Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] A shield machine reaction force frame used in tunnel construction, such as figure 1 and figure 2 As shown, it includes a ring-shaped ring body spliced ​​by four arc segments, a steel body outside the ring body, and a support for supporting the back of the steel body. The steel body includes two upright columns 4 and two beams 5, the two ends of the upright columns 4 are integrally formed with plug-in columns 8, and both ends of the beam 5 are provided with slots 9 for plugging and matching with the plug-in columns 8. The post 8 cooperates with the insertion slot 9 to detachably connect the post 4 and the beam 5 together. The end of the plug-in post 8 is provided with rounded corners, which is convenient for inserting the plug-in post 8 into the plug-in slot 9 , thereby speeding up the efficiency of the staff to fix the column 4 on the beam 5 . In t...

Abstract

The invention relates to a shield tunneling machine counter-force frame for tunnel construction. The shield tunneling machine counter-force frame comprises a circular-ring-shaped ring body formed by four arc-shaped sections in a spliced mode, a steel body located outside the ring body, and a supporting piece used for supporting the back face of the steel body; the steel body comprises two verticalcolumns and two crossbeams, inserting columns are arranged at the two ends of the vertical columns, and inserting grooves in inserted fit with the inserting columns are formed in the two ends of thecrossbeams correspondingly; and reinforcing ribs are arranged on the ring body, one ends of the reinforcing ribs are connected with the crossbeams, and the other ends of the reinforcing ribs are connected with the vertical columns. Through cooperation of the inserting columns and the inserting grooves, the vertical columns and the crossbeams are detachably connected together, the inserting columnsare limited in the inserting grooves by the reinforcing ribs, thus the ring body and the steel body are assembled into a whole, and the structural strength and rigidity of the steel body are improvedadvantageously; and meanwhile, the ring body and the steel body are each formed by a plurality of members in a spliced mode, so that mounting construction of the counter-force frame in a tunnel is convenient, the construction work risk is lowered, shield tunneling safety is improved, and mounting, demounting and transporting of the counter-force frame are facilitated.

Description

technical field [0001] The invention relates to the technical field of tunnel shield construction, in particular to a shield machine reaction force frame used in tunnel construction. Background technique [0002] With the development of the economy, shield tunneling has become the main construction method for urban underground rail transit construction and underground space development in soft soil areas in my country. The so-called shield tunneling method refers to the tunnel underground excavation construction method in which shield tunneling machines are used for excavation and reinforced concrete segments are used as lining support. The shield method is used to construct tunnels or various underground pipelines. Generally, the installation, commissioning and trial operation of the shield are carried out in the pre-built working well, and it is accurately placed on the base that conforms to the design axis. After the preparations are ready, start excavation into the form...
