The invention relates to a prefabricated retaining wall which comprises a plurality of layers of prefabricated blocks and steel bars. The prefabricated blocks and the steel bars are arranged in an up-down staggered lap joint manner, each prefabricated block comprises a prefabricated middle block and prefabricated edge blocks which are spliced with each other, cross-shaped protrusions are arrangedon the top faces of the prefabricated middle blocks, and square protrusions are arranged on the bottom faces of the prefabricated middle blocks; the four sides of the square protrusions are shorter than the four sides of the prefabricated middle blocks to form bottom face grooves, semicircular drain holes are formed in the side edges of the prefabricated middle blocks, the top faces of the prefabricated middle blocks are each divided into four square faces through the cross-shaped protrusions, a steel bar hole is vertically formed in each square face, and the steel bar holes penetrate throughthe bottom faces of the prefabricated middle blocks; and the structures of the prefabricated edge blocks are the same as those of the prefabricated middle blocks which are longitudinally sectioned. According to the prefabricated retaining wall, various problems of the retaining wall for traffic reconciliation during subway construction can be solved, the practicability of the retaining wall is improved, and application and popularization during subway construction are facilitated.
本发明涉及一种预制装配式挡土墙，包括若干层上下错缝搭接布置的预制块和钢筋，所述预制块包括相互拼接的预制中块和预制边块，所述预制中块的顶面设有十字凸起，预制中块的底面设有方形凸起，方形凸起的四边短于预制中块的四边从而形成底面凹槽，预制中块的侧边设有半圆形泄水孔，十字凸起将预制中块的顶面分隔出的四个方形面，每个方形面上竖直设置钢筋孔，钢筋孔贯通至预制中块的底面；所述预制边块的结构与纵向剖切后的预制中块相同。本发明可以解决地铁施工期间用于交通疏解的挡土墙存在的各种问题，提高了挡土墙的实用性，有利于在地铁施工期间推广使用。
