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

Abstract

The invention relates to a giant vertical shield machine, which is used for excavating foundation pits of large-scale engineering foundations, or foundation pits of underground buildings. It includes the following structure: an excavating mechanism, used for excavating a foundation pit; a protection mechanism, including a safety protection top cover covering the foundation pit, and the edge of the upper end surface of the safety protection top cover is suspended from the foundation pit by several steel wire ropes Middle; transport mechanism, including a first conveyor located above the safety protection top cover and a second conveyor located below the safety protection top cover, and a horizontally movable third conveyor is provided on the safety protection top cover A conveyor, the first conveyor is connected to the second conveyor through a third conveyor, and is used to transport the rock and soil to the first conveyor, and the first conveyor transports the rock and soil to the ground. A hydraulically driven concrete formwork is provided at the edge of the safety cover to complete the pouring of the 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...
