Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is slip casting sleeve valve tubular structure schematic diagram;
Fig. 2 is slip casting sleeve valve pipe grouting and reinforcing schematic diagram.
The specific embodiment
With reference to Fig. 1～Fig. 2, a kind of slip casting sleeve valve pipe, it comprises slip casting A pipe and slip casting B pipe, described 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.Particularly, described stop grouting plug 6 is the step stop grouting plug,
Be further used as preferred embodiment the slurry discharging hole 5 outer rubber sleeve valve pockets 3 that are with on the described slip casting B pipe 2.
Be further used as preferred embodiment, described 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 circumference, and quantity is 6～12, and diameter is φ 6～φ 8mm.
Be further used as preferred embodiment, the joint 8 of described slip casting A pipe 4 is provided with several with the contact-segment of stop grouting plug 6 and only starches rubber cup.Particularly, the described rubber cup quantity of only starching is 3～4.
Construction is divided into boring, inserts slip casting B pipe 2, inserts slip casting A pipe 4, 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 4, have the slurry discharging hole 5 of φ 6～φ 8mm on the slip casting B pipe 2.Manage outside, 2 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 5, like this, during slip casting, slurries can enter the stratum by slurry discharging hole 5, 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 2 can adopt steel pipe or pvc pipe, lays the slurry discharging hole 5 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 4,, play only slurry effect to form the plasma resistance plug.Slip casting A pipe 4 adopts steel pipe processing, and the long 2～4m of every joint takes screwed connection between tube coupling.
Before the slip casting, needn't establish thicker concrete 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.
With reference to Fig. 2, 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, manage 2 floral tube sections at the slip casting B of slip casting position mounting strap injected hole 5, the installation of non-slip casting position is not managed 2 real pipeline sections with the slip casting B of injected hole 5.Slip casting B pipe 2 is inserted in the inlet wells, guarantee under the Grouting Pipe that at the bottom of the hole, the top is above ground level.Manage 4 bottoms at the slip casting A that connects and add down stifle, slowly, insert in the slip casting B pipe 2 by joint.Slip casting A pipe 4 is inserted into after slip casting B manages 2 bottoms, injects the sealing of hole slurries and fills space between the full slip casting B pipe 2 and the soil body, 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 2 was utilized action of gravity, and slip casting B pipe 2 can not be floated, and afterwards slip casting A pipe 4 was proposed lentamente, managed stifle on 2 upper caps at slip casting B at last.After slip casting A pipe 4 is extracted, sentence employing accelerated cement mortar shutoff down at ground 1m.The sealing of hole slurries inject could inject after 48 hours reinforces slurries, 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 5 step pitches that slip casting B manages on 2.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, form stabilization zone 11 and positive stabilization zone 12.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.
More than be that better embodiment of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
