Description
Technical field
The utility model relates to a kind of slip casting sleeve valve pipe that is used for the correcting and then reinforcing of ground stabilization processing and treatment of soft foundation and building.
Background technology
At present, aspect the reinforcing of construction work, as the correcting and then reinforcing of ground stabilization processing and treatment of soft foundation and building, the bracing means complex structure of its use, the construction technology complexity, inconvenient operation, and cost and cost height use very uneconomical.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of slip casting sleeve valve pipe is provided, and this sleeve valve tubular structure is simple, and easy construction, occupied ground is few, consolidation effect good, to overcome the complex structure that prior art exists, deficiencies such as inconvenient operation.
The technical scheme that the utility model adopted is: it comprises slip casting A pipe and slip casting B pipe, slip casting A pipe is inner at slip casting B pipe, slip casting A pipe is provided with grouting tube section and the joint with two stop grouting plugs, and slip casting B pipe is provided with slurry discharging hole, and its termination is provided with the taper plug.
Be with rubber sleeve valve pocket outside the slurry discharging hole on slip casting B pipe.
Slurry discharging hole is spaced apart 0.6～1m on slip casting B length of tube, evenly lay on the circumference, and quantity is 6～12, and diameter is φ 6～φ 8mm.
Be provided with 3～4 in the contact-segment of the plunger of slip casting A pipe and stop grouting plug and only starch rubber cup.
Construction is divided into boring, inserts slip casting B pipe, inserts grouting valve A pipe, sealing of hole, 5 steps of slip casting, can depthkeeping in the construction, quantitatively, carry out branch preface, segmentation, gap and repetition slip casting, combine fracture grouting method, close slip casting method of pressure (squeezing) and the advantage of infiltrating slip casting method.Do not offer the slurry hole of overflowing on the slip casting A pipe, have the slurry discharging hole of φ 6～φ 8mm on the B kind Grouting Pipe.Manage outside, porose position at slip casting B and overlapping the rubber sleeve that anti-burst pressure is 4.5MPa tightly, rubber sleeve is covered with slurry discharging hole, like this, during slip casting, slurries can enter the stratum by slurry discharging hole, and water in the stratum and particle are difficult to enter in the Grouting Pipe, thereby reach the one way valve effect of Grouting Pipe.The floral tube section of slip casting B pipe can adopt steel pipe or pvc pipe, lays the slurry discharging hole of 6～12 φ 6～8mm around generally long 0.6～1m equably.Only starch rubber cup for 3～4 about having in the floral tube section bottom scope of slip casting A pipe,, play only slurry effect to form the plasma resistance plug.Slip casting A pipe adopts steel pipe processing, and the long 2～4m of every joint takes screwed connection between tube coupling.
The utlity model has up and down two stop grouting plugs, slurries can be limited in arbitrary segment limit in slip casting zone and carry out slip casting, reach the purpose of segmenting slip casting.
Stop grouting plug can move freely in smooth sleeve valve pipe, as required a certain section repeatedly slip-casting in the slip casting zone.
Needn't establish thicker concrete before the slip casting and end the magmatic rock wall, emit the possibility of slurry, string slurry little when taking bigger grouting pressure.
Can in a Grouting Pipe, adopt different slip casting according to stratum characteristic, select for use different grouting parameters to carry out mortar depositing construction.
Boring, slip casting can take the parallel operations mode, and boring and injected hole spacing distance be generally suitable＞6 m, increase work efficiency.
The utility model is simple in structure, and cost of manufacture is low, easy construction, and consolidation effect is good, the economic benefit height.

The specific embodiment
Embodiment of the present utility model: it comprises slip casting A pipe and slip casting B pipe, slip casting A pipe 4 is in the inside of slip casting B pipe 2, left side section among slip casting A pipe 4(such as Fig. 1) is provided with grouting tube section 7 and joint (8) with two stop grouting plugs 6, slip casting B pipe 2 is provided with slurry discharging hole 5, and its termination is provided with taper plug 1.
Be with rubber sleeve valve pocket 3 outside the slurry discharging hole 5 on slip casting B pipe 2.
Slurry discharging hole 5 is managed the 0.6～1m that is spaced apart on 2 length at slip casting B, evenly lays on the slip casting B pipe circumference, and quantity is 6～12, and diameter is φ 6～φ 8mm.
Be provided with 3～4 in the contact-segment of the joint 8 of slip casting A pipe 4 and stop grouting plug 6 and only starch rubber cup.
Stop grouting plug 6 is the step stop grouting plug.
During construction, boring can be adopted geology brill, hidden hole drilling or water jetting pore-forming.Sleeve pipe retaining wall water jetting drilling and forming hole, drilling depth should reach grouting reinforcement section height.According to the slip casting requirement, in the B of slip casting position mounting strap injected hole pipe floral tube section, non-slip casting position is installed not short with the real pipe of B pipe of injected hole.Grouting Pipe B is inserted in the inlet well, guarantee under the Grouting Pipe that at the bottom of the hole, the top is above ground level.Add stifle down in the slip casting A that connects pipe bottom, slowly, insert in the slip casting B pipe by joint.Slip casting A pipe injects the space that the sealing of hole slurries are filled expires between the slip casting B pipe and the soil body after being inserted into slip casting B pipe bottom, and the sealing of hole slurries adopt low intensive slurries, generally adopt the match ratio of cement: swell soil=1:2, in mass ratio (being weight ratio).After the sealing of hole slurries injected, topped up with water in slip casting B pipe was utilized action of gravity, and slip casting B pipe can not floated, and afterwards slip casting A pipe was proposed lentamente, at last stifle on slip casting B pipe upper cap.After slip casting A pipe is extracted, sentence employing accelerated cement mortar shutoff down at ground 1m.The sealing of hole slurries inject and could to inject the reinforcing slurries after 48 hours, and the segmentation injection mode is taked in slip casting, and every section slip casting length is called the slip casting step pitch, and the slip casting step pitch is identical with slurry discharging hole step pitch on the slip casting B pipe.Grouting pressure, grouting amount are determined according to different geology and groundwater table, generally calculate grouting amount control slip casting effect with the void ratio of geology in the construction.The slip casting step pitch is 0.6～1m, can reduce the influence of stratum inequality to slip casting effect effectively like this.In the slip casting process, after every section slip casting is finished, move up or down core barrel (A pipe) length of a step pitch.The employing lifting means moves, or manually adopts 2 pipe wrench symmetries to clamp core barrel, and evenly firmly, move core barrel (A pipe) simultaneously both sides.Whenever finish 2～4m slip casting length, the joint slip casting core barrel of dismantling.After slip casting finishes, go out the slurries of B pipe, on the B pipe, cover stifle, so that annotate construction again with clear water.
