Description

Permeable frame and three-dimensional interlocking assembled pavement base layer

Technical Field

The utility model belongs to the technical field of permeable pavement, and relates to a permeable frame and a three-dimensional interlocking assembled pavement base layer.

Background

The permeable frame is a pavement base material with a strong permeable function, and is paved below pavement bricks and above a roadbed layer. The water permeability is realized in two main modes, namely through pores among particles in the frame and through holes or gaps in the frame structure. The permeable frame is an important material for constructing permeable pavement, so that rainwater can quickly infiltrate downwards, the accumulated water on the pavement in rainy days is reduced, and the underground water is replenished.

The existing permeable frame is generally directly paved on a ground roadbed, and in the use process, the frame is easy to loosen due to the load effect of pedestrians and vehicles, the infiltration of rainwater into a leveling layer below and the like. Frequent loosening of the brick body affects the travel feeling of the pedestrian, and the situation that the pedestrian carelessly bends the feet or wets the footwear in rainy days often occurs. When riding through loose floor tiles, even a non-motor vehicle can be out of control, and personal safety is endangered.

In order to solve the technical problems, chinese patent literature discloses an utility model patent of interlocking grass planting bricks, and the application number is 201420664514.2. The side surfaces of the brick bodies realize mutual clamping between adjacent brick bodies through concave-convex openings, so that the brick bodies are prevented from sideslip dislocation. This design limits the movement of the brick in the horizontal direction, but when the road load or ground water level rises, the brick is subjected to upward forces, interlocking only in the horizontal direction is insufficient to form a stable road surface structure.
