Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of PHC tubular pole anti-freeze expansion processing unit, to a certain degree
The upper mass deviation and project cost reduced when PHC tubular pole anti-freeze expansion is constructed.
A kind of PHC tubular pole anti-freeze expansion processing unit, it is characterised in that: including hollow drilling pipe, the hollow drilling pipe lower end is opened
Mouth setting, is installed with helical blade around its outer wall in the hollow drilling pipe.
Further are as follows: the hollow drilling pipe upper end is sealed set, and the center in the hollow drilling pipe upper surface is solid
Equipped with connector, the connector, which is used to connect, provides the drive system of rotary force.
Further are as follows: the helical blade is installed at the middle part of the core drill drum outer wall and lower part, described hollow
The top of drilling pipe successively offers several holes of being unearthed from top to bottom.
Further are as follows: it is installed with the native plate of sweeping of the vertical hollow drilling pipe on the top of the hollow drilling pipe, it is described to sweep soil
Plate is angle steel, and is fixedly connected by welding with the hollow drilling pipe.
The utility model has the beneficial effects that utility model device structure is simply easy to use, manufacturing cost is low；Practical
Utility model is avoided that increasing reserved change of PHC tubular pole length or subdrilling macropore fills out non-frost heave material space and construct again PHC tubular pole, from
And reduce project cost.

Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
As depicted in figs. 1 and 2, a kind of PHC tubular pole anti-freeze expansion processing unit, including hollow drilling pipe 5, the hollow drilling pipe 5
Lower ending opening setting, is installed with helical blade 3 around its outer wall in the hollow drilling pipe 5.
5 upper end of hollow drilling pipe is sealed set, is installed with connection in the center of hollow 5 upper surface of drilling pipe
Part 2, the connector 2, which is used to connect, provides the drive system of rotary force.
Specifically, the helical blade 3 is installed at the middle part of hollow 5 outer wall of drilling pipe and lower part, described hollow
The top of drilling pipe 5 successively offers several holes 5 of being unearthed from top to bottom.
It is installed with the native plate 1 of sweeping of the vertical hollow drilling pipe 5 on the top of the hollow drilling pipe 5, it is described to sweep native plate 1 as angle
Steel, and be fixedly connected by welding with the hollow drilling pipe 5.
It is the use step of the utility model in conjunction with shown in Fig. 3 and Fig. 4:
Step 1: by hollow 5 loop of drilling pipe on the PHC tubular pole B to have constructed；
Step 2: making the hollow drilling pipe 5 along the PHC tubular pole B, C is rotated below to the ground, at this time the helical blade
3 precession is directed downward；
Step 3: being continued to rotate after so that 5 lower end of hollow drilling pipe is parked in ground C certain depth below, pass through the spiral shell
Soil around the PHC tubular pole B is turned to ground C or more by vane piece 3；
Step 4: when the helical blade 3 being located at ground is no longer unearthed, taking out the hollow drilling pipe 5 upwards；Make
There are the filled layers of tubular around the ground C PHC tubular pole B below；
Step 5: being filled in the filled layer and tamp non-frost heave material.
In the step 4, when taking out the hollow drilling pipe 5 upwards, the hollow drilling pipe 5 is reversely rotated.
The utility model General Implementing process is as follows:
One, hollow boring bit is made
It is made according to PHC tubular pole diameter dimension using seamless steel pipe or other rigid materials more slightly larger than PHC tubular pole hollow
Drilling pipe (causes the distortion of PHC tubular pole to destroy) when size being avoided closely to be rotated down；Two sides are opened in two sides above hollow drilling pipe
Shape hole, so as to the unearthed hole as soil extra in hollow drilling pipe；An angle steel is welded above hollow drilling pipe, as sweeps soil
Plate facilitates and the soil routed up is put down；
Helical blade outside hollow drilling pipe needs material identical with steel pipe model, to guarantee helical blade and hollow drilling pipe
It combines closely, helical blade will be fully welded with hollow drilling pipe, to guarantee that utility model device possesses enough rigidity, in any soil
Desired effect is attained by the case of matter；
Two, hollow drilling pipe and backacter are assembled
It is assembled by the driving rotary head of the connector and backacter of hollow drilling pipe upper end.
Three, it checks mechanical
After the acceptance(check) of construction site, set drills through check whether each component and instrument are sensitive effectively after native machine is marched into the arena, really
Protecting equipment operation safety can use after normal.
Four, set drills through soil
Hollow drilling pipe is inserted on the PHC tubular pole constructed, machinery start slowly be rotated down, with hollow drilling pipe to
Reverse rotation when lower rotation and extraction, soil can be turned to earth's surface with helical blade, two sides of two sides above hollow drilling pipe
Shape hole so as to the unearthed hole as soil extra in hollow drilling pipe, and sees whether to reach the absolute altitude for changing the demand of filling out；In hollow drilling pipe
Angle steel at top facilitates and the soil routed up is put down.
Five, it changes and fills out non-frost heave material
It takes to change after soil around PHC tubular pole below ground using utility model device and fills out non-frost heave material, using
Pressure rams the compacting factor for reaching design and related specification requirement.
