Abstract

The invention discloses a reaction force frame for a shield machine to originate on a small radius curve. The reaction force frame for the shield machine to originate on the small radius curve comprises a reaction force frame body and pre-buried parts arranged along the two sides and the bottom of the reaction force frame body and capable of fixing the reaction force frame body to an opening, and reinforcing bars are arranged on the side, close to the small radius curve, of the reaction force frame body. The reaction force frame for the shield machine to originate on the small radius curve has the characteristics of being convenient to construct, safe, reliable and economical, and can be widely applied in the field of tunnel construction.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a reaction force frame used for starting a shield machine on a small-radius curve. Background technique [0002] In previous shield tunneling constructions, shield tunneling started on a straight line or on a curve with a large radius, and the left and right columns of the starting reaction frame were arranged symmetrically. However, in a specific project, since the shield machine starts on a small-radius curve, the opening has a certain angle, resulting in uneven force on the column of the reaction frame on one side, and the structure of the reaction frame may be damaged , thus delaying the project, so it is necessary to find new work ideas in the project for reference. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned background technology, and provide a reaction force frame for the shield machine...
