Abstract

In order to alleviate the slope of the river and maintain the end and the cross-sectional shape of the river, by using the ridges, a drop hole that is installed across the river can be used to prevent the erosion of the river, as well as to quickly record the river and provide a habitat for aquatic life. The eco-drop construction method using nature-friendly sedan end is disclosed. The present invention, the step of using a tree branch without a blind eye, the outside using a tree branch with a blind force to produce a cut end of 40cm ~ 60cm in diameter; Gently inclining the bed ground of the bed falling hole; Preventing natural erosion by stacking natural stones on the upstream and downstream of the freefall hole and on both sides of the freefall hole; Driving a plurality of wooden piles so as to be perpendicular to the direction of the reservoir at intervals of 40 cm to 60 cm from the downstream of the drop hole to the upstream of the drop hole, which is gently tilted in the step; And arranging the upper end of the wooden pile so as to intersect with the direction of water flow so that the upper end is fixed between the wooden piles. By forming a drop hole with a wooden end made of a natural material having life force, erosion of the river Prevention, as well as rapid recording of the banks, provides aquatic habitat.

Description

Method for constructing ecological water-fall using a brushwood}

The present invention relates to an ecological drop hole construction method using the bottom end, and in particular, to reduce the slope of the river in the stream and to maintain the end and the cross-sectional shape of the river by using the end of the downhole erosion of the river by forming the drop hole It also relates to the method of ecological drop construction using nature-friendly cutting stages, such as prevention, rapid greening of river banks, and providing habitat for aquatic organisms.

In general, the river bed maintenance hole in the river structure refers to the structure that is installed across the river to relax the river slope and maintain the end and cross-sectional shape of the river. In the riverbed maintenance, there is a drop, which is called a drop. Generally, the drop is made of a concrete structure or a concrete block structure. The free fall hole made of concrete is excellent in the stability of the riverbed, but is not suitable for the recent natural river formation method.

In other words, the free fall hole using the concrete material has a problem that it is difficult to restore the natural river because it does not only damage the aesthetics of the natural river as a material selected in consideration of functional aspects, but also does not provide a suitable environment as a habitat for aquatic life.

The present invention has been invented to solve the above problems, by using a natural material with vitality, that is, by using a chopped end made of a sprouted tree branches by forming a drop hole, to prevent the erosion of the lower eye, by recording the lower eye quickly The purpose is to provide a method for the construction of ecological drop holes using a natural-friendly cutting edge that provides a habitat for aquatic organisms.

The present invention for performing the above object,

Iii) using a tree branch with no budding power inside, and using a tree branch with budding power outside to produce a chopped end having a diameter of 40 cm to 60 cm; ii) gentle slope of the riverbed of the riverbed drop (B) stacking natural stones on the upstream of the freefall hole and downstream of the freefall hole and on both sides of the freefall hole to prevent erosion of the river; Driving a plurality of wooden piles so as to be perpendicular to the direction of the reservoir at intervals of 40 cm to 60 cm upstream to the bottom of the ground; And iii) spreading the chopped end to intersect with the direction of water flow in the upper part of the wooden pile so that the chopped end is fixed between the wooden piles.

By creating a free drop ball made of natural materials with vitality, it not only prevents the erosion of rivers, but also rapidly records rivers and provides habitat for aquatic organisms.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a front view for showing the configuration of the tip used in the ecological drop hole composition method using the tip according to the present invention, Figure 2 is a cross-sectional view of the river is applied ecological drop hole composition method using the tip end according to the present invention 3 is a plan view of a river to which an ecological drop hole composition method using the tip of the present invention is applied.

Ecological drop hole composition according to the present invention is possible during the year except the rainy season, winter season. First, referring to Figure 1, using a vital material, that is, branches with a blindness 2cm, 1m or more in length and a material without vitality, that is, without a blindness, 2cm in diameter, 1m or more in length the branches ( 110). The outer end of the upper end 110 is a branch with a blinding power, the inner end of the lower end is made of a tree branch without the blinding power, and then a cylindrical bundle is made and a rope 112 having a diameter of 8 mm or more so that the diameter is about 40 cm to 60 cm. Make a round shape using. When the flow rate of the river is fast, the outside of the tip 110 is tightly tied together with the rope 112 using a wire of 2 mm or more in diameter.

Here, the branches forming the tip 110 should be tied very tightly in a twisted state. This is because if the empty space is generated in the tip 110, the shock 110 may cause physical shock to the tip 110 due to the rush of water. The length of the bottom end 110 may vary depending on the width of the river.

When the bottom end 110 is completed, the bottom ground ground 120 of the dropping hole 130 where the end 110 is placed is adjusted so that the height / length is within 1/20. When the inclination of the lower ground ground 120 is adjusted, natural stones are stacked on both sides 136 of the upstream 132 of the free fall hole 130 and the downstream 134 of the free fall hole 130 and the free fall hole 130 to prevent erosion of the river.

When the lower ground ground 120 is gently adjusted, as shown in FIGS. 2 and 3, a plurality of wooden piles 140 are driven at intervals of 40 cm to 60 cm to be perpendicular to the direction of the reservoir from the downstream 134 of the drop hole. . Lay the end 110 on the top of the wood pile 140 so that the end 110 is fixed between the wood pile 140. At this time, the end 110 is installed to cross the river.

That is, as shown in Figure 3 from the downstream 133 of the free fall hole to the upstream 132 of the free fall hole 130 to the wooden pile 140 at intervals of 40 cm to 60 cm and the upper end of the wooden pile 140 ( By fixing 110, the end 110 is arranged in multiple stages so as to intersect with the direction in which water flows. In addition, if necessary, a portion of the free fall hole 130 may be provided with a predetermined portion of the empty space to form a fish can move.

Thus, the ecological drop construction method using the chopped end according to the present invention is used to prevent the erosion of the riverbed and riverbanks and to maintain the shape of the stream without using a material such as concrete, reinforcement chopped end (110) It is economical by use. In addition, the flexible branches constituting the tip 110 reduce the flow velocity of the stream and at the same time reduce the traction to accelerate the deposition and protect the riverbed and riverbed from erosion, and maintain the shape of the river.

In addition, as time goes by, the tree branches that grow outwardly of the ridge end 110 provide a habitat for aquatic creatures, and because the free fall hole 130 is formed with a gentle slope, the passage of fish is blocked. To prevent. Therefore, it is possible to record the river bank quickly and to use it as a habitat for fish, thus providing a natural friendly drop hole.

As described above, the present invention has the effect of creating a stream naturally by providing a space for aquatic organisms by quickly recording a river and providing a habitat for aquatic organisms by creating a drop hole using a tree bed using natural materials having vitality such as tree branches.

Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited thereto and may be improved or modified by those skilled in the art within the scope of the technical idea of the present invention.
