Prefabricated buttressed retaining wall assembling structure and construction method

Abstract

The invention discloses a prefabricated buttressed retaining wall assembling structure and a construction method. The prefabricated buttressed retaining wall assembling structure comprises a pluralityof prefabricated bottom plates, a plurality of prefabricated vertical walls, and a plurality of prefabricated buttressed plates; vertical wall slotted holes and buttressed slotted holes are formed inthe prefabricated bottom plates and correspond to the prefabricated vertical walls and the prefabricated buttressed slotted holes respectively; every two prefabricated vertical walls are formed by assembling a groove structure and a protruding structure; a plurality of vertical wall tenons are arranged under the prefabricated vertical walls; a plurality of pairs of annular closed steel bars matched with one another are embedded at the positions where the prefabricated vertical walls and the corresponding prefabricated buttressed plates are assembled; and the lower parts of each prefabricatedvertical wall and the corresponding prefabricated buttressed plate are connected with the corresponding prefabricated bottom plates. The construction method comprises the following steps that during construction, at first, a leveling layer is manufactured, then the prefabricated bottom plates are hoisted, the prefabricated vertical walls and prefabricated buttressed plates are installed on the prefabricated bottom plates, and finally, longitudinal steel bars are inserted into the annular closed steel bars that overlap between the precast vertical walls and prefabricated buttressed plates, andare cast with high-strength non-shrinkage concrete. The prefabrication of a relatively high buttressed retaining wall filled with soil can be realized, and the construction speed is increased.

Description

technical field [0001] The invention relates to the technical field of retaining wall construction, in particular to a prefabricated buttress-type retaining wall assembly structure and a construction method. Background technique [0002] In the prior art, the road retaining wall is mostly constructed by the cast-in-place method. With the development of society, cast-in-place retaining walls gradually cannot meet people's requirements for fast, low-interference construction and civilized construction. [0003] In recent years, prefabricated retaining walls have been used in bridge construction. In practical application, there have been engineering practices of prefabricated U-shaped retaining walls and prefabricated L-shaped retaining walls, but the retaining walls with high filling height and buttresses are still mainly cast-in-place. [0004] Therefore, how to use prefabrication to realize the construction of a retaining wall with a relatively high height and provided wit...
