The sleeve pipe 8 being located in Grouting Pipe 1 and the backing plate 7 and 9 laying respectively in sleeve pipe 8 both ends of the surface, the length of sleeve pipe 8 is according to slip casting chamber
Body Len req determines, it should be noted that in order to not stop the slurry outlet in Grouting Pipe 1, sleeve pipe 8 uses framework to construct；(c)
Rotary compressing member is arranged at the top of rubber shrouding 6, including pressure valve 3, sleeve pipe 4 and backing plate 5, at the outer wall of Grouting Pipe 1
On there is one section of external screw thread 2, pressure valve 3 has the female thread suitable with aforementioned external screw thread 2, thus constitutes spiral shell with Grouting Pipe 1
Stricture of vagina is connected, and sleeve pipe 4 and backing plate 5 are all the most sheathed with Grouting Pipe 1 movable, and pressure valve 3 is during being rotated down
Thrust can be produced.
As shown in Figure 1,5, the method for work of the present embodiment middle tube body segmenting slip casting structure comprises the steps:
(1) as it is shown in figure 1, steel pipe 10 down, is pressed into the designated depth to the soil body by pile top；
(2) as it is shown in figure 1, the upper port of Grouting Pipe 1 to be connected outside grouting equipment；
(3) as it is shown in figure 1, the pressure valve 3 in Grouting Pipe 1 is upwards unscrewed, so that two rubber shroudings in Grouting Pipe 1
6 and 13 can be matched in clearance with the inwall of steel pipe 10 during pressure down；The end of lower pressure grouting pipe 1 to steel pipe 10, steel pipe 1
Within the slurry outlet 11 being distributed on end tube wall is in the close range of two rubber shroudings 6 and 13；After Grouting Pipe 1 is in place,
Being spinned down by pressure valve 3, two rubber shroudings 6 and 13 expand to circumference after by thrust, thus with steel pipe 10
Inwall constitutes interference fit, and the Grouting Pipe 1 position in steel pipe 10 keeps fixing；
(4) as shown in Figure 1,5, the outside grouting equipment of unlatching is to Grouting Pipe 1 inner high voltage slip casting, and serosity is in Grouting Pipe 1
Slurry outlet is spurted into and is enclosed in the slip casting cavity constituted by two rubber shroudings 6 and 13, rear slurry by going out on steel pipe 10
Slurry hole 11 is spread in the outside soil body, thus forms pile end grouting enlarged footing 23 in the end of steel pipe 10；
(5) as shown in Figure 1,5, after the construction of pile end grouting enlarged footing 23 to be done, pressure valve 3 is upwards unscrewed, so that
Two rubber shrouding 6 and 13 external diameter resiliences, recover the clearance fit relationship between steel pipe 10 inwall；Upwards lifting Grouting Pipe 1 to
Slip casting around pile fragment position, the slurry outlet 11 that 10 side pipe walls of steel pipe are distributed is in the closing model of two rubber shroudings 6 and 13
Within enclosing；After Grouting Pipe 1 is the most in place, again being spinned down by pressure valve 3, two rubber shroudings 6 and 13 are by thrust
Backward circumference expands, thus constitutes interference fit with the inwall of steel pipe 10, and the Grouting Pipe 1 position in steel pipe 10 keeps solid
Fixed；
(6) as shown in Figure 1,5, the outside grouting equipment of unlatching is to Grouting Pipe 1 inner high voltage slip casting, and serosity is in Grouting Pipe 1
Slurry outlet is spurted into and is enclosed in the slip casting cavity constituted by two rubber shroudings 6 and 13, rear slurry by going out on steel pipe 10
Slurry hole 11 is spread in the outside soil body, thus forms slip casting around pile enlarged footing 22 at the middle part of steel pipe 10；
(7) as shown in Figure 1,5, after the construction of slip casting around pile enlarged footing 22 to be done, pressure valve 3 is upwards unscrewed, so that
Two rubber shrouding 6 and 13 external diameter resiliences, recover the clearance fit relationship between steel pipe 10 inwall, the most upwards lift Grouting Pipe
1 leaves steel pipe 10 completes construction.
Embodiment 2: as shown in Figure 2-5, the present embodiment is specifically related to a kind of body segmenting slip casting being applicable to high-pressure slip-casting
Structure, this segmenting slip casting structure is with the difference of segmenting slip casting structure in embodiment 1: also include the outer drawknot of an assembled
Structure 16, the position that the outer pull-up structure 16 of this assembled can fix Grouting Pipe 1 further prevents it to be shifted over during slip casting
Situation.
As in Figure 2-4, the outer pull-up structure of this assembled is used for fixing Grouting Pipe 1 and two rubber shroudings 6 and 13 thereon
Position, including the ring flange 19 being fixed on steel pipe 10 outer wall and the doughnut-shaped steel plate 17 being fixedly welded in Grouting Pipe 1, two
It is fixed to realize zip through some pull bars 18 between person, wherein: ring flange 19 coaxial welding is fixed in the outside wall surface of steel pipe 10, when
Can also be so by two semicircle ring flanges to spell banding in the outside wall surface of steel pipe 10, the outer ring of ring flange 19 interval offer
There are some through hole 20 wearing for pull bar 18；Doughnut-shaped steel plate 17 is fixedly welded on the portion outside Grouting Pipe 1 exposes to steel pipe 10
On Fen, its external diameter and through hole 21 set on it and the external diameter of ring flange 19 and through hole 20 one_to_one corresponding, by by pull bar
18 run through through hole 20 and through hole 21 and through nut screwing clamping locking thus realize the locking between doughnut-shaped steel plate 17 and ring flange 19
Fixing, the outer drawing mechanism of this assembled spacing under, Grouting Pipe 1 and two rubber shroudings 6 and 13 are equal when bearing high-pressure slip-casting
Will not be shifted over.
