Description

BASE BLOCK FOR CONSTRUCTING TIDE EMBANKMENT
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a base block installed on the bottom of the sea when a tide embankment is constructed, and more particularly to a base block for constructing a tide embankment, which allows a base ground to be effectively constructed at the minimum amount of sand and stone and is simply installed on the bottom of the sea such that the construction of the base ground accompanied by the construction of the tide embankment is rapidly achieved in the shortest time.
Description of the Related Art
In general, the industrial object of tide embankments is to achieve land reclamation and desalination of the maximum area of the sea at the minimum lengths of the tide embankments . Tide embankments are usually constructed at a position of an estuary, in which a tideland, such as a mud flat having the flowing tide, is well developed, or an indentation.
Tide embankments are constructed by several methods including a high sill method, in which a tide embankment is horizontally constructed upwardly from the base thereof, a deed sill method, in which a tide embankment is constructed from both ends thereof, and a combined high and deed sill method, in which a tide embankment is constructed by performing the high sill method and the deed sill method simultaneously. During the tide embankment constructing process through the above various methods, the construction of a base ground on the bottom of the sea is an important point. In a conventional method of constructing a base ground 100 on the bottom of the sea, as shown in FIG. 8, sand and stone 110 having a heavy weight and a large size or concrete blocks molded into a designated shape are continuously carried by a transportation unit 120, such as a dump truck, and are dropped and loaded onto the bottom of the sea.
However, in such a method of constructing the base ground 100 by carrying the sand and stone 110 or the concrete blocks by the transportation unit 120 and dropping and loading the sand and stone 110 or the concrete blocks onto the bottom of the sea, the sand and stone 110 or the concrete blocks dropped onto the bottom of the sea are not smoothly loaded onto the bottom of the sea but are washed away due to the overflow of the tide and the high speed of a water current at the bottom of the sea and, and thus a considerably massive amount of the sand and stone 110 or the concrete blocks must be supplied.
Further, during the process of dropping the sand and stone 110 or the concrete blocks to construct the base ground on the bottom of the sea by the above method, the water current is concentrated due to the reduction of a water flow section to increase the speed of the water current, and thus the sand and stone 110 or concrete blocks having a considerably heavy weight are required.
SUMMARY OF THE INVENTION
Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a base block for constructing a tide embankment, which allows a base ground to be effectively constructed at the minimum amount of sand and stone and is simply installed on the bottom of the sea such that the construction of the base ground accompanied by the construction of the tide embankment is rapidly achieved in the shortest time.
It is another object of the present invention to provide a base block for constructing a tide embankment, which minimizes water hammering due to waves when a base ground is constructed.
It is yet another object of the present invention to provide a base block for constructing a tide embankment, which is more easily fixed onto the bottom of the sea. In accordance with an aspect of the present invention, the above and other objects can be accomplished by the provision of a base block for constructing a tide embankment, which is provided to construct a base ground when the tide embankment is constructed, comprising a main body block provided with a narrow upper portion and a wide lower portion; a hollow part longitudinally formed through the center of the main body block to apply buoyancy to the base block when the base block is carried; and a connection fixing unit formed on the front end surface and the rear end surface of the main body block such that plural main body blocks are interconnected and fixed to each other therethrough.
The connection fixing unit may include a connection groove formed on the front end surface of the main body block, and a connection protrusion formed on the rear end surface of the main body block corresponding to the connection groove.
Both side surfaces of the main body block, which is provided with the narrow upper portion and the wide lower portion, may be bent in a curved shape to be symmetrical with each other with respect to the central line of the base block. A plurality of support bars fixed into the bottom of the sea may be formed on the lower surface of the main body block.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings .
FIG. 1 is a schematic perspective view illustrating a block for constructing a tide embankment in accordance with one embodiment of the present invention.
As shown in FIG. 1, a base block 1 for constructing a tide embankment in accordance with the present invention is provided to construct a base ground on the bottom of the sea when the tide embankment is constructed to achieve land reclamation and desalination of the maximum area of the sea at the minimum length of the tide embankment .
Further, the base block 1 of the present invention is simply installed on the bottom of the sea, and allows the base ground to be effectively constructed at the minimum amount of sand and stone such that the construction of the base ground is rapidly achieved in the shortest time.
The base block 1 of the present invention includes a main body block 10, a hollow part 12, and a connection fixing unit 20.
The main body block 10 is molded in a triangular prism, having a length of approximately 50~80m and a height of approximately 4~9τn, which is provided with the narrow upper portion and the wide lower portion. The hollow part 12, into which air is injected by inserting a tube or air is injected after both side surfaces of the main body 10 are closed to apply buoyancy to the base block 1 when the base block 1 is carried, is longitudinally formed through the main body block 10. The connection fixing unit 20 is formed on the front end surface and the rear end surface of the main body block 10 such that neighboring main body blocks 10 are continuously connected and fixed to each other by the connection fixing units 20. Preferably, the connection fixing unit 20 includes a connection groove 22 formed on the front end surface of the main body block 10, and a connection protrusion 24 formed on the rear end surface of the main body block 10 corresponding to the connection groove 22. Thus, several main body blocks are placed to predetermined positions under the sea using a crane of a tugboat, and are connected by the connection grooves 22 and the connection protrusions 24, and a general adhesive agent, such as epoxy resin or silicon resin, is injected to the connection regions to firmly connect the main body blocks 10.
Preferably, both side surfaces 14 of the main body block 10, which is provided with the narrow upper portion and the wide lower portion, are bent in a curved shape to be symmetrical with each other with respect to the central line, and thus the main body block 10, which is installed on the bottom of the sea, induces water hammering upward along the side surfaces 14 to minimize the water hammering, when the water hammering due to overflow of the tide or waves is generated. Now, the carriage and the used state of the base block of the present invention will be described in more detail, with reference to FIGs. 2 to 5.
First, the main body block 10 of the base block 1 of the present invention provided with the hollow part 12 and the connection fixing unit 20 is obtained by a general molding method using concrete in a dock provided at the seaside to build ships or inspect and repair ships. Preferably, the main body block 10 has a length of approximately 50~80m and a height of approximately 4~9m, i.e., a considerably large size and heavy weight, to minimize movement of the base block 1 due to overflow of the tide or waves when the base block 1 is installed on the bottom of the sea.
When the molding of the base block 1 of the present invention in the dock has been completed, as described above, a general tube 200 to inject air is inserted into the hollow part 12 of the main body block 10, as shown in FIG. 2, and then air is injected into the hollow part 12 through the tube 200 to apply buoyancy to the main body block 10, or both ends of the hollow part 12 formed through the main body block 10 are hermetically sealed by exclusion plates 210, as shown in FIG. 3, and then air is injected into the hollow part 12 to apply buoyancy to the main body block 10.
Thereafter, when buoyancy is applied to the main body block 10, the dock is filled with water and thus the base block 1 of the present invention is floated on the surface of water and is carried to a desired position using a tugboat. After the carriage of the base block 1 to the desired position has been completed, the buoyancy applied to the hollow part 20 of the base block 1 is removed, i.e., the base block 1 is deflated, and thus the main body block 10 sinks under the sea due to its own weight. At this time, the main body block 10 is seated to an exact position using a crane of the tugboat.
Preferably, when the main body blocks 10 are seated on the bottom of the sea in the longitudinal direction, the connection groove and the connection protrusion of the connection fixing unit 20 formed on the front and rear end surfaces of one main body block 10 are firmly connected to the connection protrusion and the connection groove of the neighboring main body block 10, as shown in FIGs. 4 and 5, and then a general adhesive agent, such as epoxy resin or silicon resin, is applied to the connection regions to firmly connect the main body blocks 10 without movement.
When the main body blocks 10 of the base blocks 1 of the present invention are connected in the longitudinal and cross directions, as described above, an accommodation space (S) , on which sand and stone can be loaded, is formed between the side surfaces of the main body blocks 10. Thus, a base ground can be simply constructed without loading a large amount of sand and stone between the main body blocks 10. Since sand and stone are loaded between the main body blocks of the base blocks after the base blocks are installed on the bottom of the sea, it is possible to prevent a large amount of the sand and stone from washing away due to the generation of a high speed water current caused by the concentration of the water current due to the overflow of the tide or the reduction of a water flow section.
Further, since both side surfaces of the respective main body blocks are bent in a curved shape to be symmetrical with each other with respect to the central line of the main body blocks, although water hammering due to overflow of the tide or waves is generated when or after the base blocks are installed on the bottom of the sea, the main body blocks, which have bent side surfaces as well as are considerably large and heavy, induce the water hammering upward from the portions, to which the water hammering is applied, along the side surfaces to minimize the water hammering.
Therefore, when a base ground is constructed using the base blocks of the present invention, the base ground is constructed using the main body blocks of the base blocks on the bottom of the sea and sand stone is dropped and fills the accommodation space formed between the main body blocks without requiring a large amount of sand and stone, and thus the base ground can be simply and effectively constructed in a short time only using the base blocks of the present invention and the minimum amount of sand and stone.
Further, when the tide embankment is constructed using the base blocks of the present invention, the main body blocks 10 of the base blocks 1, which are installed at a deep portion of the bottom of the sea, are provided with iron reinforcing bars for connection, protruded from the upper portions thereof of the main body blocks 10, when the main body blocks 10 are molded. The iron reinforcing bars of the main body blocks 10 are connected, and extensions 40 are formed at both sides of the main body blocks 10 through molds such that the base blocks of the present invention can be used at the deep bottom of the sea without requiring any separate base blocks and thus have excellent compatibility.
FIG. 7 is a schematic view illustrating a base block for constructing a tide embankment in accordance with another embodiment of the present invention.
As shown in FIG. 7, in order to place the lower surface of a base block of this embodiment on a tideland of the bottom of the sea or bury both side ends of the base block under the tideland, when the base block of this embodiment is fixed to the bottom of the sea, and to more firmly fix the base block to the bottom of the sea, the base block of this embodiment includes a plurality of support bars 30, which are formed integrally with the lower surface of the main body block 10 when the main body block 10 is molded and are inserted into the bottom of the sea.
Thereby, when the main body block 10 is seated on the bottom of the sea, the support bars 30 formed on the lower surface of the main body block 10 are stuck into the tideland on the bottom of the sea, and thus are firmly fixed to the bottom of the sea without movement. Thus, the main body block 10 can be firmly fixed to the bottom of the sea without movement even at overflow of the tide, waves, or generation of a high speed water current under the sea.
The base block for constructing a tide embankment of the present invention allows a base ground to be constructed at the minimum amount of sand and stone and is simply installed on the bottom of the sea such that the construction of the base ground accompanied by the construction of the tide embankment is rapidly achieved in the shortest time, thereby minimizing the washing away of the sand and stone and allowing the base ground to be constructed in the shortest time, thus remarkably shortening the overall construction period of the tide embankment .
Further, the base block, which has bent side surfaces in a curved shape, minimizes water hammering due to waves when the base ground is constructed, thereby allowing the base ground to be more stably constructed and more shortening the construction period.
Moreover, the base block is more firmly fixed to the bottom of the sea through the support bars formed on the lower surface of the main body block, thereby minimizing the movement of the base block even by overflow of the tide or a high speed water current.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims .
