Giant vertical shield machine

Abstract

The invention relates to a giant vertical shield machine which is used for excavating a foundation pit of a large engineering foundation or a foundation pit of underground buildings, wherein the diameter length of the foundation pit is 20-200 M, and the depth of the foundation pit ranges from 10 meters to hundreds of meters. The giant vertical shield machine comprises an excavation mechanism, a protection mechanism and a transportation mechanism; the excavation mechanism is used for excavating the foundation pit; the protection mechanism comprises a safe protection top cover covering the foundation pit, and the edge of the upper end face of the safe protection top cover is hung in the foundation pit through multiple steel wire ropes; the transportation mechanism comprises a first conveying machine located over the safe protection top cover and a second conveying machine located under the safe protection top cover, the safe protection top cover is provided with a third conveying machine which can horizontally moves, the first conveying machine and the second conveying machine are connected through the third conveying machine to convey rock and soil to the first conveying machine, and the first conveying machine conveys the rock and soil to the ground. The edge of the safe protection top cover is provided with a hydraulically-driven concrete formwork which is used for completing the pouring work of a concrete layer.

Description

technical field [0001] The invention relates to construction equipment for foundation pits in underground engineering, in particular to a giant vertical shield machine used for constructing underground foundation pits with a diameter of 20-200M. Background technique [0002] Today's world's ground buildings have developed to high-rise sky, and skyscrapers hundreds of meters high can be built. However, the underground construction has been lingering at a depth of several meters to more than ten meters, especially large-scale underground construction projects, which are greatly restricted because there are no efficient and safe special equipment. As a result, many projects that should be built underground can only be built on the ground, which not only cannot make full use of the underground space, but also is very unsafe, and fires are easy to occur. For example: national large-scale strategic oil depots, large chemical warehouses, large grain depots, oil depots at ports and...

Problems solved by technology

However, the underground construction has been lingering at a depth of a few meters to more than ten meters, especially for large-scale underground construction projects, because there is no efficient and safe special equipment, which is greatly restricted

As a result, many projects that should have been built underground can only be built on the ground. Not only can the underground space not be fully utilized, but it is also very unsafe and prone to fire

For example: national large-scale strategic oil depots, large chemical warehouses, large grain depots, oil depots at ports and airports, underground nuclear power plants, etc., are all greatly restricted due to lack of construction equipment
