The grouting anchoring bolt comprises an anchor rod body, as well as a bearing table, a bearing plate and a nut, wherein anchor rod holes are formed on both the bearing table and the bearing plate; the top end of the anchor rod body sequentially penetrate the anchor rod holes on both the bearing table and the bearing plate to be connected with the nut; and a ring-shaped reinforcing cage is arranged on the anchor rod body and at the position within the range of 0.5m-1.5m above and below the position corresponding to a side-slope weak sliding structural face of a rock and earth mass. The grouting anchoring bolt has the advantages of simple structure, convenience in construction and low cost, establishes a novel composite side-slope reinforcing and supporting system of broaching columnar anti-sliding key-adjoining rock crack grouting-anchoring and supporting, realizes comprehensive stereoscopic landslide control taking the sliding plane as the anti-sliding keystone and achieving rock and earth mass reinforcement through an anchor group consisting of a plurality of anchor rods, better arouses the self-stabilizing capability of the rock and earth mass, and improves the side-slope stability and security.
Description
Technical field
The utility model relates to and has clear and definite slide construction face rock and soil slope and reinforce and support technology, relates in particular to reaming column antiskid key slip casting anchoring rod.
Background technology
At present, the side slope no matter natural or hand excavation forms, the Rock-soil Mass Structure face is one of major control factor of its stability, the existence of weak structural plane and feature thereof have conclusive control action for deformation and failure mode and the scale thereof of side slope, the weak structural plane of low-angle dip is especially true, stability to side slope plays absolute control action, because the intensity of weak structural plane is low, cause side slope large deformation and unstability, thereby be the topmost Damage Types of such side slope and controlling object along the structural plane landslide.
Slope and land slide with clear and definite weak slide construction face is typical, the most outstanding, the most largest Landslides in the side slope that forms of natural and hand excavation, for example: very general along the layer rockmass slope bedding slip of inclining, its feature is distinct, in large scale, be difficult to improvement.In decades, the method of preventing and treating and technology for such slope and land slide have obtained very fast development, in mine, the fields such as water conservancy, water power, highway, railway, municipal administration, urban construction, geology, military project obtain extensive use, the vital effect of performance in the national economy Important Project.But existing prevent and treat that method and technology all exist that construction is large to the disturbance of side slope Rock And Soil, engineering quantity is large, length consuming time, cost is high, and the problem such as the skid resistance that can provide is limited, consolidation effect is not ideal enough.Wherein, anchoring is to have one of that commonly used in clear and definite weak slide construction face slope and land slide prevention and cure project, main technical measures, and it,, by being embedded in the anchor pole in stratum, locks together stratum tightly; But it is to provide anchored force traditional anchoring process at all, the slip that anchored force rather than the skid resistance by anchor pole stops side slope indirectly, and the anchored force that can provide is limited, thus not ideal enough to the consolidation effect of side slope.Simultaneously, the rock and soil slope landslide control engineering also is subject to the impact of formation lithology, Rock-soil Mass Structure, geological structure, hydrogeology etc., and may be subject to the violent earthquake effect, and engineering safety is constituted a threat to.
Summary of the invention
Technical problem to be solved in the utility model is to provide and a kind ofly reduces the disturbance of side slope Rock And Soil, optimizes the load pass through mechanism of rock-reinforcing to improve the reaming column antiskid key slip casting anchoring rod of rock and soil slope preventing land slide effect.
For addressing the above problem, reaming column antiskid key slip casting anchoring rod described in the utility model is characterized in that: it comprises anchor rod body and pads platform, backing plate, nut; Be equipped with bolthole on described pad platform and described backing plate; The top of described anchor rod body connects together with described nut through the bolthole of described pad platform and described backing plate successively; Described anchor rod body is provided with the ring steel reinforced bar cage corresponding to supreme the reaching to lower each 0.5m ~ 1.5m scope in the position of the weak slide construction face of rock and soil slope.
The diameter of described ring steel reinforced bar cage is than the little 2mm ~ 5mm in aperture of boring.
The top of described anchor rod body is provided with screw thread.
The utility model compared with prior art has the following advantages:
1, because the weak slide construction face of the corresponding rock and soil slope of anchor rod body in the utility model position to anchor rod body in each 0.5m ~ 1.5m scope up and down is provided with the ring steel reinforced bar cage, and carried out reaming corresponding to the boring section that is provided with the ring steel reinforced bar cage, to the filled slurry of holing, especially to filling slurry in the reaming section that is provided with the ring steel reinforced bar cage and wall-rock crack, when making anchor rod body be anchored in boring, be cast into and take the reaming column antiskid key that reaming section anchor rod body and ring steel reinforced bar cage be reinforcing rib, and the antiskid key is by the injecting cement paste extension of filling in wall-rock crack, thereby traditional anchor pole is mainly relied on to reaming column antiskid key by providing the indirect antiskid of anchored force to change into, the direct antiskid of injecting cement paste in wall-rock crack and the indirect antiskid of anchor pole the system of reinforcing Rock And Soil, realize the right-about of anchor rod anchored mode and academic thought, that is structure reaming column antiskid key-wall-rock crack slip casting-anchoring support NEW TYPE OF COMPOSITE slope reinforcement and support system, the group's anchor formed by many anchor poles, realization be take slide plane as antiskid emphasis the comprehensive three-dimensional preventing land slide that carries out the Rock And Soil reinforcing, transfer better the self-stable ability of Rock And Soil, improve the stability of Rock And Soil, the safety of engineering is strengthened greatly.
2, simple in structure, the easy construction, with low cost of the utility model, can speed up the work significantly.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
