【考案の詳細な説明】
本考案はプラスチツクパイプを敷設する際、配
管レベルを容易に設定できると共に、管の支承が
安定する埋設配管用枕台に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bed for buried pipes that allows for easy setting of the pipe level and stable support for the pipes when laying plastic pipes.
従来から使用されている木製、或いはコンクリ
ート製の枕台では、プラスチツクパイプ等を埋設
後枕台の当接箇所が部分的になり、その部分に荷
重が集中して、変形したり、破損を生ずる虞れが
あつた。 With conventionally used wooden or concrete bed rests, after burying plastic pipes, the contact points of the bed rest become partial, and the load concentrates on that part, causing deformation or damage. I was afraid.
また、上記枕台として土のうを用いる場合もあ
るが土のうの内部の砂と外部の土砂とは袋体を介
して隔絶しているため、そこに密度差を生じて結
果的には上記木製やコンクリート製の枕台のよう
にパイプに固体が接触している状態に近いものと
なる。 In addition, sandbags are sometimes used as the pillow base, but since the sand inside the sandbag and the earth and sand outside are separated by the bag, there is a density difference, and as a result, the wooden or concrete The situation is similar to that of a solid body in contact with a pipe, such as in a wooden pillow stand.
本考案は、上記問題を解消するものであつて、
その要旨は、水溶性プラスチツクよりなる袋体内
に土砂を封入してなる埋設配管用枕台である。 The present invention solves the above problems, and includes:
The gist of the product is a pillow stand for buried piping, which is made by enclosing earth and sand in a bag made of water-soluble plastic.
以下図面により実施例を説明する。 Examples will be described below with reference to the drawings.
第１図は本考案の枕台の一例を示す一部切欠斜
視図であり、第２図は本考案の他の例を示すもの
であり、第３図は、本考案品の施工状態を示す略
図である。 Fig. 1 is a partially cutaway perspective view showing an example of the pillow stand of the invention, Fig. 2 shows another example of the invention, and Fig. 3 shows the construction state of the product of the invention. This is a schematic diagram.
１は枕台、２は袋体、３は砂、４はパイプを
夫々示す。 1 is a pillow stand, 2 is a bag body, 3 is sand, and 4 is a pipe.
袋体２を構成する水溶性プラスチツクとして
は、ポリビニルアルコール、ポリビニルホルマー
ル、メチルセルロースなど水と接触して溶解する
ものであり、枕台１は該水溶性プラスチツクを第
１図のような袋状乃至第２図のような管の座りを
よくした形態等の袋体２に予め成形しておき、こ
れに砂３を入れて密封したものである。 The water-soluble plastics constituting the bag body 2 include polyvinyl alcohol, polyvinyl formal, methyl cellulose, etc., which dissolve when they come into contact with water. A bag 2, such as the one shown in Fig. 2 in which the tube sits well, is formed in advance, and sand 3 is poured into the bag and the bag is sealed.
上記本考案品を配管施工に使用する場合、第３
図に示す如く所定の配管レベルに合わせ、枕台１
を所定間隔にパイプ４の下に敷き、覆土して水締
めを行なうと、土中の水分により、枕台１の袋体
２が徐々に溶解し、枕台１の内部にあつた砂と、
外部の土砂５とが無理なく自然に一体化するの
で、埋設管に部分的な応力の集中が起らず、従つ
て、埋設管が変形したり破損することがなく、配
管施工上効果のすぐれた枕台である。 When using the above invented product for piping construction, the third
As shown in the figure, set the pillow base 1 according to the predetermined piping level.
When the pipes 4 are placed under the pipes 4 at predetermined intervals and covered with soil, the bag body 2 of the pillow base 1 gradually dissolves due to moisture in the soil, and the sand inside the pillow base 1 is removed.
Since the external earth and sand 5 are naturally integrated with each other, local stress concentration does not occur in the buried pipe, and therefore the buried pipe is not deformed or damaged, which is highly effective in piping construction. It is a pillow stand.
