Problems solved by technology

[0002] At present, in the construction of urban tunnels and pipe networks in my country, the soil discharge methods of shield machines and pipe jacking machines are mainly screw machines and mud-water circulation. Among them, the screw machines and conveyor belts are commonly used for earth pressure balance, and the soil removal efficiency is low. , the transportation process is complicated
The mud-water treatment and separation system equipment commonly used in the mud-water balance shield machine is expensive, has a large environmental impact and occupies a lot of space, and the overall cost is abnormally high

Embodiment Construction

[0014] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as figure 1 A vacuum mud discharge shield system is shown, including the shield machine placed in the tunnel for propulsion, the completed pipe joints placed in the tunnel, and the mud generation and treatment system, vacuum pump and mud storage installed outside the tunnel tank; the head of the shield machine has a cutter head, and a cutter head cabin is set inside the cutter head; the outer side of the cutter head has a mud injection port; the mud generation and treatment system is connected to the cutter head through a mud delivery pipeline and will be installed in the mud generation and treatment system. The...

Abstract

The invention relates to a vacuum sludge discharge shield system. The vacuum sludge discharge shield system comprises a shield machine placed in a tunnel and used for propelling, pipe joints placed in the tunnel, a sludge generating and treating system, a vacuum pump and a sludge storage tank arranged outside the tunnel, and the like. High concentration sludge is utilized to fill in and pressurize an excavation surface and an overexcavation part; excavated muck and pebble are mixed to form condense sludge with collapsbillity approximately at 20; when the inner pressure and the outer pressure of a cutter head cabin reach critical balance, a lip vacuum mud valve is utilized to drain and discharge the sludge to a sludge storage tank in the machine. The workload efficiency is high; the safety is good; bad influences on the surface such as surface bulging, sinking and collapse cannot happen easily; the construction accuracy is excellently improved; the cost is reduced.

Description

technical field [0001] The invention relates to the field of tunneling equipment, in particular to a vacuum mud discharge shield system. Background technique [0002] At present, in the construction of urban tunnels and pipe networks in my country, the soil discharge methods of shield machines and pipe jacking machines are mainly screw machines and mud-water circulation. Among them, the screw machines and conveyor belts are commonly used for earth pressure balance, and the soil removal efficiency is low. , the transportation process is complicated. The mud water treatment and separation system equipment commonly used in the mud water balance shield machine is expensive, has a large environmental impact and occupies a lot of space, and the overall cost is abnormally high. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a vacuum mud discharge shield system with low cost, stable construction quality, high soil disch...
