INSTRUCTIONS OF THE INVENTION [Technical Field] The present invention relates to a submersible block for submarine cable protection, in particular, two between the mainland and the mainland, between the land and the island, and the like. Between the ground, the cable laid on the seabed for communication is damaged in the fishing area where the fishing is active, because the anchor or the fishing gear laid on the seabed to form a fishery near the coast is damaged, so the bed is placed above the submarine cable. A matress block is connected to form a sinker to prevent damage to the submarine cable. [Prior Art] Generally, a sinker for preventing damage to a submarine cable is generally constructed by first laying a cable on the seabed, installing a hollow mat thereon, and injecting concrete through an injection hole formed in the hollow mat. Cables are protected by covering submarine cables. However, this method has the problems of complicated construction and high construction cost. In addition, as shown in FIG. 5, another method is to connect the sleeper-like rectangular concrete block 30 which has been previously made on the land to form a sinking bed 300, and cover it on the upper surface of the submarine cable, thereby preventing the seabed. The cable 40 is destroyed and the construction cost is reduced. However, the above-mentioned sinking bed formed by directly injecting concrete is an integral structure formed by filling concrete inside the hollow mat, and therefore, it is easy to pass through various fishing gears for fishing activities near the coast, and the fishing gear is directly contacted and Destroy the submarine cable. Or, if the fishing gear penetrates into the joint between the sleeper-like rectangular concrete -5 - (2) (2) 200803102 concrete block 30, it will directly contact and damage the cable. SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a sinker block for protecting a submarine cable. That is, in order to prevent damage to the submarine cable, the sinker is laid on the upper surface of the submarine cable, thereby enabling the cable to be protected from the damage of the anchor and various fishing gears. For this reason, the present invention has a protruding portion and a step portion. In a combined manner, the bed and the sinker block which are cured by the concrete are connected, and no space is generated at the joint portion thereof, so that even if the anchor or the fishing gear penetrates into the joint portion of the sinker block, that is, between the concrete block and the block, It is also formed in the stepped portion of the sinker block, thereby protecting the cable. In order to achieve the above object, the present invention adopts the following technical means. That is, the present invention provides a sinker block for curing concrete by preventing damage to the submarine cable. Wherein the sinker block is integrally formed by an upper unit and a lower unit, the upper unit forming a protrusion above the lower unit, thereby protruding from the lower unit in a lattice shape, and thereby forming a step portion in the lower unit The invention connects the connecting portion of the sinker block for protecting the submarine cable by combining the protruding portion and the step portion, whereby even if the anchor or the fishing gear used on the fishery passes through the connecting portion, the card is made Living on the stepped section of the lower unit of the sinker block prevents damage to the submarine cable, saving construction costs for re-construction of the submarine cable. [Embodiment] -6 - (3) (3) 200803102 The present invention will be described in more detail below with reference to the accompanying drawings. The present invention is a sinker block 10 for protecting a submarine cable from being damaged by concrete, and the sinker block 10 is integrally formed by an upper unit 11 and a lower unit 12, and the upper unit 11 is formed above the lower unit 12. The protruding portion 13 is formed so as to protrude from the lower unit 1 2 in a lattice shape, and thereby the step portion 14 is formed in the lower unit 12. Further, the present invention forms a groove 101 at the center of the periphery of the upper unit 1 1 , and the groove 101 is integrally formed with a connecting ring 102. And through the connecting member 20, the sinker block 1 is connected to each other around it, and thereby constitutes a sinker. The functional effects of the present invention having the above structure will be specifically described below. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing a sinker block for protecting a submarine cable according to the present invention, Fig. 2 is a front view of a sinker block for protecting a submarine cable according to the present invention, and Fig. 3 is a plan view showing a sinker block for protecting a submarine cable according to the present invention. The sinker block 10 of the present invention structured as above is a quadrangular structure which is cured by concrete and which is integrally formed by the upper unit 1 1 and the lower unit 1 2 . At this time, the upper unit 1 1 is formed at the upper end of the lower unit 12, and is in a state of being pushed away from the lower unit 12 in the diagonal direction, that is, in a lattice-like state. That is, the upper unit 1 1 is formed in a lattice shape to form the protruding portion 13 , and the lower unit 1 2 is formed with the lattice-shaped step portion 14 . Further, a groove 101 is formed around the upper unit 11, and a coupling ring 102 is integrally formed inside the groove 101. The sinker block 10 of the present invention structured as above is cured by concrete, and therefore 200803102 (4) In order to maintain its tensile strength, reinforcing steel is provided inside. Thus, in order to interconnect the various sinker blocks 10 of the present invention which are conserved by concrete, as shown in FIG. 4, the connecting members 20 are connected to form the grooves 1 0 1 of the upper unit 1 1 of the sinker block 10 The connecting ring 1 〇 2 and the connecting ring 102 on the other sinker block 10 thus constitute a sinker 1 . At this time, although the connecting rings 1〇2 of the different sinker blocks 10 are connected by the connecting member 20, the protruding portions 13 formed on the upper unit 11 of the sinker block 10 are placed on the other sinking block 1 to be connected. The lattice-shaped step portion 14 of the lower unit 1 2 is formed on the crucible. That is, the lattice-like projections 13 formed on the upper unit 1 1 of the sinker block 10 are placed on the lattice-like step portion 14 formed on the lower unit 1 2 of the other sinker block 10, thereby The steps are connected to each other to form a sinker. If the upper part of the submarine cable 40 is covered by the above-mentioned sinker 100, the anchor or the fishing gear used on various fishing grounds is placed on the seabed, even if it passes through the sinking bed covered in the submarine cable for connecting the block 1 Between the 单元 and the upper unit 1 1 of the block 1 ,, it is also caught by the step portion 14 of the lower unit 1 2, so that it does not directly contact the submarine cable, thereby protecting the submarine cable from damage. .
