Description

Technical Field

[0001] The utility model belongs to the technical field of TBM excavation construction, and particularly relates to a slag conveying device for TBM which is convenient for manual loading. Background Art

[0002] The TBM tunnel boring machine is a new and advanced tunnel construction machine that mainly uses a rotary cutter to excavate, crush the surrounding rock in the tunnel, and excavate to form the entire tunnel section. During the excavation process, the TBM cannot completely load the cut debris into the soil bin. The broken debris is easily accumulated at the bottom of the tunnel under the action of gravity. At the same time, the debris will fall during transportation. If the accumulated debris after falling is not cleaned up in time, it will not only affect normal construction, but also pose a great safety hazard to surrounding construction workers. The existing method of cleaning debris is mostly manual. Due to the limitation of manual working height, the debris cannot be directly loaded into the debris conveyor belt. Therefore, the method usually adopted is to manually carry the debris to the debris conveyor belt. The bottom of the tunnel is at a high distance from the debris conveyor belt, which is labor-intensive, affecting the construction progress and increasing labor costs. Utility Model Content

[0003] In order to overcome the problems of high labor intensity and low work efficiency in cleaning debris in the background art, the utility model provides a debris conveying device for TBM that is convenient for manual loading.
