Rock-soil sampling method
The invention discloses a rock-soil sampling method, which relates to the technical field of rock-soil engineering, and comprises the following steps that a unit depth is drilled vertically downwardsfrom the ground, and rock-soil in a hole is taken away; concrete is poured into the drilled hole, and a cast-in-place pile is formed after the concrete is solidified; a unit depth is drilled downwardsfrom the center of the cast-in-place pile, and a concrete sample is taken away; and the above steps are repeated until a specified depth is reached, and rock soil at the bottom of the hole is drilledand taken as a final sample, wherein when the concrete sample is taken away each time, a unit depth is drilled downwards with the bottom surface of the drilled hole as the reference, and concrete needs to be poured after each unit depth is drilled. When concrete is poured, a mode of circularly pumping the concrete into the hole is adopted. The hole wall can be effectively protected in the drilling process, the safety of the drilling process is improved, and normal operation of the drilling sampling process is guaranteed.
本发明公开了一种岩土取样方法，涉及岩土工程技术领域，其包括以下步骤：由地面垂直向下钻取一个单位深度，并取走孔内岩土；向钻孔内灌注混凝土，等待混凝土凝固，形成灌注桩；由灌注桩中心向下钻取一个单位深度，并取走混凝土试样；以及重复上述步骤，直到钻至指定深度后，钻取孔底的岩土作为最终试样；其中，每取走一次混凝土试样，均以钻孔的底面为基准向下钻取一个单位深度，且每钻取一个单位深度后均需灌注混凝土。灌注混凝土时，采用向孔内循环泵送混凝土的方式。本发明能够在钻孔过程中对孔壁进行有效保护，提高钻孔过程的安全性，保证钻孔取样过程的正常进行。
