Background technology
It is high-pressure spray that conventional shower nozzle only has a kind of medium conventionally, can carry out cutting and crushing one time to the soil body, and all the other media are mesolow power, and slurries are that low pressure is filled in the soil body, and expanded diameter is little, depth as shallow.In the time that needing, the construction that runs into major diameter, super degree of depth stake can not meet the requirement of basis to pile.
And require to have higher sealing for high-pressure injection pipe, as only strengthened the pressure of medium in original structure, the part of shower nozzle inside cannot ensure that on compressive resistance and seal construction high-pressure medium does not leak outside and also do not gang up mutually.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of multimedium super-pressure shower nozzle is provided, and can meet the high-pressure spray needs of three kinds of working medias simultaneously.
The technical scheme providing according to the utility model, a kind of multimedium super-pressure shower nozzle, comprises bit body, the upper end of bit body is the link being connected with shotcrete pipe, the lower end jointed rod of bit body, the lower end of drilling rod connects cutter head; Feature is: in the inner chamber of described bit body, nozzle carrier is installed, the first spacer is set in the inner chamber of nozzle carrier, in the first spacer inner chamber, core pipe is set, the central through hole of core pipe is slurry passage, between the first spacer and nozzle carrier, form annular water-dilution channel, between nozzle carrier and the inwall of bit body, form annular air duct; The upper end of described core pipe is communicated with slush pump, and cutter head inside is stretched in the lower end of core pipe, and slurry nozzle is set on cutter head, slurry nozzle and slurry channel connection; On described bit body, water nozzle is set, the air nozzle of the arranged outside ring-type of water nozzle, water nozzle is communicated with water-dilution channel, and air nozzle is communicated with air duct.
Between the lower end of described core pipe and the inwall of cutter head, the second spacer is set, between the second spacer and core pipe and cutter head, seal is set respectively.
Between described core pipe and the first spacer, seal is set, in the lower end of water-dilution channel, seal is set, in the lower end of air duct, seal is set.
The number of described slurry nozzle is 1～2.
The number of described water nozzle is 1～2.
The utility model is compared with existing conventional shower nozzle, have the following advantages: (1) the utility model is by rational inner body and seal construction design, can meet three kinds of needs that working media is all high-pressure spray simultaneously, wherein, the pressure of clear water and cement paste can reach 40MPa, and compressed-air actuated pressure can reach 1.2 MPa; (2) the utility model can adapt to different construction technologies, as the spray technology of two kinds of media of needs, only of an inside part exchanging need to be become to physical member, and the obstructed medium of this runner can be reached; As only need a kind of medium spray technology, only two of an inside part exchanging need to be become to physical member, only retain through-flow can the reaching of runner of a medium; (3) cutter head that studs with carbide alloy is equipped with in shower nozzle described in the utility model lower end, can first be bored into voluntarily the end whitewash at soft formation, has improved efficiency of construction.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1～Fig. 2: multimedium super-pressure shower nozzle comprises bit body 1, nozzle carrier 2, air nozzle 3, water nozzle 4, the first spacer 5-1, the second spacer 5-2, core pipe 6, slurry nozzle 7, cutter head 8, air duct 9, water-dilution channel 10, slurry passage 11, drilling rod 12 etc.
As shown in Figure 1 and Figure 2, the utility model comprises bit body 1, and the upper end of bit body 1 is the link being connected with shotcrete pipe, the lower end jointed rod 12 of bit body 1, and the lower end of drilling rod 12 connects cutter head 8; Nozzle carrier 2 is installed in the inner chamber of described bit body 1, the first spacer 5-1 is set in the inner chamber of nozzle carrier 2, in the first spacer 5-1 inner chamber, core pipe 6 is set, the central through hole of core pipe 6 is slurry passage 11, between the first spacer 5-1 and nozzle carrier 2, form annular water-dilution channel 10, between nozzle carrier 2 and the inwall of bit body 1, form annular air duct 9; The upper end of described core pipe 6 is communicated with slush pump, cutter head 8 inside are stretched in the lower end of core pipe 6,1～2 slurry nozzle 7 is set on cutter head 8, slurry nozzle 7 is communicated with slurry passage 11, between the lower end of core pipe 6 and the inwall of cutter head 8, the second spacer 5-2 is set, between the second spacer 5-2 and core pipe 6 and cutter head 8, seal is set respectively; 1～2 water nozzle 4 is set on described bit body 1, the air nozzle 3 of the arranged outside ring-type of water nozzle 4, water nozzle 4 is communicated with water-dilution channel 10, and air nozzle 3 is communicated with air duct 9;
