Extension trolley for shield earthwork carrying

Technical Field

The utility model belongs to the technical field of the shield constructs quick-witted technique and specifically relates to a shield constructs extension platform truck for earthwork transport.

Background

The shield starting means that the shield is positioned in an installation shaft or a station-crossing shaft from a shield host, a cutter head is pushed forward to penetrate into surrounding rock and is tunneled forward along a designed line until the shield safely enters a tunnel in an interval, and a tunnel portal reaction frame and a negative ring pipe sheet are dismantled.

The shield originating is divided into an integral originating and a split originating. The integral starting refers to a construction technology that a shield body and all trolleys are arranged under a starting well, and all trolleys are driven to move forward together when the shield starts to drive; the split starting refers to a construction technology that the shield body is connected with all or part of the trolleys by lengthened pipelines, the shield body and all or part of the trolleys move forwards separately, and the shield body and the trolleys are installed and connected in a tunnel after initial tunneling is finished so as to conduct normal tunneling. In which, the whole starting condition of the shield is more and more difficult due to the restriction of narrow construction site, construction condition and other factors in urban area. The split starting is used as a shield starting mode and is widely applied to narrow construction sites in busy cities.

During the split starting stage of the shield, the shield is limited by the structure and the size of the opening, the muck can be transferred only by adopting the small soil bucket at the screw conveyer opening of the shield, the capacity of the small soil bucket is smaller, the muck transportation time is increased, and if the small soil bucket is adopted to transport the muck all the time in the whole shield starting stage, the muck transportation time is greatly increased, so that the tunneling efficiency of the shield is lower, and the split starting progress is influenced.

In contrast, the extension trolley for moving the shield earthwork is used for transporting the muck by using the extension trolley when the shield machine tunnels to the-1 ring in the split starting stage, so that the muck transportation efficiency is improved, and the split starting progress is improved.
