The three-dimensional clamping type anchoring structure is formed into a whole by arranging 3 anchor rods in a crossed manner, and the clamping effect of surrounding rock and soil bodies can be fully exerted, so that the effect of improving the anchoring force is achieved.
Description
Technical Field
The utility model belongs to the technical field of the side slope is administered, concretely relates to be used for three-dimensional centre gripping type anchor structure of reinforced fiber composite of side slope.
Background
The anchoring structure is a common means for reinforcing the side slope, and has the advantages of clear stress mechanism, convenient construction, lower manufacturing cost and the like. The conventional anchor design mainly has the following two problems: (1) generally, a single anchor rod is taken as a unit and is arranged in parallel on a slope, the uplift resistance of each anchor rod is mainly provided by the side friction resistance of the anchoring section of the anchor rod, and under the condition of the geometric arrangement, the clamping effect of the rock mass on the structure is not fully utilized; (2) the traditional anchor rod is made of steel bars, and is easy to corrode and destroy in the environment with abundant underground water, complex geological conditions and severe weather conditions, so that the safety of an anchoring system is reduced, and even the anchor rod is broken and the whole structure is damaged due to failure. Therefore it is necessary to arrange the not enough of design and steel bar material to the parallel stock of tradition, develop the anchor rod structure that the pertinence is stronger, and the reinforcement effect of reinforcing stock solves the perishable problem of traditional steel bar stock.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a three-dimensional centre gripping type anchor structure of fibre reinforced composite for slope reinforcement is provided, this anchor structure can effectively utilize around "the grip effect" of the ground body, improves the bearing capacity of stock to adopt novel basalt fiber reinforced composite (BFRP) muscle, can effectively solve the corrosion problem of stock in the anchor soil body.
The utility model provides a technical scheme that its technical problem adopted is:
the three-dimensional clamping type anchoring structure for reinforcing the side slope comprises three anchor rods and an anchor rod base plate, wherein the anchor rods are made of basalt fiber reinforced composite materials, the anchor rod base plate is provided with three holes, and the three anchor rods penetrate through the three holes respectively to form a tripod structure.
The three holes are respectively distributed on the corners of the equilateral triangle.
The centers of the three anchor rods respectively penetrate through the holes in the anchor rod base plate at the positions with 30-degree included angles with the vertical line, and the top ends of the three anchor rods are gathered together.
The utility model discloses a technical effect who has mainly as follows:
(1) compared with the traditional parallel arrangement of anchor rods, the three-dimensional clamping type anchoring structure is formed into a whole by arranging the 3 anchor rods in a crossed manner, so that the clamping effect of surrounding rock and soil bodies can be fully exerted, and the effect of improving the anchoring force is achieved.
(2) The anchoring structure adopts basalt fiber reinforced composite (BFRP) ribs, effectively solves the corrosion problem of the traditional steel bar anchor rod, and has the advantages of high strength, light weight, tension retention rate equivalent to that of steel bars and the like.

Detailed Description
The specific technical solution of the present invention will be described with reference to the embodiments.
As shown in fig. 1, the fiber reinforced composite three-dimensional clamping type anchoring structure for slope reinforcement comprises three anchor rods 1 and an anchor rod backing plate 2, wherein the anchor rods 1 and the anchor rod backing plate 2 are made of basalt fiber reinforced composite, three holes are formed in the anchor rod backing plate 2, and the three anchor rods 1 penetrate through the three holes respectively to form a tripod structure.
As shown in fig. 2, the anchor bar 1 is
The basalt fiber reinforced composite material is made of basalt fiber reinforced composite materials, and the anchor rod base plate 2 is made of Q235 materials, the diameter of the anchor rod base plate is 280mm, and the thickness of the anchor rod base plate is 6 mm.
As shown in fig. 3, three of the holes are distributed in the corners of an equilateral triangle with a side length of 80 mm.
As shown in fig. 4, the centers of the three anchor bars 1 respectively penetrate through the holes on the anchor backing plate 2 at the positions with 30-degree included angles with the vertical line, and the top ends of the three anchor bars 1 are gathered together.
As shown in fig. 5, each anchoring structure is connected and fixed on the slope surface by using a frame beam, the section size of the frame beam is 0.3 × 0.4m, the anchoring structures are spaced by 3m, and the length of the anchor bar 1 can be respectively selected according to geological conditions.
The utility model provides a three-dimensional centre gripping type anchor structure execute and do the step mainly as follows:
(1) manufacturing a phi 22 Basalt Fiber Reinforced (BFRP) anchor bar rib 1, an anchor bar backing plate 2 and the like.
(2) The direction of the anchor rod is determined by the direction frame, mechanical drilling is used, and the inclination of the drilling tool is consistent with the inclination determined by the positioner during drilling.
(3) After the anchor rod number is checked to be consistent with the hole number, the installation of the anchor rod rib 1 is started, and the anchor rod base plate 2 is sleeved after the installation is finished.
(4) After all the anchor bars 1 are installed, C30 concrete is used for plugging the anchor heads, and the construction of the frame beam is started.
(5) The construction process of the frame beam is the same as that of the traditional parallel anchor rod, and the description is omitted below.
