Embedding structure and method for preventing cracking of concrete pavement luminous marks

Abstract

The invention discloses an embedding structure and method for preventing cracking of concrete pavement luminous marks. A step-shaped groove is embedded in a pavement, luminous marks are uniformly arranged on the upper surface of a precast concrete member, PVC casing pipes are arranged in holes on one side of a shaping plate type component, reinforcing steel bars are arranged in holes on the otherside, a drainage groove is formed in the middle of the upper surface of the precast concrete member, strip-shaped grooves are formed above a joint at equal intervals, drilling holes are formed at bothends of the strip-shaped grooves, the middle parts of horseshoe ribs are matched with the strip-shaped grooves, both ends of the horseshoe ribs are arranged in the drilling holes, second equilateralangle steels are arranged on the upper surface of the precast concrete member and are symmetrically distributed along the drainage groove, first equilateral angle steels are perpendicularly arranged on both sides of the second equilateral angle steels, the luminous marks are arranged between the first equilateral angle steels and the second equilateral angle steels, and an asphalt layer is arranged above the pavement. The anti-reflection crack performance of the concrete surface layer where the luminous marks are buried can be improved, and the width and expansion of concrete pavement cracks are reduced.

Description

technical field [0001] The invention relates to the technical field of traffic facilities, in particular to an embedding structure and method for preventing cracks at luminous signs on concrete pavement. Background technique [0002] Compared with asphalt concrete pavement, cement concrete pavement has excellent deformation resistance and water stability. At the end of the last century, cities built a large number of cement concrete pavements. Embedding luminescent signs at the zebra crossings at urban road intersections can effectively warn "head-down people" and reduce the traffic accident rate at intersections. The pavement embedding method of existing pavement signs is to excavate a groove of a certain size in the existing pavement, and then position the cast iron box at the bottom of the light-emitting device on a straight line through the two parallel channel steels at the bottom, and then start pouring concrete in layers It is compacted and formed, maintained, and fi...
