Problems solved by technology

[0003] During the construction of the tunnel, if the condition of the surrounding rock of the tunnel site is found to be poor and does not meet the conditions for the construction of the dark tunnel, in order to ensure the safety of the construction, the weak surrounding rock will generally be excavated and cleared during the construction, and then the open construction of the dark tunnel will be carried out, that is, Open-hole construction increases the construction length of the open-hole. Using the existing anti-drainage board paving trolley to install open-hole lining steel bars has low construction efficiency and affects the construction progress.
[0004] The existing waterproof and drainage board hanging trolleys generally do not have devices such as steel climbing frames, which cannot complete the climbing of steel bars in one step, seriously affecting the progress of the project, and the efficiency is extremely low

Abstract

The invention relates to the technical field of tunnel waterproof-drainage board paving-hanging, in particular to a tunnel waterproof-drainage board paving-hanging trolley. The tunnel waterproof-drainage board paving-hanging trolley includes a steel bar climbing frame, a walking assembly, a body frame, a telescopic assembly, a nail gun part, and an outer stair platform assembly. The body frame isarranged on the walking assembly, and the steel bar climbing frame, the telescopic assembly, a coil material paving-hanging device and the outer stair platform assembly are arranged on the body frame.

Description

technical field [0001] The invention relates to the technical field of laying and hanging tunnel waterproof and drainage boards, in particular to a trolley for laying and hanging tunnel waterproof and drainage boards. Background technique [0002] In ordinary tunnel construction, the tunnel length is generally between 20.0 and 40.0m, and the open hole lining construction is generally arranged at the end of the tunnel construction period. After the first lining construction of the dark hole is completed, the open hole lining reinforcement is installed by using the waterproof and drainage board hanging trolley, and then the secondary lining concrete construction is carried out. [0003] During the construction of the tunnel, if the condition of the surrounding rock of the tunnel site is found to be poor and does not meet the conditions for the construction of the dark tunnel, in order to ensure the safety of the construction, the weak surrounding rock will generally be excavat...
