Abstract

The invention discloses a tunnel coring device which comprises a hand-cranking device, a fixed pulley, a coring device body, a connecting rope and a blade set. The hand-cranking device and the fixed pulley are arranged at the first end of the coring device body. The blade set is arranged at the second end of the coring device body, the connecting rope penetrates through the coring device body, oneend of the connecting rope is wound around the fixed pulley, and the other end of the connecting rope is connected with the blade set. The hand-cranking device is used for rotating the fixed pulley,and the connecting rope is used for controlling the blade set to contract. The tunnel coring device aims to solve the problems that an existing tunnel coring device is single in function, low in coring speed and poor in coring effect.

Description

technical field [0001] The invention belongs to the technical field of engineering equipment, and in particular relates to a tunnel corer. Background technique [0002] Most of the tunnels in the new high-speed railway projects in the northern region are loess tunnels in terms of geology. In order to prevent problems such as arching and sinking of the line in the later operation process, there are certain requirements for the construction technology and construction method of the tunnel inverted arch construction. In addition, an effective way to detect inverted arches is to drill core samples to check thickness, strength, and delamination positions. The diameter of the drilled core sample is 10cm, and the length is from the top surface of the filling to the bottom of the inverted arch according to the design. In the core sample, because the joint of two different grades of concrete poured in layers is the weakest, it is easy to break during the process of extracting the co...
