TUNNEL REPAIRING FILLER
PROBLEM TO BE SOLVED: To provide a tunnel repairing filler for mainly filling in a cavity part and a repairing form in an existing tunnel, capable of securing safety from danger of exfoliation and a form fall of a tunnel skin surface by wind pressure and vibration generated when a vehicle passes.SOLUTION: A tunnel repairing filler includes (a) cement, calcium aluminate, gypsum, a coagulation conditioner and water, and has the following (b)-(e). (b) a flow value by a cylinder method determined in an NEXCO test method 313 is 150 mm or more, (c) lateral pressure after one hour when finishing filling is 0.5 or less to a maximum value of lateral pressure just after filling, (d) compression strength of material age of 28 days is 8 N/mmor more, and (e) density is 1.4 t/mor more.SELECTED DRAWING: None
【課題】車両通過時に発生する風圧、振動等によりトンネル肌面の剥落や型枠落下の危険から安全を確保可能な、主に既設トンネル内の空隙部や補修用型枠へ充填するためのトンネル補修用充填材の提供。【解決手段】（ａ）セメント、カルシウムアルミネート類、石膏、凝結調整剤及び水を含有し、次の（ｂ）〜（ｅ）を具備するトンネル補修用充填材。（ｂ）ＮＥＸＣＯ試験方法３１３に定められたシリンダー法によるフロー値が １５０ｍｍ以上、（ｃ）充填終了１時間後の側圧が充填直後の側圧の最大値に対して０．５以下、（ｄ）材齢２８日の圧縮強度が ８Ｎ／ｍｍ2以上、（ｅ）密度が １．４ｔ／ｍ3以上【選択図】なし
