The utility model provides a freeze proof landslide protection system that melts of anchor drainage formula channel side slope, belongs to channel designing technical field, including the drainage body of the channel slope body and the channel internal setting in slope, the internal portion in channel slope is on the cross section, and from top to bottom parallel arrangement has one or more circular pore, the inside drainage body that all is provided with of every circular pore, drainage body's one end is in the canal slope, and the other end is the export, and it is sloping that the exit end be the canal promptly. Drainage body comprises a polyethylene pipe and an anti - filter ruffle section of thick bamboo, and the polyethylene pipe is the long tubular structure, and the upper portion of the polyethylene tubular structure of managing and both sides all are provided with the round hole, an anti - filter ruffle section of thick bamboo is the drum structure, cup joints the outside at the polyethylene pipe. The utility model discloses realize side slope internal drainage, reduction slope back soil body ground water level with cutting soil saturation mode, simultaneously still can realize the reinforcement to the channel side slope soil body, and then the freeze thawing landslide destruction problem of fundamentally solution excavation channel, and the construction is simple, easily operation.

Description

A kind of anchoring drainage type channel side slopes freeze thawing resistance landslide guard system
Technical field
The utility model belongs to channel designing technical field, particularly relates to a kind of channel side slopes freeze thawing resistance landslide guard system.
Background technology
The northern area of China is the Northeast especially, is located in Frozen Area, and the channel side slopes in each irrigated area especially excavation channel side slopes ubiquity freeze thawing fall damage problem.
At present, mostly take anti-seepage heat preservation both at home and abroad, base soil changes and fill out, the close compacting of base soil pressure, optimize the measure such as lining structure type and solve freeze thawing Landslide Problems.Researched and proposed in addition and taked geotextile to carry out the scheme of reinforcement process to the whole channel side slopes soil body, though engineering actual motion effect is good, volume of earthwork is large, and cost is very high.
Therefore need badly in the middle of prior art and want a kind of novel technical scheme to solve this problem.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of anchoring drainage type channel side slopes freeze thawing resistance landslide guard system, while anchoring is carried out to the channel side slopes soil body, side slope internal drainage is realized to cut soil drench line mode, reduce soil body groundwater table behind slope, and then fundamentally solve the freeze thawing landslide destruction problem of excavation channel, and construction is simple, easy to operate.
A kind of anchoring drainage type channel side slopes freeze thawing resistance landslide guard system, it is characterized in that: comprise the water discharging body arranged in channel slope body and channel slope body, described channel slope body inner vertical cross section is arranged with one or more circular opening from top to bottom in parallel, and the angle of inclination of circular opening and horizontal plane is 0 ° ~ 1 °; Described each circular opening inside is provided with water discharging body, and one end of water discharging body is arrival end, and be arranged in the body of channel slope, the other end is the port of export, is arranged on the canal slope of channel slope body; Water discharging body is made up of vinyl tube and anti-filter sleeve, vinyl tube is long tubular structure, and the top of the tubular structure of vinyl tube and both sides are provided with circular hole, described anti-filter sleeve is cylindrical structure, is socketed in the outside of vinyl tube.
Described anti-filter sleeve is non-woven fabric back filter ruffle cylinder.
By above-mentioned design scheme, the utility model can bring following beneficial effect: a kind of anchoring drainage type channel side slopes freeze thawing resistance landslide guard system, while anchoring is carried out to the channel side slopes soil body, side slope internal drainage is realized to cut soil drench line mode, reduce soil body groundwater table behind slope, and then fundamentally solve the freeze thawing landslide destruction problem of excavation channel, and construction is simple, easy to operate.Non-woven fabric back filter ruffle cylinder is adopted to be arranged on the outside of vinyl tube, due to the water permeability of non-woven fabrics, both can ensure that the moisture in the body soil body of channel slope was pooled to vinyl tube tube chamber inside by the circular hole on non-woven fabrics and vinyon tube wall, vinyl tube can be prevented again by soil body silting, add the application life of water discharging body.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is a kind of anchoring drainage type of the utility model channel side slopes freeze thawing resistance landslide guard system integral installation structural representation.
Fig. 2 is a kind of anchoring drainage type of the utility model channel side slopes freeze thawing resistance landslide guard system water discharging body structural representation.
1-channel slope body, 2-water discharging body, 3-vinyl tube, 4-anti-filter sleeve, 5-circular hole in figure.
Detailed description of the invention
A kind of anchoring drainage type channel side slopes freeze thawing resistance landslide guard system, as shown in Figure 1, comprise the water discharging body 2 arranged in channel slope body 1 and channel slope body 1, described channel slope body 1 inner vertical cross section is arranged with one or more circular opening from top to bottom in parallel, and the angle of inclination of circular opening and horizontal plane is 0 ° ~ 1 °; Described each circular opening inside is provided with water discharging body 2, and one end of water discharging body 2 is arrival end, and be arranged in channel slope body 1, the other end is the port of export, is arranged on the canal slope of channel slope body 1.
As shown in Figure 2, water discharging body 2 is made up of vinyl tube 3 and anti-filter sleeve 4, and vinyl tube 3 is long tubular structure, and the top of the tubular structure of vinyl tube 3 and both sides are provided with circular hole 5, described anti-filter sleeve 4 is cylindrical structure, is socketed in the outside of vinyl tube 3.
Described anti-filter sleeve 4 is non-woven fabric back filter ruffle cylinder.
The operating principle of a kind of anchoring drainage type of the utility model channel side slopes freeze thawing resistance landslide guard system is,
After water discharging body is arranged into canal slope, because vinyl tube 3 top and both sides are provided with circular hole 5, and anti-filter sleeve 4 has water permeability, therefore the moisture in the soil body of canal slope can through the circular hole 5 on anti-filter sleeve 4 and vinyl tube 3, be pooled to bottom vinyl tube 3 tube chamber, be discharged to outside slope along short sword.And then groundwater table in reduction slope, drainage is carried out to the canal slope soil body, weakens the frost heave action to the soil body, improve the effective stress of the soil body.
In addition, when the canal slope soil body has slide downward trend, sliding mass will produce the active earth pressure of slide downward, owing to there is certain contact area between water discharging body 2 and the soil body, the intensity of the frictional resistance effect now played between water discharging body 2 and the soil body and vinyl tube 3 itself, balance that is the soil pressure of canal slope aspect lower slider will be kept with active earth pressure, be born by the water discharging body be arranged in the soil body.Therefore say that water discharging body has the double effects of draining and anchoring to the soil body.
