Description
Technical field
The utility model is related to underground pipe-driving technical field of construction, and in particular to one kind returning slurry for improving pipe jacking shield machine
The shield cutter device of efficiency.
Background technology
With quickly propelling for Chinese society expanding economy and Development of China's Urbanization, the development and utilization of urban underground space
It is operated in China to be in full swing, municipal administration synthesis pipe gallery also achieves considerable as the important component that urban underground space utilizes
Development.Pipe gallery is also referred to as " underground pipe gallery ", is the synthesis corridor of City Buried Pipeline, specifically in Urban Underground construction
One is integrated in one all kinds of municipal pipelines such as water, electricity, gas, heat, communication, and is equipped with special access hole, hoisting port and monitoring
System, people and small-sized machine can enter the tunnel space of operation in corridor.Pipe gallery is built in construction due to being constructed
The limitation of the urban environments factor such as place, road traffic so that traditional construction method is difficult to generally be applicable in.In such case
Under, the tunneling shield construction method that very little is influenced on the normal function in city is paid close attention to.Shield method tunnel construction specific purpose tool
For shield excavation machine, it is a kind of special engineering machinery of tunnel piercing, integrates mechanical, electrical, liquid, sensing, information technology, tool
There are the excavation cutting soil body, conveying dregs, assembled tunnel-liner, measurement to be oriented to the functions such as correction, is current state-of-the-art tunnel digging
Into equipment.Compared with traditional tunnel piercing technology, shield construction have to surrounding environment influence it is small, mechanization degree is high,
The advantages that speed of application is fast, construction cost is low, safety and environmental protection, especially in complex geologic conditions, level of ground water is high and edpth of tunnel
When larger, shield-tunneling construction can only be relied on.
The shield that China uses in underground engineering at present is broadly divided into earth pressure balanced shield, EPBS and slurry balance shield.Wherein
When slurry balance shield soil body in front of the shield cutting promotes by be adjusted the mud of pressure stablize in front of the soil body, and because of muddy water
Balance shield is completely in sealing state in entire tunneling process, is better than EPB shield tunneling to the stability on stratum, so mud
Water balance shield relies on its better stability and more reliable safety, also more comes about welcome.Slurry balance shield passes through
The soil body in front of knife cutting enters mud after the soil body is mixed with excavation storehouse mud after cutting by the mud door for being arranged in shield bottom
Slurry discharge line ground Slurry treatment field is delivered to by sludge discharge pipe road again, by Slurry treatment field to be delivered to ground muddy water into
Row separating treatment.
Slurry balance shield construction injects muddy water in the sealing compartment in shield tunneling face as shown in Figure 1, referring to, passes through mud
Water pressurizes and external pressure balance, to ensure the stabilization of the excavation face soil body.Before the soil excavated when shield driving enters shield
The muddy water room in portion, agitated device are stirred, and the high concentration muddy water after stirring is pumped into ground with muddy water, and muddy water passes through on ground
Separation is crossed, subsequently into the muddy water room of Tunnel Boring, constantly deslagging purification uses.Due to slurry balance shield slag tap completely according to
Rely circulating in mud, thus mud cycle it is unobstructed whether directly determine the efficiency of slurry balance shield construction.
