The invention belongs to anti-freeze damage facilities for road and railway subgrades, in particular to a high-strength anti-freeze damage water-proof cushion, in which epoxy resin and curing agent (4) are used to bond high-strength fiber materials ( 2.5) Form the anti-freeze damage water-proof cushion, make the water-proof cushion into a groove shape with outer slopes on both sides and a horizontal bottom, and place the bottom of the anti-freeze damage water-proof cushion horizontally on the maximum freezing depth line (1) , the outer high-strength fiber material (2) in the shape of a slope groove is in contact with the side frozen soil (8), and the inner layer of high-strength fiber material (5) is provided with artificial fill (7), and above the artificial fill (7) is an embankment Or the building foundation (6), the high-strength anti-freeze damage water-proof cushion overcomes the coarse-grained material and is applicable to a wider range of soil quality, and the construction is not affected by the region and the environment; it has high strength, good compression and crack resistance, and good aging resistance , adapt to a wide range of ambient temperature, stable quality, and long service life of the project.
Description
Technical field
The invention belongs to the frost damage prevention facility of highway, railway bed, particularly a kind of high intensity freezing damage prevention waterproof cushion layer.
Background technology
Exist countless capillary tubies in the subgrade soils, underground water mainly rises to roadbed inside by the capillary tube in the roadbed, arrive winter, when the atmosphere subzero temperature imports into underground, Free water in the face of land is the glaciation crystal at first, continuation decline along with temperature, the outermost layer of water of hydration also begins to freeze, and ice crystal is enlarged gradually, and form ice band in soil layer, the freezing back of moisture volume will increase by 9%, the soil body is swelled along with expanding, frost heaving occurs, particulate is many more in the soil, the capillary tube that forms is just many more, and is also big more to the influence of roadbed.Therefore, often adopt methods such as frost heave soil in the non-frost heave material substitution of coarse granules such as sand gravel, medium coarse sand or the aeolian sand ground, forced ramming reinforcing foundation soil and film isolation foundation soil to prevent and treat the foundation soil body freeze injury.But, change made ground base indigenous method for coarse granule, " anti-pollution " of grit bed course is though problem and material-taking on-site problem have hindered its suitable great soil group of development forced ramming reinforcing foundation soil in engineering is used extensive, equipment is simple, easy construction, economical with materials, expense is lower, and it is used and but is subjected to engineering ambient influnence of living in; Film is isolated the filled ground method can well prevent that underground water from infiltrating roadbed, but difficulty of construction is bigger, and film very easily breaks so that leak because of the construction error causes.In addition, this water proof mode has only intercepted the supply at water source, below, but can not prevent the infiltration of side direction water body.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide simple, the suitable soil property scope of a kind of construction wide, good seepage-proof property, the high intensity freezing damage prevention waterproof cushion layer of good endurance.
The technical scheme that technical solution problem of the present invention adopts is: the characteristics of high intensity freezing damage prevention waterproof cushion layer are to form freezing damage prevention waterproof cushion layer with epoxy resin and curing compound bonding high fiber strength strains on the compound geotechnological film two sides, it is the flare inclined-plane that the water proof bed course is made both sides, the groove shaped of bottom level, the freezing damage prevention waterproof cushion layer bottom level places maximum to freeze deep layer line place, the outer high fiber strength strains of inclined plane groove shape contacts with side frozen soil, establish the artificial earth fill in the middle of the internal layer high fiber strength strains, the artificial earth fill top is embankment or building foundation.
The invention has the beneficial effects as follows: high intensity freezing damage prevention waterproof cushion layer has overcome the region restriction that coarse granule material exchange filling method is drawn materials, and it is wideer to be suitable for the soil property scope, and construction is not subjected to region and ambient influnence; Possesses the dual-use function that prevents body of groundwater supply and the infiltration of side direction water source; The intensity height, resistance to compression and cracking resistance are good, and ageing-resistant performance is good, and the temperature range that conforms is wide, steady quality, engineering long service life.
Description of drawings
Below in conjunction with accompanying drawing with embodiment specific requirement explanation.
Fig. 1 is the high intensity freezing damage prevention waterproof cushion layer structure chart.
Among the figure, the maximum frost line of 1-; The outer high fiber strength strains of 2-; The 3-compound geotechnological film; 4-epoxy resin and curing compound; 5-internal layer high fiber strength strains; 6-embankment or building foundation; The 7-artificial earth fill; 8-frozen soil;
The specific embodiment
Embodiment, with reference to accompanying drawing 1, high intensity freezing damage prevention waterproof cushion layer is earlier epoxy resin and curing compound 4 to be stirred together, be applied in after stirring on two sides of compound geotechnological film 3, be bonded on two sides of compound geotechnological film 3 high strength fibre is staggered, make the antifreeze water proof bed course of high strength.Key dimension and the general condition of engineering geology required according to the job site, cut out the frost heave soil body of maximum frost line more than 1 by demand, make its shallow foundation that forms safe gradient hole, to cheat smooth the rolling of the wall and the end, hole, guarantee that the hole wall and the end, hole have certain compactness and do not have rubble, the antifreeze water proof bed course that to make afterwards is laid on the end, hole open and flatly, form band inclined-plane, both sides, the groove shaped of bottom level, antifreeze water proof bed course and frozen soil 8 contact surfaces are outer high fiber strength strains 2, the foundation soil that will dig out before will constructing in the groove of internal layer high fiber strength strains 5 is as artificial earth fill's 7 backfills, and artificial earth fill 7 will transfer to optimum moisture content.Equidistant with antifreeze water proof bed course edge or less than the artificial earth fill 7 of antifreeze water proof bed course edge above can build embankment or building foundation 6.
Claims (1)
1. high intensity freezing damage prevention waterproof cushion layer, it is characterized in that on compound geotechnological film (3) two sides with epoxy resin and curing compound (4) bonding high fiber strength strains (2,5) form freezing damage prevention waterproof cushion layer, it is the flare inclined-plane that the water proof bed course is made both sides, the groove shaped of bottom level, the freezing damage prevention waterproof cushion layer bottom level places maximum to freeze deep layer line (1) and locates, the outer high fiber strength strains (2) of inclined plane groove shape contacts with side frozen soil (8), establish artificial earth fill (7) in the middle of the internal layer high fiber strength strains (5), artificial earth fill (7) top is embankment or building foundation (6).
