A water seepage pipe comprises an inner pipe unit and an outer pipe unit sleeved on a periphery of the inner pipe unit. A manufacturing method for the water seepage pipe includes the steps of: coating an inner waterproof layer on an inner peripheral surface of an inner soft fabric layer to form an inner pipe body coating an outer waterproof layer on an inner peripheral surface of an outer fabric layer to form an outer pipe body utilizing an inner connection thread to connect two sides of the inner pipe body by machine sewing utilizing an outer connection thread to connect two sides of the outer pipe body by machine sewing finally sleevingly disposing the outer pipe unit on the inner pipe unit and enabling the outer connection thread and the inner connection thread to be located at two opposite sides. Accordingly, the water seepage pipe can be flattened to reduce volume for storage when not in use, thereby attaining efficacies of optimistic space utilization and collection convenience.一種滲水管,包含:一個內管單元,及一個套設在該內管單元外圍之外管單元。而一種滲水管製造方法,則包含下列步驟:在一片內軟布層之內周面塗布一層內防水層而成為一個內管本體,且在一片外軟布層之內周面塗布一層外防水層而成為一個外管本體,再利用一條內連接線將該內管本體之兩側邊車縫連接,並利用一條外連接線將該外管本體之兩側邊車縫連接,最後將該外管單元套設在該內管單元外圍,且令外連接線與內連接線位於兩相反側。故當不使用時,即可將該滲水管壓扁收納,以縮小體積,較不佔用空間,所以易於收藏。1...中心線2...內管單元21...內管本體211...內側邊部212...內連接部213...內軟布層215...內防水層216...內管通道217...內管縫隙22...內連接線3...外管單元31...外管本體311...外側邊部312...外連接部313...外軟布層315...外防水層316...外管通道317...外管縫隙32...外連接線
