Description
Technical field
The present invention relates to and there is the rock and soil slope reinforcing of clear and definite slide construction face and support technology, particularly relate to olive-shaped antiskid key slip casting anchoring support explosion pipe anchor rod.
Background technology
At present, the no matter side slope that formed of natural or hand excavation, Rock-soil Mass Structure face is one of major control factors of its stability, the existence of weak structural face and feature thereof have conclusive control action for the deformation and failure mode of side slope and scale thereof, the weak structural face of low-angle dip is especially true, absolute control action is played to the stability of side slope, because the intensity of weak structural face is low, cause side slope large deformation and unstability, thus coming down along structural plane is the topmost Damage Types of such side slope and controlling object.
The slope and land slide with clear and definite weak slide construction face is natural and Landslides typical, the most outstanding, the most largest in the side slope of hand excavation's formation, such as: very general along layer rockmass slope bedding slip of inclining, its signature, in large scale, be difficult to administer.In decades, obtain for the prevention and controls of such slope and land slide and technology and develop faster, in mine, water conservancy, water power, highway, railway, municipal administration, urban construction, geology, the field such as military project obtain extensive use, in national economy Important Project, play vital effect.But existing prevention and controls and technology all also exist that construction is large to the disturbance of side slope Rock And Soil, engineering quantity is large, length consuming time, cost are high, and the problem such as the skid resistance that can provide is limited, consolidation effect is not ideal enough.Wherein, anchoring be to have in the slope and land slide prevention and cure project of clear and definite weak slide construction face commonly use, one of main technical measures, stratum, by burying anchor pole in the earth formation underground, locks together by tightly; But traditional anchoring process its be to provide anchored force at all, indirectly provide skid resistance to side slope by the anchored force of anchor pole, and the anchored force that can provide is limited, thus not ideal enough to the consolidation effect of side slope.Meanwhile, rock and soil slope landslide control engineering is also subject to the impact of formation lithology, Rock-soil Mass Structure, geological structure, hydrogeology etc., and may be subject to the effect of violent earthquake, constitutes a threat to engineering safety.
Summary of the invention
Technical problem to be solved by this invention is to provide the loading transfer mechanism of a kind of reduction to the disturbance of side slope Rock And Soil, optimization rock-reinforcing to improve the olive-shaped antiskid key slip casting anchoring support explosion pipe anchor rod of rock and soil slope preventing land slide effect.
For solving the problem, olive-shaped antiskid key slip casting anchoring support explosion pipe anchor rod of the present invention, is characterized in that: it comprises both ends open, the tubular type body of rod of hollow and baffle ring and backing plate; The top of the described tubular type body of rod is filled stemming and is provided with the described baffle ring of the described backing plate of band; It is supreme and be circumferentially dispersed with the multiple axial grooves penetrating tube wall at equal intervals to lower each 0.5m ~ 1.5m that the described tubular type body of rod corresponds to the weak position, slide construction face of rock and soil slope; The cylindrical explosive that detonator is housed is provided with in the described tube wall being dispersed with the described tubular type body of rod of described axial groove; Described detonator is connected with detonator payment to a porter.
The present invention compared with prior art has the following advantages:
1, be circumferentially dispersed with within the scope of each up and down 0.5m ~ 1.5m that there is position, clear and definite weak slide construction face due to the corresponding rock and soil slope of the tubular type body of rod in the present invention penetrate tube wall at equal intervals axial groove built with cylindrical explosive.First, the blast of cylindrical explosive, produce strong effect to tube wall, make tubular type body of rod generation plastic strain, cause tube wall radial dilatation diameter to increase, the tube wall section making the tubular type body of rod be dispersed with axial groove is pushed open into olive-shaped; They are two years old, the detonation gas that the blast of cylindrical explosive produces, to the impact compress consumingly of the Rock And Soil on drill hole wall, causes hole wall Rock And Soil to be pulverized, and the more radial pressurized of the Rock And Soil of depths, hoop tension and broken, form drill hole wall Rock And Soil destruction to a certain degree, form blast pit; Its three, the weak slide construction face of the detonation gas that the blast of cylindrical explosive produces to rock and soil slope produces strong effect, and the crack degree in slide strips and sliding bed Rock-soil Mass Structure face is increased and slide plane structural change.Thereupon, slurry is filled with boring in tubular type body of rod tube wall, especially in the outer olive-shaped blast pit that formed of tube wall and wall-rock crack, slurry is filled to cylindrical explosive blast, the tube wall section that is distributed with axial groove by the tubular type body of rod of casting is the olive-shaped reinforcement antiskid key of reinforcing rib, and antiskid key is by the injecting cement paste extension in wall-rock crack, thus conventional anchor is relied on olive-shaped reinforcement antiskid key mainly through 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 also reinforce the system of Rock And Soil, realize the right-about of anchor rod anchored mode and academic thought, that is construct olive-shaped reinforcement antiskid key-wall-rock crack slip casting-anchoring support NEW TYPE OF COMPOSITE slope reinforcement and support system, by group's anchor that many anchor poles are formed, realize being antiskid emphasis with slide plane and the comprehensive three-dimensional preventing land slide carrying out Rock And Soil reinforcing, transfer the self-stable ability of Rock And Soil better, improve the stability of Rock And Soil, the safety of engineering is strengthened greatly.
2, simple, the easy construction of structure of the present invention, with low cost, can speed up the work significantly.
