对超深三轴水泥土搅拌桩的配合比进行了室内和现场试验,控制叶片下沉和提升速度在一定范围内,控制每分钟浆液流量达到一定的数值即可满足水泥掺量的要求,从而解决了现场水泥掺量的控制问题;通过改进搅拌头的叶片数量、分布及形状,可以较好地解决桩身底部搅拌不均匀的问题。 The mixing ratio of ultra deep three-axis cement-soil mixing piles was tested indoor and in-field, and the control of the subsidence and speed of the blades was within a certain range. The flow rate per minute reached a certain value to meet the requirements of cement content Which solves the problem of controlling the dosage of cement in the field. The problem of uneven mixing at the bottom of the pile body can be solved well by improving the number, distribution and shape of the blades of the mixing head.
