Problems solved by technology

However, the concrete segment will be scrapped after use, and the reuse rate is low, resulting in a great waste of resources and environmental pollution.
There are no specific and complete measures that can solve the problem in the existing methods

Embodiment Construction

[0041] In order to understand the technical content of the present invention more clearly, the following examples are given in detail. In this embodiment, the installation of nine steel pipe negative rings 1 is taken as an example, and the shield machine 26 (Komatsu 6760mm earth pressure balance shield machine of Japan) is used for installation.

[0042] See figure 1 As shown, in step (1), the steel pipe sheet 2 required by the project is manufactured.

[0043] According to engineering needs, use steel to make steel pipe sheet 2: bottom steel pipe sheet 3, left lower steel pipe sheet 4, left upper steel pipe sheet 5, top steel pipe sheet 6, right upper steel pipe sheet 7 and right lower steel pipe sheet 8 (see Figure 5 shown). During the manufacturing process, the steel pipe sheet 2 is protected by spraying paint to reduce corrosion damage during use.

[0044] Step (2), assembling and using steel pipe sheet negative ring 1, wherein:

[0045] Step (21), such as figure 2 ...

Abstract

The invention provides a minus-circled flake construction method for shield tunnel construction. Minus-circled flakes which are used are steel segment minus-circled flakes. Preferably, the minus-circled flake construction method for shield tunnel construction particularly comprises the following steps that (1), steel segments are manufactured; (2), the steel segments are used for splicing the steel segment minus-circled flakes and the steel segment minus-circled flakes are used for building a shield launching thrust counter-force foundation; and (3), the steel segments are dismounted from the shield launching thrust counter-force foundation and then are stored. The steel segments comprise the bottom steel segment, the lower left steel segment, the upper left steel segment, the top steel segment, the upper right steel segment and the lower right steel segment. Except for the final steel segment minus-circled flake, only lower half rings of other steel segment minus-circled flakes are spliced. The minus-circled flake segments used in the minus-circled flake construction method for shield tunnel construction are not scrapped after being used, the repeating utilization rate is high, resources are saved, environmental pollution is avoided, design is ingenious, operation is easy and convenient, cost is low, and the method is suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to the technical field of tunnel construction, in particular to a negative ring construction method for shield tunnel construction. Background technique [0002] With the rapid development of urban municipal construction and rail transit, the underground space has been continuously developed and utilized, and the shield tunneling method is more and more widely used in the construction of subway tunnels. The amount of negative ring used in shield tunnel construction is also getting larger, and the use of negative loops is necessary. [0003] In the existing construction method, the negative ring is mainly made of concrete segments. A concrete segment negative ring usually includes 6 concrete segments, namely the bottom concrete segment, the lower left concrete segment, the upper left concrete segment, and the top concrete segment. The segments, the upper right concrete...
