过去木材水运都用杉木做渡架,借助杉木浮力进行水运。在杉木缺少情况下,木材水运能不能甩掉渡架?杉溪转运站工人、干部坚持实践的观点,发现了提高松木浮力和最大限度的利用松木浮力进行水运的客观规律,创造了无渡架放排法。一、提高松木浮力松木的浮力大小和浮沉时间,主要受着干湿度的影响。对松木干湿度的影响有多方面的因素,如生长密度,有没有采割松脂,采伐季 In the past, wood was used to make wooden truss, with the help of Chinese fir buoyancy. In the case of the lack of Chinese fir, timber water transport can not get rid of crossing the bridge? Sugi Station transfer workers, cadres adhere to practice point of view, found to improve the buoyancy of pine and maximize the use of pine buoyancy for the objective law of water transport, creating a transitional Discharge method. First, improve the buoyancy of pine buoyancy pine size and floating time, mainly affected by the impact of humidity. There are many factors that affect the dry and wet pine, such as the density of growth, whether or not to cut the turpentine, the cutting season
