In particular, the step 12 is provided with a grating 100, the grating 100 is formed in an arc shape so that it can be naturally connected as a band. At this time, the curvature inner surface of the step 12 is formed to have a curvature C, as in 2b. Here, "C" denotes a curvature, but means a curved portion of the inner surface of the actual step 12.

At this time, the stepped portion 12 has both ends curvature toward the upper side of the trapezoid, thereby forming an arc shape having a predetermined radius of curvature when connecting several bodies 10 as shown in FIG.

This step 12 is to be installed when there is a height difference of the buried position or to place the height difference when laying the drainage pipe, the height is determined according to such a height difference.

In addition, at least one upper catchment hole 13 is formed on the upper surface of the body 10 so that the channel 11 and the stepped portion 12 communicate with each other. The upper catch port 13 is formed in the step 12 to guide the rainwater through the upper portion of the body 10 to be collected into the water channel 11.

The upper catchment port 13 forms one or more at regular intervals according to the length of the body 10. In addition, the upper catchment 13 may be manufactured and used in a curved form according to the shape of the channel 11.

In addition, the side surface catch port 14 is formed on the side of the body (10). The side catch port 14 is formed to communicate with the channel 11, the outer end is formed so as not to leave the side of the body (10). That is, the body 10 is to be buried in the side, the side catch port 14 is also formed to be embedded in the ground with the body 10.

Finally, the body 10 is formed with a convex portion (15a) and the recessed portion (15b) to be used in connection with other drainage pipe. These convex portions 15a and concave portions 15b are formed on the pair of slopes 10a, respectively.

The convex portions 15a and the concave portions 15b are opposite to each other, and the convex portions 15a protrude outward from the body 10, and conversely, the concave portions 15b are recessed into the body 10.

The convex portion 15a and the concave portion 15b formed as described above are concave and convex with each other when connecting two adjacent bodies 10. At this time, these coupling parts are finished using mortar or the like.

On the other hand, the drain pipe according to the present invention has been described as an example of the three-dimensional block of the trapezoidal planar shape is not limited thereto. As another embodiment, there may be difficulty in manufacturing, but the base of the trapezoid may be manufactured in an arc shape.

The grating 100 used in the present invention is manufactured in a circular shape having an overall shape is a fan shape, preferably the outer curvature c of the grating 100 has the same curvature C as the step 12. By connecting them in a snap-fit manner to form a smooth arc shape, the aesthetics can be improved.

In addition, although the grating 100 is described as having a fan shape, the grating 100 may have a curvature c only on the outside of the grating 100 and may be formed in a straight line without forming a curvature inside.

The grating 100 includes a plurality of grating structures 110 formed therethrough from above; A plurality of side collecting holes 120 formed to communicate with the collecting lattice structure 110 from both sides in a longitudinal direction; A pair of mounting rings 130 formed at one side of the widthwise edge; And a snap fit 140 formed at an edge in the width direction of the other side so as to be in a position corresponding to each of the mounting rings 130 and connected to another grating structure.

The collecting grid structure 110 is formed to penetrate from the top to the bottom of the grating 100. In particular, the grating structure 110 is composed of a rectangular grid 111 having a predetermined size and an "X" type grating 112 formed inside these square grids 111. In particular, the "X" type grid 112 connects the corner portions of the square lattice 111, thereby partitioning the inner size of the square lattice 111 into four.

In particular, it is preferable to form the anti-slip projections 111a on the corners of the square lattice 111 so as to prevent injuries due to slipping even if rain or foreign snow falls. The anti-slip protrusion 111a may be formed on the “X” type grid 112 as well as the square grid 111.

Side collection holes 120 are formed on both sides of the grating 100. Typically, the grating 100 is manufactured to have a rectangular parallelepiped shape having a length longer than the width, and the side catchment holes 120 are formed at both sides of the grating 100 in the longitudinal direction.

The side catchment holes 120 are configured to communicate with the lattice structure 110, such that rainwater collected through the side catchment holes 120 may be collected into the channel 11 of the drainage pipe through the lattice structure 110. It is desirable to be able to configure.

The mounting ring 130 is formed at one side edge portion of the grating 100 in the width direction. In particular, the mounting ring 130 forms a pair on the grating 100 in order to firmly bond with the neighboring grating 100.

The grating 100 is preferably configured such that the cantilever-type locking ring 142 of the snap-fit 140, which will be described later, is cut by cutting a portion of the side on which the mounting ring 130 is formed.

It is configured to include. In addition, the fastener 150 is manufactured in a form in which at least two pairs face each other in the grating 100, but it is also possible to increase the number according to the length of the grating 100.

The partition wall part 150b is formed to accommodate one end of the fixing bar 150a therein. The partition portion 150b shows an example manufactured in a rectangular shape in the drawing, but it is also possible to manufacture a variety of forms that can secure a fixed force such as a circle or a triangle.

In particular, the fixing protrusion 153 is formed on one surface of the partition wall portion 150b, preferably, the surface facing each other. It is used to fix the fixing bar 150a by being inserted into the fixing hole 152 which will be described later.

In addition, the partition wall portion 150b is formed in the grating 100 so as to be located at both sides of the upper catchment port 13 of the drainage pipe, so that each fixing bar 150a is fitted to the upper catchment port so that the partition can be mounted on the drainage pipe. desirable.

Fixing bar (150a) is a member made of a rod shape, it is preferable to manufacture in a hollow hollow form. This is to make it easy to attach the fixing bar (150a) to the partition portion (150b) to make the elastic deformation to the hollow portion. Of course, the fixing bar 150a may further comprise a plurality of partition walls (not shown) to secure its rigidity when manufactured in a hollow.

The fixing bar 150a has a locking jaw 151 formed at one end thereof, and a fixing hole 152 is formed at the other end side thereof to allow the fixing protrusion 153 to be fitted thereto. In particular, the fixing hole 152 is formed in the cut piece 154 in which the side wall portion of the fixing bar 150a is partially cut, so that the elastic deformation of the cut piece 154 is fixed even if the fixing hole 152 is fixed to the fixing protrusion 153. Using the fixed bar 150a is preferably formed to have a certain degree of play.
