The utility model mainly by pore-forming hole flushing, inject case material, bury one-way valve tube underground, lower nozzle and core pipe segmenting slip casting optionally form at a few step work progresss such as aperture filling accelerating admixtures.Comprise following construction sequence:
(1) inlet well pore-forming, clear hole, injection case material: to the slip casting of cavitation district, according to design slip casting depth requirements, adopts geological drilling rig to be bored into projected depth; When reinforcing existing building ground, first adopt geological drilling rig to drill the former basis of existing building or cushion cap, then according to design slip casting depth requirements, adopt geological drilling rig to be bored into projected depth; When the pile defect of pile foundation or pile bottom force holding layer defect are reinforced, geological drilling rig is first adopted in stake, to carry out drilled drawing-core or hole in stake side, need in stake below drilled drawing-core to defective locations about 1 meter when pile defect is reinforced, about 3 meters need to be required from stake or below stake side drilled drawing-core to complete bearing stratum according to design pile bottom force holding layer to during pile bottom force holding layer defect reinforcing; After pore-forming, high pressure clear water is adopted to carry out rinsing reaming: when reinforcing the pile defect of pile foundation or pile bottom force holding layer defect, first adopt high-pressure rotary-spray mode to spray clear water to rinse defective locations, spray by the technological parameter of design code when spraying clear water, by under Grouting Pipe segmentation at the bottom of hand-hole, churning clear water adopts from below to up, single tube jet grouting mode, and clear water sprays 1 ~ 3 time; When existing building ground is reinforced, can omit and spray this step of clear water; After hole flushing, clear hole, enter sleeve shell material to aperture from hole rising pouring, from the bottom of hole to aperture, 1.5 ~ 2.0m cement paste below last aperture adds suitable quantity of water glass sealing of hole.Fill with sleeve shell material cement (white clay powder) mixing slurry (cement weight is 50%, and white clay powder (swell soil) weight is 50%) to make, water/binder ratio is generally 1:1.This measure needs on-the-spot examination to join, and should have pumpability; After extracting sleeve pipe, after-teeming sleeve shell material is to aperture.
(2) bury Grouting Pipe underground and set up aperture grouting device: case material inject after, under enter one-way valve tube and core pipe thereof, two seal; After set up grouting device at drilling orifice, aperture grouting device adopts mixer type, and mixer type is used for the filling of accelerating admixture;
(3) grouting mode adopts aperture from bottom to top to close incremental extrusion slip casting method.In one-way valve tube, insert 6 be in charge of with the slip casting core of two sealing at the bottom of hole, pour into sleeve shell material after 24 ~ 48 hours (depending on sleeve shell material concentration), slip casting by the bottom of hole, before the slip casting of every hole, first time gives pressure, should check, dredge grouting pipeline by first injected clear water, open loop (sends into thin pulp or clear water institute applied pressure, before filler shell does not destroy by grout pump, pump pressure increases in time, and flow is then always zero.After filler shell destroys, pump pressure rapid drawdown or midge amount increase suddenly, when continuing to apply pump pressure, and the midge situation on stratum during the relation of flow and pressure close non-filler).After the open loop of injection clear water completes, then carry out formal slip casting, open accelerating admixture pipe valve filling accelerating admixture according to actual conditions.Slip casting carries out slip casting by the technological parameter of design code; After reaching the grouting amount of regulation or the pressure of restriction, above propose 2 meters of row slip castings again, circulated layered slip casting like this, until stop slip casting apart from 1.5m place, aperture, slurries spread along crack, to reach the object of slip casting, after slip casting completes, during dismounting slip casting core, prevent remaining slurry from flowing in Grouting Pipe
(4) static pressure grouting mode is adopted to carry out supplementary slip casting: after high-pressure slip-casting terminates, utilize aperture grouting device to seal aperture and carry out static pressure grouting, rarer slurries and lower grouting pressure is adopted when static pressure grouting starts, increase concentration of slurry subsequently gradually and strengthen grouting pressure, till design grouting amount and grouting pressure, general static pressure grouting needs to carry out 2 ~ 3 times and supplements perfusion before slurries final set.
When being described in the utility model specific embodiment, those skilled in the art will recognize that the utility model can be revised in the spirit and scope not exceeding claims.
