Buried pipe structure under mask earth and rockfill dam and construction method thereof
The invention relates to a buried pipe structure under a mask earth and rockfill dam and a construction method thereof. According to the buried pipe structure under the mask earth and rockfill dam and the construction method thereof, the influence of external factors on buried pipes under the mask earth and rockfill dam is reduced, meanwhile, inspection and maintenance of later operation and maintenance personnel and later reconstruction and extension are facilitated, and the buried pipe structure has the remarkable characteristics of being easy and convenient to construct, good in durability, capable of saving energy, environmentally friendly, good in foundation adaptability and the like. According to the technical scheme, the buried pipe structure under the mask earth and rockfill dam is characterized in that the buried pipe structure is provided with a concrete prefabricated pipe gallery arranged at the bottom of the earth and rockfill dam, the upstream end of the gallery is blocked by a concrete fixing pier, an anti-corrosion steel pipe penetrating through the concrete fixing pier is arranged in the gallery in a full-length mode, the anti-corrosion steel pipe is formed by connecting a plurality of sections of steel pipes through expansion joints in a segmented mode, the concrete prefabricated pipe gallery is formed by connecting a plurality of prefabricated concrete pipes in a lap joint mode, and differential settlement of an earth and rockfill dam foundation is dealt with through deformation of the lap joint positions of the prefabricated concrete pipes.
本发明涉及一种面膜土石坝坝下埋管结构及其施工方法。本发明的目的是提供一种面膜土石坝坝下埋管结构及其施工方法，减少外界因素对坝下埋管的影响，同时方便后期运维人员的检查与维修，以及后期改建与延长，具有施工简便、耐久性好、节能环保及地基适应性好等显著特点。本发明的技术方案是：一种面膜土石坝坝下埋管结构，其特征在于：具有布设于土石坝底部的混凝土预制管廊道，该廊道上游端由混凝土固定墩封堵，廊道内部通长布置有贯穿混凝土固定墩的防腐钢管，该防腐钢管由若干段钢管经伸缩节分段连接而成，所述混凝土预制管廊道由若干预制混凝土管搭接而成，并通过所述预制混凝土管的搭接位置变形来应对土石坝坝基的不均匀沉降。
