Embodiment

[0052] as attached Figure 1-6 As shown, taking a certain earthen ruins as an example, the depth of the potential slip surface of the earthen ruins is between 100-600mm, and a small potential sliding body is formed on the earthen ruins; The reinforced anchoring system includes a fiber composite anchor rod 1 and a grouting body 6 .

[0053] The fiber composite anchor 1 is set in the anchor hole on the soil site to be reinforced, and the fiber composite anchor 1 is arranged in the soil site to be reinforced according to the preset spacing, length and angle; according to the soil mechanical properties of the soil site to be reinforced, the prepared For the grouting body material, use a grouting machine to pour the grouting body material into the anchor hole, and form the grouting body 6 in the gap between the fiber composite anchor rod 1 and the anchor hole.

[0054] The fiber composite anchor 1 includes geotechnical fiber filament 2, wrapping fiber 3, first stressed support 4 a...

Abstract

The invention discloses an anchoring system and method for earthen site reinforcement. The anchoring system comprises a fiber combined anchor rod and a grouting body, wherein the grouting body is poured into a gap between the fiber combined anchor rod and an anchor hole; the fiber combined anchor rod comprises a geotechnical fiber filament, wrapping fibers, a first stress bracket and a second bracket; the wrapping fibers are uniformly wound on the outer side of the geotechnical fiber filament; the first stress bracket is arranged at the rear end of the geotechnical fiber filament; the second bracket is arranged at the front end of the geotechnical fiber filament; and the two ends of the first stress bracket and the two ends of the second bracket are respectively fixed to the geotechnical fiber filament through the wrapping fibers in a clinging manner. According to the anchoring system and method, the geotechnical fiber filament can resist horizontal component force, the grouting body and the first stress bracket are used for resisting shearing and pressing together, and the second bracket plays a role in fixing and improving local anchoring performance, so that the opening diameter and the anchoring depth can be reduced, the local soil body shearing stress on the surface of an earthen site is reduced, and the probability of shearing, pressing and cracking of the surface of the earthen site in a reinforcement area is reduced.

Description

technical field [0001] The invention belongs to the technical field of structural reinforcement of earthen ruins in arid areas, and in particular relates to an anchoring system and method for reinforcing earthen ruins. Background technique [0002] Earth architectural sites are one of the important cultural heritages of human beings. There are many earth sites, but they are severely damaged, and most of them are in the stage of "rescue and reinforcement". Structural instability and damage caused by biological diseases and earthquakes is one of the important factors causing the large-scale extinction of ruins. Effectively and reasonably solving the problem of overall or local stability is a key link in its protection; Mechanical stability control technology is one of the most important measures to deal with the structural stability of the site. [0003] The existing anchorage measures for earthen ruins mainly use anchor rods such as bamboo, wood, steel bar or glass fiber, wh...
