Embodiment 1

[0036] Reference attached figure 1 , a greening structure of expressway mountain woodland, comprising a hardened layer 1 formed by pouring concrete on a slope surface and a greening component 2 arranged on the hardened layer 1 .

[0037] The greening component 2 includes several greening units 21 arranged along the inclination direction of the slope, and the greening units 21 are closely attached and arranged parallel to each other. The greening unit 21 includes a supporting frame 211 installed above the hardened layer 1 . In this embodiment, the supporting frame 211 is welded by a plurality of steel supporting columns, and a greening groove 212 is welded on the supporting frame 211 . The green groove 212 includes a bottom plate and side plates welded on both sides of the bottom plate. The bottom of the slope is provided with a drainage groove 3, and the rainwater flows along the greening groove 212, and flows into the drainage groove 3 from the greening groove 212, and is di...

Embodiment 2

[0045] Reference attached Figure 4 The only difference between this embodiment and the first embodiment is that the diameter of the water permeable hole 216 is much larger than the particle diameter of the activated carbon particles, and a filter screen 217 is installed in the water permeable hole 216, and the aperture of the filter screen 217 is smaller than the particle diameter of the activated carbon particles.

[0046] This can increase the drainage of the permeable hole 216 and improve the smoothness of the drainage. At the same time, through the setting of the filter screen 217, on the one hand, the larger impurities in the rainwater can be filtered, and the cleanliness of the rainwater has been improved. On the other hand, it can prevent The rainwater washes away the activated carbon particles, thereby increasing the temperature and ensuring a stable and good growth environment for green plants.

Abstract

The invention relates to the technical field of expressway greening, in particular to a mountain forest greening structure for an expressway. The mountain forest greening structure for the expresswaycomprises a hardened layer and a greening assembly, wherein the greening assembly comprises a plurality of greening units which are tightly arranged in the inclined direction of a slope, each greeningunit comprises a support frame mounted above the hardened layer, a greening tank is mounted on the support frame, baffle plates are mounted in the greening tank and divide the greening tank into multiple planting grids, the planting grids are filled with planting media, and a drainage channel is formed at the bottom of the slope. The hardened layer protects soil on the slope and prevents rainfallfrom scouring the slope and causing water and soil erosion; by means of the greening assembly, the greening area of the slope surface is increased, and the greening rate of two sides of the expressway is increased.

Description

technical field [0001] The invention relates to the technical field of expressway greening, in particular to a greening structure of expressway mountain forest land. Background technique [0002] With the continuous improvement of the economic level, the construction of expressways is booming. Expressways refer to "highways that can adapt to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, are exclusively used for high-speed driving in separate lanes, and all access and exit are controlled." Although countries have different names for expressways, they all refer to highways with more than 4 lanes, two-way separation, complete control of entrances and exits, and all interchanges. In addition, in many countries, direct arterial lines that partially control entrances and exits and not all use interchanges are also called expressways. As of 2013, my country has the longest expressway in the world, with 104,400 kilometers. [0003] Al...
