Description
Technical field
The present invention relates to slurry shield field, refer to a kind of system switching muddy water loop control pattern especially, the driving of Different Strata can be adapted to.
Background technology
At present, along with a large amount of constructions in domestic and international tunnel, shield machine becomes first-selected, and slurry shield, with its excellent Stress control performance, crossing river, is crossed in sea and the construction of tunnel that has higher requirements to sedimentation and is widely used.
Current slurry shield mainly contains two kinds of forms, and one is direct control type, and another kind indirectly controls formula.Mud is delivered directly to muddy water storehouse by direct control type slurry shield, and dregs is also direct simultaneously discharges from muddy water storehouse, and its advantage is that deslagging is smooth and easy, should not deposit blocking, and shortcoming is that pressure controling precision is low, fluctuates larger; And indirectly control formula slurry shield and add an air cushion storehouse at rear portion, muddy water storehouse, mud both can be transported to air cushion storehouse also can be transported to muddy water storehouse, and dregs exports from bottom, air cushion storehouse, and the Water And Earth Pressures of balance face regulates automatically by air cushion storehouse gas, its advantage is that pressure controling precision is high, fluctuate little, shortcoming is that dregs is flow velocity step-down herein because air cushion Cang Chu exists one section of conveying blind area, easy formation deposition, not easily carry, especially meet the dregs that particle diameter is larger, cause deslagging not smooth.
In order to better adapt to Different Strata, the advantage merging two kinds of slurry shields is exactly a problem needing to solve.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, propose a kind of muddy water circulatory system that can directly and indirectly control and control method, can realize directly and indirect two kinds of control modes, be adapted to Different Strata driving.
Technical scheme of the present invention is achieved in that a kind of muddy water circulatory system that can directly and indirectly control, comprise into slurry house steward and plasma discharge house steward, enter to starch between house steward and plasma discharge house steward and be connected with bypass pipe, entering to starch house steward is provided with into stock pump, plasma discharge house steward is provided with slurry pump, enter to starch on house steward and be connected with the first inlet pipe and the second inlet pipe, plasma discharge house steward is connected with the first discharge pipe and the second discharge pipe, first inlet pipe, first discharge pipe is connected to muddy water storehouse, second inlet pipe, second discharge pipe is connected to air cushion storehouse, first inlet pipe, second inlet pipe, first discharge pipe and the second discharge pipe and bypass pipe are equipped with control valve.
A kind of muddy water circulatory system directly and method for indirectly controlling, carry out in the following manner: when not easily producing the stratum driving of massive deposit, adopt indirect control model, now enter stock pump and slurry pump unlatching, open the second inlet pipe and the second discharge pipe, open mud door, close or open the first inlet pipe, close the first discharge pipe; When easily producing massive deposit stratum driving, adopting direct-type control module, now entering stock pump and slurry pump unlatching, closing the second inlet pipe and the second discharge pipe, close mud door, open the first discharge pipe and the first inlet pipe; When indirect control model and direct control mode switch, open the control valve on bypass pipe.
This device can realize the muddy water circulatory system of slurry shield, can be implemented in the function directly controlling and indirectly carry out between control model to switch.Adopting indirect type control model when not easily producing massive deposit stratum driving, ground settlement can be controlled preferably; Then adopting direct-type control model when easily producing massive deposit stratum driving, the conveying blind area that air cushion storehouse produces can be avoided, prevent accumulated plugging.This apparatus structure is simple, easy and simple to handle, practical, is the important leverage of safety, efficient construction.
