METHOD FOR PREVENTING MANHOLE FROM RISING
To provide a novel method for preventing a manhole from rising.SOLUTION: The present invention includes: installing a base 10 with a predetermined height on a bottom surface 3a of a manhole 1 and then positioning a flexible bag body 11 above the base 10; and filling the bag body 11 with water 12 and using the weight of the water 12 to resist the buoyancy that acts on the manhole 1. This prevents the manhole from rising. Another method includes: covering, using a lid, a channel 2 that is formed on the bottom surface 3a of the manhole 1, and then filling the inside of the channel 2 with water and using the weight of the water to resist the buoyancy that acts on the manhole. This prevents the manhole from rising.SELECTED DRAWING: Figure 1
【課題】マンホールの浮上を防止するための新たな方法を提供する。【解決手段】マンホール１の底面３ａに所定の高さを有する架台１０を設置した後、該架台１０よりも上部に可撓性を有する袋体１１を配置し、袋体１１に水１２を充填して充填された水１２の重さをマンホール１に作用する浮力に対抗させることで浮上を防止する。他の方法として、マンホール１の底面３ａに形成された流路２を蓋体によって被蓋した後、内部に水を充填し、該充填された水の重さをマンホールに作用する浮力に対抗させることで浮上を防止する。【選択図】図１
