Abstract

The invention provides a climbing ladder, which comprises a ladder body and a protective fence, wherein the protective fence is arranged around the ladder body, so that the protective fence can achieve a protection effect on the ladder body arranged inside the protective fence; and when workers climb up or climb down by using the climbing ladder, the workers can be enabled not to be injured by other objects in the climbing-up and climbing-down process. The climbing ladder solves the problem that the workers can easily get injured in the well entering or well going-out process in the prior art.

Description

technical field [0001] The invention relates to the field of shield well construction, in particular to a climbing ladder. Background technique [0002] At present, the power transmission project is constructed using a new technology - the shield tunneling method. Before the tunnel construction, a shield tunneling shaft should be built first, and a shield tunneling shaft should be built after completion. [0003] However, since the staff frequently go up and down during the construction of the shield well, and it is also difficult to install climbing ladders in the well, it is difficult for the staff to go up and down in the well, which makes the construction efficiency of the shield well low and the staff's Personal safety cannot be guaranteed. [0004] In addition, the climbing ladders in the prior art are open and relatively leak-proof, which cannot guarantee that the staff will not be hurt by other objects during the process of going up and down. Contents of the inven...
