Description

TECHNICAL FIELD [0001] The present invention relates to an eco-friendly slope erosion preventive construction method,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ULTRA ECO-MAT ANCHORING eco-friendly slope erosion preventive construction method and, more particularly, to an eco-friendly slope erosion preventive construction method using an eco mat and an anvil on a slope, To an erosion preventive construction method.

There are slope slopes in general rivers, drainage roads, side of roads, sides of mountains and so on. Such slope surface is subject to erosion due to the influence of rainfall and groundwater flow over time, causing surface erosion due to slipping of the surface, and surface loss due to sliding of the slurry occurs, resulting in the dropping of the slurry to the river, drainage road and road side .

Various methods such as the stiffness reinforcement method, the soft reinforcement method, and the surface layer vegetation method are disclosed to prevent the slope surface from falling off due to erosion.

Typically, the stiffness reinforcement method has a method of protecting a slope by installing a concrete mat and a concrete block on the slope.

However, the above-described rigid reinforcement method has a large reinforcing strength but is not environmentally friendly, easily damaged or dislocated at the ground displacement, can not prevent the loss of the soil caused by long-term use, There is a problem that the workability is disadvantageously increased and the construction cost is increased.

The soft reinforcement method is typically a fiber-to-mortar lattice block method in which a high-strength geosynthetic fiber form is filled with cement mortar to form a concrete lattice column.

However, the above-mentioned soft reinforcement method has a disadvantage in that the strength and durability are lower than those of the stiffening method, and also the loss of the soil caused by the long-term use can not be prevented. Since the mortar is not environmentally friendly and the cement mortar must be hardened, There is an increasing problem.

The surface vegetation method includes spraying seeds on the surface of the slope, and stringing.

However, the above-mentioned surface layer vegetation method is environmentally friendly by seed spraying or lathing on the surface of the slope, but the strength is significantly lower than that of the rigid reinforcement method and soft reinforcement method, and the surface layer dropout and sliding are frequently And the long-term durability is weak.

Therefore, it is possible to improve the strength and durability by improving the strength and durability, to effectively prevent the surface erosion of the slope, to prevent the loss of the slope even for long-term use, and to improve the slope of the slope by environment- Development of technology is required.

Both ends of the eco mat 10 can extend to the upper and lower ends. When a drainage path is formed at the upper or lower end of the slope 1, the eco mat 10 may be installed up to the drainage path so that the sinkhole anchor 20 or a landing pin 40 described later or the like may be installed.

The eco mat (10) is made of polypropylene, polyethylene, nylon, polyester, PVC and the like which are excellent in durability, tensile strength and ultraviolet ray resistance, So that the remaining water on the back surface can be drained smoothly, and at the same time, the sheave anchor 20 and the landing pin 40 described later can be easily inserted.

Further, since the eco mat 10 is formed in a three-dimensional woven form, the space between the woven fibers is sufficient, and the sunlight transmittance and the germination rate are excellent, and thus vegetation is excellent.

The sheave anchor 20 may include an insertion pin that is inserted into the ground and then is rotated and fixed, a tension line connected to the insertion pin, and a fixing portion coupled to an end of the tension line to fix the eco mat 10 . That is, the insertion pin connected with the tension line is inserted into the ground with a separate device, and then the tension pin is pulled so that the insertion pin rotates horizontally and is fixed to the ground. Then, the fixing portion is fixed to the upper end of the tension line so that the fixing portion fixes the eco mat 10.

The linear portion 41 causes the landing pin 40 to be positioned at the correct position and at the same time the helical portion 42 is rotated in a stable state. The spiral portion 42 allows the landing pin 40 to be inserted into the ground as the landing pin 40 rotates and at the same time the landing pin 40 inserted in the ground is fixed so that the eco mat 10 is stably fixed. The second linear portion 43 can increase the fixing force of the landing pin 40 by allowing the helical portion 42 to be installed at a sufficient depth. The handle 45 may play a role of allowing the landing pin 40 to be inserted into the ground by applying a rotational force to the landing pin 40 and at the same time fixing the eco mat 10 to the ground.

The spiral portion 42, the second straight line portion 43 and the grip portion 45 of the landing pin 40 are similar to the landing pin 40 described above. That is, the present embodiment is different in that the spiral portion 42 is directly formed without the straight line portion 41.

4C, the landing pin 40 includes a pair of arrows 46, a pair of rectilinear sections 41 extending straight upward from the pair of arrows 46, (45) which is bent at a right angle at a right angle in a pair of straight line portions (41) and which is bent in a direction opposite to each other and formed in a circular shape, is inserted into the ground, have. That is, the pair of arrows 46 may be formed by being bent downwardly and then upwardly. Each of the pair of arrows 46 forms a half arrow, and a pair of arrows are formed to form a single arrow shape. The arrows 46 are easily inserted into the ground and then fixed to the ground. That is, when the landing pin 40 is pulled out, the arrow portion 46 can be firmly fixed to the ground while gradually spreading. The rectilinear section (41) extends straight upward from the arrow section (46) so that the arrow section (46) is fixed deeply in the underground. The handle 45 is bent at a right angle in the pair of straight portions 41 and then moved in the same direction and bent in opposite directions to form one circle. This handle 45 serves to fix the eco mat 10. The landing pin 40 of the present embodiment is provided with a landing pin inserting device 50 having a latching groove 52 for catching a pair of arrows 46 together at its lower end and a striking part 54 at the upper end, And then the landing pin inserting device 50 is pulled out.

When the body portion 60 is formed into a cross shape, the contact area with the ground is widened to be firmly fixed, and at the same time, rotation can be prevented so that the ground can be stably fixed. The head portion 62 can perform a function of pushing or hitting the landing pin 40 when inserted, and at the same time fixing the eco mat 10. The eccentric portion 64 can be inserted into the ground so that the landing pin 40 is fixed to the ground and the eco mat 10 on the lower side is bound to securely fix the eco mat 10.

The cruciform body portion 60 includes a plurality of locking wedges 66 and a plurality of extending wedges 68 formed at regular intervals along the vertical direction and the locking wedge 66 and the extending wedge 68 Alternately. The locking wedge 66 is formed in the four grooves of a truncated conical body portion 60 having a pointed lower portion and a wedge 68 is formed on the both sides of the body portion 60 in such a manner that a triangular cross- So that the landing pin 40 can be firmly fixed to the ground.

4E, the landing pin 40 includes a pair of vertical holes extending from the head portion 62 to the lower portion of the body portion 60, and a lower end portion of the vertical hole, And an inner pin 70 which is exposed to the outside of the inclined hole through the pair of vertical holes and inclined holes and is fixed to the ground.

In the case of the landing pin 40, it sometimes occurs that the landing pin 40 alone lacks its own supporting force. In this case, when the inner pin 70 is inserted into a pair of through holes and then press-fitted or hitting the inner pin 70 downwardly, the end portion is inserted into the ground by the inclined hole to the side of the body portion 60, The shape of the end of the arrow can be firmly fixed to the ground.
