Multi-functional starting and receiving construction operation frame of earth pressure balance shield machine

Abstract

The invention relates to a multi-functional starting and receiving construction operation frame of an earth pressure balance shield machine, and belongs to the technical field of shield construction. The operation frame comprises a frame body, a first folding plate layer, a second folding plate layer, a jumping plate and wheels, wherein the frame body is composed of a circular arch, a first side wall and a second side wall, the first folding plate layer comprises a first front folding plate and a first rear folding plate, the first front folding plate and the first rear folding plate are located on the same horizontal plane when unfolded, the second folding plate layer is installed below the first folding plate layer, and comprises a second front folding plate and a second rear folding plate, the second front folding plate and the second rear folding plate are located on the same horizontal plane when unfolded, the jumping plate is detachably installed on the first folding plate layer and / or the second folding plate layer, and the wheels are installed at the bottom of the frame and slide when the frame body moves. The earth pressure balance shield machine enters and leaves the multi-functional hole construction operation frame to conduct manual hole door chiseling, the time of installing and detaching the operation frame is saved, the time of exposing a hole door soil body is shortened, and the safety risks of constructors for detaching the operation frame are reduced.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to a multifunctional work frame used for starting and receiving construction of an earth pressure balance shield machine. Background technique [0002] With the development of domestic urban rail transit construction, shield construction technology has developed rapidly in our country, and various construction units have also accumulated rich practical experience. However, as the key link of tunnel construction, shield initiation and reception are still the easiest to produce. The place where the problem occurs is also the stage where engineering accidents are most likely to occur. It is directly related to the safety of the construction of the project itself and the surrounding buildings. According to statistics, in the construction of shield tunnels, more than 70% of the construction accidents occurred in the process of shield tunnel initiation and reception, ...
