Construction method of secondary lining for inclined well with sharp slope

Abstract

The invention provides a construction method of a secondary lining for an inclined well with a sharp slope, which comprises the following steps: S1) excavating the inclined well to a predetermined depth to form the face of the tunnel face of the inclined well; S2) determining the starting position of the initial lining according to the current excavation position of the tunnel face of the inclinedwell; S3) during the excavation of the inclined well, carrying out the sectional secondary lining construction between the starting position of the initial lining and the wellhead position of the inclined well; S4) according to the current excavation position of the tunnel face of the inclined well, determining the starting lining position; S5) lowing a lining trolley to the starting lining position through a tractor and a pusher; S6) carrying out the sectional secondary lining construction between the starting lining position and the completed position of the previous sectional secondary lining construction; S7) cyclically executing S4 to S6 until the completion of the second lining construction of the inclined well. The method can shorten construction period, save construction costs andreduce the occupation of the well opening.

Description

technical field [0001] The invention relates to the field of municipal engineering construction, in particular to a secondary lining construction method for a large-slope inclined shaft. Background technique [0002] A large number of tunnel projects have been built in traffic projects such as railways and highways in my country. In order to speed up the construction progress of long and extra-long tunnels and shorten the construction period, inclined shafts with inclined angles are often set up in combination with terrain conditions, and long and extra-long tunnels are divided into multiple constructions. section to increase the working face of long and extra-long tunnels. [0003] Due to the large slope of the inclined shaft and the heavy weight of the lining trolley, during the secondary lining construction of the inclined shaft, it is necessary to install a winch at the entrance of the inclined shaft after the excavation of the inclined shaft is completed, and the lining ...
