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.
四面六边透水框架杆件通过外露的钢筋焊接构成的锥顶部结构。当其抛于岸边或滩边时,在一定水位时,锥顶处钢筋焊接尖角成为水下危险源,对船舶航行或靠岸产生较大的安全隐患;位于一定高程以上的框架,由于每年均有一段时间露出水面,钢筋焊接处极易锈蚀,导致框杆散落、结构破坏,严重影响了框架使用寿命和河道整治效果。
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.
透水框架采用杆件组合焊接工艺是指,透水框架由多根杆件组合焊接而成。透水框架焊接处形成尖角,对施工人员易造成作业伤害,安全风险较高;此外,杆件钢筋外露,易锈蚀、断裂,造成透水框架解体,影响岸坡护脚整体质量。拟限制使用,规定在大、中型水运工程中不得使用。
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.
