Feature of the invention and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing, with
Convenient for the understanding of technical staff of the same trade：
Such as Fig. 1-6, label 1-21 is respectively in figure：Grouting pipe 1, rubber ring 2, upper steel plate 3, lower steel plate 4, casing 5, set
Pipe 6, external screw thread 8, grout outlet 9, steel pipe 10, slurry outlet 11, doughnut-shaped steel plate 12, preformed hole 13, ring flange 14, is reserved pressure valve 7
Hole 15, side wing 16, bolt hole 17, bolt 18, nut 19, pull rod 20, nut 21.
Embodiment：As shown in Figure 1, 2, several slurry outlets 11 are offered in the lower part of steel pipe 10, for 10 periphery of steel pipe
The soil body carries out slip casting to form injecting cement paste, with 10 collective effect of steel pipe to undertake bigger load；To prevent to steel pipe
It generates during 10 slip casting and returns slurry phenomenon, the present embodiment specifically provides a kind of steel pipe high-pressure slip-casting with preventing returning paste-making method.
As shown in Figs. 1-5, steel pipe high-pressure slip-casting is returned paste-making method and is included the following steps with anti-in the present embodiment：
（1）Coaxial arrangement is expanded for the only rubber ring 2 of slurry and for squeezing rubber ring 2 in grouting pipe 1
Elastic regulating part, wherein：
Rubber ring 2 has certain thickness and elasticity, and outer diameter is slightly less than the internal diameter of steel pipe 10, i.e., uses between the two
Clearance fit, so that convenient be inserted into steel pipe 1O before slip casting and do corresponding position adjustment；
Elasticity adjusting mechanism includes being fixedly installed on the support platform of 2 lower section of rubber ring and being movably set in rubber ring 2
The rotary compressing member of top；Support platform above-mentioned is set to below rubber ring 2 and is used as counter-force support platform, by coaxial
The casing 5 and coaxial arrangement being fixed in grouting pipe 1 are formed in the lower steel plate 4 on casing 5, and lower steel plate 4 is close to rubber
The lower surface of ring 2 provides it supporting role, and outer diameter is slightly less than the outer diameter of rubber ring 2；Rotary compressing member above-mentioned
It is successively formed from bottom to top by being coaxially disposed in upper steel plate 3, casing 6 and the pressure valve 7 in grouting pipe 1, upper steel plate 3 is tight
The upper surface setting of rubber ring 2 is pasted, outer diameter is slightly less than the outer diameter of rubber ring 2, movable between casing 6 and grouting pipe 1
For transmitting 7 pressure applied of pressure valve to upper steel plate 3, pressure valve 7 is matched with the external screw thread in grouting pipe 1 for connection,
It can transmit extruding force to rubber ring 2 through casing 6 and upper steel plate 3 during being rotated down；
（2）Grouting pipe 1 is inserted into certain depth in the steel pipe 10 of slip casting, which can make rubber ring 2 be located at steel pipe
In 10 and pressure valve 7 is located at except steel pipe 10, at this point, being in clearance fit between 10 inner wall of rubber ring 2 and steel pipe；
（3）Pressure valve 7 is rotated down by the external screw thread 8 on 1 vertical direction of grouting pipe manually, and pressure valve 7 pushes up downwards
Pushing sleeve pipe 6, casing 6 compresses upper steel plate 3, so that pressure is transferred on rubber ring 2, lower steel plate 4 is used as support platform at the same time
To rubber ring 2 provide reaction of bearing, rubber ring 2 after being squeezed around expansion expand, thus make its in steel pipe 10
Wall fits closely, and constitutes interference fit, to improve only slurry sealing performance；
（4）Performance is only starched in order to further increase the pressure-bearing of rubber ring 2, is arranged between grouting pipe 1 and steel pipe 10 and connects
The outer drawing mechanism of assembled for connecing the two, so that the limit for carrying out vertical direction to grouting pipe 1 and rubber ring 2 is fixed, specifically
Method is：
By two halves circular flange to spelling on the outer wall of steel pipe 10, the Mosaic face of semicircle ring flange has side wing 16, side
Bolt hole 17 is provided on wing plate 16, two halves circular flange is inserted into bolt 18 and is passed through in bolt hole 17 after alignment is assembled
Nut 19 tightens fixation, to make 14 band tightener of ring flange due in the outside wall surface of steel pipe 10；It is spaced and opens up on ring flange 14
There are four groups of preformed holes 15；
Expose to one doughnut-shaped steel plate 12 of coaxial welding on the part except steel pipe 10 in grouting pipe 1, outer diameter with
14 outer diameter of ring flange is corresponding, and is spaced apart in the outer edge of doughnut-shaped steel plate 12 and is equipped with four groups of preformed holes 13, preformed hole 13
Open up position and preformed hole 15 open up position one-to-one correspondence；
Both ends are had into threaded pull rod 20 successively vertically through preformed hole 13 and preformed hole 15, are being drawn respectively later
The both ends of bar 20 screw in nut 20 and are locked, with realize the locking between doughnut-shaped steel plate 12 and ring flange 14 to drawing, also
It is to say, grouting pipe 1 and the rubber ring 2 being arranged on are limited in vertical direction, even if carrying out in steel pipe 10 high
Upward displacement will not occur for pressure grouting, rubber ring 2；
（5）1 top of grouting pipe is connected into Grouting Pipe, high-pressure slip-casting, during slip casting, rubber ring are carried out into steel pipe 10
2, which fit closely 10 inner wall of steel pipe, prevents slurries, and the outer drawing mechanism of assembled provides vertical limit to rubber ring 2 and grouting pipe 1
Position, prevents under the action of high pressure slurries, and rubber ring 2 is moved by jacking；
（6）After to slip casting, the external screw thread 8 in grouting pipe 1 unscrews pressure valve 7 upwards, discharges for rubber ring 2
Extruding force, make its reinstatement, grouting pipe 1 and rubber ring 2 pulled away into steel pipe 10, be applied to next steel pipe in.
It should be noted that it is not restricted for the quantity of rubber ring 2 in the present embodiment, as shown in fig. 6, being stopped
When slurry, double-layer rubber ring 2 can also be set in grouting pipe 1 and be further lifted in steel pipe to constitute dual baffle
Only starch performance.
