Description
Technical field
The utility model relates to a kind of Counterboring apparatus, more specifically to a kind of anchor hole bottom hole Counterboring apparatus belongs to
Anchorage technology field.
Background technique
Soil anchor bolt is the soil layer internal drilling that do not excavate in deep foundation Tu Bi, after reaching certain depth, be put into hole reinforcing bar,
The materials such as steel pipe, steel tendon, steel strand wires pour into mud or chemical grout, and so that it is combined into tension with soil layer, (to pull out) power strong
Anchor pole.
Currently, having no the soil anchor bolt for anti-floating, Traditional project realizes this function using anti-floating pile.But anti-floating pile
It is larger compared to soil anchor bolt boring aperture, and its bottom not reaming, single anti-floating pile ultimate pullout capacity are less than soil anchor bolt；While at
This is also above soil anchor bolt, it is difficult to satisfy the use demand.
Summary of the invention
The purpose of this utility model is that and its bottom larger compared to soil anchor bolt boring aperture for existing anti-floating pile
The problems such as not reaming, provides a kind of anchor hole bottom hole Counterboring apparatus.
To achieve the above object, institute is the utility model using technical solution: a kind of anchor hole bottom hole Counterboring apparatus,
Including turnbarrel, turnbarrel is arranged in anchor hole, water injection conduit is provided in the turnbarrel and the conduit that draws water,
It is provided with rubber stopper between turnbarrel lower part outer wall and anchoring hole wall, the water injection conduit bottom is connected with sparge pipe, institute
The sparge pipe outlet stated is water jet, and sparge pipe is fixed on turnbarrel by Rotatable bracket, and sparge pipe can be led around water filling
Pipe rotation.
The sparge pipe angle rotatable is 15-45 °, when which is sparge pipe rotation and between ground level vertical line
Angle, four rotation gears are arranged in the Rotatable bracket, this four rotation gears respectively correspond can be rotated for sparge pipe
15 °, 25 °, 35 ° and 45 ° of angle.
The water injection conduit and the conduit that draws water is fixed in turnbarrel by fixed bracket.
Compared with prior art, the beneficial effects of the utility model are:
It is small and easy for construction using this anchor hole bottom hole Counterboring apparatus boring aperture, it is relatively inexpensive.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is sparge pipe rotation figure one in the utility model.
Fig. 3 is sparge pipe rotation figure two in the utility model.
In figure, turnbarrel 1, water injection conduit 2, draw water conduit 3, rubber stopper 4, sparge pipe 5, Rotatable bracket 6, fixed branch
Frame 7.
Specific embodiment
The utility model is described in further detail below in conjunction with Detailed description of the invention and specific embodiment.
Referring to Fig. 1 to Fig. 3, a kind of anchor hole bottom hole Counterboring apparatus, including turnbarrel 1, the setting of turnbarrel 1 are being anchored
Kong Zhong, turnbarrel 1 can in anchor hole 360 degree rotation；It is provided with water injection conduit 2 in the turnbarrel 1 and draws water
Conduit 3 is provided with rubber stopper 4 between 1 outer wall of turnbarrel lower part and anchoring hole wall, and rubber stopper 4 plays sealing function.Described
2 bottom of water injection conduit is connected with rotatable sparge pipe 5, and the outlet of sparge pipe 5 is water jet, and sparge pipe 5 is by can be rotated
Bracket 6 is fixed on turnbarrel 1, and sparge pipe 5 can be rotated around water injection conduit 2.
Referring to Fig. 1 to Fig. 3, further, 5 angle rotatable of sparge pipe is 15-45 °, which is sparge pipe 5
Angle when rotation between ground level vertical line；Four rotation gears, this four rotation shelves are arranged in the Rotatable bracket 6
Position respectively corresponds 15 °, 25 °, 35 ° and 45 ° of angle rotatable of sparge pipe 5.
Referring to Fig. 1 to Fig. 3, specifically, the water injection conduit 2 and the conduit 3 that draws water, which pass through fixed bracket 7, is fixed on rotation
In sleeve 1.
Referring to Fig. 1 to Fig. 3, when this Counterboring apparatus pore-forming, is first bored using geology or hidden hole drilling beats anchor hole straight hole, then general
Water injection conduit 2 and the conduit 3 that draws water pass through fixed bracket 7 and are fixed in turnbarrel 1, make water injection conduit 2 and 3 bottom of conduit of drawing water
Stretch out turnbarrel 1；Turnbarrel 1 is placed in anchor hole straight hole again.Then water injection conduit 2 and external high pressure water pipe are connect
Logical, will draw water conduit 3 and the connection of external high pressure water pump, cuts anchor hole bottom hole inner wall by 2 jet stream of water injection conduit, uses simultaneously
High-pressure hydraulic pump extracts hole bottom slurry by the conduit 3 that draws water.4 energy of rubber stopper between 1 outer wall of turnbarrel lower part and anchoring hole wall
It enough prevents from gushing out between 2 jet stream of water injection conduit cutting anchor hole bottom hole inner wall Shi Shuicong turnbarrel and hole wall, erosion damage rubber
4 or more hole walls are filled in, collapse hole is caused.Then to high-pressure jet pin hole after, keep high-pressure hydraulic pump pass through draw water conduit 3 persistently take out
Hole bottom slurry is taken, is stopped until high-pressure hydraulic pump goes out after cement slurry volume is reduced.Adjust the height of water injection conduit 2 finally to realize tune
The angle of whole Rotatable bracket 6, such method facilitate the extraction of turnbarrel 1；Then entire turnbarrel 1 is taken out, i.e., it is complete
At soil anchor bolt anchor hole bottom hole chambering process, subsequent soil anchor bolt implantation technique can be carried out.Also, it is cut in 2 jet stream of water injection conduit
When anchor hole bottom hole inner wall, can successively by Rotatable bracket 6 be adjusted to one grade of corresponding sparge pipe 5 15 ° of positions of angle rotatable,
25 ° of positions, 35 ° of positions, 45 ° of positions, while slowly rotation turnbarrel 1 rotates it 1-2 weeks, and high-pressure hydraulic pump is made to extract bottom
Mud in portion hole；Until anchor hole bottom hole inner wall forms, terminate high-pressure jet pin hole.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, above structure
It all shall be regarded as belonging to the protection scope of the utility model.
