The invention discloses a manufacturing method for a demolition-free textile fiber web reinforced concrete formwork and relates to a formwork member with general applications. The manufacturing method comprises the following steps of: determining the size of the formwork and erecting the formwork; preparing a textile glass fiber web; preparing a concrete material; determining the mass mixing ratio of the concrete material; mixing the concrete; casting a first layer of concrete; paving the textile glass fiber web; and finishing the casting, curing and demolishment of the concrete. The formwork manufactured by the manufacturing method disclosed by the invention is manufactured by compounding self-compaction fine aggregate concrete with high flowability as a matrix with the alkali-resistant textile glass fiber web; and the formwork is not needed to be demolished after being used, so that the defects of no environment-friendly characteristic, high price, low construction efficiency and high possibilities that a reinforcing bar is inaccurate in positioning and the surface of the member is not flat after the formwork is demolished in a traditional wood formwork, a bamboo plywood formwork or a steel formwork are overcome.
