The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1, the embodiment provides an ecological slope protection system, which includes a retaining wall 1 and a drainage ditch 2, wherein the retaining wall 1 is arranged at the toe of a side slope, the retaining wall 1 extends upwards in an inclined manner towards the side slope, and a gap between the retaining wall 1 and the side slope is filled with backfill soil 3; the escape canal 2 is arranged on one side of the retaining wall 1 deviating from the side slope.

In the ecological slope protection system provided by the embodiment, the backfill 3 is filled between the retaining wall 1 and the side slope, so that the retaining wall 1 indirectly supports the side slope, and meanwhile, the retaining wall 1 is obliquely arranged, so that the bearing capacity of the retaining wall 1 is improved; the drainage to rivers has been promoted in setting up of escape canal 2, and consequently, the ecological bank protection system that this embodiment provided has improved the drainage effect to the side slope, and improves the bearing capacity of barricade 1 to the improvement is to the protective effect of side slope.

Specifically, the drainage ditch 2 comprises a side wall 21 and a bottom plate 22 connected to the side wall 21, one side of the bottom plate 22 away from the side wall 21 is connected to the retaining wall 1, and the side wall 21, the bottom plate 22 and the retaining wall 1 enclose a drainage channel of the drainage ditch 2. The arrangement enables the retaining wall 1 to support the side slope and serve as a side wall of the drainage channel, and the diversion effect is achieved on water flow.

Alternatively, the two side walls of the bottom plate 22 and the retaining wall 1 contacting each other have the same inclination angle, and are completely attached to each other, so that the water flow is prevented from leaking through the gap between the two side walls.

Specifically, the upper surface of the bottom plate 22 extends obliquely downward from the side connected to the retaining wall 1 to the side connected to the side wall 21. The device is favorable for water flow collection, promotes the flow of water flow, is favorable for relieving the drainage problem of the heavy rainfall ditch, and washes away impurities such as gravel, pebbles, dead leaves and the like in the ditch.

Specifically, plants are planted in the backfill soil 3. As shown in fig. 1, trees 7, preferably deep-rooted plants such as trees, shrubs, vines and the like, are planted on the surface layer of the backfill soil 3 at intervals, and can effectively play a role in soil stabilization and slope protection; meanwhile, flowers and plants 8 are planted on the surface layer of the backfill soil 3, so that the effects of beauty and ecological greening are achieved. The ecological slope protection system that this embodiment provided, through barricade 1, escape canal 2 and ecological environmental protection's effective combination, increased the displacement, realized escape canal 2 unblock, still satisfy the environmental protection requirement simultaneously, be particularly useful for the side slope protection in this kind of tropical rain forest climate area of similar Tibet ink doff county.

Specifically, a drain pipe 4 is arranged in the retaining wall 1, the water inlet end of the drain pipe 4 extends to the side wall of the retaining wall 1 facing the backfill soil 3, and the water outlet end of the drain pipe 4 extends to the side wall of the retaining wall 1 facing the drainage ditch 2. The water discharge pipe 4 is beneficial to discharging the water seepage in the side slope and the backfill soil 3. The seepage water in the side slope and the backfill soil 3 is guided into a drainage channel of the drainage ditch 2 through a drainage pipe 4, so that the water flow is collected and discharged.

More specifically, the drain pipe 4 extends obliquely downward from the water inlet end toward the water outlet end. The inclined downward arrangement is more beneficial to the discharge of water flow. A plurality of water discharge pipes 4 can be arranged in the retaining wall 1, the specific number of the water discharge pipes 4 is determined according to the height of the retaining wall 1, and when the retaining wall 1 exceeds 2m, two layers of water discharge pipes 4 are uniformly arranged in principle, and the quincunx is arranged at intervals; the drain pipe 4 is mostly made of PVC pipe.

Specifically, the end of the water inlet end of the water discharge pipe 4 is provided with an inverted filter layer 5. The reverse filtering layer 5 plays a role in filtering, and the soil body is prevented from being taken away by the downward seepage water when the downward seepage water flows out, so that the drainage pipe 4 can be prevented from being blocked by impurities and the flowing soil can be prevented from occurring. The water inlet end of the water discharge pipe 4 is wrapped by geotextile (soil filtration and water discharge), and the reverse filter layer 5 is usually composed of large stones, medium stones and small stones, so that the gaps are reduced layer by layer.

More specifically, the water inlet end of the drain pipe 4 is located at the lowest position of the backfill soil 3. Because the lower infiltration in the backfill soil 3 can collect the lower extreme, the end of intaking sets up in the lower extreme, can improve the discharge amount of infiltration down.

Optionally, a concrete shoulder 6 is disposed above the side wall 21, and one side of the concrete shoulder 6 facing away from the bottom plate 22 abuts against the road. The concrete road shoulder 6 has higher strength, and the concrete road shoulder 6 is propped against the road, and the main function is to bear the lateral pressure of the road, so that a solid foundation can be provided when the safety waveform guardrail is used, and the structural stability of the road and the slope protection system is improved.

Optionally, in other embodiments, the side walls 21 and the bottom plate 22 may be made of concrete, the concrete shoulder 6, the side walls 21 and the bottom plate 22 may be integrally formed by casting, or the bottom plate 22, the side walls 21 and the concrete shoulder 6 may be sequentially cast from bottom to top.

In this embodiment, both the side walls 21 and the bottom plate 22 are constructed of masonry rubble. The grouted rubble is poured on the basis of ensuring the drainage function, and the investment of cost can be reduced. During construction, the bottom plate 22 is firstly built from bottom to top, then the side walls 21 are built, and finally the concrete road shoulder 6 is poured. The surfaces of the side wall 21 and the bottom plate 22 constructed by the mortar rubble are rough, so that the inner surfaces of the side wall 21 and the bottom plate 22 need to be subjected to mortar plastering to form a smooth surface, and drainage is facilitated.

The side of the retaining wall 1 against the backfill soil 3 is a back side, the side facing the drainage ditch 2 is a front side, and the slope ratio of the front side to the back side can be the same or different. As shown in fig. 1, the slope ratio of the front surface and the back surface is different, and the slope ratio of the back surface is greater than that of the front surface, and in this case, the thickness of the bottom of the retaining wall 1 is greater than that of the top. As shown in fig. 2, the slope ratio of the front and back surfaces is the same, and the thickness of the whole retaining wall 1 is uniform. The height of the retaining wall 1 is not too high, and in the embodiment, the height of the retaining wall 1 is below 4 m.

Specifically, the thickness range of the side wall 21 and the bottom plate 22 of the drainage ditch 2 is 10cm-35cm, and generally, the construction is mostly carried out by 20cm-25 cm; the range of slope ratios of the upper surface of the bottom plate 22 is taken as: 2 to 15 percent, generally about 5 percent, which greatly affects the construction and cannot accelerate the drainage effect when the size is too small.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
