A. Investigation of the actual use of capsules Under the guidance of the great strategic principle of the great leader, Chairman Mao, “grasping the revolution, promoting production, promoting work, and preparing for war”, the majority of employees of our factory have been self-reliant, hard-working, and bold. The revolutionary spirit was successfully trial-produced in 1969 to create “inflatable soft molds” for pre-stressed reinforced concrete hollow piles (referred to as “capsules” and “flexible molds abroad”). First, it was applied in the Engineering Department of the First Navigation Engineering Bureau of the Ministry of Communications and the Concrete Prefabricated Factory of the Third Navigation Engineering Bureau, and successfully cast hollow piles and other hollow members. The emergence of capsules in the field of concrete component manufacturing in China is a new thing, which has changed the status quo of rigid templates that have been used since the existing concrete. The capsule is made of adhesive tape and the tape is made of one layer or
