Soft soil foundation double-pavement bridge and culvert and construction method thereof
The invention provides a soft soil foundation double-pavement bridge and culvert and a construction method thereof, and belongs to the field of bridges and culverts. Wherein the soft soil foundation double-pavement bridge culvert takes the fourth road section as a boundary, high-pressure jet grouting piles are adopted by the first road section to the third road section to form positions with the best supporting strength, soft soil settlement is controlled, the fourth road section is supported in an auxiliary mode, and a nail-shaped cement soil two-way stirring pile group is used on the fourth road section and matched with a plain soil backfilling process and the like to enhance soil texture. And finally, the thin-wall pipe pile of the fifth road section is matched so that the fourth road section can be subjected to adaptive adjustment before one-time forming, the later-stage settlement condition of the fourth road section can be observed in the construction period, and then later-stage adjustment is conducted. The thought that a high-pressure jet grouting pile is adopted to achieve the optimal strength at a time is omitted from the original position where the soft soil quality is worst, and the defects that construction cannot meet the requirement and later maintenance is difficult due to the fact that the high-pressure jet grouting pile cannot be adjusted after destructively machining the soft soil are overcome.
本发明提供了一种软土地基双路面桥涵及其施工方法，属于桥涵领域。其中软土地基双路面桥涵以第四路段为界，第一路段至第三路段采用高压旋喷桩形成支撑强度最佳的位置，控制软土沉降，并辅助支撑第四路段，而在第四路段使用钉形水泥土双向搅拌桩组并配以素土回填工艺等增强土质，使得第四路段具有较强维护性以及沉降适配性，最后配以第五路段的薄壁管桩使得第四路段能够进行一次成型前的适配调整，在施工周期内可以观察第四路段的后期沉降情况，再进行后期调整。跳脱原有的软土质量最差的位置采用高压旋喷桩来一次性达到最佳强度的思路，避免高压旋喷桩破坏性加工的软土之后无法进行调整导致施工无法达到要求，后期也难以维护的缺陷。
