Foundation treatment method based on vibroflotation compaction method
The invention discloses a foundation treatment method based on a vibroflotation compaction method. The foundation treatment method comprises the steps that the incidence relation between the vibration remaining time of a vibroflotation device and the depth of the vibroflotation device in a pile hole, the incidence relation between the compaction current of the vibroflotation device and the depth of the vibroflotation device in the pile hole and a first vibration remaining time adjustment value are preset; a pile hole is formed in the construction position of the vibroflotation compaction sand pile through a vibroflotation device; construction of a vibroflotation compaction sand pile is conducted in the pile hole through a vibroflotation device; the current depth of the vibroflot in the pile hole is monitored, the vibroflot is controlled to carry out vibroflot at the current depth, when the vibration remaining time of the vibroflot reaches a vibration remaining time set value, the compaction current of the vibroflot is compared with a compaction current set value, and if the vibration remaining time does not reach the compaction current set value, the compaction current of the vibroflot is controlled; the vibroflot is controlled to continuously vibroflot for the time equal to the first vibration remaining time adjustment value; and the operation is repeated until construction of the vibroflotation compact sand pile is completed through the vibroflotation device. The construction efficiency and the construction quality of foundation treatment can be improved.
本发明公开了一种基于振冲密实法的地基处理方法，包括：预先设定振冲器的留振时间与振冲器在桩孔中所处深度之间的关联关系，振冲器的密实电流与振冲器在桩孔中所处深度之间的关联关系以及第一留振时间调整值；通过振冲器在振冲密实砂桩的施工位置上制造桩孔；通过振冲器在桩孔内部进行振冲密实砂桩的施工；监测振冲器在桩孔内所处的当前深度，控制振冲器在当前深度下进行振冲，待振冲器的留振时间达到留振时间设定值，将振冲器的密实电流与密实电流设定值进行比较，如未达到密实电流设定值，控制振冲器持续振冲与第一留振时间调整值相等的时间；重复直至通过振冲器完成对振冲密实砂桩的施工。本发明可以提高对于地基处理的施工效率和施工质量。
