Description

Revetment block for a slope of river dike}

The present invention relates to a bank embankment protection block installed on the inclined surface of the embankment formed for the prevention of flooding of the river and the use of water resources, and more specifically to protect the embankment in the form of a lattice frame. The frame is formed by a prefabricated coupling, and between the frame and the surface protection function of the inclined slope of the embankment and the vegetation block having the vegetation function of the herbaceous plant to be assembled into a prefabricated, without the additional equipment to provide a revetment block having excellent protection function A river that enables quick and easy installation, solves various problems exposed to the construction of shore banks, and promotes the early recording of bank slopes by installing vegetation soils of plants and safe support of the vegetation soils. The present invention relates to a bank embankment block.

Generally, rivers, farms, or lakes have levees that have been pledged to prevent flooding of rivers and promote efficient use of water resources. For engineering reasons, such as building a highway for driving various equipment on the embankment, an inclined surface is formed on one side of the embankment, which is in direct contact with the water surface, or an inclined surface is formed on both sides of the embankment.

Since one side or both sides of the dike form an inclined surface as described above, the lower side of the inclined surface of the dike is easily eroded by the flow of the river, and in the case of rain or heavy rain, the sediment of the dike is easily lost to the river or the like along the slope by rainwater. As a result, the supporting strength of the dike is weak, and if the dike is collapsed, serious damage to people or property can be caused, and protection measures are used to prevent erosion of the slope and loss of soil. .

The most typical of the conventional revetment means as described above, the width and length of the width of about 40cm, the thickness of about 10 ~ 12cm, the weight of about 30 ~ 35kg of the revetment block of concrete or mortar made of square or hexagon or It is known to manufacture in various forms, such as an octagon, and to install the bank block produced in this way on the inclined surface of a levee by the method of combining by manpower.

However, the conventional revetment block as described above is made of concrete or mortar material, the weight is relatively heavy, so that the transport and handling of the revetment block is difficult, because each revetment block must be installed in a frame by manpower There was a problem that the installation of the raft block on the slope of the dike was a difficult and difficult task requiring skill. Each area of the raft block had a small contact area with the slope of the dike, resulting in a large number of rafts per unit area. Of course, there is a problem in that the block is installed, such that the bond strength between the mutually installed revetment block is weakened so that the revetment block is separated or lost from the inclined surface.

In particular, the installation of the above-mentioned protection block on the slope of the dike having a large area requires a lot of manpower and a long construction period, which leads to an increase in construction cost and delay of air, and a protection block of concrete or mortar. Since herbaceous plants are not able to grow at all, they interfere with the purification of various pollutants introduced into rivers, causing river pollution, and have problems in harmony with the general landscape of nature.

In order to solve the problems of the above-mentioned concrete or mortar revetment block, the revetment block is made of plastic material, and the groove block through which the claws of various heavy equipment can be formed on both sides of the revetment block of concrete material is formed. Mechanical construction is also known.

However, in the case of the plastic revetment block corresponding to the former, the weight of the plastic revetment block is lighter than that of the concrete block, and the construction and deterioration of the revetment block and the loss or loss of the revetment block are prevented except that the convenience of transportation and handling is slightly improved. In addition to the problems such as the increase in construction cost, delay in construction period, and the inability to plant herbaceous plants, such as problems, the weight of the revetment block is so light that it can effectively protect the bank slope. Additional problems have arisen, such as not possible.

In addition, in the case of the latter, the construction of the revetment block is to be mobilized separate heavy equipment such as cranes or fork lanes for the installation of the revetment block, even if the heavy equipment is mobilized in this way, Not only could not solve the various problems described above, there was a problem that additional obstacles in construction to enter the heavy equipment into rivers or lakes corresponding to the soft ground occurred, and on the highway built on the upper bank Even when constructing a raft block while entering heavy equipment, there was a problem that many difficulties occur in construction of a raft block using heavy equipment because the raft block should be stacked from the bottom of the bank.

The present invention has been made to solve the conventional problems as described above, the river bank banks according to the present invention is formed by the prefabricated coupling of the embankment protection frame of the grating frame type, between the frame of the bank inclined surface By fixing the vegetation block having the vegetation function of the herbaceous plant together with the surface protection function, it is possible to quickly and easily install the revetment block having excellent protection function without any additional equipment, and various problems exposed to the construction of the revetment block. The technical problem is to solve the problem of planting soil and to secure the support of the planted soil.

The present invention for achieving the above technical problem, is installed on the inclined surface of the embankment surrounding the river or lake to prevent the erosion and sediment outflow of the inclined surface, "￢" shaped corner block, straight block and T-shaped The outer frame connected in a rectangular shape by the block is fixed on the inclined surface by the anchor bolt, the cover frame is fixed to the grid connected by the cross-shaped block and the straight block inside the outer frame fastening bolt and anchor bolt It is fixed to the T-shaped block and the inclined surface by respectively, between each block constituting the outer frame and the cover frame, the vegetation block is attached to the rear of the vegetation hole formed over the entire body is attached to the anchor bolt As fixed to the inclined surface, the edge block of the outer frame is rod-shaped through the anchor hole Connection ends and insertion grooves are formed at both ends of the sieve, respectively, and the straight block has connection ends at both ends of the rod-shaped body, and the T-shaped blocks have insertion grooves formed at each cutting surface of the body through which the anchor hole is passed.
