Technical Field
The invention relates to a steel-plastic geogrid net connecting device applied to the field of soft foundation reinforcement engineering, which is particularly suitable for reinforcement areas with complex construction conditions and large quantity of grid nets to be spliced.
Background
When soft foundations such as roadbeds, dykes and dams and side slopes are treated, geogrids are often used as reinforcement materials to improve the performance of soil and reduce differential settlement of the roadbeds in order to increase the bearing capacity of soil layers and prevent disasters. In some construction conditions comparatively complicated sections, can inevitably tailor geogrid and overlap joint, at present, overlap joint between the grid net piece adopts the ligature to connect more, and two adjacent grid nets are in the same place through the ligature area, if overlap joint position receives great load, such overlap joint mode very easily leads to the grid net to receive concentrated stress, when concentrated stress is too high, grid area junction position can be pulled out, causes the phenomenon of drawing wire to make the grid net produce certain displacement, seriously influence geogrid's reinforcement performance, bring certain potential safety hazard for the engineering.
Therefore, a lap joint device which can ensure the lap joint effect of the steel-plastic geogrid net and avoid the occurrence of larger concentrated stress is needed, so that the lap joint part of the geogrid net can keep better continuity and integrity when receiving larger load, and the occurrence of overlarge concentrated load is avoided, thereby ensuring the quality and safety of engineering.
