Description
Technical field
The utility model relates to a kind of stirring boring mud device, relates in particular to a kind of pneumatic stirring boring mud device.
Background technology
In civil construction project, the vibro replacement stone column engineering in Hydraulic and Hydro-Power Engineering particularly, the Main Function of vibro replacement stone column is bearing capacity (mechanical property) or the anti-liquefying power that soft stratum or liquescent sand stratum is encrypted to improve ground.But need the stratum of vibroflotation compaction itself or superstratum to exist more closely knit (hard) stratum or existence to float the stratum such as cobble, boulder, cause vibrating impacter directly pore-creating penetrate firm hard formation, encrypt pile and adopt the mode in Churn drill power traction hole to penetrate to adopt again behind the firm hard formation vibrating impacter pore-creating to carry out the filler vibration to the projected depth.
The bore process in Churn drill power traction hole generally all adopts mud off, adopt direct circulation or instead circulate or take out mode that sand bucket takes out sand with outside the boring mud tap in the hole, will constantly guarantee the supply of qualified mud for guaranteeing the boring hole of not collapsing.Slurry coat method generally adopts local tonerde or swell soil to mix system.If there is not satisfactory qualified clay near the engineering location, need the qualified clay of long distance transportation or swell soil, cause using clay or bentonitic cost very high; The cost increase is especially obvious in the bad or remote situation of the on-site transportation condition of engineering.
If adopt direct circulation or the anti-mode of slagging tap that circulates, to arrange at the construction field (site) a lot of circulation mud sumps, along with the variation of work plane will be removed mud sump and backfill at any time, and then arrange new mud sump; If adopt the mode that sand bucket is slagged tap of taking out, to arrange at the construction field (site) many plasma discharge ditches or mud sump, and to arrange the personnel of some and the mud boring mud of the interior eliminating of plant equipment cleaning hole, above these several slagging-off modes all make the management of job site increase certain difficulty, increase corresponding Construction Cost.
The utility model content
The purpose of this utility model provides a kind of pneumatic stirring boring mud device that draws hole construction method be used to the punching of shaking with regard to being in order to address the above problem.
In order to achieve the above object, the utility model has adopted following technical scheme:
Pneumatic stirring boring mud device described in the utility model comprises percussive drill, hollow boring bit, airduct and air compressor machine, the top of described hollow boring bit is connected with the wire rope of described percussive drill and hangs on the described percussive drill, one end of described airduct be arranged in the pipe of described hollow boring bit or the pipe outer wall on, the other end of described airduct is connected with the air outlet of described air compressor machine.Wire rope at percussive drill is installed hollow boring bit, and provides pressure-air with air compressor machine, is transported in the pipe of hollow boring bit by airduct or pipe outer wall position, boring mud is suspended in the mud rolls in the hole, do not precipitate.
Particularly, when described airduct was arranged at the pipe outer wall of described hollow boring bit, described airduct was many, was symmetrically fixed on the outer wall of described hollow boring bit; Described airduct is preferably two.
As preferably, described airduct comprises iron pipe and flexible pipe, and corresponding with described hollow boring bit one section is described iron pipe in the described airduct, and described iron pipe is connected by described flexible pipe with the air outlet of described air compressor machine.
As preferably, described hollow boring bit is the staged hollow boring bit.
The beneficial effects of the utility model are:
1, employing pneumatic stirring boring mud device described in the utility model shakes to rush and draws the hole construction, because by wind-force boring mud being suspended in the mud rolls in the hole, does not precipitate, mud is forming the mud skin in hole wall exosmosis process, simultaneously in the hole mud because of deslagging not so that its density ratio is larger, played the retaining wall effect, the hole of can not collapsing of therefore holing;
2, because boring mud forms slurry coat method after mixing with mud jointly under the wind-force effect, so can not arrange or few waste discharge mud boring mud, reduced the expense of the artificial and plant equipment use of cleaning waste mud boring mud, reduce simultaneously the impact of environmental pollution, and improved the technical level of civilized construction;
3, because without stirred slurry, therefore saved the mud stirring of mud system and storage etc. and faced and build expenditure of construction and the cost of use of mud stirring equipment and the labour cost of mud stirring etc. of executing;
4, can use no or little qualified clay or use less underproof clay, therefore reduced significantly and need mix mud processed and use qualified clay or bentonitic expense, compare conventional method, can save and use clay or bentonitic quantity approximately 80～90%, save boring cost approximately 15～25%, bad, remote for transportation condition, local do not have again the object of construction production saving cost effectiveness of qualified clay more remarkable.
Description of drawings
Structural representation when Fig. 1 is pneumatic stirring boring mud application of installation described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described in detail:
As shown in Figure 1, pneumatic stirring boring mud device described in the utility model comprises percussive drill (not shown), staged hollow boring bit 4, airduct 2 and air compressor machine 1, the top of staged hollow boring bit 4 is connected with the wire rope of described percussive drill 6 and hangs on the described percussive drill, airduct 2 comprises iron pipe 7 and flexible pipe 8, one section that is arranged in the airduct 2 in the pipe of staged hollow boring bit 4 is iron pipe 7, and iron pipe 7 is connected by flexible pipe 8 with the air outlet of air compressor machine 1.Iron pipe 7 also can be arranged on the pipe outer wall of staged hollow boring bit 4, and then airduct 2 is two, and the iron pipe 7 in two airducts 2 is symmetrically fixed on the outer wall of staged hollow boring bit 4, and this structure does not illustrate in the drawings.
In conjunction with Fig. 1, adopt the utility model punching of shaking to draw the hole construction and may further comprise the steps:
