Description
One, technical field
The utility model relates to a kind of probing churning retaining wall drilling tool, is suitable for the application of bad ground deep drilling.
Two, background technology
China introduces high pressure jet grouting piling technique from late 1970s, through application study and the practice of more than 30 years, in technical know-how, construction technology and equipment, construction regulations and management, the aspects such as construction quality inspection have had significant progress and raising.
In troublesome zone drilling, prevention hole wall unstability is substantially identical with the technical measures of hole wall unstability process.The wall protecting method that bad ground is conventional has casing off, mud off, cement paste consolidation retaining wall etc., most bad ground mud all can be adopted to safeguard borehole wall is stablized, ensure to creep into carry out smoothly; Bore meet loose, broken, easily the weak complicated layer generation hole wall such as aquation dispersion collapse oversize time, in hole situation permit and follow-up work can ensure that induration is firm use the consolidation retaining walls such as cement; Creep into caving ground complicated especially, mud cannot be used to safeguard, and hole wall stablizes the general setting of casing isolation of the hole section invalid with consolidation retaining wall.In deep drilling and the special complex stratigraphic drilling of part, run into wide variety of conventional wall protecting method be difficult to solve hole in complex situations, give normally to creep into and bring great difficulty, corresponding solution is inquired in an urgent demand, as: one is in troublesome zone drilling, cause hole wall seriously to cave in, once form larger oversize hole section in hole, mud off effect declines, generally need grout injection retaining wall, during grout pouring, slurries, at the bottom of ostium in drilling rod, are from bottom to top replaced mud in hole, are tied up borehole space.When cement grout flows through " pregnant " in hole, be subject to mud dilution, pollute cement paste cannot effectively be solidified, or oversize space can not be occupied completely effectively form hole wall; Two is in bad ground deep drilling, also in being everlasting, hole, deep section bore meet loose, broken, easily aquation disperse complicated interlayer (tomography) and solution cavities such as caving in, maybe can not cannot adopt casing off, its top is when existing again the severe leakage being difficult to shutoff, the general serious unstability of hole wall, creep into and cannot carry out, especially based on small-caliber deep hole bad ground retaining wall.
Research and develop a kind of high-pressure rotary-spray cement paste consolidation breast wall apparatus for this reason and just seem very necessary.
Three, summary of the invention
The purpose of this utility model is to provide a kind of probing churning retaining wall drilling tool, and it can solve deep " fault gouge " retaining wall difficult problem.
For achieving the above object, the utility model design is carried out in the following way:
Probing churning retaining wall drilling tool, it comprises the drilling system be made up of mixer, suction water pipe, high-pressure injection pump, kelly, rig, drilling rod, material storing box, it also comprises churning retaining wall drilling tool, described churning retaining wall drilling tool stage casing week is along being equipped with some nozzles be communicated with churning retaining wall drilling tool central through hole, sealing one alloy bit bottom churning retaining wall drilling tool; The top loading or unloading of churning retaining wall drilling tool is bottom drilling system drilling rod; The hole section inner high voltage rotary lifting whitewashing that churning drilling tool can pierce underground under the effect of the rotation kelly of rig and drilling rod forms retaining wall cement sleeve pipe.
The utility model because be provided with churning retaining wall drilling tool bottom drilling system drilling rod, cement paste drilling system can carried in the section of hole by stage casing nozzle plenum churning, so can effectively form retaining wall cement sleeve pipe or water spray washes away; Simultaneously due to sealing one alloy bit bottom churning retaining wall drilling tool, so also can in dive in the section of hole; In addition drilling system basic comprising is changed owing to not lying in, so compact overall structure, be easy to dismounting.
Four, accompanying drawing explanation
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is the one probing churning retaining wall drilling system operating diagram according to the utility model proposes.
Fig. 2 is that enlarged diagram cuts open in the retaining wall of churning shown in Fig. 1 drilling tool office.
Respectively expression is identified in accompanying drawing:
1. mixer 2. suction water pipe 3. high-pressure injection pump 4. kelly 5. rig 6. drilling rod 7. churning drilling tool 8. nozzle 9. alloy bit 10. hole section 11. material storing box
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Five, detailed description of the invention
As shown in Figure 1 and Figure 2, the probing churning retaining wall drilling tool that the utility model proposes, it comprises the drilling system be made up of mixer 1, suction water pipe 2, high-pressure injection pump 3, kelly 4, rig 5, drilling rod 6, material storing box 11, it also comprises churning retaining wall drilling tool 7, described churning retaining wall drilling tool 7 stage casing week is along being equipped with some nozzles 8 be communicated with churning retaining wall drilling tool 7 central through hole, sealing one alloy bit 9 bottom churning retaining wall drilling tool 7; The top loading or unloading of churning retaining wall drilling tool 7 is bottom drilling system drilling rod 6; The hole section 10 inner high voltage rotary lifting whitewashing that churning drilling tool 7 can pierce underground under the effect of the rotation kelly 4 of rig 5 and drilling rod 6 forms retaining wall cement sleeve pipe.
Described nozzle 8 diameter is 3 ~ 5mm, length is 10 ~ 13mm.
Described nozzle 8 is 2 ~ 4.
Described alloy bit 9 head end diameter is 65 ~ 75mm.
During work, churning retaining wall drilling tool assembling, under enter boring before, should spray be interviewed with carrying out, and check the integrity of high-pressure injection pump 3 and the reliability of equipment and pressure, kelly 4 rotary speed etc., the rear that meets design requirement is carried out successively in the following order: determine retaining wall hole section 10, assembling churning drilling tool 7 and under enter churning drilling tool 7, configuration slurry wall, mud jacking churning promote, churning drilling tool, cleaning churning facility are proposed, wait solidifying with sweep cement.If when retaining wall hole section 10 is darker, block for avoiding that nozzle 8 occurs in hand-hole process, after examination spray is normal, nozzle 8 sealed up by available adhesive tape.
