Large-diameter shield tunnel assembly type movable crawling ladder
The invention provides a large-diameter shield tunnel assembly type movable crawling ladder. The large-diameter shield tunnel assembly type movable crawling ladder comprises a box culvert, a tunnel side segment, a crawling ladder, an upper pulley and a lower pulley, wherein the upper section of the crawling ladder is in sliding connection with the top end of the box culvert through the upper pulley, and the lower section of the crawling ladder is in sliding connection with the lower part of the tunnel side segment through the lower pulley. Thus, in the shield tunneling process, when synchronous construction is performed on the rear box culvert part, a worker only needs to apply a little force to the crawling ladder to push the crawling ladder to rapidly move in a tunnel, so that the problem that the shield tunneling machine worker need to replace the crawling ladder when synchronous construction is performed from the upper end of the box culvert to the lower end of the box culvert in the shield tunneling machine tunneling process is effectively solved; and the large-diameter shield tunnel assembly type movable crawling ladder has the advantages of simple materials and structure and easiness in manufacturing, the construction efficiency is improved, standardized construction of engineering construction is embodied, and good social benefits are generated.
本发明提供一种大直径盾构隧道组装式移动爬梯，其包括箱涵和隧道侧管片，还包括爬梯、上部滑轮和下部滑轮，所述爬梯的上段通过上部滑轮与箱涵的顶端滑动连接，所述爬梯的下段通过下部滑轮与隧道侧管片的下部滑动连接。这样在盾构掘进过程中，后面箱涵部分进行同步施工时，工作人员只需对爬梯施加一点力即可推动爬梯在隧道内快速地移动位置，从而有效解决了盾构机掘进过程中盾构机人员在从箱涵上端通往下端进行同步施工时需更换爬梯的问题，且本发明的材料、结构简单，易制作，提高施工效率，体现工程施工标准化建设，产生较好的社会效益。
