Construction method of interlocking self-embedded building block retaining wall revetment
The invention relates to a construction method of an interlocking self-embedded building block retaining wall revetment. The construction method comprises the steps of plain concrete bottom plate construction, first batch building block building, geogrid and geotextile laying, building block circulating building block building, concrete building block coping beam pouring, drainage ditch construction and road surface pouring. The retaining wall has the beneficial effects that the temporary safety protection guide frame externally fixed to the plain concrete bottom plate is adopted, the guide frame can be flexibly adjusted, accurate positioning of each structural layer block is achieved, and the overall gradient of the retaining wall is guaranteed; when the geogrid is laid between the backfill soil layers behind the wall, the geogrid tensioner is used for conducting auxiliary tensioning on the geogrid, and the problems of displacement, edge curling and the like of the geogrid after being laid before backfill and in the backfill process are prevented; the building block coping Z-shaped side molds with variable cross sections on the inner side and the outer side are adopted, and the building block coping Z-shaped side molds on the inner side and the outer side are designed according to the gradient of the retaining wall and completely attached to the built building block retaining wall, so that the pouring quality of coping beam concrete is effectively improved.
本发明涉及一种互锁自嵌式砌块挡墙护岸施工方法，包括步骤：素混凝土底板施工、首批砌块垒筑、土工格栅及土工布铺设、砌块循环垒筑、浇筑混凝土砌块压顶梁、排水沟施工和路面浇筑。本发明的有益效果是：采用外置固定于素混凝土底板的临时安全防护导向架，导向架可灵活调整，实现每一结构层切块的精确定位，保证挡墙整体梯度；在墙后回填土层间铺设土工格栅时，采用土工格栅张紧器对土工格栅进行辅助张拉，防止土工格栅铺设后在回填之前及回填过程中出现位移、卷边等问题；采用内外侧变截面的砌块压顶Z形侧模，内外侧的砌块压顶Z形侧模分别根据挡墙梯度设计，与已砌筑砌块挡墙完全贴合，有效提升压顶梁混凝土的浇筑质量。
