Description

Ecological anchoring device with turbine rotational flow rain collecting and spiral permeability increasing functions Technical Field The invention relates to the technical field of ecological restoration, in particular to an ecological anchoring device with functions of turbine rotational flow rain collection and spiral permeation enhancement. Background In ecological slope engineering, soil fixation and slope protection (namely 'biological reinforcement') are performed by utilizing plant root systems, and the ecological slope engineering is a green sustainable treatment means. In order to solve the problem that the drought and water shortage of the side slope and the difficulty in deep binding of plant root systems are solved, the existing technical scheme generally adopts a diversion pipe or a rain collecting funnel device to guide water from the surface soil body to the deep soil body. However, the existing ecological diversion device has the following significant technical defects in actual complex field working conditions: (1) The water inlet is easy to be blocked, and the existing funnel or grid cover plate adopts a static water collecting mode. Under the storm brush, the sediment carried by the slope runoff is withered and rotten She Dengrong, which is easy to block the water inlet, so that the device is invalid. (2) Seedling hydraulic damage existing devices usually allow plants to grow directly from the rain collection port. The high-speed water flow converged by the rain collecting port can directly impact the fragile stem base of the seedling, so that the seedling is very easy to lodge, break and even drown, and the initial survival rate is seriously affected. (3) The water utilization rate is low, the existing straight pipe diversion structure has the advantages that water flow vertically and rapidly infiltrates under the action of gravity, most of the water is rapidly lost to deeper soil, a durable moist environment cannot be formed in a target soil layer, and lateral and deep development of a root system is difficult to effectively induce. (4) The initial instability is that the smooth pipe wall of the rigid pipe body cannot provide enough physical anchoring force at the initial stage, and the sliding is easy to occur along with the soil body.
