Soft soil foundation expressway widening construction method
The invention relates to the technical field of building construction, and discloses a widening construction method for a soft soil foundation expressway. Before the original drainage side ditch is dismantled, primary construction of a new drainage side ditch is completed; the original road structure in the splicing widening construction range is dismantled; digging out a soil layer at the bottom of the new roadbed in the widening construction range; carrying out step excavation on the original roadbed; waste earthwork of the subway foundation pit is used for backfilling and treatment; the prestressed pipe piles are constructed; constructing a geogrid; foam concrete is poured; clay covered edges are constructed; pouring a reinforced concrete slab; constructing a pavement structure; constructing an embankment protection structure; and prefabricated assembling blocks of the new drainage side ditch are constructed. The overall load of the highway widening structure can be reduced, sedimentation of the highway widening section is relieved, uneven road surfaces caused by different sedimentation of new and old road surfaces are avoided, the service life of the highway is prolonged, and the safety and comfort of vehicle driving are improved.
本发明涉及建筑施工技术领域，公开一种软土地基高速公路拼宽施工方法。拆除原排水边沟前，完成新排水边沟的初步施工；对拼宽施工范围内的原道路结构进行拆除；对拼宽施工范围内的新路基底部土层进行挖除；对原路基进行台阶开挖；使用地铁基坑的废弃土方回填并处理；施工预应力管桩；施工土工格栅；浇注泡沫混凝土；施工黏土包边；浇注钢筋混凝土板；施工路面结构；施工路堤防护结构；施工新排水边沟的预制拼装块。本发明可减轻公路拼宽结构的整体载荷，缓解了高速公路拼宽段的沉降，避免了新旧路面沉降不同导致的路面不平，延长了高速公路的使用寿命，提高了车辆驾驶的安全性和舒适度。
