Pressure-bearing effect, people's generally use injection cement slurry, but be formed into cement slurry and need supporting Mixing Machine and big
The manpower and materials of amount, and it is of long duration, operating efficiency is low, be this it is proposed that a kind of high pre-stress anchor pole with expansion sleeve.
Utility model content
The purpose of this utility model is to provide a kind of high pre-stress anchor pole with expansion sleeve, to solve above-mentioned background technology
Traditional anchor pole of middle proposition needs anchor pole squeezing into foundation ditch when in use, and resistance is larger when squeezing into foundation ditch, in order to increase anchoring
The bonding rubbing action of body and soil layer and the pressure-bearing effect for increasing anchoring body, people's generally use injection cement slurry, but make
Need supporting Mixing Machine and substantial amounts of manpower and materials into cement slurry, and it is of long duration, operating efficiency is low the problem of.
To achieve the above object, the utility model provides following technical scheme：A kind of high pre-stress anchor pole with expansion sleeve,
Including the body of rod, supporting plate and expansion sleeve, the outer wall right side opening of the body of rod is provided with screw thread, and the supporting plate is spirally connected with screw thread, the support
The right side of plate is provided with fixing bolt, and the fixing bolt is spirally connected with screw thread, and the interior of the body of rod is provided with cavity, the expansion sleeve set
It is connected on the left of the outer wall of the body of rod, the left side of the body of rod is provided with head, and the outer wall of the body of rod is uniformly provided with sawtooth, the head
Left side be provided with bar point, the inner chamber of the supporting plate is provided with input duct, and the right side inwall of the cavity is provided with inlet, described
Inlet is connected with input duct.
Preferably, the head is reverse wedge shape, and the maximum gauge of head is more than endoporus maximum gauge when expansion sleeve expands.
Preferably, the sawtooth is the gradual change sawtooth that gradually increases, and minimum two groups of positions it is corresponding sawtooth both ends it is straight
Linear distance is more than the maximum gauge of head.
Preferably, the bar point is welded in the left side outer wall of head.
Compared with prior art, the beneficial effects of the utility model are：Noted during use by giant to input duct
Enter water under high pressure, water under high pressure flows to inlet by input duct, then flows into cavity, and water under high pressure expands the body of rod, extrudes foundation ditch
Hole wall country rock, great frictional force is produced, the body of rod is firmly embedded in foundation ditch by sawtooth, pass through bar point and sawtooth
It is engaged, it is possible to reduce anchor pole squeezes into resistance caused by foundation ditch, and when the insertion body of rod meets obstructions, expansion sleeve is opened by head
Power expands expansion sleeve, expansion sleeve expand when wrap head, can be significantly greatly increased with hole wall caused by frictional force, this practicality newly
Type is rational in infrastructure, easy to use, can greatly improve operating efficiency.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
In figure：1 body of rod, 2 screw threads, 3 supporting plates, 4 fixing bolts, 5 cavitys, 6 expansion sleeves, 7 heads, 8 sawtooth, 9 bars point, 10 are entered
Liquid pipe road, 11 inlets.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of high pre-stress mooring rod technique scheme with expansion sleeve：A kind of band expansion
The high pre-stress anchor pole of set, including the body of rod 1, supporting plate 3 and expansion sleeve 6, the outer wall right side opening of the body of rod 1 is provided with screw thread 2, described
Supporting plate 3 is spirally connected with screw thread 2, and the right side of the supporting plate 3 is provided with fixing bolt 4, and the fixing bolt 4 is spirally connected with screw thread 2, the bar
