斜井盾构地下可拆解刀盘结构设计

Design of the Disassembly Cutter Structure and Dismantling Technology for Shield Machine Underground in Inclined Shaft

盾构斜井地下拆解受空间及地质条件等多方因素的影响,无法直接进行刀盘吊装拆解。为实现盾构刀盘在斜井地下有限空间内安全、快速、高效拆解,必须开展盾构刀盘可拆解结构形式研究。在盾构研发设计阶段,结合盾构施工斜井工程设备要求和盾构地下拆解施工条件,将刀盘分块设计理念植入到盾构刀盘结构设计中,对盾构刀盘的重量、结构尺寸等关键可拆解结构参数进行分析设计。

Shield inclined shaft underground dismantling ＇affected space and geological conditions and other factors. It cannot directly carry out the dismantling of cutter. In order to realize the shield safety, in inclined underground space is limited in rapid and efficient dismantling, research on cutter structure type of shield can be carried out. Therefore, according to the construction of inclined shaft engineering equipment and shield underground dismantling construction conditions, the design concept of the cutter block is embedded in the shield cutter structure design in the research and design phase of the structure are studied in this paper. shield, and the weight and size of dismantling cutter
