Assembled open caisson construction method and prefabricated concrete segments of assembled open caisson
The invention provides an assembled open caisson construction method and prefabricated concrete segments of an assembled open caisson. The assembled open caisson comprises cutting shoes and open caisson walls. The method comprises the steps that a cushion layer position used for allowing the cutting shoes to be arranged is determined from an excavated foundation pit, and a cushion layer is arranged or poured at the cushion layer position; the cutting shoes are arranged or poured on the cushion layer, and the prefabricated concrete segments matched with the cutting shoes are determined; the cutting shoes are controlled to sink, after the cutting shoes sink by a preset distance range, the plurality of prefabricated concrete segments are arranged on the top faces of the cutting shoes throughconnecting assemblies on the prefabricated concrete segments, and one well wall layer with the peripheral side closed is formed on the top faces of the cutting shoes, wherein adjacent components represent the prefabricated concrete segments or the cutting shoes adjacent to the prefabricated concrete segments; whether the total sinking distance of the cutting shoes reaches a target distance or notis detected; if not, the cutting shoes are controlled to sink, and a plurality of prefabricated concrete segments are arranged on the top faces of the prefabricated concrete segments of the well walllayer on the top layer in a staggered mode every time the cutting shoes sink within a preset distance range; and if yes, assembled open caisson construction is completed.
本申请提供一种组装式沉井施工方法及组装式沉井的预制砼管片，组装式沉井包括刃脚和沉井井壁，方法包括：从挖掘好的基坑中确定出用于安装刃脚的垫层位置，并在垫层位置安装或浇筑垫层；在垫层上安装或浇筑出刃脚，以及，确定出与刃脚匹配的预制砼管片；控制刃脚下沉，并在刃脚下沉预设距离范围后，通过预制砼管片上的连接组件，将多个预制砼管片安装于刃脚的顶面，以在刃脚的顶面上构成一层周侧封闭的井壁层，其中，相邻部件表示与该预制砼管片相邻的预制砼管片或刃脚；检测刃脚下沉的总距离是否达到目标距离；若否，控制刃脚下沉，刃脚每下沉预设距离范围，在顶层井壁层的预制砼管片的顶面上交错安装多个预制砼管片；若是，完成组装式沉井施工。
