摘要
Abstract
In tunnel excavation of Neelum-Jhelum Hydroelectric Project by TBM, the clamp cylinder of TBM bracket boots was damaged. On the basis of analyzing the structural composition and working principle of TBM bracket boots, the bracket boot boots was disassembled and checked. It was found that the damage was mainly caused by the large angle deflection of the bracket boots, which made the clamp cylinder directly press on the cylinder bottom, resulting the inner screw thread pressed. Due to the shortage of the cylinder parts in construction site, unconventional repair mode was proposed by considering the whole project schedule. The arrangement of clamp cylinders less than normal numbers was introduced. The tunnling effect shows that the need for the angle adjustment can be guaranteed with the clamp cylinder reasonably arranged. The experience can be used for the re-pair work of similar engineering construction equipment.关键词
