Description

A Sponge City Road Greening Belt Greenbelt System

technical field

The invention relates to the technical field of sponge cities, in particular to a green space system for road greening isolation belts in sponge cities.

Background technique

Sponge city refers to a city that, like a sponge, has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water when needed. and take advantage of it. The five basic elements of sponge city construction: slope, soil, groundwater, water supply and drainage facilities and plants. The composition of the urban green space system should include: garden plants, garden buildings, road sites, paving, garden bridges, rocks and water bodies, etc. It can be seen that the sponge city and the urban green space system are a coupling relationship. In the context of sponge city construction, the existing types of new green space technologies mainly include: green roofs, sunken green spaces, wet ponds, vegetation buffer strips, rainwater wetlands, etc. These green spaces are connected with the urban municipal system. The urban road green isolation belt plays a very important role in improving the road environment, ensuring driving safety, and beautifying the road landscape.

However, the urban road greening belt in today's market does not have a complete ecological network combined with urban surface water bodies and municipal systems, so it cannot form a sponge that can regulate and store water resources. If the current urban road greening belt encounters heavy rain, the rainwater will It will be too late to infiltrate into the ground, and water will be formed in the flower bed, which will easily lead to plant rot and affect plant growth, and because the soil layer is thin, the water storage capacity is limited during drought, and the water absorption and seepage of the green space are not obvious. Some plants are often transplanted in the community, especially the plant of camphor, which often has a high mortality rate when transplanted to the previous green space system, and workers cannot know the indicators of their living environment, so they cannot be targeted. sexual care.

Today's market is in urgent need of a sponge city road greening belt green space system, which can use the open space to receive and store rainwater, has good water absorption, water storage, water seepage, and water measurement functions, can facilitate the healthy growth of plants, and has good water storage capacity during droughts. It can be improved to a certain extent, and at the same time, through the good soil detection function, the soil-related indicators of the plants during the transplanting process can be understood, so that the staff can perform targeted care on the plants and greatly improve the plant survival rate.

After the vegetation layer 600 is planted, the planting soil layer 500 does not expose the soil, which plays the role of soil conservation; the tree and shrub layer 700, the plants selected are generally wind-resistant and drought-resistant plants. The planting soil layer, the vegetation layer 600 and the tree and shrub layer 700 constitute a vegetation ecosystem.

Water storage pipe 810, each unit is provided with a water storage pipe 810, the entrance of the water storage pipe 810 is set at the low-lying place on the ground surface, which is convenient for guiding rainwater; the sewage intercepting basket 820 is clamped on the water storage pipe 810, and the water storage The water flow in pipe 810 is filtered to prevent planting soil, garbage, etc. In the dirty basket 820; the valve 840, the valve 840 is located between the water storage pipe 810 and the seepage drain pipe 850, the rainwater flows into the water storage pipe 810 through the overflow plate 830, when the rainwater in the water storage pipe 810 is too much (i.e. the water storage pipe The water level of 810 has reached the position of intercepting sewage basket 820), and valve 840 can be opened automatically, and water then flows in the seepage drainage pipe 850; When seeping the drainpipe 850, water re-enters the gravel layer 300 and the planting soil layer 500 for use by plants.

Because trees will inevitably be planted when constructing a sponge city, and watering is the most important link in the later maintenance after tree planting, because if there is less water, the trees may die due to dehydration; If you water too much, it may cause water accumulation in the roots, and the tree will eventually die due to root rot. Therefore, in the post-planting maintenance of trees, how to control the degree of watering and the amount of fertilization has always been a difficult technology for the majority of greening workers. The application can improve the survival rate of transplanted plants through its unique structure combined with a soil detector.

In this solution, the soil detector 900 is used to monitor the soil, and the top of the salt probe of the soil detector 900 is an EC probe, and a strong and special metal material is used as the sensor. The EC value is used to measure the concentration of soluble salts in solution, and can also be used to measure the concentration of soluble ions in liquid fertilizers or planting media. High concentrations of soluble salts can damage plants or cause root death. The unit of EC value is expressed in mS/cm or mmhos/cm, and the measurement temperature is usually 25°C. Normal EC values range between 1-4mmhos/cm (or mS/cm). If the soluble salt content (EC value) in the matrix is too high, reverse osmosis pressure may be formed, which will replace the water in the root system and make the root tip brown or dry. The fluctuation of substrate humidity will further aggravate the problem of high soluble salt content, and the root system of the plant will be severely damaged, unable to absorb water and nutrients, resulting in symptoms such as wilting, yellowing, tissue necrosis or short plant growth. Excessively high EC value will also increase the incidence of root rot caused by the cotton rot fungus. The specific relationship between EC and plant growth is shown in Table 1 below:

Table I

Combining the above table 1 with the data detected by the soil detector 900, it is convenient for the staff to manually control the soil conditions, and control them within a relatively suitable range for the plants to be transplanted.

In this solution, the photovoltaic power generation board 950 and the lithium battery are used to supply power to the soil detector 900, which is very convenient and energy-saving.

As a preferred implementation of this solution, the salt electrode 910, the moisture electrode 920, and the pH electrode 930 are all telescopic electrodes, and the longest telescopic distance is 50 cm. The telescopic electrode can be used to monitor the deep position of the soil, and the effect is very good.

As a preferred implementation of this solution, the upper end of the planting soil layer 500 is further paved with pebble stones 510 , and the pebble stones 510 are used to divert the water flowing through the upper end of the planting soil layer 500 . Laying pebble stones 510 on the upper end of the planting soil layer 500 can play the role of diversion. The specific laying method is relatively mature in the prior art, and can be laid with reference to Baidu's experience.

As a preferred implementation of this solution, camphor 520 is also planted on the upper end of the planting soil layer 500 . In this embodiment, camphor 520 is also planted on the top of the planting soil layer 500. In the past, when planting plants were greened, the planting plants died because of improper watering. Plants such as camphor 520 were difficult to plant, but in this Under the plan, the survival rate can be higher, because camphor 520 has a higher greening effect, so this plan planted camphor 520, of course, other plants that meet the greening effect and can be adapted to this plan can also be planted.

Various modifications and changes may be made to the technical solutions and/or implementations within the protection scope of the present invention.
