Abstract
The utility model relates to a waterproof structure of a shield tunnel duct piece. The waterproof structure of the shield tunnel duct piece is characterized in that two parallel circular seam waterproof tapes are arranged between the inner wall and the outer wall of the shield duct piece. When the waterproof structure of the shield tunnel duct piece is used, one way of water prevention is expanded into two ways of parallel water prevention for a shield tunnel duct piece waterproof system, and a plurality of circular seam vertical waterproof tapes perpendicular to the circular seam waterproof tapes are arranged between the two parallel circular seam waterproof tapes to form a plurality of waterproof partitions. Therefore, by means of the method, underground water is effectively prevented from entering a tunnel through vertical seams and circular seams, a leaking position can be accurately confirmed when leakage occurs on the tunnel so as to be favorable for people to take treating measures.
Description
Technical field
The utility model relates to the technical field of duct pieces of shield tunnel waterproof, and 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 affects tunnel safety, if ground water seepage, can affect the normal operation in tunnel and application life to tunnel internal.One waterproof system of the at present many employings of shield tunnel, 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 purpose of this utility model 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 simultaneously the waterproof subregion, when percolating water occurring in the tunnel, can find fast breakthrough, be convenient to fast processing, reduce expenses.
To achieve these goals, the technical solution of the utility model is: the waterproof construction of duct pieces of shield tunnel, it mainly comprises shield duct piece, and 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.
During use the utility model duct pieces of shield tunnel waterproof system by expanding to together the parallel waterproof of two pass, 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, the 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.
Description of drawings

Fig. 2 is the plan view of the vertical water blocking tape of circumferential weld of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The utility model mainly comprises shield duct piece, and shield duct piece is provided with inwall 1 and outer wall 2, it is characterized in that: be provided with the parallel circumferential weld water blocking tape 3 of twice between the inside and outside wall of shield duct piece.Be provided with the vertical water blocking tape 4 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 5 with twice circumferential weld water blocking tape, longitudinal joint water blocking tape seamless intersect vertical with the circumferential weld water blocking tape.Be provided with the vertical water blocking tape of the 3-30 bar circumferential weld 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 3-30 waterproof subregion with twice circumferential weld water blocking tape, longitudinal joint water blocking tape width 24mm～45mm, thickness 16mm～22mm, circumferential weld water blocking tape width 24mm～45mm, thickness 16mm～22mm.Distance between the twice longitudinal joint water blocking tape is identical with distance between the twice circumferential weld water blocking tape, and the position of longitudinal joint water blocking tape is corresponding with the position of circumferential weld water blocking tape.Circumferential weld water blocking tape water blocking tape vertical with circumferential weld adopts elastic rubber gasket to make, and material is the material that ethylene propylene diene rubber, water-expansible rubber or ethylene propylene diene rubber and water-expansible rubber are composited.The longitudinal joint water blocking tape adopts elastic rubber gasket to make, and material is the material that ethylene propylene diene rubber, water-expansible rubber or ethylene propylene diene rubber and water-expansible rubber are composited.The position of the vertical waterproof of the utility model and quantity can be adjusted according to section of jurisdiction block form and assembly unit situation, but will guarantee that the position of the vertical waterproof of circumferential weld between every ring is consistent with quantity.
Embodiment 1
Be provided with 16 vertical water blocking tapes of the circumferential weld vertical with the circumferential weld water blocking tape between the parallel circumferential weld water blocking tape of twice, the vertical water blocking tape of circumferential weld is separated into 16 waterproof subregions with twice circumferential weld water blocking tape.Be provided with the parallel longitudinal joint water blocking tape of twice in the shield duct piece, longitudinal joint water blocking tape seamless intersect vertical with the circumferential weld water blocking tape.Longitudinal joint water blocking tape width 24mm, thickness 16mm, circumferential weld water blocking tape width 24mm, thickness 16mm.Distance between the twice longitudinal joint water blocking tape is identical with distance between the twice circumferential weld water blocking tape, and the position of longitudinal joint water blocking tape is corresponding with the position of circumferential weld water blocking tape.Circumferential weld water blocking tape, the vertical water blocking tape of circumferential weld and longitudinal joint water blocking tape employing elastic rubber gasket etc. are made, and material is ethylene propylene diene rubber etc., and the technical indicator of ethylene propylene diene rubber is as follows:
Annotate: only illustrate wherein a kind of material here, also can adopt water-expansible rubber or the material that is composited is done water blocking tape.
By this waterproof construction, can prevent effectively that underground water from entering tunnel internal by longitudinal joint and circumferential weld, form simultaneously the waterproof subregion, when percolating water occurring in the tunnel, can find fast breakthrough, be convenient to fast processing, reduce expenses.
