Abstract

The invention discloses an umbrella-shaped expansion device for opening an umbrella by collision and a re-opening method thereof, the umbrella-shaped expansion device comprises an umbrella-shaped expansion device with a rib pulling disc, an umbrella-shaped folding rod group and a rib penetrating disc, and the umbrella-shaped expansion device further comprises a collision pestle, and the collision pestle is arranged at the front end of the umbrella-shaped expansion device; when the umbrella-shaped folding rod set is folded in the forward direction, the rear end of the abutting pestle is fixedly connected with the tendon pulling disc. When the umbrella-shaped folding rod set is folded reversely, the rear end of the abutting pestle movably penetrates through the rib pulling disc and is fixedly connected with the rib penetrating disc. The abutting pestle is used for making contact with the hole wall in front of the drilling hole expanding section. The invention aims to provide the umbrella-shaped expanding body equipment for opening the umbrella by collision and the re-opening method of the umbrella-shaped expanding body equipment, so as to solve the problem that the umbrella opening mode is tedious and time-consuming in the prior art, and achieve the purposes of greatly simplifying the umbrella opening mechanism and simplifying the umbrella opening steps.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to an umbrella-shaped expansion device and an expansion method for colliding and opening an umbrella. Background technique [0002] The umbrella-shaped expansion device involves the field of geotechnical engineering, and is specifically used in temporary foundation pit support and permanent slope support in various industries such as housing construction, highways, railways and urban rails, water conservancy and hydropower, civil air defense, underground engineering, and national defense. , Anti-floating anchor rod and anchor cable, tunnel vault support. [0003] In the traditional anchor cable construction, the anchor cable is usually placed by manual anchor delivery. Other mechanical placement methods include professional cable delivery machines, anchor drilling rigs, rotary spraying machines or hoisting machinery. The inventors of the present application have studied and s...
