Abstract

The invention discloses a combined type steel pipe sheet of a connection channel at the position of a joint with a main tunnel and a construction method. The connection channel at the position of thejoint with the main tunnel adopts a combined steel pipe sheet, the combined type steel pipe sheet is that each steel pipe sheet is arranged to be two parts according to radian split bodies of the maintunnel at the corresponding circumferential positions, one part is a fixing pipe segment located in the connection channel, and the other part is a temporary pipe segment needing to be dismounted. Dismounting and mounting of the fixing pipe segment and the temporary pipe segment are achieved by utilizing direct bolts. The combined steel pipe sheet is adopted, dismounting and mounting are achievedthrough the direct bolts, cutting at a site is not needed any longer, the on-situ construction efficiency is improved greatly, and it is greatly beneficial for ensuring the project quality.

Description

technical field [0001] The invention relates to a steel pipe sheet of a communication channel used at a position connecting with a main tunnel in the construction of a communication channel by a shield method and a construction method thereof. Background technique [0002] In the invention patent application document with the application publication number CN106948833A, an "assembled communication channel structure and construction method" is disclosed. Steel pipe sheets are used such as Figure 4a In the shown structural shape, each steel pipe sheet is a conventional cylindrical steel pipe sheet 11 with the same structure, and the whole circumference is a cylindrical pipe after assembling. The structural form at the joint position; in order to prevent the structure of the connecting passage 22 from invading the boundary of the main tunnel, after the excavation of the connecting passage 22 is completed, it is necessary to cut off the part of the connection between the main t...
