Description

Planting belts construction method for street trees}

The present invention relates to a construction method of the roadside drinking water fountain to make the rainwater falling on the pavement and pavement to be useful for improving roadside water and groundwater level and microclimate control.

Due to industrialization and urbanization, green space in cities is rapidly decreasing. In addition, due to the heating of urban homes and buildings, the exhaust of automobiles, and the smoke of factory operations, the seriousness of environmental problems such as air pollution and soil pollution is also increasing day by day. In addition, the growing environment of impervious pavement in urban areas is increasing, and the growing environment of roadside trees is not only worsening, but also the unavoidable damage and flooding caused by the backflow to the sewers by promoting the concentration and rapid flow of rainwater to specific points. In addition, it has been the main culprit to deteriorate the urban environment by disrupting or distorting the water cycle of the city, resulting in the circulation imbalance of urban materials such as desertification of the city, destruction of biological habitats, and dryness of urban rivers.

The city's street trees absorb air pollutants in the harsh urban environment, reduce oxygen sources such as oxygen supply, soundproofing, windproof and snowproofing, and absorb solar radiation to control air temperature and humidity, and snow rain dew. It is one of the important factors in the qualitative improvement of the urban environment, which has aesthetic functions such as suppressing the damage caused by the air, controlling the climate of the city such as controlling the air volume, providing green greenery, and improving the emotion of the citizens.

Urban roadside trees also play an important role as a means of restoring the natural functionality of the city, as they serve as an excellent resting place for the wild birds that live in the city, as well as the connecting axis of the green areas.

However, the growth conditions of roadside trees are very poor due to the increase of impermeable pavement area, pressure damage, drying damage due to the drop of groundwater level in the city, and various environmental pollutants and environmental pressure.

In this regard, in order to improve the quality of the street environment as well as the growth environment of roadside trees, it is urgent to reorganize the excellent management system to restore the material circulation system in the city and to prepare green land development measures in order to improve the growth of roadside trees. Also desperate.

Accordingly, an object of the present invention is to provide a roadside drinking water fountain useful for improving roadside water and groundwater level and microclimate control of rainwater falling on pavement and pavement.

The purpose of the above is to change the existing point-of-the-line street drinking water fountain to a linear drinking water, which greatly expands the drinking water area, to form a concave groove lower than the pavement road or pavement, and induces the rainwater around the drinking water pool to gather into the drinking water. This can be achieved by providing sufficient time margin for penetration.

In addition, the present invention is to control the planting depth of the roadside tree so that rainwater is not concentrated to a specific place, and to reduce the impermeable packaging area as possible to facilitate the smooth inflow of rainwater into the drinking water and to penetrate into the ground more effectively achieve the above object. It was made possible.

In the present invention, the main building material for roadside drinking water is crushed stone and sand, topsoil, and drain pipe having a particle size of φ10 to 30. Crushed stone is effective to allow rainwater to penetrate smoothly into the ground. It is placed on the bottom of the trench. The sand is laid on the crushed stone so that rainwater can penetrate smoothly into the ground. The topsoil is collected from soil excavated at the site of the site where the drinking water will be planted and used for planting trees. In addition, the drain pipe is to protect the drinking fountain by quickly draining the rainwater overflowing from the drinking fountain from the drinking fountain to the drain, it should be easy and low cost in case of emergency, synthetic resin pipe is suitable in terms of workability and procurement.

The roadside drinking water using the construction material proceeds in the order of trenching, roadside fixing, crushed stone laying, sand laying, topsoil laying, drainage pipe installation, soil backfilling, planting of shrubs or herbaceous plants, finishing. This process is described in more detail as follows.

First, the trench 1 is performed to a depth of 1 m along the road boundary line to plant the roadside trees. If the planting depth (root height) of the roadside tree to be planted is required more than 1m, consider only this and dug deeper only the parts necessary for the roadside planting. The topsoil produced by the dig is collected in a regular place and recycled when the soil is backfilled.

The roadside tree 2 is arrange | positioned at every predetermined place, and it fills up with loam and fixes the roadside tree 2. The planting depth of the roadside tree 2 matches the uppermost part of the root powder with the reference plane of the road to prevent the rainwater flowing into the roadside drinking water to be concentrated at a specific point.

After fixing the roadside tree 2, the crushed stone 3 is evenly laid in the space between the roadside trees 2 with THK300 thickness, and the sand 4 is evenly laid with THK100 thickness on the crushed stone 3 layer. Subsequently, the topsoil (5) collected in one place at the time of excavation is evenly laid on the sand (4) layer with a thickness of THK100.

In case of instantaneous rain or heavy rainfall, the drain pipe (7) is installed at the upper end of the lowest area in the drinking fountain (a) so that it can be drained quickly to the drainage channel (6) such as a road side. . It is sufficient that the pipe diameter of the drain pipe 7 is about 50 mm.

Using the soil collected when digging (1) backfilled into the concave groove shape (8) and performs a flat work. At this time, the inclination of drinking fountain is about 1: 5. The inclination of the drinking fountain is lowered along the direction of the arrow in FIG. 3 from the center between the trees 2 and at the same time, and lowered from the side of the drinking table to the center of the width thereof.

Planting shrubs or herbaceous plants (9) according to field conditions in the space between the roadside trees (2) and the roadside trees, and finish the work, such as compacting the installation of watering holding trees.

The roadside drinking water according to the present invention is particularly suitable for roadsides in various complexes, such as roadsides with low traffic volume, low-speed roads, environmentally friendly new cities and residential areas, apartment complexes, industrial complexes, research complexes, and recreational complexes.

As described above, the roadside drinking water fountain construction method of the present invention collects rainwater falling on the ground surface, induces a smooth penetration into the ground, and improves the physical environment of the soil around the roadside, thereby contributing to the improvement of the roadside growth environment, It can improve the urban environment by preventing the fall of groundwater level.

In addition, it is possible to provide a growing condition that can be used as a roadside tree species that could not be used because of poor environmental conditions can create a unique landscape scenery for each region.

In addition, the present invention helps prevent flooding due to intensive rainfall by inhibiting stormwater inflow and delaying the time from the start of the rainfall to the outflow.
