According to the present invention as described above, a waterproof mat is installed inside the river bank, grouted and reinforced by using cement on the side of the bank in contact with the river, and the waterproof non-woven fabric and stones are formed thereon to form a leak of the bank. It can prevent it beforehand.

Description

River bank levees with S-shaped mats to prevent leakage {S-TYPE MAT FIXING EMBANKMENT FOR CAUSEWAY WATER LEAKAGE PREVENTION OF RIVER EMBANKMENT}

The present invention relates to a river dike, and more particularly, to a dike provided with an S-shaped mat for preventing a river dike leak to prevent water from penetrating into the river dike.

The levees contain rivers, coasts, lakes, and swamps within certain flow paths to prevent flooding and to protect the coasts and harbors from storms, tidal waves, and waves. Refers to a civil structure. These dikes are protected by grass, stone, concrete and other revetment works, depending on their location and purpose.

On the other hand, the retaining wall is installed on the river bank to prevent the loss of the river bank.

As shown in FIG. 1, an inverted T-shaped retaining wall 1 is installed between the bottom of the river 3 and the embankment 5 on the side of the embankment.

However, as shown in FIG. 2, such a dike may cause water leakage through the dike if the flow rate is increased, such as rainy season or flooding, and the sediment may leak out of the dike due to the leak, causing the dike to collapse.

The present invention is to solve the problems as described above, and to install a waterproof mat inside the river banks, grouting and reinforcement by using cement on the side of the banks in contact with the river and then again laminated waterproof non-woven fabric and stone It is an object of the present invention to provide a levee provided with an S-shaped mat for preventing the leakage of a river levee, which can prevent leakage of the levee in advance.

The present invention for achieving the above object, in the bank of the river; An S-shaped waterproof mat having a plurality of bent portions; Tossa to form a levee by sequentially stacked on both sides of the waterproof mat; A plurality of grouting holes formed on side surfaces of the soil contacted with the stream; Waterproof nonwoven fabric is coupled to the side in contact with the stream of the soil; And it is characterized in that it comprises a stone laminated on the waterproof nonwoven fabric to prevent scour of the soil.

Here, the waterproof mat is formed at both ends horizontally, the straight portion of a predetermined length is bent a plurality of times while having an inclination.

Here, the grouting hole grouts the cement inside the soil.

Hereinafter, with reference to the accompanying drawings the configuration of the embankment in which the S-shaped mat for preventing the leakage of the river bank according to the present invention will be described in detail as follows.

Figure 3 is a side cross-sectional view showing the embankment installed S-shaped mat for preventing the river bank leakage according to the present invention.

Referring to Figure 3, the embankment 100 is installed S-shaped mat for preventing the leakage of river banks according to the present invention, the waterproof mat 110, the earth and sand 120, the grouting hole 130, the waterproof nonwoven fabric 140 And it is formed with a stone (150).

The waterproof mat 110 is formed in an S shape having a plurality of bent portions, and both ends thereof are formed horizontally, and a straight portion having a predetermined length is bent and formed a plurality of times.

The soil sand 120 is sequentially stacked on both sides of the waterproof mat 110 to form the embankment 100.

The grouting hole 130 is formed at the side contacting the river 3 when the soil sand 120 is stacked. Here, grouting cement in the soil 120.

Waterproof nonwoven fabric 140 is coupled to the side in contact with the river (3) of the earth and sand (120).

Stone pasting 150 is laminated to the waterproof nonwoven fabric 140 to the water level of the river (3) to prevent scour of the earth and sand (120).

Hereinafter, the installation method and operation of the embankment in which the S-shaped mat for preventing the leakage of the river bank according to the present invention will be described in detail with reference to FIGS. 3 and 4.

Figure 4 is an exemplary view showing a process of forming a levee is installed S-shaped mat for preventing the river bank leakage according to the present invention.

First, the method of stacking the earth and sand 120, as shown in Figure 4 to pile up the earth and sand 120 to the height of the first bent portion of the waterproofing mat 110, as shown in Figure 4, wherein the waterproof mat 110 To limit the length of the earth and sand 120 to be located in the center of the embankment 100, and forms the same inclined surface as the waterproof mat 110 on the side in contact with the waterproof mat (110).

When the compaction of the first soil layer is completed, the waterproof mat 110 is installed on the inclined surface of the soil sand 120, and the soil sand 120 is piled up on the opposite side of the waterproof mat 110 again, and the first bent portion and two Lay up to the first bend (① process).

Then, piled up and piled on the opposite side of the waterproof mat 110 again, in this case, the first bent to the third bent to the lamination (② process). By inserting the waterproof mat 110 inside the soil sand 120 in this manner, the soil sand 120 is sequentially stacked to complete the mold of the embankment 100 (③ ~ ⑥ process).

On the other hand, when laminating the soil layer in contact with the river (3) in the process of laminating the soil 120 is formed a plurality of grouting holes (130).

In this state, the waterproof nonwoven fabric 140 is installed on the side of the soil 120 in contact with the river 3, and then the stone is laminated by stacking stones from the bottom of the river 3 to the height of the waterproof nonwoven fabric 140. The cement is injected into the grouting hole 130.

Therefore, by installing a waterproof mat inside the dike, and by reinforcing the surface in contact with the river through the waterproofing and grouting it is possible to block the collapse of the dike due to leakage.

According to the embankment in which the S-shaped mat for preventing the leakage of the river dike according to the present invention constituted as described above is installed, the waterproof mat is installed inside the river dike, and the grout is reinforced on the side of the dike in contact with the river. Again, by forming a waterproof non-woven fabric and stones there is an advantage that can prevent the leakage of the embankment in advance.
