Ultrahigh pile supporting box type reinforced concrete retaining wall and construction method thereof
The invention discloses an ultrahigh pile supporting box type reinforced concrete retaining wall and a construction method.The retaining wall comprises a pile foundation and a wall body, the wall body comprises a bottom plate, a wall plate, a buttress and an unloading plate, a drainage pipeline structure is laid in the wall body, the bottom plate is horizontally arranged at the top of the pile foundation, the wall plate is vertically arranged on the bottom plate, and the unloading plate is arranged on the wall body; the unloading plates are vertically arranged on the front side of the wallboard at intervals, one end of each unloading plate is fixed to the wallboard, the other end of each unloading plate horizontally extends forwards, and the buttresses are vertically arranged between the wallboard and the unloading plates at intervals. According to the retaining wall structure, the advantage of high bearing capacity of the pile foundation and the unloading effect of the double-layer unloading plate in the upper box-type structure are utilized; the problems that in the prior art, due to the fact that lateral soil pressure behind an ultrahigh retaining wall is too large, the retaining wall foundation bearing capacity is insufficient, the wall top deformation is too large, the retaining wall size is too large, the foundation burial depth is too large, and the anti-overturning and anti-sliding stability is insufficient can be effectively solved. The retaining wall structure can be suitable for high and steep fill slopes with the height being 15 m or above under different geological conditions.
本发明公开了一种超高桩托箱式钢筋混凝土挡土墙及施工方法，挡土墙包括桩基础及墙主体，墙主体包括底板、墙板、扶壁和卸荷板，墙主体内铺设有排水管道结构，底板水平设于桩基础的顶部，墙板竖立于底板上，若干卸荷板上下间隔设于墙板的前侧，卸荷板一端固定于墙板上，另一端水平向前伸出，若干扶壁间隔竖立于墙板与卸荷板之间。本挡土墙结构借助桩基础的高承载力优势以及上部箱式结构中双层卸荷板的卸荷作用，可有效解决现有技术面临的超高挡土墙墙后过大侧向土压力导致的挡墙地基承载力不足、墙顶变形过大、挡土墙尺寸过大、基础埋深过大、抗倾覆及抗滑移稳定性不足等问题，使得挡土墙结构可适用于不同地质情况下、高度15m以上的高陡填方边坡。
