Abstract
The utility model discloses a hollow self-propelled anchor rod, comprising a drill rib. The drill rib is in a herringbone structure; a thrust drilling rod is fixedly connected with the drill rib and is hollow; grouting holes are uniformly formed on the lateral wall of the hollow drilling rod; an anchor cable fixing board is mounted at the lower end of the hollow drilling rod; a plurality of holes for hanging a steel cable in a penetrating manner are formed on the anchor cable fixing board; and the anchor cable fixing board is connected with the steel cable through the holes for hanging the steel cable in the penetrating manner. The hollow self-propelled anchor rod provided by the utility model can finish the processes of self-drilling, grouting, self-guniting and one-step installation of the anchor rod and the anchor cable and has the advantages of simple and smart structure and convenience in use.
Description
Technical field
The utility model relates to a kind of self-advancing type soil anchor composite set, and it can accomplish boring slip casting synchronously and anchor shaft anchor cable is installed.
Background technology
Grouting rock bolt is being safeguarded extensive use aspect the stability of slope.The speed of anchor bolt construction quality and anchor bolt construction is the focus that people are concerned about always, and the anchoring effect of anchor pole has important function to geotechnical engineering stability.
Construction or be easy to generate the hole of collapsing during anchor cable in the soft broken geotechnical body.The main mode that solves the hole of collapsing at present is to adopt mud off or sleeve pipe follow-up bore process.These two kinds of technologies all have certain defective: sleeve pipe follow-up difficulty of construction is big, cost is high.The later stage anchor shaft anchor cable of mud off construction is installed complicated, also need withdraw from Grouting Pipe gradually.Moreover mud off reduces the side friction of soil layer, reduces the uplift resistance of anchor pole greatly.
Simultaneously, the grouting rock bolt anchor cable that uses at present mainly contains following deficiency in construction:
1, need at first to hole, put into anchor pole or anchor cable then, slip casting again needs 3 procedures, and operation is comparatively complicated.
2, during holing with slurry wall protection, because the effect of mud reduces anchoring effect.
When 3, advancing with pipe bit, speed of application is slow, and cost is high.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, and a kind of hollow self-feeding anchor pile is provided, and it can be realized from brill, slip casting, whitewashing and the completion of anchor shaft anchor cable once mounting certainly.Simple and ingenious structure, easy to use.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model provides a kind of hollow self-feeding anchor pile, comprises the drill bit fin, and said drill bit fin is " people " font structure; Said drill bit fin is fixedly connected a thrust drilling rod; Said thrust drilling rod is a hollow drill, evenly offers grout hole on the sidewall of hollow drill, and the lower end of said hollow drill is equipped with an anchor cable fixed head; Said anchor cable fixed head is provided with a plurality of holes that hang steel cable of wearing, and is connected with steel cable through wearing the hole that hangs steel cable.
The hole that hangs steel cable of wearing on the said anchor cable fixed head is evenly arranged.
Double as drilling rod of the utility model hollow self-feeding anchor pile own and Grouting Pipe.Can make dust blowing tube before the slip casting, both get rid of the dust that rock drilling forms, slurries spray from drill bit through hollow bolt during slip casting, and boring and crack, stratum around the anchor pole of filling a vacancy make anchor pole and soil property on every side be frozen into one, and formation steel pipe concrete column plays the effect of reinforcing.Thereby the utility model can be realized from brill, slip casting, whitewashing and the completion of anchor shaft anchor cable once mounting certainly.Simple and ingenious structure, easy to use.
The utility model is mainly used in the construction of fault belt excavation supporting; Under complex geological condition, replace the ordinary mortar anchor pole; Overcome ordinary mortar anchor pole such as the hole of collapsing, can't inserted link, a difficult problem such as slip casting is not full, brought into play the effect of bolt support, improved the supporting capacity of country rock; Guarantee the monolithic stability of country rock, had using value preferably.
The characteristics of the utility model have:
1, the self-advancing type hollow grouting anchor adopts good thick-walled seamless steel pipes material, perfect the thread surface forming technology and the superior accessory of doing manual work efficiently, has really realized the unification of functions such as automatic anchor pole boring, slip casting, anchoring.
2, the strong drill bit of penetration power is arranged before the self-advancing type hollow grouting anchor, under the effect of general rock drilling machinery, can penetrate each rocks easily.
3, have continuous international standard corrugated thread, can be used as drilling rod and cooperate the drill bit completion to hole into anchor hole.
4, the anchor bar body of drilling rod need not to extract, and its hollow can be used as the slip casting passage, carries out slip casting from the inside to the outside.
5, dynamical stop grouting plug makes slip casting can keep stronger grouting pressure; Filling space fully; Fixing fragmented rock body, high-intensity backing plate, nut can be delivered to deep-level country rock stress on the perisporium country rock equably, reach the purpose of country rock and anchor pole supporting each other.
6, make when it is constructed under all kinds of wall rock conditions owing to the Trinitarian function of anchor pole, do not need special skills such as sleeve pipe retaining wall, preparatory slip casting also can form anchor hole and guarantee anchoring and slip casting effect.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model provides a kind of hollow self-feeding anchor pile, comprises drill bit fin 1; Said drill bit fin is " people " font structure, and said drill bit fin is fixedly connected a thrust drilling rod 2, and said thrust drilling rod is a hollow drill; Evenly offer grout hole 3 on the sidewall of hollow drill; The lower end of said hollow drill is equipped with an anchor cable fixed head 4, and said anchor cable fixed head is provided with a plurality of holes that hang steel cable of wearing, and is connected with steel cable 5 through wearing the hole that hangs steel cable.
The hole that hangs steel cable of wearing on the said anchor cable fixed head is evenly arranged.
Double as drilling rod of the utility model hollow self-feeding anchor pile own and Grouting Pipe.Can make dust blowing tube before the slip casting, both get rid of the dust that rock drilling forms, slurries spray from drill bit through hollow bolt during slip casting, and boring and crack, stratum around the anchor pole of filling a vacancy make anchor pole and soil property on every side be frozen into one, and formation steel pipe concrete column plays the effect of reinforcing.Thereby the utility model can be realized from brill, slip casting, whitewashing and the completion of anchor shaft anchor cable once mounting certainly.Simple and ingenious structure, easy to use.
The utility model is mainly used in the construction of fault belt excavation supporting; Under complex geological condition, replace the ordinary mortar anchor pole; Overcome ordinary mortar anchor pole such as the hole of collapsing, can't inserted link, a difficult problem such as slip casting is not full, brought into play the effect of bolt support, improved the supporting capacity of country rock; Guarantee the monolithic stability of country rock, had using value preferably.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the utility model.
