Abstract
The invention relates to a construction method for high and cold region tunnel hole body water resistance, and relates to a construction method applicable to high and cold region tunnel hole body water resistance. The method mainly solves the problem that the existing high and cold region tunnel hole body water resistance construction speed is low. A non-woven fabric is laid on the surface of a sprayed concrete layer of a tunnel hole body, a plurality of hot melting liners are arranged on the outer surface of the non-woven fabric, the hot melting liners and the non-woven fabric are fixed to the sprayed concrete layer through fasteners, and the hot melting liners are arranged according to the quincunx; an inner layer waterproof plate is welded to the hot melting liners on the fixed non-woven fabric through an electric hot melting device, a plurality of suspenders are manufactured through offcut of the waterproof plate, hemp ropes are pressed below the suspenders, the suspenders are welded to the inner layer waterproof plate through a welding gun, a heat preservation plate is laid on the outer surface of the inner layer waterproof plate, the hemp ropes penetrate through the heat preservation plate, the outer ends of the hemp ropes are exposed and fixedly provided with the hot melting liners, and an outer layer waterproof plate is welded to the outer surface of the heat preservation plate through the electric hot melting device. The construction method has the advantage of being high in construction speed.
Description
Technical field:
The present invention relates to a kind of construction method being applicable to extremely frigid zones tunnel trunk waterproof.
Background technology:
The method of current extremely frigid zones tunnel trunk waterproof construction first two-layer splash guard is fixed on tunnel trunk sprayed mortar surface, establishes connecting band, and then be inserted between two-layer splash guard by warming plate, and fixed by connecting band between two-layer splash guard.Due to be fixed on tunnel trunk sprayed mortar surface two-layer splash guard between spacing at about 5 ㎝, so assign warming plate very inconvenient, speed of application is slow.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of speed of application is fast, matter measured extremely frigid zones tunnel trunk waterproof construction method.
Above-mentioned purpose is achieved in that shotcrete layer surface non-woven fabrics being laid on tunnel trunk, several hot melt liners are established at non-woven fabrics external surface, and by nailing, hot melt liner and non-woven fabrics are fixed on shotcrete layer, described hot melt liner is pressed blossom type and is arranged, wherein the spacing of the adjacent hot melt liner in arch is 0.5 meter-0.8 meter, and the spacing of the adjacent hot melt liner in abutment wall place is 0.8 meter-1.0 meters;
With electric heat welding device internal layer splash guard is welded on fixing non-woven fabrics hot melt liner on, the suspender belt some that 2 ㎝ are wide, 8 ㎝ are long is made with the leftover pieces of splash guard, under the rope made of hemp is pressed in suspender belt, with welding gun, described suspender belt is welded on internal layer splash guard, warming plate is laid on the external surface of internal layer splash guard, the rope made of hemp passes from warming plate and its outer end is exposed, the rope made of hemp outer end of exposing from warming plate is fixed with hot melt liner, is welded on warming plate external surface by waterproof outer plate with electric heat welding device.
Described internal layer splash guard and waterproof outer plate are ECB splash guard; Described warming plate is the polyurethane thermal insulation board of 5 cm thicks.
Advantage of the present invention is: because it first fixes nonwoven layer, more fixing successively internal layer splash guard, warming plate and waterproof outer plate, so construction easily, speed of application is fast, quality good.
Accompanying drawing illustrates:
Accompanying drawing 1 is extremely frigid zones tunnel trunk waterproof construction method constructing structure schematic diagram of the present invention; In figure, 1 is non-woven fabrics, and 2 is nailings, and 3 is hot melt liners, and 4 is ropes made of hemp, and 5 is internal layer splash guards, and 6 is waterproof outer plates, and 7 is warming plates, and 8 is suspender belts, and 9 is shotcrete layers.
Detailed description of the invention:
Non-woven fabrics is laid on the shotcrete layer surface of tunnel trunk, several hot melt liners are established at non-woven fabrics external surface, and by nailing, hot melt liner and non-woven fabrics are fixed on shotcrete layer, described hot melt liner is pressed blossom type and is arranged, wherein the spacing (horizontal spacing and longitudinal pitch) of the adjacent hot melt liner in arch is 0.5 meter-0.8 meter, and the spacing (horizontal spacing and longitudinal pitch) of the adjacent hot melt liner in abutment wall place is 0.8 meter-1.0 meters; Non-woven fabrics is laid and is wanted degree of tightness appropriateness, makes it to be close to shotcrete layer surface.
With electric heat welding device internal layer splash guard is welded on the hot melt liner be fixed on non-woven fabrics, the suspender belt some that 2 ㎝ are wide, 8 ㎝ are long is made with the leftover pieces of splash guard, under the rope made of hemp is pressed in suspender belt, with welding gun, described suspender belt is welded on internal layer splash guard, warming plate is laid on the external surface of internal layer splash guard, the rope made of hemp passes from warming plate and its outer end is exposed, the rope made of hemp outer end of exposing from warming plate is fixed with hot melt liner, is welded on warming plate external surface by waterproof outer plate with electric heat welding device.
Described internal layer splash guard and waterproof outer plate are ECB splash guard; Described warming plate is the polyurethane thermal insulation board of 5 cm thicks.
