Detailed description of the invention
Below in conjunction with concrete case study on implementation, the utility model is described as follows: as the one of an embodiment of the present utility model based on bowlder stone, the simple and easy sleeve valve grouting device on Thief zone coefficient stratum, as shown in Figure 1, comprises grouting pump 1, mini-valve tube 2, slip casting core pipe 3 and sleeve shell material 9, slip casting core pipe 3 is arranged in mini-valve tube 2, slip casting core pipe 3 according to slip casting need in position establish injected hole 5, mini-valve tube 2 arranges one at interval of certain distance and penetrates slurry hole 7, slurry hole 7 penetrated by rubber case 4 parcel, section slip casting core pipe 3 being arranged injected hole is slip casting section, the two ends of slip casting section arrange block pulp piston 6, pass through slip casing by pressure, slurries and the periphery soil body 8 are interacted, and form injecting cement paste 10, this structure construction is convenient, effect is obvious, has concentrated fracture grouting method, the advantage of pressure (squeezing) close slip casting method and permeation grouting method, can carry out depthkeeping, quantitatively, divide sequence, segmentation, intermittently, repeat slip casting, ground adaptability is strong, to bowlder stone, Thief zone coefficient stratum can reach good slip casting effect, effectively reinforces soil layer, suitably improves bearing capacity of foundation soil, and adjacent injecting cement paste interpenetrates, densification, occlusion, can also play sealing effect.Wherein, the caliber of described mini-valve tube 2 is not more than 60mm, the caliber of described slip casting core pipe 3 is not more than 40mm, sleeve shell material is cement, clay and the water system of stirring form, its reference formulation is cement: clay: water=1:1.5:1.9(weight ratio), field trial should be carried out, to determine the reasonability of sleeve shell material parameter in practice of construction.Described spacing of penetrating slurry hole 7 is not less than 30cm, described rubber case, 4 is that often group penetrates the outer wrap 1-2 layer rubber case in slurry hole, and also welds to locate ring on the both sides of rubber case, its diameter is about 5mm, and grout coordinate ratio, grouting pressure and flow are chosen respectively according to Different Strata.
This device, pours into a mould sleeve shell material after needing pore-forming in hole, closes the annulus between mini-valve tube and drill hole wall, when preventing from being in the milk, slurries flee hither and thither, under the cooperation of rubber sleeve valve and stop grouting plug, force slurries only to fill with open loop in segment limit at one, rack sleeve shell material and enter stratum.Slurries make slurries and the soil body interact by modes such as infiltration, densification, splittings, abundant combination forms cement-soil induration and the dendroid cement net arteries and veins body of higher-strength, improve the performance of the soil body, soil body self-stable ability and non-deformability are greatly increased.Its operating principle as shown in Figure 2.
In the present embodiment, mini-valve tube 2 is the pvc pipe of Φ 40, and slip casting core pipe 3 adopts Φ 30 steel pipe, often saves length 1m, penetrates slurry hole 7 spacing 33cm, wraps up with double-deck rubber case 4, and locates ring in two side welds of rubber case 4 with diameter 5mm.For bowlder stone, high permeability formation, adopt cement---silicate double solution grouting, water/binder ratio 0.6-0.7, grouting pressure 0.6MPa-2MPa, single flow rate of grouting 150L-200L.
In sand-pebble layer, adopt band sleeve pipe jumbolter (being commonly called as water drilling) vertical drilling to projected depth, sediment in boring is cleaned out rear cast sleeve shell material 9, bury slotting mini-valve tube 2, in mini-valve tube 2, insert slip casting core pipe 3, after reaching open-loop standards, carry out slip casting according to design and technological requirement segmentation from bottom to top.Grout coordinate ratio, grouting pressure and grouting amount are suitably chosen according to strata condition.
Based on the simple and easy sleeve valve grouting device on bowlder stone, Thief zone coefficient stratum, compared with the measure of the soil stabilization such as rotary churning pile, cement mixing method, its construction costs can save about 50%, for various different soil layers such as silty clay, clay, Extra-fine sand gravel, silty, siltstone, gravelly sand and fragmented rock bodies, also there is stronger compliance, and can need carry out secondary or repeatedly repeat slip casting according to construction.Simultaneously its speed of application be churning, 2 times of cement mixing method, construction machinery small volume, constructs convenient, effectively can save the duration.
