Bridge deck pavement comprehensive drainage preventing and water guiding method
The invention discloses a bridge deck pavement comprehensive drainage preventing and water guiding method, and belongs to the field of bridge engineering. The method comprises the steps that a longitudinal drainage blind ditch is formed in a bridge deck waterproof layer, is arranged at the bottom of a transverse slope of a bridge deck and is connected with a water drainage hole; a transverse drainage seepage ditch is formed in the bridge deck waterproof layer, is parallel to the expansion joint and is communicated with the water drainage hole in the longitudinal slope toe; a high-water-conductivity water guide and drainage pipe is arranged at a bridge deck expansion joint and filled with quick-hardening high-strength cement mortar. Compared with the prior art, the comprehensive drainage preventing and water guiding method for bridge deck pavement can solve the technical problems of frequent water pumping, icing and frost heaving damage at the expansion joint and difficulty in quick repair, and has good popularization and application values.
本发明公开了一种桥面铺装综合防排导水方法，属于桥梁工程领域。该方法包括：在桥面防水层上设置纵向排水盲沟，所述纵向排水盲沟设置在桥面横向坡坡底处，与泄水孔相连；在桥面防水层上设置横向排水渗沟，所述横向排水渗沟与伸缩缝平行设置，并与纵坡坡脚处的泄水孔相通；在桥面伸缩缝处设置高导水型导排水管，并以快硬性高强水泥砂浆进行填充。与现有技术相比，本发明的桥面铺装综合防排导水方法能够解决伸缩缝处唧水、结冰现象及冻胀破损问题频发和难以快速修复的技术难题，具有很好的推广应用价值。
