The specific embodiment
For further understanding content of the present invention, feature and effect, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, the invention discloses a kind ofly for preventing and treating the robust structure of cold district's side slope freeze thawing slump, mainly by arched framework 1, gutter 2 and insulation construction 3, formed.
Side slope surface is equipped with arched framework 1, and arched framework 1 comprises between 11, the two groups of adjacent arch rings 11 of arch ring that divide into groups to arrange and connecting with supporting gutter 12.
According to slope engineering geological conditions, slope angle, high, the domatic area in slope, the inherent slope soil of arch ring 11 4 surfaces of arched framework 1 are provided with a plurality of gutters 2.Gutter 2, according to rectangular array or quincunx arranged in arrays, forms certain level interval and vertical spacing between tube and tube, level interval is generally within the scope of 1.5～2.2m, and vertical spacing is generally within the scope of 1.1～1.5m.Gutter 2 level of answering is inserted slope soil 4 surfaces, or outer end inserts slope soil 4 surfaces with 0～5 ° of inclination angle downwards, and gutter 2 need expose slope soil 4 surfaces, and the length of exposing is generally 10～30cm.Gutter 2 can be selected PE gutter, PVC gutter or steel gutter.
As shown in Figure 3, be drilled with the drain hole 21 of several minor diameters on gutter 2, the diameter of drain hole 21 is determined concrete numerical value according to slope soil water content, is generally 5～8mm.Drain hole 21 arranging on gutter 2 is also according to rectangular array or quincunx arranged in arrays.According to certain level and the vertical spacing gutter 2 of arranging, gutter 2 is provided with the drain hole 21 of arranging according to certain rules, underground water that can white-out slope soil, thus reduce groundwater table and the side slope moisture content of side slope.
As shown in Figure 4, the outer wall of gutter 2, and the end that gutter 2 stretches in slope soil 4 is enclosed with close order gauze 22.Close order gauze 22 is provided with 1～5 layer, and the order number of close order gauze 22 be take 100～150 orders as good.Close order gauze 22 can prevent that the fine grained soils in side slope runs off from gutter 2 and slope soil 4 holes that cause increase and strength decreaseds.
In addition, side slope bottom is arranged at slope toe wall 5, and slope toe wall 5 can be specifically sheet stone concrete slope toe wall, rubble concrete slope toe wall or riprap concrete slope toe wall.Slope toe wall 5 can strengthen the stability of side slope, and warming plate is played a protective role, and extends the life-span of warming plate.
Insulation construction 3 comprises bottom holding plates 31, sidewall warming plate 32 and domatic warming plate 33 3 parts.Wherein, bottom holding plates 31 is laid on the bottom surface of slope toe wall 5, and sidewall warming plate 32 is laid on the sidewall of slope toe wall 5, and domatic warming plate 33 more than 5 within the scope of surperficial 5m, is laid on the following 0.5m depth location of side slope surface along side slope at slope toe wall.Bottom holding plates 31, sidewall warming plate 32 and domatic warming plate 33 are firm by EPS plate adhesion each other, and bottom holding plates 31, sidewall warming plate 32 and the domatic soil body 4 of domatic warming plate 33 surface coverage.Utilize the characteristic of warming plate low thermal conductivity, can effectively stop atmosphere cold energy to be inputted in slope soil, thereby reduce the depth of frost penetration and the frozen swell and melt settlement amount of side slope.
Bottom holding plates 31, sidewall warming plate 32 and domatic warming plate 33 are all arranged in medium coarse sand bed course 34.Medium coarse sand bed course 34, on the one hand for domatic levelling, so that warming plate bottom surface construction environment is smooth, on the other hand also because its hypotonicity plays certain waterproof action, thereby is protected insulating plate structure.
