Bare rock riverbed bridge foundation hanging box cofferdam construction method
The invention relates to the technical field of riverbed bridges, and discloses a bare rock riverbed bridge foundation hanging box cofferdam construction method which comprises an integral external mechanism, the integral external mechanism further comprises an integral bottom plate, the integral external mechanism is pulled up by means of the mass of a hanging box, mechanical kinetic energy is accumulated in the movement process of a water entry spring, and the whole bottom plate is arranged in the hanging box. When the hanging box moves downwards, a water source enters the hanging box from the integral hole, when the hanging box moves downwards and the water inlet main plate makes contact with the bottom base layer, the water inlet main plate makes contact with the water inlet top plate and moves upwards, limitation of the water inlet side spring is relieved, the water inlet side plate limits resetting of the water inlet main plate, and therefore the effect of closing the bottom valve is achieved; water cannot enter the hanging box temporarily, a stable working environment is provided for the follow-up concrete procedure, and the construction efficiency of the process is improved.
本发明涉及河床桥梁技术领域，且公开了裸岩河床桥梁基础吊箱围堰施工方法，包括整体外部机构，所述整体外部机构还包括有整体底板，本发明利用吊箱自身的质量，将整体外部机构拉起，其中入水弹簧在运动过程中积蓄机械动能，为后续提供复位动力，当吊箱向下移动时，水源从整体孔洞进入吊箱内部，在吊箱下移时，入水主板接触底部基层时，入水主板接触入水顶板并向上移动，解除入水侧弹簧的限制，使入水侧板限制入水主板的复位，从而达到关闭底部阀门的效果，使水暂时无法进入吊箱内部，为后续混凝土工序提供较为稳定的工作环境，提高过程的施工效率。
