Assembly type finished open trench without welding

The utility model discloses an assembly type finished open trench without welding. The assembly type finished open trench without welding comprises open trench assemblies and connecting buckles. The open trench assemblies comprise the stainless steel finished open trench assemblies (1) and the water discharging integrated open trench assembly (6). The stainless steel finished open trench assemblies (1) are connected into a whole through the connecting buckles and are connected with the water discharging integrated open trench assembly (6) into a whole through the connecting buckles. The edges of the stainless steel finished open trench assembles (1) and the edges of the water discharging integrated open trench assembly (6) are bent so that U-shaped open trench assembly bending portions can be formed; the connecting buckles are of a plate shape and the two lateral sides used for buckling of each connecting buckle are bent to form a U-shaped buckle bending portion; each open trench assembly bending portion is oppositely buckled with the corresponding buckle bending portion and a seepage-proof rubber mat (4) is arranged between each open trench assembly bending portion and the corresponding buckle bending portion. The assembly type finished open trench without welding is good in waterproof effect, free of water leakage after long time use, beneficial to cleaning and capable of being prevented from being blocked by sundries falling into the trench.
