(接上期)施工注意事项试挖孔地质情况对挖桩孔工法和工期有很大的影响,因此在正式挖桩孔之前要试挖,与地质勘察的结果进行对照,确认地质和持力层情况。同时在挖桩孔过程要检验排出土渣的情况并记入挖孔记录表,分析与勘察结果有无差异。如有差异出现,必须研究其状况并对挖桩孔工法及循环时间等重新进行研究,为以后孔段的施工参考。
(Continued) Construction Notes Drilling hole geological conditions on the method of excavation hole and the construction period has a great impact, so in the formal excavation holes to dig before digging, and geological reconnaissance results contrast to confirm the geological and holding layer Happening. At the same time in the process of digging pile holes to test the situation of discharge of soil and digging hole record table, analysis and survey results are there any differences. If any discrepancy occurs, it is necessary to study its condition and re-study the method of hole digging and the cycle time so that it can be used as reference for future construction of holes.
