衛河是行船較多的河道,水尺标志对安全行船有很重要的意义,以往由于按装方法較麻煩易損坏,所以有时竟麻痺大意不设置,以致造成55年沉船事故。最近我站試用了一种重錘式水尺标志;現將制作方法介紹于下: 用竹杆一支,長度視需要而定,直徑1.5～2.0公分,底端用細鉄絲懸吊一重物(石塊或鉄塊均可),重物体積不宜过大以免纏水草。在竹杆上適当位置鑽一孔,用軸釘一支穿过孔眼(孔眼与軸釘接触处应尽量灵活,使竹杆可以自由轉动)釘在木樁上,木樁打入河中需要标志的地点,全部装置如圖所示。
The Wei River is a river with more ships. The water mark is of great significance to the safety of the boat. In the past, the loading method was troublesome and easily damaged, so it was sometimes not useful to set up paralysis, resulting in a 55-year-old shipwreck. Recently, I tried a hammer hammer-style watermarks; now introduced in the production methods below: a bamboo pole, length as needed, the diameter of 1.5 to 2.0 cm, the bottom with a thin wire hanging a heavy object (Stone or stone block can be), weight should not be too large volume to avoid wrapping water. Drill a hole in a suitable place on the bamboo pole and use a shaft pin to pass through the hole (the contact between the hole and the shaft pin should be flexible so that the bamboo pole can rotate freely) Nailing on the wooden pile, The location, all devices as shown.
