Problems solved by technology

[0003] The traditional anchor rods are easy to rust, the long-term performance of the system is poor, and the mechanical bite force is small. For areas with poor engineering geological conditions and rich groundwater, the traditional anchor rods have a high risk of structural failure due to the corrosion resistance of the material, and the later stage of the project Stable operation and maintenance costs are high

Embodiment 1

[0040] Such as Figure 1~3 As shown, this embodiment provides a fishbone-shaped basalt fiber anchoring system, including a fishbone-shaped basalt fiber anchor 1, and the top of the fishbone-shaped basalt fiber anchor 1 is pierced with an anchor 3; the fishbone-shaped basalt fiber anchor 1 is provided with a herringbone-shaped protruding structure, and the herringbone-shaped protruding structure includes a plurality of centering brackets 2, and the centering bracket 2 includes a circular base 21, which is used to be sleeved on the fishbone-shaped On the basalt fiber bolt 1, a plurality of branch structures are arranged on the outer edge of the ring base 21 in the circumferential direction, one end of the branch structure is fixed on the ring base 21, and the other end of the branch structure is inclined upward.

[0041] Such as Figure 1~3 As shown, the branch structure is inclined rods 22, and four inclined rods 22 are evenly arranged on the outer edge of the circular base 21...

Embodiment 2

[0051] Such as Figure 4 As shown, this embodiment provides a fishbone-shaped basalt fiber anchoring system. On the centering bracket 2, one end of the branch structure is fixed on the outer edge of the circular base 21, and the other end of the branch structure is set as a bifurcated structure 23 to form antlers. 4 branch structures are evenly arranged on the outer edge of the ring base 21 in the circumferential direction, and the angle between the bifurcation structure 23 and the axial direction of the fishbone basalt fiber bolt 1 can be adjusted according to the difference in the use object. The adjusted, antler-like branch structure is conducive to strengthening the connection between the anchor rod and the anchor grout, and greatly increasing the mechanical bite force of the anchor rod.

[0052] In this embodiment, only the structure of the centering support 2 is different from that of the centering support 2 in Embodiment 1. The connection and fixing method, arrangement ...

Embodiment 3

[0054] This embodiment provides an anchoring method based on the above fishbone basalt fiber anchoring system, comprising the following steps:

[0055] Step 1: Before the construction of fishbone basalt fiber bolts, connect with the hydrogeological information and survey coordinate information given by the design unit according to the design documents, and combine the existing construction conditions for construction arrangements, organizational flow, and safety. The protection and emergency treatment plan will be reviewed in detail, and the site will be cleaned up to facilitate construction and minimize the probability of safety accidents;

[0056] Step 2: Determine the location of the anchor hole according to the requirements of the design drawings, use the drilling machine to drill the hole, and recheck the size of the formed hole. After the size of the hole is rechecked, use the hole cleaning tool to clean the soil residue in the hole. The anchor hole is formed after clean...

Abstract

The invention discloses an anchoring system of a fishbone-shaped basalt fiber. The system comprises a fishbone-shaped basalt fiber anchor rod, an anchorage device is arranged at the top end of the fishbone-shaped basalt fiber anchor rod in a penetrating and inserting mode, and a fishbone-shaped bulge structure sleeves the basalt fiber anchor rod; and the fishbone-shaped bulge structure comprises aplurality of centering supports, each centering support comprises a circular ring base, a plurality of branch structures are arranged on the outer edges of the circular ring bases in the circumferential direction, one ends of the branch structures are fixed on the circular ring bases, and the other ends of the branch structures are obliquely arranged upwards. The fishbone-shaped basalt fiber anchor rod is scientific and reasonable in structure and easy to install, the operation is convenient, the property of light weight and high strength of the basalt fiber material is utilized, the materialbasis is provided for improving the corrosion resistance of the anchor rod, and the operation quality long-term performance of the anchor rod are improved, so that the problem that a traditional anchor rod is prone to rust is fundamentally solved; and meanwhile, the invention provides an anchoring method capable of improving bonding strength of the anchor rod, the operation is convenient, the bonding strength of the anchor rod can be improved, so that the construction quality of the anchoring system is further improved.

Description

technical field [0001] The invention relates to the technical field of anchoring, in particular to a fishbone basalt fiber anchoring system and an anchoring method thereof. Background technique [0002] The bolt technology has been favored by the engineering community for its outstanding advantages such as simple structure, safe construction, small disturbance to the slope, little impact on nearby buildings, and saving engineering materials. It has been developed rapidly and widely used in recent years, and has almost touched Every corner of the civil engineering field, including slopes, foundation pits, mines, tunnels, underground engineering, dams, waterways, reservoirs, airports, and anti-tilting, anti-floating structures and other engineering constructions. With the vigorous construction of infrastructure in our country, especially the increase in the construction of transportation, energy, water conservancy and urban infrastructure, anchoring technology has shown a very...
