Abstract

The invention discloses a muck separating and utilizing device and a muck separating and utilizing method for deviation rectification and side-turning prevention of a tunneling machine. The muck separating and utilizing device comprises a muck extractor, a soil box, a soil discharging pipeline, a soil discharging pump, a soil taking gate valve, a soil taking pipe and a muck filtering mechanism. The soil discharging pipeline comprises a front road soil discharging pipe and a rear road soil discharging pipe; the muck filtering mechanism comprises a three-way valve and a filtering plate; two ports of the three-way valve are respectively connected with the front road soil discharging pipe and the rear road soil discharging pipe; the other port of the three-way valve is connected with the soil taking pipe through the soil taking gate valve and the filtering plate is arranged at the other port of the three-way valve; the muck extractor is used for extracting muck generated in a tunneling process and then storing the extracted muck in the soil box; the soil discharging pipeline is connected with the soil box; the soil discharging pump is arranged on the soil discharging pipeline and is used for discharging the muck to the muck filtering mechanism for distribution through the front road soil discharging pipe; and a part of muck flows into the soil taking pipe for deviation rectification and side-turning prevention of the rectangular tunneling machine through the filtering plate therefore the recycled muck is separated by size and the unblocked pipeline is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device and method for separating and utilizing dregs used for deviation correction and side rotation prevention of roadheaders. Background technique [0002] In recent years, with the continuous development of domestic urban rail transit and the continuous development of urban underground space, rectangular tunnels have been increasingly put into construction because of their superiority in effective cross-section utilization over circular tunnels. [0003] Waste slag generated during excavation of rectangular tunnels is extracted by a screw machine, stored in a soil box, and then discharged by a soil discharge pump. At present, during construction, a part of the waste muck can be used for rectifying the deviation of the rectangular tunnel boring machine, preventing side rotation and filling the space through a set of special devices and pipelines. However, there...
