Pouring process for preventing steel pipe concrete from disengaging
The invention discloses a pouring process for preventing steel pipe concrete from disengaging, which comprises the following steps: heating a steel tube to expand the steel tube, and pouring concreteinto the steel tube; and after concrete pouring is completed, stopping heating, and sealing the surface of the poured concrete, so that the steel pipe and the concrete shrink together, and the solidified concrete is hooped. In the pouring process for preventing steel pipe concrete from disengaging, the steel pipe is heated first, concrete is poured into the steel pipe after the steel pipe is expanded; thus, after pouring is completed and heating is stopped, the steel pipe and the concrete shrink together, thus, after the steel pipe is cooled and the concrete is solidified, the steel pipe and the concrete can form a hooped combined structure in the construction stage, and the steel pipe and the concrete cannot be thermally separated under the action of sunlight in the use stage, so that theservice life of a concrete-filled steel tube member is prolonged, and the concrete-filled steel tube arch bridge can be applied to a larger span.
本发明公开了一种防钢管混凝土脱空的灌注工艺，加热钢管，使钢管发生热膨胀后，再向钢管内灌注混凝土；混凝土灌注完成后停止加热并密封已灌注完成的混凝土表面，使钢管与混凝土一同收缩并箍紧凝固后的混凝土。本发明的防钢管混凝土脱空的灌注工艺，通过先对钢管加热，使其膨胀后再向钢管内灌注混凝土，如此，灌注完成且停止加热后，钢管与混凝土一同收缩，如此，在钢管冷却后和在混凝土凝固后，能够实现在施工阶段使钢管与混凝土形成箍紧的组合结构，并且使其在使用阶段日照作用下，两者不会发生热脱空，进而延长钢管混凝土构件的使用年限，使钢管混凝土拱桥能够实现更大跨径的应用。
