Open caisson elevation control process
The invention relates to the field of building engineering construction, in particular to an open caisson elevation control technology, an open caisson comprises a shaft, a lug plate arranged at the top of the shaft and a blade foot arranged at the bottom of the shaft, and after the shaft sinks to the designed elevation below the ground, the lug plate can be exactly hung on the ground; comprising the following steps: S1, determining ear plate parameters; s2, site preparation; s3, laying a cushion layer; s4, the open caisson is manufactured, and the lug plates, the shaft and the blade feet are integrally cast and formed; s5, the open caisson sinks, the open caisson is controlled to sink to the designed elevation, and at the moment, the lug plates are exactly placed on the ground concrete cushion layer; s6, bottom sealing concrete and bottom plate concrete are poured; s7, after the bottom sealing concrete and the bottom plate concrete reach the design strength, whether the open caisson is subjected to super sinking or not is judged, if not, the lug plates are chiseled away, and otherwise, the lug plates are reserved; the open caisson construction method has the advantages that through the process measures, when open caisson construction is conducted in the soft soil area, the elevation error of open caisson construction can be effectively controlled, the construction quality and safety are guaranteed, the construction cost is effectively reduced, and it is guaranteed that a project is conducted on schedule.
本发明涉及建筑工程施工领域，尤其涉及一种沉井标高控制工艺，所述沉井包括井筒、设置于井筒顶部的耳板、设置于井筒底部的刃脚，所述井筒下沉至地面以下设计标高后，耳板恰好可挂在地面；包括以下步骤：S1.确定耳板参数；S2.场地准备；S3.铺设垫层；S4.沉井制作，所述耳板、井筒、刃脚整浇成型；S5.沉井下沉，控制沉井下沉至设计标高，此时耳板恰好搁置在地面混凝土垫层上；S6.浇筑封底混凝土和底板混凝土；S7.在封底混凝土和底板混凝土达到设计强度后，判定沉井是否会出现超沉，若不会出现超沉，则凿除耳板，否则，保留耳板；优势在于，通过上述工艺措施，在软土地区进行沉井施工时，可以有效控制沉井施工的标高误差，确保施工质量和安全，有效降低了施工成本，保证工程按期进行。
