Frozen soil freezing depth measuring device and measuring method thereof
The invention relates to a frozen soil freezing depth measuring device and a measuring method thereof. The device comprises an outer pipe, an inner pipe and a measuring solution. The outer pipe is a hollow tubular body with a blocked bottom end, the inner pipe is a transparent hollow tubular body, the inner pipe is installed in the outer pipe in a penetrating mode and is in sliding connection withthe outer pipe, the measuring solution is contained in the inner pipe, and a top end and a bottom end of the inner pipe are blocked through sealing rings. The measuring method comprises the steps ofdigging a deep pit with a depth reaching a lower portion of a frozen soil layer; vertically placing the outer pipe into the deep pit; completely backfilling a gap between the outer pipe and soil; injecting the measuring solution into the inner pipe, sealing the orifice of the inner pipe to prevent the measuring solution from running off, and then making the inner pipe penetrate into the outer pipe; taking out the inner pipe, observing the height of a discoloration section of the measuring solution, and judging a frozen soil freezing depth; making a pipe cap cover the upper ends of the outer pipe and the inner pipe at the same time; during secondary measurement, opening the pipe cap, taking out the inner pipe, and accurately judging the frozen soil freezing depth by observing the height ofthe discoloration section of the measuring solution.
本发明涉及一种冻土冻结深度测量装置及其测量方法，其特点是：它包括外管、内管和测量溶液，所述外管为底端封堵的空心管状体，所述内管为透明空心管状体，内管穿装在外管内且滑动连接，所述测量溶液盛装于内管中，内管顶端和底端以密封圈封堵。测量方法是：开挖深度到达冻土层以下的深坑；将外管竖直置入深坑；完全回填外管与土壤之间的缝隙；向内管注入测量溶液，密封内管的管口以防测量溶液流失，然后将内管穿装在外管内；取出内管观察测量溶液的变色段高度，判断出冻土冻结深度；将管盖同时扣盖在外管和内管上端；再次测量时，打开管盖，取出内管，观察测量溶液的变色段高度，即可准确的判断出冻土冻结深度。
