Abstract
The invention relates to a construction machine of a high-pressure rotary-spraying anchor rod and a construction method of the high-pressure rotary-spraying anchor rod and belongs to the field of geotechnical engineering. Rich confined water is contained in sand and gravel layers, the holing is difficulty implemented by the anchor rod, water-flushing reverse circulation by a casing method can cause accidents such as piping, sand inrush, water inrush and land subsidence, and the sludge has no anchoring force, so that the anchor rod cannot be constructed at loose sand layers and sludge layers of fluvial facies and seashore facies, and only can an internal support method with high cost, long construction period and pollution to cities be adopted. The invention provides a novel drilling machine of the high-pressure rotary-spraying anchor. The drilling machine can be used for constructing rotary-spraying anchor piles, anti-floating anchor rods and tensile anchor rods along all directions such as the vertical direction, the horizontal direction and the inclined direction, and not only can be used for constructing large-diameter rotary-spraying cement-soil anchor piles, but also can be used for constructing anchor rods with expanded heads. The invention aims at providing the novel drilling machine of the high-pressure rotary-spraying anchor rod and the construction method of the high-pressure rotary-spraying anchor rod;, the difficulty that construction cannot be carried out due to no anchoring force in the sludge layer of mollisol is solved, and the conditions that a casing following method is adopted for constructing anchor bars into holes at the loose sand-gravel soil layer and the water-flushing reverse circulation can cause accidents such as piping, sand inrush, water inrush and land subsidence are avoided.
Description
Technical field
Patent of the present invention relates to a kind of high-pressure rotary-spray anchor bolt construction machinery in a kind of geotechnical engineering field and the job practices of high-pressure rotary-spray anchor pole thereof.
Background technology
Loose sand, mud in river facies and beach phase, the anchor pole of can not constructing, because: sandy gravel stratum contains abundant artesian water, anchor pole pore-forming difficulty, tiretube process water can produce piping towards returning circulation, gush accidents such as sand, water burst, land subsidence, mud does not have anchored force, can only adopt the cost height, long in time limit, the city had a method of polluting inner support.
Summary of the invention
Content of the present invention is to provide a kind of new high-pressure rotary-spray jumbolter, this high-pressure rotary-spray jumbolter can be vertically, level is to, oblique comprehensive construction churning anchoring pile and anti-floating, tension anchor pole, and this high-pressure rotary-spray jumbolter not only can perform the big direct rotary water spray earth anchoring pile enlarged footing anchor pole of constructing again.
Goal of the invention
Above-mentioned purpose of the present invention is to provide a kind of new high-pressure rotary-spray jumbolter, the job practices of high-pressure rotary-spray anchor pole, the difficult problem that solution can not be constructed in the mud of weak soil, no anchored force, must exempt from, at loose gravel soil layer, for porose dowel down adopts the sleeve pipe follow-up step, water produces the prominent accidents such as sand, water burst, land subsidence of gushing, gush towards returning circulation.
