【摘要】：以引松工程為背景,結(jié)合TBM施工前的基建要求,詳細介紹開敞式TBM滑板式步進機構(gòu)的組成、步進原理,并概述滑板式步進技術(shù)對步進洞、始發(fā)洞、不良地質(zhì)預(yù)處理段步進洞、檢修洞的建造要求。最后,根據(jù)實際應(yīng)用情況對滑板式步進技術(shù)始發(fā)和接收的操作流程、步進過程中的注意事項、出現(xiàn)的問題及步進效果進行總結(jié),并結(jié)合基建要求對該種步進機構(gòu)的優(yōu)缺點進行闡述,可為類似TBM工程的前期基建及步進作業(yè)提供參考。
[Abstract]:Based on the background of lead-loose project and the requirement of construction before TBM construction, the composition and principle of open-type TBM slide-plate stepping mechanism are introduced in detail, and the sliding-plate step-by-step technology for step-in-hole, initial hole and bad geological pre-treatment section is described in detail. The construction requirements for the inspection and repair of holes. Finally, according to the actual application, this paper summarizes the starting and receiving operation flow of slide-plate stepping technology, the matters needing attention in the stepping process, the problems that appear and the effect of step-by-step. The advantages and disadvantages of this kind of stepping mechanism are expounded in combination with the requirements of capital construction, which can be used as a reference for the pre-construction and stepping operation of similar TBM projects.
