Problems solved by technology

These methods have played a huge role in the ecological protection of rocky slopes, but most of these methods are expensive, difficult to fix the base material, and the problem of water and soil loss has not been fundamentally solved. The rate is low, and regular watering and irrigation or manual maintenance are required. It is not really done once and for all, and its practical value is relatively low.
In addition, in the implementation process, the construction is difficult, the process is complicated, the greening effect is slow, and the advantages of combining the growth of vegetation with the characteristics of the rock mass have not been achieved.
[0003] In engineering, soil slopes can achieve ecological restoration in a short period of time through artificial protection and greening. There are many methods for supporting rock slopes, but the method of restoration and greening of rock slopes is currently seldom used, and the effect of regreening is poor.
In particular, the rocky slopes left over from engineering construction mostly have large water catchment areas, fast water flow, strong scouring force, and lack of soil conditions, nutrient conditions, and water conditions for plant growth, which will result in low plant survival rates and poor slope conditions. It is prone to collapse, landslide, and soil erosion, and the slope stability and ecological restoration are relatively difficult, and there are few comprehensive protection and greening technologies that can be used for rocky slopes

Embodiment 1

[0034] like Figure 1-5 Shown, a kind of device that is used for rocky slope vegetation greening and cyclic supply water nutrient, it comprises rocky slope 1, on described rocky slope 1 is anchored with anchor rod 2 by anchor shotcrete support, in anchor The anchor head part of the pole 2 is lengthened and built with a receiving platform 3, a water tank 4 is installed on the receiving platform 3, and a vegetation growth device 6 is installed on the top of the water tank 4; a water storage tank is installed on the top of the rock slope 1 8. The reservoir 8 is connected to the water tank 4 through a PVC hose 7, and a water valve 9 is installed on the PVC hose 7; a flare 5 is installed on the outer wall of the receiving platform 3.

[0035] Further, the anchor rods 2 are arranged in a quincunx arrangement or a rectangular arrangement on the rock slope 1 .

[0036] Further, the receiving platform 3 is formed by pouring concrete, and the upper surface of the receiving platform 3 i...

Embodiment 2

[0046] Any construction method for vegetation greening and circulating water and nutrient supply on rocky slopes is characterized in that it includes the following steps:

[0047] Step1: Clean up the debris on the surface of the rock slope 1, and drive the anchor rod 2 into the slope body by using the traditional anchor spraying support method, and build a receiving platform 3 at the anchor head after completion;

[0048] Step2: Place the designed water tank 4 on the adjacent receiving platform 3, install a reservoir 8 at the top of the slope after completion, and then use PVC hose 7 to connect all slope water tanks 4 to the reservoir 8;

[0049] Step3: Place the prefabricated vegetation growth device 6 on the surface of the slope water tank 4, and fix it on the surrounding supporting platform 3, and the whole device can start to work after completion.

Embodiment 3

[0051] According to the present invention, a device and method for greening rocky slope vegetation and circulating water and nutrient supply include the following steps:

[0052] 1. Clean up the dangerous rocks on the rocky slope 1, and carry out interception and drainage works on high slopes to reduce the erosion of the slope;

[0053] 2. The traditional slope anchoring and shotcreting support method is adopted for the slope body, in which the anchor rod 2 arranged in a plum blossom shape is installed in the slope, and the construction receiving platform 3 is added to the anchor head;

[0054] 3. Install the supply water tank 4 layer by layer from the bottom of the slope, and open holes above 1 / 3 of the height of the water tank, and use PVC rubber hose 7 to connect the set water tank 4 successively, and finally communicate with the reservoir 8 on the top of the slope. Form a complete set of water circulation system;

[0055] 4. Fix the prefabricated vegetation growth device ...

Abstract

The invention discloses a device for greening and circularly supplying moisture and nutriment for vegetation on a rock slope and a construction method. The device comprises the rock slope, wherein anchor rods are anchored on the rock slope through bolt-shotcrete supports, the anchor head position of each anchor rod is lengthened and provided with a bearing platform, the bearing platforms are provided with water tanks correspondingly, and vegetation growth devices are arranged at the tops of the water tanks correspondingly; a reservoir is arranged at the top of the rock slope, the reservoir isconnected with the water tanks through PVC hoses, and the PVC hoses are provided with water valves correspondingly; and flared openings are formed in the outer walls of the bearing platforms correspondingly. According to the construction method, lawn nursery strips are laid on the slope surface of the exposed rock slope by utilizing the climbing or hanging growth habits of climbing plants, meanwhile, the reservoir arranged at the top of the slope and the water tanks arranged on the slope surface form a water circulation system, and a nutrient circulating system is formed by the bearing platforms used for recycling the plant nutrients, so that on one hand, the slope can be rapidly covered and greened by the vegetation, and on the other hand, a long-term stable vegetation greening can be achieved.

Description

technical field [0001] The invention relates to the technical field of rock slope greening and ecological restoration, in particular to a device and construction method for rock slope vegetation greening and circulating water and nutrient supply. Background technique [0002] my country is a mountainous country. With the rapid development of national infrastructure construction in recent years, a large number of mountains are often excavated in the construction of roads, railways, mines, water conservancy and other construction projects, destroying the original vegetation surface and The native plant community causes a large number of exposed soil slopes and rocky slopes, leading to serious soil erosion, land desertification and ecological environment imbalance. A large number of exposed rock slopes not only bring safety hazards (secondary geological disasters such as collapses, landslides, and debris flows), but also seriously threaten the lives and property of surrounding r...
