Road construction process
The invention discloses a road construction process which solves the problem that differential settlement occurs in the center area and the two sides of a road. According to the technical scheme, theroad construction process is characterized by comprising the following steps: S1, excavating a first foundation pit; S2, arranging a first foundation pit strengthening structure; S21, conducting a pile position lofting of a first cement mixing pile; S22, arranging a first cement mixing pile according to the pile position lofting point; S23, before the first cement mixing pile is solidified, excavating a plurality of transverse grooves longitudinally at intervals of at least one set of first cement mixing piles in a way that at least one set of first cement mixing piles are located in the transverse grooves; S24, laying a first reinforcing part in the transverse groove, wherein the first reinforcing part is provided with a first reinforcing part; S25, filling and tamping the transverse grooves with undisturbed soil and tamped; S3, laying a first light soil layer; S4, laying a first stable layer; and S5, laying a first surface layer. The central area and the two side areas of the road manufactured according to the road construction process are not prone to differential settlement.
本发明公开了一种道路施工工艺，解决了道路中心区域和两侧发生不均匀沉降的问题。其技术方案要点是一种道路施工工艺，包括如下步骤：S1、开挖第一基坑；S2、设置第一基坑强化结构：S21、进行第一水泥搅拌桩的桩位放样；S22、根据桩位放样点，设置第一水泥搅拌桩；S23、待第一水泥搅拌桩凝固之前，纵向间隔至少一组第一水泥搅拌桩开挖多个横向沟槽，且至少存在一组第一水泥搅拌桩位于横向沟槽内；S24、在横向沟槽内铺设第一强化件，第一强化件具有第一强化部；S25、使用原状土将横向沟槽填满并夯实；S3、铺设第一轻质土层；S4、铺设第一稳定层；S5、铺设第一面层；根据上述所述道路施工工艺制造的道路的中心区域和两侧区域不易发生不均匀沉降。
