技术领域technical field
本发明涉及一种应用于水利水电工程用于深孔弧门顶的两道式止水结构，属于水利水电工程中的水工金属结构技术领域。The invention relates to a two-way water-stop structure applied to the top of a deep-hole arc door in water conservancy and hydropower projects, and belongs to the technical field of hydraulic metal structures in water conservancy and hydropower projects.
背景技术Background technique
深孔弧形工作闸门是水工金属结构重要的组成部分，它是水利水电工程中重要的泄水建筑物，弧门止水装置是保证弧门可靠运行的重要设施，它对高水头、高流速下运行的弧门尤为重要，通常要求止水装置在任何运行条件下要与止水座配合严密，否则将造成止水部分失效而大量漏水，并可能导致闸门振动或边界空蚀等后果。Deep hole arc working gate is an important part of hydraulic metal structure. It is an important drainage structure in water conservancy and hydropower projects. The arc gate water stop device is an important facility to ensure the reliable operation of the arc gate. Arc gates operating at flow rates are particularly important. Usually, the water stop device is required to cooperate closely with the water stop seat under any operating conditions. Otherwise, the water stop part will fail and a large amount of water will leak, which may lead to gate vibration or boundary cavitation.
现阶段深孔弧门通常采用2道P型顶止水结构形式，下道P型止水件设置在门楣埋件上，上道P型止水件设置在门体面板上，该种设置方式在低水头、小孔口弧门上是可行的。但高水头深孔弧门在承受巨大水压力后，由于门叶及支臂等产生径向压缩变形，其变形量一般较大，规范对止水预压缩量采用2mm-4mm范围，故要保证门顶止水严密是很困难的，若为保证顶止水要达到严密止水效果，从而增加止水橡皮的预压缩量，会导致止水橡皮在运行中磨损严重，增大闸门闭门力，这将导致深孔弧门的止水件寿命减小，运行维护成本增加。At present, deep-hole arc doors usually adopt two P-shaped top water-stop structures, the lower P-shaped water-stop is set on the lintel embedded part, and the upper P-shaped water-stop is set on the door body panel. It is feasible on arc doors with low water head and small orifices. However, after the high water head deep hole arc door is subjected to huge water pressure, due to the radial compression deformation of the door leaf and support arm, etc., the deformation is generally large. It is very difficult to seal the water at the top of the door tightly. If the pre-compression of the water-stop rubber is increased to ensure the water-stop at the top to achieve a tight water-stop effect, the water-stop rubber will be severely worn during operation, and the closing force of the gate will be increased. , which will lead to a reduction in the life of the water stop of the deep hole arc door and an increase in operation and maintenance costs.
