More Information
Summary:The invention discloses a frame beam lattice bridge structure for crossing an underground pipeline and a construction method of the frame beam lattice bridge structure. The structure comprises an upper structure and a lower structure, wherein the upper structure comprises longitudinal beams, cross beams and brick blank film backfill grids; the lower structure is composed of a light bridge abutment and a cast-in-situ bored pile foundation, road surface loads are effectively transmitted to the foundation through a formed frame beam lattice structure, and safe operation of crossing underground pipelines is guaranteed. The main construction method comprises the steps of surface cleaning excavation, pile foundation construction through a cast-in-situ bored method, pile head breaking and flattening, concrete cushion layer pouring within the range of a beam body, brick moulding bed building, steel bar installation, concrete pouring, curing and the like. Compared with an existing concrete protective cover plate struc
