Shield tunnel grouting trolley

Abstract

The invention provides a shield tunnel grouting trolley, and belongs to the technical field of shield construction equipment. The shield tunnel grouting trolley comprises a trolley body, a grouting mechanism, a grouting pipe plug-pull mechanism, a leaked grout cleaning mechanism and a waste dumping mechanism, a door opening for allowing a transport trolley to pass through is arranged at the middlepart of the trolley body, and the trolley body is used for traveling along a tunnel; the grouting mechanism is arranged on the trolley body and used for grouting the tunnel through a grouting pipe; the grouting pipe plug-pull mechanism is arranged on the trolley body and used for plugging the grouting pipe into and pulling the grouting pipe from the side wall of the tunnel; the leaked grout cleaning mechanism is arranged on the trolley body and used for cleaning the grout leaking from the side wall of the tunnel; and the waste dumping mechanism is arranged on the trolley body and used for dumping waste to the passing transport trolley. By adopting the shield tunnel grouting trolley provided by the invention, waste can be handled simply and conveniently, and the whole process can be operated by a small number of workers, which is beneficial to saving manpower and improving grouting efficiency, and at the same time, a decrease in the cleanliness of a working surface caused by the outflow of grout can be avoided and the improvement on construction safety can be facilitated.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling equipment, and more specifically relates to a shield tunnel grouting trolley. Background technique [0002] Shield method tunnel construction refers to the use of shield machine to control the excavation surface and surrounding rock from collapse and instability while carrying out tunnel excavation and slag removal, and assembling segments in the machine to form lining and implement grouting behind the wall. A method of building a tunnel by disturbing the surrounding rock. Since there are pre-set grouting holes on the segments, grouting is usually carried out by manually installing grouting pipes on the grouting trolley, which not only consumes manpower, but also has low efficiency, and some grouting holes or Slurry leakage often occurs in joints and other parts of the segment. The leaked slurry flowing on the segment will reduce the cleanliness of the working surface and easily cause pe...
