Abstract
A self-positioning type spring guiding plate ribbed cement soil anchor drill bit and a construction method thereof have the advantages of being capable of one-time achieving anchor cable hole-forming, steel strand installation and cement slurry injection to achieve anchor cable production when formations with large water content such as mucky soils and sand stone are encountered; enabling a plurality of steel strands to be brought in according to design requirements due to the fact that the plurality of steel strands can be one-time brought into the design depth without recycling through a self-positioning spring guiding plate which is arranged on a homemade drill bit; enabling the opening range of a self-leaf to be automatically adjusted according to an aperture size through a self-positioning spring which is arranged on a guiding plate to control the drilling direction to prevent the steel strands and a drill rod from being wound with each other; and shortening the construction time, improving the working efficiency and reducing the construction costs.
Description
Technical field
Patented technology of the present invention relates to building field, particularly geotechnical engineering side slope foundation ditch cable bolting and job practices.
Background technology
In the bolt support construction, when running into for the big stratum of water content such as mucky soil, sandstone, tradition anchor cable construction technology is difficult to solve the problem of making anchor cable and can't pore-forming causing steel strand and drilling rod winding, reduce efficiency of construction, increase construction cost, can't guarantee that the stretch-draw value reaches designing requirement, thereby can not guarantee the stability of bolt support.
Summary of the invention
Patent of the present invention technical problem to be solved is when running into the big stratum of water content such as mucky soil, sandstone, can once finish the anchor cable pore-forming by this invention, and following steel strand, cement injection are finished anchor cable and made; Also can bring the multi beam steel strand into by designing requirement, self-align spring deflector on the self-control drill bit can will not reclaim the disposable projected depth of bringing into of multi beam steel strand, the amplitude of opening that self-align spring on the deflector will be automatically regulated himself blade according to pore size, thereby control drilling direction, prevent that steel strand and drilling rod are intertwined mutually; Shorten the engineering time, increase work efficiency, reduce construction cost.
The concrete construction sequence of the present invention comprises:
(1), calibration position, anchor cable hole drilling construction
Jumbolter in place by high-voltage tube with stir slurry jar, high-pressure injection pump links together, calibration position, anchor cable hole will be laid by the self-localization-type spring deflector cement-soil earth anchor drill bit that designing requirement has steel strand and be put the drilling rod front end.By the drill power head rotary drill bit, open the high-pressure injection pump cement paste circulating system when sending it to stratum; The spring of the self-localization-type band muscle deflector in the drilling process on the drill bit will be regulated it automatically with its pore size and open amplitude, and the control drilling direction avoids being with muscle (steel strand) and himself drilling rod to stir tangle up.
(2), move back brill and finish anchor cable later stage technology
Back is extracted drilling rod and is carried out high pressure cement slip casting simultaneously after creeping at the bottom of the hole, drill bit will separate it by self-localization-type deflector back tension force with drilling rod when moving back brill, steel strand will be stayed projected depth simultaneously, the promotion speed that only must slow down during surplus 6 meters drilling rods in the anchor hole treats to extract fully when cement paste is overflowed in the aperture drilling rod.After finishing the grouted anchor bar moulding, carry out the anchor cable health, waist rail, pedestal and ground tackle are installed by designing requirement, by designing requirement stretch-draw and locking, finish construction at last.
This job practices is finished the drill bit directed drilling by the spring deflector on the self-control self-localization-type spring deflector cement-soil earth anchor drill bit, and brill is moved back in the location, and the permanent steel strand of inserting, and once finishes;
