Depressurization well plugging device and method combined with curing capsule
According to the depressurization well plugging device and method combined with the curing capsule, in a pouring module of the device, a ribbed high-elastic capsule is arranged in a depressurization well pipe, a center pipe is inserted in the middle of the ribbed high-elastic capsule, the outer side of the ribbed high-elastic capsule is tightly attached to the inner wall of the depressurization well pipe to form sealing, and the inner side of the ribbed high-elastic capsule is tightly attached to the outer side of the center pipe; the ribbed high-elastic capsule is connected with the grouting pump through a high-pressure air pipe and controlled by the grouting pump to expand or contract in the radial direction. The central pipe is a hollow circular pipe, the bottom is open, and the top is connected with the grouting pump control valve through the pressure relief control valve; the top of a limiting pressing rod in the fixing module is fixedly connected to the top face of the foundation pit bottom plate through a limiting bolt, and the bottom of the limiting pressing rod abuts against the top of the ribbed high-elastic capsule and is used for fixing the vertical position of the ribbed high-elastic capsule and preventing the ribbed high-elastic capsule from floating upwards. According to the invention, the high-elastic ribbed capsule is filled with the quick-setting epoxy resin, so that three effective plugging of the capsule upper well pipe, the curing capsule and the capsule lower filter pipe section can be formed, and stable and reliable permanent plugging is formed.
本发明涉及一种结合固化胶囊的降压井封堵装置及方法，该装置的灌注模块中带肋高弹胶囊置于降压井管内，中间插有中心管，带肋高弹胶囊外侧与降压井管的内壁紧密贴合，形成密封，内侧与中心管的外侧紧密贴合连接，带肋高弹胶囊通过高压气管与注浆泵连接，由注浆泵控制其径向膨胀或收缩；中心管为中空圆管，底部开口，顶部分别通过泄压控制阀和灌浆泵控制阀相连；固定模块中的限位压杆顶部用限位螺栓固定连接在基坑底板顶面上，底部顶靠在带肋高弹胶囊的顶部，用于固定带肋高弹胶囊的竖直位置，防止其上浮。本发明利用速凝环氧树脂填充高弹带肋胶囊，可形成胶囊上部井管、固化胶囊、胶囊下部滤管段三道有效封堵，形成稳定可靠的永久封堵。
