Open caisson bottom sealing structure and construction method thereof
The invention discloses an open caisson bottom sealing structure and a construction method thereof, and relates to the technical field of open caisson construction engineering. The problems that the pouring thickness of a concrete sealing bottom of an existing open caisson is too large, the construction cost is increased, and resources are wasted are solved. The gridding beam is composed of transverse steel bars and longitudinal steel bars which are arranged in a criss-cross mode, the anchoring limiting devices are connected to the bottom of the gridding beam, the concrete layer wraps the gridding beam and the anchoring limiting devices, each anchoring limiting device comprises a steel stand column and an anchoring head connected to the bottom end of the steel stand column, and the top end of each steel stand column is perpendicularly and fixedly connected to the gridding beam. The construction method comprises the steps that after the open caisson is constructed to the designed elevation, the grid beam and the anchoring limiting device which are fixedly connected into a whole are arranged at the bottom of the open caisson, concrete is poured, and the poured concrete layer wraps the grid beam and the anchoring limiting device.
本发明的一种沉井封底结构及其施工方法，涉及沉井施工工程技术领域。针对现有沉井的混凝土封底浇筑厚度过厚，提高了施工成本，并造成资源浪费的问题。它包括由纵横交错设置的横向钢筋和纵向钢筋构成的网格梁，连接于网格梁底部的多个锚固限位装置，及包覆网格梁和锚固限位装置的混凝土层，锚固限位装置包括钢立柱，及连接于钢立柱底端的锚固头，钢立柱的顶端垂直固接于网格梁。施工方法：沉井施工至设计标高后，将固接为一体的网格梁和锚固限位装置置于沉井底部，浇筑混凝土，使得浇筑后的混凝土层包覆网格梁和锚固限位装置。
