卫河疏浚工程,自1962年开始筹建,两年多以来,在中央和地方领导部门的重视和支持下,在工程局党委的领导下,在各兄弟单位的大力支援和协作下,全局职工发扬了自力更生、奋发图强的精神,工作取得了比较显著的成绩。截至1964年第三季度止,共完成清淤土方534.8万余立方米的任务;同时,培养出了一支初具规模的机械疏浚队伍;摸索和积累了一定的经验,目前水利电力部正在组织有关单位进行总结。为了满足一些单位的需要,本刊特将“东、西孟姜女河采用索铲施工一次成河的经验”、“用北京号250立方米/时绞吸式挖泥船施工的经验”、“120立方米/时链斗式采砂船用于疏浚河道改装配套的初步经验”等三篇文章先行发表。卫河施工实践证明,索铲用于河道疏浚的优点很多,有比较大的发展前途;特别是当河宽在其开挖半径以内时,可以一次开挖成河,而且造价也低,这是一项好的经验。我们认为,在今后大型灌排渠系建设中,参照东、西孟姜女河的施工经验,进一步加以研究,用索铲来开挖渠道并使之一次成渠,也是有可能的,因此,值得各级水利部门重视和研究。 Wei River dredging project, started construction in 1962, more than two years ago, with the great attention and support of the central and local leading departments, under the leadership of the Party Committee of the Engineering Bureau and with the vigorous support and cooperation of various fraternal units, the entire staff carried forward The spirit of self-reliance, work hard, work has made more significant achievements. Up to the end of the third quarter of 1964, a total of 5,348,000 cubic meters of silt earthwork was completed. At the same time, a well-established mechanical dredging team was cultivated. Some experience was gained and accumulated. At present, the Ministry of Water Resources and Electric Power is organizing Relevant units to be concluded. In order to meet the needs of some units, we hereby publish the “experience of using cable shovel construction in East and West Mengjiang River”, “the experience of using Beijing No. 250 cubic meters / hour cutter suction dredger construction”, “120 cubic meters M / hour chain bucket sand mining vessels used for dredging the first experience in the conversion of the river ”and other articles published three articles. The construction practice of Wei River proves that the cable shovel has many advantages for river dredging and has a relatively large development prospect. In particular, when the river width is within the radius of excavation, it can be excavated into a river at one time, and the cost is also low, which is one Good experience. In our opinion, it is also possible that in the future construction of large-scale irrigation and drainage canal systems, with reference to the construction experience of the East and West Mengjiang River, it is also possible to further study and excavate the channels by means of cable shovels and make them once. Therefore, Grade water conservancy department attaches importance to and research.
