Drainage device for highway bridge
The invention discloses a drainage device for a highway bridge, and belongs to the technical field of highway bridges, the drainage device comprises main beams and telescopic pipe fittings arranged between two adjacent main beams, longitudinal drainage holes are formed in the main beams, and the telescopic pipe fittings are communicated with the longitudinal drainage holes; each telescopic pipe fitting comprises a hard straight pipe and two corrugated pipes coaxially arranged at the two ends of the hard straight pipe, connecting discs connected with the main beam are arranged at the outer ends of the corrugated pipes, a plurality of sets of telescopic dampers are arranged between the two connecting discs of the same telescopic pipe fitting, and the telescopic dampers are annularly and evenly distributed on the outer circumference of the telescopic pipe fitting; a middle support is arranged on the outer side of the hard straight pipe, a guide rod is fixedly arranged on the middle support, and the two ends of the guide rod extend in the longitudinal direction of the main beam. When the device encounters the effect of expansion caused by heat and contraction caused by cold of a bridge or the influence of natural disasters, the drainage device body can be effectively protected against damage, the service life of the device is prolonged, and normal drainage of the device is guaranteed.
本发明公开了一种公路桥梁用排水装置，属于公路桥梁技术领域，包括主梁、设置在相邻两主梁之间的伸缩管件，主梁上开设有纵向排水孔，伸缩管件与纵向排水孔连通；伸缩管件包括硬直管、同轴设置在硬直管两端的两根波纹管，波纹管的外端设置有与主梁连接的连接盘，同一伸缩管件的两个连接盘之间设置有若干组伸缩阻尼器，伸缩阻尼器环形均布在伸缩管件的外圆周；硬直管的外侧设置有中间支座，中间支座上固定设置有导杆，导杆的两端沿主梁的纵向延伸。本发明装置在遇到桥梁自身热胀冷缩的作用或者自然灾害的影响时，可以有效保护排水装置主体不受破坏，提高装置的寿命，保证装置正常排水。
