Thermal-insulation roadbed construction method
The invention discloses a thermal-insulation roadbed construction method. The thermal-insulation roadbed comprises a roadbed base layer, an asphalt pavement layer, side slope base layers and slope heat preservation concrete layers. The asphalt pavement layer is arranged on the roadbed base layer with a trapezoidal cross section; the side slope base layers are arranged on the two sides of the roadbed base layer. The slope heat preservation concrete layers are arranged on the outer side slope surfaces of the side slope base layers and are provided with reinforcing pipe piles which are perpendicular to the side slope surfaces and obliquely penetrate the side slope heat preservation concrete layers and the side slope base layers in sequence. The side slope heat preservation concrete layers areprovided with reinforcing pipe piles perpendicular to the side slope faces and the reinforcing pipes extend to the roadbed base layer, so that the side slope heat preservation concrete layers and theside slope base layers are firmer under the action of the reinforcing pipe piles, the relation between the side slope heat preservation concrete layers and a roadbed is enhanced, the integrity of theroadbed is enhanced, and the settlement difference between the roadbed and a side slope is reduced. The stability and the anti-sliding capacity of the whole newly-built roadbed slope are enhanced, and cracks formed on the surface of the side slope heat preservation concrete layers are restrained.
一种保温路基施工方法，保温路基包括：路基基层、沥青路面层、边坡基层、边坡保温混凝土层，路基基层截面呈梯形，其上设置沥青路面层，路基基层两侧设置有边坡基层，边坡基层外侧坡面设置有边坡保温混凝土层，边坡保温混凝土层还设置有垂直于边坡坡面依次斜穿过边坡保温混凝土层和边坡基层的加强管桩，边坡保温混凝土层设置有垂直于边坡面依的加强管桩，并一直延伸至路基基层中，使得边坡保温混凝土层在加强管桩作用下与边坡基层之间更加牢固，加强了边坡保温混凝土层路基之间的联系，增强了路基的整体性，减小了路基与边坡部位的沉降差。增强了整个新建路基边坡的稳定性和抗滑移能力，抑制边坡保温混凝土层表面形成裂缝。
