Construction method combining deep well shallow excavation and open caisson method
The invention relates to the technical field of rotational flow pool open caisson construction, in particular to a construction method combining deep well shallow excavation and an open caisson method, and solves the technical difficulty of rotational flow pool construction under the conditions of narrow site and uneven geological conditions. Firstly, an excavator is adopted to excavate an open caisson deep foundation pit, an upper cushion layer is built, then the open caisson is manufactured in a segmented mode, each open caisson section is constructed through a drainage sinking technology, meanwhile, a thixotropic slurry sinking assisting method is used for assisting sinking and reducing resistance, and the sinking work of the open caisson is further guaranteed. Compared with the prior art, the construction method has the advantages that the stability of surrounding structures is guaranteed, the earth cutting amount is reduced, the machine team and labor cost is saved, the construction period is shortened, the working efficiency is improved, and technical innovation is completed from the aspects of earth cutting construction, a precipitation technology, an open caisson sinking technology and the like.
本发明涉及旋流池沉井的施工技术领域，具体是一种深井浅位开挖与沉井法相结合的施工方法，该方法采用了一种深井浅位开挖与沉井法相结合的施工方法，解决了场地狭窄及高低不平地质状况的旋流池施工技术难点，先采用挖机挖掘出沉井深基坑，打上垫层后再分段制作沉井，每节沉井采用排水下沉工艺施工，同时使用触变泥浆助沉法助沉减阻，进一步保障沉井下沉工作。该施工方法相比现有技术保障了周边构筑物的稳定性，减少了挖土量，节省了机械台班和人工费用，缩短施工工期提高了工作效率，从挖土施工、降水技术、沉井下沉工艺等方面完成技术创新。
