Tunnel self-advancing support shed

Abstract

The invention discloses a tunnel self-advancing support shed which comprises a front arch frame, a rear arch frame, an advancing jack and supporting jacks, wherein the front arch frame comprises more than three front longitudinal beams and more than three front arch beams, all front longitudinal beams are longitudinally arranged along the arch upper surfaces of the front arch beams, each front longitudinal beam is connected with all the front arch beams, and one supporting jack is arranged under the front arch frame; the rear arch frame comprises more than three rear longitudinal beams and more than three rear arch beams, all rear longitudinal beams are longitudinally arranged along the arch upper surfaces of the rear arch beams, each rear longitudinal beam is connected with all the rear arch beams, and the other supporting jack is arranged under the rear arch frame; the front longitudinal beams and the rear longitudinal beams are arranged at intervals, and a spacing distance is arranged between a front arch beam and an adjacent rear arch beam in the front; and one end of the advancing jack is connected with the front arch frame, the other end of the advancing jack is connected with the rear arch frame, and the front arch beams and the rear arch beams are all arch beams. With the adoption of the tunnel self-advancing support shed, time and labor are saved, and safety and reliability are realized.

Description

technical field [0001] The invention relates to the fields of traffic, water conservancy, and municipal tunnel excavation engineering, in particular to a tunnel self-moving support shed. Background technique [0002] In the prior art, shield machines are used to excavate engineering tunnels, but due to various conditions, in the construction of mountain tunnels, blasting construction and conventional support methods are mainly used. [0003] The supporting equipment used in known arched tunnels has steel arches, and the steel arches are circular steel pipes or I-beams bent into arches one by one. to support surrounding rock. There is also a steel pipe with a length of 10 to 45 meters used longitudinally. This steel pipe is arranged in an arched manner on three sides of the surrounding rock, called a pipe shed, which can play the role of advanced support. There are also many support methods such as anchor rods and wooden sheds. [0004] In the process of realizing the pres...
