Power external dredging equipment and working method for small-diameter drainage blind pipes in tunnels

Abstract

The invention discloses a power external dredging device and a working method for small-diameter drainage blind pipes in tunnels, including a rotary drive device, the power output end of the rotary drive device is connected with a vibration cutting mechanism through a power transmission mechanism, and the power transmission mechanism is put on the A sliding tube and a fixed tube are provided, one end of the sliding tube is connected with the rotary drive device, the other end of the sliding tube extends into the fixed tube and is slidably connected with the fixed tube, and the vibrating cutting mechanism extends out of the fixed tube; the power transmission mechanism includes several sequentially connected The universal joint connected with the shaft, the universal joint at one end of the power transmission mechanism is connected with the rotary driving device, and the universal joint at the other end is connected with the mounting column of the cutting bit seat; the rotating sleeves on several connecting shafts are provided with supporting parts, and several supporting parts are connected with the The corresponding sliding tube is in contact with the inner wall of the fixed tube. The invention can quickly and conveniently clear the clogging problem of small-diameter blind drainage pipes by means of mechanical cutting and vibration.

Description

technical field [0001] The invention belongs to the technical field of dredging blind drainage pipes of traffic tunnels, and in particular relates to a powered external dredging device and a working method for small-diameter drainage blind pipes of tunnels. Background technique [0002] In recent years, with the rapid development of the construction of highway tunnels, railway tunnels, subway tunnels and municipal pipe galleries in China, the status of the drainage system has become increasingly important. As important components of the drainage system, drainage blind pipes and drainage ditches are directly related to their blocking status. It is related to the service performance of the drainage system. [0003] In these tunnel projects, the problem of crystallization blockage of tunnel drainage blind pipes is relatively common during the operation of tunnels, especially in karst area tunnels. In severe cases, it can lead to increased leakage of tunnel water, increased lini...
