Further, a plurality of reinforcing ribs are connected between the two ribs at intervals, and the top surfaces of the reinforcing ribs are flush with the ribs.
The utility model has the beneficial effects that:
according to the utility model, the expansion side plate is added, and is installed at the position where a steel pipe gap exists, so that the gap on the side surface of the plate frame body is plugged, and the problem that the potential safety hazard exists in the gap of the original plate frame is avoided; the expansion head plate has the function of forming slope transition at the joint of the plate frame body with the height difference at part, thereby avoiding steps and improving the passing safety.

Detailed Description
The utility model is further described below with reference to the accompanying drawings:
as shown in fig. 1 and 2, an expandable grillage for grotto repair comprises a grillage body 1, wherein a plurality of convex connecting pieces 4 are arranged on the left side surface and the right side surface of the grillage body 1, and the connecting pieces 4 are distributed at equal intervals. As shown in fig. 5, the connecting piece 4 is an L-shaped fixing rod, the short side of the L-shaped fixing rod is perpendicular to the plate frame body 1, and the long side of the L-shaped fixing rod is parallel to the plate frame body 1.
The left side face and the right side face of the plate frame body 1 are connected with a plurality of strip-shaped expansion side plates 2, the expansion side plates 2 are detachably connected with the connecting pieces 4, and the top faces of the expansion side plates 2 are flush with the top face of the plate frame body 1. The side of the expansion side plate 2 is horizontally fixed with sleeves 5 corresponding to the connecting pieces 4 one by one, and when the expansion side plate 2 is connected with the plate frame body 1, the long sides of the L-shaped fixing rods penetrate through the sleeves 5. 3-5 extension curb plates 2 can be connected to every grillage body 1 unilateral, and the width of extension curb plate 2 equals the steel pipe external diameter, and the convenient shutoff is owing to wear to establish the gap that the steel pipe produced.
