Description
Technical field
This utility model belongs to Geotechnical Engineering reinforcement technique field, relates to soil bolt conventional in a kind of soil-slope or foundation ditch strengthening engineering, particularly relates to a kind of Detent-type soil anchor rod.
Background technology
Soil bolt be a kind of be arranged in boring, the end reinforcing bar that stretches in steady soil or steel strand wires and the tension body of rod of injecting cement paste composition in hole, have that low cost, consolidation effect be good and the advantage such as easy construction, be widely used in the various soil layer reinforcing engineerings such as soil level sideslope, pattern foundation pit supporting structure, retaining wall, diaphram wall, abutment reinforcing.
Soil bolt common in soil layer reinforcing engineering at present is simple due to version, when soil layer intensity is more weak, soil property is soft, anchor bolt construction pore-forming difficulty, and anchoring body is relatively low with the binding ability of soil layer, breakout capacity is poor, the phenomenon that anchor pole is extracted from boring together with anchoring body and anchor pole is extracted from anchoring body happens occasionally, and while bringing hidden danger to engineering safety, also governs application and the development of soil layer anchorage technology.For overcoming the deficiency of tradition soil bolt, patent CN 203320527 A discloses a kind of Detent-type soil anchor rod, this anchor rod body is provided with steel wire ratchet, has the feature that can not exit of can only advancing, substantially increase anchor pole anti-pulling ability and with the adhesion of soil layer；Lever front end is processed to conical closure hat formula, can directly can not be in the soil property Loose Slope soil layer of pore-forming by anchor pole injection by modes such as impact drill or artificial hammerings.But steel wire ratchet itself has certain elasticity tension, during by direct for anchor pole injection loose soil bed, steel wire ratchet can deform under the effect of soil layer resistance and loses original shape, the aperture of steel wire ratchet diminishes and anchor force can be caused to weaken, do not have improve anchor pole breakout capacity and with the effect of soil layer adhesion.
As can be seen here, prior art needs further to be improved.
Summary of the invention
A kind of Detent-type soil anchor rod being possible to prevent steel wire ratchet to deform that the purpose of this utility model is aiming at the above-mentioned problems in the prior art and provides.
A kind of anti-deformation Detent-type soil anchor rod described in the utility model, including steel pipe, steel wire ratchet, anti-deformation nut, stop grouting plug, pallet and fixing nut；Described steel pipe total length is machined with external screw thread, and on steel pipe, interval is disposed with perforation and grout hole, and frustum of a cone form is processed in steel pipe front end；Above-mentioned is distributed by " ten " font on steel tube section perforation；Described anti-deformation nut is the round nut with four grooves, and it is screwed in the side of steel pipe rear end close to perforation through steel pipe；Above-mentioned groove is distributed on four end points of round nut；Described steel wire ratchet is formed to the steel bar warpage passed perforation by two, and the steel bar correspondence after warpage is stuck in four grooves of anti-deformation nut；Described stop grouting plug, pallet and fixing nut is positioned at the rear end of steel pipe.
Reinforce can not the soil property of pore-forming loose soil level sideslope time, by the mode of hydraulic drill rig or directly hammering, anti-deformation Detent-type soil anchor rod is pushed in soil layer, stop grouting plug is installed in aperture, and in anti-deformation Detent-type soil anchor rod, inject serosity, the hole wall gap that serosity flows out from each grout hole and is full of around anchor pole, installs pallet fixing nut of screwing on after grout cures.
This utility model has the advantage that
1, owing to being provided with anti-deformation nut, during direct for anchor pole injection loose soil bed is reinforced, anti-deformation nut is supplied to the support force of steel wire ratchet can be with balanced action soil layer resistance on steel wire ratchet, prevent steel wire ratchet excessive deformation from losing original design aperture, it is ensured that steel wire ratchet can give full play to it and improves anti-pulling of anchor bar and strengthen the effect with soil layer adhesion.
2, being provided with screw thread due to steel pipe total length, when nut stress, screw thread is prevented from nut and moves, and can also improve the frictional force between steel pipe and anchoring body simultaneously, and the phenomenon reducing slip occurs.
3, this utility model anchor pole principle is simple and clear, installation procedure is simple and convenient to operate.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
A kind of anti-deformation Detent-type soil anchor rod as shown in Figure 1, it includes steel pipe 1, steel wire ratchet 2, anti-deformation nut 3, stop grouting plug 4, pallet 5 and fixing nut 6.It can be seen that described steel pipe 1 total length is machined with external screw thread from Fig. 1 and Fig. 2, on steel pipe, interval is disposed with perforation 7 and grout hole 8, and frustum of a cone form is processed in steel pipe 1 front end；Above-mentioned is distributed by " ten " font on steel tube section perforation 7；Described anti-deformation nut 3 is the round nut with four grooves 9, and it is screwed in perforation 7 near the side of steel pipe rear end through steel pipe 1；Above-mentioned groove 9 is distributed on four end points of round nut；Described steel wire ratchet 2 is formed to the steel bar warpage passed perforation 7 by two, and the steel bar correspondence after warpage is stuck in the groove 9 of anti-deformation nut 3；Described stop grouting plug 4, pallet 5 and fixing nut 6 is positioned at the rear end of steel pipe 1.
Reinforce can not the soil property of pore-forming loose soil level sideslope time, by the mode of hydraulic drill rig or directly hammering, anti-deformation Detent-type soil anchor rod is pushed in soil layer, stop grouting plug 4 is installed in aperture, and in anti-deformation Detent-type soil anchor rod, inject serosity, serosity flows out and is full of the hole wall gap around anchor pole from each grout hole 8, installs pallet 5 fixing nut 6 of screwing on after grout cures.
