Pumping concrete pouring matching facilities and process method for ultra-deep impervious wall

Abstract

The application discloses a kind of pumping concrete pouring supporting facilities and process methods for ultra-deep impervious wall, including concrete pump truck, pouring pipe fittings and slurry pipe, the concrete pump truck is located in the side of slot, the discharge port of the concrete pump truck is connected with the top of the pouring pipe fittings, the bottom of both the pouring pipe fittings and the slurry pipe extends into the slot, the bottom of the slurry pipe is higher than the upper surface of concrete, and the slurry pipe is connected with back slurry assembly.The beneficial effect: the application has simple structure, reasonable design, simple process method, by pumping concrete to match flow limiting pouring guide pipe, the falling speed during concrete pouring can be reduced to reduce the adverse effects of concrete coarse and fine aggregate separation, mixed material segregation, etc., by active back slurry to reduce flocculation accumulation to reduce concrete and mud, flocculation mixed slurry, improve the quality of impervious wall.
