工程上常见的挡土墙其施工顺序都是先基础,后上部,自下而上进行施工,而后在墙背面回填土。“倒作法”挡土墙与一般挡土墙施工顺序不同之处在于:它是自上而下进行施工的。可用于基础开挖中边坡的临时或永久性支护,对因场地条件限制,边坡及挡土墙都必须直立时,具有较大的使用价值。下面就具体工程实例对其设计方法和施工要求进行介绍。
The common construction of the retaining wall in the project is based on the construction sequence, the upper part of the retaining wall and the construction from the bottom to the top, and then backfill the soil on the back of the wall. The difference between the construction sequence of the “reverse practice” retaining wall and the general retaining wall is that it is constructed from the top down. It can be used for the temporary or permanent support of the slope in the foundation excavation, and has great use value when the slope and the retaining wall must stand erect due to site conditions. The following describes the design method and construction requirements for specific project examples.
