Underground super-thick side wall formwork supporting system and construction method
The invention discloses an underground super-thick side wall formwork supporting system and a construction method. According to the system, split bolts, formworks and profile steel supports are combined for formwork supporting, and the super-thick side wall concrete structure formworks are reasonable in stress and safe in structure; the formworks and the profile steel supports are connected through hook bolts and the split bolts, hoisting movement and re-assembling of the formworks and the profile steel supports are facilitated, and the formwork engineering turnover efficiency is improved; and the profile steel supports replace inclined struts in a traditional formwork supporting system, installation is convenient and fast, and the stability and safety of the whole formwork engineering are improved. The split bolts and steel bar connectors of an underground diaphragm wall are mechanically connected and then are used for split formwork supporting, the construction efficiency can be improved, the construction cost is reduced, and the connection survival rate and the connection quality are better controlled. Grout stopping limiting pieces are arranged at the joints of threaded rods of the split bolts, the formworks and recyclable threaded rods, the grout stopping limiting pieces are tightly attached to the formworks, the functions of grout stopping, water stopping and limiting are achieved, and the water stopping and seepage preventing effects during operation can be guaranteed.
本发明公开了一种地下超厚侧墙模板支撑体系及施工方法，该体系采用对拉螺栓、模板和型钢支架组合支模，保证超厚侧墙混凝土结构模板受力合理和结构安全；模板与型钢支架通过钩栓和对拉螺栓连接，便于模板和型钢支架的吊装移动及再次组拼，提高模板工程周转效率；型钢支架代替传统模板支撑系统中的斜撑，安装便捷，增加整个模板工程的稳定性和安全性。对拉螺栓与地下连续墙的钢筋接驳器机械连接后对拉支模，能够提高施工效率，减少施工成本，更好地控制连接成活率和连接质量。对拉螺栓的螺纹杆与模板、可回收螺杆连接处设置止浆限位片，止浆限位片与模板紧密贴合，起到止浆、止水和限位的作用，能够保证运营期间的止水防渗效果。
