FROST HEAVE PREVENTION SYSTEM AND FROST HEAVE PREVENTION METHOD
To provide a frost heave prevention system and a frost heave prevention method capable of preventing frost heave in the ground around a cylindrical object buried in a pavement ground.SOLUTION: A frost heave prevention system 2 is provided with: a catchment sheet 8 collecting water from the ground around a cylindrical object 6 buried so that it vertically extends in a cylindrical shape and its top end surface is flush with a surface 4a of a pavement ground 4; and a drain sheet 10 draining water collected with the catchment sheet 8 to an inside of the ground deeper than a predetermined depth. The frost heave prevention method includes: a process of installing the cylindrical object 6 at a predetermined burring site so that is vertically extends in the cylindrical shape and its top end surface is flush with the surface 4a of the pavement ground 4; a process of laying the catchment sheet 8 collecting the water from the ground around the cylindrical object 6; and a process of laying the drain sheet 10 draining the water collected with the catchment sheet 8 to the inside of the ground deeper than the predetermined depth.SELECTED DRAWING: Figure 1
【課題】舗装地に埋設された筒状物の周囲地盤の凍上を防止することができる凍上防止システムおよび凍上防止工法を提供する。【解決手段】凍上防止システム２は、上下方向に筒状に延び且つ上端面が舗装地４の表面４ａと面一となるように埋設された筒状物６の周囲地盤から水を集める集水シート８と、集水シート８が集めた水を所定深さよりも深い地盤内部に排出する排水シート１０とを備える。凍上防止工法は、上下方向に筒状に延び且つ上端面が舗装地４の表面４ａと面一となるように筒状物６を埋設予定箇所に設置する工程と、筒状物６の周囲地盤から水を集める集水シート８を敷設する工程と、集水シート８が集めた水を所定深さよりも深い地盤内部に排出する排水シート１０を敷設する工程とを含む。【選択図】図１
