A New Slurry Shield Tunneling Integrated Machine

Abstract

The new mud-water type shield tunneling integrated machine of the present invention includes a cutter head drive system, a shield shell, a hydraulic propulsion system, a segment assembly mechanism, a U-shaped steel frame, a bottom segment, a segment transport trolley, a segment transport cart, Segment hoisting mechanism, mud water circulation system and mud ground processing mechanism, cutter head drive system is connected with hydraulic propulsion system, hydraulic propulsion system is connected with segment assembly mechanism, hydraulic propulsion system and segment assembly mechanism are set in the shield shell; The segment assembling mechanism is connected with the U-shaped steel frame, one end of the mud water circulation system is connected with the cutter head drive system, and the other end is connected with the mud processing mechanism on the ground; the segment assembling mechanism and the U-shaped steel frame are arranged on multiple segments Connected to form a circular cavity. Tunnel boring machine is a large-scale high-tech construction equipment specially used for excavating underground passages. It has the advantages of fast excavation, high quality, safety, economy, environmental protection and reduced labor intensity.

Description

technical field [0001] The invention relates to a tunnel boring machine, and more specifically, to a new mud-water type shield tunneling integrated machine. Background technique [0002] In modern urban construction projects, underwater highway tunnels, subway tunnels, municipal pipeline tunnels, highway tunnels, hydropower station construction, coal mining and other tasks are opened. The 21st century is the century of developing and utilizing underground space. The per capita urban rail length of major developed cities in the world is 0.39 km / 10,000 people, the per capita urban rail length of major cities in my country is 0.12 km / 10,000 people, of which the per capita urban rail length of Beijing, Shanghai, Guangzhou and Shenzhen is 0.22 km / 10,000 people, which is still far behind the average level. In general, there is a huge room for growth in the construction of urban rail transit in China. Various underground construction projects in China will be inseparable from tunnel...

Problems solved by technology

[0003] At present, the manufacturing process of shield machines on the market is complex, time-consuming, and has high technical added value. It is still in its infancy in China and mainly relies on imports. In domestic tunnel construction, Germany and Japan occupy a large market share in China's tunnel boring machine market The rate is as high as 95%, and it is in an absolute monopoly position
