老长生堰桥是我县境内黄塘河上一座最长的石板桥,全桥27孔,桥长130米,长山河道经过该段老河道,因此,长生堰桥必须重新建造。新的长生堰桥确定采用3×40米桁架拱桥。建造这座大桥,工程量大,两个中墩必须在大河的水面上施工,困难很大。采用了水中埋置钢丝网薄壳护筒钻孔灌注桩的施工工艺,解决了中墩桩基施工的技术关键。长生堰桥的全部工程,仅用了七个半月的时间,拆除了老桥,建成了新桥。较一九七八年在陆地建造同
The Old Changsheng Weir Bridge is the longest stone bridge on the Huangtang River in the county. There are 27 holes in the bridge and the bridge is 130 meters long. The Changshan River passes through the section of the old river. Therefore, the Changsheng weir bridge must be rebuilt. New Changsheng weir bridge to determine the use of 3 × 40 meters truss arch bridge. The construction of the bridge, a large amount of construction, the two pier must be constructed on the surface of the river, difficult. Adopting the construction technology of the embedded bored cast-in-place piles with steel mesh embedded in the water, the technical key to the construction of the piled pile foundation is solved. The entire project of the Changsheng weir bridge, only took seven and a half months, demolished the old bridge, completed the new bridge. More on land than in 1978
