Abstract
Description
technical field
[0001] The invention relates to the technical field of underground engineering construction, in particular to a tunneling perfusion support construction equipment and method. Background technique
[0002] During the excavation and construction of underground space, such as the construction of mine roadways and subway tunnels. Usually, a boring machine is used for excavation, and the excavated underground space is supported for each section of excavation, so as to avoid the occurrence of roof caving or surrounding collapse in the underground space.
[0003] At present, the technical problems existing in the excavation construction of underground engineering mainly include the following two points: (1) When supporting, it is necessary to withdraw the roadheader first to leave the space required for the supporting construction, and transport the equipment required for the supporting construction It takes a long time to switch between support and excavation work...
