1浮漂器探洞法1.1浮漂器的构造浮漂器主要由探杆、细绳、浮漂、吸片及配重组成,如图1所示。预估洞口大致位置确定探杆长度,一般3~6m。探杆粗端直径5cm左右,以用手持握方便为宜。细端每隔0.8m拴一细绳,各绳长由水深确定,一般2~3m,并由外至内递减,使?
1 flotation caving method 1.1 The structure of flotation device Flotation device mainly by the probe, string, float, suction and weight, as shown in Figure 1. Estimate the approximate location of the hole to determine the length of the probe, usually 3 ~ 6m. Probes rough diameter of about 5cm, hand-held to facilitate the appropriate. Thin end every 0.8m tethered a thin rope, the rope length determined by the water depth, usually 2 ~ 3m, and decreasing from the outside to the inside, so?
