Geogrid with anchoring nails and construction method thereof

Abstract

The invention discloses a geogrid with anchoring nails and a construction method thereof. The geogrid comprises a geogrid body, a plurality of anchoring nail heads and anchoring nail bodies, the geogrid body is composed of a longitudinal main grid bar, an oblique grid bar and a longitudinal auxiliary grid bar, and the multiple anchoring nail heads are connected to the longitudinal main grid bar ofthe geogrid body at equal intervals; the anchoring nail bodies are connected in embedded blocks at the bottom of the anchoring nail heads, anchoring tip cones are arranged at the bottom ends of the anchoring nail bodies, and expansion fins are arranged on the side walls of the anchoring tip cones; and a plurality of expansion cone rings are arranged on the side walls of the anchoring nail bodiesat equal intervals, and expansion gear rods are connected to the anchoring nail bodies at the rear sides of the expansion cone rings. The structural strength and the tensile strength of the geogrid body are enhanced, anchoring stability of the anchoring nail bodies is improved, the contact surface between the geogrid body and the soil body is strengthened, the connection strength is enhanced, connection between the geogrid body and the soil body is realized, the bearing capacity and stability of the soil body are improved, and paving for the geogrid body is realized.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a geogrid with anchor nails and a construction method thereof. Background technique [0002] Geogrids have been widely used since the middle of the 20th century, and entered my country in the 1980s, developing rapidly. At present, geogrids have been widely used in water conservancy, railways, highways, ports and construction projects, solving many civil engineering projects. The technical problems in the process have achieved good social and economic benefits. [0003] Geogrid fills the road matrix and plays the role of reinforcing ribs. The existing geogrid uses some composite materials, which can play the role of corrosion resistance and water resistance. However, when the geogrid is generally a flat structure, it will The contact surface between filling materials is small, and the internal materials are easy to delaminate and fall off. When geogrids are used to tighten soil s...

[0003] Geogrid fills the road matrix and plays the role of reinforcing ribs. The existing geogrid uses some composite materials, which can play the role of corrosion resistance and water resistance. However, when the geogrid is generally a flat structure, it will The contact surface between filling materials is small, and the internal materials are easy to delaminate and fall off

When geogrid is used to tighten soil subgrade engineering, foundation treatment and fill slope protection engineers, due to poor anchorage performance and low tensile strength of geogrid, soil stability is poor
