Whole-set balance weight type embankment retaining wall reinforcing structure and reinforcing method
The invention is applicable to the field of side slope retaining, and provides a complete balance weight type embankment retaining wall reinforcing structure and a reinforcing method, and the reinforcing structure is mainly composed of a wall back rock-soil body reinforcing structure, a wall body reinforcing and repairing structure and an externally-pasted surface protecting wall structure. The wall back is pre-reinforced by adopting a vertical micro steel pipe and a mode of in-pipe permeation grouting, so that the property of a rock-soil body behind the wall is improved, the stability of the wall body in the reinforcing construction period is improved, and the traffic safety of vehicles on the existing road is ensured. The cast-in-place reinforced concrete surface protecting wall is used for preventing the existing wall blocking surface layer from being disengaged and preventing bulging rubbles from falling off; the vertical miniature steel pipes are arranged in the wall and can be connected with the toe of the existing retaining wall in a reinforced mode, and the overall anti-sliding performance of the wall body is further improved. The wall body is reinforced and reinforced in a manner of arranging inclined micro steel pipes in post-pouring holes and performing permeation grouting in the pipes; the steel pipes and the face protecting wall reinforcing mesh are welded into a whole through the L-shaped connecting ribs, and the face protecting wall is prevented from falling off and being separated from the wall body of the existing retaining wall.
本发明适用于边坡支挡领域，提供了一种成套式衡重式路堤挡墙加固结构及加固方法，加固结构主要由墙背岩土体加固结构、墙身补强修复结构和外贴护面墙结构三大部分组成。墙背采用竖向微型钢管和管内渗透注浆的方式进行预加固，改善墙后岩土体性质，提高墙身补强施工期间稳定性，确保既有道路车辆通行安全。现浇钢筋砼护面墙，防止既有挡墙面层脱空和鼓胀的片石掉落；墙内设置竖向微型钢管，可以与既有挡墙墙趾加强连接，进一步提高墙体的整体抗滑性能。墙身利用后浇孔设置斜向微型钢管和管内渗透注浆的方式进行补强和加固；通过L型连接筋将钢管与护面墙钢筋网焊接成整体，防止护面墙与既有挡墙墙身脱落与分离。
