推進管

Propulsive pipe

Abstract

(57)【要約】 【課題】 推 進中における蛇行や、曲線推進による曲げの 作用に強く、施工後における高土被りによって発生する 高土圧等による外圧強度に強く、更に、耐震性にも対応 可能な推進管を実現する。 【解決手段】 管軸方向ほぼ中央部11の外周を、管全 長のほぼ半分長さ程度の円筒状 で 幅広の補強管21で一 体に被覆し、管中央部に対する曲げ強度に対応可能に形 成した。
PROBLEM TO BE SOLVED: To provide a propulsive pipe which is resistible to an flexural effect caused by meanderings during propulsion and curved propulsion, and to an external pressure strength caused by a high earth pressure or the like produced by covering with thick earth after execution of propulsion, and also can cope with an earthquake. SOLUTION: An outer periphery of an approximately central portion 11 in the axial direction of the propulsive pipe is covered integrally with a cylindrical reinforcing pipe 21 with a large width and an almost half of the entire length of the propulsive pipe to thereby cope with flexural strength to the central portion 11 of the propulsive pipe.
