Generally, revetment blocks are installed on coastal, harbor, and riverside slope so that levees and roads are prevented from being lost by waves or water and that the coasts are not eroded. Especially on the coast, erosive action is taking place throughout the four seasons due to weather conditions such as storm and continuous wave energy or tide.

In the existing coastal ports and harbors, a breakwater such as tetrapods or a block of shore protection was installed to prevent the erosion of the coast and to protect the facilities located near the shoreline from the waves. However, And the like. Therefore, in order to restore the coast ecologically and provide it as a resting place for the citizens, various types of shore blocks are installed on the slopes of the coast to enhance the accessibility of the public and create an ecological environment. Among them, A shore protection block formed by stacking in a stepwise manner is widely manufactured and used.

Since the conventional stepped shore block 100 installed on the waterfront is made of concrete and its weight and size are equivalent to each other, a mold capable of producing a shore block is installed on the construction site, As shown in FIG. 1, the anchor 200 is installed in the revetment block 100 to move the constructed revetment block to the installation site.

To remove the anchor 200, the anchor 200 must be cut, Additional surface finishing should be done to cover. Since the shore blocks installed on the shore are mostly installed in a large area, additional finishing work for each shore block causes delays in the construction period, resulting in an increase in cost and a decrease in work efficiency. Particularly, when the stair-step type revetment block is not finely finished, the upper surface 101 is formed ruggedly and it is impossible to provide space for people to sit on. Therefore, The purpose of the stepped revetment block is not attained.

Further, the detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

Referring to FIGS. 2 to 5, a stepped revetment block having a conveyor according to an embodiment of the present invention will be described. A stepped revetment block 1 having the conveyance hole formed therein is referred to as a 'revetment block' Is formed by stacking stepwise in order to prevent erosion of a slope in a river or a coastal area and providing a rest space to the general public. The upper surface forming the upper surface of the shore block 1, (11); A bottom portion 13 forming the bottom of the shore block 1; A circumferential surface 15 which forms a circumference of the revetment block 1 between the upper surface portion 11 and the lower surface portion 13 and includes a front surface portion 151, a rear surface portion 153 and a side surface portion 155; And a conveying hole 17 formed through the front part 151 and the rear part 153. The conveying hole 17 is provided with a conveying means such as a rod or belt for moving the reed block 1, (C) can be inserted.

The upper surface portion 11 forms the upper surface of the revetment block 1 and is formed as a flat surface to provide a space in which a person can comfortably sit. Since the revetment block 1 is conveyed through the conveying means C inserted into the conveyance hole 17, it is not necessary to install or remove an anchor on the upper surface portion 11, A flat surface can be formed. In addition, the upper surface portion 11 includes a non-slip tuck 111 which is inclined downward from a certain point toward the rear side.

As shown in FIG. 3, the non-slip tails 111 are formed at the rear of the portion where the person can sit and are inclined downward toward the rear portion 153. Since the shore protection block 1 is installed on the shore or the like, the upper surface portion 11 is often in a wet state and there is a danger that the pedestrian slips, and water may be formed on the front side of the shore protection block 1, There is also a risk of falling into. Therefore, by forming the anti-slip tails 111 sloping downward on the upper surface portion 11, it is possible to prevent the pedestrian from slipping by allowing the pedestrian to step on the anti-slip tails 111 when raising or lowering the step revetment block 1 can do.

The lower surface portion 13 forms the bottom surface of the revetment block 1 and is preferably formed to be horizontal with respect to the ground surface, but is not limited thereto. The bottom portion 13 is seated on the foundation slope and the bottom portion of the bottom portion 13 is filled with stones and the like so that the revetment block 1 can be stably supported. Therefore, if the upper surface portion 11 of the lower surface portion 13 is horizontally aligned with the ground surface, the lower surface portion 13 can provide various angles according to the inclined surface angle.

The circumferential surface 15 forms a circumference of the revetment block 1 between the upper surface portion 11 and the lower surface portion 13 and includes a front surface portion 151, a rear surface portion 153, and a side surface portion 155 .

3, the front part 151 forms a front surface of the revetment block 1. The front part 151 is formed through the conveying hole 17 and includes a protruding part 151a protruding forward, As shown in FIG.

3, the protrusion 151a protrudes forward from the upper surface portion 11 of the revetment block 1 and is formed to have a predetermined thickness downward. As shown in FIG. 5, the conveying means 17 is inserted into the projecting portion 151a, and the conveying means C is inserted into the conveying hole 17 to lift and move the revetment block 1 At this time, a shearing stress is generated in the inside of the revetment block 1 by the load of the revetment block 1. Therefore, the length of the revetment block 1 which resists the shear stress is increased corresponding to that of FIG. 3 (a) by forming the through hole 17 in the protruding portion 151a, So that the strength and strength of the revetment block 1 can be prevented from being cut or broken. 4, a plurality of protrusions 151a having the same shape can be formed, and a carrier hole 17 is formed in each of the plurality of protrusions 151a, (1) in a balanced manner.

Further, it is preferable that the protrusion 151a is formed to be protruded forward and rounded. Since the revetment block 1 is formed so as to withstand strong waves, the protrusion 151a, which is to be hit by the waves, is formed to be rounded, Energy is dispersed to both sides to be lost. In addition, by forming the projecting portion 151a in a round shape, a person sitting on the revetment block 1 can closely contact the legs on the projecting portion 151a so as to sit comfortably. The protruding portion 151a has a first protruding surface 151a-1 formed to be vertically bent downward from the top surface portion 11 and a second protruding surface 151a-1 extending from the first protruding surface 151a-1 to be inclined rearward And a second projecting surface 151a-2.
