Description

この発明は、道路に設置される鋼製排水溝に関し、さらに言えば、集水と排水の機能を分離させた(別々に備えた)鋼管から成るコンパクトサイズの排水溝の技術分野に属する。   The present invention relates to a steel drainage ditch installed on a road, and more particularly, to a technical field of a compact drainage ditch made of a steel pipe having (separately provided) water collecting and draining functions.

従来、路面排水溝(排水路)として、コンクリート製のものが知られている。しかし、コンクリート製品の場合、重量が重いほかコンクリート厚が厚く、必要な内空断面を確保するには製品サイズが大きくなるため掘削量が多くなる等、不経済、不合理という問題があった。
特にこの問題は、山岳トンネルやボックスカルバートの中空断面のサイズは排水側溝の高さに応じて増大する等、顕著化し、近年、掘削量低減等の経済性を考慮し、従来と同程度の排水量を維持しつつ、よりコンパクト化(小型化)した排水溝が求められているのが現状である。
そこで、例えば特許文献1、2には、重量や設置時の掘削量を低減することを可能にした鋼製の排水路が提案されている。
2. Description of the Related Art Conventionally, a concrete drainage channel (drainage channel) is known. However, in the case of concrete products, the weight is heavy and the concrete thickness is thick, and there is a problem of uneconomical and irrational, such as an increase in excavation amount due to a large product size in order to secure a necessary inner space section.
In particular, this problem becomes more prominent, such as the size of the hollow section of mountain tunnels and box culverts increasing according to the height of the drainage gutters. At present, there is a demand for a more compact (miniaturized) drain ditch while maintaining the above.
Therefore, for example, Patent Literatures 1 and 2 propose a steel drainage channel capable of reducing the weight and the amount of excavation during installation.

また、特許文献3、4には、アスファルト止めの機能を付与したL型のものや、コンクリート製の排水路において、清掃頻度の低減や下水処理負荷の低減を目的に、集水する部分と、集水した水の泥を分離して泥等を含まない水を排水する部分とを別々に有する分離型の側溝等、種々の機能を付与した排水路も提案されている。   Patent Literatures 3 and 4 disclose L-shaped ones having a function of stopping asphalt, and a part for collecting water for the purpose of reducing the frequency of cleaning and reducing the load on sewage treatment in a drainage channel made of concrete. There have also been proposed drainage channels provided with various functions, such as a separation type side gutter having a portion for separating the collected water mud and draining water not containing mud or the like separately.

特許第5153908号公報Japanese Patent No. 5153908 特許第4112553号公報Japanese Patent No. 4112553 特許第2791626号公報Japanese Patent No. 2971626 特許第3106307号公報Japanese Patent No. 3106307

前記した鋼製の排水溝で実施するにあたり、その断面を大きくすると、板厚が薄い場合は強度が不足するという問題がある。特に矩形断面の場合、幅寸が大きい場合には強度不足になりやすい。また、鋼製の場合、正方形を含む矩形断面、円形断面のような断面形状であれば既存製品として広く存在する他、容易に製造できるが、これ以外の断面形状や上記分離型といった断面を一体に成形することは至難である。
さらに、前記従来の側溝において、側溝の仕切りの上部に通水孔を設けて、集水部と排水部を分離するだけでは、重力により沈降しなかった集水部の泥やごみが排水側にそのまま流れ込んでしまい、泥やごみと水とを十分に分離できない問題もある。
When carrying out the above-described process using the steel drainage ditch, there is a problem that if the cross section is enlarged, the strength is insufficient when the plate thickness is thin. In particular, in the case of a rectangular cross section, the strength tends to be insufficient when the width is large. In the case of steel, any cross-sectional shape such as a rectangular cross-section including a square or a circular cross-section is widely available as an existing product, and can be easily manufactured. It is extremely difficult to mold the material.
Furthermore, in the conventional side gutter, by merely providing a water passage hole above the partition of the side gutter and separating the water collecting portion and the drainage portion, mud and debris of the water collecting portion that did not settle due to gravity are discharged to the drainage side. There is also a problem that the water flows as it is and the mud or garbage cannot be sufficiently separated from water.

本発明は、上記課題に鑑みて案出されたものであり、その目的とするところは、集水と排水の機能を別々に保有させた2種の鋼管を組み合わせることにより、排水性に優れ、強度を保持しつつコンパクト化を実現できる鋼製排水溝を提供することにある。   The present invention has been devised in view of the above problems, and aims to combine two types of steel pipes having different functions of water collection and drainage, thereby having excellent drainage properties. It is an object of the present invention to provide a steel drainage ditch capable of achieving compactness while maintaining strength.

本発明に係る鋼製排水溝によれば、以下の効果を奏する。
集水用角形鋼管と排水用角形鋼管との組み合わせに係る効果
コンクリート製に比べ小型サイズの集水用と排水用の2種の角形鋼管が、排水機能を保持して結合される構成なので、コンパクトな排水溝を実現できる。
各角形鋼管は入手や製造が容易なので経済的である。しかも、多層構造(合成構造)とすることで、1部材の断面幅方向の長さが短くなり、単層構造と比べ、上載荷重に対し強度・剛性に優れている。
道路表面から侵入した泥等が集水用角形鋼管にのみ流れ込み、排水用角形鋼管へは泥等を含まない流水(水)を自然に選別して流入させることができるので、排水用角形鋼管において泥等の堆積による流量の減少を防止できる等、品質に優れた排水溝を実現できる。
具体的には、集水用角形鋼管の排水孔が、排水用角形鋼管の通水孔よりも小さく形成され、かつ多数(無数に)設けられているので、仮に各孔同士の芯が一致していなくても全体的には排水用角形鋼管へ通水でき、道路表面から流入した泥等が排水用角形鋼管へは侵入し難い排水溝を実現できる。また、仮に集水用角形鋼管内で重力により沈降せず浮遊するような泥やゴミであっても、集水用角形鋼管の排水孔を小さく形成することにより、排水用角形鋼管への流入を阻止できるので、良好な排水性能を発揮できる。
(2)集水用角形鋼管と排水用角形鋼管との結合手段に係る効果
集水用角形鋼管と排水用角形鋼管とは、溶接や接着剤、ボルトや結束バンド等により面タッチ状態で結合されているので、集水用角形鋼管の排水孔から排水用角形鋼管の通水孔へと通水が行われる。
集水用角形鋼管と排水用角形鋼管とをボルトや結束バンド等の非溶着手段で結合する場合は、個々の鋼管は比較的軽量なので、取り回しが容易であり、各鋼管を別々に取り替えることができる。これに伴い、必要な鋼管のみ取り出すことができるので、取替え時の掘削も必要最小限で済む。しかも、個々の鋼管を別々に搬送できるので、輸送効率が良い。 集水用角形鋼管と排水用角形鋼管とを溶接や接着剤等の溶着手段で結合した場合、両者が一体化されるため、耐荷重性に非常に優れている。
The steel drain according to the present invention has the following effects.
Effect of combination of square steel pipe for water collection and square steel pipe for drainage Two types of square steel pipes for water collection and drainage, which are smaller in size than concrete, are combined while retaining the drainage function. A simple drain can be realized.
Each square steel pipe is economical because it is easy to obtain and manufacture. In addition, the multi-layer structure (composite structure) reduces the length of one member in the cross-sectional width direction, and is superior in strength and rigidity to an overload as compared with a single-layer structure.
Mud, etc. that has invaded from the road surface flows only into the rectangular steel pipe for water collection, and the running water (water) that does not contain mud etc. can be naturally selected and flowed into the rectangular steel pipe for drainage. It is possible to realize a high-quality drain ditch, for example, preventing a decrease in flow rate due to accumulation of mud and the like.
Specifically, the drainage holes of the rectangular steel pipe for water collection are formed smaller than the water holes of the rectangular steel pipe for drainage, and a large number (innumerable) are provided. Even if it is not, water can be passed through the drainage square steel pipe as a whole, and a drain can be realized in which mud or the like flowing from the road surface is unlikely to enter the drainage square steel pipe. In addition, even if mud or debris that floats without sedimentation due to gravity in the rectangular steel pipe for collecting water, the drainage rectangular steel pipe can be made to flow into the rectangular steel pipe for draining by forming a small drain hole. Because it can be prevented, good drainage performance can be exhibited.
(2) Effects of the joining means between the rectangular steel pipe for collecting water and the rectangular steel pipe for draining The rectangular steel pipe for collecting water and the rectangular steel pipe for draining are joined in a surface touch state by welding, an adhesive, a bolt, a binding band, or the like. Therefore, water flows from the drainage holes of the rectangular steel pipe for collecting water to the water holes of the rectangular steel pipe for drainage.
When connecting the rectangular steel pipe for water collection and the rectangular steel pipe for drainage by non-welding means such as bolts and binding bands, the individual steel pipes are relatively lightweight, so it is easy to handle and it is possible to replace each steel pipe separately. it can. Accordingly, only necessary steel pipes can be taken out, so that excavation at the time of replacement can be minimized. Moreover, since the individual steel pipes can be transported separately, the transportation efficiency is good. When the rectangular steel pipe for water collection and the rectangular steel pipe for drainage are joined by welding or welding means such as an adhesive, the two are integrated, so that they are extremely excellent in load resistance.

The significance of the staggered arrangement is to efficiently collect water flowing down, such as rainwater, and to rationally suppress a decrease in strength of the rectangular steel pipe 2 for collecting water. However, the form of the water collecting hole 3 is not limited to the illustrated example, and the design can be changed as appropriate. In short, it is only necessary that the reduction in the strength of the steel pipe can be rationally suppressed and efficient water collection can be realized.

前記集水孔3の配置(穿設部位)は、図1では、前記集水用角形鋼管2の上面20にのみ設けて実施しているがこれに限定されず、前記集水用角形鋼管2の設置状況に応じて種々のバリエーションで実施可能である。
例えば、図8では、前記集水用角形鋼管2の上面20のほか、前記集水用角形鋼管2の側面21における前記排水用角形鋼管5の上面50よりも高い部位に集水孔3を設けて実施している。
また、前記集水用角形鋼管2の上面20に設ける集水孔3に代えて、前記集水用角形鋼管2の側面21における前記排水用角形鋼管5の上面50よりも高い部位に集水孔3を設けて実施することもできる。すなわち、この場合は上面20が閉塞され、側面21が開口された集水用角形鋼管2で実施される。
さらに、図示は省略するが、前記排水用角形鋼管5との非当接部位である前記集水用角形鋼管2の側面22に集水孔を設けて実施することもできる。この構成は、前記側面22に接する縁石10等の部材が透水性を有する場合に効果的に集水できる利点がある。
In FIG. 1, the arrangement (perforation site) of the water collecting holes 3 is provided by being provided only on the upper surface 20 of the rectangular steel pipe 2 for collecting water, but the present invention is not limited to this. It can be implemented in various variations according to the installation situation of.
For example, in FIG. 8, in addition to the upper surface 20 of the rectangular steel pipe 2 for collecting water, the water collecting hole 3 is provided at a position higher than the upper surface 50 of the rectangular steel pipe 5 for drainage on the side surface 21 of the rectangular steel pipe 2 for collecting water. Has been implemented.
Further, instead of the water collecting hole 3 provided on the upper surface 20 of the rectangular steel pipe 2 for collecting water, a water collecting hole is formed on a side surface 21 of the rectangular steel pipe 2 for collecting water higher than the upper surface 50 of the rectangular steel pipe 5 for draining. 3 may be provided and practiced. That is, in this case, the water collecting square steel pipe 2 having the upper surface 20 closed and the side surface 21 opened is implemented.
Although not shown, a water collecting hole may be provided on the side surface 22 of the water collecting rectangular steel pipe 2 which is a non-contact portion with the drainage rectangular steel pipe 5. This configuration has an advantage that water can be effectively collected when a member such as the curb 10 in contact with the side surface 22 has water permeability.

前記集水用角形鋼管2の排水孔4は、排水用角形鋼管5の通水孔6よりも小さく形成されている。当接される両孔4、6同士を重なり合せて排水性を良くすると共に、集水用角形鋼管2へ流入した泥やゴミ、さらに言えば重力により沈降せず浮遊するような泥がゴミを排水用角形鋼管5に流れ込ませないためである。
前記排水孔4は、図2A、図4Aに示した円形状(一例として、φ=10mm程度)のものや、図3Aに示した縦長の長円形状(一例として、長軸65mm程度、短軸10mm程度)のものが好適である。
本実施例では、図2A、図4Aの円形状タイプの排水孔4の場合、縦方向の1列に3箇所又は2箇所ずつ、水の流れ方向に40mm程度の間隔で複数設けられている。図3Aの長円形状タイプの排水孔4の場合、水の流れ方向に40mm程度の間隔で複数設けられている。
ちなみに本実施例に係る排水孔4は、その最下レベルを前記集水用角形鋼管2の下面23から63mm程度上方の位置に設定している。これは、集水孔3から集水用角形鋼管2内へ流入された泥やゴミを含む流下物が鋼管延長方向へ流下する過程において、その泥やゴミが自重で集水用角形鋼管2内に経時的に沈降し、排水孔4から排水用角形鋼管5への流出を可及的に防ぐことに寄与する。
The drain hole 4 of the rectangular steel pipe 2 for collecting water is formed smaller than the water passage hole 6 of the rectangular steel pipe 5 for drain. The abutting holes 4 and 6 overlap each other to improve drainage, and at the same time, mud and debris flowing into the rectangular steel pipe 2 for collecting water, and more particularly, mud that floats without settling due to gravity. This is because it is not allowed to flow into the rectangular steel pipe 5 for drainage.
The drain hole 4 has a circular shape (for example, about φ = 10 mm) shown in FIGS. 2A and 4A, or a vertically long oval shape (for example, about 65 mm long axis and short axis shown in FIG. 3A). (Approximately 10 mm) is preferable.
In the present embodiment, in the case of the circular drain holes 4 shown in FIGS. 2A and 4A, a plurality of drain holes 4 are provided at three places or two places in one row in the vertical direction at intervals of about 40 mm in the water flow direction. In the case of the oval drain hole 4 of FIG. 3A, a plurality of drain holes 4 are provided at intervals of about 40 mm in the flow direction of water.
Incidentally, the lowermost level of the drain hole 4 according to the present embodiment is set at a position approximately 63 mm above the lower surface 23 of the rectangular steel pipe 2 for collecting water. This is because, in the process in which the falling material including the mud and the dust flowing into the water collecting square steel pipe 2 from the water collecting hole 3 flows down in the steel pipe extension direction, the mud and the dust are owed to the gravity of the water collecting rectangular steel pipe 2 by their own weight. And sedimentation over time, which contributes to preventing the outflow to the drainage rectangular steel pipe 5 from the drainage hole 4 as much as possible.

一方、前記排水用角形鋼管5は、前記集水用角形鋼管2と同様に、矩形断面の鋼製角形鋼管で実施され、その一方の側面52に、前記集水用角形鋼管2の排水孔4に連通する通水孔6が設けられている。
ちなみに、本実施例に係る排水用角形鋼管5は、一例として、幅寸(W2)が250mm程度、高さ(H2)が150mm程度、奥行きが1000mm程度、板厚が6.0mm程度で実施されている。もとより、奥行き方向(鋼管延長方向)には、必要な長さ(通常、集水用角形鋼管2と同等長さ)に達するまで適宜継ぎ足して連続している。もちろん、この排水用角形鋼管5の形態は、これに限定されず、適宜設計変更可能である。
On the other hand, the rectangular steel pipe 5 for drainage is implemented by a rectangular steel pipe having a rectangular cross section like the rectangular steel pipe 2 for collecting water, and the drain hole 4 of the rectangular steel pipe 2 for collecting water is formed on one side surface 52. Is provided with a water passage hole 6 communicating with.
By the way, the rectangular steel pipe for drainage 5 according to the present embodiment is implemented, for example, with a width (W2) of about 250 mm, a height (H2) of about 150 mm, a depth of about 1000 mm, and a thickness of about 6.0 mm. ing. Of course, in the depth direction (extending direction of the steel pipe), the pipe is continuously extended as needed until it reaches a required length (usually the same length as the rectangular steel pipe 2 for collecting water). Of course, the form of the rectangular steel pipe 5 for drainage is not limited to this, and the design can be changed as appropriate.

前記排水用角形鋼管5の通水孔6は、前記集水用角形鋼管2の排水孔4よりも若干大きく形成されている。この通水孔6は、図2B、図3Bに示した縦長の長円形状(長軸65mm程度、短軸20mm程度)のものや、図4Bに示した円形状のもの(φ=15mm程度)が好適である。
図2B、図3Bの長円形状タイプの通水孔6の場合、水の流れ方向に30mm間隔で複数設けられている。縦長の長円形で実施する意義は、強度低下を抑えつつ、開口面積を広く確保できることにある。図4Bの円形状タイプの通水孔6の場合、縦方向の1列に3箇所又は2箇所ずつ、水の流れ方向に35mm程度の間隔で複数設けられている。
ちなみに本実施例に係る通水孔6は、その最下レベルを、前記排水孔4に略合致するよう、前記排水用角形鋼管5の下面53から63mm程度上方の位置に設定している。
この排水用角形鋼管5の通水孔6は、上記のように側面52の上方に大きな孔とせず中程度の孔とし、さらに等間隔で設けることにより強度が保持される。
なお、この排水用角形鋼管5の上面50に集水孔7を設けて実施することもできる。道路1を透水性舗装で実施する場合の集水を可能とするためである。
The water hole 6 of the drainage rectangular steel pipe 5 is formed slightly larger than the drainage hole 4 of the water collection rectangular steel pipe 2. The water passage hole 6 has a vertically long oval shape (about 65 mm long axis and about 20 mm short axis) shown in FIGS. 2B and 3B or a circular shape shown in FIG. 4B (about φ = 15 mm). Is preferred.
In the case of the elliptical water holes 6 shown in FIGS. 2B and 3B, a plurality of water holes 6 are provided at intervals of 30 mm in the water flow direction. The significance of using a vertically long oval is that a wide opening area can be secured while suppressing a decrease in strength. In the case of the circular type water holes 6 shown in FIG. 4B, a plurality of water holes are provided at three places or two places in one row in the vertical direction at intervals of about 35 mm in the water flow direction.
Incidentally, the lowermost level of the water passage hole 6 according to the present embodiment is set at a position about 63 mm above the lower surface 53 of the drainage rectangular steel pipe 5 so as to substantially coincide with the drainage hole 4.
The water passage holes 6 of the drainage rectangular steel pipe 5 are not large holes above the side surface 52 as described above, but are medium holes, and are provided at equal intervals to maintain strength.
In addition, the water collecting hole 7 can be provided in the upper surface 50 of the rectangular steel pipe 5 for drainage, and the embodiment can be implemented. This is to enable water collection when the road 1 is implemented by permeable pavement.

上述したように、前記集水用角形鋼管2の排水孔4と排水用角形鋼管5の通水孔6は、図3と図4に示すように、同一形状の実施形態のほか、図2のように互いに形状が異なる実施形態でも好適に実施される。ゴミや汚泥の流出を防止して通水性を確保するために、相対的に排水孔4が通水孔6よりも小さく形成されていれば適宜設計変更可能である。
前記排水孔4と通水孔6の形態(形状、大きさ)のバリエーションは種々考えられるが、要は、排水孔2、通水孔6に求められる排水性(通水性)を発揮するために必要な開口面積(開口率)を達成しつつ、上載荷重に対して十分に抵抗し耐える強度・剛性を備えた構成、さらに言えば各角形鋼管2、5の開口部による断面欠損に起因する断面係数および断面二次モーメントの低下を効果的に抑制できる構成であれば開口部(排水孔4、通水孔6)の形態や組み合わせは図示例に限定されず、適宜設計変更可能である。
なお、上記した図10、図11の実施例に係る鋼製排水溝の排水孔4、通水孔6についても同様の技術的思想に基づいて形成されるので、同一の符号を付してその説明を省略する(図2〜図4を援用して参照)。
As described above, the drain holes 4 of the rectangular steel pipe 2 for collecting water and the water holes 6 of the rectangular steel pipe 5 for drainage have the same shape as shown in FIGS. As described above, the embodiments having different shapes are preferably implemented. In order to prevent outflow of dust and sludge and ensure water permeability, the design can be appropriately changed as long as the drain hole 4 is formed relatively smaller than the water passage hole 6.
Various variations in the form (shape, size) of the drain hole 4 and the water passage hole 6 are conceivable, but the point is that in order to exhibit the drainage (water permeability) required for the drain hole 2 and the water passage hole 6. A structure with sufficient strength and rigidity to achieve the required opening area (opening ratio) and sufficiently resist and withstand the overload, more specifically, the cross-section due to the cross-sectional defect due to the opening of each of the square steel pipes 2 and 5 The configuration and combination of the openings (the drain holes 4 and the water holes 6) are not limited to the illustrated examples as long as the configuration can effectively suppress the reduction of the coefficient and the second moment of area, and the design can be changed as appropriate.
Since the drain holes 4 and the water holes 6 of the steel drain grooves according to the embodiment of FIGS. 10 and 11 are formed based on the same technical idea, the same reference numerals are given. The description is omitted (see FIGS. 2 to 4 with the help).

かくして、本実施例に係る鋼製排水溝は、前記集水用角形鋼管2の側面21と排水用角形鋼管5の側面52同士が当接して結合状態とされたとき、集水用角形鋼管2と排水用角形鋼管5との合算した幅寸(W1+W2)は350mmとコンパクト化して実現できる。ちなみに、一例として350mmに設定した意義は、白線の外縁端から縁石までの幅寸が350mmに設定されている道路1が多いことに基づいている。もとより、幅寸はこれに限定されるものではなく、適宜設計変更可能である。
結合した際、集水用角形鋼管2の排水孔4が、排水用角形鋼管5の通水孔6より小さく形成されているので、排水孔4から通水孔6へ通水される上に、道路1表面から流入した泥やゴミが排水孔4から通水孔6へ侵入しづらい構成となっている。
当接された両鋼管2、5の結合手段は、溶接や接着剤によるほか、図5に示したような両端部近傍に配置したボルト8により接合される。当接面にはパッキン等(図示省略)を介在させるのが好ましい。
Thus, the steel drainage groove according to the present embodiment, when the side surface 21 of the rectangular steel pipe 2 for collecting water and the side surface 52 of the rectangular steel pipe 5 for drainage are brought into contact with each other and connected to each other, the rectangular steel pipe 2 for collecting water. And the combined width (W1 + W2) of the drainage rectangular steel pipe 5 can be reduced to 350 mm and realized. Incidentally, the significance of setting to 350 mm as an example is based on the fact that there are many roads 1 in which the width from the outer edge of the white line to the curb is set to 350 mm. Of course, the width is not limited to this, and the design can be changed as appropriate.
When combined, the drainage hole 4 of the rectangular steel pipe 2 for collecting water is formed smaller than the water hole 6 of the rectangular steel pipe 5 for drainage. The structure is such that mud and debris flowing from the surface of the road 1 are hard to enter the water hole 6 from the drain hole 4.
The connecting means of the two steel pipes 2 and 5 which are in contact with each other is joined by a bolt 8 arranged near both ends as shown in FIG. It is preferable that packing or the like (not shown) is interposed on the contact surface.

或いは、図6と図7に示したように、結束バンド9により結合して実施することもできる。図6は、当接しない側の集水用角形鋼管2の側面22と排水用角形鋼管5の側面51間に跨る上向きコ字状の結束バンド9が、集水用角形鋼管2と排水用角形鋼管5の下方から係止されている。
図6A、Bに示す結束バンド9は、集水用角形鋼管2の下面23と排水用角形鋼管5の下面53にわたる帯状下部9aと、その帯状下部9aの両端部から上方に立ち上がる垂直部9b、9cを備えている。垂直部9bにより集水用角形鋼管2の側面22が係止され、垂直部9cにより排水用角形鋼管5の側面51が係止されることにより、当接された集水用角形鋼管2と排水用角形鋼管5とが結合されている。
具体的に、図6Aに示す結束バンド9の垂直部9cは、排水用角形鋼管5の側面51方向に若干突き出て弾性変形により係止されている。図6Bに示す結束バンド9の垂直部9cは、排水用角形鋼管5の側面51に当接して弾性変形すると共に、上面50をも拘束可能なL字状に形成され、前記側面51をホールドする構成で係止されている。
図7は、トンネル内の監査廊(図示省略)の鉄筋11に、結束バンド9を取り付けた実施形態を示している。結束バンド9の垂直部9bが、その上端において鉄筋11方向に屈曲した水平部9b’に形成されたL字状をなしている。その水平部9b’には貫通孔90が設けられ、前記鉄筋11に接続されたL字部材12の屈曲された上向き先端が、前記貫通孔90に下方から嵌挿されて、結束バンド9により結合された集水用角形鋼管2と排水用角形鋼管5とが位置決め固定されている。
Alternatively, as shown in FIG. 6 and FIG. FIG. 6 shows an upside-down U-shaped tying band 9 extending between the side surface 22 of the rectangular steel pipe 2 for collecting water and the side 51 of the rectangular steel pipe 5 for drainage on the non-contacting side. It is locked from below the steel pipe 5.
The binding band 9 shown in FIGS. 6A and 6B includes a band-shaped lower portion 9a extending over the lower surface 23 of the rectangular steel tube 2 for collecting water and the lower surface 53 of the rectangular steel tube 5 for drainage, and a vertical portion 9b rising upward from both ends of the band-shaped lower portion 9a. 9c. The vertical portion 9b locks the side surface 22 of the water collecting rectangular steel pipe 2, and the vertical portion 9c locks the side surface 51 of the drainage rectangular steel pipe 5, so that the water collecting rectangular steel tube 2 and the drainage rectangular steel tube 2 that are in contact with each other. And the square steel pipe 5 for use.
Specifically, the vertical portion 9c of the binding band 9 shown in FIG. 6A slightly protrudes in the direction of the side surface 51 of the rectangular steel pipe 5 for drainage and is locked by elastic deformation. The vertical portion 9c of the binding band 9 shown in FIG. 6B abuts against the side surface 51 of the rectangular steel pipe 5 for drainage and is elastically deformed. Locked in configuration.
FIG. 7 shows an embodiment in which a binding band 9 is attached to a reinforcing bar 11 of an inspection corridor (not shown) in a tunnel. The vertical portion 9b of the binding band 9 has an L-shape formed at the upper end thereof at a horizontal portion 9b 'bent toward the reinforcing bar 11. A through hole 90 is provided in the horizontal portion 9 b ′, and a bent upward end of the L-shaped member 12 connected to the reinforcing bar 11 is inserted into the through hole 90 from below and joined by the binding band 9. The collected rectangular steel pipe 2 for water collection and the rectangular steel pipe 5 for drainage are positioned and fixed.

なお、前記結束バンド9は、鋼管の中空断面方向からみて上向きコ字状で実施しているがこれに限定されず、下向きコ字状、或いは鋼管全体を囲繞する構成でも同様に実施できる。要は、鋼製排水溝全体を合一に結合できる結束バンド9であれば形態は問わない。
ちなみに前記結束バンド8による結合手段は、前記した溶接又は接着剤又はボルトによる結合手段に加えて実施することも勿論できる。
The binding band 9 is formed in an upward U-shape when viewed from the direction of the hollow section of the steel pipe. However, the present invention is not limited to this, and it can be similarly implemented in a downward U-shape or a configuration surrounding the entire steel pipe. In short, the form is not limited as long as the binding band 9 can unite the entire steel drainage groove.
Incidentally, the connecting means by the binding band 8 can of course be implemented in addition to the above-mentioned connecting means by welding, adhesive or bolt.

図8には具体的実施例を示した。この実施例では、集水用角形鋼管2と排水用角形鋼管5とが結合されて成る鋼製排水溝を、道路1の側端において縁石10に隣接され、道路1の白線(図示省略)の外方に排水用角形鋼管5の側面51が配置されるように、鋼管延長方向に複数継ぎ足して設置する。本実施例のように、集水用角形鋼管2と排水用角形鋼管5との合算幅寸を350mmに設定した場合は、鋼製排水溝全体を白線の外方に収めることが可能となる。
しかる後、排水用角形鋼管5の上面50から集水用角形鋼管2の側面21へ至る透水性のアスファルト1(道路)が施工される。なお、図9のように、集水用角形鋼管2をアスファルト1の表面よりも高く形成し、縁石10の一部として使用することも可能である。
FIG. 8 shows a specific embodiment. In this embodiment, a steel drain groove formed by connecting a rectangular steel pipe 2 for collecting water and a rectangular steel pipe 5 for drainage is provided adjacent to a curb 10 at a side end of the road 1 and is formed with a white line (not shown) of the road 1. In order to arrange the side surface 51 of the rectangular steel pipe 5 for drainage outward, a plurality of pipes are added and installed in the steel pipe extension direction. When the total width of the rectangular steel pipe for water collection 2 and the rectangular steel pipe for drainage 5 is set to 350 mm as in the present embodiment, the entire steel drainage groove can be accommodated outside the white line.
Thereafter, the permeable asphalt 1 (road) from the upper surface 50 of the drainage rectangular steel pipe 5 to the side face 21 of the water collecting rectangular steel pipe 2 is constructed. As shown in FIG. 9, it is also possible to form the water collecting rectangular steel pipe 2 higher than the surface of the asphalt 1 and use it as a part of the curb 10.

したがって、鋼製排水溝の集水用角形鋼管2と排水用角形鋼管5とは、面タッチ状態で結合されているので、集水孔3から集水用角形鋼管2内へ流入された泥やゴミを含む流下物が鋼管延長方向へ流下する過程において、両鋼管2、5の隙間に水が流出することなく、集水孔3を通じて集水用角形鋼管2に集まった流下物中の流水(雨水、スプリンクラーの水、湧き水、山水等)が、排水孔4から排水用角形鋼管排水部5の通水孔6へと通水が行われる。泥やゴミは集水用角形鋼管2に沈降され、排水用角形鋼管5に流入されることはない。仮に、集水用角形鋼管2内で重力により沈降せず浮遊するような泥やゴミであっても、集水用角形鋼管2の排水孔4を小さく形成することにより、排水用角形鋼管5への流入を阻止できるので、良好な排水性能を発揮することができる。   Therefore, the rectangular steel pipe 2 for collecting water and the rectangular steel pipe 5 for draining in the steel drainage ditch are connected in a face touch state, so that the mud flowing into the rectangular steel pipe 2 for collecting water from the water collecting hole 3 is removed. In the process in which the falling material including garbage flows down in the direction in which the steel pipes extend, water does not flow out into the gap between the steel pipes 2 and 5, and the flowing water ( Rainwater, sprinkler water, spring water, mountain water, etc.) flow from the drainage hole 4 to the drainage hole 6 of the rectangular steel pipe drainage part 5 for drainage. Mud and dust are settled in the rectangular steel pipe 2 for collecting water and do not flow into the rectangular steel pipe 5 for drainage. Even if mud or dust that floats without settling due to gravity in the water collecting rectangular steel pipe 2, the drainage rectangular steel pipe 5 can be formed by forming the drainage hole 4 of the water collecting rectangular steel pipe 2 small. Since the inflow of water can be prevented, good drainage performance can be exhibited.

以上、実施例を図面に基づいて説明したが、本発明は、図示例の限りではなく、その技術的思想を逸脱しない範囲において、当業者が通常に行う設計変更、応用のバリエーションの範囲を含むことを念のために言及する。   Although the embodiments have been described with reference to the drawings, the present invention is not limited to the illustrated examples, and includes a range of design changes and application variations that are normally performed by those skilled in the art without departing from the technical idea thereof.
