Description

Technical Field

[0001] The utility model relates to the technical field of expansion joints, in particular to an expansion joint leakage guide device. Background Art

[0002] "Deformation joints" usually refer to structural joints or joints in construction projects, also called expansion joints, which are designed to deal with structural deformation or displacement caused by thermal expansion and contraction, earthquakes and other factors in buildings. These joints can allow the building structure to move freely within a certain range, thereby reducing internal stress and protecting the integrity and safety of the building. In construction projects, the setting of deformation joints is a very important part, which can effectively prevent cracks and structural damage. At present, the expansion joint anti-seepage structure is mostly a simple rubber water-stop structure. Due to gradual aging and continuous impact of automobile loads, damage and even water leakage are increasing, which brings many inconveniences to urban management and citizens' travel, especially for urban road elevated bridges. The main manifestation is that the water flow on the bridge deck leaks through the expansion joints to the beams and piers, causing serious surface pollution and even corrosion of the bearing steel pads, further accelerating the aging of the bridge bearings. To this end, a leakage diversion device for expansion joints is proposed. Utility Model Content
