Abstract
The utility model discloses a cold region tunnel grid-shaped thermal insulation structure separated from a wall. If a thermal insulation structure with an air medium layer and polyurethane combined is adopted in a tunnel, convective heat exchange can exist in an air thermal insulation layer and affect the thermal insulation effect when the thermal insulation layer is damaged and leaks air. According to the outermost layer of the cold region tunnel grid-shaped thermal insulation structure separated from the wall, second lining concrete is arranged on the outermost layer, a grid is attached to the inner wall, a thermal insulation plate is laid on the inner layer of the grid, and a fireproof plate is laid on the inner wall of the thermal insulation plate; U-type components are fixed in the second lining concrete through expansion bolts, and the grid is connected to the U-type components in a lap joint mode and fixed through tapping screws; the U-type components penetrate through the thermal insulation plate on the inner layer of the grid, and at joints of the thermal insulation plate, light steel keels arranged in a pressed mode are fixed to the U-type components through tapping screws; the fireproof plate laid on the inner wall of the thermal insulation plate is fixed to the light steel keels through tapping screws. An air layer and a thermal insulation layer which are formed by the grid achieve the thermal insulation effect together, and therefore the problem that the thermal insulation effect is affected because the polyurethane thermal insulation layer is partially damaged and leaks the air is solved.
Description
Technical field
the utility model belongs to tunnel construction technology field, is specifically related to a kind of tunnel in cold area grid-like from wall type insulation construction.
Background technology
During tunnel in cold area operation with seasonal variations, in hole, temperature can make tunnel lining and country rock behind stand freeze thawing circulation, and the frost-heave force repeated action of generation is in lining cutting, and after lining concrete experience freeze thawing circulation, its durability reduces, affect the safety of liner structure, thereby cause freezing damage in tunnel.
Build both at home and abroad and at the tunnel in cold area of building, extensively adopt the mode of laying thermal insulation layer on tunnel lining structure to alleviate the adverse effect of freeze thawing circulation to liner structure.Tunnel insulation isolation layer paving mode has four kinds: surface laying, interlayer are laid, from wall, laid and double-deck laying.For reaching the uncongealable requirement in tunnel, according to calculating, required insulation layer thickness is often thicker, consider that air is best thermal insulation medium, for reducing construction costs, taked the insulation construction of air dielectric layer and polyurethane (or poly-phenolic aldehyde) combination, between insulation layer and two lining inner surfaces, leave one deck sealing air layer, form from wall type insulation layer, which heat insulation effect is better than surperficial paving mode.But this kind is traditional from wall type insulation construction, when damaged gas leakage appears in insulation layer, can make to have heat convection in air heat insulating layer, by the effect of heat insulation of the whole air heat insulating layer of impact, cause the heat insulation effect of insulation construction to reduce.
Summary of the invention
It is grid-like from wall type insulation construction that the purpose of this utility model is to provide a kind of tunnel in cold area, by PE plastic grill grid, tradition is separated into block of cells from wall type air layer, avoid cross-ventilation heat exchange, solved the defect of traditional effect of heat insulation variation of bringing because local damage leaks gas from wall type insulation construction.
The technical scheme that the utility model adopts is:
Grid-like from a wall type insulation construction, outermost layer is two lining concrete, it is characterized in that:
Two lining concrete inner walls paste grid grid, and grid grid internal layer is laid warming plate, and warming plate inwall is laid PLASTIC LAMINATED.
In two lining concrete, by expansion bolt, fix U-shaped member, grid grid is overlapped on U-shaped member and by self threading pin and fixes;
U-shaped member is through the warming plate of grid grid internal layer, and the lightgage steel joist that warming plate connecting sewing place is installed with is fixed on U-shaped member by self threading pin.
The PLASTIC LAMINATED that warming plate inwall is laid is fixed on lightgage steel joist by self threading pin.
PLASTIC LAMINATED jet surface fireproof paint levelling PLASTIC LAMINATED connecting sewing and fixed point.
Described grid grid is PE plastic grill grid.
Two described lining concrete and the seam of grid lattice are filled out and are established epoxide-resin glue.
The utlity model has following advantage:
A kind of tunnel in cold area that the utility model provides is grid-like from wall type insulation construction, and the air layer and the insulating that mainly by grid grid, form are realized heat insulating effect jointly.Air layer is good thermal insulation medium, PE plastic grill grid is separated into block of cells by tradition from wall type air layer, avoided cross-ventilation heat exchange, compare from wall type insulation construction with tradition, eliminated the impact of polyurethane (or poly-phenolic aldehyde) insulation layer local damage gas leakage on whole air heat insulating layer effect of heat insulation.The utility model is simple in structure, laying construction is easy, be easy to replacing safeguards, does not substantially increase cost, does not increase constructing tunnel difficulty, has effectively improved the antifreezing heat insulation effect of tunnel in cold area.
