Muck turning and collecting box used for vertical conveying system for ultra-deep shaft construction

Abstract

The invention relates to a muck turning and collecting box used for a vertical conveying system for ultra-deep shaft construction. A housing reinforcement structure is arranged in a muck box housing,four lifting lugs are arranged on the two sides at the upper end of the muck box housing, a bottom door is arranged at the bottom of the muck box housing, and the bottom door is connected with a box bottom opening and closing mechanism. The box bottom opening and closing mechanism comprises a plug, a shaft sleeve, a rotary shaft, a limiting base and an opening-closing base, the bottom door is connected with the muck box housing through the rotary shaft, a horizontal rod of the plug is cooperatively connected with the limiting base which is fixedly arranged on the muck box housing, a vertical rod is connected with the shaft sleeve, the lower end of the vertical rod is fixedly connected with the opening-closing base, and the opening-closing base is driven by a shaft pin to move up and down along the shaft sleeve, so that opening and closing of the bottom door are achieved, and then it is achieved that muck is quickly unloaded. By means of the muck turning and collecting box, quick unloading in the vertical conveying process of the muck from ultra-deep shaft construction is achieved, the risk generated in the vertical conveying process of the muck is effectively reduced, the time formuck unloading is shortened, and the conveying efficiency is improved. Simple human-assisted operation in the unloading site is achieved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a vertical conveying system for deep foundation pit excavation construction, in particular to a slag dumping soil collection box used for the vertical conveying system for extra-deep shaft construction. Background technique [0002] With the deepening of urban underground space development, the demand for sponge city construction is accelerating, and the utilization of shallow underground space is becoming saturated. The development of deep underground space has become an inevitable choice for the construction of coastal central cities. The premise and key to the smooth implementation of deep underground space development is the construction of ultra-deep foundation pits. Ultra-deep foundation pits face problems such as geological conditions, complex water and soil pressure distribution, strong hydrodynamic pressure in deep sand layers, and difficult construction, which pose great challenges to construction equipment, materials...

AI Technical Summary

Problems solved by technology

[0004] During the construction of existing deep foundation pits such as subway working wells, it is necessary to manually go to the construction site to load and unload the muck. However, during the construction process, due to the narrow space, the construction progress is greatly affected, and the safety of slag discharge is poor. Workers The labor intensity is high, and the safety production efficiency is low
