Detailed Description
Example 1
Referring to fig. 1-3, in the present embodiment, the geogrid for overlapping new and old roadbed includes a positioning hole 12 formed at a node 11 of the geogrid 10, a positioning rod 20 is inserted into the positioning hole 12, a pressing plate 21 pressed against the geogrid 10 is disposed at the top of the positioning rod 20, a tapered limiting plate 22 is disposed at the periphery of the positioning rod 20, and the limiting plate 22 is fastened to a limiting table 13 formed in the positioning hole 12.
According to the embodiment, the existing geogrid is optimized and improved, the limiting plate 22 is additionally arranged on the positioning rod 20, so that when the positioning rod 20 is extruded by external force, the limiting plate 22 can move into the positioning hole 12 along with the positioning rod 20 and is buckled with the limiting table 13, the stability of connection between the positioning rod 20 and the geogrid 10 is improved, and the geogrid has the advantage of simplicity and convenience in operation.
It should be noted that, the positioning rod 20, the pressing plate 21 and the limiting plate 22 in this embodiment together form a fixing mechanism for fixing the geogrid 10, the positioning holes 12 are integrally formed at each node 11 of the geogrid 10, and the fixing mechanism can be arranged inside the corresponding positioning hole 12 according to needs during actual use, and the fixing structure does not need to be arranged in each positioning hole 12, so long as the position selection of the fixing structure is ensured, and an effective fixing effect can be achieved on the geogrid 10.
When in actual use, the lower extreme of locating lever 20 is in driving into ground after passing locating hole 12, and clamp plate 21 sets up in the upper end of locating lever 20 to the crimping is in the top of node 11, realizes compressing tightly the location to geogrid 10, simultaneously, limiting plate 22 is following locating lever 20 synchronization behind pressing in locating hole 12, can realize with spacing 13 lock joint, utilizes clamp plate 21 and limiting plate 22's work restriction effect, can avoid locating lever 20 to break away from in locating hole 12, has guaranteed the stability that locating lever 20 and geogrid 10 are connected.
When the positioning rod 20 is mounted in the positioning hole 12, the positioning rod 20 is pressed by force, for example, the positioning rod 20 may be knocked by a tool such as a hammer, and when the positioning rod 20 is pressed by an external force, the positioning plate 22 may be deformed in the positioning hole 12, and after the positioning plate 22 smoothly passes through the positioning hole 12 and enters below the positioning table 13, the positioning plate 22 may be restored to the original state, and the locking with the positioning table 13 may be achieved.
