Definitions

  • This invention relates to a waterproofing method for tunnels.
  • paste, mortar and concrete are used as general terms to refer to cement concrete.
  • the principal tunnel construction method in Japan at present is the NATM method.
  • the NATM construction method is a method in which primary coating is performed by means of spray mortar or spray concrete immediately after excavation of the tunnel to prevent falling of rock and water leakage in the excavation region, after which a secondary coating concrete is applied to stabilize the tunnel by maintaining tunnel strength.
  • a waterproofing sheet is installed for the purpose of waterproofing and insulation between the primary coating concrete and the secondary coating concrete so that leakage of water into the tunnel can be prevented and so that cracks due to binding of the secondary coating concrete to earth mounds or movement of earth mounds can be prevented.
  • TBM construction method tunnel boring machines
  • waterproofing sheets are installed for the same objectives.
  • the width of the sheet is narrow, being 1 to 2 m, there are the problems that it takes great effort and trouble and it is uneconomical when the ends of the waterproofing sheets are overlaid on each other and joined by welding. ! [0004]
  • waterproofing sheets and the secondary coating concrete due to damage of the waterproofing sheet functionally by poorly welded components and by irregularities in the excavation surface so that waterproofing capacity is not obtained.
  • the inventors conducted various studies of the aforementioned problems. As a result, they perfected this invention by discovering a tunnel waterproofing construction method whereby a waterproofing sheet that is adhesive to the secondary coating cement concrete is installed on the primary spray cement concrete surface before installing the secondary coating cement concrete, and, in which, by making it into a single entity with the secondary coating cement concrete, infiltration of water between the waterproofing sheet and the secondary coating concrete because of poor weld sites and damage of the ends of the waterproofing sheets is prevented, leakage of water is prevented even when cracks are generated in the secondary coating cement concrete and waterproofing capacity can be greatly increased.
  • this invention is a tunnel waterproofing method characterized
  • a tunnel waterproofing method characterized in that a primary spray cement concrete is sprayed on the excavation surface of the tunnel, after which a buffer-water conducting layer is established in said primary spray cement concrete surface, a secondary coating cement concrete and a waterproofing sheet having adhesiveness are installed on said secondary coating cement concrete such that the secondary coating cement concrete is established on said waterproofing sheet surface; and a tunnel waterproofing method further characterized in that the waterproofing sheet is a multilayer waterproofing sheet that has a layer that has adhesiveness with the installed secondary coating cement concrete.
  • This invention is a construction method in which the waterproofing sheet and the tunnel are made into a single entity by spraying, preferably, a fast-drying cement concrete onto the excavated tunnel surface, after which a waterproofing
  • This waterproofing sheet allows for follow-up of cracking of cement concrete due
  • waterproofing sheet that is made into a single entity with the secondary coating cement concrete prevents water leakage with good follow-up capacity and without damage occurring even when cracks are generated in the tunnel itself, waterproofing capacity is increased to a great extent by comparison to conventional waterproofing construction methods.
  • Examples of waterproofing sheets that are adhesive with secondary coating cement concrete include uncrosslinked rubber sheets such as isoprene rubber and natural rubber.
  • cement concrete may also contain antioxidants, ultraviolet radiation absorbents
  • the layer having adhesiveness with the secondary cement concrete with a polymeric sheet from the standpoint of increasing the insulation effect with the secondary coating cement concrete if it has been bound with the earth mound.
  • a layer that is adhesive with the secondary coating cement concrete and a multilayer waterproofing sheet that is laminated with a polymeric sheet are used, they are installed so that the primary spray cement concrete surface side and the polymeric sheet are in contact and the secondary coating cement concrete is installed on the waterproofing sheet surface side that is adhesive with the secondary coating cement concrete.
  • Examples of the material of the polymeric sheet can include high-density polyethylene, low-density polyethylene, copolymers of ethylene vinyl acetate (EVA) and polypropylene. Of these, high-density polypropylene is preferable from the standpoint of insulation effect, strength, crack follow-up capacity and price.
  • EVA ethylene vinyl acetate
  • a buffer-water conducting layer may be established before installing the waterproofing sheet that is adhesive with the secondary coating cement concrete for the purpose of increasing the insulation effect, decreasing water pressure in sites in which there is a great deal of groundwater and increasing the waterproofing effect.
  • buffer-waterproofing layers can include layers that are formed by spraying a fibrous substance such as pulp nonwoven fabrics of fibers such as polyester fibers and polypropylene and plates or irregular shapes.
  • the waterproofing construction method can be used in the bedding portion of the tunnel and displays great effectiveness in preventing water leakage from the bedding component.
  • a U-shaped simulation tunnel having openings of 4 m, a height of 3.5 m and a length of 3 m was made. Irregularities of the tunnel earth mound surface were presumed in the simulation tunnel and fifteen concrete blocks of 15 cm in width, 20 cm in height and 20 cm in length were installed at suitable intervals to form an irregular surface.
  • Fast-drying mortar was used as the primary spray mortar and was sprayed so that the fast-drying mortar was 10 cm in thickness.
  • a multilayer waterproofing sheet having adhesiveness to the secondary coating concrete (brand name, "Preprufe 300," manufactured by the Grace Construction Products Company of the United States; a two-layer sheet comprised of two layers, a layer having adhesiveness to concrete and a polyethylene layer; 2.7 mm in thickness) was affixed by riveting to the primary spray mortar surface.
  • the secondary coating concrete was applied to a thickness of 30 cm. To simulate damage to the multilayer waterproofing sheet, cuts were made in a part of it.
  • the multilayer waterproofing sheet that was used had adhesiveness, the multilayer waterproofing sheets could be adhered to each other satisfactorily simply by superimposing the ends of the multilayer waterproofing sheets on each other. For this reason, execution capacity was extremely good and an excellent value of 1.7 N/mm was obtained for adhesive strength of the superimposed parts.
  • Adhesive strength with the concrete In accordance with ASTM D 903 (90 degree peeling strength). Adhesive strength of superimposed portions: In accordance with ASTM D 1876 (Determinations in the case in which multilayer waterproofing sheets are superimposed).
  • Example 2 The same procedure was carried out as in Example 1 except that the multilayer waterproofing sheet having adhesiveness with the secondary coating concrete that was used was a product of the brand name "Santacke * Sheet” (isoprene rubber waterproofing sheet, a nonwoven fabric lined product, manufactured by Hayakawa Rubber).
  • solder * Sheet isoprene rubber waterproofing sheet, a nonwoven fabric lined product, manufactured by Hayakawa Rubber.
  • Example 2 The same procedure was carried out as in Example 1 except that a waterproofing sheet made of EVA (which did not have adhesiveness with the
  • the secondary coating cement concrete and the waterproofing sheets into a single entity using the waterproofing sheets of this invention having adhesiveness with the secondary coating cement concrete, water does not infiltrate between the gap between the waterproofing sheets and the secondary coating concrete and excellent waterproofing capacity can be assured even if a part of the waterproofing sheets is damaged.
  • the crack follow-up of the waterproofing sheets of this invention is good, the waterproofing sheets are not damaged and excellent waterproofing capacity can be assured even if cracks develop in the secondary coating cement concrete. Even if by any chance the crack width is large and damage of the waterproofing sheet occurs, because the other portions of the waterproofing sheet are a single entity with the secondary coating cement, water does not infiltrate into the gap between the waterproofing sheets and the secondary coating concrete; therefore, the industrial benefits are extremely great.
