Description
Technical Field
The invention belongs to the technical field of building construction, particularly relates to classified recovery of building garbage, and particularly relates to a classified recovery method of building garbage.
Background
At present, three methods of special channel clearing, construction elevator clearing and platform tower crane lifting are mainly adopted for clearing and transporting floor garbage in the field of building construction in China, and the methods mainly have the following problems and defects:
1. special channel clearing and transporting
1) The special garbage channel is cleaned and transported only to realize vertical transportation of the garbage on the floors, but no garbage classification disposal device is arranged at the outlet, dust pollution is easily formed at the outlet of the channel, the garbage at the outlet is mixed together and is easily hardened into hard blocks, the garbage is inconvenient to clean, the surrounding environment is disordered, and the garbage classification disposal device has great influence on safe civilization construction.
2) The construction waste can not be classified and recycled, so that the resource waste is caused; the construction waste which can be utilized by classification comprises main components of broken stones, stone slag, fine sand and the like, and is a high-quality material for foundation pit backfill and atrial backfill.
3) The water used for washing the pump by the concrete pump can not be recycled, so that the site pollution is serious, and the water resource is not saved.
2. Construction elevator clearing and transporting
1) The floor rubbish is mainly transported through the elevator by the aid of the people-pushing trolley, the method is low in efficiency, the elevator occupies a long time, the service efficiency of the elevator is reduced, labor cost is increased, and cost is high.
2) Environmental protection not convenient for, the department homoenergetic is piled at floor clearance department and scene and is caused very big raise dust pollution, and job site windrow department is unordered, and waste classification is difficult to realize more, the reutilization of not being convenient for.
3) Concrete pump washing pump water is discharged everywhere, and more construction enterprises discharge to the external scaffolding, has great potential safety hazard, and the external scaffolding pollutes seriously, and civilized construction is difficult to realize.
3. Platform tower crane clearing and transporting
1) The method is tightly suitable for multi-storey buildings with few storeys and has large limitation.
2) A special tower crane hoisting platform needs to be built, garbage in a floor is pushed to the hoisting platform through a man-pushing trolley and then hoisted to a site designated place through a tower crane, the personnel intensity is high, the labor efficiency is low, a professional signal worker needs to cooperate with a command tower crane, and the construction cost is high.
3) Is not convenient for environmental protection and is not beneficial to garbage classification and recovery.

1) The method effectively avoids the problems and defects of the traditional method, and the construction waste classification and recovery system consists of two parts, wherein one part is a vertical transportation pipeline 1 arranged on a floor, and the other part is a ground recovery and disposal device; the system can realize dust-free cleaning and classification of garbage on one hand, and can be used as water for washing a pump of a concrete pump to discharge, recover, precipitate and utilize on the other hand; the system is convenient to prepare, safe, stable, energy-saving and environment-friendly, is an effective means for cost reduction and efficiency improvement of construction enterprises, and is a necessary guarantee for safe and civilized construction; the ground recycling and processing device can automatically load the garbage while realizing garbage classification, and reduces secondary loading cost.
2) The method of the invention is provided with the garbage cleaning port on each layer, and the garbage cleaning port is opened when in use and closed when not in use, so that the whole process has no dust pollution.
3) When the method is implemented, the investment of operators is less, mechanical cooperation is not needed, and the efficiency is high.
The technical solutions in the embodiments of the present invention are clearly and completely described above, and the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
