Cabin-type anchoring device and construction method using fiber-reinforced composite materials

Abstract

The invention relates to a cabin type anchor device made of a fiber reinforced composite material and a construction method. The cabin type anchor device comprises a structure anchor assembly, a binding sleeve and an expandable cabin; and the binding sleeve is internally provided with at least one rib, plate or stranded wire made of the fiber reinforced composite material. The cabin type anchor device made of the fiber reinforced composite material is adopted, through combination of the rib, plate or stranded wire made of the high-performance fiber reinforced composite material and the expandable cabin, the bearing force and the durability of a soil body anchor rod are greatly improved; and through the binding force transmission manner of combining the rib, plate or stranded wire made of the high-performance fiber reinforced composite material and the binding sleeve or a binding casing pipe, the technical problem that reliable anchoring of the high-performance fiber reinforced composite material is difficult to achieve due to the low transverse shearing strength is solved. By means of the new technology, the self carrying capacity of a soil body can be sufficiently transferred under the complicated geological condition, so that the bearing and antiseptic properties of rock-soil anti-lifting components are improved, and industrialized production and light-weight transportation and installation are facilitated.

Description

technical field [0001] The invention relates to a rock-soil anchorage that is applied in the field of civil engineering and has anti-corrosion and high load-bearing requirements in rock-soil anchorage projects such as building (structure) structure anti-floating and anti-overturning, foundation pit support and slope protection, etc. Components and their implementation methods. Background technique [0002] The rock-soil anchoring technology shows the advantages of safety, reliability and low cost by fully mobilizing the resistance of the rock-soil mass itself. In the past 20 years, many anchor structures have been invented and created in the field of geotechnical engineering to improve the bearing capacity and durability of anchor bolts. However, the load-bearing capacity of rock-soil bolts is still limited by the strength of anchor reinforcement materials, and traditional steel strands, steel bars and other materials can no longer meet the urgent needs of new-type rock-soi...

AI Technical Summary

Problems solved by technology

However, the bearing capacity of rock-soil bolts is still limited by the strength of anchor reinforcement materials, and traditional steel strands, steel bars and other materials can no longer meet the urgent needs of new rock-soil bolts for high bearing capacity.

[0003] On the other hand, domestic and foreign geotechnical engineering circles have found in engineering practice that steel anchors have technical bottlenecks such as corrosion and insufficient durability. These technical defects have seriously affected the service life of geotechnical anchors and reduced the safety of anchorage structures.

Although engineers and technicians have tried to adopt anti-corrosion measures such as anchor centering brackets, grout anti-corrosion agents, or galvanized steel rod surfaces, due to the difficulty in controlling the construction quality of concealed projects and the corrosiveness of rock and soil formations and groundwater, the corrosion of steel anchors Anti-corrosion technical problems have not been solved so far

In addition, due to the heavy weight of steel in engineering applications, steel anchors bring difficulties to transportation and installation, and increase the cost of geotechnical anchoring construction
