Abstract
The utility model relates to a calabash-shaped anchor rod, which comprises a rod body and is characterized in that the rod body is a hollow anchor rod body with one end being a solid end; axial slots penetrating through a pipe wall are equidistantly formed on the pipe wall of the hollow anchor rod body close to the solid end along the peripheral direction; explosives are arranged in the pipe wall with the axial slots; and detonators are arranged in the explosives. The calabash-shaped anchor rod has a simple structure and low cost; the pulling resistance of the anchor rod is increased; the anchor rod is prevented from being subjected to rock soil anchoring damage, such as being pulled out of a slip casting body, so that the stability of rock soil is enhanced; the safety of anchoring tunnel, side slope, deep foundation pit, and the like, is greatly increased; and the calabash-shaped anchor rod is widely applied to the paving and anchoring of tunnel, side slope, deep foundation pit, and the like.
Description
Technical field
The utility model relates to the ground anchorage technology, relates in particular to cucurbit shape anchor pole.
Background technology
Ground anchorage is through being embedded in the anchor pole in the stratum; The stratum is locked together tightly; Rely on the interaction of anchor pole-injecting cement paste-hole wall ground muscle power, transfer and improve self intensity and self-stable ability of geotechnical body, to improve stress state; Guarantee the stable of outside geotechnical body, thereby guarantee the technology of engineering safety.The ground anchorage technology can be traced back to 19th century art in the application in engineering relevant with ground; Development along with its theoretical research and practical applications; The ground anchorage technology has been widely used in departments such as mine, water conservancy, water power, highway, railway, municipal administration, urban construction, geology, military project; As a kind of comparatively desirable support form, in underground construction, slope project, deep-foundation pit engineering etc. stable, play a significant role.
Ground anchorage not only receives the influence of formation lithology, Rock-soil Mass Structure, geological structure, hydrogeology etc., also possibly receive the effect of violent earthquake, and they all constitute a threat to the safety of ground anchorage.
Construction and run duration at ground anchorage; Anchor pole is extracted from injecting cement paste, anchor pole is extracted from anchor hole together with injecting cement paste is two kinds of ground anchorage mode of failure the most basic; They all can cause ground anchorage to lose efficacy; And bring hidden danger, thereby the uplift resistance that the restriction anchor pole can provide to engineering safety.Thereby; When the uplift resistance that provides when needs is big; The common anchor rod anchored needs that can not satisfy engineering become the bottleneck that restricts ground anchorage technical application and development, how to improve the Load Transfer mechanism of ground anchorage; Overcome the drawback of common friction-type anchoring, become the fundamental way that improves anti-pulling of anchor bar.
The utility model content
The utility model technical problem to be solved provides a kind of simple in structure, cucurbit shape anchor pole of improving anti-pulling of anchor bar.
For addressing the above problem, the described cucurbit shape of the utility model anchor pole comprises the body of rod, it is characterized in that: the said body of rod is that an end is the hollow bolt body of rod of solid termination; The said hollow bolt body of rod is near uniformly-spaced having the axial groove that penetrates said tube wall along circumferential direction on the tube wall of said solid termination; Have in the said tube wall of said axial groove and be provided with explosive; Be provided with primer detonator in the said explosive.
The utility model compared with prior art has the following advantages:
1, owing in the solid hollow bolt body of rod slotted line hollow tube wall in termination explosive is housed, the tube wall that the explosive charge effect has anchor pole an axial groove to around push into the cucurbit shape open, make the anchor pole bottom be able to enlarge; Simultaneously, filling and injecting slurry body in the hollow bolt body of rod and between anchor pole tube wall and the drill hole wall geotechnical body; Through this anchor rod anchored; Optimized and improved the Load Transfer mechanism of geotechnical body anchoring significantly; Make common friction-type anchoring convert friction-pressure-type anchoring to; Both prevented that anchor pole from extracting from anchor hole together with injecting cement paste---be that anchor pole destroys together with the contact interface of injecting cement paste edge with geotechnical body, the ground anchorage destruction that prevents that also anchor pole from extracting simultaneously from injecting cement paste and wait, thus improved the uplift resistance of anchor pole; Strengthened the stability of geotechnical body, the safety of anchoring tunnel, side slope, deep foundation ditch etc. is strengthened greatly.
2, simple in structure, with low cost, the easy construction of the utility model can be widely used in the anchoring of tunnel, side slope, deep foundation ditch etc.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Fig. 2 uniformly-spaced has the anchor pole bottom and the powder charge sketch map of axial groove along circumferential direction for the utility model.
Fig. 3 uniformly-spaced has the anchor pole bottom and the powder charge shaft section figure of axial groove along circumferential direction for the utility model.
Fig. 4 is the shaft section sketch map after the slip casting anchoring of the utility model bottom.
Among the figure: the solid termination of 1-hollow bolt body of rod 2-tube wall 3-axial groove 4-explosive 5-cucurbit knee 6-.
The specific embodiment
Shown in Fig. 1～4, cucurbit shape anchor pole comprises the body of rod.This body of rod is that an end is the hollow bolt body of rod 1 of solid termination 6.The hollow bolt body of rod 1 is near uniformly-spaced having the axial groove 3 that penetrates tube wall 2 along circumferential direction on the tube wall 2 of solid termination 6; Have in the tube wall 2 of axial groove 3 and be provided with explosive 4; Be provided with primer detonator in the explosive 4.
During use, hole to the weak rocks soil body by designing requirement (1); (2), form cavity at the bottom of making the boring hole to implementing reaming at the bottom of the boring hole; (3) termination is solid hollow shop club shaft 1 inserts in the boring; (4) detonating charge 4; Explosive 4 blasts produce strong effect to the tube wall 2 that the solid hollow bolt body of rod 1 in termination has axial groove 3; Make tube wall 2 to pushing into cucurbit knee 5 shapes open all around, cause the bottom of the solid hollow bolt body of rod 1 in termination to be able to enlarge, thereby produce cucurbit shape anchor pole; (5) to boring slip casting, make cucurbit shape anchor pole be able to anchoring and get final product.
Claims (1)
1. cucurbit shape anchor pole comprises the body of rod, it is characterized in that: the said body of rod is that an end is the hollow bolt body of rod (1) of solid termination (6); The said hollow bolt body of rod (1) is gone up along circumferential direction near the tube wall (2) of said solid termination (6) and is uniformly-spaced had the axial groove (3) that penetrates said tube wall (2); Have in the said tube wall (2) of said axial groove (3) and be provided with explosive (4); Said explosive is provided with primer detonator in (4).
