Open caisson first-section sinking soil taking construction method
The invention discloses an open caisson first-section sinking soil taking construction method. The method includes the steps of pre-storing plain soil in a field, laying the plain soil along the periphery of a first section of an open caisson in a layered mode, performing compaction by using a machine, and performing manual auxiliary slope finishing to form a construction platform with a gradient; and symmetrically excavating soil at the same time through excavators at the two sides of the construction platform. The open caisson first-section sinking soil taking construction method is easy to operate, convenient and fast to construct and clear in technological process. The pre-stored soil in the field is utilized nearby by the piling soil taking construction platform, so that the construction period is shortened, meanwhile, an operation platform is provided for a telescopic boom excavator, conventional equipment can be directly used, the construction efficiency is improved, and the construction cost is reduced. By means of backfill soil side pressure and friction force around the construction platform, the risk of deviation or uneven sinking in the sinking process of the first section of the open caisson is effectively reduced, and the construction quality is ensured.
本发明公开了一种沉井首段下沉取土施工方法，使用场内预存素土，沿第一节沉井四周分层铺设素土，使用机械进行压实，人工辅助修坡，形成带坡度的施工平台；在施工平台两侧的挖掘机同时进行对称挖土。本发明操作简单、施工简便快捷、工艺流程清晰。堆筑取土施工平台就近利用场内预存土，缩短了施工工期，同时给伸缩臂挖掘机提供了作业平台，让常规设备可以直接使用，提升了施工效率、降低了施工成本。利用施工平台四周的回填土侧压力和摩擦力，有效降低了沉井首段下沉中，发生偏移或不均匀下沉的风险，确保施工质量。
