Abstract

The waterway net for covering the sloped earth surface, prevents the loss of the earth and sand caused by rain falls, and drains rain water on the slope surface efficiently. The waterway net having longitudinal lines and latitudinal lines, is moulded integrally, in a way a longitudinal line having a longitudinal grooves on the surface and a latitudinal line having a latitudinal groove on the surface. The latitudinal line is slantedly arranged for smoothly draining rain water, and is arranged to form a rhomb-type lattice. The reinforcing lines are positioned between the latitudinal lines.

The present invention relates to a sloped protective synthetic resin channel network that is covered and fixed to the slope to prevent the loss of soil by rainwater.

In the construction of apartment complexes, roads or rivers located in hilly areas, site construction that makes the ground level is essential. The slopes newly formed by the cut and fill work accompanying these site constructions become unstable, so that the surface surface is easily collapsed in the natural environment such as rainwater. In order to prevent the earth and sand from collapsing due to rainwater, it is common that slope protection work is performed on newly formed slopes. Various types of slope protection are used for these slope protection. One of them is a net.

As shown in FIG. 1, the netting method used in the slope protection is excavated with an upper pit 2 on the upper side of the slope 1, a lower pit 3 on the lower side, and an upper portion of the mesh 4 as shown in FIG. After fixing with the fixing pile (5) inside the upper pit (2) and backfilled with soil, and firmly supported, spread the net (4) on the slope surface (1) while sloped with a fixed nail (6) at appropriate intervals (1) Fixed to the bottom of the net (4) with a fixed pile (5) inside the lower pit (3) and then backfilled with soil, and firmly supported, to prevent the soil from collapse and flow down the slope (1) to be.

As shown in FIG. 2, the conventional net 4 used in such a netting method has a structure in which the vertical lines 4a and the horizontal lines 4b are woven so as to cross each other at a predetermined interval.

Since the conventional net 4 is first intersected in a structure in which the vertical wire 4a and the horizontal wire 4b are simply interwoven, local breakage of the net 4 spreads due to the weakening of the soil holding force of the entire net 4. Was flawed; Second, since the mesh 4 itself could not perform the role of draining the rainwater falling on the slope 1, there was a defect in that the rain and earth could not be efficiently suppressed from flowing down the slope.

An object of the present invention is to provide a synthetic resin channel for slope protection, where local damage is limited to only that portion, and the function of the entire net is preserved. In addition to rainwater, the present invention provides a synthetic resin channel for slope protection that effectively suppresses downflow.

Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail as follows.

As shown in FIG. 3 and FIG. 4, the present invention is a synthetic resin material which integrally forms a mesh consisting of vertical lines 10A and horizontal lines 20A, wherein the vertical channel 10A is formed on the vertical line 10A. It is a basic feature in the technical configuration that the vertical line 10 is formed to be formed in the part.

Since the mesh of the present invention configured as described above has a structure that is integrally molded as a synthetic resin material, the wires corresponding to the portion are integrally connected through the periphery thereof, even if there is a local breakage. Function has the effect of being preserved as it is; Second, since rainwater falling on the slope on which the mesh of the present invention is installed flows down through the vertical channel 11, it has an effect of preventing the soil on the slope from being lost with rainwater.

On the other hand, in the first embodiment of the present invention shown in Figs. 5 to 10, in addition to the above-described basic configuration, the horizontal row 20A is provided with a horizontal row groove 21 having a horizontal channel groove 21 in its surface portion. Are formed, and the reinforcing lines 30 are integrally formed between the row and row lines 20, and a pair of connecting bands 40 are integrally formed on both sides.

Here, the row row line 20 serves to allow rainwater falling on the slope to be pulled down in the row row groove 11 by the road row groove 21, and the reinforcement row 30 is the entire net. Increasing the strength of the connection belt 40 serves to help the network of the present invention is connected to each other overlapping. As shown in FIG. 9, the connection strip 40 may have a pile hole 41 to which a fixed pile is to be embedded at predetermined intervals.

In addition, the horizontal row line 20 may be formed horizontally, but as shown in FIG. 8, it is preferable that the horizontal row line 20 is inclined so as to be inclined to smoothly flow down.

In addition, in the second embodiment of the present invention shown in FIG. 11, the horizontal row lines 20 are arranged in a rhombic lattice shape in the basic technical configuration, and a pair of connecting bands 40 are integrally formed at both sides. The mesh is formed, and the middle intermediate portion exemplifies a mesh in which the longitudinal line 10 is disposed.

Here, it is noted that the connecting strip 40 can be replaced by a row of rows 10.

Since the use method of the present invention configured as described above is similar to the conventional mesh, detailed description thereof will be omitted.

On the other hand, it is preferable that the nonwoven fabric is attached to the upper surface of the mesh of the present invention. This is to allow the rainwater to penetrate and flow only in the runway grooves 21 and the longitudinal channel grooves 11 without inflow of soil.

As described above, the mesh of the present invention is very useful for effectively draining the rainwater falling on the slope without local disruption limited to only that portion, which does not interfere with the overall function of the mesh.
