| description | The invention provides a pile bottom leveling and filling strength forming method for a prefabricated assembly type pipe pile. The pile bottom leveling and filling strength forming method comprises the following steps of (1) assembling a prefabricated tubular pile on site, lowering the prefabricated tubular pile to a certain distance away from the bottom of a hole, and temporarily fixing the prefabricated tubular pile through a hoop; (2) cleaning sediments at the bottom of the hole through slurry circulation; (3) after cleaning is completed, blending cement-mixed soil, and continuing to perform reverse circulation through the cement-mixed soil; (4) pouring underwater concrete; (5) loosening the hoop is, and grouting the pipe pile in place; (6) finely adjusting the verticality of the pipe pile; (7) performing maintaining. By means of the method, the pile bottom of the prefabricated pipe pile of a fabricated bridge can be horizontal, and besides, pile bottom strength and pile periphery strength meet the require |
