Novel geogrid with ground anchors attached

Abstract

The invention discloses a novel geogrid with ground anchors attached. The novel geogrid with the ground anchors attached comprises a geogrid body. The geogrid body comprises a plurality of independent cells composed of transverse ribs and longitudinal ribs in an intersected mode. At least one face of the geogrid body is fixedly provided with the ground anchors. Each ground anchor is fixedly arranged on one transverse rib and / or one longitudinal rib or on the intersecting portion of one transverse rib and one longitudinal rib. The novel geogrid with the ground anchors attached is simple in structure, convenient to manufacture and capable of increasing the binding force of the geogrid and a soil body, effectively controlling relative sliding of the geogrid and the soil body, greatly strengthening the application effect of the geogrid, and meanwhile reducing the use amount of the geogrid.

Description

technical field [0001] The invention relates to a new type of geogrid, especially a kind of auxiliary structure that can be widely used in the fields of soft soil foundation reinforcement, retaining wall and road surface cracking engineering of highways, railways, bridge abutments, approach roads, docks, dams and other projects. A new type of geogrid for anchors. Background technique [0002] At present, in the construction of various dams and roadbed reinforcement, slope protection, cave wall reinforcement, large airports, parking lots, wharf yards and other permanent bearing projects, in order to make the post-construction effect more obvious and prevent disasters, Geogrids are often used. Geogrid has many advantages. It is convenient for construction, saves time and effort, can shorten the construction period and reduce maintenance costs. In highway engineering, it can increase the bearing capacity of the subgrade foundation and prolong the service life of the subgrade ...

AI Technical Summary

Problems solved by technology

During the laying process, poor contact with the soil may easily cause relative slippage between the geogrid and the soil, and cracks and gaps are likely to occur on the contact surface, resulting in unsatisfactory reinforcement effects.

Especially in the process of widening the road, the poor contact between the geogrid and the old and new subgrades leads to a decrease in the bonding force, which makes it impossible to effectively control the differential settlement of the old and new subgrades. The uneven settlement of the subgrade will lead to a series of problems such as cracking of the road surface

In some large-scale projects, due to the huge amount of engineering, the extensive use of geogrid will cause the loss of economic benefits

The limitations of the geogrid material itself not only reduce the performance and effect of the geogrid, but also cause a waste of resources and bury the safety hazards of the whole project.
