Construction method of rock geological sheet pile cofferdam
The invention discloses a construction method of a rock geology sheet pile cofferdam, which comprises the following steps: S1, rotatably digging a guide hole in a rock ground by adopting guide hole equipment, and then backfilling sand in the hole for inserting and driving a steel sheet pile; s2, inserting and driving steel sheet piles by using a first layer of enclosing purlins as a guide; s3, mounting a first layer of inner support, pumping water in the cofferdam, backfilling sand, leveling and pouring a cushion layer, then forming a dry operation construction environment by using the backfilled sand, constructing a main bridge pile foundation, and driving profile steel upright posts in the cofferdam for supporting the longer inner support; and S4, after pile foundation construction is completed, excavation continues to be conducted in the cofferdam except the area nearby the bearing platform straining beam, the remaining two layers of surrounding purlins and inner supports are sequentially installed, part of the inner supports are supported on the unexcavated rock mass of the straining beam, and the rock mass is used for bearing force. The non-excavated rock mass is used for bearing force, and the method has the advantages that construction is easy and fast, stress is clear, cost is effectively saved, the construction progress is accelerated, energy is saved, environment friendliness is achieved, and later turnover is facilitated.
本发明公开了一种岩石地质板桩围堰的施工方法，包括以下步骤：S1、在岩石地采用引孔设备旋挖引孔，然后孔内回填砂，用于钢板桩的插打；S2、利用第一层围檩兼做导向插打钢板桩；S3、安装第一层内支撑，围堰内抽水，回填砂，整平并浇筑垫层，然后利用回填砂形成干作业施工环境，主桥桩基施工，并在围堰内打设型钢立柱用于支承长度较长的内支撑；S4、桩基施工完成后，除承台系梁附近区域，围堰内继续开挖，并依次安装余下两层围檩及内支撑，部分内支撑支承在系梁未开挖岩体上，利用岩体受力。本发明利用未开挖岩体受力，其具有施工简单快捷，受力明确，有效节约成本，加快施工进度，节能环保，利于后期周转方便等优点。
