Steep slope section inverted siphon arrangement structure and construction method
The invention relates to the technical field of water conservancy facilities, in particular to a steep slope section inverted siphon arrangement structure and a construction method. The structure comprises a foundation trench arranged on a slope, the bottom of the foundation trench is horizontally arranged, the width of the bottom of the foundation trench is larger than the outer diameter of an inverted siphon, a plurality of anchor bars are inserted into the bottom of the foundation trench, one end of each anchor bar is perpendicular to the bottom of the foundation trench and inserted into bed rock, the other end of each anchor bar is located in the foundation trench, a concrete base is arranged at the bottom of the foundation trench, the anchor bars are embedded in the concrete base, a pipe groove with a semicircular section is formed in the concrete base, an inverted siphon is laid in the pipe groove, outer wrapping concrete with a semicircular section is arranged on an exposed semicircular outer surface of the inverted siphon, and the outer wrapping concrete is connected with the concrete base in a matched mode to wrap the inverted siphon. The arrangement and use stability of the inverted siphon on the steep slope can be effectively improved, the full-wrapping type temperature protection effect on the inverted siphon can be achieved, and the pipe wall of the inverted siphon is prevented from generating cracks due to the temperature difference.
本发明涉及水利设施技术领域，具体涉及一种陡坡段倒虹吸管布置结构及施工方法。结构包括设于斜坡上的基槽，所述基槽的槽底水平设置，且槽底的宽度大于倒虹吸管的外径，所述基槽的槽底插设有若干锚筋，所述锚筋的一端垂直于基槽的槽底插入基岩中，另一端位于基槽内，所述基槽的槽底设有混凝土基座，所述混凝土基座将锚筋掩埋，在混凝土基座上设有截面呈半圆形的管槽，所述管槽内铺设倒虹吸管，在倒虹吸管的外露半圆外表面设有截面呈半圆形的外包混凝土，所述外包混凝土与混凝土基座匹配接合，将倒虹吸管包裹。本发明可以有效提高倒虹吸管在陡坡上布置使用的稳定性，并且可以对倒虹吸管起到全包裹式的温度保护作用，防止其管壁因温差而产生裂缝。
