Concrete transporting method used for small-diameter tunnel of narrow working well

Abstract

The invention discloses a concrete transporting method used for a small-diameter tunnel of a narrow working well. The concrete transporting method used for the small-diameter tunnel of the narrow working well comprises the following use steps of S1, laying a tunnel internal track in a central axis position of the small-diameter tunnel; S2, mounting a translation shuttle bus in the narrow working well; S3, hoisting two transporting small tank cars to a translation shuttle bus transverse moving track and enabling the transporting small tank car placed on a tunnel internal track docking track toreceive materials first; S4, when the No. 1 transporting small tank car performs pouring in the small-diameter tunnel, arranging the No. 2 transporting small tank car in a vertical shaft to receive the materials; S5, after the materials of the No. 1 transporting small tank car come out of a hole, starting the translation shuttle bus so that the No. 2 transporting small tank car translates along the No. 2 transporting small tank car transverse moving track till finishing docking with the tunnel internal track; enabling the No. 2 transporting small tank car to run to a pouring point in the small-diameter tunnel to begin to pour again; and enabling the No. 2 transporting small tank car to alternately perform concrete pouring. The concrete transporting method used for the small-diameter tunnelof the narrow working well has the advantages that efficient concrete transportation of the small-diameter tunnel under the narrow working well condition can be realized, the construction continuityand construction quality can be guaranteed, and the construction efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a concrete transportation method for small-diameter tunnels in narrow working shafts. Background technique [0002] With the needs of social development and the progress of construction technology, the number of small-diameter and long-distance tunnels is increasing, and during the construction process, shafts are set smaller due to functional and land restrictions. During the construction of the second lining of the tunnel, if the concrete needs to be transported to the pouring point for pouring, due to the size of the tunnel, double rails cannot be laid in the tunnel, and turnouts cannot be laid in the shaft, and the concrete can only be transported by a single tank truck, which is extremely inefficient; Although the construction efficiency can be improved by directly pumping the concrete to the pouring point in the country, due to the limitation of the process, the...
