Description
Technical field
The utility model relates to the construction fields of drilled pile, clear more particularly, to a kind of cast-in-situ bored pile tremie
Cleaning device.
Background technique
During drilled pile construction, tremie, which does not wash clean clearly, this may result in residual concrete on its inner wall,
Remaining concrete has solidified when reusing, and blocks fresh concrete.Cleaning of the construction site to tremie at present
Mode is fairly simple, is rinsed merely by man-hour manually hand-held water pipe against conduit cavity or put in conduit cavity；It is this
Original cleaning way water consumption is bigger, and cannot be guaranteed disposably to clean up, and also needs cleaning worker in coagulation sometimes
The both ends of native conduit are cleaned repeatedly, considerably increase the working time, reduce working efficiency.In addition, once can not be primary
If property cleans up tremie, the concrete for remaining in pipe inner wall may block fresh concrete, cause to pacify
Total quality hidden danger.
Summary of the invention
The utility model aim is to provide that a kind of structure is simple, installation and uses easy cast-in-situ bored pile concrete
Catheter cleaning devices.
To achieve the above object, the utility model can take following technical proposals:
Cast-in-situ bored pile described in the utility model tremie cleaning device, including removable cover are put in concrete and lead
The end cap of pipe upper end is provided with the annular edge that gap is plugged in the tremie on the lower surface of the end cap；
Sealing is equipped with the jet pipe of lower end closure at the center of the end cap, and the upper end of the jet pipe is provided with hose joint,
Lower end extends in the tremie inner cavity below the annular edge, uniformly interlocks on the jet pipe tube wall below end cap
Offer several bar shaped notch tilted upward.
The inner sidewall for being close to the annular edge is distributed along the circumference with several support rods, and the support rod extends vertically downward
To the jet pipe.
Anti-skidding rough surface is provided on the outer wall of the hose joint.
The utility model advantage is that structure is simple, installs and using easy.The present apparatus is placed in the concrete of extraction
Conduit upper end, and hose is connected on hose joint, it is drawn water by small pump, is sprayed water into tremie, had
Effect ground utilizes hydraulic pressure and gravity, keeps tremie cleaning more convenient and thorough, guarantees construction quality, shortens clear
It washes the time, saves manpower, improve working efficiency；In addition, present apparatus processing cost is very low, it can also Reusability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the perspective view (concealing tremie) of Fig. 1.
Fig. 3 is the usage state diagram of the utility model.
Fig. 4 is the portion A enlarged drawing in Fig. 3.
Specific embodiment
As shown in Figure 1, 2, cast-in-situ bored pile described in the utility model tremie cleaning device, including removable cover
It is put in the end cap 2 of 1 upper end of tremie, end cap 2 is the circular steel plate of diameter 380mm, thickness 2mm, with existing concrete
Conduit 1 is adapted；It is provided with the annular edge 3 that gap is plugged in tremie 1 on the lower surface of end cap 2, makes end cap 2
Left and right offset will not occur when lid is put in 1 upper end of tremie or fall；It is sealed at the center of end cap 2 under being equipped with
The jet pipe 4 of end closure, the upper end of jet pipe 4 are provided with hose joint 5, are connected with external hose, connect to improve hose
Fastening force when connector 5 is connect with hose is provided with anti-skidding rough surface on the outer wall of hose joint 5；Under jet pipe 4
End extends in 1 inner cavity of tremie of annular 3 lower section of edge, uniformly interleaved on 4 tube wall of jet pipe of 2 lower section of end cap
Equipped with several bar shaped notch 6 tilted upward；It is to lead in cleaning concrete that 4 lower end of jet pipe, which extends to below annular edge 3,
When pipe 1, on the inner wall that the water energy sprayed from bar shaped notch 6 enough ensures to be directly sprayed onto tremie 1, and bar shaped notch 6 interlocks
It is more uniform in order to spray water for opening up, it is ensured that water can be sprayed onto the inner wall circumferential direction of tremie 1, bar shaped notch 6 tilts
It is upward then be the inner wall upper end in order to which water to be sprayed onto tremie 1 as far as possible, it is ensured that rinse thorough.
In addition, will necessarily generate certain pressure in inner cavity in hydroblasting tremie 1, which is easy
End cap 2 is caused to be jacked up upwards, to make end cap 2 be unlikely to be washed out by hydraulic pressure, the inner sidewall for being close to annular edge 3 is evenly distributed
There are several support rods 7, support rod 7 extends to 4 lower section of jet pipe vertically downward, and when end cap 2 has slightly been rushed, support rod 7 is always
In 1 inner cavity of tremie, under gravity, end cap 2 can also cover again is pressed on 1 upper end of tremie.
It is as shown in Figure 3,4 when use, firstly, the present apparatus is covered in 1 upper end of tremie to be pulled out, and in jet pipe
A plastic flexible pipe 8 is connected on the hose joint 5 of 4 upper ends, the length of plastic flexible pipe 8 is depending on the concrete condition at scene, and one
As be 15m, the other end of plastic flexible pipe 8 install a power be 1KW, the small pump 9 that lift is 10m, water pump 9 is placed in Sheng
Have in the bucket 10 of 200L clear water；Then, tremie 1 is extracted by crane upwards and arrives specified altitude assignment (specified altitude assignment
It is obtained by the concrete height reckoning in drilling in in-site pouring Concrete, general primary extraction 5M long)；Later, it works
Personnel dismantle tremie 1, the two section concrete conduits 1 to link together are dismantled, and hung the conduit of dismounting by crane
To specified cleaning positions, notice that the conduit being pulled out needs to be suspended from ground 30cm or so；Later, it opens water pump 9 to switch, water quilt
It guides jet pipe 4 into, is influenced by hydraulic pressure, (bar shaped notch 6 is equivalent to spray for ejection in the bar shaped notch 6 that water can be opened up from jet pipe 4
The mouth of a river), be sprayed onto the 1 inner wall upper end of tremie of suspension, under the gravity of water itself, along 1 inner wall of tremie to
Lower flowing makes being flushed from top to bottom of remaining concrete in it；In cleaning process, the bottom of tremie 1 is visible
The color for being rinsed object (mixed with the muddy water of concrete) is gradually faded away, until becoming clear water just calculates completion cleaning, whole process is only
Need 5s or so；After the completion of to be cleaned, storage position specified at the scene is stacked by the tremie 1 that crane finishes cleaning,
The cleaning device is removed at this time to put to designated position, when extracting next section tremie 1, is repeated above operation.
