Abstract
The utility model relates to a saliva ice control structure which has the structural properties that insulation boards are laid below a slope crest earthfill, a slope and the top half of a drainage channel, wherein the insulation board and the slope are connected through an anchor rod; at the middle part of the drainage channel, a cushion layer is formed through geotextile and silver sand; at the top of the drainage channel, a surface permeable layer is formed through hexagonal hollow bricks and broken stones; and soil including grass seeds is placed in the slope hexagonal hollow bricks to form an ecological side slope. According to the saliva ice control structure, the insulation boards are laid below the slope crest earthfill, the slope and the top half of the drainage channel, phreatic water in the direction of upslope flows down along the inner side of the slope insulation boards, gathers in the drainage channel and then drains off through the drainage channel; and the surface water drains off through the surface permeable layer. The saliva ice control structure can ensure that underground drainage lines can not freeze completely in winter, thus avoiding saliva ice.
Description
Technical field
The utility model relates to a kind of cold district salivary flow ice and prevents and treats structure.The salivary flow ice control that is fit to cold district excavation works section is used.
Background technology
China has most of area to be in cold district.Cold district excavation works very easily forms side slope type salivary flow ice, jeopardizes building and traffic safety.The reason that this disaster forms is: excavation has blocked the underground water migration path, makes and originally flows out on side slope in underground flowing water flow, under the cold climate condition, has just formed side slope type salivary flow ice.
Traditional salivary flow ice Prevention Technique has: hidden pipe, french drain, catchwater, retaining ice wall, retaining ice dam etc.Researched and developed multi-outlet drainage system, insulation and collecting well and heat-insulating water outlet in recent years, all there is major defect in above-mentioned all these measures to preventing and treating side slope type salivary flow ice.The measure of backbreaking of a kind of in addition tradition is very big to environmental perturbation, and can not address this problem fully.China northeast, hills, northwest, mountain region many frontier defense road side slopes type salivary flow ice are very general, cause traffic obstacle, bring serious hidden danger to traffic safety, have also caused enormous economic loss simultaneously, and the conveying of army's desired substance simultaneously also is affected.Therefore, research is administered side slope type salivary flow ice for guaranteeing that highway communication is unimpeded, promoting that the economic construction of country is significant.
Summary of the invention
For reducing, prevent the harm of side slope type salivary flow ice, the purpose of the utility model is to provide a kind of salivary flow ice to prevent and treat structure.This structure is incubated processing to domatic, sloping top and gutter, and underground water flows into the gutter, and surface water is arranged to lower through permeable brick in top, gutter and macadam.Surface water is drained by different paths with underground water, has effectively improved temperature in the gutter, has prevented the generation of side slope type salivary flow ice.
The technical scheme that the utility model adopted is:
A kind of salivary flow ice is prevented and treated structure, is by warming plate, fill stratum, hexagon hollow brick, and gutter, cushion coat and face of land pervious layer are formed.Below the fill stratum of sloping top, domatic and middle and upper part, gutter lays warming plate; Warming plate is connected with domatic employing anchor pole; The middle part, gutter forms cushion coat by geotextiles and fine sand; The top, gutter forms face of land pervious layer by hexagon hollow brick and rubble, places the soil that contains grass seeds in the domatic hexagon hollow brick.
Above-mentioned warming plate is XPS or for EPS or for polyurethane sheet or for the foam concrete plate or for foam glass board.
The advantage of the utility model and the beneficial effect of generation are:
1, reduces slope excavation earthwork quantity, reach the effect of minimizing environmental perturbation.
2, the combination of permeable brick and insulation construction is used, and has guaranteed top drainage and has reduced the depth of frost penetration in the gutter
3, the domatic interior grass of planting of hexagon hollow brick of going up can reach the effect of beautifying the environment, and internally establishes and plays the reinforcement heat preservation effect when warming plate shields.
4, domatic carrying out significantly reduces the domatic depth of frost penetration of knowing clearly after the INSULATION DESIGN, avoided the freezing destruction that traditional mortar flag stone side slope causes and the generation of salivary flow ice disaster.
5, the use of the heat insulating material use amount that can reduce cubic metre of earth and reach the purpose of insulation.

The specific embodiment
Below, in conjunction with accompanying drawing the utility model is described further again:
As shown in Figure 1, a kind of salivary flow ice is prevented and treated structure, is by warming plate 2---and polyurethane sheet, fill stratum 1, hexagon hollow brick 3, gutter 6, cushion coat 5 and face of land pervious layer 4 are formed.Below sloping top fill stratum 1, domatic and 6 middle and upper parts, gutter lay polyurethane sheet, polyurethane sheet is connected with domatic employing anchor pole, and carries out the gap sealing waterproofing work.Bolt diameter 1.5cm.The polyurethane sheet thickness range is 6～15cm, coefficient of thermal conductivity 0.025W/m ℃.Stack piece stone in the gutter 6 and to 110cm, place geotextiles and fine sand formation cushion coat 5, and then lay the thick polyurethane sheet of one deck 10cm, then re-lay one deck rubble and hexagon hollow brick 3 formation face of land pervious layers 4 to drain surface water.At domatic laying hexagon hollow brick 3, fill out in the brick and put the soil that contains grass seeds at last, form ecological side slope.Hexagon hollow brick 3 length of side 30cm, thickness 30cm.
The diving of upward slope direction descends along domatic polyurethane sheet inboard, is pooled in the gutter 6, drains through gutter 6.The infiltration that face of land pervious layer 4 collection drainage surface water and domatic hexagon hollow brick 3 and domatic warming plate are 2.Slope top, domatic and top, gutter have been carried out rational insulation and have been handled, and have guaranteed that the underdrainage circuit can not take place to freeze fully in the winter time, prevent the generation of salivary flow ice.
Claims (2)
1. a salivary flow ice is prevented and treated structure; Be by warming plate (2), fill stratum (1), hexagon hollow brick (3); Gutter (6), cushion coat (5) and face of land pervious layer (4) are formed; It is characterized in that: fill stratum (1) below, domatic and middle and upper part, gutter (6) laying warming plate (2) on sloping top, warming plate (2) is connected with domatic employing anchor pole, and gutter (6) middle part forms cushion coat (5) by geotextiles and fine sand; Top, gutter (6) forms face of land pervious layer (4) by hexagon hollow brick (3) and rubble, places the soil that contains grass seeds in the domatic hexagon hollow brick (3).
