With the development of economy, land resources tend to be tense. Civil engineering works, particularly those in busy places in cities, are beginning to develop and utilize underground spaces on a large scale. At present, building structures in China, particularly commercial building structures, are generally provided with one-layer or two-layer basements. Some large building structures even comprise three-layer or four-layer basements, and the excavation depth of foundation pits of the large building structures reaches below 16 m. Meanwhile, with the development of rail transit in recent years, excavation of foundation pits of subway stations is more and more common, and the excavation depth of the foundation pits of the subway stations generally exceeds 20 m. The foundation pit engineering construction has certain danger, and the larger the excavation depth of the foundation pit is, the higher the danger degree is. Once major safety accidents of foundation pit engineering occur, the casualty number of construction operators is often very large. In order to ensure the personal safety of construction operators, according to the safety production policy of 'safety first, prevention first' and 'emergency first', not only the prevention in advance is achieved, but also emergency safety measures after accidents occur are required to be made. Therefore, measures for ensuring that construction operators evacuate timely after a foundation pit accident occurs are very important.
At present, once an emergency safety accident occurs in the foundation pit construction process, construction operators generally escape from the foundation pit by using an escape rope ladder. The traditional escape rope ladder is composed of two steel wire ropes in the vertical direction and a plurality of square wood transverse partitions in the horizontal direction, wherein the steel wire ropes are generally composed of galvanized wire rope penetrating cores with the diameter of 6mm in the center and nylon ropes with the diameter of 18mm outside, and the top ends of the steel wire ropes are bound on a compression head beam of a foundation pit.
