Abstract
The invention relates to a construction method for operating a cement-soil compaction pile by a punching vibration compaction method. A kind of compaction pile drill is adopted, a filler is directly filled in a blanking opening on the top of the drill after holes are formed, and a drill body periodically stops vibrating in the sectional filling process, so that hole formation, blanking and compaction coherent construction operation is realized. Under the condition that the original track is not detached, hole formation, feeding and vibration integrated construction is realized, and the whole construction period is shortened, so that construction efficiency is improved.
Description
Technical field
The present invention relates to a kind of cement-soil compaction pile continuity job practices, especially a kind ofly be used for existing track and do not remove ground stabilization and the cement-soil compaction pile continuity job practices of transformation under the prerequisite.
Background technology
At present in the trackage foundation stabilization construction; Tradition compacting pile construction process using respectively pore-forming, fed intake, tamp three steps; Can't under the condition that existing line is not removed, carry out operation; Need to tear open rail, clear tiny fragments of stone, coal, etc. construction, and exist long construction period, step repeatedly, problem such as the constraint based on sites condition is many;
Summary of the invention
The present invention will solve under the condition of not removing original track; Still can accomplish technical problem to the strengthening construction of ground under the track; A kind of job practices that adopts punching vibratory compaction method to carry out the cement-soil compaction pile operation is provided; This method can be eliminated because of the influence to whole foundation stabilization construction of the carrying out of the operation of tearing rail, the clear tiny fragments of stone, coal, etc. open, shortens construction period, improves speed of application.
For solving technical problem of the present invention, the technical scheme that is adopted is following:
A kind of job practices that adopts punching vibratory compaction method to carry out the cement-soil compaction pile operation,
Concrete steps are:
1. installation is mechanical
The hydraulic vibration chuck is connected with the mechanical arm of excavator, clamps the top of compaction pile drill bit again with the hydraulic vibration chuck;
2. clamp-on pore-forming
At existing track construction area along the line the vibrations of compaction pile drill bit are squeezed into and to treat in the soil mass consolidation, and the embedded depth of control compaction pile drill bit;
3. feed intake
With the cement inserts through inserting in the compaction pile of shaping in the feed opening of compaction pile drill bit top;
4. vibrate; Closely knit with carry the pipe pile
Utilize the hydraulic vibration chuck reinforced cementitious inserts successively vibrate in the compaction pile to inserting, closely knit and carry pipe, to compaction pile drill bit bottom ground is proposed fully.
The concrete grammar of clamp-oning control compaction pile drill bit embedded depth in the pore forming process is: on the compaction pile drill bit, put on the absolute altitude control line according to the compaction pile degree of depth, and utilize the embedded depth of the height and position positioning control compaction pile drill bit of absolute altitude control line and existing track.
The invention has the beneficial effects as follows:
It number is 201120486382.5 compaction pile drill bit that the present invention utilizes a kind of utility model patent; Behind pore-forming, directly utilize the feed opening at drill bit top to carry out filler; Simultaneously drill body is at segmentation filler process interval failure of oscillation, thereby realizes limit perforate, limit blanking, the closely knit continuity construction operation in limit.Therefore, the present invention realizes pore-forming, the integrated construction that feeds intake, vibrates under the condition of not removing original track, shortened the integral construction cycle, thereby improves efficiency of construction.

(2) clamp-on pore-forming (Fig. 2)
The Work machine vibrations that will connect compaction pile drill bit 1, excavator 2, hydraulic vibration chuck 3 at existing track 4 construction areas along the line are squeezed into and are treated in the soil mass consolidation 5;
(3) absolute altitude control
On compaction pile drill bit 1, put on the absolute altitude control line, and utilize the embedded depth that concerns positioning control compaction pile drill bit 1 of absolute altitude control line and existing track 4 according to the absolute altitude relation according to compaction pile 9 degree of depth.
(4) manual work feed intake (Fig. 3)
Mix the cement inserts 7 of system according to design and code requirement, 7 manual works of cement inserts are inserted in the pile crown top feed opening 8.
(5) vibrate, closely knit, carry pipe (Fig. 4)
Utilize compaction pile drill bit 1, excavator 2, hydraulic vibration chuck 3 machineries reinforced cementitious inserts 7 successively vibrate in the compaction pile 9 to inserting, closely knit, carry pipe.
(6) carry pile tube and become (Fig. 5)
Compaction pile drill bit bottom 10 is proposed ground fully.
