The tetrahedral and hexagonal permeable frame is a closed frame structure, which has been applied in many rivers such as the Yangtze River, the Yellow River and the Weihe River in China. It has a good effect of energy dissipation and deceleration, erosion prevention and siltation promotion for bank protection, beach protection, bottom protection and pier protection in river regulation projects. In the Yangtze River waterway regulation project, the tetrahedral and hexagonal permeable frame has been widely used because of its remarkable effects on the edge protection of soft mattress and scour prevention of dam head.

四面六邊透水框架桿件通過外露的鋼筋焊接構成的錐頂部結構。當其拋于岸邊或灘邊時，在一定水位時，錐頂處鋼筋焊接尖角成為水下危險源，對船舶航行或靠岸產生較大的安全隱患；位于一定高程以上的框架，由于每年均有一段時間露出水面，鋼筋焊接處極易銹蝕，導致框桿散落、結構破壞，嚴重影響了框架使用壽命和河道整治效果。

The pyramid top structure is formed by welding the four sided and six sided permeable frame members with exposed reinforcement. When it is thrown on the shore or beach, at a certain water level, the welding sharp corner of the steel bar at the top of the cone becomes an underwater hazard source, which has a great potential safety hazard for the navigation or landing of the ship; As the frame above a certain elevation is exposed to the water for a period of time every year, the welding part of the reinforcement is easy to rust, resulting in scattered frame bars and structural damage, which seriously affects the service life of the frame and the effect of river regulation.

透水框架采用桿件組合焊接工藝是指，透水框架由多根桿件組合焊接而成。透水框架焊接處形成尖角，對施工人員易造成作業傷害，安全風險較高；此外，桿件鋼筋外露，易銹蝕、斷裂，造成透水框架解體，影響岸坡護腳整體質量。擬限制使用，規定在大、中型水運工程中不得使用。

The combination welding process of members is adopted for the pervious frame, which means that the pervious frame is formed by the combination welding of multiple members. The sharp corner formed at the welding point of the pervious frame is easy to cause operation injury to the construction personnel, and the safety risk is high; In addition, the exposed bar reinforcement is easy to rust and fracture, causing the disintegration of the pervious frame and affecting the overall quality of the bank slope toe protection. It is planned to restrict its use, and it is stipulated that it shall not be used in large and medium-sized water transport projects.
