Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments, it is to be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.
The utility model provides a shield constructs section of jurisdiction concatenation seam percolating water and uses water shutoff structure, water shutoff structure include a plurality of shield constructs section of jurisdiction 1 and water shutoff device 6, have section of jurisdiction joint seam 2 between adjacent shield constructs the section of jurisdiction, and water shutoff device 6 corresponds and sets up in section of jurisdiction joint seam department 2.
The water plugging device 6 comprises a rubber water-blocking cushion 3 and a limiting plate 4. The rubber water-blocking cushion 3 is correspondingly arranged at the connecting seam 2 of the duct piece; limiting plate 4 is installed in the 3 outsides of rubber water blocking pad, and limiting plate 4 can carry out the fixed of position and increase rubber water blocking pad 3 and the laminating degree of section of jurisdiction joint seam 2 to rubber water blocking pad 3, optimizes the stifled water effect.
Further explain, limiting plate 4 includes horizontal limiting plate and vertical limiting plate, because can produce vertical section of jurisdiction concatenation seam between the shield constructs section of jurisdiction 1 about, consequently designed vertical limiting plate, because can form the ring form after the installation of shield constructs section of jurisdiction 1, shield constructs section of jurisdiction 1 and can produce horizontal section of jurisdiction concatenation seam between the upper and lower.
