Controllable roof supporting system for dangerous rock masses in cavern and using method thereof

Abstract

The invention belongs to the technical field of cavern support, and particularly discloses a controllable roof supporting system for dangerous rock masses in a cavern and a using method thereof. The controllable roof supporting system for the dangerous rock masses in the cavern includes a main supporting system and an auxiliary supporting system, wherein the lower end of the main supporting systemis placed on the ground in the cavern, the top of the main supporting system is driven to controllably support the dangerous rock masses in the cavern by adjusting a controllable jacking component arranged in the middle, the lower end of the auxiliary supporting system is connected to the main supporting system, the top of the auxiliary supporting system is controlled by an auxiliary jacking screw to support the dangerous rock masses in the cavern, and thus the dangerous rock masses at the top in the cavern can be supported point by point to form a network point-like support. The whole support system can be assembled and disassembled in a modularized mode, the assembly is convenient, supporting is effective, construction has little influence on the cavern, the controllable jacking component is adopted to cooperate with the auxiliary jacking screw for controllable contact support of each contacted dangerous rock mass, the whole support process is controllable, the support effect is remarkable, and the cost is relatively low.

Description

technical field [0001] The invention belongs to the technical field of cavern support, and in particular relates to a controllable roof support system for dangerous rock mass in caverns and an application method thereof. Background technique [0002] Cavern support operations are widely used in geotechnical engineering fields at home and abroad; common roof support methods are roof anchor cable hanging net support, roof advance grouting support, prefabricated masonry support, steel or concrete beam column support protection in many ways. Traditional support operations are widely used in tunnels, roadways, and underground engineering, but most of them require drilling and surface spraying of rock and soil, and most of them cannot adapt to the point-contact combination of roofs with large height differences in small chambers. protection. my country is a large country of stone cultural relics, and the preservation of stone cultural relics represents the development level of c...
