Abstract

The invention discloses a self-locking assembling type prefabricated road roadbed die. A die main body is roughly of a rectangle shape, and a roughly rectangular inner cavity is formed inside the die main body; the side faces where the short edges of the inner cavity are located are provided with convex portion forming portions protruded towards the outside of the inner cavity, the convex portion forming portions and the two side faces where the long edges of the inner cavity are located jointly form concave portion forming portions, and the shapes of the convex portion forming portions are matched with the shapes of the concave portion forming portions. According to the self-locking assembling type prefabricated road roadbed die, the convex portion forming portions and the concave portion forming portions which are matched with one another are arranged, so that when multiple prefabricated road roadbeds fabricated by the convex portion forming portions and the concave portion forming portions are assembled in a matched manner, due to mutual match between the two heterogeneous parts of the convex portions and the concave portions, relative movement does not happen easily, and therefore match reliability can be effectively guaranteed; and density and stability of the roadbeds can be guaranteed assisted by concrete pouring, and problems that in the prior art, an assembled type roadbed is insufficient in stability, prone to road surface cracking and the like are solved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a self-locking assembled prefabricated road subgrade mold. Background technique [0002] According to the norms of road traffic construction, the current road can be divided into multiple structural levels. The usual roads can be divided into surface layer, base layer, subbase layer and subgrade from top to bottom. The surface layer is directly in contact with the atmosphere, vehicles and pedestrians, and requires high strength, rigidity, flatness, anti-skid, wear resistance, etc.; the base layer The subbase is the main load-bearing structure of the road, which plays an important role in bearing the tensile stress; while the subgrade is the layer directly in contact with the soil foundation. A good subgrade structure should have stable characteristics and be able to adapt to a certain degree of geological changes. Thereby ensuring the health of the upper road surface. ...
