Abstract

The invention relates to a method for using a claw-type double-cavity three-section tunnel dredger, which includes a tubular rotating part and a grabbing and digging part connected together in sequence; The hollow cylinder powered by the bending joint, the second bending joint, and the third bending joint; the inside is also provided with a control device for controlling the curvature of the first bending joint, the second bending joint, and the third bending joint. The grabbing part is a plurality of finger-shaped claws arranged in the circumferential direction, with an elliptical cross-section, and a cross-section close to the tubular rotating part that is larger than a cross-section away from the tubular rotating part. Each finger-shaped claw is provided with 3 A bending joint that moves radially towards the circle formed by the finger-shaped claws. The first bending joint is set at the connection between the top of the tubular rotating part and the finger-shaped claw, that is, the root of the finger-shaped claw, and the second bending joint is set at the finger-shaped joint. In the middle part of the claw piece, the third bending joint is arranged at the head of the finger-shaped claw piece.

Description

technical field [0001] The invention relates to a method for using a claw-type double-cavity and three-section tunnel dredger. Background technique [0002] At present, dredgers for large tunnels usually use shield machines, but they are expensive. Therefore, dredgers with similar design functions to shield machines are needed, but cheap. Contents of the invention [0003] In view of this, in order to solve the above problems, the present invention provides a method for using a claw-type double-chamber three-section tunnel dredger. [0004] The method of using the claw-type double-chamber three-section tunnel dredger includes tubular rotating parts and grabbing parts that are connected together in sequence; The hollow cylinder that provides power for the joint and the third bending joint; the control device for controlling the curvature of the first bending joint, the second bending joint and the third bending joint is also arranged inside. [0005] The grabbing part is ...
