Description

本考案は、樹脂製網状態と不織布を用いた雨水浸透桝に関する。さらに詳しくは、樹脂製網状体と不織布の円筒状積層物からなる雨水浸透桝に関する。   The present invention relates to a rainwater permeation kit using a resin net and a nonwoven fabric. More specifically, the present invention relates to a rainwater infiltrating rod made of a cylindrical laminate of a resin net and a nonwoven fabric.

市街地では、地表面の大部分がコンクリートやアスファルトで舗装されているため、雨水の浸透域が減少し、雨水による地表面での流出量が増大してきている。その結果、大雨時において雨水管渠などの排水設備に大きな負荷がかかり、都市洪水の原因ともなっている。また、下水管渠や雨水管渠の整備が進んだ結果、雨水が地中に浸透しないので、河川に流入する地下水が減少している。その結果、河川の自然浄化能力も失われつつあり、河川の水質汚濁などの原因ともなっている。   In urban areas, most of the ground surface is paved with concrete and asphalt, so the infiltration area of rainwater has decreased, and the amount of runoff from the ground surface by rainwater has increased. As a result, a heavy load is applied to drainage facilities such as rainwater pipes during heavy rains, causing urban flooding. In addition, as a result of the advancement of sewage pipes and rainwater pipes, rainwater does not penetrate into the ground, so the amount of groundwater flowing into rivers is decreasing. As a result, the natural purification capacity of rivers is being lost, which causes water pollution of rivers.

この対策として、道路や駐車場などの舗装路に降った雨水を地中に浸透させる雨水浸透桝が開発され、道路や駐車場の側溝部分に設置されるようになった。また地域によっては、家庭の敷地内においても、屋根などに降った雨水を地中に浸透させるために雨水浸透桝を設置することが推奨されている。   As a countermeasure, rainwater infiltration dredges that penetrate rainwater that has fallen on paved roads such as roads and parking lots into the ground have been developed and have been installed in the side grooves of roads and parking lots. In some areas, it is also recommended to install rainwater infiltration basins in order to infiltrate rainwater that has fallen on the roof etc. into the ground.

従来の雨水浸透桝は施工現場で型枠を組み、その型枠内にコンクリートを打設して作製するものであり、きわめて作業に手間がかかると共に、作製者の技量によっても雨水浸透桝の出来が異なるとの課題があった。   Conventional rainwater penetrating dredgers are made by building a formwork at the construction site and placing concrete in the formwork, which is extremely labor intensive and can be done depending on the skill of the creator. There was a problem with different.

そこで、このような課題を解決するために熱可塑性樹脂で成形された雨水浸透桝が提案されている(例えば特許文献1)が、比較的大型で重量が重いため、取扱いや持運びがし難いという問題もあった。   Therefore, in order to solve such problems, a rainwater permeation mold formed of a thermoplastic resin has been proposed (for example, Patent Document 1). However, since it is relatively large and heavy, it is difficult to handle and carry. There was also a problem.

樹脂製雨水浸透桝の改良についても提案がなされている(例えば特許文献2、特許文献3)が、提案されている樹脂製雨水浸透桝は、いずれも比較的大型で重量が重いのと、予め専用の金型で成形する必要があるためコストがかかるという問題を有するものであった。
特開2000−309978号公報 特開2000−45372号公報 特開平11−256664号公報
Proposals have also been made for improvement of resin-made rainwater permeation cages (for example, Patent Documents 2 and 3). However, the proposed resin rainwater-penetration kits are all relatively large and heavy. Since it is necessary to mold with a dedicated mold, there is a problem that costs are increased.

From such a viewpoint, it is preferable to use a resin network subjected to a stretching treatment. As the resin constituting the network state, a thermoplastic resin is preferable, and a polyolefin such as polyethylene or polypropylene is particularly preferable. Preferred examples of the resin network of the present invention include a network produced by preparing a perforated sheet from a thermoplastic resin and stretching it uniaxially or biaxially. The thermoplastic resin may contain an inorganic filler such as carbon black.

このような一軸又は二軸延伸のポリオレフィン製網状体は、市場で入手することができる。市販のポリオレフィン製網状体としては、例えば三井化学産資株式会社の商品名テンサー(登録商標)を挙げることができる。   Such a uniaxial or biaxially stretched polyolefin network can be obtained on the market. As a commercially available polyolefin network, for example, trade name Tensor (registered trademark) of Mitsui Chemicals, Inc. can be mentioned.

本発明の不織布としては、ポリエチレンやポリプロピレンなどのポリオレフィンや、ポリエステルなどの熱可塑性樹脂から得られる不織布が好ましい。不織布として公知のものから適宜選択して使用することができるが、不織布としては長繊維のものが好ましいので、スパンボンド法不織布などは好ましく使用することができる。中でも、ポリプロピレンのスパンボンド法不織布が好ましい。   The nonwoven fabric of the present invention is preferably a nonwoven fabric obtained from a polyolefin such as polyethylene or polypropylene, or a thermoplastic resin such as polyester. The nonwoven fabric can be appropriately selected from known ones and used, but the nonwoven fabric is preferably a long fiber, so that a spunbond nonwoven fabric can be preferably used. Among these, a polypropylene spunbond nonwoven fabric is preferable.

不織布は、エンボスやヒートボンドなどの工程を経たものを使用することができるが、本考案では、目付が40〜800g/cm程度のものが好ましい。 As the non-woven fabric, those having undergone processes such as embossing and heat bonding can be used. In the present invention, those having a basis weight of about 40 to 800 g / cm 2 are preferable.

本考案で用いる不織布は、非イオン系界面活性剤、アニオン系界面活性剤などの親水化剤で親水処理されたものであってもよい。   The nonwoven fabric used in the present invention may be subjected to a hydrophilic treatment with a hydrophilizing agent such as a nonionic surfactant or an anionic surfactant.

本考案の雨水浸透桝は、樹脂製網状体の円筒状物であって、その内側に不織布が積層されてもので構成されているが、このような円筒状積層物を形成させる方法の一例を図面に基づいて説明する。   The rainwater infiltration trough of the present invention is a cylindrical product made of a resin net, and is composed of a non-woven fabric laminated on the inside thereof. An example of a method for forming such a cylindrical laminate is shown below. This will be described with reference to the drawings.

図1は、長方形の樹脂製網状体1に不織布2が積層されている状態を示す概略図である。不織布2は、適当な箇所で適当な手段で樹脂製網状体1と結合されていることが好ましい。図1においては、長辺付近で複数箇所で、不織布2がCリンガー3を用いて樹脂製網状体1に結合されている。樹脂製網状体1は、形成する雨水浸透桝の形状によって、正方形をしていても差し支えない。   FIG. 1 is a schematic view showing a state in which a nonwoven fabric 2 is laminated on a rectangular resin network 1. The nonwoven fabric 2 is preferably bonded to the resin network 1 at an appropriate location by an appropriate means. In FIG. 1, the nonwoven fabric 2 is bonded to the resin net 1 using a C ringer 3 at a plurality of locations near the long side. The resin net-like body 1 may have a square shape depending on the shape of the rainwater infiltration trough to be formed.

図1の長方形の樹脂製網状体積層物は、不織布を内側にして円筒状に曲げられて、網状体両端を結合させることによって円筒物が形成される。図2は、樹脂製網状体の両端を結合させる方法の一例を示す部分概略図である。網状体の一端は、他端の網目を通して反対側に曲げられて、曲げられた部分4と他端5の間にジョイナー6が差し込まれることによって樹脂製網状体の両端が結合されている。かくして図3に示すようは円筒状物が形成される。円筒状物7の内側は不織布によって積層されている。   The rectangular resin net laminate of FIG. 1 is bent into a cylindrical shape with the nonwoven fabric inside, and a cylindrical object is formed by joining both ends of the net. FIG. 2 is a partial schematic view showing an example of a method for joining both ends of a resin net. One end of the mesh body is bent to the opposite side through the mesh at the other end, and a joiner 6 is inserted between the bent portion 4 and the other end 5 so that both ends of the resin mesh body are coupled. Thus, a cylindrical object is formed as shown in FIG. The inside of the cylindrical object 7 is laminated with a nonwoven fabric.

得られる樹脂製網状体円筒状積層物は、軽量であるが、雨水浸透桝として使用されるとき、雨水浸透桝の周辺には不織布の透水性によって適度の水が流れ出すと同時に、周辺の土砂は不織布層に遮られて雨水浸透桝に流入することはないので、雨水浸透桝としての優れた機能を果たし、その機能を長時間持続させることができる。   The resulting resin net-like cylindrical laminate is lightweight, but when used as a rainwater permeation dredge, moderate water flows out around the rainwater permeation dredge due to the water permeability of the nonwoven fabric, and the surrounding earth and sand are Since it is not blocked by the non-woven fabric layer and flows into the rainwater permeation trough, it functions as a rainwater permeation trough and can maintain its function for a long time.

円筒状物7は上方及び下方に開放されているが、上方または下方の開放部を不織布製のキャップで覆ってもよい。図4は、キャップの一例を示す概略図である。図4のキャップ8は、円筒状物の開放部を覆う不織布円形部8−1の縁部において垂直方向に円筒状垂直部8−2が形成された形状をしており、これによって樹脂製網状体の円筒状積層物の上方開放部を上からしたに、また下方開放部を下から上に覆うことができる。   The cylindrical object 7 is opened upward and downward, but the upper or lower opening may be covered with a non-woven cap. FIG. 4 is a schematic diagram illustrating an example of a cap. The cap 8 of FIG. 4 has a shape in which a cylindrical vertical portion 8-2 is formed in the vertical direction at the edge of the nonwoven fabric circular portion 8-1 that covers the open portion of the cylindrical object. The upper open portion of the cylindrical laminate of the body can be covered from the top, and the lower open portion can be covered from the bottom up.

図3の円筒状積層物7には、下方開放部がキャップ8によって覆われている。
図5は、下方開放部がキャップ8によって覆われている円筒状積層物を示す正面図である。
In the cylindrical laminate 7 of FIG. 3, the lower open portion is covered with a cap 8.
FIG. 5 is a front view showing a cylindrical laminate in which the lower open portion is covered by the cap 8.

本考案の樹脂製網状体円筒状積層物を、図3のキャップ8で覆うことは必須ではない。図6に示すように、円筒状積層物7の開放部が不織布シート9で覆われて、円筒物からはみ出した不織布をたたみ込むことによって開放部が不織布シートで覆われている態様も本考案の好ましい態様である。   It is not essential to cover the resin net-like cylindrical laminate of the present invention with the cap 8 of FIG. As shown in FIG. 6, the open part of the cylindrical laminate 7 is covered with a non-woven fabric sheet 9, and the open part is covered with the non-woven sheet by folding the non-woven fabric protruding from the cylindrical object. This is a preferred embodiment.

樹脂製網状体円筒状積層物の開放部を不織布によって覆うことによって上方および下方からのごみの流入や土砂の流入を防ぎ水だけを通過させることができるので、雨水浸透桝としての機能を持続させることができる。   By covering the open part of the resin net-like cylindrical laminate with non-woven fabric, it is possible to prevent the inflow of dust from the upper and lower sides and the inflow of earth and sand, allowing only water to pass through. be able to.

樹脂製網状体円筒状積層物の開放部を不織布によって覆うのは、上方及び下方のいずれか一方でもいいし、その双方を覆うこともできる。上方及び下方の開放部を不織布によって覆う態様はより好ましい態様である。   The open part of the resin net-like cylindrical laminate may be covered with the nonwoven fabric either on the upper side or on the lower side, or both of them. A mode in which the upper and lower open portions are covered with the nonwoven fabric is a more preferable mode.

本考案の樹脂製網状体円筒状積層物を雨水浸透桝をして使用するに際して、その内部を砂利等で充填することができる。砂利等で充填することによって、上部地盤の重量を支持するとともに、集めた雨水を砂利の間隙から徐々に排水するという効果が得られる。   When the resin-made net-like cylindrical laminate of the present invention is used with rainwater permeation troughs, the inside thereof can be filled with gravel or the like. By filling with gravel or the like, the effect of supporting the weight of the upper ground and gradually draining the collected rainwater from the gaps in the gravel can be obtained.

図7は、本考案の樹脂製網状体円筒状積層物7が、その下方開放部を不織布キャップ8で覆われ、内部が砂利10で充填されている様子を示す概略図である。このような樹脂製網状体円筒状積層物7の上方開放部をさらに不織布キャップ8で覆って、雨水浸透桝として敷設した様子が、図8の概略図に示されている。路面の雨水は、側溝11を通って雨水浸透桝Aの上方の集水孔12とキャップ8を通過して流れ込み、雨水浸透桝Aに貯留された雨水は、下方キャップ8を通過して、地面に浸透している。   FIG. 7 is a schematic view showing that the resin net-like cylindrical laminate 7 of the present invention is covered with a non-woven cap 8 at the lower open portion and filled with gravel 10 inside. A schematic view of FIG. 8 shows a state in which the upper open portion of such a resin net-like cylindrical laminate 7 is further covered with a nonwoven fabric cap 8 and laid as a rainwater permeation trough. The rainwater on the road flows through the side groove 11 and flows through the water collecting hole 12 and the cap 8 above the rainwater infiltration basin A, and the rainwater stored in the rainwater infiltration basin A passes through the lower cap 8 and passes through the ground. Has penetrated.
