building information model, and formulating a building member decomposition list; carrying out green assessment; correcting the reverse decomposition scheme for the building, and re-establishing the all-professional building information model; carrying out ordered green detachment construction and monitoring; carrying out BIM real-time management correction; and carrying out green management for detached objects, recycling evaluation and engineering conclusion and evaluation. Compared with the prior art, according to the ordered green detachment construction method for the building, the reverse decomposition scheme for the building and thegreen assessment are combined on the basis of a complete-period digital system, and in combination with a multiple real-time correction system, so that the solid waste recycling and reutilization degrees for the building can be furthest increased.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an orderly green demolition construction method for buildings. Background technique [0002] As the country with the largest volume of new buildings, China's annual new building area of ​​about 2 billion square meters consumes 40% of the world's building materials, followed by the number of old buildings demolished in China each year reaching 40% of the total number of buildings. %, and the demolition of old buildings per 10,000 square meters produces more than 7,000 tons of construction waste. [0003] The traditional building demolition construction method is only to quickly dismantle the building, there is no order to follow in the construction process, and there is no systematic planning for the prevention of environmental pollution and construction solid waste treatment, which does not meet the requirements of sustainable development. Even if improvements a...

Problems solved by technology

[0004] The above method only analyzes the stress situation of the building, without considering the resource utilization of building demolition and the utilization of solid waste. Different demolition methods and construction techniques have different influences on resource utilization. The present invention aims to use full-cycle digital System, in order to realize the systematic digitization of building demolition engineering, closely combine the green concept of building demolition and resource utilization, and plan the demolition plan in advance. While meeting the construction purpose, it can maximize the integrity of the original building structure, effectively To save resources and improve the utilization rate of construction solid waste
