Adjustable conveying belt muck discharging method for high-slope-ratio entrance and exit channel

Abstract

The invention discloses an adjustable conveying belt muck discharging method for a high-slope-ratio entrance and exit channel. Aiming at urban underground excavation subway stations complex in geological condition and peripheral pipelines, construction safety can be ensured better by excavating entrances and exits downwards, the construction risk is reduced, but if the entrances and the exits are subjected to downward excavation construction, muck is difficult to transport. According to the adjustable conveying belt muck discharging method for the high-slope-ratio entrance and exit channel, the problem that downward excavation construction of the entrances and the exits of a subway station is difficult to conduct is effectively solved by introducing an adjustable conveying belt; during construction, the problem that the high-slope-ratio entrance and exit channel is difficult in muck discharging is solved emphatically from the aspects of conveying belt type selecting, designing, machining, field installing, using and the like, and valuable experience is provided for downward excavation construction of more and more high-slope-ratio entrances and exits in the future; and through practice testing, the adjustable conveying belt muck discharging method is feasible, and the industrial problems which cannot be solved through existing technologies are solved.

Description

technical field [0001] The invention relates to a slag discharging method, more specifically, to a conveyor belt slag discharging method with an adjustable entrance and exit channel with a large gradient. Background technique [0002] Muck is just one type of construction waste. According to the "Regulations on the Management of Urban Construction Waste", the term "construction waste" refers to the waste soil generated by the construction unit, the construction unit, new construction, reconstruction, expansion and demolition of various buildings, structures, pipe networks, etc., as well as the process of residential decoration. , discarded materials and other waste. [0003] Beijing Metro Line 14 is a very important traffic trunk line in Beijing's urban rail transit. Among them, Puhuangyu Station of Line 14 and Puhuangyu Station of Line 5 transfer through the transfer channel; the floor of Puhuangyu Station of Line 14 is buried at a depth of 30m, and the roof is covered wit...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to: aiming at underground digging subway stations in cities with complex geological conditions and surrounding pipelines, the use of drooping (downward excavation) at the entrance and exit can better ensure construction safety and reduce construction risks, but it is difficult to transport muck and soil when using drooping at the entrance and exit , this patent effectively solves the difficult problem of construction organization of subway station entrances and exits by introducing adjustable conveyor belts

[0005] During the construction, the problem of difficult slag removal from entrances and exits with large slopes was solved in terms of conveyor belt type selection, design, processing, on-site installation, and use, providing valuable experience for more and more large-slope entrances and exits in the future. Practice has proved that this method is feasible
