One-way water guide anti-clogging drain hole structure
The invention relates to a one-way water guide anti-clogging drain hole structure. The method is suitable for water-passing buildings in civil engineering, hydropower and water conservancy projects. According to the technical scheme, the one-way water guiding anti-clogging drainage hole structure is characterized by comprising a drainage pipe inserted into a drainage hole in a bottom plate of a water passing building; the orifice water guide protective cover is mounted at the upper end of the drain pipe; when the water pressure in the surface of the water-passing building is greater than the water pressure outside the drainage hole, the orifice water-guiding protective cover can tightly press and seal the pipe orifice at the upper end of the drainage pipe under the action of pressure difference; when the water pressure in the surface of the water passing building is smaller than the water pressure outside the drainage hole, the hole opening water guiding protection cover can be lifted under the action of pressure difference, and therefore a drainage channel communicating the drainage pipe with a water passing channel of the water passing building is formed between the hole opening water guiding protection cover and the drainage pipe.
本发明涉及一种单向导水防淤堵排水孔结构。适用于土木、水电水利工程中的过水建筑物。本发明所采用的技术方案是：一种单向导水防淤堵排水孔结构，其特征在于，包括：排水管，插装于过水建筑物底板上的排水孔内；孔口导水防护盖，安装于所述排水管上端；所述孔口导水防护盖在过水建筑物表面内水压力大于排水孔外水压力时，能在压差作用下压紧封闭排水管上端管口；所述孔口导水防护盖在能在过水建筑物表面内水压力小于排水孔外水压力时，能在压差作用下被抬升，从而在孔口导水防护盖和排水管之间形成连通排水管和过水建筑物过水通道的排水通道。
