Construction method for treating coastal backfill super-thick gravel soil foundation
The invention relates to the technical field of foundation treatment construction, in particular to a construction method for treating a coastal backfill super-thick gravel soil foundation. The method comprises the steps that firstly, construction preparation is conducted, a foundation treatment site is arranged, leveling and measuring are conducted, and the ramming elevation is determined; secondly, point tamping construction is conducted for the first time, and the energy level is 18000 kN * m; thirdly, the second time of point tamping staggered construction is conducted, and the energy level is 18000 kN * m; fourthly, the third time of point tamping staggered construction is conducted, and the energy level is 10000 kN * m; fifthly, after the site is leveled, hydraulic rammer construction is adopted; sixthly, effect detection is carried out; seventhly, supplementary ramming is conducted; and 8, vibrating and rolling. According to the method, the ultra-thick backfill gravel soil is treated through combination of ultrahigh-energy-level dynamic compaction and hydraulic compaction, the coastal area backfill foundation with the depth of 22 m can be treated at a time, and the method has the advantages of being obvious in treatment effect, even in later-period sedimentation, simple in process, short in construction period, environmentally friendly and the like.
本发明涉及地基处理施工技术领域，特别涉及一种处理沿海回填超厚碎石土地基的施工方法。第一步：施工准备，整理地基处理场地，进行平整和测量，确定起夯标高；第二步：第一遍点夯施工，能级采用18000kN·m；第三步：第二遍点夯错位施工，能级采用18000kN·m;第四步：第三遍点夯错位施工，能级采用10000kN·m；第五步：场地平整后采用液压夯施工；第六步：效果检测；第七步：补夯；第八步：振动碾压。本发明采用超高能级强夯联合液压夯进行处理超厚回填碎石土，可以一次性处理深达22m厚度的沿海地区回填地基，具有处理效果明显、后期沉降均匀、工艺简单、工期短和环保等特点。
