长江下游南京浦口下关段于1955年1月开始,分三期进行沉排护岸工程,至1957年3月竣工,完成坍势严重地段约计6公里,开我国有史以来深水沉放大排之先例。在施工过程中,对沉排操作及质量,均有显著提高,三期工程虽然同样采用锚定船与定位船作为控制柴排下沉的主要设备,可是在具体装制和应用上,各期都有不同的改进。例如:锚定船的装置,减少摇车,添设推关,减少两船之间联系的驳缆,既节约人力物力,而且便于操作;对实沉排位影响很大的抛投压排石的操作,也是一项成功的经验,一期工程定位船不能移动,二期工程实施时,当柴排上游没水后,定位船移动前进,利用它继续抛投压排石,所有木船,编号
The lower section of the lower reaches of the Yangtze River in Pukou, Gansu Province, started in January 1955 and carried out bank-sinking of bank protection in three phases. It was completed in March 1957 and completed a severe break of about 6 km in length, opening up a precedent for deep water drainage in the history of our country. During the construction process, both the operation and the quality of the sinking row have remarkably improved. Although the third phase of the project also uses the anchoring ship and the positioning ship as the main equipment for controlling the sinking of the rowing bunker, in the concrete installation and application, There are different improvements. For example: anchoring the ship’s equipment, reducing the car, add the push off, reducing the connection between the two boats, both manpower and material resources savings, and ease of operation; Operation, but also a successful experience, a project positioning ship can not move, the second phase of the project implementation, when the upper reaches of Chai after no water, the positioning ship move forward, use it to continue to throw castaway stone, all wooden boats, number
