Description

Supporting device for tunnel construction Technical Field The utility model belongs to the technical field of tunnel construction, and particularly relates to a supporting device for tunnel construction. Background Along with the development of industry, the construction of tunnel gradually becomes mainstream project, in the tunnel construction process, need confirm in advance according to the concrete condition of rock mass along vertical excavation length at every turn, promptly when being under construction, excavate first section tunnel passageway according to this excavation length earlier, then implement the support in this first section tunnel passageway, after accomplishing, so circulation is gone down, until after accomplishing the support construction of last section tunnel passageway, multistage tunnel passageway just has formed a complete tunnel, consequently, just need support device to carry out a lot of support use in tunnel construction, current support device is lower in tunnel construction flexibility, inconvenient according to tunnel height and width adjustment support area. Disclosure of utility model The utility model provides a supporting device for tunnel construction, which aims to solve the problems that the existing supporting device provided by the background art has lower flexibility in tunnel construction and is inconvenient to adjust the supporting area according to the height and width of a tunnel. The supporting device for tunnel construction comprises a supporting frame, a first clamping plate clamped on the supporting frame, a first connecting block mounted on the first clamping plate, a second clamping plate clamped on the first connecting block, a second connecting block mounted on the second clamping plate, a first threaded rod which is mounted on the supporting frame, the first connecting block and the second connecting block in a threaded mode and used for adjusting the supporting height of a tunnel arc roof, and a top plate which is arranged between the supporting rod and the tunnel roof and used for isolating broken stones. Preferably, the first clamping plate and the second clamping plate are both provided with limit bolts in a threaded manner, the limit bolts on the first clamping plate are in threaded connection with the supporting frame, the limit bolts on the second clamping plate are in threaded connection with the first connecting block, and the bottom of the first threaded rod is provided with an adjusting block for providing an operation holding point. Preferably, a cylinder is installed at the bottom of the second connecting block, a supporting piece for supporting the supporting frame and the supporting piece with the upper structure is arranged in the cylinder, and a base for increasing the contact area between the supporting piece and the ground is installed at the bottom of the supporting piece. Preferably, the support member comprises a threaded cylinder detachably mounted in the cylinder, a second threaded rod which is mounted in the threaded cylinder in a threaded manner and extends out of the threaded cylinder, and the threaded cylinder is matched with the second threaded rod to adjust the support height of the support frame.
