Load reduction and heightening structure of existing retaining wall and construction method of load reduction and heightening structure
The invention discloses a load reduction and heightening structure of an existing retaining wall and a construction method of the load reduction and heightening structure. Driving construction of a lead hole type prefabricated plate pile is carried out at the horizontal clear distance position away from the back of the existing retaining wall by 1/3 of the height, a basic trough is dug on the upper portion of the space between the existing retaining wall and the prefabricated plate pile, a reinforcing layer is arranged at the bottom of the basic trough, a support is arranged on the reinforcinglayer in a hoisting manner, and a top plate is placed on the support. An expansion foundation is additionally arranged on the outer side of an original foundation of the existing retaining wall, transverse connecting bars are used for connecting, an extending wall toe is arranged on the outer side of the expansion foundation, a ribbed plate is additionally arranged on the upper portion, transverse connecting bars are arranged at the bottoms of the rubbed plate and the existing retaining wall, a heightening retaining wall is arranged at the top of the existing retaining wall through vertical connecting bars, an ultralong unloading plate is arranged in the middle of the heightening retaining wall, water drainage holes are formed in the upper portion and the lower portion of the ultralong unloading plate of the heightening retaining wall in sequence, finally, a water filter layer and artificial filling soil are sequentially arranged on the back of the heightening retaining wall, face layers are arranged at the tops of the water filter layer and the artificial filling soil, and the height of the tops of the face layer is consistent with the height of the top of the heightening retaining wall.
本发明提供一种既有挡墙的减载加高结构及其施工方法，在距离既有挡墙背部三分之一高度的水平净距处，进行引孔式预制板桩的打设施工，在既有挡墙和预制板桩之间的上部挖掘基槽，在基槽底设置加固层并在加固层上吊放设置支架，顶板放置于支架上，在既有挡墙的原有基础外侧增设拓展基础，通过横向连接筋进行连接，拓展基础外侧设有延伸墙趾，上部加设肋板，肋板与既有挡墙底部设置横向连接筋，加高挡墙通过竖向连接筋设置在既有挡墙的顶部，在加高挡墙中部设置超长卸载板，在加高挡墙的超长卸载板上下方依次设置好泄水孔，最后在加高挡墙背后依次设置滤水层和人工填土，并在滤水层和人工填土顶部设置面层，面层顶部与加高挡墙顶部高度一致。
