Description

Combined type four-way dam {COMBINATION TYPE EROSION CONTROL DAM}

The present design (Disclosure) relates to a combined type all-round dam, and more particularly, to a combined-type all-round dam capable of simultaneously performing the functions of a buttress four-way dam and a slit four-way dam.

Here, the background technology related to the present invention is provided, and these do not necessarily mean the known technology (This section provides background information related to the present disclosure which is not necessarily prior art).

In general, Sabang Dam is a transmission-type dam structure that is installed in a valley where there is a risk of a landslide or a river with severe loss of driftwood and rocks to capture soil and driftwood and reduce the flow rate to pass through it to prevent erosion at the foot of the mountain, prevent low sand damage, and prevent sediment. And prevent flooding.

In order to prevent soil and wood from floating upstream, the four-sided dam having such a function places the dam side (dam shoulder) on both sides of the dam base and the dam base, respectively, and blocks the timber floating from the upstream between the dam sides. And install a transmissive blocking part to let water flow out.

The structure of the transmissive cut-off part is different according to the buttress four-way dam disclosed in Korean Patent Registration No. 491444 and the slit four-way dam disclosed in Korean Patent Registration No. 890836.

In other words, the transmissive cut-off part applied to the buttress four-way dam disclosed in Korean Patent Registration No. 491444 is fixedly installed at the base of the dam with a plurality of steel pipes or vertical members made of H-beams at intervals, and the vertical members are spaced horizontally. And the screen part is installed.

Further, the vertical members are each supported by a buttless member provided on the downstream side.

In addition, the slit four-way dam of Korean Patent Registration No. 890836 includes a plurality of vertical members installed in the transverse direction of the steel without a separate screen, and a binding member that interconnects and binds the upper ends of the vertical members.

As a result, the buttress four-sided dam is a dam that transmits the force generated by running water to the foundation ground using the buttress, and the slit four-sided dam is constructed of reinforced concrete or cylindrical steel columns in the shape of a comb to prevent driftwood or sedimentary power during flooding. , It has a structure that slowly flows down the soil in normal times.

The Buttress Sabang Dam is installed in a mooring where driftwood or soil is expected to move, and structurally, it is mainly installed in a place where the width of the dam site is wide and the height of the dam is low, and the Slit Sabang Dam is a Sabang Dam constructed for the purpose of blocking only driftwood or some stone power. It is installed in a mooring where driftwood is expected to occur or where there is a lot of huge stone power and can be easily dropped by running water.

As described above, in the conventional four-way dams, buttless four-sided dams or slit four-sided dams are separately installed according to the location and flow type, and this caused an increase in installation cost and time.

The plurality of upstream vertical members 121 are arranged in a row in a direction that connects the dam shoulders 113, that is, in a direction substantially orthogonal to the flowing water direction, and are arranged to have a set first interval.

In addition, the plurality of upstream vertical members 121 has a lower end fixed to the dam base 111.

Next, the plurality of downstream vertical members 131 are disposed downstream of the plurality of upstream vertical members 121, and are disposed apart by a second interval set in the direction connecting the dam shoulders 113, and the direction of flowing water It is disposed to be alternately with a plurality of upstream vertical members 121.

That is, in the composite four-way dam 100 according to the present disclosure, the upstream vertical member 121 and the downstream vertical member 131 are arranged in a W shape of a triangular structure by a double crosswise arrangement, and a plurality of upstream horizontal members to be described later (123), by combining the plurality of downstream horizontal members 133 and the reinforcing member 140, it is possible to simultaneously perform the functions of the buttress four-way dam and the slit four-way dam.

More precisely, the complex-type four-way dam 100 according to the present disclosure mainly functions as a slit four-sided dam, but can exert the function of a buttless four-sided dam.

To this end, it is preferable that the number of the plurality of upstream vertical members 121 is provided one greater than the number of the plurality of downstream vertical members 131.

In addition, it is preferable that the first interval and the second interval are provided equally. Unlike this, it goes without saying that the first and second intervals can be adjusted in consideration of the difference in speed between the center and the periphery of the river.

In addition, it is preferable that the plurality of upstream vertical members 121 and the plurality of downstream vertical members 131 are made of H-beam steel. In this case, it goes without saying that the H beams are arranged so that the height (H) direction of the H beam coincides with the direction of the flowing water so that the bending stiffness due to the flowing water is maximized.

On the other hand, the plurality of downstream vertical members 131, like the plurality of upstream vertical members 121, the lower end is fixed to the dam base, a plurality of upstream vertical members 121 and a plurality of downstream vertical members 131 It is preferable that it is provided to be fixed by screwing with an anchor member buried to be exposed to the dam base 111.

To this end, the dam base 111 has a bolt-shaped anchor member 151 to which a plurality of upstream vertical members 121 and a plurality of downstream vertical members 131 are coupled is embedded in concrete, and a plurality of upstream vertical members ( 121) and the plurality of downstream vertical members 131 are preferably provided with a base plate 153 having a coupling hole 153a fastened to the anchor member 151 at the bottom, respectively.

Next, the plurality of upstream horizontal members 123 connect the plurality of upstream vertical members 121 in the horizontal direction, that is, in the direction in which the dam shoulders 113 are connected, and the length of the plurality of upstream vertical members 121 They are arranged apart with a third interval set in the direction.

Next, the plurality of downstream horizontal members 133 connect the plurality of downstream vertical members 131 in the horizontal direction, and are disposed apart by a fourth interval set in the longitudinal direction of the plurality of downstream vertical members 131.

Here, it is preferable that the plurality of downstream horizontal members 133 are disposed to be staggered in the vertical direction with the plurality of upstream horizontal members 123.

This is a plurality of downstream transverse members 133 or a plurality of downstream transverse members 133 or a plurality of downstream longitudinal members in the flow direction of driftwood, megalithic power or soil passing through a space formed by a plurality of upstream vertical members 121 and a plurality of upstream transverse members 123. By providing the member 131, it is to obtain a double buffering action or a double blocking action.

In addition, it is preferable that the 3rd interval and the 4th interval are provided equally.

In contrast, in consideration of the difference between the upper and lower speeds of the running water, the vertical gap between the plurality of upstream horizontal members 123 and the plurality of downstream horizontal members 133 increases as the distance from the dam base 111 increases. It can be provided so as to be lost.

Meanwhile, the plurality of upstream horizontal members 123 and the plurality of downstream horizontal members 133 may be provided with a rectangular steel or concrete rod.

In addition, in the present embodiment, the plurality of upstream horizontal members 123 and the plurality of downstream horizontal members 133 are, respectively, a plurality of upstream vertical members in the direction of running water for blocking (or reducing the speed) of driftwood and preventing soil sand. 121) and the plurality of downstream vertical members 131 is preferably fixed to the front surface.

Next, the reinforcing member 140 connects adjacent ones of the plurality of upstream vertical members 121 and the plurality of downstream vertical members 131 to each other in the horizontal direction.

Here, the reinforcing member 140 connects the adjacent upstream vertical members 121 and the downstream vertical members 131 in a state not aligned with the adjacent reinforcing members.

This forms a triangular structure, and supports the load and impact force caused by driftwood, megalithic power, and soil.

FIG. 5 is a side view of a combined four-sided dam according to another embodiment of the present invention, and FIG. 6 is a side-viewed view of a combined four-sided dam according to another embodiment to which a depression is applied in FIG. 5.

If the flow rate increases rapidly, a giant earth or rock may directly collide with the upstream vertical member 121 and the upstream horizontal member 123. The load applied to one upstream vertical member 121 is distributed by two reinforcing members 140 to the two downstream vertical members 131.

Therefore, when the kinetic energy of a giant earth or rock is large, a plurality of reinforcing members 140 capable of supporting a large load are required.

Referring to FIG. 5, the composite four-way dam according to the present embodiment includes a plurality of screen members 150 disposed at the lower ends of the plurality of downstream vertical members.

The screen member 150 forms the jersey soils 1 and 2. The soil stone blocked by the screen member 150 has an effect of reducing the flow velocity and dispersing the impact force of the giant soil stone or rock into the plurality of upstream vertical members 121 and the plurality of downstream vertical members 131.

Specifically, at the beginning of the occurrence of a flood caused by rainfall, soils with a small particle size are introduced and are blocked by the downstream vertical members 131 to form the downstream soiled rocks 1. When the flow rate increases and the flow rate increases, the soil stone having a larger particle size is blocked by the dam base 111 and the upstream horizontal member 123 to form the upstream blocked soil stone 2.

When the flow rate increases and a large amount of sediment flow occurs, a large sediment or rock collides with the dam. At this time, it first collides with the upstream deterred soil 2. The impact force caused by the giant earth or rock due to the primary impact is dispersed to the downstream side by a large number of individual earth stones constituting the upstream deterrent earth 2.

That is, the moving speed of the giant earth or rock is reduced by the first collision, and the impact force according to the reduced speed is distributed over a wide range. The distributed impact force is injected to the plurality of upstream vertical members 121.

In addition, the downstream deterred earth stone 1 allows the impact force of the giant earth and rock applied to the upstream lowered earth stone 2 to be evenly distributed to the plurality of downstream vertical members 131.

Accordingly, the composite dam according to FIG. 5 distributes the impact force of one giant earth or rock to a plurality of upstream vertical members 121 and a plurality of downstream vertical members 131.

The giant earth and rock first collided with the upstream low-lying earth and stone 2 collide with the upstream vertical member 121 or the upstream horizontal member 123 at a slow speed. The impact force at this time is significantly reduced compared to the impact force caused by the primary impact.

That is, the construction of the reinforcing material 140 is simplified, and damage to the entire complex four-way dam according to the present invention can be minimized.

In addition, in the complex four-way dam according to the present embodiment, the plurality of screen members 150 are coupled to the plurality of downstream vertical members 131 so as to be detachable, and a plurality of adjacent vertical members 150 in the longitudinal direction The spacing between the screen members 150 of the can be adjusted.

By adjusting the spacing between the screen members 150, it is possible to form a low-lying soil stone (1, 2) suitable for the terrain in which the complex four-way dam according to the present invention is installed.

Referring to FIG. 6, in the complex four-way dam according to the present embodiment, the dam base 111 is a recessed portion 112 that is recessed downward between a plurality of upstream vertical members 121 and a plurality of downstream vertical members 131 ).

In the recessed part 112, a part of the downstream deterred soil 1 flowing in first is buried. The downstream deterrent soil 1 buried in the depression 1120 has an effect of distributing the impact force of the giant soil and rocks obliquely to the lower side of the dam base 111.

The impact force is not only applied to the dam base 111 itself, but is also applied in the downward direction of the base.

When the impact force of the giant earth and rock is directly generated on the upstream vertical member 121, it is transmitted to the dam base 111 through the anchor member 151. However, at this time, an impact force is applied locally to the dam base 111 in contact with the anchor member 151, thereby increasing the possibility of damage to the dam base 111.

In the composite four-way dam according to FIG. 6, impact forces may be distributed to all of the plurality of upstream vertical members 121, the plurality of downstream vertical members 131, and the dam base 111.

In addition, the recessed portion 112 is preferably formed to be inclined upstream and downstream. In the inclined recessed portion 112, in particular, since the impact force by the downstream deterrent soil 1 is applied at a large angle, the impact force can be dispersed in a wide range.

When the depression 112 is formed vertically, the impact force is concentrated to the angled portion of the depression 1120, so that the fatigue of the corresponding portion is accumulated, and eventually the possibility of breakage increases.

In addition, it is possible to provide an eco-friendly function because the movement of wild animals is free by using a gentle slope structure.

On the other hand, when an actual flood occurs, the topography may be changed by a sediment flow or a sediment flow. In addition, there is a problem that prediction is very difficult as a result of the terrain or the above-described transformation of the terrain of the soil and the soil.

Therefore, it may be difficult to predict the shape and structure of a suitable stone filling during construction, or a large design cost may occur.

However, in the composite dam according to FIGS. 5 to 6, the low-lying soils 1 and 2 are naturally formed at the beginning of the flood. There is an advantage that an additional stone filling process is unnecessary during construction.

In addition, the structure of the low-lying soil (1, 2), which is most effective in distributing impact force, can be formed naturally.
