Integral door frame structure of built-in reverse jacking type hydraulic oil cylinder well

The utility model relates to an integral door frame structure of a built-in reverse jacking type hydraulic oil cylinder well, which belongs to the technical field of integral door frame structures of water gates, and comprises two side pier door grooves which are symmetrical to each other; the number of the middle pier gate grooves is one less than the number of the gate holes, and the middle pier gate grooves are mutually symmetrical; the number of the bottom sills is the same as the number of the lintels and the number of the gate holes, and the side pier gate grooves and the middle pier gate grooves are fixedly connected with the bottom sills; the main reverse rails of the gate grooves are integrated into a whole, the gate grooves of the adjacent flow channels are also integrated into a whole, and the hydraulic opening and closing devices are arranged in the gate grooves, so that the integral performance is good, the door frame mounting process can be effectively simplified, the door frame hoisting frequen
