Road cornerstone

Abstract

The invention relates to a road cornerstone which comprises an insertion-connecting head (1), an insertion-connecting head (2), a hollow part (3) inside the road cornerstone, a pedestrian part (4) ofthe opening of the road cornerstone and a cement concrete part (5). The insertion-connecting head (1) and the insertion-connecting head (2) are of rectangles, the length and the width of the insertion-connecting head (1) are slightly smaller than those of the insertion-connecting head (2); the hollow part (3) inside the road cornerstone is of a trapezoid; the length of the cement concrete part (5)is 2-3 centimeters; the insertion-connecting head (1) is arranged in the insertion-connecting head (2); and the pedestrian part (4) of the opening of the road cornerstone is embedded in the insertion-connecting head (1) or the insertion-connecting head (2). Every road cornerstone is connected to another in such a mode with the number as required; and when pressing a roadbed in the ground, the hollow part (3) inside the road cornerstone is embedded in the ground and just filled with cement concrete on the ground. The invention is nonpoisonous and harmless and has environmental protection, sanitation, strong strength, convenient installation, and no irregularity of the road cornerstones after installation.

Description

Technical field: [0001] The invention relates to a road bedrock. Background technique: [0002] At present, most of the subgrade stones installed on both sides of many traffic roads are processed with natural stone materials. The most important thing is that they are generally processed into square shapes. posed a safety hazard. Moreover, the colors are relatively single. Some of the natural stone colors are painted with a layer of paint at most, which not only has an impact on environmental protection, but also fades for a long time, and the effect is very poor. Invention content: [0003] The purpose of the present invention is to provide a road subgrade stone, which is non-toxic, harmless, environmentally friendly and hygienic, high in strength, easy to install, and will not cause unevenness between each piece after installation. [0004] In order to solve the existing problems of the background technology, the present invention adopts the following technical solution...
