Climbing tank method for excavation in hoist operation

The hoisting method of the jacking method of the hoisting machine is also called the Alimak method. It is the construction method of the Shaft boring machine in Sweden. It is also the method adopted in the hoisting tunnel engineering in the world. Because of this method I inclination, a variety of lengths and the use of a variety of rock in the excavation is simply to say that climbing a tank is a transportation tool for manned goods.

In the process of lifting the hoistway from the bottom up, the two members will assemble and fix the special track one by one on the wall of the cave so that the hoistway track will be close to the work surface at any time. The climber climbs up and down the track and sends workers and work equipment to the work surface. At the same time, he provides the staff with a job to complete drilling, filling and digging operations. During blasting and dust removal, the climbing tank retreats from the working surface to cover the underside of the top arch of the hoisting hole, so that the climbing tank is well protected.

Because the track is a standard part, it can be replaced with a new one regardless of the track title, and the replacement of the track is also very convenient. Alikack patio climbing tanks are wind-driven, electric and diesel hydraulic drive three forms, according to cross-sectional area of ​​the patio, long construction conditions, choose to use the appropriate climbing cans. :

The emergence of bucket elevators for climbing can basically solve the difficult problems of ordinary tunneling methods. The advantages of hoisting cans include: 1 The bucket elevator is easy to lift from the bottom up; 2 The elevator climbs the tank up and down the track. The staff can quickly reach the work surface; 3 Climbing tanks can be fixed on the workers' bamboo track, and they can immediately provide workers with temporary working platforms for construction; 4 Pipelines in special track of grain elevators , poor expansion and contraction The air and water are sent to the rock drill and they also play the role of ventilation and dust removal after blasting.
