The slurries of outflow are limited in the space at the place of slip casting part 72 to realize orienting slip casting.By outwards extracting or being inwardly put into height
The length of the defeated slurry flexible pipe 5 of pressure can control slip casting inner tube 6 to be slid up and down along the length direction of Grouting Pipe, so that orientation slip casting
The diverse location that device 7 rests on Grouting Pipe carries out slip casting.
Grout pile bottom stake side post grouting process is comprised the following steps：
S1：With reference to Fig. 1 and Fig. 4, cast-in-situ bored pile 9 is constructed：
（1）Drill and borehole cleaning：Stake holes 81 is drilled through using drilling machine at the stake position of base soil layer 8 first, in boring procedure
Ensure that the perpendicularity in hole meets design requirement, after drilling reaches design requirement depth, reply hole depth, hole position, hole shape, aperture etc.
Checked.Whole hole check comply fully with design requirement when, bottom hole cleaning should be carried out using suction dredge immediately, it is to avoid every when mistake
Length is so that mud sediment, causes borehole collapse.
（2）Precast reinforced cage 91 and colligation Grouting Pipe：According to the steel reinforcement cage 91 needed for the prefabricated bored concrete pile of design requirement, will
The body 1 of Grouting Pipe is tied up firmly along the length direction of cage bar 911 of steel reinforcement cage 91, and causes the slip casting shower nozzle 2 of bottom termination
Grow the bottom of steel reinforcement cage 91, the body 1 of top termination is higher by bored concrete pile top surface to be made, and top the termination of body 1 and list
Use polyethylene film to cover to control valve 11 to prevent from blocking.Then on demand at the middle part of bored concrete pile to be made on steel reinforcement cage 91
Position is accurately installed by annular slurry casting machine 4 so that flexible pipe 43 is set in the periphery of steel reinforcement cage 91, flexible pipe 43 along steel reinforcement cage 91 circle
Week sets and is fixed with iron wire, to prevent the displacement of flexible pipe 43.
（3）Lay steel reinforcement cage 91 and concrete conduit：During the steel reinforcement cage 91 for tying up Grouting Pipe is hung onto stake holes 81, installation course
It is middle to notice that protection Grouting Pipe is not damaged by, then from the placed on top concrete conduit of steel reinforcement cage 91.
（4）Perfusion pile body：By concrete tremie placing concrete, after concrete enters steel reinforcement cage 91, concrete rises should not be too fast, and concrete conduit exists
Buried depth is unsuitable excessive in concrete, unsuitable too fast during lifting concrete conduit in strict accordance with Authority Contro1 between 2-6m, prevents concrete conduit
Hook steel reinforcement cage 91 and brought up.Because concrete can not be combined completely with base soil layer 8, therefore cast-in-situ bored pile 9 and base soil
Can there is gap 82 between layer 8.
S2：Treat that bored concrete pile completes 3 days grouting behind shaft or drift lining：
（1）Preparation：Remove for protecting the polyethylene film of the top port of body 1 and one-way control valve 11, and open
One-way control valve 11 is switched；The defeated slurry flexible pipe 543 of high pressure is connected with slip casting inner tube 6 and ensures sealing joint, slip casting inner tube 6
And orientation slurry casting machine 7 is inserted into Grouting Pipe and is deep into bottom so that orientation slurry casting machine 7 is supported to slip casting shower nozzle 2.
（2）Pile grouting：By the defeated slurry conveying high-pressure cement grout of flexible pipe 543 of high pressure, high pressure cement slurries are through in slip casting
Pipe 6 flow to orientation slurry casting machine 7, can ensure that now cement grout is only filled with slip casting bottom of the tube in the presence of wedge-shaped rubber ring 71.
Because the stainless steel tube wall of slip casting shower nozzle 2 is in rigidity, the protecting film being coated on outside injected hole 221 has elasticity, therefore cement mortar
Liquid passes through injected hole 221 and breaks through protecting film and flow in a bottom gap 822 under high pressure.Treat that pile grouting amount reaches design requirement
Or grouting pressure is when reaching design load, pile grouting work is completed.
（3）Slip casting around pile：After the completion of pile grouting, outwards the defeated slurry flexible pipe 543 of lifting high pressure causes that slip casting inner tube 6 is promoted to
Slip casting around pile region, orients the three-way pipe 1 on the slip casting part 72 and Grouting Pipe of slurry casting machine 7 in same confined space, starts
Slip casting is oriented to stake side, now cement grout is full of annular slurry casting machine 4, because the compressive property of flexible pipe 43 is compared with protecting film
Good, cement grout breaks through protecting film under high pressure carries out secondary splitting to the concrete on bored concrete pile top layer, so as to flow to a latasuture
In gap 821.Because flexible pipe 43 is to surround steel reinforcement cage 91 to set, therefore cement grout can be filled up equably around grout pile side
Gap 82, when slip casting around pile amount reaches design requirement or grouting pressure reaches design load, slip casting around pile work complete.Stop
The conveying of cement grout, slip casting inner tube 6 is extracted, and closes one-way control valve 11 to block Grouting Pipe, completes whole slip casting work.
To sum up, by above-mentioned grout pile bottom stake side post grouting process, it is possible to achieve single Grouting Pipe is completed to bored concrete pile
Stake bottom, stake side grouting behind shaft or drift lining work, improve a side skin friction, bearing capacity of pile tip, reach shorten stake it is long, reduce sedimentation effect
Really.Because the medium position of Grouting Pipe can increase the quantity of annular slurry casting machine according to the length of Grouting Pipe, therefore can be to filling
The different depth of note stake stake side carries out slip casting respectively, improves slip casting around pile effect.Simultaneously as the quantity of Grouting Pipe is reduced,
The workload for tying up Grouting Pipe is reduced in construction, efficiency of construction is improve, and save consumptive material.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
Should be regarded as protection scope of the present invention.
