一、引 言 我县在华主席、党中央的抓纲治国方针指引下,坚持党的基本路线,坚持农业学大寨的群众运动,在1977年度秧花江治涝工程中,一个冬春完成土方230万立米,佔涝区疏河筑堤总土方568.9万立米的41.5%。可是成堤以后,还需继续完成堤下涵42座,59孔、总净宽179.6米,工程量较大。设计这项工程,我们学习了本地区和外地先进经验,针对涝区基础承载力较低,石料来源困难的情况,涵身设计采用了预制构件双曲拱马蹄形涵。出入口推广使用连洪挡土墙,并改革施工程序,用吊拍门代替沿用的叠梁门、双掩门。
I. INTRODUCTION Under the guiding principle of running the country by the Chinese government and the party Central Committee, our county upholds the Party’s basic line and upholds the mass movement of learning Dazhai in agriculture. In 1977, during the flood control project of the Sijiahua River, a county in spring and spring completed earthwork 230 Million cubic meters, accounting for 41.5% of 5.689 million cubic meters of total earthwork of the river embankment in the flood-prone area. However, after the embankment, we still need to complete the construction of 42 embankments and 59 holes, with a total net width of 179.6 meters and a large amount of works. In designing this project, we learned advanced experience in the region and in the field. In view of the low foundation bearing capacity and the difficult sources of stone in the floodplain, the culvert design uses the prefabricated double-arch arch hoof hoof. The entrance and exit to promote the use of even the retaining wall, and the reform of construction procedures, with hanging grate instead of the use of folding doors, double-door.
