Concrete lifting pouring construction method for steel tube arch bridge arch ribs
The invention relates to a concrete lifting pouring construction method for steel tube arch bridge arch ribs. The method carries out concrete lifting pouring on the steel tube arch bridge arch ribs through conveying pump selecting, pouring hole arrangement, back pressure hole arrangement, steel tube cleaning, arch rib concrete blending, concrete pumping, discharging of concrete out of back pressure tubes, pumping stopping and concrete detection. Through construction processes and selection of the pouring concrete matching ratio, the self sealing performance and vibration-free performance of a steel tube arch are improved, and the strength of a bridge arch rib structure is increased.
