Large-slope inclined well concrete transportation method

Abstract

The invention discloses a large-slope inclined well concrete transportation method which comprises the following steps of building a concrete mixing plant; equipping with a ground concrete stirring transportation tank car; pouring a hole concrete unloading platform; laying rails, putting a wheel-rail concrete stirring transportation tank car on the rails, and dragging the wheel-rail concrete stirring transportation tank car with a single-rope mine drum hoist arranged at an inclined well hole; pouring a hole bottom concrete unloading platform, and equipping with a hole bottom concrete stirringtransportation tank car; transporting concrete in the concrete mixing plant to the hole concrete unloading platform with the ground concrete stirring transportation tank car; transporting the concreteinto the wheel-rail concrete stirring transportation tank car; transporting the concrete in the wheel-rail concrete stirring transportation tank car into the hole bottom concrete stirring transportation tank car; transporting the concrete in the hole bottom concrete stirring transportation tank car to a pouring site in a main hole and the like. The large-slope inclined well concrete transportation method can realize the targets of rapidness in transportation and safety in construction of inclined well concrete, ensures main hole lining concrete construction, reduces construction interferenceand lowers the construction cost.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a method for transporting concrete in a large-slope inclined shaft. Background technique [0002] According to the "Construction Specifications for Underground Excavation of Hydraulic Structures", the scale of underground caverns is divided according to the excavation size and section size of underground caverns. According to the inclination angle, it can be divided into three types: flat tunnel, inclined shaft and vertical shaft. Among them, the inclination angle is 6 °-75° is an inclined well. In case of a steep slope, there are certain restrictions on the construction method and equipment selection, and the construction safety risk level is correspondingly increased. Therefore, it is difficult to choose a scientific and reasonable construction method to ensure the safety of construction operations, to organize construction quickly and effectively, and ...

AI Technical Summary

Problems solved by technology

Disadvantages: The cavern must be buried deep and shallow, which requires high concrete performance, and is prone to concrete segregation and pipe plugging

Disadvantages: The cavern must be expanded, occupying a large area, high investment costs, and prone to stress concentration, affecting the stability and safety of the cavern

Disadvantages: the transportation needs to be transported twice, the maintenance operation requirements are high, and the safety risk is large
