Therefore, the middle part 10 of the periphery of cylindrical tube and part 11 and its facing surfaces between total interval that has a minimum.
Crosspiece 15 generally is fixed on the stator 24, and 24 of stators are fixed on the middle part 10 of part 11.
Crosspiece 15 preferably with each oil cylinder 13 cooperating, and be fixed on oil cylinder 13 directly over so that limit the action that makes guider 11,12 become comparatively approaching mutually of oil cylinder.
One plate 16 for example by screw and nut device 16 detachables the relative side of groove that be fixed on part 11 and that be used for holding cylindrical tube 12 10.The length of plate 16 equals the length of part 11, thereby can seal this part.Plate 16 can have various width, and this depends on the width of the groove 1 of preparing build.Therefore can fully change the sealing joints of plate 16 with the partition wall of production different-thickness.
Plate 16 also comprises guiding device 18, is used for to boring pick device such as scraper bowl or topping machanism guiding.
As shown in Figure 4, cylindrical tube 12 comprises a closure plate 23 in its lower end, basically form one with pipe 12 fore-and-aft tilt so that make device drive in the plane on ground 3.
The wall portion 21 of the lower end of close cylindrical tube 12 can move between an open position and a make position, and when above-mentioned make position, the inside of pipe 12 can be isolated with a kind of mode and external world of sealing.
One check plate 22 also is fixed on the lower end of cylindrical plate 12, thereby the load on the pipe 12 can be mentioned when withdrawing from device.
Describe below and use said apparatus pack into the method for two-phase abut groove of seal nipple.
See also Fig. 1, when the partition wall in the build ground 3, in ground 3, use common device to dig out first groove 1 as pick wall scraper bowl or topping machanism.
Groove 1 generally fills out with swell soil in case the subsiding of ground around the groove 1 that digs.
In prior art shown in Figure 1, at least one end of groove 1 uses separating device 2 isolated with ground 3, and separating device 2 is generally cylindrical long tube.
Then, pour into concrete seven by concrete pipe 4, pipe 4 makes concrete seven insert the bottom of the groove 1 under the swell soil, thereby groove 1 is filled from the bottom, and swell soil 6 is upwards released groove 1.
Then, 3 excavations, second groove makes it be adjacent to first groove 1 on ground, then by crane gear, before injecting concrete to adjacent groove, removes separating device.
Like this, build the partition wall that the adjacent grooves by a series of variable-lengths constitutes.
In the method according to the seal nipple of packing into of the present invention, separating device 2 is by above-mentioned replacing according to device of the present invention.
The vertical edge 14b of seal nipple 14 is clipped between two guiding devices 11,12, be more strictly speaking to be clipped in two opposed facing two 11a of wall portion, between the 12a, this be owing to oil cylinder 13 work make guiding device 11,12 mutually near and realize.
Therefore two seal nipples 14 can be positioned between the guider 11,12.
Spacing crosspiece 15 stops the motion of cylindrical tube 12, is damaged by pressure to avoid seal nipple 14.
As shown in Figure 3, if only adorn a sealing, so, 14 of seal nipples are replaced by a shim 20 identical with its thickness, and this can make, and cylindrical tube 12 is positioned at the center in part 11, shim 20 preferably is fixed on the part 11.
Be clipped in seal nipple 14 between the guider 11,12 and have one and freely indulge edge 14a, come out from 11,12 projections of two guiders.Then, two guiders of clamping seal nipple 14 are inserted in the one or both ends of the groove 1 that digs out in the ground 3.
In aforesaid operations, the wall portion 21 of the lower end of close pipe 12 keeps opening wide, so that make the swell soil in the groove 1 can continue to enter in the pipe 12.
This helps device is driven in groove 1.
Thereby concrete seven is set in freely indulging around the edge 14a of seal nipple 14.By guider 11 and 12 and be fixed on plate 16 on the part 11, concrete remains in the groove 1, and part 11 closes the end of groove 1 and prevent that concrete seven from flowing around device in the mode of sealing.
Then, be adjacent to two guiders 11,12 excavate second groove 1 ', as shown in Figure 3.
The pick wall scraper bowl that is used for excavated earth 3 can be contained on the guiding device 18 and by its guiding, 18 of guiding devices are fixed in plate 16.These guiding devices 18 for example can be similar to guide rail, are placed on highlightedly on the plate 16, as in the present embodiment, perhaps are provided with respect to plate 16 retractions.
Then, at least one is moved in the guider 11,12, makes these two guiders be in the position of separating, thus the nipped vertical edge 14b of pine oil seal nipple 14.
Drive a series of oil cylinders 13 in order to accomplish this point.Because these two guiders are fixed by concrete seven in first groove, 1 one sides, thus the separating action of each oil cylinder 13 make part 11 be pushed rearward to second groove of excavating 1 '.
After the above-mentioned motion, device only contacts on little of cylindrical tube 12 side faces with concrete seven, and the position of this part is with respect to the part 11 between two seal nipples 14.
In addition, by plate 16 groove 1 and the concrete of the new injection in its end are isolated in the mode that seals, thereby concrete can not be flowed by winding apparatus.
Because concrete seven is attached to the surface area of device and is restricted on the sub-fraction of cylindrical tube 12, therefore, help using the crane gear discharge equipment.
In according to method of the present invention, after guider 11,12 being positioned on its position of separating, preferably guider 11,12 is placed on it near on the centre position between position and its position of separating.
With other direction driving oil cylinder 13 so that make guider 11,12 close mutually.
In general, because plate 16 is held in place by the groove of adjacency, the close action of guider that makes of oil cylinder 13 can make cylindrical tube 12 shift to part 11, thereby can make pipe 12 break away from concrete seven.
Therefore device can be taken out without a doubt, cylindrical tube 12 no longer is attached to concrete seven, and seal nipple 14 is then in the stand-down 3, and fixing on the throne by the concrete that pours into first groove 1.
Then, with concrete seven pour into second groove 1 ', these concrete sevens are fixed another vertical edge 14b of seal nipple 14.
Like this, when concrete seven pours into 1,1 ' time of groove, seal nipple 14 just assembles not difficultly and does not finish.
Certainly, can make various changes and not exceed scope of the present invention the foregoing description.
For example, the middle part 10 of W shape part 11 can and be sealed by a continuous slab truncation, thereby makes continuous slab constitute the retainer of another guider 12, and this continuous slab only has opening at oil cylinder 13 places of passing.
On the other hand, can the end some seal nipples 14 be placed on ground, end, so that on the height of the needs of partition wall, realize sealing.Contrast with it also can only be placed a seal nipple, and a shim identical with seal nipple 14 thickness is fixed on the longitudinal component of not establishing seal nipple 14 of part 11 on a part of height of groove 1.
Obviously, hydraulic jack can be replaced by any telecontrol equipment that other is equal to.
According to device of the present invention, without seal nipple, also can use in the same old way, that is to say, just as a kind of at the groove of excavating with cast modified separating device between the concrete ground.
