Abstract

The invention relates to the field of concrete engineering, in particular to a concrete injection pipe guiding auxiliary frame for vertical shaft construction. The concrete injection pipe guiding auxiliary frame comprises a bottom ring, a bracket, a rotating gear, a movable adjusting assembly and the like; and three supports are arranged on the bottom ring, the rotating gear is jointly connected among the three supports in a sliding manner, and the movable adjusting assembly is arranged on the rotating gear. Through cooperation of a rotation gear and the rotating gear and devices on the rotating gear, the rotation gear can drive the rotating gear and the devices on the rotating gear to reverse by a certain angle, so that the concrete spraying position of a hollow pipe can be replaced, a baffle is prevented from toppling over, and quantitative concrete can be conveniently sprayed to the next position between the inner wall of a vertical shaft and the baffle through the hollow pipe; and the concrete can be uniformly sprayed on the inner wall of the vertical shaft through the hollow pipe in such a reciprocating manner, so that the effect that the concrete can be uniformly sprayed on the inner wall of the vertical shaft to ensure the stability of the vertical shaft is achieved.

Description

technical field [0001] The invention relates to the field of concrete engineering, in particular to a concrete injection pipe guiding auxiliary frame for shaft construction. Background technique [0002] In the process of underground tunnel construction, in order to facilitate the transportation of materials between the underground tunnel and the ground, shafts are usually set up at equal intervals on the ground along the underground tunnel. To maintain the stability of the shaft, it is necessary to open a hole on the inner wall of the shaft. After injecting concrete into the hole, quickly insert the anchor rod into the hole, and then lay a reinforcement cage on the inner wall of the shaft, and fix the reinforcement cage with the anchor rod. Concrete shotcrete is sprayed on the inner wall of the shaft of the shotcrete cabinet. [0003] In the existing process of spraying concrete on the inner wall of the shaft using a concrete jetting machine, it is necessary to manually gu...
