摘要

PPROBLEM TO BE SOLVED: To provide a vertical tube floating prevention device can hold the level of underground water normally, exhibit a high drainage capacity when a ground is liquefied in an earthquake, miniaturizable, and hardly obstructing a manhole in a vertical tube, and also provide a drain structure formed in the device. PSOLUTION: An underground water inflow hole 3 is formed in the vertical tube 2 buried in the ground 1. An underground water introduction part 4 for introducing underground water through the underground water inflow hole 3 is formed in the vertical tube 2. A lower drain port 6 is formed in the underground water introduction part 4. The device includes an opening/closing operation mechanism 7 having an opening/closing part 5 for openably closing the lower drain port 6 for stopping water and opening the opening/closing part 5 when the hydraulic pressure of the underground water introduced into the underground water introduction part 4 is detected to reach a predetermined pressure and an opening operation holding mechanism 8 for holding the opening state of the opening/closing part 5 when the drain from the lower drain port 6 opened by the opening/closing operation mechanism 7 is detected.

要解决的问题：提供一种垂直管防浮装置，该装置可正常容纳地下水位，在地震中液化地面时具有高排水能力，可小型化且几乎不会阻塞垂直管中的人孔，并且还提供形成在器件中的漏极结构。

解决方案：在埋入地下1的竖直管2中形成地下水流入孔3。在竖直管2中形成用于通过地下水流入孔3引入地下水的地下水引入部4。在地下水导入部4上形成有下部排水口6。该装置具备开闭操作机构7，该开闭操作机构7具有用于将下部排水口6开闭而使水停止并打开该开闭部5的开闭部5。当检测到被引入到地下水引入部分4中的地下水的液压达到预定压力时，打开操作保持机构8用于在从下部排水口排水时保持打开/关闭部分5的打开状态。检测到由打开/关闭操作机构7打开的图6中所示的位置。
