Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like figure 1 As shown, the embodiment of the present invention provides a mud-water shield mud preparation process. The mud preparation work flow is mainly: new slurry tank→adjustment tank→shield machine→mud-water separation equipment→over-settling tank 1→over-settling tank 2→ Filter press sedimentation tank→filter press equipment→slag field / clean water tank.

[0020] The slurry discharged from the shield machine adopts a step-by-step self-flow method, and its main process is: mud-water separation equipment→over-sedimentation tank 1→over-sedimentation tank 2→adjustment tank / filter press sedimentation tank→P pump→shield machine.

[0021] Construction clean water is all pumped, and its main process is: clean water tank→new slurry tank / over-sedimentation tank 1, over-sedimentation tank 2→adjustment tank→shield machine→slurry-water separa...

Abstract

The invention discloses a slurry shield slurry modulation process, the main process is as follows: pumping the size prepared by a new pulp chest to a regulation pool through a pump; regulating through a regulation pool; conveying to a shield machine through a slurry convey pump; the size exhausted by the shield machine is dehydrated by vibration through a separation device of water and muddy in a mode of automatic flow step by step through a first transition settling pond, a second transition settling pond, a regulation pool or a filter-press settling pond; and then conveying to the shield machine through the pump. In the invention, the filterpress is cooperated with the slurry shield to treat the waste slurry; the project cost is lowered; the process has no influence on the environment; the invention is mainly used for regulating the muddy required by the slurry shield by using clean water and the slurry shield, and reduces the working procedure steps, time and required devices by more than 50%.

Description

technical field [0001] The invention relates to a mud preparation process, in particular to a mud-water shield mud preparation process, which belongs to the technical field of tunnel engineering. Background technique [0002] In the 1990s, the mud preparation process and its devices were successively used in fields such as sludge treatment, waste water recycling, hydropower, urban construction, and other positive and negative circulation holes (slots). The engineering conditions faced at this stage were simple, and the engineering site was relatively fixed. Both mud composition and consumption are less. [0003] With the rise of the subway industry in the 21st century, mud modulation technology has been widely used in subway shield construction. Due to the long mileage of the subway tunnel project, complex engineering conditions, and rapid and complex geological changes, the subway construction is generally located in the bustling areas of the city. The mud preparation proc...
