  In the stair block disclosed in Patent Document 1, the slope is dug down before the stair block is provided, the back-ground crushed stone with a predetermined gradient is provided, and the stair block is continuously provided thereon. However, in terms of revetments such as revetment where the water level changes significantly, there are many cases in which the surface is always wet and the ground is very soft, so that there is a problem that the foundation construction by the back crushed stone is complicated and troublesome.

  Moreover, in the stair block in patent document 2, an assembly stair block with a pre-stabilization plate | board with which a tread surface part, a kick-up part, and a side wall part were connected and assembled with the connection screw nail with respect to the slope is hit | damaged by a non-slip pile. However, the slope is always wet, and when it rains, water often blows out from the inside and the slope collapses.Therefore, it is very difficult to attach the stair block to the slope with only non-slip piles. There is a problem that becomes stable.

  The present invention was devised in view of the above points, and a method for constructing a stair block on a slope and an integrated stair on the slope capable of attaching the stair block to the slope via a filter cloth. The purpose is to provide blocks.

  In order to achieve the above object, a method for constructing a stair block on a slope according to the present invention includes a step of fixing a stair block on a filter cloth having water permeability at regular intervals, and the filter cloth on the slope And a step of engaging the stair block on the filter cloth with the anchor pin with respect to the slope.

  Here, by attaching a filter cloth that allows only water to the slope with an anchor pin, it is possible to prevent sediment from flowing out due to rainfall. In addition, the plant is vegetated from the slope through the filter cloth mesh so that the filter cloth and the slope are integrated, and a solid stair block can be constructed.

  In order to achieve the above object, the stair block on the slope according to the present invention is fixed to the filter cloth having water permeability laid on the slope and at regular intervals on the filter cloth. Equipped with a stair block.

  Here, the filter cloth is woven so that only water can pass through synthetic fibers such as polyethylene and polyester, which have high tensile strength and excellent durability, so that only the water does not pass through it. By adhering with an adhesive, the stair block can be easily constructed by attaching the filter cloth to the slope with an anchor pin.

  In addition, by installing a slope protection block between the stair block, the stair block can be stably constructed without slipping on the slope, and a vegetation opening is provided in the slope protection block to provide a filter. The cross, the slope protection block and the stair block can be constructed integrally with the slope.

  In the present invention, before installation, a stair block is attached to the filter cloth by an adhesive at a factory or the like, and then transported to the site, lifted by a crane, placed on a slope, and attached by an anchor pin within a short time. It becomes possible to construct easily.

  In addition, the filter cloth does not cause sediment to flow out even in rain, does not cause the slope to lose shape, and the vegetation from the slope makes the filter cloth, the slope protection block, and the staircase block integral with the slope. Will be installed.

FIG. 1 is an explanatory side view showing an example of a method for constructing a stair block on a slope to which the present invention is applied, and FIG. 2 is a plan view of FIG.
As shown here, stair blocks 2, 2,... Are placed at predetermined intervals by a durable epoxy resin adhesive on a filter cloth 1 having an area larger than the total length and width of the stair in advance at a factory or the like. It sticks.

  The slope protecting block 3 is spread with an adhesive between the stair block 2 and around the stair block. The slope protecting block 3 is provided with vegetation holes 4 at the center and on each side, and these vegetation holes 4 are exposed on the filter cloth 1.

  Further, an anchor pin insertion hole 5 is provided in the stair block 2, and the stair block 2 and the filter cloth 1 are connected to the slope 7 by inserting the anchor pin 6 into the slope 7 through the anchor pin insertion hole 5. Install on top.

  Therefore, it is possible to easily install the stairs on the slope by carrying it to the site by a truck, etc., lifting the filter cloth with the stair block and slope protection block fixed on the crane and lowering it to the predetermined slope. It becomes.

  Moreover, as shown in FIG. 3, the slope 7 and the filter cloth 1 are integrated by the plant 8 growing through the mesh of the filter cloth 1. Further, when the plant 8 grows from the vegetation hole 4 of the vegetation hole 4 of the slope protection block 3 through the mesh of the filter cloth 1, the slope protection block 3 and the filter cloth 1 on the slope 7 The stair block 2 surrounded by the surface protection block 3 is further stabilized.

Next, an example of the integrated stair block on the slope to which the present invention is applied is shown.
The integrated stair block 9 shown here is fixed to the filter cloth 1 and the filter cloth 1 with an adhesive at regular intervals, as shown in an example of a stair block construction method on the slope to which the present invention is applied. And a slope protecting block 3 fixed between and around the stair block 2 with an adhesive.

  Therefore, the filter cloth 1 is woven so that a network through which only water passes is formed by synthetic fibers such as polyethylene and polyester having high tensile strength and high durability.

  As shown in FIG. 4, the stair block 2 includes a bottom surface 10, a rising surface 11, and a footrest surface 12 as a secondary concrete product, and has four anchor pin insertion holes 5 perpendicular to the footrest surface 12. It is to be drilled. Further, the footrest surface 12 is made horizontal by setting the contrast between the bottom surface 10 and the rising surface 11 to 1.5: 1 or 2: 1 according to the inclination angle of the slope.

  Next, as shown in FIG. 5, the slope protecting block 3 is a concrete block body having four sides that are square, and a circular vegetation hole 4 is formed in the center thereof. A semicircular vegetation groove 13 is formed at the center of the side. Therefore, when each slope protection block 3 is laid, the vegetation hole 4 is formed between each slope protection block 3 and between the stair block 2.

  Further, as shown in FIG. 4, the anchor pin 6 is formed in a bifurcated shape so as to straddle the two anchor pin insertion holes 5, and the anchor pin 6 has four anchor pin insertion holes. The stair block 2 is engaged with the slope by piercing the slope 5 vertically by the two anchor pins 6.

  In the present invention having the above configuration, since the stair block and the slope protection block are fixed to the filter cloth, the individual stair block and the slope protection block are not attached to the slope, and the filter By laying the cross against the slope, it can be easily constructed in a short time.

  Also, the filter cloth and the slope protection block are integrally and firmly engaged by vegetation from the slope. Furthermore, the filter cloth allows only water to pass through, preventing the sediment from flowing out and preventing the sinking or shifting of the stair block.

  The stair block engagement mechanism with respect to the slope is not necessarily an anchor pin, and any mechanism can be used as long as it can be easily engaged.

  Further, the stair block or the slope protection block is not necessarily fixed to the filter cloth by an adhesive, and any material may be used as long as it is durable and can be firmly fixed. .
