Description
Technical field
The present invention relates to shield machine technical field, particularly relate to a kind of foam jet and shield machine foaming system.
Background technology
The compliance of earth pressure balance shield machine to geology is poor, especially in the work progress to clay, silt and sandy silt soil stratum, because the angle of internal friction of this ground layer soil body is larger, glutinous poly-property is stronger, usually cause cutterhead to tie " mud cake " and conveying worm to be unearthed the generation of the phenomenons such as difficulty, bring huge difficulty to shield-tunneling construction, therefore shield machine all uses foaming system to improve the soil body to prevent the generation of above phenomenon in work progress; But because in foaming system, the pressure of each pipeline is uneven, the foam flow often causing each foam jet to export and pressure inequality, cause the blockage problem that foam jet exports, cause have a strong impact on to construction speed.
Summary of the invention
The technical problem to be solved in the present invention is, for the susceptible to plugging above-mentioned defect of foam jet outlet of shield machine foaming system in prior art, provides a kind of and effectively can avoid the blocked foam jet of outlet and shield machine foaming system.
The present invention, for solving the problems of the technologies described above, provides a kind of foam jet, and its technical scheme adopted is as follows:

In foam jet of the present invention, above-mentioned foam inlet pipe and foam pipeline are all mainly used in carrying foam in work progress, rear end and the driving mechanism of above-mentioned rabbling mechanism are in transmission connection, and this rabbling mechanism is placed in the internal cavities of this foam pipeline along the axis of foam pipeline, when foam pipeline foam outlet blocking or foam volume reduce to a certain degree time, rabbling mechanism can rotate under the driving effect of driving mechanism, the dregs of the foam outlet blocking of such foam pipeline can be discharged along with the motion of rabbling mechanism, it can thus be appreciated that, compared with prior art, foam jet provided by the invention effectively can prevent the foam flow because each foam jet exports and pressure uneven and cause the problem of outlet obstruction, thus contribute to improving efficiency of construction.
The axial forward end of above-mentioned foam pipeline is connected with cutter head rear panel with cutterhead front panel respectively with axial rearward end, and such design facilitates the installation of foam pipeline, also contributes to the installation strength of reinforced foam carrier pipe; In addition, above-mentioned driving mechanism is also connected with cutter head rear panel, and such design also facilitates the installation of driving mechanism, is more conducive to the installation strength strengthening this driving mechanism.
Preferably, above-mentioned driving mechanism is motor, and this motor is connected with the control mainboard separately established.This motor realizes automatic start-stop under the control controlling mainboard.
Further, in the internal cavities of above-mentioned foam pipeline, be provided with flow transmitter, and flow transmitter is connected with the communication of above-mentioned control mainboard.When the data on flows of the foam pipeline inside that flow transmitter detects reaches default lower limit, above-mentioned motor just can start under the control controlling mainboard, when the data on flows of the foam pipeline inside that this flow transmitter detects is higher than the lower limit preset, motor just automatically can shut down under the control controlling mainboard, and being namely provided with of flow transmitter helps described foam jet and realize automatically working.
Preferably, above-mentioned driving mechanism is hydraulic motor, and the inlet of this hydraulic motor and liquid outlet are respectively equipped with feed tube and drain pipe, and this feed tube and drain pipe are communicated with foam pipeline with above-mentioned foam inlet pipe respectively.When foam pipeline foam outlet blocking or foam volume reduce to a certain degree time, hydraulic motor can operate automatically, thus drive rabbling mechanism to rotate, the dregs of the foam outlet blocking of such foam pipeline can be discharged along with the motion of rabbling mechanism, meanwhile, foam solution cognition enters into foam pipeline by foam inlet pipe, feed tube, hydraulic motor and drain pipe successively, thus plays the effect adding foam; When the foam outlet of foam pipeline normally works, hydraulic motor can shut down automatically, and rabbling mechanism also can stop the rotation, and now, foam solution cognition directly enters into foam pipeline from foam inlet pipe.Therefore, the start and stop of hydraulic motor do not need manual operation, also do not need by programme-control, and rely on the foam outlet of foam pipeline whether to block the start and stop of automatic hydraulic control motor completely, it is extremely convenient to use.
Preferably, above-mentioned rabbling mechanism is stirring rod.
Preferably, above-mentioned rabbling mechanism surface is provided with spiral groove.When rabbling mechanism rotates, spiral groove can impel the dregs of the foam outlet being blocked in foam pipeline to discharge, and being namely provided with of this spiral groove helps discharge dregs easily and quickly, enhances casting function to a certain extent.
Present invention also offers a kind of shield machine foaming system, this shield machine foaming system comprises the foam jet of multiple said structure.
In addition, in technical scheme of the present invention, to be allly not specifically noted, all by adopting the routine techniques in this area to realize.
Therefore, foam jet provided by the invention and shield machine foaming system effectively can prevent the foam flow because each foam jet exports and pressure uneven and cause the problem of outlet obstruction, contribute to the efficiency of construction improving shield machine.
