Abstract

The invention discloses a construction method and device for detaching partial segments in a limited space. A portal frame is installed outside the partial segments, multiple chain blocks are installed on the portal frame, and the multiple chain blocks comprise a first chain block located in the middle of the portal frame and the second chain blocks located on the two sides of the first chain block. Rails are arranged in the multiple rings of partial segments in the longitudinal direction of the partial segments and allow a transportation vehicle to operate. By the adoption of the constructionmethod and device for detaching the partial segments in the limited space, the partial segments can be sequentially hoisted and detached, the transportation vehicle can conveniently transport the segments to a well mouth, and then a portal crane hoists the segments and places the segments on a segment site. The construction method and device for detaching the partial segments in the limited space have the advantages of safety, reliability, convenient operation, a simple structure and the like; the detachment construction safety of the partial segments is guaranteed, and the problem of detaching the partial segments in underground excavation limited space is effectively solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method and device for removing a negative ring in a limited space. Background technique [0002] With the large-scale development of domestic subway construction, the shield construction method is widely used in the construction of subway sections due to its characteristics of safety, speed, and wide adaptability. In the construction process of urban subway interval tunnels, the traditional negative ring demolition method is to remove the negative ring segments with the help of ground cranes and direct lifting of the negative ring segments. Convenience, many safety factors and other difficulties make it impossible to use a crane for direct removal. Therefore, there is an urgent need for a construction method that can facilitate the removal of negative ring segments in a limited space. Contents of the invention [0003] The purpose of the present in...
