On October 23, 2025, BIC and Banglamark successfully held an online technical exchange meeting focused on flap gate technology. The meeting addressed key issues within the field, aiming to further optimize the flap gate design through in-depth communication and professional discussion, advance the finalization of the cooperation agreement between the two parties, and lay a solid foundation for the smooth execution of subsequent projects. Relevant technical leaders, project managers, and business representatives from both BIC and Banglamark attended the meeting, engaging in efficient and thorough discussions based on the meeting agenda.
The revision of the flap gate design drawings emerged as one of the key topics of the meeting, with the adjustment of the gate height being the core change within the design modifications. According to introductions from both technical teams, and to better meet the requirements for protection height, passage efficiency, and safety in practical application scenarios, it was decided, after several rounds of prior technical demonstration, to increase the flap gate height from the original 3 meters to 3.5 meters. This adjustment in gate height triggered a chain reaction of design changes to the base structure of the flap gate bottom slab. Technicians explained in detail during the meeting that the gate height, as a critical parameter of the flap gate, directly affects the force state of the hydraulic cylinder. The hydraulic cylinder, being the key driving component for the flap gate's operation, has its stability and reasonableness of force bearing crucial to the equipment's service life and operational safety. Under different gate height conditions, to ensure the hydraulic cylinder remains in its optimal force state and avoid issues such as component wear and increased failure risk due to uneven force distribution, the position of the cylinder's fulcrum point must be precisely adjusted. From the structural perspective of the bottom slab, the change in the fulcrum position directly translates to an alteration in the step height of the bottom slab. Consequently, the dimensions, angle, and connection method of the bottom slab step need to be redesigned to ensure it can provide stable and reliable support for the hydraulic cylinder while perfectly adapting to other components of the flap gate, thereby guaranteeing the overall structural stability and operational coordination of the equipment.
The successful holding of this online technical exchange meeting not only effectively addressed critical technical issues currently faced in the collaboration but also clarified the direction for flap gate design optimization. Furthermore, it enhanced mutual trust and consensus on cooperation at the technical level. Both parties expressed that they would take this meeting as a new starting point to accelerate follow-up work such as agreement finalization, design refinement, and manufacturing, ensuring the smooth progress of the flap gate project. They aim to jointly create high-quality, high-performance flap gate products, providing superior equipment support for safety management and passage security in relevant industries, ultimately achieving mutual benefits and sustainable development.
