【発明の詳細な説明】 〔産業上の利用分野〕 本発明は石炭等の資源を備蓄する目的で設営した貯蔵
所に於いて、周囲に発生する塵害、砂害又は雪害等を防
止する装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for preventing dust, sand, snow, and the like from being generated in a storage facility established for stockpiling resources such as coal. It is about.
石炭等の資源を大規模に備蓄する貯蔵所に於いて、防
塵・防砂・防雪を目的とする従来装置は、貯蔵所の周囲
（境界）に柵（網状のネット、遮蔽板又は有孔板等も含
む）を設置した構造物としたものが知られている。In a storage facility that stores coal and other resources on a large scale, conventional equipment designed to prevent dust, sand, and snow requires a fence (net-like net, shielding plate, perforated plate, etc.) around the storage (boundary). Is also known.
貯蔵所の規模は、周囲数キロメートル、或は十数キロ
メートルに及ぶものがあり、周囲又は一方向の風に対す
る上記防塵等の構造物も必然的に長大なものとなる。The size of the storage area may be several kilometers or several tens of kilometers around, and the structure such as the above-described dust proof against the wind in the surrounding or one-way direction is necessarily long.
一方、柵に於ける塵等の害の原因である風の減風効果
を得られる範囲は、柵の高さのおよそ10乃至15倍の距離
であり、減風域を広くするためには高い柵の構築が望ま
れる。On the other hand, the range in which the wind-reducing effect of the wind, which causes harm such as dust on the fence, can be obtained is about 10 to 15 times the height of the fence, which is high for widening the wind-reducing area. Construction of fence is desired.
しかし、例えば、大規模な石炭貯蔵所では、周囲の柵
に減風効果を期待するとすれば、百メートル以上の高さ
の柵が必要であり、構造的にも設備費的にも困難である
と共に、美観上も問題となる。However, for example, in a large-scale coal depot, if the surrounding fences are expected to have a wind-reducing effect, fences with a height of 100 meters or more are necessary, which is difficult both structurally and in terms of equipment costs. At the same time, aesthetics are also a problem.
更に、備蓄は石炭を積み上げ、多数の山を造る形態で
行われるため、風が山の斜面に沿って上昇し、砂塵等を
吹き上げると共に、横風による吹き払い現象が生じ、風
下の柵を越えて飛散し、従って、柵は高いほど防塵等の
効果がある。Furthermore, since stockpiling is carried out in the form of stacking coal and building a large number of mountains, the wind rises along the slopes of the mountains, blowing up dust and the like, and the phenomenon of blowing off by the crosswind occurs, crossing the downwind fence. Scattering, therefore, the higher the fence, the more dust-proofing and other effects.
又、貯蔵敷地内に柵を設けて上昇風或は横風等を防止
することも考えられるけれども、敷地内での恒久的な柵
の設置は、貯蔵物の運搬作業に支障となり、好ましくな
いのである。Also, it is conceivable to provide a fence in the storage premises to prevent upward wind or crosswind, etc., but installing a permanent fence in the premises will hinder the work of transporting the stored items, which is not preferable. .
そこで、本発明は柵の高さを低めに保てると共に、貯
蔵所内に生ずる上昇風及び横風等をも減速可能な装置を
提供することを目的とする。Accordingly, an object of the present invention is to provide a device that can keep the height of the fence low and can also reduce the updraft and crosswind generated in the storage.
本発明は貯蔵所の境界に外柵を設置すると共に、貯蔵
山の頂部に内柵を設置したものであり、内柵は移動可能
に設置することもできる。According to the present invention, the outer fence is installed at the boundary of the storage, and the inner fence is installed at the top of the storage mountain. The inner fence can be movably installed.
内柵を設置する頂部は、貯蔵山の頂上又は頂上近くの
斜面上部であってもよい。The top where the inner fence is installed may be at the top of the storage mountain or at the top of the slope near the top.
次に本発明の作用を説明する。 Next, the operation of the present invention will be described.
先ず、外柵に当たる風は減速され、貯蔵敷地内へ入
り、又、外柵上方の風は、そのままで風勢で進む。First, the wind hitting the outer fence is decelerated and enters the storage premises, and the wind above the outer fence proceeds with the wind as it is.
減速された風は、徐々に風力を回復しながら貯蔵山の
斜面に沿って上昇し、外柵上方を通った風と合流するの
であるが、貯蔵山の頂部に設置した内柵に当たり、通過
する際に減速すると共に、運んできた塵、砂、雪等を内
柵の前後部へ落下せしめるのである。The decelerated wind rises along the slope of the storage mountain while gradually recovering the wind, and merges with the wind that passed above the outer fence, but hits the inner fence installed at the top of the storage mountain and passes In addition to slowing down, dust, sand, snow, etc., which have been carried, fall down to the front and rear of the inner fence.
従って、貯蔵敷地内を通過する外柵によって減速され
た風、貯蔵山の斜面を上昇する風、及び外柵の上方を越
えてきた風は、貯蔵山の頂部に設置した内柵で減風し、
塵、砂、雪等を貯蔵所外へ風で運ばれるのを和らげ、且
つ、防止するのである。Therefore, wind decelerated by the outer fence passing through the storage premises, wind rising on the slope of the storage mountain, and wind passing above the outer fence are reduced by the inner fence installed at the top of the storage mountain. ,
It mitigates and prevents dust, sand, snow, and the like from being carried out of the storage by wind.

構築されるものであるから、移設可能な構造とすること
が望ましく、貯蔵山（２）の表面に化学薬剤を撒布して
固化するのを利用して構築すれば、容易に安定できる。Further, since the inner fence (4) is constructed on the temporarily existing storage mountain (2), it is desirable that the inner fence (4) has a structure that can be relocated, and a chemical agent is sprayed on the surface of the storage mountain (2). It can be easily stabilized if it is constructed by using the solidification.

果を有するものである。As described above, according to the present invention, since the inner fence is provided at the top of the storage mountain together with the outer fence at the boundary of the storage, firstly, it is possible to prevent scattering of dust and the like coming up on the slope of the storage mountain, Second, it has the effect of reducing crosswinds, and secondly, because the inner fence is provided by using a storage mountain, it can be located at a high place without building the inner fence itself high. There is an effect such as the fact that the height of the outer fence can be kept low to some extent and the beauty can be improved, and thirdly, if the inner fence is temporary and installed so that it can be relocated, it will increase or decrease the storage amount and storage mountain In addition, because the inner fence is installed in the storage mountain, there are various effects that the inner fence can be installed without limiting the traffic of vehicles and machinery on the premises and facilities. Things.
