Description
Technical field
The utility model relates to side slope or slope stability technology, specifically, relates to the rock-steady structure of a kind of cold district different kinds of roads side slope, house foundation side slope, natural side slope.
Background technology
At present, be used for reducing the engineering of cold district slope soil frozen swell and melt settlement amount, a kind of is to adopt the larger non-frost heave coarse aggregate of transmission coefficient all to replace the original swelling soil of side slope, another kind is to adopt non-cold district slope treatment method, namely adopts the retaining structures such as antislide pile or retaining wall to prop up gear.
Adopt non-frost heave coarse aggregate can make construction costs increase decades of times, long construction period not only, and have potential safety hazard.Adopt the retaining structure cost also very high, more seriously can not fundamentally reduce cold district slope soil frozen swell and melt settlement amount, be easy to form the vicious circle of " every annual overhaul, annual bad ", not only cause larger economic loss, and left larger potential safety hazard.
The utility model content
To be solved in the utility model is the technical problem of cold district's side slope freezing up thaw collapse disease, and a kind of insulation construction that reduces cold district slope soil frozen swell and melt settlement amount is provided, and can reduce the depth of frost penetration and the frozen swell and melt settlement amount of cold district side slope, and construction costs is low simultaneously.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of insulation construction that reduces cold district slope soil frozen swell and melt settlement amount, the side slope bottom is provided with slope toe wall, described slope toe wall bottom surface is provided with bottom holding plates, described slope toe wall sidewall is provided with the sidewall warming plate, in the above 3 ~ 5m scope of described slope toe wall, 0.4 ~ 0.6m depth is provided with domatic warming plate below side slope surface, described bottom holding plates, described sidewall warming plate and described domatic warming plate are bonding by EPS plate to be that warming plate is whole, described warming plate whole installation is in the medium coarse sand bed course, and described domatic warming plate top is provided with the surface and is not less than side slope surface, the warming plate that the bottom surface is deeper than described medium coarse sand bed course protects the top.
Described slope toe wall is sheet stone concrete slope toe wall, rubble concrete slope toe wall or riprap concrete slope toe wall.
Described domatic warming plate is arranged at the following 0.5m of side slope surface place.
The beneficial effects of the utility model are:
(1) the utility model along slope toe wall bottom, sidewall and the domatic laying warming plate of a segment distance more than the slope toe wall, firm with the EPS plate bonding between the warming plate, utilize the characteristic of warming plate low thermal conductivity, effectively stop the atmosphere cold energy to be inputted in the slope soil, thereby reduce the depth of frost penetration and the frozen swell and melt settlement amount of side slope.
(2) the utility model arranges warming plate at the warming plate top and protects the top; warming plate protects the top and closely is connected with concrete with warming plate; can prevent that snow melt and atmospheric precipitation from entering to be seeped in warming plate bottom and the slope soil; can strengthen heat insulation effect; and play the effect that reduces the slope soil moisture content, also warming plate is played a protective role simultaneously.
(3) the utility model arranges slope toe wall in the side slope bottom, can strengthen the stability of side slope, and warming plate is played a protective role, and prolongs the life-span of warming plate.
Description of drawings
Fig. 1 is the representative side section view of insulation construction provided by the utility model;
Fig. 2 is the table floor map of insulation construction provided by the utility model.
Among the figure: 1, the medium coarse sand bed course; 2, warming plate is whole; 21, bottom holding plates; 22, the sidewall warming plate; 23, domatic warming plate; 3, warming plate protects the top; 4, the domatic soil body; 5, slope toe wall.
The specific embodiment
For further understanding content of the present utility model, characteristics and effect, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
As depicted in figs. 1 and 2, the utility model discloses a kind of insulation construction that reduces cold district slope soil frozen swell and melt settlement amount, its structure is protected top 3 by slope toe wall 5, bottom holding plates 21, sidewall warming plate 22, domatic warming plate 23, medium coarse sand bed course 1 and warming plate successively and is consisted of from toe to domatic.
Slope toe wall 5 is arranged at the side slope bottom, specifically can be sheet stone concrete slope toe wall, rubble concrete slope toe wall or riprap concrete slope toe wall.
Warming plate integral body 2 is made by heat insulating material general in the Foundation Design, comprises bottom holding plates 21, sidewall warming plate 22 and domatic warming plate 23 3 parts.Wherein, bottom holding plates 21 is laid on the bottom surface of slope toe wall 5, and sidewall warming plate 22 is laid on the sidewall of slope toe wall 5, domatic warming plate 23 slope toe wall more than 5 along in the side slope 5m scope, be laid on the following 0.5m depth location of side slope surface.Bottom holding plates 21, sidewall warming plate 22 and domatic warming plate 23 are firm by the EPS plate adhesion each other.
