Abstract

The invention belongs to the field of mechanized equipment and underground structure engineering, and particularly relates to a multifunctional numerical control shaft sinking device. The multifunctional numerical control shaft sinking device comprises a floating workbench, a heading unit, a shaft and a shaft overlapped well with the same shape as the shaft. The floating workbench is provided with a mud pit, a mud water separating device, a pond and a high-pressure pump station. The heading unit is controlled by an operation control system and is placed in the shaft for underwater tunneling. The heading unit is connected with a soil discharging pipe and a high-pressure water supply hose. The shaft overlapped well is provided with three or more sinking propulsion units capable of collecting data, guiding, locating and correction. The shaft overlapped well is arranged at the connecting position of the shaft and the ground. Thixotropic slurry is injected into the gap between the shaft overlapped well and the wall of the shaft to serve as a lubricating device. By the adoption of the multifunctional numerical control shaft sinking device, the sinking perpendicularity and balance degree of the shaft are guaranteed through numerical control so that the shaft can achieve steady propulsion and safety sinking. The invention further discloses a construction method of the multifunctional numerical control shaft sinking device.

Description

technical field [0001] The invention relates to a multi-functional numerically controlled shaft excavation device and a construction method, which belong to the field of mechanical equipment and underground construction engineering, and are suitable for sewage treatment facilities, urban drainage projects, construction of underground pipe corridors, construction of working wells of shield machines, shaft-type underground three-dimensional Shaft excavation construction in garage. Background technique [0002] Shaft excavation is the construction process of digging a shaft (also known as a vertical shaft) vertically downward from the ground. There are two types of shaft excavation methods: ordinary construction method and special construction method. The common construction method is suitable for shaft excavation with small water inflow and relatively stable rock formation. The special construction method is suitable for shaft excavation in unstable rock formations (includin...
