【考案の属する技術分野】[Technical field to which the invention belongs]

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]

【従来の技術】[Prior art]

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]

【考案が解決しようとする課題】[Problems to be solved by the device]

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.

【考案の作用及び効果】[Actions and effects of the invention]

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.

【考案の実施の形態】[Embodiment of the invention]

以下に、本考案の実施の形態例を図面に基づいて説明する。図１は一部を破断した砂の敷均し器の側面図、図２は中筒の側面図、図３は図２のＡ矢視図、図４は図３のＢ−Ｂ線断面図、図５は締付金具部分の断面図、図６は砂の敷均し器の使用状態を示す説明図である。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of a partially broken sand leveler, FIG. 2 is a side view of a middle cylinder, FIG. 3 is a view taken in the direction of arrow A of FIG. 2, and FIG. 4 is a sectional view taken along line BB of FIG. 5 is a cross-sectional view of the tightening fitting portion, and FIG. 6 is an explanatory view showing a usage state of the sand leveling device.

【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２７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.

【００１４】しかして、この砂の敷均し器は掘削溝の敷砂、管路付設後の管の周辺砂の敷均し作業を容易とし、作業性の向上に役立つものである。However, this sand leveler facilitates leveling work of the sand in the excavation trench and the sand around the pipe after the pipe is installed, and is useful for improving workability.
