The self-reset concrete frame comprises an expanding frame column, the expanding frame column is fixedly connectedto the side face of an existing frame column, and the expanding frame column and the existing frame column form a self-reset frame column; and hole channel through holes are formed in the expanding frame column in the height direction, prestressed bars are inserted and mounted in the hole channel through holes and are anchored at the upper end and the lower end of the expanding frame column. The implementation method comprises the steps that steel bars are arranged; the prestressed bars are arranged; pouring is conducted; the prestressed bars are tensioned; and grooving and grouting are conducted. The self-reset concrete frame for strengthening the existing column by enlarging the section and the implementation method of the self-reset concrete frame are used for building of the concrete frame.

Provided is an anti-retrograding speed bump. A left speed bump unit comprises a top plate and a bottom plate, wherein that top plate is semi-arc shaped, the left end of the top plate is fixedly connected with the left end of the bottom plate, and a support block inclined from the upper left to the lower right is arranged between the top plate and the bottom plate. A right speed bump unit comprisesan anti-retrograde steel sheet, a lower end of the anti-retrograde steel sheet is connected with a rotating bracket, a left end of the rotating bracket is connected with a tension spring, the other end of the tension spring is fixed on the bottom plate inside the left speed bump unit, and the right end of the rotating bracket is fixedly connected with a rotating shaft arranged along the length direction of the speed bump body. The anti-retrograde steel sheet is semi-arc shaped, and its left end extends into the top plate of the left speed bump unit. The right end of the anti-retrograde steelsheet is higher than the height of the right end of the top plate in the left speed bump unit. The stretching stroke of the tension spring shall not be less than the movement stroke of the right-handspeed bump unit bottom plate of the anti-retrograde steel sheet, which prevents retrograde traffic on a one-way lane and reduces traffic congestion.
