Abstract

The invention provides a tunnel boring machining (TBM) excavating tunnel rail type wet spraying concrete lining combined trolley. The TBM excavating tunnel rail type wet spraying concrete lining combined trolley comprises an equipment trolley and a working trolley which are connected with each other. Walking wheel boxes are arranged at the bottom of the equipment trolley and the bottom of the working trolley and walk along a trolley rail. In the equipment trolley, one side of an equipment trolley frame is provided with a concrete stirring platform used for placing a concrete stirring transportation tank; the concrete stirring platform is provided with a wet spraying concrete pump and an admixture stirring pumping mechanism; the other side of the equipment trolley frame is provided with a generator platform used for placing a diesel generator and an air compressor; the top of the equipment trolley is provided with a transportation tank lifting device; and the bottom of the equipment trolley and the bottom of the working trolley are provided with trolley internal gaps for allowing an internal combustion locomotive flat plate and the concrete stirring transportation tank to pass. The TBM excavating tunnel rail type wet spraying concrete lining combined trolley has the functions of providing electric power and compressed air, can meet the requirement for continuously conducting tunnel rock wall wet spraying concrete lining construction along a tunnel and has a platform space for allowing construction personnel to conduct operating.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment, in particular to a TBM excavation tunnel rail-type wet sprayed concrete lining combination trolley for excavating long-distance and large-diameter tunnel wet sprayed concrete linings by TBM. Background technique [0002] At present, in the excavation of long-distance and large-diameter tunnels in medium-hard rock and hard rock formations, open-type full-face hard-rock tunnel boring machines, referred to as TBM (Tunnel Boring Maching) are used for tunneling construction. In order to cooperate with the rock wall of the tunnel excavated by the TBM, various construction machines and tools supporting the TBM were installed. Lay the diesel locomotive track at the bottom of the rock wall, erect the steel rail on the steel sleeper of the diesel locomotive track, and lay the temporary walking track for the supporting trolley after the TBM, that is, the equipment trolley track. [0003] A proj...
