Limestone soil improved roadbed structure
The invention discloses a limestone soil improved roadbed structure which comprises a broken stone hardcore, a limestone soil layer and an asphalt pavement layer which are sequentially compacted and laid from bottom to top, and a plurality of water seepage units embedded in the roadbed structure at intervals, each water seepage unit comprises a bottom frame horizontally arranged on the broken stone hardcore, a plurality of water seepage piles arranged in the lime soil layer in a penetrating mode and a connecting layer arranged between the water seepage piles and the lime soil layer in a filling mode, the upper ends of the water seepage piles extend into the asphalt pavement layer, the lower ends of the water seepage piles are connected to the bottom frame, the water seepage piles are precast piles, and the connecting layer is arranged between the water seepage piles and the lime soil layer. A plurality of protruding edges are arranged on the outer side walls of the water seepage piles, the connecting layer has waterproof performance, and the bottom frame is a prefabricated frame and has water seepage performance. The construction method has the beneficial effects that the roadbed freezing resistance is remarkably improved, the roadbed drainage speed is increased, roadbed settlement and differential settlement are reduced, and pavement diseases are reduced.
本发明公开了一种石灰土改良路基结构，包括从下至上依次压实铺设的碎石垫层、石灰土层、沥青路面层、间隔埋设于所述路基结构内的多个渗水单元，其中，每个渗水单元包括：卧设于所述碎石垫层上的底架、穿设于所述石灰土层内的多个渗水桩、填充于所述渗水桩与所述石灰土层之间的连接层，其中，所述渗水桩上端伸入所述沥青路面层，下端连接于所述底架上，所述渗水桩为预制桩，所述渗水桩外侧壁上设有多个凸棱，所述连接层具有防水性，所述底架为预制架，所述底架具有渗水性。本发明具有显著提升路基抗冻性、加快路基排水速度、减少路基沉降及不均匀沉降、减少路面病害的有益效果。
