Background technique

At present, in the domestic construction field, building structures such as hydraulic structures, harbor and sea structures, bridges and culverts and tunnels usually use wooden formwork, steel formwork and other formwork, which has disadvantages such as large consumption, inconvenient disassembly and assembly, high turnover cost, and low utilization rate. In the traditional structure, the ordinary concrete surface is naturally exposed, and its durability is low. At the same time, designing with crack resistance as the control condition is an important feature that distinguishes hydraulic structures and other types of building structures. The problem of easy cracking of ordinary concrete will not only affect the normal work of hydraulic structures, but also affect their durability and performance. Seriously, it may even affect the safe operation of the structure. The above points have always been difficult problems to solve in the construction and use of hydraulic structures, harbor and sea structures, bridges, culverts and tunnels. The problems referred to above can be effectively solved by utilizing the crack-proof and seepage-proof permanent formwork that can be assembled, but the manufacturing mold of the crack-proof and seepage-proof permanent formwork that can be assembled has not been reported yet.
