Sewage discharge treatment system and method for bridge cofferdam

Abstract

The invention discloses a sewage discharge treatment system and method for a bridge cofferdam, and relates to the field of bridge construction. The problem that in the bridge cofferdam construction process, discharged sewage is improperly treated, and the surrounding environment is polluted is solved. The system comprises a bridge cofferdam, a water-blocking isolation belt and a sewage treatment device, the water-blocking isolation belt is arranged on the outer side of the bridge cofferdam at intervals, the two ends of the water-blocking isolation belt are connected with river banks, and the water-blocking isolation belt, the bridge cofferdam and the river banks located between the water-blocking isolation belt and the bridge cofferdam jointly define a buffer area. The sewage treatment device is used for collecting sewage discharged by a bridge cofferdam and water flow infiltrated into surrounding water areas and purifying the sewage in a buffer area. The treatment method comprises the steps that the water blocking isolation belt is built on the outer side of the bridge cofferdam, the bridge cofferdam, the water blocking isolation belt and the river bank part located between the bridge cofferdam and the water blocking isolation belt jointly define a buffer area, sewage in the bridge cofferdam is discharged into the buffer area, and the sewage treatment device pumps the sewage in the buffer area and conducts purification treatment. The method is used for treating the sewage discharged in the bridge cofferdam construction process.

Description

Technical field[0001]The present invention relates to the field of bridge construction techniques, and in particular, to the sewage discharge processing system and method of bridge cofferdam.Background technique[0002]Bridge cofferdam engineering as an important part of the bridge infrastructure, has a pivotal role, existing bridge cofferdam has the following structural form: installed inspection gate to drain and repair, build two in front of the gate room The doorway is maintained in the gate, and the door is placed in the gate, and the door is placed in the door. It will serve as a water-water; two ends of the river block the water and soil dam camidamines, in the upper and lower rivers Segment appropriate position to Xiaoba Cuvet is drained; use the pulling steel door into the pulling steel door, the steel door is moved to the wing wall. When the pumping pump is activated, the water head is formed in the inside and outside when the drainage is larger than the amount of water. Dif...
