Short-term and long-term connection retaining wall construction method

According to the short-term and long-term connection retaining wall construction method provided by the invention, by performing reservation design in the structure of the short-term retaining wall, excavation of a new foundation during long-term implementation can be avoided, so that traffic influence and potential safety hazards during long-term implementation are eliminated. The method comprises the steps that when a recent retaining wall is manufactured, a bottom foundation and part of a wall body of a long-term retaining wall are excavated and poured in advance and can be directly used during long-term widening, and the retaining wall foundation is prevented from being excavated again. 本发明提供了一种近远期衔接挡墙构造方法，其通过在近期挡墙的结构中进行预留设计，可避免远期实施时开挖新建基础，从而消除远期实施时的交通影响和安全隐患。其包括：在近期挡墙的制作时，提前开挖浇筑远期挡墙的底部基础及部分墙身，可供远期拼宽时直接使用，避免重新开挖挡墙基础。
