Description

One is revolved and is expanded integral type anchor pole
Technical field
The utility model relates to a kind of soil bolt, and specifically one is revolved and expanded integral type anchor pole, belongs to technical field of civil engineering.
Background technology
Soil bolt is called for short soil anchor bolt, be the soil layer internal drilling of not excavating at deep foundation Tu Bi, after reaching certain depth, in hole, put into the materials such as reinforcing bar, steel pipe, steel tendon, steel strand, pour into mud or chemical grout, make itself and soil layer be combined into the strong anchor pole of tension (pulling out) power.Anchor pole end and lagging pile connect, and prevent Tu Bi from caving in or come down.Support is not established, so execution conditions are better in cheating.
Current existing soil bolt reinforcing technique general step is: first hole and put into anchor pole afterwards, then to the inner slip casting of anchor hole.This method by boring with establish muscle to separate to implement, complex procedures, and at soft layer and the higher soil layer of moisture content, can fall damage be there is in the hole first formed, be not easy to the placement of dowel, and after general soil bolt slurry solidification, cross section is comparatively level and smooth, makes the frictional resistance of the bond stress of anchor pole and anchoring body, anchoring body and hole wall less, and the situation that anchor pole comes off easily occurs.
Summary of the invention
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of easy construction and not easily revolving of slip expands integral type anchor pole.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
One is revolved and is expanded integral type anchor pole, comprise a steel pipe, one end of steel pipe arranges taper bit, the other end arranges rig, steel duct is provided with guide rod, steel pipe tube wall is provided with cutting steel disc, strut is connected with between guide rod and cutting steel disc, guide rod drives strut to move back and forth in steel pipe, thus drives opening and shrinking of cutting steel disc, cuts on steel disc and is provided with grouting port, when cutting steel disc and being in open configuration, grouting port stretches out steel pipe walls outside, and when cutting steel disc and being in contraction state, grouting port is positioned at steel pipe walls inside.
Described cutting steel disc forms barb in anchoring body, avoids anchor pole and extracts from anchoring body.
Described taper bit welds with steel pipe integral.
Described cutting steel disc is evenly arranged along steel pipe body length, cuts steel disc on steel pipe cross section in crossing distribution.
Described guide rod and strut hinged, strut with cut steel disc hinged, by the propelling of rig to guide rod make cut steel disc open.
Described cutting steel disc and grouting port weld together.
Above-mentioned taper bit is connected with steel-pipe welding, makes steel pipe both directly can be driven into soil layer at Soft Soil Layer, also can in precession in comparatively hardpan.
Outer wall of steel pipe is provided with cutting steel disc every a segment distance, cuts steel disc on steel pipe cross section in crossing distribution.Cut steel disc and strut hinged, by the guide rod of rig promotion steel duct, cutting steel disc is opened by strut.Reaming first done by cutting steel disc in construction, after slurries inject anchor hole, form barb-like reinforcement structure.Cut below steel disc and have grouting port, the rear of reaming can be rotated at cutting steel disc and inject slurries in anchor hole.
Compared with prior art, the beneficial effects of the utility model are:
1. the boring of anchor pole and bar planting two steps are integrated by the utility model, reduce the working procedure of bolt anchorage, substantially increase efficiency of construction.
2. owing to being provided with cutting steel disc, make anchor hole be able to further expansion, slurries form irregular anchoring body after filling, and substantially increase the bond stress of anchor pole and anchoring body, the frictional resistance of anchoring body and hole wall, makes the structural strength of anchor pole and stability obtain enhancing like this.
3., after cutting steel disc solidifies in slurries, in anchoring body, form barb, avoid anchor pole and extract from anchoring body.
4. grouting port is below cutting steel disc, and grouting port is hidden in steel duct with during precession being driven into, and vertical with cutting direction when revolving expansion, the soil body is difficult to enter to be avoided blocking.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 shows the overall structure of revolving and expanding integral type anchor pole;
Fig. 2 shows and cuts the structural representation that steel disc opens reaming formation anchoring body;
Fig. 3 shows the structure of cutting steel disc;
In figure: 1-rig, 2-steel pipe, 3-nut, 4-pallet, 5-guide rod, 6-strut, 7-cuts steel disc, 8-taper bit, 9-grouting port, 10-anchoring body.
Detailed description of the invention
For making the purpose of this utility model and technical scheme clearly, below in conjunction with the utility model embodiment, the technical solution of the utility model is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
