Embedding structure and method for preventing cracking of concrete pavement luminous marks
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.
本发明公开了一种预防混凝土路面发光标识处开裂的埋设结构及方法，台阶状槽内嵌于路面内，发光标识均匀设于预制混凝土构件上表面，定型板型式构件一侧孔洞内设有PVC套管，另一侧孔洞内设有钢筋，预制混凝土构件上表面中部设有排水槽，条形凹槽等间距的设于接缝上方，条形凹槽两端设有钻孔，马蹄筋的中部与条形凹槽相适配，马蹄筋的两端设于钻孔内，第二等边角钢设于预制混凝土构件上表面，第二等边角钢沿排水槽对称分布，第一等边角钢垂直设于第二等边角钢两侧，发光标识设于第一等边角钢与第二等边角钢之间，沥青层设于路面上方。本发明可以提高埋设发光标识处混凝土面层的抗反射裂缝性能，减小混凝土路面裂缝的宽度以及裂缝的扩展。
