Grouting device for tunnel construction

Abstract

The related utility model relates to the technical field of construction. The related utility model particularly provides an grouting device for tunnel construction, which consists of a movable base (1); the upper part of the movable base (1) is equipped with an grout storage container (6), a pump body (2) and a support frame (21); the inlet end of the pump body (2) communicates with the grout storage container (6); the upper part of the support frame (21) is fixedly connected to two support sleeves (18); the rotary drum (5) is inserted through the two support sleeves (18); the left side of the rotary drum (5) is equipped with a lining pipe (4) via a bearing; the upper part of the movable base (1) is equipped with a first support plate (3) and a second support plate (17); the left end of the lining pipe (4) passes through the first support plate (3) and communicates with the outlet end of the pump body (2); the injection hose (19) is provided for communication with the rotary drum (5) and is wound around the rotary drum (5); and the elbow pipe (20) is located inside the housing tube (4) and is in communication with the grouting hose (19). The present utility model enables grouting operations to be performed via the grouting hose (19), the length of which can be adjusted. Workers do not need to move the grouting device frequently during grouting operations, that is, workers can simply hold the grouting nozzle (11) and adjust the grouting location as desired. This increases work efficiency and shows great practicality.
