Segmental assembled circular open caisson and construction method thereof
The invention discloses a segment-assembled circular open caisson and a construction method thereof, and belongs to the technical field of assembled open caissons. The problems that in the prior art, a traditional cast open caisson is long in construction period, and an assembly type open caisson is poor in waterproof performance are solved. Prefabricated light high-strength concrete bodies are adopted for open caisson assembly, the top ends of upper light high-strength concrete circular plates, the top ends of middle light high-strength concrete circular plates and the top ends of lower light high-strength concrete circular plates are all provided with water stop belt grooves for installing water swelling rubber strips, and the outer walls are all coated with waterproof materials in the construction process; the light high-strength concrete circular plates are connected through the wedge-shaped body plug pins and the wedge-shaped body grooves and are assembled and fixed through the bolts and the assembly holes. The number and the positions of the wedge-shaped body grooves can be adjusted according to actual requirements, and the needed sinking depth is achieved by adding the number of the middle light high-strength concrete circular plates. The construction period is effectively shortened, the waterproof and anti-seismic performance is improved, and the construction method can be applied to open caisson engineering.
本发明公开了一种节段拼装圆形沉井及其施工方法，属于装配式沉井技术领域。解决了现有技术中的传统浇筑沉井施工周期长且装配式沉井防水性能较差的问题；本发明采用预制轻质高强混凝土体进行沉井装配，上部轻质高强混凝土圆形板、中部轻质高强混凝土圆形板、下部轻质高强混凝土圆形板顶端均设置安装遇水膨胀橡胶条的止水带凹槽，且施工过程中外壁均涂抹防水材料；轻质高强混凝土圆形板之间均通过楔形体插销和楔形体凹槽连接，通过螺栓和装配孔进行装配固定；可以根据实际需求对楔形体凹槽的数量和位置进行调整，通过添加中部轻质高强混凝土圆形板数量以达到所需下沉深度。本发明有效缩短了工期，提升了防水和抗震性能，可以应用于沉井工程。
