量冰花工具的构造,用一根适当长的木杆(或测深杆),在其下端六公寸处钻一小孔,再用一根小绳,一端系于木杆小孔处,一端系于木板中央。木板长一公尺、宽七公分,板的一端拴一条适当长的小绳,以作拉放木板之用(如图)。量冰花时首先将提放木板的小绳拉紧,使木板与木杆重叠,再将木杆插入冰孔内,使杆头放入河底或所需适当位置后松绳约七公寸,木板和木杆成垂直,而上提木杆,提不动时即可量出冰花厚度。
The amount of ice tool structure, with a suitable length of wood (or sounding rod), at the bottom of the six-inch drill a small hole, and then a small rope, one end of the rod in the hole at one end Department of the central board. The plank is one meter long and seven centimeters wide. One end of the plank is tied to a suitably long string for the purpose of being planted with planks (pictured). When the amount of ice will first lift the wooden rope taut so that wood and wood overlap, and then insert the ice into the hole, the club head into the river or the appropriate location after the loose rope about seven inches, Wood and wood into a vertical, while the mention of wood, can be measured when the amount of ice thickness.
