Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reinforces a levee that is likely to be destroyed, and is used to prevent inflow of water after the breach. Regarding usage.

[0002]

2. Description of the Related Art (Reinforcement Method 1) FIG. 28 is an explanatory view showing a conventional embankment reinforcement method. 28, the embankment 1
01 on the surface of the river 111 side is scourd by the water flow to form the recess 104, and the dike 10 is formed in the recess 104.
When it is judged that there is a risk of collapse of No. 1, a concrete block is arranged in the recess 104 dug out by the scouring to reinforce the embankment 101. At this time, the concrete block 120 is transported from a predetermined stockpiling place and dropped directly from a transportation truck or placed by a crane 121. Therefore, the arranged concrete blocks 120 prevent the water flow from directly hitting the bank surface, and suppress the progress of the scouring.

(Reinforcement method 2) FIG.
It is explanatory drawing which shows the reinforcement method of the embankment disclosed by 120038 gazette. In FIG. 29, an appropriate container 102 is filled with concrete from a concrete truck 110, and the container 102 filled with the concrete is left by the crane truck 109 while the concrete is in an uncured state.
It is arranged in the recess 104 which has been scooped out by the scouring of No. 1.
Further, the wire 107 is connected to the pile 108 to prevent the washout. Therefore, the uncured concrete is solidified along the shape of the recess 104, so that the recess 104 is easily and satisfactorily filled, and the bank 101 is reliably reinforced.

(Reinforcement method 3) FIG.
It is a top view which shows the concrete block connection body disclosed by 110168 gazette. In FIG. 30, a concrete block connecting body is a plurality of concrete blocks 1.
It is configured by arranging 100 in a grid pattern so as to form a plane and connecting them. Each concrete block 1100 has a pair of rebars 1200 embedded therein, and both ends of the rebars 1200 project on the peripheral surface of the concrete block 1100 to form four hooks 1300. The adjacent hooks 1300 are connected to each other by a connecting ring 1400. At this time, each concrete block 1100 is configured to be rotatable about the connecting ring 1400 within a range in which adjacent concrete blocks 1100 do not contact each other.
Therefore, when the flat concrete block connection body is installed on a slope such as a river, each concrete block 1
No. 100 is a retaining wall as a slope cover which can cope with unevenness of slopes, changes in inclination, bending force due to water pressure, etc. and has good workability and durability.

[0005]

By the way, when a river is flooded by a typhoon and a heavy rain (hereinafter referred to as an emergency), first of all, it is necessary to prevent the bank from breaking.
If the levee breaks, it is essential to promptly close the breach site and close it. Moreover, in an emergency,
The river has not only a large flow volume but also a very high flow velocity (hereinafter referred to as a high-speed flow), and it is easy to bring in the corresponding materials to the predicted collapse site or the damaged site itself, for example, to secure roads and trucks. It has difficult problems such as not being. For example, the reinforcing method 1, 2 or 3
However, there are the following problems when trying to apply in an emergency.

(Problem of Reinforcing Means 1) Since the concrete block of the reinforcing means 1 is transported from a predetermined stockpiling place, it is predicted to collapse in order to quickly transport it in an emergency or to avoid the risk of breaking the transportation route. It is necessary to store a large amount (hundreds to thousands) of the concrete blocks near the location. However, the concrete block is usually a wave-dissipating root-fixing block having a complicated shape, and it cannot be piled up and stored in multiple stages to facilitate quick payout. There is a problem that a large storage area is required due to the one-tier arrangement. Further, since the stockpiling place is isolated from the surrounding area as a restricted area, there is a problem that a special dedicated place is required. In addition, the landscape in which such wave-dissipating root block blocks are complicated is not suitable for the surrounding environment, and it is difficult to secure a stockpiling place especially near rivers in urban areas. is there.

In addition, when installing in an emergency river to prevent collapse, a concrete block with a weight of about 2 to 3 tons is swept by a high-speed flow, and desired reinforcement cannot be obtained. There is a point. Especially when installed on a relatively shallow recess where scouring has not progressed so much or on a nearly flat slope, the installed concrete block has a shape consisting of protrusions and gaps, so the flow direction due to high-speed flow There is a problem that the risk of being directly received by the force (hereinafter referred to as the traction force) and being washed away is high. Furthermore, even if the block is installed in an emergency river and the breakage point is closed early, there is a problem that the concrete block is washed away as described above.

(Problem of Reinforcing Means 2) Reinforcing means 2 requires a container (presumed to be a flexible bag) and ready-mixed concrete. It is necessary to store these near the location. However, since the existing ready-mixed concrete supply base is not necessarily installed near the site of predicted collapse, considering the risk of the transportation route from the supply base of ready-mixed concrete to the site of predicted collapse being cut off, the reinforcement means 2 There is a problem that it is difficult to be a reinforcing means in an emergency. In addition, since the containers cannot be stored outdoors, it is necessary to install a dedicated stockpiling warehouse.

When installing in an emergency river to prevent collapse, since the ready-mixed concrete in the container is installed in an uncured state, it takes time to cure and lacks promptness, and In the case of damage, there is a problem that the uncured ready-mixed concrete easily flows out, and desired reinforcement cannot be obtained.

Furthermore, when installing in a river in an emergency and shutting down the breaking point early, in order to pile up similar containers on the container filled with uncured ready-mixed concrete, the containers on the lower stage side should be stacked. There is a problem in that the uncured ready-mixed concrete is easily washed away and the desired deadline cannot be achieved when the container is damaged.

(Problem of Reinforcing Means 3) Similar to the above-mentioned reinforcing means 1, it is necessary to stock a large amount of concrete blocks in the vicinity of the predicted collapse point. However, since the concrete block itself has a substantially football shape and hooks as locking portions project in all directions, it is difficult to stack the blocks in multiple stages, and the concrete blocks are usually placed on the ground (one stage arrangement), There is a problem that a vast storage area is required. Further, since the stockpiling place is isolated from the surrounding area as a restricted area, there is a problem that a special dedicated space is required. In addition, such a landscape in which huge footballs with skewered bars are accumulated is not suitable for the surrounding environment, and it is difficult to secure a stockpiling place especially near rivers in urban areas. .

In addition, when installing in an emergency river to prevent collapse, especially when covering a relatively deep recess where scouring has progressed with the concrete block connecting body connected in a substantially planar shape. Therefore, some concrete blocks will not be grounded on the bottom of the recess. Therefore, the water pressure of the rapid flow applied to the concrete block unit is concentrated on the connecting ring and the hook as the engaging portion with the adjacent concrete block unit, so that the connecting ring or the hook is broken and the concrete block unit is broken. There is a problem that a simple substance is lost. On the other hand, even when the concrete blocks are installed on a substantially flat slope, vortices are generated in the concave portions between the concrete blocks, so that the individual concrete blocks receive the traction force due to the rapid flow, and the connecting ring or There is a problem that the hook breaks.

Further, even when installed in a river in an emergency and shutting off the breaking point early, there is a problem that the connecting link or hook is broken as in the case of the above-mentioned reinforcement. Further, since the connected concrete block is formed in a substantially flat surface, there is a problem that an appropriate deadline corresponding to the breaking mode of the breaking point cannot be obtained.

The present invention has been made in view of the above-mentioned conventional problems, and by making the locking means a rectangular parallelepiped housed in a recess, it is in harmony with the surrounding environment and is regular in a small area. An object of the present invention is to provide an embankment stockpiling block and a method of using the same, which can be piled up and stockpiled in a pile and can surely and promptly respond to the breakage and the deadline of the breaking spot.

[0015]

According to a first aspect of the present invention, there is provided a through hole , wherein at least one outer surface is flat, a recess is formed on the outer surface excluding the flat portion, and each ridge line is chamfered .
The rectangular parallelepiped is a rectangular parallelepiped that is not provided with locking means installed in the recessed portion, and when the blocking means is used to prevent breakage of the embankment or to prevent inflow of water after the breakage of the embankment, a plurality of the rectangular parallelepiped are used as locking means. It is characterized in that it can be bent or rotated in a substantially triangular shape through a pipe to be introduced into a predetermined position of a river. The invention according to claim 2 is installed on a bank of a river or the like, and is stockpiled for the purpose of preventing the bank from breaking or preventing the inflow of water after the bank breaks. A method of using, the step of regularly stacking and storing the dike stockpiling block in the vicinity of a river or at a predetermined disaster prevention base, and a plurality of the dike stockpiling blocks that have been stockpiled. A step of connecting the locking means installed on the block with a connecting member so that they can be bent or rotated in a substantially triangular shape, and the connected embankment storage block,
It is characterized by having a step of putting it into a predetermined position of a river.

(Installation Form) FIG. 23 is an explanatory view showing a form in which the bank storage block according to one embodiment of the present invention is installed at a predicted collapse site of a river in an emergency. In FIG. 23, a plurality of connecting blocks 4a are installed in the scoured recess 8 on the slope 7 of the embankment of the river 6. Therefore, since the connecting block 4a has a predetermined weight, a high-speed flow in an emergency (for example, a flow velocity of 5 m / s or more)
It will not be washed away at. Also, the connection block 4
Since the a's are intertwined with each other, it becomes more difficult to flow them, and for example, they can be stacked even at a water depth of 3 m or more.

The connecting block 4a of the present invention has the above-mentioned 3
The present invention is not limited to the connecting block, and any of the connecting blocks may be installed depending on the situation of the site in an emergency. Also, different types of connection blocks may be installed together. Furthermore, when the connecting hardware is allowed to bend or rotate between the individual blocks, the connecting block 4a is grounded along the shape of the recess 8, so that the recess 8 can be filled even better.

FIG. 24 is an explanatory view showing a mode in which the bank for embankment storage according to one embodiment of the present invention is installed at a predicted location of river collapse in an emergency. In FIG. 24, the slope of the embankment of the river 6 which is indicated by a solid line in normal times recedes to the slope 7 which is scour-filled and is indicated by a chain line, and from the slope 7 to a substantially horizontal plane 9 of the river or riverbed. A plurality of connecting blocks 4b are installed across. It should be noted that the connecting block 4b is separated from the slope 7 and the substantially horizontal surface 9 in front of
It may be piled up in a pile.

FIG. 25 is an explanatory diagram showing a form in which the bank storage block according to one embodiment of the present invention is installed at a predicted collapse location of a river in an emergency. In FIG. 25, a scoured recess 8 is formed on the slope 7 of the embankment of the river 6.
16 to the substantially horizontal plane 9 of the river or riverbed, first, in the first layer, a connecting block 4c in which 5 units of the 3 unit connecting block shown in FIG. On the second layer above, a connecting block 4d in which three more H-shaped three-unit connecting blocks are connected is installed, and rubble stones 10 are installed in the gaps between the single blocks constituting these. .

Therefore, since the connecting block 4c and the connecting block 4d have a sufficiently heavy weight, the connecting block 4c and the connecting block 4d are not swept even in a high speed flow in an emergency. Further, since the rubble stones 10 are installed in the gaps between the single blocks forming these, the slope 7 of the embankment is cut off from the flow of the river, so that the scouring of the slope is prevented, and the single block Since vortices are rarely generated between the blocks, the individual blocks are less likely to receive the traction force due to the high-speed flow of the river, and damage to the connecting fittings is prevented.

The present invention is not limited to the above-described embodiment, and the connecting block 4c and the connecting block 4d are not formed in the recess 8 but in the river in front of the recess 8 or in the substantially horizontal plane 9 of the riverbed. You may pile up in a shape. Further, the connecting block 4c and the connecting block 4d are not limited to those in which the above-mentioned 3 unit connecting block is further connected, and any of the above connecting blocks may be used, and the number of connected single blocks is not limited. Good, also
It is also possible to connect different types of connection blocks to each other.

FIG. 26 is an explanatory view showing a mode in which the bank storage block according to one embodiment of the present invention is installed at a predicted collapse location of a river in an emergency. In FIG. 26, a connection block 4e that is connected in a flat shape is installed on the slope 7 of the embankment in a state where scour on the slope 7 of the embankment has not yet progressed.

Therefore, the connecting block 4e does not become an obstacle to the rapid flow of the river and does not raise the water level of the river. Further, since the individual single blocks constituting the connecting block 4e are connected to each other in abutment or close to each other, almost no vortex is generated between the individual blocks, so that the individual single blocks generate traction force due to the high-speed flow of the river. It is less likely to be received, and damage to the connecting fitting is prevented.

In particular, when the connecting block 4e having no recess on the upper surface side is formed by using a single block having a flat surface (no recess is installed), the flow of the river is not obstructed. The traction force due to the high-speed flow acting on the individual unit blocks themselves constituting the connecting block 4e is further reduced, so that the installation stability is improved. Also, at the time of connection, if bending or rotation between single blocks is allowed,
Since the single block is grounded along the ups and downs of the dike slope 7 and the slight unevenness, the dike slope 7 can be well covered.

As described above, in FIGS. 22 and 25, the form in which the predicted collapse portion of the river is reinforced in an emergency has been described. However, the form in which the collapsed portion is closed after the collapse is similar to this, and the recessed portion is the same. You can read 8 as the broken point.

[Embodiment 2] Next, a method of using the bank storage block according to another embodiment of the present invention will be described in detail. FIG. 27 is a flow chart showing a method of using the bank for embankment storage according to another embodiment of the present invention. In FIG. 27, the method of use includes a stocking process of a single block or a linked block, a forming process of the linked block, a setting process of the linked block, and a withdrawal process and a stockpiling process of the installed linked block.

(Storage Step) The single block or the connection block described in the first embodiment is replaced by the first embodiment.
The stocks are stored in the stockpiling form described in. At this time, the stockpiling place is near a river or a predetermined disaster prevention base, and the single block and the connection block are stockpiled in the surrounding landscape environment and the local community as described above.

The disaster prevention base can be used as an evacuation site, a base for rescue activities, a heliport, etc. in the event of an emergency such as a flood, etc., and is prepared so that it can be used for recreation, community space, etc. for multiple purposes during normal times. Is. That is, for the above reason, the single block or the connected block can be stored in harmony in the disaster prevention base, for example, in the green space park in the base.

(Step of forming a connecting block) A plurality of the stocked single blocks are appropriately connected to form a connecting block according to an emergency situation. In addition, it may be formed in advance in normal times and stored in the form of a connection block.
The form of the formation is the same as that of the connecting block described in the first embodiment. The formation may be carried out in a stockpiling place or near a place to be installed (a place near a river). That is, the connection block can be appropriately selected in consideration of the ease of transportation, the form of installation, the urgency of installation, and the like.

(Installation process) A connecting block formed in an emergency or a connecting block previously formed and stored in advance is blocked at a place where breakage of the embankment should be prevented or inflow water after the breakage of the embankment. Install it in the right place using a crane. The installation form is the same as the installation form described in the first embodiment.

(Removal and Restocking Process) After an emergency has passed, the connecting block installed in an emergency is often used continuously in the installed state, and is usually removed. Absent. However, when the embankment is restored, the connected blocks that have been installed can be removed from the installation site and those that can be reused can be stored again. In this case, the removal work can be easily carried out by suspending a rope or the like on a retaining means or a coupling fitting installed on the coupling block and lifting the rope.

The stockpile may be the connected block as it is or a single block after the connected block is separated. The form of the stockpile conforms to the stockpile process. The connecting block can be easily separated into a single block by opening or removing the connecting fitting.

[0056]

As described above, according to the present invention,
Since the storage block for embankment is a rectangular parallelepiped with the locking means stored in the recess, it is harmonized with the surrounding landscape environment and fused with the local community, and it is piled up regularly to make a large amount in a small storage area. It has a remarkable effect that it can be stockpiled.

Further, since the installation form of the locking means can be properly designed, a connection body of the bank for storage blocks having a desired shape and a desired weight can be formed. Alternatively, a remarkable effect that the inflow of water can be prevented is achieved.

Further, since it can be easily lifted up through the locking means or the connecting fittings installed in the connecting body of the bank for storage of levees, it can be easily withdrawn during restoration work, and the stockpiling can be done again. It has a remarkable effect that it is easy.
