Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of tunnel engineering, especially relates to tunnel lining hollowing detection device. BACKGROUND

[0002] Tunnel lining refers to the permanent structure that supports and maintains the long-term stability and durability of the tunnel. Its role is: supporting and maintaining the stability of the tunnel, maintaining the space required for train operation, preventing weathering of surrounding rock, removing the influence of groundwater, etc. However, after the tunnel lining is poured and constructed, the whole concrete sinks under the action of gravity, and the lining of the tunnel arch is prone to hollowing. The generation of hollowing will make the tunnel lining structure unstable, directly endangering the safety of driving, so it is necessary to detect and investigate the hollowing in the tunnel lining in a timely manner.

[0003] The existing patent (publication number: CN218629644U) discloses a subway tunnel lining hollowing knocking device, which belongs to the technical field of tunnel engineering. It includes a vehicle body that runs on the track in the tunnel; a driving mechanism installed on the vehicle body for driving the vehicle body to run; a reciprocating knocking mechanism including a knocking hammer and a reciprocating assembly, both of which are installed on the vehicle body. A driven chain is also installed on the vehicle body, and the driving mechanism drives the reciprocating assembly to run through the driven chain. The reciprocating assembly is used to drive the knocking hammer to reciprocally knock the tunnel lining arch in the vertical direction.

[0004] The above-mentioned comparative document points out that the device can replace manual detection and investigation of tunnel lining hollowing, and improve the detection and investigation efficiency of hollowing in the tunnel lining.
