Abstract
The utility model discloses a slurry shield's novel quarrying case, including the box, be equipped with the grid in the box, the box both ends are equipped with into thick liquid mouth and grout outlet respectively, grid upper portion is equipped with flush pipe, and the last evenly distributed of flush pipe has the nozzle. The utility model discloses with the grid with advance thick liquid mouthful, grout outlet parallel arrangement, changed the form of arranging of grid, that avoids the box advances a thick liquid mouthful direct impact grid, makes rectangular shape stone circulate along the grid, can't be through the hole of grid, the rectangular shape stone of the effectual collection of ability when slurry shield tunnels to the slurry pump has been reduced by the probability of jamming, simultaneously, on the road a plurality of of the inside flush pipe of box erode the nozzle can increase the box in the mobile of mud can erode the grid simultaneously, ensured the smooth and easy flow of mud in the box, reduced the jam of grid, improved the tunnelling efficiency that the shield constructs the machine.
Description
Technical field
This utility model relates to the technical field of slurry shield, is specifically related to the novel quarrying case of a kind of slurry shield, for filtering the ratchel and bar shaped stone gathered on slurry shield plasma discharge pipeline.
Background technology
At present, along with a large amount of constructions in domestic and international tunnel, shield machine becomes first-selected.Slurry shield, with its excellent Stress control performance, has obtained commonly used in river excessively, excessively sea and the Tunnel Engineering having higher requirements sedimentation.Slurry shield needs to be full of in mud hydraulic pressure indoor the muddy water of pressurization in construction, seeks stablizing of excavation face by pressurization and pressure holding.The native sand that shield machine cutting gets off, send with the fluid form of mixing muddy water, in the slurry pump porch of conveying mixing muddy water, one quarrying case is installed, to prevent the stone clamping stagnation having more than slurry pump delivery specifications in slurry pump, cause slurry pump to quit work, and affect the work efficiency of development machine.
When slurry shield tunnels in the stratum that rock ratio is high, traditional quarrying cell grid with enter/plasma discharge mouth is arranged vertically, but the collection effect that this arrangement is less than the longer bar shaped stone of grate opening length for cross-sectional area is general, most of bar shaped stones can enter in slurry pump by grid, thus result in the frequent clamping stagnation of slurry pump, have a strong impact on drivage efficiency and the working efficiency of shield machine.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides the novel quarrying case of a kind of slurry shield, washes away form by changing the arrangement form of grid with internal, decreases the fault rate of slurry pump, improve the work efficiency of shield machine driving.
In order to achieve the above object, the technical solution of the utility model is: the novel quarrying case of a kind of slurry shield, including casing, is provided with grid in casing, and described tank ends is respectively equipped with stock inlet and grout outlet；Described grid top is provided with flush pipe, and flush pipe is evenly distributed with nozzle.
As optimal way of the present utility model, described grid is arranged between stock inlet and grout outlet, and grid is paralleled with stock inlet, grout outlet.
As optimal way of the present utility model, described flush pipe is connected with the pump that washes away on main pulp-inlet pipe road by rinsing ball valve, rinses ball valve and is arranged on the outside of casing.
As optimal way of the present utility model, described flush pipe is arranged on the both sides of casing, and nozzle is close to grid.
Grid is be arranged in parallel by this utility model with stock inlet, grout outlet, change the arrangement form of grid, the stock inlet avoiding casing directly impacts grid, strip stone is made to circulate along grid, grate opening cannot be passed through, can effectively gather strip stone when slurry shield tunnels, thus decrease slurry pump by the probability of clamping stagnation；Meanwhile, some nozzles that wash away that box house washes away on pipeline can increase the mobility of mud in casing and can wash away grid simultaneously, ensured the smooth outflow of mud in casing, decreased the blocking of grid, improve the drivage efficiency of shield machine.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is right view of the present utility model.
Fig. 3 is plan structure schematic diagram of the present utility model.
Wherein, 1 is casing, and 2 is mud ball valve, and 3 is flush pipe, and 4 is grid, and 5 is nozzle, and 6 is plasma discharge mouth, and 7 is stock inlet.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not paying creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1, Figure 2 and Figure 3, the novel quarrying case of a kind of slurry shield, including casing 1, in casing 1, it is provided with grid 4, described casing 1 is respectively arranged at two ends with stock inlet 7 and grout outlet 6, and the height of stock inlet 7 is higher than the height of grout outlet 6.The cross section top of casing 1 be rectangle, bottom be that arc, casing 1 lower end are provided with the support for supporting box.Grid 4 is arranged between stock inlet 7 and grout outlet 6, and grid 4 is paralleled with stock inlet 7, grout outlet 6, and the mixing mud that this avoid stock inlet 7 inflow is perpendicular to the flowing of grid 4, and makes mixing mud be parallel to the direction flowing of grid 4.
Grid 4 top is provided with flush pipe 3, and flush pipe 3 is evenly distributed with nozzle 5, and each flush pipe 3 is provided with 2 to 5 nozzles 5.Flush pipe 3 is arranged on the both sides of casing 1, and nozzle 5 is close to grid 4, it is possible to wash away the whole surface of grid 4.During slurry shield machine tunnels, strip stone enters from stock inlet 7 along with mud, flow along grid 4, because stone length cannot be by being collected more than the aperture of grid 4, washing away pipeline 3 and frequently grid 4 can be washed away and ensure its through-flow property casing 1 within.
Preferably, flush pipe 3 is connected with the pump that washes away on main pulp-inlet pipe road by rinsing ball valve 2, rinses ball valve 2 and is arranged on the outside of casing 1.Flush pipe 3 and nozzle 5 utilize the fresh slurry washing away pump offer to wash away grid 4.
This utility model is by changing grid 4 arrangement form of tradition quarrying case, and grid 4 top adds flush pipe 3, gathers bar shaped stone by grid 4 in slurry shield tunneling process.Grid 4 is constantly washed away by flush pipe 3, not only ensure that bar shaped stone was collected by filtration but also makes dregs to discharge from plasma discharge mouth 6 smoothly, ensure that slurry pump normally works and the circulation of circulation pipeline is smooth and easy, effectively reduced the fault rate of slurry pump, improve the drivage efficiency of slurry shield machine.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
