Description
Technical Field
The utility model belongs to the technical field of the side slope support technique and specifically relates to a have side slope packway of drainage and view afforestation irrigation concurrently.
Background
In recent years, with the higher and higher requirements of the country on environmental protection in engineering construction, the construction concept of the green water mountain gradually starts to be penetrated into the engineering construction. In the construction of hydroelectric engineering, the excavation of high side slopes is often involved, in order to guarantee the stability of the side slopes and the requirements of traffic in the construction period, the side slopes are required to be provided with the streets with different widths of 1-5 m, and the green plants are planted on the streets so as to meet the construction idea of green water hills. In order to ensure the safety and stability of the excavated side slope, a concrete supporting structure is often adopted for supporting and sealing, and drainage on the slope surface of the side slope is a major risk factor affecting the safety of the side slope during rainfall. No matter for soil or rock slopes, when a large amount of accumulated water is stored on the slope surface, the slope rock-soil body is gradually softened due to the infiltration of rainwater, the physical and mechanical parameters of the slope rock-soil body can be greatly reduced, and the slope instability is probably caused finally if the slope water body is not drained in time.
At present, a method for preventing water on the slope surface of the side slope is to excavate and build drainage ditches on the side slope horse way, and the drainage ditches on all levels of horse ways ensure that rainfall on the slope surface is timely drained out of the slope body. However, the traditional drainage technology often does not fully consider the risk that the drainage ditch is invalid because gravels, branches and leaves and the like are brought into the drainage ditch by rainwater and are blocked; in addition, the berm of the traditional side slope does not have a water storage function, and landscape vegetation death often occurs due to too much or too little rainwater on the side slope in berm greening design; landscape vegetation needs to be replaced after death, and the side slope is high, so that manual restoration is difficult and the cost is high.
In the prior art, chinese patent CN210857234U discloses a combined structure for slope platform greening and protection, which includes a drainage ditch inside the platform, a greening planting groove and a safety protection net. The inner side drainage ditch and the greening planting foundation slab are connected into a whole and are formed by cast-in-place of reinforced concrete; the inner and outer ditch walls of the inner side drainage ditch are equal in height, the rear side is backfilled by graded gravel soil, and an outward flowing water slope is formed on the surface; the greening planting groove is formed on the basis of the outer groove wall of the drainage groove and the low retaining wall, and soil is backfilled inside the greening planting groove for greening planting; the safety protection net is arranged at the edge of the side slope packway platform and consists of round steel pipe columns and a galvanized wire net. However, the upper part of the drainage ditch of the structure is not shielded, and the drainage ditch is easily blocked by sand, branches and leaves and the like washed by rainwater on the slope surface and fails. In addition, because the escape canal height and planting technique groove are equal in height and do not have the intercommunication, be difficult to guarantee to plant the inslot and plant by not washout when domatic large-scale rainfall takes place, and when need watering to planting the groove, be difficult to follow the interior water intaking of escape canal.
In the prior art, chinese patent CN209144959U discloses an ecological hedgerow groove based on high slope packway escape canal, including ordinary catch basin, be provided with the plastics baffle in the ordinary catch basin, the plastics baffle falls into left side escape canal and right side planting ditch two parts with ordinary catch basin, the middle part and the bottom fixedly connected with horizontal backup pad of plastics baffle, the lower part of plastics baffle is equipped with the infiltration hole, all lay on the trench wall side of right side planting ditch and the ditch bottom surface and be fixed with geotechnological cloth, the planting soil has been laid in the right side planting ditch, plant green plant in the planting soil. However, the upper part of the intercepting ditch of the structure is not shielded, and the intercepting ditch is easily blocked by sand, branches and leaves and the like washed by rainwater on the slope surface and fails. In addition, because the height of the intercepting ditch is equal to the height of the right planting ditch and is communicated with the intercepting ditch, when accumulated water appears in the intercepting ditch, the water level in the right planting ditch is higher due to the principle of a communicating device and no drainage channel of the planting ditch, the root system of the vegetation is soaked in water for a long time and dies, and the maintenance of the long-term landscape greening of the street is not favorable.
