Reinforcing structure and method for flood drainage culvert pipe in tailing pond
The invention discloses a reinforcing structure and method for a flood drainage culvert pipe in a tailing pond, and belongs to the field of tailing pond safety. The problem that the flood drainage culvert pipe in the tailing pond is prone to damaging is solved. A plurality of steel arch rings are tightly attached to the inner wall of the culvert pipe in the length direction of the culvert pipe, the steel arch rings are connected into an integral frame through longitudinal supporting rods, a movable inner slip form formwork is arranged in the culvert pipe, and fiber concrete is poured in the integral frame with the inner slip form formwork as a formwork. The steel arch rings and the longitudinal supporting rods are arranged in the culvert pipe to preliminarily support the culvert pipe body, the fiber concrete is poured in the steel arch rings, the steel arch rings and the fiber concrete powerfully support the culvert pipe, so that the bearing capacity of the culvert pipe is greatly improved, and the safety performance of the tailing pond is guaranteed. The inner slip formwork method is adopted for constructing the fiber concrete, the method is suitable for construction of narrow space in the culvert pipe, a smooth inner wall is formed after construction is completed, and the influence on the flood discharge capacity of the culvert pipe is reduced to the maximum extent.
本发明公开了一种尾矿库内排洪涵管的加固结构及方法，属于尾矿库安全领域，解决了尾矿库内排洪涵管易损坏的问题。本发明紧贴涵管内壁沿涵管长度方向设置有多个钢拱圈，多个钢拱圈之间通过纵向支撑杆连接成整体框架，涵管内设有可移动的内滑模模板，以内滑模模板为模板在整体框架内浇筑有纤维混凝土。本发明在涵管内部设置钢拱圈及纵向支撑杆，对涵管管体形成初步支撑，又在钢拱圈内部浇筑纤维混凝土，钢拱圈和纤维混凝土对涵管形成强有力的支撑，从而极大地提高了涵管的承载力，保障了尾矿库的安全性能。本发明采用内滑模法施工纤维混凝土，适用于涵管内窄小空间的施工，施工完成后形成光滑的内壁，最大限度地减小对涵管泄洪能力的影响。
