Pipe piece used for shield construction and process for assembling pipe piece into ring

Abstract

The invention discloses a pipe piece used for shield construction and a process for assembling the pipe piece into a ring, belongs to the field of pipe pieces for shield construction, and provides the pipe piece used for shield construction and the process for assembling the pipe piece into the ring. According to the scheme, a ceramic adhesive is used for replacing traditional bolts to carry out fixation on adjacent pipe pieces, every two adjacent pipe piece rings are connected through the bolts, that is, every two adjacent pipe piece rings abut against each other under the action of a shield tunneling machine, excessive connection is not needed to be carried out, in the process that splicing is carried out on the pipe pieces, pressing is carried out on adjacent elastic gaskets by utilizing the weight of concrete slabs, and therefore liquid water and the ceramic adhesive can be rapidly mixed, hardening is carried out to achieve the bonding effect, the working intensity of workers in the shield construction process can be greatly reduced, the workers can carry out long-time construction along with a shield, the single working hour of the workers is increased, and the whole shield construction process is not prone to being affected.

Description

technical field [0001] The invention relates to the field of segment segments for shield tunneling construction, and more specifically, relates to a segment segment for shield tunneling construction and a process for assembling it into a ring. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of shield tunneling is the "shield" (referring to the supporting segment) of the tunnel constructed (laid) by the roadheader while excavating, which is different from the open construction method. [0003] During traditional shield construction, see Figure 9 , every time the shield machine advances 10-15 meters, it will stop, and the prefabricated concrete segments are assembled into rings to construct the supporting segments, and these segments are usually hoisted and installed into rings by hoisting machinery, and then bolts are used to Reinforcement is carried out, and grouting is carried out on the outsid...

AI Technical Summary

Problems solved by technology

[0004] However, during the shield construction process, the working environment provided by the shield workbench is relatively simple. The traditional assembly of concrete segments requires the staff to carry out high-intensity construction, and it is necessary to arrange for the staff to take a break in time, resulting in a single working hour of the staff. Short, easy to affect the overall process of shield tunneling construction and affect the construction efficiency of shield tunneling
