Abstract
The utility model discloses an improved device for simultaneously injecting foam and bentonite into muck for an earth pressure balance shield machine. The improved device comprises a steel plate and a steel tube, the steel tube is arranged in the steel plate, and the width of one side of the upper portion of the steel plate is 60mm. The improved device has the advantages that 1, the purpose of simultaneously injecting a plurality of types of modifying agents is realized in a limited equipment space, namely the number of pipelines cannot be increased; and 2, pipeline jetting is controlled in a newly arranged control connecting valve system, a simultaneous injection purpose is realized by means of changing the flowing direction of pipelines, the improved device is low in workload, short in consumed time and easy in operation, and cost is correspondingly reduced.
Description
Technical field
The utility model relates to a kind of improved device, relates in particular to a kind of balancing earth-pressure shielding machine foam and swell soil and injects the dregs improved device simultaneously.
Background technology
The mode of the single filling soil conditioner of tradition, shield machine driving in easy incrusted stratum such as mud stone generally all needed 2-3 hour could tunnel a ring, and serious directly just can not tunnel; When in the layer of sand stratum of rich water, tunneling,, gush and to be effectively controlled, seriously restrict fltting speed because improvement is single; And have following defective: 1, cutterhead is prone to mud lining; 2, screw machine is prone to gush; 3, single soil conditioner can not reach the geological problem that solves whole piece tunnel complicacy.
The utility model content
The utility model technical problem to be solved is: the defective to prior art provides a kind of balancing earth-pressure shielding machine foam and swell soil to inject the dregs improved device simultaneously.
For solving the problems of the technologies described above, the technical scheme of the utility model is: balancing earth-pressure shielding machine foam and swell soil inject the dregs improved device simultaneously, comprise steel plate, and steel pipe is characterized in that steel pipe is arranged on steel plate inside.
The width of said steel plate top one side is 60mm.
The width of said steel plate top opposite side is 40mm.
The length of said steel pipe is 500mm.
The beneficial features of the utility model is: 1, in the limited device space, promptly can not increase under the situation of pipeline and realize the concurrently injected purpose of multiple modifying agent; 2, the utility model is reserved spout in native cabin, and through the reconfiguration pipeline, workload is little, and weak point consuming time is easy to operate, and cost is corresponding also low; 3, simultaneously injection device make can be according to the different soil property in the stratum that changes targetedly, effectively be injected in cutterhead the place ahead and the native storehouse simultaneously at water-rich sand layer through the foam line system; And carry out the adjustment of ratio; Carry out reclamation; Thereby overcome the knot cake, gush, a difficult problem such as native storehouse virtual pressure, remedied the defective of earth pressure balanced shield, EPBS worker method, particularly on the water-rich sand layer stratum; The layer of sand high water-permeability is easy to generate and gushs on the one hand, and layer of sand has effective the flowing of the difficult formation of big angle of friction on the one hand.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the steel work sketch map of the utility model.
Fig. 2 is the schematic diagram of the utility model injection device.
Among the figure, 1, steel plate, 2, steel pipe.
The specific embodiment
As shown in the figure, balancing earth-pressure shielding machine foam and swell soil inject the dregs improved device simultaneously, comprise steel plate 1, and steel pipe 2, steel pipe 2 are arranged on steel plate 1 inside.The width of said steel plate 1 top one side is 60mm.The width of said steel plate 1 top opposite side is 40mm.The length of said steel pipe 2 is 500mm; Be equipped with filling line simultaneously through the reservation steel pipe among Fig. 12, wherein the P4 road feeds cutterhead to this pipe-line system, the P4 road feeds native cabin, when water-rich sand layer tunnels; Make foam inject 4 spouts of cutterhead, 2 spouts in native cabin through controling the connection valve system; And swell soil solution is injected 2 spouts in native cabin, if when generally the stratum is tunneled, connect valve through controling; 8 spouts inject foam or inject swell soil solution, with operating system was consistent in the past.
