Embodiment: one of the present embodiment is used for the waterproof construction of the compound section of jurisdiction of machinable, each for pin-connected panel tube coupling
Splice the waterproof between section of jurisdiction.As shown in Figure 1, the compound section of jurisdiction of the machinable is mixed by several steel pipe sheets 1 and several machinables
The assembled combined type section of jurisdiction in solidifying soil section of jurisdiction 2, shown in FIG. 1 is 2 faying face position of steel pipe sheet 1 and machinable concrete pipe sheet
The structural schematic diagram at place.If steel pipe sheet 1 and machinable concrete pipe sheet 2 are spliced by dry plate respectively.
Waterproof construction in the present embodiment includes waterproof construction in 1 range of steel pipe sheet, 2 range of machinable concrete pipe sheet
Waterproof construction at interior waterproof construction and steel pipe sheet 1 and 2 faying face of machinable concrete pipe sheet.
Specifically, the ring, longitudinal joint in 2 range of machinable concrete pipe sheet are made using hydro-expansive rubber sealing cushion 3
For waterproof measure, if wherein longitudinal joint refers to the piece being spliced to form between the dry plate section of jurisdiction of machinable concrete pipe sheet 2, and ring
Seam is then referred in the compound section of jurisdiction of machinable in 2 range of machinable concrete pipe sheet and the gap between adjacent section of jurisdiction.Can
It cuts the ring in 2 range of concrete pipe sheet, longitudinal joint and waterproof measure is used as using hydro-expansive rubber sealing cushion 3, water is swollen using meeting
Swollen rubber gasket 3 meets the expansive force generated after water and reaches waterproof efficacy.
Ring, longitudinal joint in 1 range of steel pipe sheet are used as waterproof measure using EPDM elastic rubber gasket 4, equally
Ground, if longitudinal joint refers to the piece being spliced to form between the dry plate section of jurisdiction of steel pipe sheet 1, and circumferential weld refers to 1 range of steel pipe sheet
