Sinking rotary shaft boring machine

Abstract

The invention provides a sinking rotary shaft boring machine, and relates to the technical field of shaft boring machine engineering machinery. The machine comprises a boring mechanism, a power lifting mechanism arranged on the ground for lifting the boring mechanism, a slurry separation mechanism for discharging and processing used for lifting, discharging and treating mud slurry mud generated after the boring mechanism breaks earth in a shaft and an operation control system for controlling the operation of each of the above mechanisms, the boring mechanism includes a boring frame, a drill arm, a main drive device for driving the rotation of the drill arm, a drilling tool and auxiliary drive devices for driving the drilling tool to rotate, and the lower portion of the main drive device isconnected with the middle of the drill arm; at least two auxiliary drive devices are mounted on the drill arm, and the lower portions of each auxiliary drive device is connected with the drill tool;the machine has reasonable design and small space occupation, full-section excavation is achieved by the rotation of the drill arm and the drilling tool, the rotation speed and direction of the drillarm and the drilling tool can be adjusted, and the machine is suitable for different geological conditions.

Description

technical field [0001] The invention relates to the technical field of shaft boring machine engineering machinery, in particular to a rotary shaft boring machine with a sinking method. Background technique [0002] It is well known that with the development of the national economy, the construction of urban rail transit and the construction of urban underground pipe corridors have developed rapidly in recent years; in the construction of underground projects, such as shield starting and receiving shafts, mining shafts, tunnel ventilation shafts, underground fortification shafts, In the construction of underground parking lots, mine roadways, traffic tunnels and other underground projects, in order to ensure the smooth progress of the construction, it is necessary to excavate shafts for transporting materials and ventilation. The upper end of the shaft is connected to the ground, and the lower end of the shaft is connected to the roadway or tunnel. Shaft excavation is the co...

Problems solved by technology

In the current vertical underground space construction, most of the traditional artificial foundation pit support and excavation methods are used, that is, manual excavation at the bottom of the well, while excavating and making the well wall or sinking the well wall for support, this construction method The disadvantages are slow excavation speed, low degree of mechanization, long construction period, high construction cost, low safety of construction personnel, and high risk. Therefore, there is an urgent need for a sinking shaft construction equipment suitable for the development of urban underground space.
