Below the utility model made further specify.
Referring to Fig. 1, the water guide cell structure of two fluid grouting light rig of the present utility model comprises cylinder blanket 7 and is contained in this cylinder blanket 7 and upper/lower terminal is positioned at main shaft 13 outside the cylinder blanket, its design feature is, described cylinder blanket 7 middle parts are provided with hydroecium 8 and this hydroecium 8 and are communicated with the high-voltage quick joint 9 of cylinder blanket 7 one sides; The hypomere of described main shaft 13 is the hollow shaft that is provided with water transport channel 11, and the top of this hollow shaft is provided with the radially pod apertures 10 of a plurality of connection hydroeciums 8 and water transport channel 11; The upper/lower terminal of described cylinder blanket 7 is equipped with respectively with screw 2 and is fixed on pressure-bearing end cap 1 on this cylinder blanket 7, and between described pressure-bearing end cap 1 and the main shaft 13 O RunddichtringO 3 is housed; To hydroecium 8 plane bearing 4, needle bearing 5, V-type high-pressure seal ring 6 are housed successively between the main shaft 13 of each pressure-bearing end cap 1 inboard and the cylinder blanket 7 and by pressure-bearing end cap 1.
During actual installation, the upper end of described main shaft connects with the two fluid grouting light rig with corresponding connector, and the lower end of main shaft connects with the upper end of corresponding connector with hollow drill.
During real work, high-pressure injection pump pumping water under high pressure enters 8 hydroeciums by high-voltage quick joint 9; Hydroecium 8 under high pressure conditions, promptly under water under high pressure (7-21MPa) situation, cylinder blanket 7 pressurizeds, hydroecium 8 internal pressures pass to V-shaped seal ring 6, these V-shaped seal ring 6 pressurizeds are passed to needle bearing 5 again; Needle bearing 5 is combined closely with main shaft 13, by the needle bearing running, main shaft 13 is gone slick.Needle bearing 5 outsides are provided with plane bearing 4, this plane bearing 4 further seals with the hydroecium that pressure-bearing end cap 1 and O RunddichtringO 3 are combined to form under the axial compression state, and keep main shaft 13 to rotate flexibly relative to cylinder blanket 7 when pressure-bearing end cap 1 pressurized, it is connection main shaft 13 with the location of pressure-bearing end cap 1 that plane bearing 4 mainly acts on, separate rotation.High-voltage quick joint 9 can be connected with the water source easily, the position of corresponding hydroecium 8 is provided with radially pod apertures 10 on the main shaft 13, it is connected with the center water transport channel 11 of hydroecium 8 and main shaft 13 respectively, when the two fluid grouting light rig rotates, water is sustainable supply ceaselessly, make the water ejection by hollow drill again, reach the purpose that wet type is crept into;
Show that through field trial it is flexible, reliable that the utility model uses, and do not need any complicated operations program.General perforating workman just can operate, and water system can adapt under the high and low hydraulic pressure situation to be used, and drainage do not occur running.When using this system works, the work plane air is fresh, and dust produces 135mg/m by original dry type perforating
3, be reduced to 5-8mg/m
3, reach provisions of the relevant regulations issued by the State standard.It is 2-20 hydraulic pressure that this side formula water supplying apparatus adapts to hydraulic pressure, and using stabilization time is 18 months.This device can realize that under the high pressure conditions, the rig smooth operation is crept into, and the maximum pressure that can bear reaches 21Mpa.
In the structure of the present utility model, go slick behind the described plane bearing pressurized; Rig when boring band clear water, directly slip casting behind the pore-forming is particularly suitable for can be used for existing building ground stabilization on the complicated soft stratums such as drifting sand layer, fill stratum, pattern foundation pit supporting structure drilling construction at soft stratum, delamination pour slurry when drifting sand layer creeps into.This is because after powder spun yarn layer creeps into whole hole, under when managing slip casting, sand can return to Grouting Pipe, cause the plugging of powder spun yarn, after adopting this water guide cell structure, can realize creeping into and not stop boring and slip casting is changed fast, improve drilling efficiency, and can realize that marginal not slurry limit puies forward kinds of processes such as pipe, layer and section slip casting; Be fit to various bad grounds, be particluarly suitable for slip casting in the excessive stratum of artesian head.This device efficiently solves drifting sand layer, the dynamic problem of difficult slip casting behind the difficult pore-forming of current, the pore-forming.By rig bit change more, it can also be applied in the boulder bed to advance in the construction with pipe bit.
As known from the above, the utility model is a kind of water guide cell structure of two fluid grouting light rig, it is high pressure resistant, can under high and low pressure hydraulic pressure environment, use and percolating water phenomenon can not occur, and go slick, applied range, power consumption is few, the drilling efficiency height, speed of fulfiling hole is fast, cost is low, can inject multiple slurry material, slip casting effect is good, and is in light weight, simple in structure, easy to use, can solve various bad grounds, drifting sand layer, the dynamic problem of difficult slip casting behind the difficult pore-forming of current, the pore-forming, be applicable to various weak bad grounds.
