Construction waste slag removing system and method for open type heading machine

Abstract

The invention provides a construction waste slag removing system for an open type heading machine. A slag removing belt is arranged in a tail area of the heading machine in an inclined mode. The head end of the slag removing belt is located on the lower side and fixedly installed on a support. The support is connected with a trailer of the heading machine. The tail end of the slag removing belt is fixedly installed on the top of the trailer of the heading machine. A slag discharging hopper is arranged at the tail end of the slag removing belt and is in lap joint with a movable chute. The movable chute is in lap joint with a continuous belt of a tunnel. The invention further provides a construction waste slag removing method for the open type heading machine, wherein the construction waste slag removing system is adopted. The construction waste slag removing method comprises the steps that firstly, construction waste slag is piled close to the head end of the slag removing belt; secondly, when the heading machine starts heading and the continuous belt of the tunnel is started, the slag removing belt is started; thirdly, the waste slag is manually shoveled to the slag removing belt, and the waste slag is conveyed to the continuous belt of the tunnel from the slag hopper and the movable chute; finally, construction waste slag is removed. By the adoption of the construction waste slag removing system and method for the open type heading machine, construction waste slag can be completely removed, and the slag removing efficiency is high; the problem that a train occupies a rail is avoided, and the construction period can be effectively shortened.

Description

technical field [0001] The invention relates to the construction field of an open roadheader, in particular to a system and a method for cleaning construction waste slag of an open roadheader. Background technique [0002] The excavation operation of open TBM (hard rock tunnel boring machine) will generate a large amount of construction waste, which mainly occurs in three areas, such as Figure 4~6 Shown: Area 1, Area 2 and the tail area. Area 1 is mainly the rocks on the top arch that collapsed naturally after the shield came out. Area 2 is the rebound material produced after concrete spraying. The tail area is cleaned by the concrete tanker. Spoil. The muck in the first area is relatively close to the spoil lifting bucket and there is a small loader for loading the muck, which can be transferred to the belt of the main engine through the spoil lifting bucket and then transported to the outside of the tunnel by the continuous belt of the tunnel; while the rebound in the sec...

AI Technical Summary

Problems solved by technology

[0003] Conventional slag removal operations have a great impact on the normal excavation of TBM

Because the TBM construction spoil cleaning requires trains to occupy the road, and the tunnel transportation adopts single-lane transportation, resulting in the inability of other vehicles to pass during the road occupation of the slag removal train

The main influencing factors are: the slag cleaning machine and the train occupy the transport track in the cave to block the traffic; the material crane in the installation room will affect the lifting of construction materials in the cave; Unable to cut materials, these factors lead to the inability to transport concrete and other materials to the TBM in time
