Shield structure soil storehouse water under high pressure flushing system
Technical field
The present invention is a kind of technology preventing shield structure Tu Cang from producing mud cake, is specially a kind of shield structure soil storehouse water under high pressure flushing system being applied to earth pressure balanced shield, EPBS and slurry shield.
Background technology
Along with the not only development of society, especially constantly the carrying out of the underground construction construction such as tunnel, shield structure then becomes a kind of digging tool indispensable in constructing tunnel.
Shield cutter is in tunneling process, the mobility of soil storehouse dregs is often poor, particularly Tu Cang centre very easily forms mud cake, once generation mud cake, have a strong impact on drivage efficiency and the project construction progress of cutterhead, be embodied in the increase of shield structure gross thrust, cutter head torque increases, cutterhead pile penetration is low, driving speed is slow, native storehouse dregs temperature is high.
Therefore, how can improve the dregs mobility in native storehouse, prevent from producing mud cake in native storehouse, and then improve construction driving speed, reducing shield structure gross thrust, has been a good problem to study.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the present invention is directed to shield structure soil capacity and easily forming mud cake, providing a kind of mobility effectively being improved native storehouse dregs by water under high pressure flushing system, prevent Tu Cang from producing the shield structure soil storehouse water under high pressure flushing system of mud cake.
The object of the present invention is achieved like this:
Shield structure soil storehouse water under high pressure flushing system, it is characterized in that: comprise supporting after being arranged on shield structure in the centrifugal multistage pump multiple centrifugal pump 8 be connected with water system detergent line 7, centrifugal multistage pump multiple centrifugal pump 8 is connected with the main driving of shield structure or anterior shield dividing plate 2 by high-pressure water pipe 1, soil bulkhead 5 and centre 6 are provided with swash 3, in swash 3, are provided with high pressure water flushing brush device 4;
Described high pressure water flushing brush device 4 is arranged on swash 3 by bolt, is connected with high-pressure water pipe 1 simultaneously;
Described high-pressure water pipe 1 is provided with pneumatic ball valve 9, manual ball valve 10, flap valve 11 and flow meter;
Described flap valve 11 is screw thread Vertical Lift Check Valves;
Described high pressure water flushing brush device 4 can be sprayed water, foam or swell soil;
Described high pressure water flushing brush device pushes down the thick rubber pad of one deck 5mm by a pressure ring, and rubber pad has cut " ten " font seam, gap is 1mm, is provided with several apertures of logical water under high pressure bottom rubber pad.
beneficial effect:the present invention is by increasing water under high pressure flushing system, in cutterhead tunneling process, open water under high pressure according to formation variation and wash away or control the flow that native storehouse water under high pressure washes away, improve the mobility of native storehouse dregs timely and effectively, prevent Tu Cang from producing mud cake, the present invention is applied to earth pressure balanced shield, EPBS and slurry shield; High pressure water flushing brush device is back of the body dress bolt fixed mode, makes simple, easy to maintenance; Flushing device, except spray water under high pressure, can also lead to foam, swell soil etc.; Swash can a bite multiplex, high pressure water flushing brush device remove after, can process native storehouse boulder or beat anchor pole to before cutterhead by swash, without the need to artificial warehouse entry.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present invention;
Fig. 2 is a portion structure for amplifying schematic diagram in Fig. 1;
Fig. 3 is structural representation two of the present invention;
Fig. 4 is system principle control chart of the present invention;
In figure be: high-pressure water pipe 1, the main driving of shield structure or anterior shield dividing plate 2, swash 3, high pressure water flushing brush device 4, native bulkhead 5, centre 6, water system detergent line 7, centrifugal multistage pump multiple centrifugal pump 8, pneumatic ball valve 9, manual ball valve 10, flap valve 11.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further:
As shown in Figure 1, Figure 2, Figure 3 shows, shield structure soil storehouse water under high pressure flushing system, comprise supporting after being arranged on shield structure in the centrifugal multistage pump multiple centrifugal pump 8 be connected with water system detergent line 7, centrifugal multistage pump multiple centrifugal pump 8 is connected with the main driving of shield structure or anterior shield dividing plate 2 by high-pressure water pipe 1, soil bulkhead 5 and centre 6 are provided with swash 3, in swash 3, are provided with high pressure water flushing brush device 4;
Described high pressure water flushing brush device 4 is arranged on swash 3 by bolt, is connected with high-pressure water pipe 1 simultaneously; Described high pressure water flushing brush device pushes down the thick rubber pad of one deck 5mm by a pressure ring, rubber pad is natural rubber, rubber pad cuts " ten " font seam, gap is 1mm, several apertures of logical water under high pressure are provided with bottom rubber pad, under the pressure effect of water under high pressure, rubber opens, inject high pressure water; When water under high pressure is closed, rubber pad, because of flexible original state of automatically rebounding, can stop native storehouse silt to enter high-pressure water pipeline, i.e. the non-return valve function of high pressure water flushing brush device.
