Abstract

The utility model provides reverse circulation hole forming equipment for a cast-in-place pile, which has strong adaptability to the soil layer and has large hole forming depth. The reverse circulation hole forming equipment for the cast-in-place pile comprises a hydraulic motor, a drill rod and a drive rod, wherein the drill rod and the drive rod are connected with the hydraulic motor; a drill bit is arranged at the lower end of the drill rod; the drive rod is connected with the hydraulic motor through a rotating table disk; the upper end of the drive rod is connected with a slurry pump through a vacuum hose; a slurry settling tank is arranged at the lower end of the slurry pump; and the slurry settling tank is communicated with a drill hole. The reverse circulation hole forming equipment for the cast-in-place pile has strong adaptability to the soil layer from soft soil to sand and gravel, or even the rock stratum. Compared with the hole forming depth of a normal circulation mode and a slurry static mode, the hole forming depth of the reverse circulation hole forming equipment is greatly improved and can reach 100m.

Description

The anti-pore-forming equipment that circulates of castinplace pile
Technical field
The utility model relates to a kind of filling pile construction equipment, the anti-pore-forming equipment that circulates of especially a kind of castinplace pile.
Background technology
Castinplace pile is to use more a kind of type, because its noise is little, little to ambient influnence, diameter up 3~4m, bearing capacity are much larger than driven pile, and these advantages make the development prospect of castinplace pile generally good by engineering circle.But the accident resulting from poor quality of projects of castinplace pile is more, has also caused the execution control of numerous technician's attention, especially castinplace pile really.
For high altitude localities such as Qinghai-Tibet Plateans; Receiving the wider pouring pile hole mode of the present application of influence of weather conditions such as the high height above sea level in plateau, low pressure, geological conditions is mechanical hole building castinplace pile and manually digging hole filling pile; Single with regard to the mechanical hole building castinplace pile, what Qinghai-Tibet Platean application at present was more is the technology of grabbing the static pore-forming of soil bucket mud, direct circulation method pore-forming.But the limitation of its plasma discharge mode also has restriction to the character of soil layer, is applicable to the very thin flour sand of particle, clay, and depth of pore forming is about 30m.
It is mechanical hole building and manually digging hole that more pore-forming technique is used in the filling pile construction operation of Qinghai-Tibet Platean district; Be limited by the influence of topography and geomorphology, weather conditions and construction team's level, the main application technology of mechanical hole building castinplace pile is static construction of mud and direct circulation construction technology at present.
For mud sleep mode pore-forming, along with the increase of depth of pore forming, constantly in the hole, replenish fresh mud, till placing of concrete cemented out mud, mud stored in the hole always.During the direct circulation pore-forming, mud and dregs overflow from the aperture, rely on gravity to flow into sedimentation basin, also can by mud nearby the stock pump in the pond deliver in the farther sedimentation basin, the mud after the dilution reinjects in the hole to keep the absolute altitude of mud face in the hole again.
No matter the mud sleep mode still is the direct circulation mode; Its plasma discharge mode is a passive state, and limitation is big and speed is slower, and the character of soil layer is also had restriction; Be applicable to the very thin flour sand of particle, clay, depth of pore forming is generally (part, saturated soft soil area can reach 60m) about 30m.
The utility model content
The utility model provides a kind of compliance to soil layer strong, the darker anti-pore-forming equipment that circulates of castinplace pile of depth of pore forming.
Realize the anti-pore-forming equipment that circulates of castinplace pile of the utility model purpose; Comprise hydraulic motor, the drilling rod and the drive link that link to each other with said hydraulic motor; The lower end of said drilling rod is provided with drill bit, and said drive link links to each other with said hydraulic motor through the turntable dish, and the upper end of said drive link links to each other with slush pump through vacuum hose; Said slush pump lower end is provided with slurry sediment pool, and said slurry sediment pool communicates with boring.
Be provided with the slag absorbing flexible pipe between said vacuum hose and the drilling rod.
Said slush pump is provided with cold rinse bank, and said cold rinse bank links to each other with hydraulic motor through pipeline.
The beneficial effect of the anti-pore-forming equipment that circulates of the castinplace pile of the utility model is following:
The utility model is more intense to the compliance of soil layer, and from the weak soil to the sand pebble layer even the rock stratum, depth of pore forming calibration endless form and mud sleep mode are greatly improved, and can reach 100m.
Description of drawings
Fig. 1 is the structural representation of the anti-pore-forming equipment that circulates of the utility model castinplace pile.
The specific embodiment
As shown in Figure 1; The anti-pore-forming equipment that circulates of the castinplace pile of the utility model comprises hydraulic motor 1, the drilling rod 2 and the drive link 5 that link to each other with said hydraulic motor 1, and the lower end of said drilling rod 2 is provided with drill bit 3; Said drive link 5 links to each other with said hydraulic motor 1 through turntable dish 4; The upper end of said drive link 5 links to each other with slush pump 10 through vacuum hose 7, and said slush pump 10 lower ends are provided with slurry sediment pool 9, and said slurry sediment pool 9 communicates with boring.
Be provided with slag absorbing flexible pipe 6 between said vacuum hose 7 and the drilling rod 2.Said slush pump 10 is provided with cold rinse bank 8, and said cold rinse bank 8 links to each other with hydraulic motor 1 through pipeline, is used for cooling fluid pressure motor 1.
During the anti-circulation pore-forming of the utility model, mud is from hole wall and 2 injections of drilling rod, and the mud of band dregs is discharged by slush pump 10, and until slurry sediment pool 9, waste pulp refills the use hole in after treatment.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
