Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, a precast concrete block is laid on a river bed, and the block is configured to have a rooting work, a floor protection work, a water control work, and the like, and a plant (aquatic plant) is held in the block so It is about riverbed tree planting method to plan riverbed tree planting.
[0002]
[Prior art]
River foundation works, floor protection works, water control works, etc. are constructed by laying a large number of precast concrete blocks on the river bed. It is made of concrete.
[0003]
[Problems to be solved by the invention]
When planting plants on the riverbed, it is necessary to consider the outflow of plants and soil due to water flow. However, the above-mentioned blocks such as root hardening, floor protection and water control are usually used. Since it is made of concrete, there is a problem that it is difficult to hold plants and the like.
[0004]
In view of such conventional problems, the present invention is a riverbed revegetation method for planting a precast concrete block that constitutes a gypsum work, a floor protection work, a water control work, etc., to plan greening of a riverbed with water flow. It is for the purpose of provision.
[0005]
[Means for Solving the Problems]
To solve the above-mentioned conventional problems, the features of the invention described in claim 1 for achieving the intended purpose, the upper layer in a stacked structure composed of a plain concrete lower part and the porous concrete layer part A riverbed installation block having a concave pot holding portion provided to open upward in the part, and a hole-shaped planting portion provided penetrating up and down in an arrangement surrounded by the pot holding portion , Laying on the riverbed, and constructing root fixing, floor protection and water control works with the riverbed installation block , filling the planting part with soil and planting the plant, and planting the plant in advance The porous concrete planting pot is inserted into the pot holding part, and is in the riverbed revegetation method in which the planting part and the plant in the planting pot are planted.
[0006]
In addition to the configuration of the first aspect, the feature of the invention described in claim 2 is that the riverbed installation block includes fitting projections provided in shapes and arrangements corresponding to both ends of the lower layer part. Each of the fitting recesses is fitted with each other, and is connected to a surrounding block by connecting portions provided at the four corners of the lower layer portion and laid on the river bed.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0008]
As shown in FIGS. 3 to 5, the riverbed installation block 10 is formed in a substantially rectangular parallelepiped shape, and has a two-layer structure in which the upper layer portion 10A is made of porous concrete and the lower layer portion 10B is made of solid ordinary concrete. It is designed to provide sufficient strength for construction, floor protection and water control.
[0009]
And the riverbed installation block 10 is provided with a plurality of concave pot holding portions 15, 15... Open upward in the upper layer portion 10 </ b> A, and the hole-shaped planting portions 16, 16 are provided in the pot. In an arrangement surrounded by the holding parts 15, 15..., The upper part 10 </ b> A and the lower part 10 </ b> B are vertically penetrated.
[0010]
Further, the riverbed installation block 10 is provided with fitting convex portions 12 and fitting concave portions 13 at both ends of the lower layer portion 10B in shapes and arrangements corresponding to each other, and at the four corners of the lower layer portion 10B, Connection portions 18, 18... Made of substantially U-shaped steel or the like protrude outward and are fixed.
[0011]
Moreover, as shown in FIG. 7, the planting pot 20 is formed in a shape corresponding to the pot holding part 15 of the river bed installation block 10, and is entirely made of porous concrete, and the concave planting part 26 is on the upper side. The opening is provided in the direction.
[0012]
And in the planting pot 20, the plant (aquatic plant) 30 is planted by filling the planting part 26 with soil material and putting seeds, seedlings, etc. in a place where there is no water flow or the like before construction. The roots of the plant 30 are in a state of extending through the fine voids of the porous concrete and extending to the outer surface of the planting pot 20.
[0013]
As shown in FIG. 2, first, in the construction such as the foundation work, the floor protection work, the water control work, etc., the riverbed installation blocks 10, 10. Lay them side by side so that they fit. Then, as shown in FIG. 6, the riverbed installation blocks 10, 10... Are connected to each other by passing an openable and closable annular connector 19 made of a substantially U-shaped steel material, bolts, and the like through the connecting portions 18, 18. Link.
[0014]
Then, as shown in FIG. 1, planting pots 20, 20... Rooted with plants 30, 30... Are inserted and installed in pot holders 15, 15. Further, plants 30, 30... Are planted by filling the planting portions 16, 16... Of the river bed installation blocks 10, 16.
[0015]
Then, the plants 30, 30... Of the planting pots 20, 20... Are already rooted and do not flow out due to the water flow, and further root in the fine voids of the porous concrete in the upper layer portion 10 </ b> A of the river bed installation blocks 10, 10. It grows suitably by extending.
[0016]
Moreover, since the plants 30, 30 ... of the planting parts 16, 16 ... of the riverbed blocks 10, 10 ... are weakened by the water flow by the plants 30, 30 ... of the planting pots 20, 20 ... arranged around them, The outflow of earth and sand, seedlings, etc. due to water flow is prevented, and the roots are extended to the river bed 1 so as to grow suitably.
[0017]
Therefore, the riverbed installation blocks 10, 10,... That constitute the foundation work, floor protection work, water control work, etc. can suitably hold the plants 30, 30,... Can be planned.
[0018]
【The invention's effect】
As described above, the riverbed revegetation method according to the present invention is a riverbed that constitutes a foundation work, a floor protection work, a water control work, etc. by making the lower layer part of the riverbed installation block laid on the riverbed made of ordinary concrete. The installation block can have sufficient strength. And the upper layer part of the riverbed installation block is made of porous concrete, so that the plant can be rooted and planted, and a concave pot holding part is opened upward in this upper layer part. In addition, by inserting a plant pot made of porous concrete in which plants have been planted in advance into the pot holding part, it is possible to prevent the plants from flowing out by a water flow before they take root.
[0019]
Moreover, by providing a hole-like planting part in the riverbed installation block so as to penetrate vertically, it is possible to fill the planting part with soil or the like and to plant more plants and to properly plant trees. Moreover, by arranging this planting part surrounded by a plurality of pot holding parts, the water flow is weakened by the plants in the planting pot, and the outflow of soil and plants in the planting part can be prevented.
