Description

A kind of slope ecological restoration structure of damaged mountain

technical field

The utility model relates to the technical field of ecological restoration of damaged mountain bodies, in particular to a slope ecological restoration structure of damaged mountain bodies.

Background technique

The acceleration of urban construction has led to a great increase in the demand for building stones. Many mountains with beautiful surroundings around cities have become quarries during urban construction. As a result, a large number of original mountains have been severely damaged. The ecological restoration of damaged mountains can help improve the The ecological environment of the damaged mountain is to avoid the increasingly serious ecological and environmental problems caused by the mining of the mountain. Therefore, it is urgent to find suitable ecological restoration measures for the damaged mountain.

The existing ecological restoration technologies for damaged mountains generally use soil backfill to fill the foundation pit formed by the damaged mountain, and then plant trees on the soil layer to fix the soil and lock water, but the soil that has just been backfilled is not stable enough. It is easy to be washed by rain and cause soil erosion. After soil loss, trees are difficult to survive, which makes it difficult to manage damaged mountains. Therefore, a new technical solution should be proposed to solve the above problems.

Utility model content

The purpose of the utility model is to provide an ecological restoration structure for the side slope of a damaged mountain body, which can manually fix the soil by setting up earth retaining means, so as to achieve the effect of preventing water and soil loss caused by rain erosion.

In the soil layer, trees are planted in the planting soil layer to fix the water and soil. In addition, in order to avoid rainwater erosion, a retaining block is set on the surface of the planting soil layer, and the anchor rod is driven into the building spoil layer to ensure the stability of the retaining block. It can also stabilize the soil and water and prevent soil erosion caused by rainwater erosion.

It is further preferred that: the surface of the planting soil layer is poured with concrete drainage ditches at intervals.

With the above structure, when it rains, the rainwater will easily scour the soil, resulting in soil loss. The setting of the drainage ditch can provide a collection place for the water flow, thereby preventing the water flow formed by the rainwater from scouring the soil.

It is further preferred that a drainage groove is formed on the surface of the earth retaining block, and the drainage grooves on both sides of the drainage ditch are communicated with the drainage ditch.

With the above structure, the arrangement of the drainage groove can increase the drainage performance of the entire surface, and the water flowing through the drainage groove can flow into the drainage ditch, thereby further draining the rainwater on the surface of the planting soil layer and preventing the soil from being washed away.

It is further preferred that turf is also planted on the planting soil layer.

With the above structure, on the one hand, the turf is a low-grade plant, and its vitality is relatively tenacious.

It is further preferred that a water reservoir is arranged at the bottom of the side slope, and the reservoir is communicated with each drainage ditch, and an irrigation system is arranged in the planting soil layer.

With the above structure, the water reservoir can be set up to collect rainwater, and when it does not rain, the collected rainwater can be irrigated into the planting soil layer by the irrigation system, so as to irrigate the plants and avoid water shortage of the plants.

Further preferably, the watering system includes a water pump with a water inlet communicating with the water reservoir, a water pipe communicating with the water outlet of the water pump, and a watering head connected to the end of the water pipe away from the water pump.

With the above structure, the water pump is connected to the power supply through the line, and the water pump can be started, and the water pump in the reservoir can be pumped into the water pipe and sprayed out from the watering head, thereby watering the plants.

It is further preferred that the water pump is fixed to the side of the reservoir by bolts, and the outer casing of the water pump is provided with a protective cover.

With the above structure, the water pump is fixed by bolts, the structure is simple, and the stability can be ensured, and the arrangement of the protective cover can protect the water pump.

It is further preferred that the watering head is rotatably connected to the water pipe, and the watering head is provided with several water outlets that rotate in the same direction.

With the above structure, the watering head is rotatably connected to the water pipe, and due to the rotating arrangement of the water outlet of the watering head, when the water flows out, it can impact the water outlet and make the watering head rotate, thereby making the watering more uniform and larger.

To sum up, the utility model has the following beneficial effects:

1. The construction spoil layer is used as the bottom layer of the foundation pit, on the one hand, it can ensure the stability of the bottom soil of the foundation pit, and on the other hand, it can solve the urban spoil problem to a certain extent, and then cover the construction spoil layer with soil as the planting soil layer , Plant trees in the planting soil layer to fix the soil and water. In addition, in order to avoid rainwater erosion, a retaining block is installed on the surface of the planting soil layer, and the anchor rod is driven into the building spoil layer, which can ensure the stability of the retaining block and can also It has the effect of stabilizing soil and water, preventing soil erosion caused by rain erosion;

2. The setting of the reservoir can collect rainwater. When it does not rain, the collected rainwater can be irrigated into the planting soil layer by the irrigation system, so as to water the plants and avoid the lack of water for the plants.
