Pouring bubble prevention construction technology for highway engineering bridge pouring
The invention discloses a pouring bubble prevention construction technology for highway engineering bridge pouring. The pouring bubble prevention construction technology comprises the following steps that S1, hanging basket formworks are spliced; S2, beam body pouring; S3, concrete curing; S4, beam body prestress tensioning and grouting operation; and S5, the hanging basket moves forwards, the installed hanging basket moves forwards, and the project of the next bridge section continues to be completed. According to the pouring bubble prevention construction technology for highway engineering bridge pouring, the pouring bubble prevention device is more stable in placement, can rotate according to needs, and is more convenient to use; and after a concrete pump truck transports concrete to a construction site, the temperature and workability of the concrete need to be tested, concrete bricks need to be manufactured, the strength of the concrete needs to be detected, and the quality of the concrete is ensured, in S204, the poured concrete layer is vibrated in a layered mode through a pouring anti-bubble device, each point is vibrated for 20-30 seconds, bubbles in the concrete can completely disappear, concrete bubbles, fragmentation and the like are prevented, and the engineering quality is improved.
本发明公开了一种公路工程桥梁浇注用防浇注气泡的施工工艺，包括以下步骤：S1：挂篮模板拼装；S2：梁体浇注；S3：养护混凝土；S4：梁体预应力张拉，压浆作业；S5：挂篮前移，将已安装好的挂篮向前移动，继续完成下一桥梁段的工程；本发明的公路工程桥梁浇注用防浇注气泡的施工工艺，涉及到的浇注防气泡装置，放置更加稳定，可以根据需要转动方向，使用更加便捷；混凝土泵车将混泥土运输至工地后需要测试混凝土的温度、和宜性，制作混凝土砖检测混凝土的强度，确保混凝土品质，S204振捣混凝土使用浇注防气泡装置对浇灌好的混凝土层进行分层振捣，每点振捣20至30秒，能够使混凝土中的气泡完全消失，防止混凝土气泡，碎裂等情况发生，提高工程质量。
