Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は水道管、ガス管等の配管の埋設方法に関する。The present invention relates to a method for burying pipes such as water pipes and gas pipes.
従来、水道管、ガス管等の配管の埋設は第５図に示すよ
うな手順で行われている。Conventionally, the burying of pipes such as water pipes and gas pipes has been performed in the procedure as shown in FIG.
溝８を掘削する。 The groove 8 is excavated.
溝８内に埋戻土10を突き固め、基盤面を形成する。 The backfill soil 10 is tamped in the groove 8 to form a base surface.
基盤面に配管９を敷設する。 The pipe 9 is laid on the base surface.
溝８内の配管の周囲に埋戻土10を層状に突き固め
る。The backfill soil 10 is tamped in layers around the pipe in the groove 8.
場合によっては、最終的に地表面にコンクリートを
打設する。In some cases, concrete is finally placed on the ground surface.
この場合、埋戻土として発生土を用いることはほとんど
なく、川砂や山砂等粒度分布の良い良質の砂が用いられ
る。In this case, the generated soil is rarely used as the backfill soil, and good quality sand such as river sand or mountain sand with good particle size distribution is used.
しかしながら、このような従来の方法には以下の問題が
ある。However, such a conventional method has the following problems.
溝を埋め戻すのに良質の埋戻土（砂）が大量に必要
となるが、近年このような砂は入手困難になってきてい
る。A large amount of good quality backfill soil (sand) is required to refill the trench, but in recent years such sand has become difficult to obtain.
埋戻土の中に礫等を入れてしまった場合は取り除き
が困難となる。If gravel is put in the backfill soil, it will be difficult to remove it.
土砂（埋戻土）自体が重いため、埋戻作業に重機
（バックホー、トラック）が必要となる。Since the earth and sand (backfill soil) itself is heavy, heavy equipment (backhoe, truck) is required for the backfill work.
地盤ひずみが配管に直接伝播するため、地震等によ
り配管が損傷を受け易い。Since the ground strain propagates directly to the pipe, the pipe is easily damaged by an earthquake or the like.
配管の点検、補修の際の掘下げ作業は配管の埋戻し
作業と同様な作業となり、煩雑である。The digging work when inspecting and repairing the pipe is the same as the backfilling work of the pipe, which is complicated.
掘上げ作業時には土砂と配管の区別がつきにくく、
配管を傷めてしまうことがある。When excavating, it is difficult to distinguish between sediment and piping,
It may damage the piping.
本発明はこのような従来の問題を生じることのない新た
な配管埋設方法を提供しようとするものである。The present invention aims to provide a new pipe burying method that does not cause such a conventional problem.
このため、本発明は、掘削した溝に、配管を埋設する方
法において、前記溝のうち表層側の一部を除いてその殆
んどを占めるように、樹脂発泡体のブロックを前記配管
の周囲に配して埋設することをその基本的特徴とする。Therefore, in the present invention, in a method of burying a pipe in an excavated groove, a block of resin foam is provided around the pipe so as to occupy most of the groove except a part on the surface layer side. Its basic feature is to place and bury it.
通常、発泡スチロール等の樹脂発泡体ブロックは、配管
周方向でいくつかの分割ブロックに構成され、埋設構内
で配管を囲むようにして組み付けられる。Usually, a resin foam block such as styrofoam is composed of several divided blocks in the circumferential direction of the pipe, and is assembled so as to surround the pipe in the buried structure.
配管を囲った樹脂発泡体の上部すなわち溝の表層側の一
部には、必要に応じて土砂等が埋め戻される。The upper part of the resin foam surrounding the pipe, that is, a part on the surface layer side of the groove is backfilled with earth and sand as necessary.
樹脂発泡体としては、発泡スチロール以外にも、他の高
分子材料からなる発泡体を用いることができる。As the resin foam, a foam made of another polymer material can be used in addition to the polystyrene foam.
このような本発明の埋設方法は、上下水道、ガス管、石
油等のパイプラインをはじめ、あらゆる配管の埋設に適
用できる。The burying method of the present invention as described above can be applied to burying of various pipes including pipelines for water and sewerage, gas pipes, oil and the like.
第１図は本発明の埋設方法による配管の埋設状態の一例
を示している。図において、１は埋設溝、２は配管であ
る。FIG. 1 shows an example of a buried state of a pipe by the burying method of the present invention. In the figure, 1 is a buried groove and 2 is a pipe.

てその殆んどを占めるようになっている。In this embodiment, as the resin foam block, a pair of resin foam blocks 3a and 3b having a semicircular groove 30 as shown in FIG. The flat resin foam block 3c to be arranged is used. When the resin foam blocks 3a, 3b, 3c are arranged in the buried groove 1, most of the resin foam blocks 3a, 3b, 3c are occupy except a part of the groove 1 on the surface layer side.
次に、これらによる埋設方法を説明すると、埋設溝１内

のを防止する上で有利である。Explaining the embedding method using these, the resin foam block 3a is fitted into the embedding groove 1 with the groove 30 facing upward, and the pipe 2 is arranged in the groove 30.
The resin foam block 3b is placed, and the resin foam block 3c is further arranged thereon. Then, the sand 6 (60 is a gravel layer, 61 is a sand layer) is backfilled on the resin foam block 3c, that is, on a part of the surface layer side. It should be noted that this earth and sand is advantageous in preventing the resin foam block from being melted out by heat during concrete pouring.

めるようになっている。FIG. 3 shows another embodiment. As the resin foam block, a pair of upper and lower resin foam blocks 3a and 3b similar to those shown in FIG. 1 and resin foam blocks arranged on both sides thereof. 3d and 3e are used. These resin foam blocks 3a, 3b, 3d, 3e also occupy most of the grooves 1 when they are arranged in the buried groove 1, except for a part of the groove 1 on the surface layer side.

が埋め戻され、その上に敷石８が敷設されている。Further, FIG. 4 is an example of embedding a distance section pipe (sewer pipe, etc.). In this case, first, a flat resin foam block 6f is laid on the bottom of the embedding groove 1 and is laid on it. In addition to arranging the pipe 2 ', a flat plate-shaped resin foam block 3g, 3h having an upper end surface flush with the upper surface of the pipe is arranged on the pipe side. The foam block 3i is arranged. These resin foam blocks 3f, 3g, 3h and 3i also occupy most of the buried groove 1 except for a part on the surface layer side, as shown in the figure. Note that earth and sand 6'on the resin foam block 3i.
Is backfilled and paving stone 8 is laid on it.
以上述べた本発明の配管の埋設方法によれば、埋設溝の
殆んどを占めるように、樹脂発泡体ブロックを周囲に配
して配管を埋設するため、次のような効果が得られる。According to the pipe burying method of the present invention described above, the resin foam block is arranged around the pipe so as to occupy most of the burying groove, and the pipe is buried, so that the following effects can be obtained.
埋戻し用の良質の土砂の使用量が表層側の一部だけ
でよいため極く小量で済み、配管埋設工事を低コストに
行うことができる。Since only a part of the surface layer of good quality earth and sand for backfilling needs to be used, only a very small amount is required, and pipe burying work can be performed at low cost.
材質が均一で、強度も十分な発泡スチロール等の樹
脂発泡体が埋設溝の殆んどを占めつつ配管を囲むため、
地盤沈下等によって配管に負荷応力が発生したり、地震
時の地盤ひずみが配管に直接伝播することが少なく、内
容物の漏洩等を効果的に抑えることができる。Since the resin foam such as Styrofoam, which is made of uniform material and has sufficient strength, occupies most of the buried groove and surrounds the pipe,
Load stress is not generated in the pipe due to ground subsidence, etc., and ground strain at the time of an earthquake is rarely directly transmitted to the pipe, and leakage of contents can be effectively suppressed.
樹脂発泡体ブロック中に配管を敷設し、しかもそれ
が埋設溝の殆んどを占めているため、掘り上げて配管を
露出させることが極めて容易である。Since the pipe is laid in the resin foam block, and it occupies most of the buried groove, it is extremely easy to dig up and expose the pipe.
配管の点検や補修のための掘上げ作業に際しても重
機（バックホー、トラック）を用いる必要がまったくな
く、このため配管を傷めることはない。There is no need to use heavy equipment (backhoe, truck) at the time of excavation work for inspection and repair of the piping, and therefore the piping is not damaged.
