Abstract
The utility model provides a novel squeeze into formula steel pipe soil nail is including shape reinforcing bar, steel pipe, injected hole, angle steel barb and the pointed cone form pin fin of preapring for an unfavorable turn of events, preapre for an unfavorable turn of events the shape reinforcing bar be the spiral, screw thread welded steel is in the one end of steel pipe, the welding of pointed cone form pin fin is at the other end of steel pipe, be provided with the injected hole on the steel pipe, it has the angle steel barb to weld at the injected hole and near one side of pointed cone form pin fin, the orthographic projection of angle steel barb covers the injected hole completely. The utility model has the advantages of the front -end design that squeezes into formula steel pipe soil nail is the pointed cone form resistance that the pin fin is effectual when reducing to squeeze into, strike the butt welding at the steel pipe and connect threaded reinforcing bar, can effectively avoid the steel pipe to warp, through at injected hole outside welding angle steel barb, effectually improved the soil nail withdrawal resistance and avoided the injected hole to be blockked up.
Description
Technical field
The utility model relates to building field, particularly relates to a kind of novel driving into type steel tube for soil-nail.
Background technology
The application of soil nailed wall retaining structure in base pit engineering widely, it by placing the soil nailing body of certain length and distribution density in the soil body, and steel concrete panel is set outside the soil body, so effectively improve the integral rigidity of the soil body, tensile strength and shear strength, whole slope stability can be improved significantly.
Soil nailing generally adopts the reinforcing bar soil nailing of luoyang spade pore-forming, but loose or slightly close sand, the slightly close silt of commute collapse hole, bankets, or the weak soil of easily necking down should adopt driving into type steel tube for soil-nail.But there is certain defect in existing driving into type steel tube for soil-nail, be mainly reflected in application process: driving into type steel tube for soil-nail squeezed into slightly close sand, slightly close silt, banket in process,
Under large impact power, the end of steel tube for soil-nail is easily out of shape; Next is the loose driving into type steel tube for soil-nail being applied to easy collapse hole, usually on driving into type steel tube for soil-nail, is provided with injected hole, but existing injected hole operator guards is unreasonable, causing driving into type steel tube for soil-nail easily to block when squeezing into the soil body, affecting slip casting effect.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of novel driving into type steel tube for soil-nail, and this driving into type steel tube for soil-nail efficiently solves mutability, the susceptible to plugging technical problem that conventional art exists.
A kind of novel driving into type steel tube for soil-nail comprises anti-deformation reinforcing bar, steel pipe, injected hole, angle steel hangnail and cone-shaped ailhead;
Described anti-deformation reinforcing bar is indented bars, and described indented bars is welded on one end of steel pipe, and described cone-shaped nail head bond is connected on the other end of steel pipe;
Described steel pipe is provided with injected hole, and be welded with angle steel hangnail at injected hole and near the side of cone-shaped ailhead, the orthography of described angle steel hangnail covers injected hole completely.
Further, the position that described injected hole is arranged be steel pipe length 1/2 to 1/3 between.
The beneficial effect of technical scheme described in the utility model is: the Front-end Design of driving into type steel tube for soil-nail is the resistance that cone-shaped ailhead effectively reduces when squeezing into; Hit end at steel pipe and be welded with indented bars, effectively can avoid pipe deformation; By welding angle steel hangnail outside injected hole, effectively raise pulling capacity of soil nail power and to avoid injected hole blocked.
Accompanying drawing explanation
Fig. 1 one described in the utility model novel driving into type steel tube for soil-nail overall structure schematic diagram;
In figure: 1 anti-deformation reinforcing bar, 2 injected holes, 3 angle steel hangnails, 4 steel pipes, 5 cone-shaped ailheads.
Detailed description of the invention
As shown in Figure 1, one described in the utility model novel driving into type steel tube for soil-nail comprises anti-deformation reinforcing bar 1, steel pipe 4, injected hole 3, angle steel hangnail 3 and cone-shaped ailhead 5; Described anti-deformation reinforcing bar 1 is indented bars, and described indented bars is welded on one end of steel pipe 4, and described cone-shaped ailhead 5 is welded on the other end of steel pipe 4; Described steel pipe 4 is provided with injected hole 2, and be welded with angle steel hangnail 3 at injected hole 2 and near the side of cone-shaped ailhead 5, the orthography of described angle steel hangnail 3 covers injected hole 2 completely.
During construction, first had a down dip by steel tube for soil-nail and impact in loose, soft layer, then use neat slurry slip casting, cement paste penetrates into the soil body around steel tube for soil-nail through steel pipe, injected hole, around steel pipe, form the anchoring body that intensity is higher, thus play anchorage effect.
A kind of novel driving into type steel tube for soil-nail described in the utility model solves the problem of loose, the easy collapse hole of soft layer nail Construction, easily necking down; Injected hole is protected, injected hole blocking when avoiding entering the soil body simultaneously; By add prevent impact distortion add competent structure, avoid the destruction of steel tube for soil-nail afterbody; In addition, it is simple that novel driving into type steel tube for soil-nail described in the utility model has making, with low cost, easy construction, supporting certain features.
Claims (2)
