River bank cofferdam structure dismantling construction method
The invention discloses a river bank cofferdam structure dismantling construction method. The river bank cofferdam structure dismantling construction method is used for dismantling a river bank cofferdam structure, and the river bank cofferdam structure comprises a foundation pit, a first support, a second support, a third support, a steel pipe pile, a plain concrete continuous wall and a cofferdam outer layer which are sequentially arranged from inside to outside; the river bank cofferdam structure dismantling construction method comprises the following steps that S1, the third support is dismantled; S2, the second support is dismantled; S3, the foundation pit is filled with water, so that the water level in the foundation pit is flush with the water line outside the cofferdam outer layer; s4, the plain concrete continuous wall and the outer layer of the cofferdam are dismantled; S5, the first support is dismantled; and S6, the steel pipe pile is dismantled. According to the river bank cofferdam structure dismantling construction method, soil and sand backfilling in the prior art is changed into irrigation backfilling, advantages of the surrounding environment are utilized, the pressure value of river water on the outer side of the cofferdam and backfilling water on the inner side of a cofferdam is stabilized when irrigation backfilling reaches a certain height, then the river bank cofferdam structure is dismantled, and the method has the advantages of being high in efficiency, low in cost and the like.
本发明公开了一种河岸围堰结构拆除施工方法，用于对河岸围堰结构进行拆除，河岸围堰结构包括自内向外依次布置的基坑、第一道支撑、第二道支撑和第三道支撑、钢管桩、素混凝土连续墙和围堰外层；河岸围堰结构拆除施工方法包括如下步骤：S1、拆除第三道支撑；S2、拆除第二道支撑；S3、基坑灌水，使得所述基坑内的水位高度与围堰外层外的水位线平齐；S4、拆除素混凝土连续墙和围堰外层；S5、拆除第一道支撑；S6、拆除钢管桩。本发明将现有技术中的土砂回填改成灌水回填，利用周边环境优势，当灌水回填达到一定高度使得围堰外侧河水与围堰内侧回填水的压力值达到稳定后，再对河岸围堰结构进行拆除施工，具有效率高、成本低等优点。
