Description
【0001】[0001]
本考案は、電話線等の管路敷設工事において掘削した溝に投入される砂を平ら に均すための砂の敷均し器に関する。 The present invention relates to a sand leveling device for leveling sand that is put into a trench excavated in a pipeline laying work such as a telephone line.
【0002】[0002]
従来の電話線等の管路を地下に敷設する工事においては、掘削した溝に管路を 付設して埋戻しの砂を投入した後、作業者が路上から長柄のジョレンやスコップ 等で管の周辺の砂をほぼ平らに均す作業を行っている。 In the conventional construction for laying pipelines such as telephone lines underground, after installing pipelines in excavated trenches and inserting backfilled sand, workers use pipes with a long handle, such as Jollen or a scoop, to remove pipes from the street. We are working on leveling the sand around it.
【0003】[0003]
上記した従来の掘削溝の敷砂、管路付設後の管上の周辺砂の敷均し作業は、ジ ョレン等による人力作業であるため、溝幅35〜60cmで100〜160cm の深さにある砂を地上から均すことは大変手間がかかって煩わしく、作業性が悪 いものであった。しかして、かかる敷均し作業を簡易に行う新規な用具の開発が 要望されていた。 The above-mentioned conventional sand laying of excavation trenches and laying of the surrounding sand on the pipe after the pipeline is installed are manual labor by Joren, etc., so the depth of 100 to 160 cm at a groove width of 35 to 60 cm. Leveling a piece of sand from the ground was very time-consuming, cumbersome, and poor in workability. Therefore, there has been a demand for the development of a new tool that can easily perform such a leveling work.
【0004】 本考案の目的は、掘削溝の敷砂、管路付設後の管の周辺砂の敷均し作業の労力 の軽減と、作業性の向上に寄与する砂の敷均し器を提供することにある。An object of the present invention is to provide a sand leveling device that contributes to reduction of labor for leveling sand for excavation trenches, sand leveling around pipes after installation of pipelines, and improvement of workability. To do.

The horizontal tube is connected and fixed to the tip of the middle cylinder.
【0007】[0007]
横管の小孔から加圧空気を噴出させて盛り上がった砂を吹き飛ばしつつ、作業 者が柄本体を手前に引く動作を繰り返すことにより、掘削溝の敷砂、管路付設後 の管の周辺砂を均し板でほぼ平らにする敷均し作業を行う。柄本体の長さは、中 筒を出し入れすることにより掘削溝の深さに合わせて容易に調節することができ る。 Pressurized air is blown out from the small holes in the horizontal pipe to blow away the rising sand, while the worker repeatedly pulls the handle body toward you, which results in sand laying in the excavation trench and sand around the pipe after the pipe is installed. Perform leveling work by making the leveling plate almost flat with a leveling plate. The length of the handle body can be easily adjusted according to the depth of the excavation groove by inserting and removing the middle cylinder.

【0010】 図1において、砂の敷均し器1の中空状で長い柄本体2には、加圧空気を供給 する供給口4を形成した短い接続管3を一体に設け、該接続管3に切替コック5 を取り付ける。6は該切替コック5に接続され、別途コンプレッサーpから圧力 7kg/cm2程度の圧縮空気を送るためのホースである。7は柄本体2の上端に 設けた棒状のハンドルである。In FIG. 1, a short long connecting pipe 3 having a supply port 4 for supplying pressurized air is integrally provided on a hollow and long handle main body 2 of a sand leveling device 1. Attach the switching cock 5 to. Reference numeral 6 is a hose which is connected to the switching cock 5 and separately sends compressed air having a pressure of about 7 kg / cm 2 from the compressor p. A bar-shaped handle 7 is provided on the upper end of the handle body 2.
【0011】 上記柄本体2は、外筒8とこれに移動調節可能に遊嵌して締付金具10で固定 される中筒20とからなる。その締付金具10は外筒8の端縁8aに接するパッ キン11と座金12と袋ナット13を備え、外筒8に袋ナット13を螺合固定し て気密を維持する構成とされている(図5)。また、中筒20には筒端部21に 連通させた縦溝22を長手方向に形成し、該縦溝22に連続させて半径方向に適 宜数の係止溝23を設ける。図1に示すように、その係止溝23を前記外筒8に 設けたピン8bに係合することにより、中筒20が外筒8から抜け落ちないよう に構成している。The handle main body 2 includes an outer cylinder 8 and a middle cylinder 20 that is loosely fitted in the outer cylinder 8 so as to be movable and fixed, and is fixed by a tightening fitting 10. The tightening metal fitting 10 includes a packing 11, a washer 12, and a cap nut 13 that are in contact with the end edge 8a of the outer cylinder 8. The cap nut 13 is screwed and fixed to the outer cylinder 8 to maintain airtightness. (Fig. 5). Further, a vertical groove 22 communicating with the tube end portion 21 is formed in the middle cylinder 20 in the longitudinal direction, and an appropriate number of locking grooves 23 are provided in the radial direction so as to be continuous with the vertical groove 22. As shown in FIG. 1, the engagement groove 23 is engaged with the pin 8b provided on the outer cylinder 8 so that the middle cylinder 20 does not fall off from the outer cylinder 8.
【0012】 上記中筒20の先端には、図3に示すように加圧空気を噴き出す複数個の小孔 26を軸方向に設けた横管25が直交状に連結固定されている。その小孔26は 直径5〜8mmの大きさで、中筒20の軸心に対して前方向に約30°の角度に 配置されている。また、小孔26側には図2、3に示すように、櫛歯状に形成し た薄板材料からなる均し板27を横管25に沿うように設ける。なお、上記供給 口4から小孔26までの間は、加圧空気を導くように設けるものとする。As shown in FIG. 3, a horizontal pipe 25 having a plurality of small holes 26 for ejecting pressurized air in the axial direction is fixedly connected to the tip of the middle cylinder 20 in an orthogonal manner. The small hole 26 has a diameter of 5 to 8 mm and is arranged at an angle of about 30 ° in the front direction with respect to the axis of the middle cylinder 20. Further, as shown in FIGS. 2 and 3, a leveling plate 27 made of a comb-shaped thin plate material is provided along the horizontal pipe 25 on the side of the small hole 26. The space from the supply port 4 to the small hole 26 is provided so as to guide pressurized air.
【0013】 次に、かかる構成になる砂の敷均し器1による敷均し作業につき、図6に基い て説明する。 掘削した溝aに管bを付設して埋戻しの砂sを投入した後、作業者が均し板2 7を盛り上がった砂sの上に乗せて柄本体2を手前に引く動作を行う。コンプレ ッサーpから供給される加圧空気が小孔26から噴出されて、盛り上がった砂s は周囲に吹き飛ばされ、同時に、均し板27でかきならされて周囲に広がる。か かる敷均し作業を適宜繰り返して、管bの周辺砂sを徐々に平らに仕上げる。そ して、かかる敷均し作業を終えた後は、転圧機により砂sをつき固める公知の作 業が行われる。Next, the leveling work by the sand leveling device 1 having such a configuration will be described with reference to FIG. After the pipe b is attached to the excavated groove a and the backfilled sand s is put therein, an operator puts the leveling plate 27 on the raised sand s and pulls the handle main body 2 forward. Pressurized air supplied from the compressor p is ejected from the small holes 26, and the raised sand s is blown to the surroundings, and at the same time, the sand s is scratched by the leveling plate 27 and spreads to the surroundings. The sanding operation is repeated as appropriate to gradually finish the sand s around the pipe b. After finishing the leveling work, a publicly known operation of solidifying sand s by a compactor is performed.
