Problems solved by technology
At present, the prefabricated retaining wall used in the national standard atlas has its upper structure (panels and ribs) prefabricated in factories, but the floor structure is still constructed on site. This method of prefabricating the upper structure is more troublesome and the transportation efficiency is not high. (with ribs), the prefabrication rate is low, the maintenance time is long, and the on-site operation is relatively complicated

A novel prefabricated cantilever retaining wall formed by assembly is provided. A prefabricated bottom plate is provided with a clamping groove and a tenon, and a prefabricated panel is provided witha lower portion matched with the clamping groove. Moreover, embedded connecting bolts are arranged in the prefabricated bottom plate, and reserved holes matched with the embedded connecting bolts areformed in the prefabricated panel. After the prefabricated bottom plate is hoisted in place, the prefabricated panel is hoisted to enable the lower portion of the panel to be exactly inserted into theclamping groove of the bottom plate. The embedded connecting bolts of the prefabricated bottom plate penetrate through the reserved holes of the prefabricated panel, and the panel and the bottom plate are connected into an integral structure through connecting nuts. According to the prefabricated cantilever retaining wall in the form, factory prefabrication, transportation and field installationare facilitated, the workload of field steel bar binding and concrete pouring is reduced to the maximum extent, the concrete curing time is shortened to the maximum extent, and the construction periodof the retaining wall is effectively shortened. The strength and stability of wall connection can be guaranteed, the connection is reliable, the structure is simple, and construction is convenient. The connecting quality of the prefabricated parts is easily guaranteed, and good popularization value is achieved.
Description
technical field [0001] The invention relates to the technical field of road engineering prefabrication and assembly, in particular to a prefabricated cantilever retaining wall connected in a combined manner. Background technique [0002] Conventional cantilever retaining walls are basically cast-in-place, but the concrete strength of the wall is low and the amount of reinforcement is high; the amount of formwork is large, the turnover rate is low, and the construction efficiency is low; the construction site requires a lot of labor and labor costs; the process Complexity, slow construction speed, on-site maintenance and other issues. [0003] The conventional cantilever retaining wall adopts a section of 10m, the shape of the section is "L-shaped", the length is 10m, the width of the bottom plate is 4~5m, the height is 2~5m, and the maximum weight is 80 tons. If it is prefabricated in a factory and installed on site, Factory prefabrication is difficult, and transportation r...
