Description
本発明は、海岸沿いにそそり立つコンクリート等で形成された防潮堤面に対する緑化に関するものである。 The present invention relates to greening of a tide wall surface made of concrete or the like standing along a coast.
高潮や津波による災害防除を図るために、海岸沿いには傾斜堤、緩傾斜堤、直立堤、混成堤のいずれかによる防潮堤が構築されているが周囲の環境と調和せず、地域景観上好ましいものとは言えない、特に垂直状に形成されている直立堤型の防潮堤は、直射日光を反射させ周囲の気温を上昇させるとともに市街地においては、ヒートアンランド現象の一因ともなっている。 In order to prevent disasters caused by storm surges and tsunamis, coastal levees are constructed along the coast, including sloping dams, gentle sloping dams, upright dykes, and mixed dykes, which are not in harmony with the surrounding environment and An upright levee type dyke, which is not preferred, and is formed in a vertical shape, reflects direct sunlight and raises the ambient temperature, and also contributes to the heat unland phenomenon in urban areas.
そこで、これを解消するために直立防潮堤の下部地面に蔦苗を植付け、外壁面に若干の間隔を置いて張設したネットに蔦を這わせ、外壁面を緑化するといった方法が取られているが直立防潮堤下部の地面から植付けた蔦が外壁面を緑化するには、複数年の年月がかかるとともに部分的にしか緑化が進まないという問題点があった。 Therefore, in order to solve this problem, a method was adopted in which seedlings were planted on the lower ground of the upright seawall, and the outer wall surface was greened by placing the cocoons on the net stretched at some intervals on the outer wall surface. However, it took several years for the coral planted from the ground under the upright seawall to greenen the outer wall, and there was a problem that the greening only progressed partially.
そこで、上記の問題点を解消する方法として擁壁面に培養土収容用の植栽ポケットを設けるとともに、前記擁壁面に植栽固定部材を固着し、前記植栽ポケットに樹木を植栽し、当該樹木の大枝を擁壁面に沿わせ、平面的に広げた状態に曲げて、前記固定部材に固定して擁壁面を緑化する特許文献１やコンクリート等の防潮堤面に、山砂と保水剤と腐葉土とセメント系接着剤とからなる下層基盤を重ね、前記下層基盤表面に保水剤と腐葉土とセメント系接着剤とからなる上層基盤を重ね、前記上層基盤に植物を植栽または播種して外壁面の緑化を図る特許文献２の工法等が開示されている。 Therefore, as a method of solving the above problems, a planting pocket for accommodating culture soil is provided on the retaining wall, and a planting fixing member is fixed to the retaining wall, and a tree is planted in the planting pocket, A large branch of a tree is bent along a retaining wall, bent in a flattened state, fixed to the fixing member, and greened on the retaining wall. Overlay the lower layer base made of humus and cement adhesive, overlay the upper layer base made of water retention agent, humus and cement adhesive on the surface of the lower base, and plant or seed the plant on the upper layer base Japanese Patent Application Laid-Open No. H10-228707 discloses a method for greening.
しかし、特許文献１の工法には、植栽された樹木の幹や枝の部分を壁面に沿わせ、広げた状態で固定部材に針金等の結束材で結束固定されるため、植栽木の生長に伴い結束部分が首絞め状態となり風雪時の風圧や雪の重みで結束部分から折れやすい問題点や植栽木が枯れた場合に植え替えに手間が係る問題点がある。 However, in the construction method of Patent Document 1, the planted tree grows because the trunk and branches of the planted tree are stretched along the wall surface and are bound and fixed to the fixing member with a binding material such as a wire. As a result, the bundling portion is squeezed into the neck, and there are problems that the wind pressure during snow and snow and the weight of the snow tend to break the bundling portion, and when the planted tree withers, the replanting takes time.
また、特許文献２の工法は、外壁面へ網を張らず大型機械を用いて直接壁面に１０センチ厚の基盤材を吹付、さらにその上に３〜５センチ厚の基盤材を吹付、外壁面に植生基盤土層を形成して緑化を図る方法なので、施工費が嵩むほかに外壁面の勾配が急な所では、植生基盤土が流失・滑落してしまう恐れが高く、急勾配な外壁面での施工には問題点がある。 Moreover, the construction method of patent document 2 sprays a 10-cm-thick base material directly on a wall surface using a large machine without stretching a net on the outer wall surface, and further sprays a 3-5-cm-thick base material on the outer wall surface. This is a method of greening by forming a vegetation base soil layer on the ground, and in addition to the construction cost, there is a high risk that the vegetation base soil will be washed away or slipped down when the slope of the outer wall is steep. There is a problem with the construction in Japan.
急勾配なコンクリート等の防潮堤面でも宿根草や低木等の植栽が可能な緑化装置で早期緑化と長期的緑化が図られ、地域環境の景観向上が図られる防潮堤面の緑化システムの提供。 Providing a greening system for the tide bank surface that enables early and long-term greening with a planting device that can plant perennial grass and shrubs even on steep concrete tide wall surfaces such as concrete.

The grooved strut and the planting mat A 2 cm thick planting mat body is tightly fixed on the body, and a planting base soil layer is formed on the wall surface by two layers of the planting mat body. A rainwater receiving section, a water storage room, A planting container provided with a communication groove in which the planting mat body and the soil in the planting container are in close contact with each other is fixed to the vegetation base soil layer through the grooved support, A levee surface planting system where rainwater receivers are installed and water is supplied to the vegetation basement soil layer on the wall.
なお、植栽マット体の植生基盤土層越しから溝付支柱に固着される植栽容器は、表面の傾斜状板が多くの雨水を取り入れ可能に植栽容器の上部から数センチ長くはみ出る長さで雨水受部が形成され、底部には貯水室、後面部には植栽マット体に余剰水を給水するとともに植物根が植栽容器から植栽基盤土層に伸長可能とする複数の連通溝が形成されている植栽容器が固定され、それにより植栽容器内の用土と防潮堤面の植栽マット体の植栽基盤土が一体化され緑化が図られる。また、前記植栽容器は腐蝕しにくい樹脂製やアクリル製板で形成され、階段状に設置される植栽容器に植栽される植栽植物が上部の植栽容器につかえることがないように直角三角形状に形成されている。 In addition, the planting container that is fixed to the grooved strut from the vegetation base soil layer of the planting mat body is a length that protrudes several centimeters longer from the top of the planting container so that the inclined board on the surface can take in much rainwater A drainage receiving part is formed at the bottom, a water storage chamber at the bottom, a surplus water supply to the planting mat body at the rear, and a plurality of communicating grooves that allow the plant roots to extend from the planting container to the planting soil layer The planting container in which is formed is fixed, whereby the soil in the planting container and the planting base soil of the planting mat body on the seawall are integrated and greening is achieved. In addition, the planting container is made of a resin or acrylic plate that is not easily corroded, so that the planting plant planted in the planting container installed in a staircase shape cannot be used in the upper planting container It is formed in a right triangle shape.
植栽基盤土層を植栽マット体で形成することにより、豪雨や霜柱等で基盤土が流失することもなく、長期に渡り基盤土の保持を可能とし、植栽容器に植栽された苗木等は、植栽容器に形成された雨水受部や貯水室からの吸水により生育に必要な水分が確保され、やがて生育に伴い植栽室から植生基盤土層に植物根が伸張することにより、新たな水分確保と強風等による飛散や倒木といったことも防止され、植栽植物が長期に渡り生育可能となる防潮堤面の緑化が図られる壁面緑化システムである。 By forming the planting foundation soil layer with a planting mat body, the foundation soil can be retained for a long time without heavy soil and frost pillars being washed away, and seedlings planted in planting containers The water necessary for growth is secured by water absorption from the rainwater receiving part and water storage chamber formed in the planting container, etc., and the plant roots extend from the planting room to the vegetation base soil layer with the growth, It is a wall greening system that can prevent water splashes and fallen trees due to strong winds, etc., and enables the planting plants to grow over a long period of time, thereby greening the seawall.

In addition, let the communicating groove formed in a back surface board be 1-3 cm width | variety which a plant root can extend | expand.
図６は、図４の植栽容器の内部を示すものである。植栽容器の内部は、シーリング材にて継ぎ目がコーティングされ、底から３〜５センチの高さで貯水室が形成される。この貯水室には、水の保持が可能な軽石１６を敷き並べ、軽石の上部を覆うように水を通し基盤土を通さないポリエステル製不織布の吸水シート１７を敷設し、この上に植生基盤土が積層される植栽容器１１である。 FIG. 6 shows the inside of the planting container of FIG. The inside of the planting container is coated with a seam with a sealing material, and a water storage chamber is formed at a height of 3 to 5 cm from the bottom. In this water storage room, pumice 16 capable of holding water is laid, and a non-woven water absorbent sheet 17 made of polyester that does not allow basement soil to pass through the top of the pumice is laid. Is a planting container 11 to be stacked.
図７は、図２〜図３で防潮堤面に形成された植生基盤土層の植栽マット体に図４〜図６で形成された植栽容器を任意間隔で密着させ、２センチ厚の植栽マット体９越しに植栽容器１１を溝付支柱部１に固定し、防潮堤面３に植栽基盤土層の植栽マット体と植栽容器を固定する。また、植栽容器が形成された防潮堤の天場部分に雨水を集水する雨水受容器１８が設置され、集水した雨水が植栽基盤土層の植栽マット体に給水される構成で設置される防潮堤面の緑化システムを示したものである。なお、雨水受容器内の底部は、雨水が植栽基盤土層側に流れるように傾斜状に形成され、流水口１９から雨水が植栽基盤土層に流水するがゴミ等で流水口が詰まことのないように吸出し防止マット２０が全面に敷詰められている雨水受容器１８である。 FIG. 7 shows that the planting container formed in FIGS. 4 to 6 is in close contact with the planting mat body of the vegetation basement soil layer formed on the seawall surface in FIGS. The planting container 11 is fixed to the grooved column part 1 through the planting mat body 9, and the planting mat body and the planting container of the planting base soil layer are fixed to the seawall 3. In addition, a rainwater receiver 18 that collects rainwater is installed at the heaven part of the seawall where the planting container is formed, and the collected rainwater is supplied to the planting mat body of the planting foundation soil layer. This shows the greening system of the installed seawall. In addition, the bottom of the rainwater receiver is formed in an inclined shape so that rainwater flows toward the planting soil layer, and rainwater flows from the drainage port 19 to the planting soil layer, but the drainage port is clogged with dust. This is a rainwater receiver 18 in which a suck-out prevention mat 20 is laid on the entire surface so as not to occur.
図８は、防潮堤面の緑化システムを防潮堤面へ設置し、植栽緑化した状態を示す実地例である。防潮堤面へ設置された防潮堤面の緑化システムは、図１〜図７の手順で形成され、植栽容器１１内に植生基盤土２１とともに宿根草や蔦植物２２等を植栽して防潮堤面の緑化を図る。植栽容器を植栽マット体に密着固定することにより植栽容器の後面部は植栽基盤土層に密着一体化し、植栽された植物が生育するとともに植物根が植栽容器から植栽基盤土層に伸長し、強風や振動で植栽物が倒伏することもなく長期緑化が望める。 FIG. 8 is a practical example showing a state where the greening system of the seawall is installed on the seawall and planted. The tide bank surface greening system installed on the tide bank surface is formed according to the procedure shown in FIGS. 1 to 7, and the tide bank is constructed by planting perennial grass, birch plant 22 and the like together with vegetation base soil 21 in the planting container 11. Plan greening of the surface. By sticking and fixing the planting container to the planting mat body, the rear part of the planting container is closely integrated with the planting base soil layer, and the planted plant grows and the plant root grows from the planting base. It grows in the soil layer and long-term greening can be expected without planting the plant by strong winds and vibrations.
上記の防潮堤面への緑化は、植栽基盤土層を植栽マット体で形成することにより風雨等で植栽基盤土が流失することがなく、当該植栽基盤土層面に設置される植栽容器は、雨水を取り入れる雨水受部と貯水槽が形成されており、後面板の連通溝からは植栽基盤土層に給水と植物根の伸長が可能に形成されており、植栽容器に植栽された植物は、急勾配なコンクリート等の防潮堤面でも早期緑化と長期的緑化が可能な防潮堤面の緑化方法である。 The above greening on the seawall can be done by forming the planting soil layer with a planting mat body so that the planting soil will not be washed away by wind and rain, etc. The planting vessel has a rainwater receiving part and a water storage tank for taking in rainwater, and the communication groove on the rear plate is formed so that water supply and plant roots can be extended to the planting base soil layer. The planted plant is a method of greening the tide wall that enables early and long-term greening even on a tide wall such as steep concrete.
本防潮堤面の緑化システムを用いた防潮堤面の緑化は、防潮堤に限らず各壁面の早期緑化を実現するとともに長期的緑化も可能とする緑化システムであり、周囲の自然環境調和と景観の保全を図り、ヒートアイランド現象の発生を防止できる自然環境の復元方法として今後利用される可能性の高い防潮堤面の緑化システムである。 The revetment surface revegetation using this revetment surface revegetation system is a revegetation system that enables early revegetation of each wall as well as the revetment and enables long-term revegetation. It is a greening system for seawalls that is likely to be used in the future as a natural environment restoration method that can prevent the occurrence of heat island phenomenon.
