BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing protective barrier that attenuates and stops the impact energy held by falling objects such as rocks and avalanches.

In order to protect a road, a private house, etc. from falling objects, such as a rockfall and an avalanche, the shock absorption protective barrier for absorbing the impact is provided on the slope. As these protective barriers, horizontally laid protective nets, such as a wire and a gold mesh, are installed between posts spaced apart at predetermined intervals on slopes (Japanese Patent Publication No. 3390132).

However, the conventional shock absorbing protective barrier has the following problems.

<1> Due to the method of absorbing impacts such as falling rocks due to the rigidity of the props and the bending of the protection net, there is a limit to the shocks that can be absorbed, and the construction is enormous in order to construct a protective barrier having greater strength. Cost is needed.

If the distance between the posts is increased, the construction cost is lowered, but the protection net is loosened at the central portion between the posts, and the barrier height is not sufficiently high.

Since the protective net is installed horizontally between the struts, when the land between the struts is a relatively raised ridge, the height of the barrier at the ridge is not sufficiently high.

<4> Since the protective net is installed horizontally between the shores, when the land between the shores is a relatively raised ridge, a gap is generated between the ground and the protective net, and a rockfall or the like passes through the gap. It may be discarded.

<5> In order to solve the problems of the above <3> and <4>, it is necessary to install the props in accordance with the terrain, so that the number of the props increases and the construction cost increases.

When a rockfall or the like collides, the upper and lower sides of the protective net bend to approach the center of the net, thereby reducing the vertical width of the protective net. Therefore, when next rock falls, we may pass over the upper side or the lower side of protection net.

<Examples>

(1) Configuration of the shock absorbing protective barrier

As illustrated in FIG. 1, the shock absorbing protective barrier according to the embodiments of the present invention has a strut 10, a rope member 21, and a net member 22 spaced apart at predetermined intervals, and has a strut 10. The barrier net holding material 30 provided in the direction which terminates the protective net 20, the buffering hole 13 which hold | maintains the rope material 21, and the protective net 20 installed between the ().

Hereinafter, each component is demonstrated in detail.

(2) prop

1 and 2, in the shock absorbing protective barrier according to the first embodiment of the present invention, the support 10 is made of a hardness type, and the plurality of pipe-shaped supports 10 are spaced at predetermined intervals. Placed on the slope (40). In each support 10, the support rope material 11 which fixed the lower part to the slope 40 by the anchor is arrange | positioned, The support rope material 11 is the support rope 10 as shown in FIG. It is held by the strut buffer 12 which grips the strut rope material 11 at the upper end.

The strut buffer 12 has a function of holding the strut rope material 11 and allowing the sliding of the strut rope material 11 to attenuate energy when a tension greater than the frictional resistance of the gripping portion is applied.

If necessary, a ball rope may be connected between each support 10 and the slope 40, or a support buffer opening may be provided at the end or the middle of the ball rope.

(3) protection net

The protection net 20 is a member for receiving a rockfall or the like, and is composed of a rope member 21 installed between the struts 10 and a net member 22 connected to the rope member 21.

As shown in Figs. 1, 4A, and 4B, the rope member 21 is provided between the struts 10 by the end of which is gripped by the buffer port 13.

The mesh member 22 may include a gold mesh or a synthetic resin, and as shown in FIG. 1, the coil member 23 may be wound around the entire length or part of the rope member 21. It may be connected in a movable state.

(4) buffer

The shock absorbing port 13 has a function of holding the rope member 21 and allowing the sliding of the rope member 21 to attenuate energy when a tension equal to or greater than the frictional resistance of the gripping portion is applied.

1 and 4a, the buffer port 13 is formed at the upper and lower ends of the support 10, and functions to connect both members at the intersection of the support 10 and the rope member 21. Can be. On the other hand, as shown in FIG. 4B, the shock absorbing port 13 is disposed between the struts 10 and the struts 10, and the buffer holes 13 are disposed at the polymerization portion of the rope member 21 that is slaughtered from both struts. It may be installed to connect the rope member 21.

A prop buffer port 12 which clamps the buffer port 13 and the support rope material 11, wherein two plates are polymerized so as to sandwich the rope material, and U penetrates the plate body in the polymerized state. A well-known friction-resistant shock absorber, such as clamping a rope material by screwing a nut to a bolt, can be used.

(5) Shock absorption by protective net and prop

When a rockfall or the like collides with the shock absorbing protective barrier including the support post 10 and the protection net 20 described above, the wire rod constituting the net material 22 of the protection net 20 is moved to the sliding and slope downstream. Impact energy is attenuated by the deflection deflection. In addition, the impact energy acting on the protection net 20 also acts on the rope member 21.

The impact energy acts as a tensile force on the rope member 21, and when the tensile force exceeds the gripping force of the shock absorber 13, the rope material 21 slides in the shock absorber 13 in response to the gripping force. The impact energy can be attenuated by the friction force at that time.

Therefore, when holding the rope member 21 by the buffer port 13, as shown in FIG. 1, the remainder part 211 which allows the rope member 21 to slide is possible. Gripping to form).

Impact energy passing through the net material 22, the rope material 21 and the buffer port 13 is finally delivered to the support (10).

When the impact energy acts on the support 10 and exceeds the gripping force of the support buffer 12 formed at the upper end of the support 10, the support rope member 11 slides in the support buffer 12, and the frictional force thereof is increased. The support 10 is inclined while absorbing the brake force against the load.

In addition, when a ball rope is connected to the support 10 or a support buffer is provided on the ball rope, the impact energy may be attenuated by the sliding resistance of the ball rope or the support buffer.

According to the embodiments of the present invention, when the pillar 10 is placed, since the pillar rope 11 is fixed with an anchor instead of using basic concrete, it can be easily placed.

Moreover, since it is a structure which can be easily installed only by installing the upper and lower rope material 21 and the net material 22 between the support | pillars 10, it can be easily constructed at low cost.

In addition, since each of the mesh member 22, the rope member 21, and the support 10 has a function of absorbing impact energy, it is possible to easily construct a shock absorbing protection barrier with high impact energy attenuation efficiency.

(6) barrier height retaining material

The barrier height holding material 30 is a member for preventing the protection net 20 between the support posts 10 from loosening, and is provided along the longitudinal direction of the protection net 20 between the support posts 10.

The barrier height maintaining member 30 may have a length equal to or longer than the length of the strut 10, and may have a pillar shape.

As shown in FIG. 1, the barrier height holding material 30 includes the recessed part 31 formed in order to latch on the rope material 21 near the upper end and the lower end.

The barrier height maintaining member 30 may be formed to include a plurality of bendable portions by forming the joint 32 in at least one location in the longitudinal direction.

As shown in FIG. 5, the barrier height retaining material 30 can be formed to be able to expand and contract, that is, to adjust the length by a method such as forming the slide 34.

The barrier height holding material 30 is latched on and arranged on the rope material 21 formed between the support posts 10.

Since the length of the barrier height retaining material 30 is the same as or longer than the length of the strut 10, it may be installed in the direction of terminating the protective net 20.

The rope member 21 is inserted into the recess 31 near the upper end and near the lower end of the barrier height retaining material 30, and as shown in FIG. In the event of an impact, the barrier height retaining member 30 is easily detached from the rope member 21. In addition, at least a part of the barrier height maintaining material 30 is connected to the net material 22 by a wire 24 or the like.

Since the barrier height holding | maintenance material 30 locks on the rope material 21 of the protection net 20, without placing an anchor etc., it can be easily constructed.

(7) securing barrier height

In the shock absorbing protection barrier formed by installing the protection net 20 between the support posts 10, as shown in FIG. 6A, the protection net 20 loosens toward the valley side at the center between the support posts 10 by weight. When the barrier height becomes H1, the required barrier height H cannot be secured, and a barrier height shortage phenomenon may occur.

However, in the shock absorbing protection barrier according to the embodiments of the present invention, by forming the barrier height retaining material 30 between the struts 10, as shown in FIG. 6B, the barrier height retaining material 30 is protected. By being installed in the longitudinal direction of the net 20, the loosening of the protective net 20 can be prevented and the required barrier height H can be secured.

(8) Securing the barrier height in accordance with the terrain of the slope

When the topography of the slopes 40 between the support posts 10 is elevated, barrier height deficiency may occur at the ridges of the slopes 40.

However, as shown in FIG. 7, the barrier net 20 can be secured even when the terrain is raised by installing the protective net 20 in the direction crossing the barrier height maintaining member 30 provided in the raised portion.

As shown in FIG. 8, when the topography of the slopes 40 between the pillars 10 is recessed, the barrier height retaining material 30 longer than the pillars 10 is disposed to shield the protective net 20. By installing the height retaining material 30 in a direction crossing the gap, the gap A generated when the barrier height retaining material 30 is not used can be prevented, so that falling rocks and the like can pass through the gap A. have. In this case, anchor pins 35 are formed in the lower portion of the barrier height retaining member 30 and the barrier height retaining member 30 is fixed to the slope 40 to facilitate the installation of the protective net 20 in the gap A. I can do it.

The barrier height maintaining member 30 according to the embodiments of the present invention may have a high construction efficiency because the length can be adjusted in the field according to the topography of the slope 40.

(9) Shock absorption effect by barrier height holding material

As illustrated in FIG. 9, when rockfall or the like collides with the shock absorbing protection barrier according to the embodiments of the present invention, the rockfall or the like is returned by the weight of the barrier height retaining member 30 held by the protection net 20. Brake force acts. The impact energy is attenuated, or absorbed, by the brake force, thereby weakening the impact force acting on the protective net 20 or the support 10.

In addition, since the barrier height retaining material 30 is disposed on the mountain side rather than the valley side of the protective net 20, a rockfall or the like directly collides with the barrier height retaining material 30, so that most of the impact is applied to the barrier height maintaining material. Since 30 is taken in, the risk of damaging the protective net 20 by an impact is reduced.

Since the barrier height retaining material 30 is only connected to the rope material 21 and connected to the mesh material 22 with a wire 24 or the like, the barrier height retaining material 30 is not limited to the shock absorbing performance of the shock absorbing protective barrier even when damaged by an impact. It is also easy and inexpensive to replace the barrier height holding material 30 without affecting.

On the other hand, the barrier height maintaining material 30 gives weight to the protection net 20. The barrier height retaining material 30 also moves along with the sliding of the rope material 21 included in the protection net 20 or the movement of the net material 22, and the weight given to the protection net 20 is applied to the impact. Since it acts as a brake force, the shock absorbing performance of the shock absorbing protective barrier is enhanced.

The barrier height holding material 30 is held by the rope material 21, and is provided in a structure that is detached when impacted by a rockfall or the like. When the barrier height holding member 30 is separated, the impact energy is absorbed by resisting the resistance by the pin 33 or the like. By the barrier height retaining material 30 is separated, the sliding of the rope material 21 is not restrained and the absorption effect of the impact energy is not disturbed. In addition, since the barrier height maintaining member 30 is connected to the mesh member 22 by a wire 24 or the like, the weight acts as a brake force against impact while being given to the mesh member 22. However, it does not affect the shock absorption performance of the shock absorption protection barrier.

The barrier height retaining material 30 forms the joint 32 in at least one location in the longitudinal direction, and when the impact is caused by falling rocks or the like, as shown in FIG. ) May be bent.

Since the joint 32 is pulled out against the frictional force, the joint 32 absorbs the impact energy when it is pulled out.

In addition, since the barrier height retaining material 30 is bent to wrap the rock, the rock fall can be prevented from falling from the protective net 20.

(10) the formation of an extension

When the barrier height holding member 30 having a length longer than that of the pillar 10 is used, the rope member 21 is installed in the entire length of the barrier height holding member 30, and as shown in FIG. Expansion portion (B) may be formed on the upper side outward from the line connecting the top of the). By forming the expansion portion B, it is possible to increase the water hammer area that receives the falling rocks, as compared with the case where the protective net 20 is horizontally installed between the pillars 10.

In addition, since the water hammer area is enlarged, the vertical width of the protection net 20 is ensured even after the protection net 20 is bent and deformed due to falling rocks, and the like. The case of passing through the upper side or the lower side can be reduced.

By providing a plurality of barrier height holding | maintenance materials 30, the shape of the extended part B to form can be changed.

(11) Other Examples

In the above-described embodiments, the barrier height maintaining member 30 is connected to the shock absorbing protective barrier made of the rope member 21 and the net member 22, but the plurality of wire ropes formed between the posts are protected by the protective net. Alternatively, the same effect can be obtained by applying the above-described barrier height retaining material 30 to the shock absorbing protective barrier formed by only installing the gold mesh as the protective net.
