Abstract
The reciprocating high-pressure spray-grouted foundation stabilization method belongs to the field of imperious treatment and foundation stabilization technology of rock-soil engineering, and is characterized by that in the interior of drill pipe a grout (water) air high-pressure spray pipeline and drilling water-jetting pipeline are mounted, and the grout, air and water transmission equipments and lift angle-tilting equipment are set, a walking carriage integrating drilling and grouting into one body is moved to drilling position, and the mechanical equipments are started, the liquid medium can be jetted to cut formation, and a mixed slurry is used for protecting hole wall, and when the required depth is reached, the cement grout is sprayed from bottom to top so as to form cement setting body or curtain.
Description
Technical field: the present invention relates to the antiseepage processing and the foundation consolidating technology field of geotechnical engineering, is reciprocating high-pressure jet grouting ground-strengthening method more specifically.
Background technology: the anti-consolidation process high pressure jet grouting commonly used that blends of present geotechnical engineering is the high spray of one-pass type, and cement consumption is many, creeps into high spray and carries out respectively, and equipment is complicated, and personnel selection is many, and work efficiency is low, the cost height, and the boring vertical precision is not high.
Summary of the invention:, the objective of the invention is to invent a kind of reciprocating high-pressure jet grouting ground-strengthening method for overcoming above-mentioned shortcoming.Its technical scheme is: become reciprocating type high spray by the high spray of one-pass type, jetting pipeline when slurry (water) gas high-pressure injection pipeline being installed in drilling rod and creeping into, be equipped with and carry slurry, gas, water and lifting pivot angle equipment, move to bore position with boring the walking chassis of irritating one, start plant equipment, carry liquid medium to creep into the injection cuts formation, make mixed serum hole slot is carried out retaining wall, when after require the degree of depth, make high jetting liquid into cement paste, (opening high-pressure air pipe when needing) closes discharge jet simultaneously, from bottom to top carries out the height spray, forms the cement solidifies body or curtain until the aperture design altitude.The advantage of this invention is: this method becomes reciprocating type high spray by the high spray of one-pass type, combines together creeping into high spray, has reduced equipment and operating personnel, adopt jet to creep into to have improved and creep into work efficiency and verticality, adopt reciprocating type high spraying speed degree fast, save cement, greatly reduce construction cost.
The specific embodiment: transform rig and high spraying equipment as bore the filling one walking chassis, jetting pipeline when slurry (water) gas high-pressure injection pipeline being installed in drilling rod and creeping into, be equipped with and carry slurry, gas, water and lifting pivot angle equipment, locate by the designing requirement unwrapping wire during work, chassis is moved to bore position, the gentle start plant equipment is installed, carry liquid medium, creep into injection cutting bottom by design parameters, make mixed serum, hole slot is carried out retaining wall, when after require the degree of depth, make high jetting liquid into cement paste, (opening high-pressure air pipe when needing) closes discharge jet simultaneously, from bottom to top carry out the height spray, form the cement solidifies body or curtain until the aperture design altitude.
