Traffic relief method for sunken square under high fall condition
The invention relates to the technical field of transportation junction construction, in particular to a traffic relief method for a sunken square under the high-fall condition. Comprising the following steps of determining a foundation pit excavation method and division of labor of all areas, completing construction of a defibered side diaphragm wall and a steel pipe column, slope excavation, diaphragm wall base surface treatment and cushion layer pouring, construction of a defibered section structure cover plate, construction of a retaining wall on a top plate, repeating the steps to complete construction of multiple sections of top plates, backfilling a roadbed and constructing a fence. According to the construction method, the traffic relief road is constructed by covering and excavating the top plates, the high-fall section is excavated in a sloping mode at the interval of one cross beam with the span being 1: 1, connectors are preset between the top plates of all the sections for synchronous construction, and the retaining wall is arranged to support soil pressure of the backfill roadbed of the low-terrain sinking square section; traffic relief is completed in a construction site, the construction quality is improved, and the construction safety is guaranteed.
本发明涉及交通枢纽建设技术领域，具体是一种高落差条件下带下沉广场的交通疏解方法，包括以下步骤：确定基坑开挖方法及各区域分工、完成疏解侧地连墙及钢管柱施工、放坡开挖、地连墙基面处理及垫层浇筑、疏解段结构盖板施工、顶板上挡土墙施工、重复以上步骤完成多段顶板施工、回填路基与施工围挡，本申请通过盖挖顶板施作交通疏解路，高落差地段间隔一个横梁跨度1：1放坡开挖，各段顶板间预设接驳器同步进行施工，通过设置挡土墙支撑低地势下沉广场段回填路基的土压，在不占用原有交通道路的基础上，在施工场地内完成了交通疏解，提高了施工质量，保证了施工安全。
