Description

Technical Field

[0001] The utility model relates to the technical field of underground construction, in particular to a device for removing the blind area of ​​a cutter head of a pipe jacking machine. Background Art

[0002] The rectangular pipe jacking machine is a kind of equipment used for underground space construction, especially suitable for the construction of subway stations in prosperous urban areas. It can carry out construction under conditions such as no closed traffic, no relocation of pipelines, low noise and little dust. The design of the rectangular pipe jacking machine makes its cross-section present a rectangular shape. This design adapts to specific construction needs. It can cut and excavate underground through earth pressure balance or mud water balance. It is widely used in the construction of facilities such as underground comprehensive pipeline corridors, subway entrances and exits, crosswalks, vehicle tunnels and subway tunnels.

[0003] In the existing rectangular pipe jacking machines, the cross-section of the pipe jacking machine is rectangular in shape, which makes it difficult for the cutter disc to cover the entire cross-section, resulting in many blind spots in the cross-section. Because these blind spots are not covered by the cutter disc, there will be great safety risks during construction. Especially in some large-section pipe jacking machines, if the entire blind area exceeds 10%, the pipe jacking machine will encounter various problems during construction, such as failure to jack normally, displacement of the entire machine, and ground deformation. At this time, it is necessary to open the warehouse to deal with the blind spot. At present, since existing pipe jacking machines rarely have manned warehouses, various measures such as strengthening the soil are required to deal with the blind spots. This not only has a long processing cycle and high cost, but also causes long-term downtime, resulting in huge economic losses and delays in construction progress. In addition, when dealing with blind spots, it may also bring safety risks to personnel, which cannot meet the operational requirements of existing rectangular pipe jacking machines.

[0004] Therefore, how to provide a blind spot removal device for the cutter disc of a pipe jacking machine, which can remove the accumulated debris in the blind spot of the cutter disc, effectively dredge the blind spot of the soil bin, and ensure the safety of construction personnel while reducing the cycle and cost of blind spot processing has become a technical problem that needs to be urgently solved by technical personnel in this field.
