农村公路加宽改造过程中,新旧混凝土板块之间的连接是影响工程质量及进度的关键点,现有环氧树脂植筋和双面焊膨胀螺栓方案均存在实际操作难度大、质量不可控等不利因素。文章结合江苏省农村公路改造试点工程,优化了拉杆钢筋与膨胀螺栓的连接方式,方便了实际操作,保证了工程质量,同时也为其他混凝土路面加宽提供了借鉴方案。 During the widening and reconstruction of rural roads, the connection between the old and the new concrete slabs is the key point that affects the quality and progress of the project. Existing epoxy resin anchoring bars and double-sided welding expansion bolts are difficult to operate and of uncontrollable quality Unfavorable factors Combined with the pilot project of rural road reconstruction in Jiangsu Province, the article optimizes the connecting way between the rod bar and the expansion bolt, facilitates the practical operation and ensures the project quality, at the same time it also provides a reference scheme for other concrete pavement widening.
