Description

Ecological protection structure of side natural high slope of pavement

Technical Field

The utility model relates to a slope processing technology field, concretely relates to other natural high slope ecological protection structure of pavement.

Background

The side slope is a slope formed naturally or artificially, is one of the most basic geological environments in human engineering activities, and is also the most common engineering form in engineering construction. No matter the slope is a natural slope or an artificial slope, the geological disasters such as debris flow, landslide, progressive collapse and the like can occur under the external force action of rain wash, down-slope water flow, weathering action or earthquake and the like.

For the naturally stable high slope beside the urban sidewalk, the naturally stable high slope is a slope which is higher than 15 m and is formed naturally or formed by construction and excavation, the self rock-soil structure is relatively stable, the probability of geological disasters is low, and the slope surface does not need to be reinforced and protected. However, the condition that surface sand falls off can occur under the action of long-term weathering or rainwater in rock soil of the side slope or above, so that normal passing of pedestrians is affected and sidewalk pollution is caused. Meanwhile, under the condition of large rainwater quantity, rainwater flows down the slope and flows down to the sidewalk, and the influence on the sidewalk is more serious along with the pollution and erosion of sandy soil.

Therefore, how to effectively prevent rainwater and sandy soil of the natural high slope beside the sidewalk from flowing into the sidewalk is a technical problem to be solved urgently.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a natural high slope ecological protection structure beside a sidewalk is characterized in that a groove along the moving direction of the sidewalk is arranged between a sidewalk 1 and a slope toe of a natural high slope 2, the sidewalk and the natural high slope are respectively arranged on two sides of the groove, a short retaining wall 3 is arranged on one side of the groove close to the sidewalk 1 to separate the sidewalk from the groove, the lower end of the short retaining wall 3 is arranged at the bottom of the groove and is flush with the bottom of the groove, the upper end of the short retaining wall is higher than the sidewalk, a water filtering layer 4 is arranged at the bottom of the groove, a geotextile layer 5 is arranged on the upper surface of the; a planting soil layer 6 is arranged on the upper surface of the geotextile layer 5, and the upper surface of the planting soil layer 6 is lower than the upper surface of the short retaining wall or is flush with the upper surface of the retaining wall; the vegetation 8 is planted on the surface of the planting soil layer.

The geotextile, also known as geotextile, is a water permeable geosynthetic material formed from synthetic fibers by needling or weaving. The vegetation is shrub or small flower tree, such as pomegranate, ligustrum japonicum, tiger creeper, etc. In the embodiment, the retaining wall is built by red bricks, the short retaining wall is 600 mm higher than the surface of the sidewalk, the thickness of the retaining wall is 200 mm, and the upper surface of the planting soil layer is flush with the upper surface of the short retaining wall.

Thus, after the rainwater and the sandy soil fall into the planting soil layer, the vegetation can effectively keep the stability of the water and the soil to a certain degree, the excessive rainwater flows through the geotextile layer through the planting soil layer and enters the water filtering layer, the rainwater enters the water filtering layer through the geotextile layer, and the sandy soil is intercepted by the geotextile and stays on the surface of the geotextile. Meanwhile, the planted vegetation forms a green belt which can not only beautify the municipal environment, but also can absorb the silt generated by natural weathering.

And waterproof mortar 7 is arranged on one side surface of the short retaining wall opposite to the natural high slope. The waterproof mortar is prepared from cement and polymer dispersoid serving as a cementing material and sand, and can further prevent rainwater on the side of a natural high slope from permeating into a sidewalk to cause pollution through a retaining wall and protect a short retaining wall so as to prevent the service life of the rainwater from being influenced after the rainwater is in long-term contact with the short retaining wall. The surface of the retaining wall on one side of the sidewalk and the upper surface of the retaining wall can be subjected to surface finishing treatment according to design requirements, such as surface decorating material pasting, paint brushing and the like to beautify visible surfaces.

The water filtering layer is formed by piling pebbles with the particle size of 20-30 mm. The pebbles are in the shape of water chestnuts, have good surface area, high mechanical strength and no impurities, are good water filtering layer materials, and can play a good supporting role on a planting soil layer. Various kinds of pebbles are suitable for the structure, and local cheap kinds can be selected. The drainage layer in this example had a thickness of 200 mm.

The width of the groove is not less than 600 mm, and the thickness of the retaining wall in the embodiment is 200 mm, so that the width of the water filtering layer is not less than 400 mm.

Be equipped with the drain pipe (not shown in the figure, set up according to actual municipal rainwater pipe net position) between drainage layer and municipal rainwater pipe net, drain pipe one end is passed the barricade and is located in the drainage layer, and the other end is connected with municipal rainwater pipe net. The number of the drain pipes is a plurality, and all the drain pipes are arranged at intervals along the length direction of the sidewalk. Therefore, accumulated water in the water filtering layer can be directly drained to the municipal rainwater pipe network through the drainage pipe, and timely and effective drainage is achieved.

Finally, it should be noted that the above-mentioned embodiments of the present invention are only examples for illustrating the present invention, and are not limitations to the embodiments of the present invention. Variations and modifications in other variations will occur to those skilled in the art upon reading the foregoing description. Not all embodiments are exhaustive. All obvious changes or variations which are introduced by the technical solution of the present invention are still within the scope of the present invention.
