Description

Tetra-port for the revetment construction of the riverbank

The present invention relates to a tetrapot for the revetment construction of the riverbank, which can be easily and robustly constructed by small tetra, and can contribute to premature swelling of vegetated plants and safe growth after vegetation.

Maintenance work on rivers in and around the city is designed to mitigate the flow of rivers in order to prevent flood damage. It has been consistent with building.

However, the maintenance of river banks with raft blocks, gabions, and concrete retaining walls has advantages in terms of reliability and stability of the scour prevention function due to rainfall, ease of construction, convenient fabrication, and economic feasibility. The environmental effects such as breakage of the big world, deepening of the destruction of the live environment of the coriander site, deterioration of the natural beauty of the river, and necrosis of microorganisms that are beneficial for the purification of sewage were great.

Since such a disintegration has become more and more late, the importance of environmentally friendly revetment construction has been increasing since late.

These revetment methods rely on materials such as palm fiber, earthen bags and wooden piles, and then plant or plant vegetation seeds to reinforce the hydrophilic and greening.

Pure revetment vegetation is most suitable for the natural form of the riverbank, but it is difficult to select plant species that meet the characteristics of the river and the soil. There is still insufficient measure of the possibility of still loss of plants and lakes and increase of roughness coefficient.

The log construction method using logs is high in nature, but weak in impact, low in construction cost, and requires corrosion preservative treatment.

The lake reclamation method using the stone secures abundant space at high natural maps while providing excellent habitats for fish and living creatures, while enormous amounts of natural stones are required, which leads to difficulties in procuring stones near construction sites. The problem of the destruction of the secondary natural environment caused by the harvest is raised.

In addition, the lake reclamation method using palm bark, soft ground fiber mat, etc. has the disadvantage of being vulnerable to flooding due to low water resistance and tensile strength. There are many difficulties for large-scale revetment work.

In this respect, not only the strong revetment work, but also it helps the early growth and vigorous growth of vegetation plants after the revetment construction, and it is easy to arrange the materials for the revetment block or similar purpose. It is urgent to prepare a plan that can contribute to cost reduction.

The present invention aims to implement premature greening and perfect greening of the estuary by creating safe vegetation conditions such as easy tacking, stable throttling, and rapid flow of vegetation and safe growth after vegetation even at high flow rates.

An object of the present invention is to produce a small tetrapod developed for the protection of coastal soft zones, breakwaters, breakwaters, according to the characteristics of the river bank to facilitate the transportation and construction work, and to build a strong riverbed between the tetraport Vegetation is covered with vegetation to cover the soil, which is very effective in preventing the loss of topsoil from the river and by creating soil conditions suitable for vegetation growth, it secures sufficient dissolved oxygen to realize early greening of the river. It provides tetrafort for revetment of river banks that can be converted into environmentally friendly rivers by promoting self-cultivation of rivers, facilitating breeding of river organisms by providing abundant ecological habitats, and expanding hydrophilic spaces.

* Explanation of symbols for main parts of the drawings

1: small tetrapot 2,3: horn

4: hole 5: space

6: cover 7: plants

In Fig. 1, the relief material used in the present invention is a small tetrapot (1). The same standard horns (2), which are grounded to the ground of tetrapo, are radially extended at 120 °, and one more horn (3) of the same type is attached to the center of the point where they meet.

The small tetrapot (1) is also made of concrete when the tetrapot for coast, seawall and breakwater is made of concrete. However, rivers are more favorable than the harsh environment on the coast, so the resistance of the sewage is small, and considering the economicality, transportability, workability, and plantability in the factory or the field, it is unreasonable to apply the large tetrapots for the sea. Do.

For this reason, it is advantageous to make the tetrapot small in accordance with the conditions of the riverbank.

As shown in FIG. 2, the small tetrapot 1a has a hole 4 formed in the horns 2 and 3, which is the most important structural feature of the present invention.

This hole (4) is very convenient when threading wire rope to equipment such as fork cranes. Forming the hole (4) has the convenience of not having a separate hook for the reinforcement or steel wire, and when submerged underwater also has a side effect that provides a good habitat (river artificial fish) of river fish.

In Fig. 3, the method of arranging the small tetrapots 1 shows that the small tetrapots 1-1 of the first row are arranged side by side so that the horns 2 which are grounded form a triangle in plan view from the boundary with the lower bed. The second row of small tetrapots (1-2) are arranged such that all the ground horns (2) appear in an inverted triangle on a plane by sandwiching one ground horn (2) between the first row of small tetrapots (1-1). do. Further, the third row small tetrapots 1-3 are arranged in the same manner as the first row tetrapots 1-1 between the second row small tetrapots 1-2, and the fourth row small tetrapots 1-3 are arranged. The tetrapots (1-4) are arranged in the same manner as the second row small tetrapots (1-2) between the third row small tetrapots (1-3).

In this way, when a small tetrapot (1a) is arranged in odd rows with even rows and even rows with even rows to the raft construction point, the revetment works by itself, and between each small tetraport (1) ground horn (2) Space 5 remains. These spaces 5 are later utilized as planting spaces for planting plants suitable for the soil in the rivers below.

4 and 5, the space (5) remaining between the small tetrapot (1a) constructed on the lower surface including the subsurface water bed is soil, humus, artificial soil or cover soil (6) mixed with the lower water. Fill and chop. Finally, the cover (6), the cover (6) toward the cover (6) to plant the plant (7) suitable for the bottom, or to plant the herbaceous seeds to grow.

In the case of the small tetrapot (1a) with the hole (4) drilled by the above-mentioned method, it functions as an artificial reef and helps the breeding of fish inhabiting the bottoms. It is easy to carry around.

As described above, the revetment vegetation and greening method of the present invention is a small tetrapot that is easy to secure grounding stability, workability, and planar space. This prevents loss and erosion effect of the recovered riverbank, which is much better than other methods of revetment, and the amount of dissolved oxygen is enriched between small tetrapots. It is possible to restore natural ecosystem and maintain greening after construction.

In addition, the earthing stability is better than that of a raft block or stone, so a stronger raft effect can be expected, and the support for vegetation planted there is firm. It is rare.

Small tetrapots with holes in the horns are useful for artificial fish reefs in the water and for breeding of fishes in the bottom, and during construction, they are easy to carry by wire ropes or hooks. It is an invention.
