Description

  The present invention relates to a method for building a temporary road using a sandbag, and more particularly, to build a temporary road using a sandbag that builds a temporary road by stacking sandbags on a field or a field lower than the road so as to be approximately the same height as the road. It is about the method.

  As shown in FIG. 7, a plurality of floor boards 51 whose upper and lower surfaces are formed into right-angled isosceles triangles are connected via a hinge device 52 so as to be detachable and rotatable in the vertical direction. There is a temporary road 54 configured by supporting the top with a sandbag 53 (see, for example, Patent Document 1).

In the temporary road 54, the floor boards 51 are connected to each other so as to be pivotable in the vertical direction via the hinge device 52. Therefore, when the ground sinks, one floor board 51 is connected via the hinge device 52. Since it is tilted by rotating in the vertical direction with respect to the other floor board 51, it is possible to prevent a step between the floor boards 51.
Japanese Patent Laid-Open No. 10-121405

  However, when the above-described temporary road 54 is constructed in a place where unevenness is formed by, for example, vineyards and valleys, a portion corresponding to the apex of each floor board 51 can be stably supported by a soil pad 53. There is a problem that it is not possible.

  Further, when the sandbag 53 of the sandbag 53 is torn and the filling material flows out, not only the floor board 51 can be stably supported but also the soil at the place where the temporary road 54 is built may be adversely affected.

  The present invention has been made in view of such a problem, and can be used to build a temporary road even in an uneven area, and can be used to build a temporary road without affecting the soil where the temporary road is built. The purpose is to provide a method for building a temporary road.

The temporary road building method using a sandbag according to claim 1 is a temporary road building method using a sandbag for building a temporary road using a sandbag in a place lower than the road, and the road for building the temporary road. After laying a sheet larger than the temporary road construction planned site on the lower temporary road construction planned site, repeatedly performing the laying work of laying sandbags on the sheet within the range of the temporary road building planned site stacking the sandbags so as to be substantially equal to the height and the road, the periphery of the sheet so as to cover the side surfaces of the entire stacked sandbags a bent upward, further, the Rukoto folded so as to cover the upper surface of the uppermost sandbags It is a feature.

  The temporary road building method using the sandbag according to claim 2 is the temporary road building method using the sandbag according to claim 1, wherein the temporary road building planned land is provided with an uneven surface. The present invention is characterized in that, after a sandbag is laid out in the recesses of the road construction planned site and a flat surface is formed by the sandbags laid in the upper surface of the convex portion and the recesses, the sandbags are laid out on the plane.

  The temporary road building method using the sandbag according to claim 3 is the temporary road building method using the sandbag according to claim 1 or 2, wherein the filling material of the sandbag is sand.

  According to the method for building a temporary road using sandbags according to claim 1, the temporary road is built by stacking the sandbags, so that the banking is not mixed with the soil where the temporary road was built. A temporary road can be constructed, and the construction of the temporary road can prevent the soil from being affected. In addition, even if the dirt bag breaks and the filling material flows out, the piled sandbags are cut off from the soil by the sheets, so that it is possible to reliably prevent the embankment from being mixed with the soil. it can. Therefore, it is possible to build a temporary road even in places where water is stretched such as rice fields and streams.

  According to the method for building a temporary road using sandbags according to claim 2, for example, when a temporary road is built in a place where unevenness is formed by reeds and valleys, such as in a field, the temporary road is not destroyed. A road can be built. In addition, when removing a temporary road built by the method of building a temporary road using sandbags, it is not necessary to dig up the embankment, so the temporary road can be easily removed without destroying the fence. .

  According to the temporary road building method using the sandbag according to claim 3, for example, in the removal work of the sandbag of the temporary road built in the paddy field, the filling material has accidentally flowed out of the sandbag into the paddy field. However, there is an advantage that it does not affect the water quality of the paddy field or rice.

  Hereinafter, the temporary road construction method using the sandbag which concerns on embodiment of this invention is demonstrated based on drawing. FIG. 1 shows the relationship between a temporary road construction planned site 1, a road 2, a road 3, and a planned building site 4 for building a house, etc., for constructing a temporary road by a temporary road construction method using a sandbag. The temporary road construction planned site 1 located between the road 2 and the planned building site 4 is a field having a step h with the road 2, the road 3, and the planned building site 4 in the present embodiment. A method for constructing a temporary road on the temporary road construction planned site 1 so as to be approximately the same height as the road 2 and the planned building site 4 will be described below.

  An uneven surface is formed by a ridge (convex portion) 5 and a valley portion (concave portion) 6 on the temporary road construction planned site 1 which is this field. Thus, a sandbag 7 is prepared to be laid out on the temporary road construction planned site 1 on which the uneven surface is formed. As shown in FIG. 2, the sandbag 7 is formed by putting a predetermined amount of unfilled filling material into the sandbag 8 and tying it with a string 9. Here, the filling material to be put into the sandbag 8 is not particularly limited as long as it is similar to soil or the like, and for example, crusheran, crushed stone, firewood, sandy soil or the like can be used. In addition, by using the same sand as the soil of the temporary road construction site 1 as the filling material, even if the filling material flows out from the sandbag 7, it will affect the soil of the temporary road construction site 1 Can be prevented. Further, by adjusting the amount of filling material to be put in the sandbag 8, it is possible to adjust the height of the sandbag 7 when the sandbag 7 is arranged.

  In this way, as many sandbags 7 as necessary for constructing the temporary road are prepared, and the sheet 10 is first laid so as to cover the entire surface of the temporary road construction planned site 1. This sheet 10 is for cutting off the soil of the temporary road construction planned site 1 and the sandbag 7 and has water repellency. In addition, as will be described later, the peripheral edge of the sheet 10 is bent upward so as to cover the entire side surface of the sandbag 7 stacked on the sheet 10 in a plurality of layers. Those formed so as to be wider than 1 are used.

  Subsequently, a sandbag 7 is laid on the sheet 10 within the range of the temporary road construction planned site 1. Here, in the field which is the temporary road construction planned site 1, an uneven surface is formed by the ridges 5 and the valleys 6 as described above. Therefore, here, as shown in FIG. 3, the first sandbag 7 is laid on the sheet 10 of the valley 6 between the ridges 5. At this time, the arranged sandbags 7 are rolled by the plate runner about three times from above so that a flat surface is formed by the first sandbag 7 placed on the upper surface of the trough 5 and the valley 6.

  In this way, a first layer of sandbags 7 is laid on the valley 6 and a plane is formed by the upper surface of the ridge 5 and the sandbag 7 laid on the valley 6, and then, as shown in FIG. Laying the second layer of sandbags 7 in a balanced manner is performed. After the second layer of sandbags 7 has been laid out, a packing material 11 such as a crusher orchid is spread out in the gap between the sandbags 7. After the completion of the operation of squeezing the packing material 11, the second layer of sandbag 7 is rolled with a plate runner, taking care not to damage the sandbag 7. At this time, the rolling operation is performed while performing level control so that the heights of the sandbags 7 arranged are equal.

  Thereafter, the work from the laying work of the second layer of sandbags 7 to the rolling work is repeatedly performed, and the sandbags 7 are stacked so that the height is substantially equal to the ground of the road 2 or the planned construction site 4. FIG. 5 is a view showing the sandbags 7 stacked in this manner. As shown in the figure, sandbags 7 are stacked so as to have a height substantially equal to the bottom surface of the road 2 and the planned construction site 4. In addition, when the sandbags 7 are stacked, if the end portion protrudes to the side, adjustment is performed using the adjustment sandbag 12 in which the amount of the filling material is halved, and the sandbags 7 of each layer are stacked. Is performed in a staggered arrangement using the adjustment sandbag 12 in order to efficiently distribute the load.

  After completion of the stacking of the sandbags 7 in this way, before the first sandbag 7 is laid out, the upper side of the entire sandbag 7 on which the sheets 10 laid on the temporary road construction planned site 1 are stacked is covered. Bend it. Finally, the sheet 10 folded upward is further folded to fix the peripheral edge of the sheet 10 and the iron plate 13 is laid out so as to cover the upper surface of the uppermost sandbag 7 to complete the operation. A rubber sheet may be laid out in place of the iron plate 13.

  FIG. 6 shows a cross-sectional shape of the temporary road 14 built by the above-described work. After filling the valley 6 between the ridges 5 and 5, a first layer of sandbags 7 is laid and a plane is formed by the upper surface of the ridge 5 and the first level of sandbags 7, and then the second and subsequent layers of soilbags After 7 is stacked up to approximately the same height as road 2, road 3, and planned construction site 4, an iron plate 13 is disposed on the upper surface thereof. A vehicle or the like for transporting building materials from the road 2 or the road 3 can enter the planned construction site 4 through the temporary road 14 constructed in this way. In addition, by placing the first layer of sandbags 7 in the valley 6 between the cages 5 and 5, the piles of the second and subsequent soilbags 7 are stacked, so that the load concentrates on the cage 5 and destroys the cage 5. Can be prevented. Further, the temporary road 14 formed by stacking the sandbags 7 is covered with the sheet 10 at the bottom and side surfaces thereof, and the top surface of the top sandbag 7 is covered with the iron plate 13. Therefore, even if the soil bag 8 is damaged and the filling material flows out to the outside, it is possible to prevent the filling material from being mixed with the soil in the field and adversely affecting the soil. Moreover, deterioration of the sandbag 8 due to ultraviolet rays or the like can be prevented.

  The temporary road 14 is removed by first removing the iron plate 13 on the upper surface of the temporary road 14 and then removing the piles 7 one after another. Since the sandbag 7 has the string 9 as described above, it is possible to hook the string 9 on the hook of the crane and remove the plurality of sandbags 7 together. Then, when all the piles 7 are removed, the filling material 11 sprinkled into the gap between the sandbags 7 and 7 is scattered on the sheet 10, so that the filling material 11 flows out of the sheet 10 and flows into the field. The sheet 10 is removed while being careful not to mix with the soil. Further, the removed sandbag 7 and the sheet 10 can be reused after removal, and the filling material can be reused even when the sandbag 8 is deteriorated.

  The place where the temporary road 14 is constructed by the method for constructing the temporary road using the sandbag described above is not limited to the field, and may be, for example, a rice field or a stream. Can be built on site. Moreover, since the bottom and side surfaces of the temporary road 14 are covered with the sheet 10, the temporary road 14 can be built even in a field where water is stretched. In addition, when constructing in a creek, it is possible to construct the temporary road 14 while securing a water channel by laying a plurality of sheets 10 at a predetermined interval and stacking sandbags 7. Moreover, in this Embodiment, although the case where the temporary road 14 was built using the sandbag 7 in the field between the road 2 and the construction planned land 4 with the same ground height was demonstrated, for example, a construction planned site When 4 is higher than the road 2, it is natural that the sloped temporary road 14 can be built by increasing the number of sandbags 7 stacked on the planned construction site 4 side than the road 2 side. It is.

  This is applicable when a temporary road is constructed in a place such as a rice field, a field, or a stream that is lower than the road.
