Movable electric control shield launching device and control method thereof

Abstract

According to the movable electric control shield launching device and the control method thereof, compared with an existing shield launching method, a rail platform is arranged on a guide rail, a counter-force frame is fixed to the rail platform, and the position of the counter-force frame can be changed at will by moving and fixing the rail platform. When shield launching is carried out, the launching base, the counter-force frame, the rail platform and the guide rail form a whole to provide reverse thrust for the shield tunneling machine, a jack of the shield tunneling machine acts on the counter-force frame, the shield tunneling machine moves forwards through the reverse thrust, the counter-force frame moves forwards along the guide rail in a stepping mode according to forward movement of the shield tunneling machine, and the steps are repeated till shield launching is completed. By means of the method, the process of assembling and disassembling the multi-ring negative-ring duct piece is omitted, the shield tunneling machine can automatically complete launching, the construction cost is reduced, the construction period is shortened, and the construction risk is reduced.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for shield machines, in particular to a movable electric control shield starting device and a control method thereof. Background technique [0002] The shield initiation stage restricts the entire shield tunnel project. Among the devices required for shield starting, the shield starting frame has a steel structure, a reinforced concrete structure and a combination of the two. It is installed on the starting axis to support the shield host, providing it with a working platform and certain constraints. The steel structure is often used for the reaction frame, which provides reaction force for the shield host when starting; when the shield starts, a negative ring segment is installed between the shield tail and the reaction frame to provide thrust for the shield machine. The design and installation of the starting frame, the reaction frame and the negative ring segment are one of the ke...
