A shoulder slab is installed on the shoulder portion between the ditch and the road surface for hardening, with the outer edge of the shoulder slab connected to the sidewall of the ditch. Slipform construction is widely used in shoulder slab construction due to its ease of construction, high efficiency, and strong environmental adaptability of cast-in-place structures. During highway pavement renovation, the shoulder slab typically needs to be removed for renovation. Due to construction errors in the old roadside ditch and deformation of the ditch during use, the elevation, width, and slope of the intersection of the shoulder slab and the ditch vary irregularly, resulting in an uneven line shape. The original slipform molds of fixed size and shape suffer from problems such as jamming or leakage, making them unsuitable for shoulder slab renovation. Utility Model Content
