Abstract
The utility model discloses a kind of tension type anchor pole for reinforcing cut slope, including：Fastener（1）, bearing plate（2）, pedestal（3）, sleeve pipe（4）, pull bar（5）, anchorage mortar body（6）, steel plate（7）, screw（8）.The utility model is first by steel plate（7）With screw（8）Fastener to the anchoring section (L of anchor polea) reinforcing bar is divided at 3 and being fastened；It is free segment (the L of anchor pole at firstf) with the segmentation of anchoring section at；It is the midpoint of anchoring section reinforcing bar at second；It is the end terminal of anchoring section reinforcing bar at 3rd；The cohesive force of reinforcing bar and anchorage mortar body is improved at 3 to the anchoring of anchoring section reinforcing bar by this, the tensile capacity of anchor bar is given full play to；The utility model can improve the anchoring ability of anchor pole, can prevent again because of litter phenomenon caused by corrosion of reinforcing steel bar；It is not only simple in structure, and low cost, convenient construction.
Description
Technical field
The utility model is related to the field of road in civil engineering, particularly with regard to a kind of pulling force for reinforcing cut slope
Type anchor pole.
Background technology
The complex geologic body formed by very long geological epoch, the regular hour with it is certain under conditions of, in phase
To the poised state of stabilization, but because during expressway construction, Freeway of Mountain Range slope excavating destroys original life
State is balanced；The excessive deformation of geologic body will cause the generation of various geology disaster, such as landslide, avalanche, subsidence, right
Safe driving threatens；In the engineering geological mapping of dangerous rock slope, the deep rock for being frequently found rock mass is harder
Gu, do not influenceed by weathering, it is sufficient to support top layer rock that is unstable and there is certain unsafe condition；Adopt in this case
Rock bolting is carried out with anchor pole, is a kind of effective administering method.
For the tension type anchor pole generally used in China's engineering, the shearing stress distribution between anchoring section body and hole wall
Very uneven, there is serious shearing concentration phenomenon in anchoring section front end, so as to be moved after causing slurry drawing crack, effective anchoring section,
Ground shear resistance in the range of whole anchoring depth cannot be made full use of so that it cannot be met in bearing capacity, durability
And the requirement of engineering that the aspect such as antitypy has higher requirements.
The content of the invention
For problem above, the utility model discloses a kind of tension type anchor pole for reinforcing cut slope, using following skill
Art scheme：A kind of tension type anchor pole for reinforcing cut slope, by fastener, bearing plate, pedestal, sleeve pipe, pull bar, anchorage mortar
Body, steel plate, screw composition；Wherein described pull bar determines its position by sleeve pipe, and is consolidated by anchorage mortar body, and pull bar
The pulling force for being born passes to firm stratum by the cohesive force with anchorage mortar body；Described anchor pole is tight by fastener
Gu bearing plate fixes its position；A set of fastener that the utility model adds steel plate using screw first enters to anchoring section reinforcing bar
Row fastening, prevents because of slide bar phenomenon caused by the cohesive force deficiency between anchoring section reinforcing bar and anchorage mortar body；Next steel
Plate and screw outer layer carry out galvanized anticorrosive erosion treatment, prevent from being come off with anchorage mortar body because of reinforcement corrosion；It is final to realize increasing
The tensile capacity of strong anchor pole, and it is improved its service life.
A kind of tension type anchor pole of described reinforcing cut slope, it is characterized in that, described pull bar uses HRB400, diameter
25mm, the length that anchor pole squeezes into slopes determines according to the resistance to overturning of side slope and the rate of decay of side slope, and anchoring section steel
The length of muscle is doubled on the basis of valid bonding length.
A kind of tension type anchor pole of described reinforcing cut slope, it is characterized in that, described steel plate and screw are locked for one
It is fixedly mounted with and puts, and galvanized anticorrosive erosion treatment is carried out to it, the thickness of steel plate is 50mm.
A kind of tension type anchor pole of described reinforcing cut slope, it is characterized in that, described anchorage mortar body uses intensity
Grade is the strong concrete of C60, and wherein strength of cement grade uses 42.5 grades.
The beneficial effects of the utility model：Add a set of fastener of steel plate by simplest screw, to the anchor of anchor pole
Gu section reinforcing bar is reinforced, deficiency of the common tension type anchor pole in terms of bearing capacity is not only solved, and effectively prevent
Because slide bar phenomenon caused by anchoring section reinforcing bar is not enough with anchorage mortar body cohesive force；This method construction is simple, economic ring
Protect.
Brief description of the drawings
Fig. 1 is anchor pole skiagraph.
Fig. 2 is bolt anchorage cut slope earth-retaining figure.
Specific embodiment
The utility model textural association mode and implementation steps are described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, respectively the skiagraph of anchor pole and reinforce cut slope earth-retaining figure, including：Fastener

Bar（5）By sleeve pipe（4）It is located on the center line of hole to fix it；Described anchoring section reinforcing bar passes through steel plate（7）And screw（8）
The fastener of composition is fastened；Described anchorage mortar body（6）Anchor bar is anchored, and transmits pulling force to firm
Stratum；Described anchoring section reinforcing bar passes through steel plate（7）And screw（8）The fastener of composition is fastened again.
1st, it is first according to requirement to be drilled, armature boring should meet aperture, length and the inclination angle of design requirement, using suitable
Suitable boring method ensures precision, and the follow-up body of rod is inserted successfully is carried out with slip casting operation, in addition in boring procedure
In it should be noted that core pickup, core recovery is improved as far as possible, to analyze geological condition.
2nd, length cutting reinforcing bar as requested, calculates the anchoring depth and freedom length of reinforcing bar, and in leakage
Screw thread is processed into install screw in end and the starting point of anchoring section reinforcing bar, midpoint and end.
3 and then by steel plate（7）And screw（8）The corresponding position of anchoring section reinforcing bar is attached to, and steel plate is carried out zinc-plated
Anti-corrosion treatment, the size requirement of steel plate is consistent with the aperture of drilling, must not leave gap, and thickness is 50mm.
