Description

BLOCK FOR PROTECTING A RIVER BED}

The present invention relates to a bed protection block, in particular, by fixing a block formed with a protrusion on the upper surface with a pile on the bed, to ease the rapid flow rate during flooding and at the same time increase the amount of dissolved oxygen in the water due to increased aeration action underwater plants It is designed to provide the optimal environment for fish and fish, and to reduce the construction cost by reducing the amount of pile fixing blocks.

In general, the slopes of rivers, rivers, beaches, roads, or parks are constructed with raft blocks to prevent the loss of roads and the role of embankments. A bed protection block has been constructed.

The bed protection block is composed of gabions filled with stones such as large gravel and crushed stone in a wire mesh having a mattress shape, and is configured to prevent the bottom and bottom of the revetment block from being scoured by running water.

However, when a certain time passes after construction, corrosion protection occurs on the coated wire which forms the gabion, and the wire is broken due to the impact generated in the process of colliding with an object floating upstream from the flood. Stones such as large gravel and crushed stone are swept away, and as a result, the bottom of the raft block is scoured.

In order to solve this problem, instead of gabions, it was used to equip the riverbed protection block composed of concrete, and in the space of the riverbed protection block, put aquatic plants such as reeds, buds, strings, etc. Aquatic plants, such as screw, black horse, crucian carp and other submerged plants, are planted, and gravel and crushed stone are also planted.

In this case, the aquatic color adsorbs organic matter or suspended matter from the roots, and oxygen from the root's aeration system causes the microorganisms living in the roots of the aquatic plants to decompose organic matter or suspended matter vigorously and decompose organic matter. Aquatic plants absorb water and suspended substances to purify water, but the bed protection block is not fastened to the top of the bed but is fastened by chains or creeps in the transverse direction. There was another problem that the scour phenomenon occurred as the bed protection block lifted from the bed due to the flow rate.

On the other hand, as a way to solve this problem was proposed a "river multi-function block" of the Korean Utility Model Registration No. 20-0318175 (2003.06.17), the proposed river multi-function block is formed with a space filled with a stone seat in the center And the corner is formed through-hole through the pile, the lower part of the four sides is composed of concrete formed with a support portion to prevent the water and riverbed from being eroded and scoured by running water, but the upper surface is flat As a result, it was not possible to alleviate the rapid flow rate generated during flooding, and no aeration occurred in the flowing water at all times, so that the amount of dissolved oxygen in the water was lowered, making it impossible for aquatic plants and fish to live in the water. There was a problem.

In addition, there was another problem that the aquatic plants are pulled out and lost as the litter and gravel filled with aquatic plants are moved to a high flow rate due to flooding.

In addition, since four piles are required to fix one block to the bottom, there is an uneconomic problem in that the construction cost of the pile is increased.

The present invention has been devised to solve such a problem by fixing a block formed with a protrusion on the upper surface by piling on the lower side,

first; It reduces the rapid flow rate during flooding and increases the amount of dissolved oxygen in the water due to the increase of aeration, so that aquatic organisms grow well.

second; Gravel, crushed stone, etc. can be stacked between the top of the block and the head of the pile inserted into the central pile hole so that the flowing water can hit the stone and supply oxygen by aeration.

third; By forming four through spaces, small through spaces are formed so that the stones in the through spaces do not move even when the flow velocity increases, so planted aquatic plants are not pulled out and lost.

fourth; It is an object of the present invention to provide a bed protection block that can reduce the construction cost by reducing the amount of use of the pile so that the ring-shaped edge protrusion 17 protruding to the upper portion of the pile insertion hole 12.

In order to achieve the above object, the present invention places a unit block having a link ring formed at the corner on the upper surface of a lower bed, and a lower protective block configured to be installed by connecting a link ring located between each unit block with a chain. The unit block has four protrusions integrally formed on an upper surface of the block body, and a pile insertion hole is formed in the center, and four through spaces are provided between the pile insertion hole and the protrusion, and the central pile is provided. The purpose is achieved by providing a bed protective block characterized in that the pile is inserted into the insertion hole is configured to be fixed to the block body on the bed.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in Figures 1 to 4, the lower bed protection block according to the present invention is made of concrete having a predetermined thickness and constructed to cover the upper surface of the lower bed unit having a main function of preventing direct scour by running water. It consists of block 10.

The unit block 10 is formed of a block body 11 having an overall shape of a square shape, and the pile insertion hole 12 having a predetermined diameter is formed in the center of the block body 11, Each corner is integrally provided so that the connecting ring 14 is formed by forming the chamfer 13 to have a predetermined length. In the drawing, reference numeral 30 denotes a chain ring.

The upper surface of the block body 11 provided between the through spaces 15 and 15 ′ and the chamfer 13 has four protrusions 16 having a recess or protruding shape that protrude upward. (16 ') is formed to alleviate the rapid flow rate generated during flooding, and at the same time to allow aeration to occur in everyday life, thereby increasing the amount of dissolved oxygen in the water to grow underwater organisms.

In addition, between the pile insertion hole 12 formed in the center of the block body 11 and the chamfer 13, four through spaces 15, 15 'having a vertically and vertically penetrated form is formed by the crushed stone, It is equipped with stones such as gravel so that planted aquatic plants can live well.

By forming the four through spaces 15 and 15 'in the above, the through spaces 15 and 15' are made smaller than the one through space in the related art, so that the through spaces 15 are increased even when the flow velocity is increased during flooding. Since the stones in (15 ') do not move, planted aquatic plants are not pulled out and lost.

In addition, the protrusions 16 and 16 'in the form of diggers or tracers are formed of stones, gravel, and the like stacked on the upper surface of the block body 11 of the protrusions 16 and 16' and the pile 20 in the form of diggers or tracers. It is divided into four by the protruding head 21.

Accordingly, the stones stacked in four compartments are prevented from being lost due to the supporting action of the protrusions 16 and 16 ′ and the protruding heads 21 of the pile 20.
