Abstract
The invention discloses a waterproof structure of a shield tunnel segment. The waterproof structure of the shield tunnel segment is characterized in that two parallel circular-seam waterproof zones are arranged between the inner wall and the outer wall of the shield segment; a plurality of circular-seam perpendicular waterproof zones perpendicular to the circular-seam waterproof zones are arranged between the two circular-seam waterproof zones; and the circular-seam perpendicular waterproof zones divide the two circular-seam waterproof zones into a plurality of waterproof subzones. In use, a waterproof system of the shield tunnel segment is developed into double parallel waterproof zones from one waterproof zone by adopting the the waterproof structure of the shield tunnel segment; moreover, a plurality of the circular-seam perpendicular waterproof zones perpendicular to the circular-seam waterproof zones are arranged between the two circular-seam waterproof zones, so that a plurality of the waterproof subzones are formed; the waterproof structure of the shield tunnel segment can effectively prevent underground water from entering a tunnel through longitudinal seams and circular seams; and meanwhile, when the leakage occurs to the tunnel, a leakage part can be determined correctly, which is beneficial to adopting a treatment measure.
Description
Technical field
The present invention relates to the technical field of duct pieces of shield tunnel waterproof, specifically duct pieces of shield tunnel prevents that underground water from passing through the method that circumferential weld (each ring between), longitudinal joint (between each piece) enter tunnel internal.
Background technology
At present, the tunnel of China's shield construction is more and more, and underground water is the principal element that influences tunnel safety, if ground water seepage, can influence the normal operation in tunnel and application life to tunnel internal.One waterproof system of the many employings of shield tunnel at present, in case lost efficacy, underground water just can leak out to tunnel internal, can not accurately determine to be unfavorable for taking treatment measures by seepage place simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of waterproof construction of duct pieces of shield tunnel, it can prevent effectively that underground water from entering tunnel internal by longitudinal joint and circumferential weld, forms the waterproof subregion simultaneously, when percolating water occurring in the tunnel, can find breakthrough fast, be convenient to fast processing, reduce expenses.
To achieve these goals, technical scheme of the present invention is: a kind of waterproof construction of duct pieces of shield tunnel, it mainly comprises shield duct piece, shield duct piece is provided with inner and outer wall, it is characterized in that: be provided with the parallel circumferential weld water blocking tape of twice between the inside and outside wall of shield duct piece, be provided with the vertical water blocking tape of several circumferential welds vertical with the circumferential weld water blocking tape between the twice circumferential weld water blocking tape, the vertical water blocking tape of circumferential weld is separated into several waterproof subregions with twice circumferential weld water blocking tape.
During use the present invention duct pieces of shield tunnel waterproof system by expanding to the parallel waterproof of two pass together, and the vertical water blocking tape of some circumferential welds perpendicular to the circumferential weld water blocking tape is set between the parallel circumferential weld water blocking tape of twice, form some waterproof subregions, this method can prevent effectively that underground water from entering tunnel internal by longitudinal joint and circumferential weld, simultaneously when tunnel generation seepage, can accurately determine seepage place, be beneficial to and take treatment measures.
