目前黄河壩埽護岸多為石工,每經一次洪水壩埽根石即發生若干變化,不但根石走失损失巨大,而且造成不同險情,甚至影響堤壩安全。目前我們对根石的維護和护底工作尚缺乏有系統的成熟經驗,菏澤段職工同志們這種鑽研改進精神和初步成就是值得全河職工同志学習和繼續研究改進的。 At present, most of the Yellow River dam 埽 revetments are masonry. Each time a flood dam 埽 root stone undergoes some changes, not only the losses of the root stone are huge, but also cause different dangerous conditions and even affect the safety of the dam. At present, we still do not have systematic and mature experience in the maintenance and protection of roots. This spirit of dedication and preliminary achievements made by employees and workers in Heze is worth studying and continuing to study and improve.
