The above situation used to make many units confused, spending a lot of money on maintenance and repair. But now, with the initiative "Canopy for access to the air defense battlefield" researched and manufactured by Captain Dao Trung Thanh, Assistant of the barracks (Logistics-Technical Department, Thanh Hoa Provincial Military Command) and his colleagues, the above shortcomings have been completely overcome.

3D simulation of the initiative "Air defense shelter".

Through a 3D simulation video , Captain Dao Trung Thanh introduced: "The roof of the entrance to the air defense position" was designed by us, with reasonable drainage adjustment, and a steel roof system manually controlled by a crank, gear, and guide rail system, ensuring waterproofing and convenience during combat maneuvers."

Studying the structure of the initiative, we found that the entrance to the battlefield is designed with a corrugated iron roof, surrounded by flat iron. When rotating the rotating shaft (located at the first step of the ladder), the roof frame can slide open and close on the guide rail with stainless gears. The materials for the roof construction are all available on the market such as galvanized square steel, sliding wheels for sliding gates, steel guide rails, corrugated iron, straight iron and accompanying accessories such as storm brackets, locking pins, bolts, etc.

Captain Dao Trung Thanh, representing the group of authors of the initiative "Canopy for the entrance to the air defense position", received the 25th Creative Youth Award in the Army.

This initiative has created a mobile roof, preventing rainwater from splashing into the construction; protecting the structures from the effects of weather; convenient to use, ensuring mobility when needed. According to the load calculation when the roof is closed, it can withstand storms and not be blown off. The initiative "Roof for the entrance to the air defense position" has just won third prize at the 25th Youth Creative Award in the Army.

Colonel Tran Quoc Can, Head of the Barracks Department, Logistics and Engineering Department of Military Region 4, emphasized: “The initiative contributes to increasing the usability of the project, making it convenient to use and maintain; has high load-bearing capacity and does not affect the mobility of troops when situations arise. Moreover, the initiative is highly applicable and can be applied to command buildings with similar structures in military units.”
