Bored pile deep hole mud sampler and sampling method thereof

The invention discloses a bored pile deep hole mud sampler and a sampling method thereof. The mud sampler comprises a sampling container, a lifting device and a depth measuring device. The sampling method comprises the following steps of: completing drilling, and cleaning a hole; putting down the sampling container; recording the putting position of the sampling container; 4, allowing slurry at the bottom of the hole to enter the sampling container; and 5, lifting the sampling container, and detecting the slurry in the sampling container. According to the mud sampler and the sampling method thereof, the mud at the bottom of a hole can be rapidly sampled, and the sampling efficiency is improved. 本发明公开一种钻孔桩深孔泥浆取样器及其取样方法，所述泥浆取样器包括：取样容器；提拉装置；深度测量装置；所述取样方法包括：钻孔完成，清孔作业；下放所述取样容器；记录所述取样容器的下放位置；步骤4：孔底的泥浆进入所述取样容器中；步骤5：上提所述取样容器，检测所述取样容器中的泥浆。本发明所述的泥浆取样器及其取样方法能够快速的进行孔底泥浆的取样，提高了取样的效率。
