Description
Technical field
The utility model is related to a kind of enlarged footing Pulling-Resistant Anchor Rod, belongs to the ground anchor that soil level sideslope or base pit engineering are reinforced
Bar.
Background technology
Bolt support technology is an important branch in modern age Geotechnical Engineering field, due to it security, economy and
Validity, has been widely used in the every field of social construction.Its deep foundation pit support, stability of slope reinforcing, landslip treatmant,
The development of the aspects such as retaining wall antidumping is quite rapid, and application is also increasingly extensive.Suspension roof support with rely solely on self-strength and weight
Power acts on and makes works keep stable conventional method to compare, and has many unique and salient feature, can open in soil layer
Active support power is provided after digging immediately, is conducive to the inherent strength using soil layer, stop the further disturbance of soil layer, control deformation
Expand and development, improve the security of work progress.
But the current soil bolt adopting, when soil layer intensity deficiency (as drifting sand layer, mud etc.), soil layer is tied with anchor pole
Low with joint efforts, pulling test strength is not enough, Effects of Supporting inconspicuous it is difficult to reach supporting requirement, therefore engineering is in practice because of soil layer
The situation that anchor-holding force of anchor bolt is not enough and produces serious consequence happens occasionally.
Content of the invention
For solving the above problems, the utility model proposes a kind of enlarged footing Pulling-Resistant Anchor Rod, this anchor pole can be passed with effectively solving
The system low technical barrier of anchor-holding force of anchor bolt, and structure is simple, easy construction, Technological Economy are feasible.
Technical solution adopted in the utility model is: enlarged footing Pulling-Resistant Anchor Rod, it by steel enlarged footing, steel pipe, ratchet,
Stop grouting plug, pallet, nut and injected hole composition；The outer end of described steel pipe is provided with external screw thread, the inner end of described steel pipe
It is provided with internal thread, described steel pipe is provided with described injected hole at interval of certain distance；Described ratchet is located at described
Between injected hole and be welded in the outer wall stating steel pipe on；Described steel enlarged footing is located at the inner end of described steel pipe；
Described nut is located at the outer end of described steel pipe；Described pallet is located at the inner side of described nut；Described stop grouting plug position
Inner side in described pallet.
Construction usage method of the present utility model is: in the outer end threading of steel pipe, adds in the inner end of steel pipe
Work internal thread, steel enlarged footing is connected with steel pipe inner end by screw thread, steel pipe sets injected hole every a segment distance, in slip casting
Ratchet is welded with the outer wall of steel pipe between hole, same steel pipe cross section is provided with two to symmetrical ratchet in ten word directions,
Ratchet is formed from middle bending certain angle by steel bar；When soil layer is reinforced, according to engineering specific requirement in assigned position
Accomplish fluently bolthole according to specification, then clear up bolthole again it is ensured that bolthole hole wall must not have heavy quarrel and water body viscous, in cleaning
After complete bolthole, anchor pole is put into bolthole, stop grouting plug is installed in aperture, then in enlarged footing Pulling-Resistant Anchor Rod, injects slurries,
Slurries, by flowing out in injected hole and being injected in the soil layer around anchor pole, install pallet and nut after grout cures.
The beneficial effect of the utility model enlarged footing Pulling-Resistant Anchor Rod is:
1st, the utility model structure is simple, is processed based on steel pipe, makes simple, easy to use；
2nd, the presence of steel enlarged footing makes the anchor force of this enlarged footing Pulling-Resistant Anchor Rod significantly increase, and steel enlarged footing takes
Material is common, low cost；
3rd, on outer wall of steel pipe, the ratchet of setting has certain elasticity tension, and due to its setting direction so that this expansion
Head Pulling-Resistant Anchor Rod can only advance and can not exit, and substantially increase the extraction-resistant behavior of anchor pole；
4th, due to being provided with the injected hole at certain distance interval, make injected hole injection soil layer from each section of steel pipe for the slurries
In, form wavy variable diameters anchoring section, increase the contact area of anchor pole and the soil body, significantly improve anchor pole and the soil body
Adhesion.
