Construction method for tunnel continuous mucking, lining and excavation synchronization

Abstract

The invention provides a construction method for the continuous mucking, lining and excavation synchrony of tunnels (caves), which comprises the following steps: the front end of a belt conveyer is positioned in an excavation work area, the belt conveyer from the excavation work area to the lining area of a steel moulding plate trolley is positioned on an inverted arch precast block (6) or hung at the top of the tunnel; the belt conveyer in front of the steel moulding plate trolley causes a conveyer (7) to be positioned at one internal side of a moulding plate trolley gantry (4) when passing through the moulding plate trolley on the basis of being positioned on the inverted arch precast block or a cast-in-situ inverted arch; a falsework (14) is arranged in front of the moulding plate trolley (2) and positioned on a track (12) which is connected in front of the self-circulation of the steel moulding plate trolley; and the belt conveyer is positioned on the inverted arch precast block or hung at the top of the tunnel from a lining operating area to a tunnel entrance after passing through the steel moulding plate trolley. The construction method can realize the continuous mucking of the belt conveyer and the synchronous lining of the moulding plate trolley along with the excavation of the tunnel in tunnel construction and cause transport equipment such as cars or the track to transport facilities and other materials needed by tunnel construction.

Description

technical field [0001] The invention belongs to tunnel (hole) lining and ballasting technology, mainly relates to a tunnel (hole) continuous ballasting, lining and excavation synchronous construction method, in order to solve the existing tunnel (hole) inner lining formwork trolley construction and belt Conveyor ballasting and space interference of transport vehicles. Background technique [0002] At present, the construction methods used in tunnel construction mainly include drilling and blasting method (mine method), TBM method (tunnel tunnel bore drilling machine, referred to as TBM, which is called TBM for hard rock excavation, and shield tunneling for soft rock excavation. Large-scale full-section tunnel construction equipment), shallow burial and underground excavation methods. Regardless of the construction method, the transportation of the excavated dregs can be carried out in any of three ways: automobile transportation, rail transportation, and long-distance conti...

AI Technical Summary

Problems solved by technology

Therefore, in the field of synchronous lining technology, the problem of mutual interference between long-distance continuous belt transportation and steel formwork trolleys has not been resolved.

In the past, a variety of technical solutions for the conveyor belt device to pass through the steel formwork trolley were designed, but none of them were actually adopted because they were not feasible in practice.
