Abstract

<P>PROBLEM TO BE SOLVED: To easily landscape a river revetment using natural stones and plants without providing scaffolding. <P>SOLUTION: A greening base 1 consisting of a planter 4 and a board 12 with natural stones 11 affixed thereto is secured to the top end 21 of an existing concrete revetment 2 with anchors 3. The board 12 with the natural stones 11 affixed thereto and the planter 4 are separately fabricated and assembled on site. The board 12 extends downward from the bottom of the planter, and the revetment is landscaped with the natural stones 11. When the natural stones 11 are porous the base's surface is kept moist to allow moss to grow and small animals to inhabit. The planter 4 has a slanted bottom face to guide rain that entered the planter 4 onto the surface of the board 12 and keep the natural stones 11 wet enough for plants including moss to grow easily. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
都市河川に多く見られる三面張りコンクリート護岸や鋼矢板護岸の表面に生物の棲息環境を提供すると共に、河川の水流に影響を与えないようにした護岸緑化方法及びその方法に使用する緑化基材に関する。
【0002】
【従来の技術】
近年、無機質なコンクリート構造物の表面を緑化して修景することが求められており、種々の提案がされている。例えば、多孔質天然石を貼り付けた中空の生態系育成用ボードをコンクリート構造物の表面に接着剤で貼り付けるものである。
【0003】
【発明が解決するための課題】
しかし、都市河川の護岸は垂直に近いコンクリート構造物なので、エポキシ樹脂系の樹脂モルタルやセメントモルタルの接着剤で貼り付けるには足場が必要である。また、接着剤が硬化するまでに時間がかかり、ボードを仮止めする手段が必要なので施工が面倒であった。更に、現場で接着剤を使用するため、接着剤の溶剤成分を環境に撒き散らすことにもなり、環境ホルモンの問題を引き起こす可能性がある。
【0004】
低水位まで自然石を貼り付けた場合、自然石によって護岸表面に凹凸が形成されて粗度が高くなり、水流に対する抵抗が大きくなって増水時に水流が乱されて洪水を引き起こす可能性があり問題があった。
本発明は、足場等の仮設設備を必要とせずに、また、水流に影響を与えないようにして河川の護岸を自然石で修景できるようにするものである。
【0005】
【課題を解決するための手段】
プランターの一側面に自然石を貼り付けたボードを固定した緑化基材のプランターを護岸天端に固定し、プランターの底部より下側に延びるようにすることによってプランターに植えた植物が護岸側に垂れ下がるようにするとともに、自然石で護岸を修景するようにしたものである。
【0006】
【実施例】
実施例1
図1に示す緑化基材1は、護岸天端に固定する部分が箱状のプランター4であり、プランター4の底部を護岸天端にアンカー3等で固定するか、または、単に護岸天端に設置する。プランター4の側面には自然石11を貼り付けたボード12が固定してある。ボード12は軽量で強度を有するものが好ましく、中空の軽量パネル等を使用し、熔岩を表面に接着剤で固定したものである。
ボード12は、プランター4の側板にネジ等で固定してあり、着脱自在である。プランター4とボード12を一体に成形することも可能であるが、形状が空間を多く占有して運搬に対して不適切であるので、ボード12とプランター4を別体として製造し、現場で組み立てるほうが輸送費の面から効率的である。
【0007】
ボード12に貫通穴(図示しない)を形成し、裏面にヤシの繊維を絡み合わせたものを接着剤で固着するなどして保水層とし、表面に貼り付けた自然石に水分を供給し、苔などが生育しやすいようにする。また、ボード12を中空体とし、高吸水性樹脂(例えばデンプン−アクリロニトリルグラフト重合体の加水分解物、セルロース−アクリロニトリルグラフト重合体の加水分解物など)、粘土(モンモリナイト、アロフェインを含有しているもの)、バーミキュライト、真珠岩系のパーライト、焼成珪藻土などの保水物質を充填したものを中空部に充填して保水層とする。
【0008】
実施例2
図2に示すものは、護岸天端に設置するプランター4の底部を傾斜面41とし、プランター4の側面の下側に複数の孔42、または、スリットを設けたものである。この側面の孔42等の開口部にはプランター内の土が流出しないようにネットまたはフィルターが設置してある。従って、雨がプランター4内に落ち込み、傾斜面41を流下して孔42から外側に流れ出し、ボード12に水を供給して湿潤状態を維持する。ボード12の表面の自然石11も湿潤状態が保たれ、苔等の植物が生育し易くなる。
【0009】
【発明の効果】
本発明は、プランターを有する緑化基材を河川の護岸の天端に固定することによって護岸を修景するものであり、河川に重機を入れたり、足場を設置することなく施工ができ、また、河川の流れをとめることがないので施工が簡単である。プランターに植えた植物が繁茂して護岸を緑化するとともに、ボードの表面に多孔質の自然石を貼り付けると、苔などが繁茂しやすくなる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a revetment revegetation method that provides a habitat for living organisms on the surface of a three-faced concrete revetment or a steel sheet pile revetment commonly found in urban rivers and does not affect the water flow of the river, and a revegetation base material used in the method. .
[0002]
[Prior art]
In recent years, there has been a demand for greening the surface of an inorganic concrete structure to improve the scenery, and various proposals have been made. For example, a hollow ecosystem breeding board to which a porous natural stone is stuck is stuck to the surface of a concrete structure with an adhesive.
[0003]
[Problems to be solved by the invention]
However, the seawalls of urban rivers are concrete structures that are nearly vertical, so scaffolding is required to attach them with epoxy resin mortar or cement mortar adhesive. In addition, it takes time until the adhesive is hardened, and a means for temporarily fixing the board is required, so that the installation is troublesome. Further, since the adhesive is used on site, the solvent component of the adhesive is scattered to the environment, which may cause environmental hormone problems.
[0004]
If natural stone is stuck to a low water level, natural stones will create irregularities on the revetment surface, increasing roughness, increasing resistance to water flow, disturbing the water flow when the water rises, and causing flooding. was there.
The present invention enables the revetment of rivers to be landscaped with natural stones without the need for temporary facilities such as scaffolds and without affecting the water flow.
[0005]
[Means for Solving the Problems]
Planting the planting planter on the revetment side by fixing the planter of the greening base material that fixed the board with natural stone stuck on one side of the planter to the top of the revetment and extending below the bottom of the planter In addition to hanging down, the revetment was renovated with natural stones.
[0006]
【Example】
Example 1
The greening base material 1 shown in FIG. 1 is a box-shaped planter 4 in which a portion to be fixed to the seawall top is fixed to the bottom of the planter 4 with the anchor 3 or the like, or simply to the seawall top. Install. A board 12 on which a natural stone 11 is stuck is fixed to a side surface of the planter 4. The board 12 is preferably lightweight and strong, and is formed by using a hollow lightweight panel or the like and fixing the lava to the surface with an adhesive.
The board 12 is fixed to a side plate of the planter 4 with screws or the like, and is detachable. Although it is possible to form the planter 4 and the board 12 integrally, since the shape occupies a lot of space and is unsuitable for transportation, the board 12 and the planter 4 are manufactured separately and assembled on site. It is more efficient in terms of transportation costs.
[0007]
A through-hole (not shown) is formed in the board 12, and a tangled coconut fiber is bonded to the back surface with an adhesive to form a water retention layer. The moss is supplied with water to the natural stone attached to the surface. Make it easy to grow. Further, the board 12 is formed as a hollow body, and contains a highly water-absorbing resin (eg, a hydrolyzate of a starch-acrylonitrile graft polymer, a hydrolyzate of a cellulose-acrylonitrile graft polymer, etc.), and a clay (containing montmorillonite, allophane). ), A hollow body filled with a water-retaining substance such as vermiculite, perlite of perlite, calcined diatomaceous earth, etc., to form a water-retaining layer.
[0008]
Example 2
In FIG. 2, the bottom of the planter 4 installed at the top of the seawall is an inclined surface 41, and a plurality of holes 42 or slits are provided below the side surface of the planter 4. A net or a filter is provided in an opening such as the hole 42 on the side surface so that soil in the planter does not flow out. Therefore, rain falls into the planter 4, flows down the inclined surface 41, flows outward from the hole 42, and supplies water to the board 12 to maintain a wet state. The natural stone 11 on the surface of the board 12 is also kept in a wet state, and plants such as moss grow easily.
[0009]
【The invention's effect】
The present invention is intended to scenic the revetment by fixing the greening base material having a planter to the top of the revetment of the river, and can be constructed without installing heavy equipment in the river or installing a scaffold, Construction is easy because the flow of the river is not stopped. Plants planted in planters thrive and green the seawall, and when natural porous stones are pasted on the surface of the board, moss and the like can easily thrive.
