Problems solved by technology

[0003]Currently, the comprehensive utilization rate of wood in our country is only 63%. Although some waste wood is recycled, it is often regardless of good or bad, and is directly transported to small wood processing factories or made Burning firewood, resulting in a large amount of waste wood with high value and low use
Waste wood recycling is mostly carried out by stragglers, and it is difficult to form a scale. The city, district (county), street (township, town), neighborhood committee (village) waste wood recycling system has not yet been established

Embodiment

[0018] The present invention will be described in detail below by taking the Guiyang Future Ark project as an example.

[0019] The project covers a total area of ​​9.53 square kilometers, with a construction land of 5,600 mu, a construction area of ​​about 8.5 million square meters, and a planned resident population of about 170,000. After completion, it will become the city center of Guiyang in the next 30 years, the world's leading central park area in Southwest China, and the sub-center of Guiyang city integrating world-class tourism engine, comprehensive livable new city and iconic ecological corridor. It is a major landmark engine project to realize the reconstruction of urban functional space and the upgrading of urban image.

[0020] The Future Ark project uses a large amount of waste wood from construction sites as raw materials, and uses automatic butt joint machines to lengthen the waste wood for reuse.

[0021] The specific method is:

[0022] 1. Build ...

Abstract

The invention discloses a recycling technique of construction waste wood lumps. The technique includes: piling construction wastes in four types, namely, wood, metal, textile and brick; setting a wood processing yard on a construction site, and abutting short wood lumps into long ones for recycling. The waste wood lumps can be connected to long ones within 4 m in length; by calculation according to the conventional specification 2 m, comprehensive cost for processing of each single wood lump is about 2.5 RMB, special wood glue is used, the cost for connecting of each long one is about 0.6 RMB, and 10 wood lumps can be processed per man per hour. Economic cost is evidently lowered, and benefit is significantly improved. The recycling technique is mainly applicable to outskirt construction sites; the lengthening technique is also applicable to large-scale production of wood lumps in wood lump factories.

Description

technical field [0001] The invention relates to a process method for recycling waste and old wooden squares in building construction, and belongs to the technical field of recycling of construction waste. Background technique [0002] In recent years, the pace of urban transformation in my country has accelerated, the real estate and home improvement industries have risen rapidly, and a large number of decoration leftovers have emerged. According to estimates by experts, including old furniture, waste wood removed from renovation of old houses, disposable wood products, waste wood from construction projects, old dead wood and other urban waste wood, my country's cities produce about 85 million tons of waste wood every year. Among them, the waste wood from construction projects accounts for the vast majority, and the main part is the large amount of wood sawn by the concrete formwork project, which has to be discarded because the length is not enough. At the same time, vario...
