The invention relates to the technical field of engineering construction, in particular to a multiple-joint linkage type integrated formwork surrounding a wet connection section and a method. The integrated formwork comprises a formwork body and rotating shafts. The formwork body is composed of a first side surface formwork body, a second side surface formwork body and a bottom surface formwork body, the first side surface formwork body and the second side surface formwork body are connected to the bottom surface formwork body through the rotating shafts, the first side surface formwork body, the second side surface formwork body and the bottom surface formwork body can rotate around the rotating shafts, suspended locking fasteners are arranged on the top of the first side surface formwork body and the top of the second side surface formwork body respectively, and slide wheels are arranged in the suspended locking fasteners and slide along slide rails on the tops of a middle cross beam and a collar beam. According to the invention, the formwork is divided into three planes, every two planes are connected through the foldable rotating shafts shaped like hinges so that the formwork bodies can rotate around the rotating shafts, the formwork has the effect of surrounding the wet connection section, assembly and disassembly of the formwork are convenient, the quality is controllable, and circulation is convenient.
