Abstract

The invention discloses a dismantling device for a negative ring segment and a dismantling method of the negative ring segment. The negative ring segment is provided with a bolt connecting hole, the bolt connecting hole penetrates through the position between the inner ring face and the end face of the negative ring segment, the dismantling device for the negative ring segment comprises a bearing plate, an inserting and connecting bent rod and a locking and fixing piece, wherein the supporting plate is provided with an opposite first side and a second side used for being attached to the end face of the negative ring segment, a hoisting lug plate is installed on the first side of the supporting plate, a hoisting hole is formed in the hoisting lug plate, the inserting and connecting bent rod is used for being arranged in the bolt connecting hole in a penetrating mode, the first end of the inserting and connecting bent rod is installed on the second side of the supporting plate, and the locking and fixing piece is used for pressing against the inner ring surface of the negative ring segment and is installed at the second end of the inserting and connecting bent rod. According to the dismantling device for the negative ring segment and the dismantling method of the negative ring segment, the problems that the construction cost is increased due to the prolonged operation period when a traditional negative ring segment is lifted out through a lifting belt, and the consumed time is long are solved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a device for removing a negative ring segment and a removal method thereof. Background technique [0002] After the shield machine is launched successfully, the negative ring segment will be removed in time to facilitate the hoisting and transportation of ordinary segments during normal construction in the starting shaft after the excavation reaches above the hundred rings. [0003] When the negative ring segment is removed, the negative ring segment is generally lifted out by using the negative ring segment sling. This method not only takes a long time, has many uncertain factors, and has a wide range of influence. At the same time, with the operation cycle The extension will also increase the corresponding costs and expenses. Contents of the invention [0004] In order to overcome the defects existing in the prior art, a device for removing the negative ring segment...
