Anti-floating device for open caisson and construction method of anti-floating device
The invention relates to an anti-floating device for an open caisson and a construction method of the anti-floating device. After the open caisson sinks in place, a circle of reinforced concrete slab is manufactured outside the uppermost section of the open caisson wall, meanwhile, the concrete slab and a lower soil body are anchored through reinforcing steel bars, and then the periphery of the open caisson is subjected to soil covering and backfilling. When the open caisson is subjected to water pumping and bottom sealing and encounters high-water-level flood in the open caisson using process, the open caisson floating caused by too large buoyancy can be prevented. The device is convenient to manufacture and adjustable in size, and the arrangement position can be arranged on the well wall of the open caisson according to needs through calculation. The safety of the foundation and the structure during open caisson construction and use is effectively guaranteed, and the risk caused by open caisson floating is reduced.
本发明涉及一种沉井抗浮的装置及其施工方法，沉井下沉到位后，在沉井最上一节井壁外制作一圈钢筋混凝土板，同时将混凝土板与下部土体通过钢筋锚固，再对沉井周边进行覆土回填。在沉井进行抽水封底及在沉井使用过程中遇到高水位洪水时，本发明可以预防浮力过大引起沉井上浮。本发明制作方便，尺寸可调，布置位置可通过计算在沉井井壁上按需布设。本发明有效保证沉井施工和使用时地基和结构的安全，减少沉井上浮带来的风险。
