Prestress bunching assembly type open caisson construction method
A pre-stressed bunching assembly type open caisson construction method comprises the following steps that a, a plurality of hollow prefabricated parts are inserted along the periphery of a to-be-excavated area of an open caisson, a closed rectangular supporting structure is defined by the multiple prefabricated parts, and the prefabricated parts comprise working section prefabricated parts and standard section prefabricated parts; the working section prefabricated parts are located at the four corners of a to-be-excavated area of the open caisson, and the standard section prefabricated parts are located between every two adjacent working section prefabricated parts in the circumferential direction; b, a steel strand penetrates through the position between every two adjacent working section prefabricated parts in the circumferential direction and is tensioned, and the steel strands penetrate through the corresponding standard section prefabricated parts; c, concrete is poured into the hollow part of the standard section prefabricated part; and step d, excavating a middle soil body. The adopted prefabricated parts can be produced in a factory in a centralized mode in advance and transported to the site to be assembled when needed, and the prefabricated parts are of hollow structures, light in weight, convenient to transport and high in construction efficiency.
一种预应力束合装配式沉井施工方法，包括如下步骤，步骤a，沿沉井待开挖区域的外周插入多个中空的预制构件，多个预制构件围成封闭的矩形支护结构，预制构件包括工作段预制构件和标准段预制构件，工作段预制构件位于沉井待开挖区域的四个角处，标准段预制构件位于沿周向相邻的两个工作段预制构件之间；步骤b，在沿周向相邻的两个工作段预制构件之间穿钢绞线并张拉，钢绞线穿过相应的标准段预制构件；步骤c，对标准段预制构件的中空部分灌注混凝土；步骤d，开挖中间土体。本发明采用的预制构件可以提前在工厂集中生产，需要时运输到现场拼装，预制件为中空结构，重量较小方便运输，施工效率高，属于地下工程施工技术领域。
