The present invention relates to a rockfall prevention fence for preventing the falling of the falling rock on the road by installing in the cutout of the roadside, and more particularly, it is easy to remove the rockfall during the occurrence of rockfall and can quickly handle the falling rockfall traffic communication It can be smoothly in a short time, and particularly relates to an open-type rockfall prevention fence that can be easily replaced and repaired broken parts generated during rockfall can reduce maintenance costs.

In general, the mountains of Korea are prone to long-term erosion and weathering.

Sloped hills on roadsides, which are not usually well-planned for landscaping, have often caused unjust damage to vehicles or people passing by stones or soil due to flooding or wind damage.

In order to solve this problem, conventionally, rockfalls have been prevented by interlacing ropes and the like, but this is only a primitive one-sided solution, and rocks cannot be supported for a long time. Because it always contains anxiety factors,

Not only do they consciously risk the vehicles or people who pass along these roads of Yasan, but they also have defects that are not aesthetically pleasing.

When a road or building is built along a hill or ridge, a portion of the ground is cut, which results in a constant slope.

Since the inclined surface is artificially formed, its surface may be unstable and easily collapsed by rainwater and sea ice, or part of the rock wall may fall off and fall.

Therefore, when these rocks fall on a driving vehicle or a building in which a person resides, a great deal of human and material damage occurs.

Thus, by using a method such as covering the inclined surface with a rake block or installing a structure for forming a vegetation zone, to prevent the falling of rockfall and soil.

However, these methods directly cover the surface of the inclined surface to prevent the falling of the falling rocks and soil itself, and may not be applicable as described above depending on the environment or the characteristics of the inclined surface.

One example is an inclined surface made of rock walls or a slope formed with a vegetation zone.

Therefore, in these areas, rockfall protection nets are installed between roads or buildings and slopes to block falling or falling soils, thereby protecting the driving vehicle or buildings and those residing in them. .

On the other hand, as a way to prevent such falling rocks are installed on the roadside rockfall prevention fences, these rockfall prevention fences are effective to block the inflow of relatively small rockfall.

The conventional rockfall prevention fence is formed of a structure in which the wire extending in the transverse direction between the beam is installed upright to be fixed to the retaining wall spaced apart at regular intervals and arranged up and down, the fence net is installed at the height of the beam.

However, in the case of the conventional rockfall prevention fence has to deal with the form of transporting the rockfall by bypassing the fence when the rockfall occurs, it takes a lot of time and labor for the treatment of rockfall has the disadvantage of inconvenient work.

In order to avoid this inconvenience, it is necessary to partially remove the broken fence net in the area where the rockfall has fallen and to re-install the fence net after the rockfall has been processed. Therefore, the maintenance cost of the rockfall prevention fence and the cost of the rockfall treatment are excessive. There is a problem.

In addition, if the wire and fence nets are largely damaged due to rockfall, partial repair of the broken wires and fence nets is impossible. Therefore, it is necessary to replace all of the wires and fence nets in a certain period. It also takes a long time to repair, and this causes a problem that causes a long delay or interruption of traffic on the road.

On the other hand, in order to check the rockfall prevention fence before the rockfall occurrence factors such as heavy rain, there is a lot of inconvenience related to the worker movement because the fence must be bypassed and inspected.

In order to solve such inconveniences, Korean Registered Utility Model Publication No. 20-0387107, Registration No. 20-0425368 provide a method for handling rockfall through the installation of a door that can be opened and closed on a part of the rockfall prevention fence.

This method can solve the inconvenience of bypassing the fence to some extent, but the structure of the structure is complicated by the structure of rotating and opening the door through one hinge part and locking the door through the other locking part. There are a lot of parts and the manufacturing cost is high and the production is difficult, and the installation workability is inferior. Above all, if the door itself is damaged or distorted due to a large rockfall, the door cannot be opened normally. There are costs and work inefficiencies, such as the need to remove them.

Therefore, the present invention has been devised in view of the above, by implementing a new type of removable opening and closing door that can be easily fixed or easily removed by hanging on the rockfall prevention fence to prevent falling of the incision on the road, Opening and closing doors can be easily opened in case of falling rocks, and it is possible to deal with falling rocks quickly and solve the inconvenience of having to check the fence by checking fences. It is an object of the present invention to provide an open and close rockfall-resistant fence that can be easily replaced and repaired, which can greatly reduce maintenance costs.

The present invention for achieving the above object is a beam that is installed upright fixed to the retaining wall and the bottom, the wires are spaced up and down spaced at regular intervals while extending laterally between the beams, fences installed at the height of the beam In the rockfall prevention fence including a net, the lower part of the fence (area) is replaced by an opening and closing door that can be opened and closed, and the opening and closing door is sandwiched between the fixing parts of both beams by wire ropes and fixing pins provided at both ends. Characterized in that the form can be hooked or pulled out.

In addition, the opening and closing door is a square opening and closing door frame, the fence net covering the opening and closing door frame, and the wire rope and fixing pins which are integrally fixed while being spaced apart at regular intervals while extending the opening and closing door frame in the horizontal direction. Characterized in that it comprises a.

In addition, the fixing part is characterized in that the two c-bracket is formed in a structure that is integrally fixed to the beam while being combined facing each other in the form of closing both openings of the beam.

In addition, the c-bracket is characterized in that it comprises a reinforcing piece protruding in the middle of the inner surface to prevent the flow of the self-reinforcement and wire rope and fixing pins.

In addition, the wire rope and the fixing pin is composed of a pin member having a hook of the front end and a hook of the rear end and a rope member that is tied to a predetermined length by two lines after the hook of the pin member is integrally connected. It is characterized by.

Hereinafter, with reference to the accompanying drawings will be described in detail the open-type rockfall-resistant fence according to an embodiment of the present invention.

As shown in Figures 1 to 4, the lower base concrete retaining wall of the incision surface is vertically installed at a certain distance the beam 10 of the bent form at a certain distance, and the horizontal direction between the beams 10 so installed The wires 11 extending to each other are spaced apart at regular intervals and disposed up and down, and a fence net 12 is installed at a beam height on the front surface of the beam 10.

At this time, the wire 11 is installed in a form in which the middle part of the length is supported by the U-bolt 20 in the beam 10 and fixed in a welding or fastening structure at both ends, the wire 11 and The fence nets 12 are bound to each other in a known manner.

In the rockfall prevention fence formed of such a structure, at least two sections between the lower portion of the fence, for example, the beam 10 and the beam 10, are replaced with an opening / closing door 13 that can be opened and closed.

That is, the opening and closing door 13 for opening a fence in the event of rockfall is provided in at least two places.

The body of the opening and closing door 13 has a rectangular opening and closing door frame 17 having a left and right length corresponding to the distance between the beams 10 and the vertical height of the operator can enter, that is, the horizontal member and the vertical member rectangular frame Consists of a door frame 17 of the form weave together, the door frame 17 is covered with a fence net 12 over the entire area is finished.

At this time, the door frame 17 and the fence net 12 may be bound in a known manner.

In order to install and dismantle the opening and closing door 13, the opening and closing door frame 17 is integrally provided with a wire rope 14 and a fixing pin 15 which are spaced apart at regular intervals while extending the opening and closing door frame 17 laterally. Equation is provided.

That is, at least two or more wire ropes 14 having fixing pins 15 at both ends are disposed horizontally across the door frame 17, and a portion where the wire rope 14 and the door frame 17 cross each other. Since a plurality of places are tied together by the PVC-coated iron wire 21, the door frame 17 and the wire rope 14 and the fixing pin 15 can be integrally configured.

Accordingly, in the case of installing or dismantling the opening and closing door 13, the opening and closing door 13 is easily installed in such a manner that the fixing pins 15 on both sides are inserted onto the fixing part 16 on the side of the beam 10 to be hooked or removed. Can be dismantled.

That is, when the rockfall occurs, the opening and closing door 13 can be easily opened and the rockfall can be treated, and the opening and closing door 13 can be easily closed even after the rockfall treatment.

Here, the wire rope 14 and the fixing pin 15 is made of a form that is integrally connected by a conventional clip or the like.

For example, one end portion of the rope member is inserted into the rear end ring of the pin member having the hook of the front end and the rear end of the rope member, and may be formed in a form in which a predetermined length is bound in two lines by a clip or the like while being overlapped again.

Thus, as the wire rope 14 and the fixing pin 15 is configured and integrally bound to the wire rope 14 or the opening / closing door frame 17, the opening / closing door 13 is formed with fixing pins 15 on both sides. In this case, the fixing pin 15 may be installed or dismantled.

The fixing part 16 is provided on the beam 10 side for the installation of the opening and closing door 13, and the fixing part 16 has a form in which the c-bracket 18 is combined on the beam 10 side.

For example, the two c-brackets may be configured to be integrally fixed by bolting or welding to the beam while being combined to face each other in the form of closing both openings of the H-beam.

Accordingly, the opening and closing door 13 is installed between the beam 10 in the form of hanging or pulling the wire rope 14 and the fixing pin 15 into the space formed between the c-bracket 18 and the beam 10. It can be dismantled.

At this time, the c-bracket 18 has a reinforcing piece 19 protrudingly formed in the middle of the inner surface, thereby reinforcing the rigidity of the bracket itself, and preventing severe flow of the wire rope 14 and the fixing pin 15. You can do it.

Therefore, if a rockfall occurs due to heavy rain, ground weakness, natural weathering, etc., the worker can simply remove the wire rope 14 and the fixing pin 15 on both sides of the opening / closing door 13 from the fixing part 16. Since the opening and closing door 13 can be easily dismantled to open the fence, the rockfall treatment can be performed very simply and quickly.

On the other hand, due to the large amount of rockfall, the opening and closing door 13 may be difficult to pull out the wire rope 14 and the fixing pin 15 from the fixing portion 16 in a tense state. By releasing the iron wire 21 that binds the opening and closing door 13 and the wire rope 14 to separate the opening and closing door 13 and the wire rope 14, the opening and closing door 13 can be easily removed.

In addition, after all the rock-fall treatments are completed, the wire rope 14 and the fixing pins 15 on both sides are held on the fixing part 16 in the beam 10 even when the door 13 is installed again. Since it is fitted, opening and closing door installation can be very easy.

On the other hand, even if the door is damaged due to falling rocks and need to be replaced, the door can be manufactured simply by using the frame and fixing means (wire rope and fixing pin) that have a net, so it can be replaced at a low cost. The associated costs can be reduced.
