Abstract
The utility model relates to a drilling type injecting anchor-bolt, composed of a rod body 1, a drill bit 2, a hole 3, and screws 4, wherein, one end of the rod body 1 is connected with the drill bit 2; the other end spout of the rod body 1 is matched with the screws 4 or screw threads of connection tools; the rod body 1 is canulate and is communicated with the hole 3 of the drill bit 2. The utility model integrates the functions of drilling, grouting, and anchoring, and ensures the anchoring effect under complicated stratigraphic condition. The utility model has the advantages of high reliability, efficiency, and convenience.
Description
The utility model is relevant with anchor pole, and is especially relevant with the grouted anchor bar of band drill bit.
Traditional engineering need be transferred to drilling rod after the hole breaks at first with the drilling rod punching of band drill bit with anchor pole again, and then with the anchoring materials such as steel pipe anchor pole injection cement of hollow anchor pole is fixed, and reaches the effect of reinforcing construction work.Need two cover instruments to be used alternatingly owing to creep into, use inconvenience, waste time and energy with slip casting, anchoring.Some stratum such as decomposed rock, detritus layer, back filled region, sand, clay, garden boulder bed etc. need add the sleeve pipe hole that prevents to collapse, and have more increased the weight of engineering cost.Traditional anchor pole is in the narrow scope construction inconvenience of folder, and anchor pole is also inconvenient with being connected of other construction equipment, and scope of application folder is narrow.
The purpose of this utility model provides a kind of simple in structure, and is easy to use, reliably of many uses, with low cost, with the anchor pole that creeps into, slip casting, anchoring function are integrated.
The body of rod 1 one ends of the present utility model and drill bit 2 are connected.The other end of the body of rod 1 is with nut 4 or be connected the facility threaded engagement.The body of rod 1 hollow and be communicated with the hole 3 of drill bit 2.
The body of rod 1 of the present utility model can be threaded with drill bit 2.The body of rod 1 stage casing is the garden slip pipe, no screw thread.
The body of rod 1 of the present utility model can have continuous wave ripple 4.
The utility model cover 7 that can be threaded cooperates with the body of rod 1.
The body of rod 1 of the present utility model can have continuous left-handed corrugated thread.The wave crest of screw thread be 12 or 12.70mm apart from ρ, the garden arc radius R 1=5.50mm of ripple, R2=6mm.R1, the garden arc of R2 is connected by common tangent.
The utility model collection drilling rod and anchor pole are one.The body of rod 1 is a hollow tube, and with the solid bar comparison of equal cross-sectional area, the hollow tube body of rod can bear bigger curved power, and shearing has bigger surperficial adhesion stress, can bear bigger load.
The utility model can high efficiency slip casting, and grouting pressure can be guaranteed, and anchor pole is as Grouting Pipe, carries out slip casting to the aperture from the bottom, the filling crack, fixed rock mass and soil layer, control underground water, easier than injecting method behind traditional first anchor, grouting pressure, anchoring quality is more guaranteed.
The utility model uses and fast to save time, and can save 25% workload, reduces engineering cost, even use and need not add that also sleeve pipe prevents the hole of collapsing at bad ground such as decomposed rock, detritus layer, back filled region, sand, clay, garden boulder bed.
The utility model is adapted at pressing from both sides narrow scope construction.Applied range can be used as anchor pole, soil nailing, stake and Grouting Pipe, can be applicable to tunnel, side slope, curb, engineerings such as foundation ditch.Have reliable, efficient, easy characteristics.
Following is accompanying drawing of the present utility model.
Fig. 1 is an overall construction drawing of the present utility model.
Fig. 2 is the corrugated thread structure chart.
Following is embodiment of the present utility model:
The body of rod 1 internal diameter 14-20mm, external diameter 25-38mm, wall thickness are 6.0-9.0mm.The body of rod 1 can adopt regular screw threads, also can adopt corrugated thread, and hand of spiral can be left-handed, but also dextrorotation.
The body of rod 1 two ends have screw thread 6, one ends to cooperate with drill bit 2, the other end can with adapter sleeve 7, nut 4, drilling tool and grouting pump interface cooperate, processing is not convenient to for the garden slip pipe has screw thread in the body of rod 1 stage casing, reduces manufacturing cost.The full-length of the body of rod 1 can be 2-6m, and maximum length can reach more than the 12m.
The body of rod 1 also can adopt continuous thread.
The wave crest of the corrugated thread of the body of rod 1 be 12 or 12.70mm apart from ρ, the garden arc radius R 1=5.50mm of ripple, R2=6mm, R1, R2 garden arc is connected by common tangent.
The body of rod 1 external diameter of the present utility model is 30mm, and the nominal aperture is 40mm, and the slip casting type is the M100 resin, and the yield strength of anchor system can reach 300KN, and ultimate strength can reach 337KN.Slip casting pressure can be 35MPa, and bond stress is 10-11.5MPa.
