The stormwater drained into the stormwater is drained to the stormwater channel through the connecting pipe.

However, as described above, the grating is intended to facilitate the smooth inflow of the rainwater and the maintenance of the rainwater, etc., but clogging may occur due to foreign matter such as soil and fallen leaves from the surroundings, There is a problem that the place of the garbage such as a cigarette butt becomes a place of speculation.

Further, the upper surface of the sidewall is inclined at an angle larger than that of the road so that the cross section thereof can function as a drainage with respect to the number of road surfaces, so that the bicycle running at the edge of the road is at risk of running, In particular, in the case of crating damage at the top of the superior level, a safety accident such as the wheel of the vehicle is released may occur.

On the other hand, on the opposite side of the road of the above-mentioned sidewall, a curbstone (curbstone) is provided to divide the sidewalk from the sidewalk. The boundary stone not only induces a drainage on the road surface but also serves to protect the pedestrian by preventing the vehicle from escaping and guiding the driver to clarify the distinction of the traveling road by guiding the traveling direction. These barriers are typically constructed and installed with an L-shaped view.

Therefore, in the case of damage to any part, both the L-shaped cross-section and the boundary stones must be replaced at once, and all of them must be re-constructed at the time of maintenance work on either the roadway or the sidewalk, thereby wasting resources and hurting the environment have.

However, in order to obscure or obscure the technical idea of the present invention due to the detailed description of the known structure in describing the present invention, the description of the structure of the above known structure will be omitted.

FIGS. 2 and 3 are a cross-sectional view and a perspective view of a multi-structure provided on the roadside of a car according to an embodiment of the present invention, and FIG. 4 is an exploded perspective view of the multi-structure.

As shown in FIGS. 2 to 4, the multiway structure of the present invention includes a box-type PC conduit 100 installed at a boundary line between roads, and a boundary stone (not shown) assembled to the box-shaped PC conduit 100 by a bolt- 200).

The box-type PC conduit 100 includes a lower plate 130 and a side plate 120 vertically formed on both side surfaces of the lower plate 130 so as to form a drainage passage 140 in which a flow of stormwater is maintained. And an upper plate 110 covering an upper portion of the upper plate 120.

The drainage passage 140 formed by the inner surfaces of the lower plate 130, the side plate 120, and the upper plate 110 may have a shape in which the cross section gradually increases toward the direction in which the storm flows.

The upper surface of the upper plate 110 is provided with a trench 111 for guiding the road surface road to the drainage passage 140, as well as an installation groove 113 for installing the boundary stone 200.

The trench 111 is formed in the longitudinal direction of the box-shaped PC conduit 100 in the vicinity of the installation groove 113 and is formed with respect to the entire length of the upper plate 110 so that the trench 111 provided in the adjacent box- 111), thereby enabling rapid drainage of the excellent by the line drainage method.

For this purpose, the trenches 111 are provided at regular intervals with discharge holes 111a communicating with the drainage passages 140 at regular intervals.

Accordingly, in the present invention, the number of road surfaces can be drained by the line drainage method, which is advantageous in that the width of the drainage opening can be made as small as possible. For example, in the case of installing a conventional superior receiver, a width of at least 40 cm is required. In the present invention, a width of about 10 cm is sufficient.

 As described above, according to the present invention, the width of the trench 111 formed on the upper surface of the upper plate 110 is significantly reduced compared with that of the grating provided by the conventional point drain method, The risk of bicycle riding, the difficulty of accessing the vehicle to the road edge, and the like can be solved.

The top surface of the top plate 110 provided with such a trench 111 is configured to have a downward sloping surface toward the sidewall so that the inflow of storm drained from the roadway to the trench 111 can be performed quickly.

In addition, since the number of roads is multiples of the number of roads as described above, it is not necessary to provide the excellent flow path between the boundary stones 200 by increasing the transverse inclination, unlike the conventional L-shaped sidewall . Therefore, it is preferable that the downward inclined surface formed on the upper surface of the upper plate 110 is matched with the transverse inclination angle of the roadway, thereby securing a greater safety of use on the road edge.

On the other hand, heavy rainfall and heavy snowfall have been greatly increased due to recent extreme climatic phenomena caused by global warming. In order to prevent snowing and freezing of winter roads, spraying of chlorides such as calcium chloride or sodium chloride is common.

However, such chloride damages the surface of the concrete, and the cracks of the concrete caused by this cause corrosion of the reinforcing bars in the concrete, thereby reducing the durability of the concrete structure.

Accordingly, in one embodiment of the present invention, a salt resistance layer 110a is further formed on the top plate 110 exposed to the outside of the box-shaped PC conduit 100 to prevent the deterioration of durability such as deterioration damage.

The flame-retardant layer 110a prevents chlorides dissolved in the road surface water from penetrating into concrete. The flame-retardant layer 110a may be formed by applying a waterproofing agent to the surface of the concrete on the upper surface of the upper plate 110, The admixture made of at least one of blast furnace slag, fly ash, silica fume, and meta-kaolin is usually mixed with the Portland cement.

Depending on the width of the trench 111, a drain cover 112 may be further provided on the trench 111. When the drain cover 112 is installed as described above, the drain cover 112 needs to have a plurality of inlet holes 112a. The inlet hole 112a has various patterns, In addition, it can be used as a means to enhance the appearance of the road.

The roadside multi-structure of the present invention allows the box-shaped PC conduit 100, which is a drainage facility, to be easily assembled to the boundary stones 200 in order to facilitate the replacement of the boundary stones 200. To this end, the upper plate 110 of the box-shaped PC conduit 100 is provided with an installation groove 113 for installing the observer 200 as described above.

The above-described assembling structure may be variously configured. For example, although not shown, anchor bolts may be pre-embedded in the box-shaped PC conduit 100.

However, since the box-shaped PC conduit 100 manufactured to be pre-fitted with the anchor bolts in such a manner, the protruded anchor bolts reduce the quantity of the vehicle to be transported per vehicle, thereby increasing the cost. Further, when the anchor bolts collide with each other during the transportation, Or the adjacent box-shaped PC conduit 100 may be damaged due to the anchor bolt. This may cause a reduction in workability and precision of installation in the field.

Preferably, the installation groove 113 is provided with a first fastening hole 113a communicating with the drainage passage 140 through the upper plate 110, and corresponding to the installation groove 113, And the second fastening hole 200a passing through the upper and lower bores 200 is also formed in the interstice 200 to be fitted, thereby solving the problem of transportation and construction by the upper anchor bolt. Of course, the second fastening hole 200a should be in communication with the first fastening hole 113a formed in the mounting recess 113. [

The assembly of the boundary stones 200 provided with the box-shaped PC conduit 100 and the second fastening holes 200a provided with the first fastening holes 113a may be performed by a general bolt fastening method. However, in this case, the operator must enter the drainage passage 140 of the box-shaped PC conduit 100, but the operator can not enter and exit the drainage passage 140 depending on the size thereof. There is a problem that air can be delayed because communication with an external worker can not be smoothly performed with respect to a work position and the like with respect to a large amount of bolt fastening.

Therefore, according to another embodiment of the present invention, the above-described assembling structure can be realized by a special bolt fastening method which can be performed only by an external work, thereby solving the above-mentioned problems according to a general bolt fastening method, So that the box-shaped PC conduit 100 and the barrier 200 can be efficiently assembled.
