Description

TECHNICAL FIELD [0001] The present invention relates to a prefabricated ecological moving bridge using a bending type girder,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ecological moving bridge, and more particularly, to a prefabricated ecological moving bridge using a bending type girder which is convenient to construct using a prefabricated girder,

In general, an eco-bridge (hereinafter referred to as "eco-bridge") refers to a passage through which an animal can move, and the habitat of wild animals and plants is cut off due to construction of roads, dams, It is a manmade structure that is installed to mitigate damage or destruction and to help move wild animals.

This is the first time the need has been raised by French hunters who have found that the new roads are built to reduce the hunting of nearby forests, and the importance of environmental destruction and environmental conservation has increased in recent years. More and more.

Domestic ecosystems are accelerating the rate of environmental destruction due to indiscriminate development of poaching, overfishing, or environmental pollution. As one of the causes of environmental destruction, 'roads' not only destroy wildlife habitats but also habitat It is perceived as a dangerous factor that can adversely affect the ecosystem.

However, considering that 'road' is a necessary tool for human activities, 'road' should not be left to be recognized as a main cause of environmental destruction. In the present invention, 'road' We have reviewed the problems of existing eco-bridge and proposed improvements. In order to compensate for the negative aspect of 'road' in terms of environment.

In other words, the 'road' is the scale of the ecosystem by various development activities such as the development of sports facilities, residential land development, industrial complex, and the threat of livelihood of living things due to noise of traffic noise and night light, Of course, the ecosystem is further fragmented.

Conventional eco-bridges developed with these problems are usually constructed in the form of tunnel-type bridges and general bridges in the demilitarized zone or mountainous area, with the average width of the moving passages being 4.8 m. However, the conventional eco bridge has a limitation in that it can not be enlarged due to its high construction cost, and it can not sufficiently block the noise, vibration and light caused by the incidental construction of various traffic facilities, And an environment suitable for habitat is not provided.

In other words, there is a problem that the animal does not actually pass through, and rather, an accident that an animal passes through the road and strikes the car frequently occurs.

An example for solving such a problem has been disclosed in Korean Patent Application No. 10-2003-0034775, " Environmentally friendly ecological connection channel ".

The prior art is directed to an eco-friendly ecological connection passage, which aims at providing a friendly ecological connection passage for reducing environmental burden and realizing smooth movement of animals.

This prior art ecological connection passage includes a steel structure in which a steel box is used as a basic frame for a bridge and a concrete plant plant box is formed on the steel roof as a foundation and a lightweight type foamed ceramic- Artificial soil; Vegetation plants planted on top of the artificial soil; A triple soundproof wall composed of a cerasol formed of a high density porous lightweight soil and natural bamboo and wood to be installed at both sides of the plant box to block noise and light due to traffic; And a bio-board composed of porous ceramics and sand having a large particle size and attached to the outer wall of the steel structure.

Therefore, according to the prior art, an environment in which animals can actually move is created, thereby minimizing environmental destruction caused by roads, sustaining the ecosystem of plants and animals, and reducing the cost of construction.

On the other hand, there has been a discussion about a construction method that can reduce air and reduce manufacturing cost by simplifying the construction of the ecological moving bridge. In order to shorten the air, methods for reducing the curing period in the field or omitting the curing process should be sought.

FIG. 1 is a sectional view of a girder block of a prefabricated ecological moving bridge using a bending type girder according to an embodiment of the present invention, FIG. 2 is a sectional view and a connecting block of the combined type girder, FIG. 4 is a view showing another embodiment of the connection block. FIG.

1 to 4, the ecological moving bridge 10 of the present invention may be constituted to include a bridge pier 400, a girder 100, and a drain 200.

The bridge pier 400 is a component that is installed in an artificial facility 20 such as a road and provides support force while supporting the ecological moving bridge 10.

The bridge pier 400 generally is made of reinforced concrete and plays a role corresponding to the tensile force and compressive force applied to the bridge pier 400. Particularly, since the bridge pier 400 is concentratedly applied with compressive force, the cross-sectional area can be increased.

The girder 100 is a component that substantially performs the function of the ecological moving bridge 10.

The girder 100 is installed on the upper part of the bridge pier 400 and is installed in a form crossing the artificial facility 20. A ground layer is laid along the upper surface to provide a planting space where plants are planted, It is a kind of reinforced concrete structure.

The girder (100) is usually made of an I-shaped or box-shaped cross-section so that its own weight is reduced, and it is designed to resist three-dimensionally against bending, twisting, and horizontal loads.

The method of constructing the girder (100) can be constructed in the field or in a factory, then assembled in the field, or combined with the above two advantages.

 The girder 100 of the present invention may be a constitution of the girder block 300, the connecting block 500 and the connecting material 310.

The girder block 300 includes a wall 120 and a lower plate 110 disposed at an upper portion of the bridge pier 400 to form a part of the planting space and a pair of . ≪ / RTI >

The lower plate 110 is installed at the upper part of the bridge pier 400 and is constructed with a predetermined width to form a rod. The lower plate 110 may be made of reinforced concrete to receive and offset the load imposed on the rod or to transfer the load to the bridge pier 400 to disperse the load.

The wall 120 is made of reinforced concrete, and it prevents soil or gravel in the cover layer from being lost to the outside of the girder 100, thereby providing a stable planting space for the plants.

The cover layer provides gravel on the lower part and the soil on the upper part to provide the planting space of the plants as well as the moving rod of the animals. Especially, the lower part can be made of gravel to drain water accumulated on the cover layer smoothly .

The lower plate 110 of the girder block 300 may be composed of a flat portion 116, an inclined portion 114 and a reinforcing portion 112.

The flat portion 116 is a flat surface forming a portion adjacent to the wall 120 and forming a part of the planting space while providing a space for installing the drain 200.

The flat portion 116 can be planted such as a tree with a deep root at the deepest depth of the subsoil in the lower plate 110. Therefore, the flat portion 116 can be a basis for constructing a small ecosystem by arranging the surrounding environment with the planting of trees.

The flat portion 116 provides a space in which the drain 200 capable of discharging the water intensively dripping from the inclined portion 114 or the superficial layer to the outside of the lower plate 110 is installed and imposed on the lower plate 110 Or to transmit the load to the bridge pier 400. [0050]

The inclined portion 114 may extend from the end of the flat portion 116 to form a connection portion of the connection block 500 and may extend in an inclined relation with the flat portion. That is, the inclined portion 114 is inclined toward the connection block 500 to help natural drainage of water dripping from the ground layer, and also to distribute the load imposed on the lower plate 110.

The reinforcing portion 112 is formed by distributing the load to the inclined portion 114 and the flat portion 116 through the bent portion while connecting the inclined portion 114 and the flat portion 116 in a bent state, And the like.

Here, the bending (out-of-plane) structure applied to a building or a large structure is a function of the change in cross-sectional shape due to the folding of the transverse beam action and the longitudinal beam action , And each cross section is integrally connected to transmit the force in the longitudinal direction.

 The advantage of bending (out-of-plane) structure is that the force is transmitted by the principle using the folding characteristic and bending moment is generated on the out-of-plane surface, but the main stress acts mainly as the surface resistance, It is possible to construct a vibrating structure.

For example, the reinforcing portion 112 is formed by the inclined portion 114 and the flat portion 116 of the lower plate 110 being folded into an integral plate-like shape while being bent by the inclined portion 114 and the flat portion 116, 110 can be distributed and arranged.

Therefore, the lower plate 110 can increase the rigidity using the reinforcing portion 112 without the need for additional reinforcement of the beams, and can drastically reduce the cross-sectional area, which facilitates the construction and thus reduces costs due to shortening of the air .

Also, the bending (half-plate) structure is composed of the same flat plate and is easily processed in the joining portion, so that the construction is simple.

Accordingly, the constructor can apply the bending structure to the ecological moving leg 10 to drastically reduce the cross-sectional area, thereby reducing the shielding area and utilizing various spaces as well as various designs.

Due to the above-mentioned reasons, the structure of the bending structure is well received, and it is being actively applied not only to construction, civil engineering but also other industrial fields.

The girder block 300 may be a configuration that further includes a tension member 112.

The tensile member 112 may be a plurality of reinforcing bars embedded in the lower plate 110 of the girder block 300 to generate tensile stress corresponding to a tensile force.

The connection block 500 may be constructed to correspond to the longitudinal direction of the girder block 300 and have a connection portion formed at a portion thereof for heating the pair of the girder blocks 300.

The connection block 500 has a length determined according to the longitudinal direction of the connection block 500 for burying the auxiliary tension material, which is made of reinforcing steel, in the lower portion corresponding to the tensile stress generated depending on the amount of the soil layer that is partially concentrated and laminated A plurality of auxiliary tensile material receiving holes 510 may be formed.

The auxiliary torsion material is a steel wire made of a general pre-reinforced steel material, and it can reinforce a tensile force by giving stress in advance to the stress generated in the girder (100).

The connecting member 310 is a part of the girder block 300 so as to be connected to the pair of the girder blocks 300 at the connecting portion of the connecting block 500. Specifically, Lt; / RTI >

The operator can assemble the connecting member 310 of the girder block 300 and the connecting block 500 with a single girder 100 using mortar or the like.

The girder 100 can be constructed by the concrete pouring method using the mold 600 using the connecting members 310 of the inclined portion 114 which are mutually symmetrical.

That is, the worker can construct the work by using the existing work 600, and various work environments can be selected according to the situation.

The drain 200 is a component installed on the girder and draining water discharged from the ground layer to the outside of the girder.

The drain 200 is a kind of guide pipe, and the upper part is formed of a mesh net to guide drainage of water dripping from the ground layer. The guide pipe is formed in a pipe shape and is piped to the flat part 116 in the longitudinal direction of the lower plate, And the upper part is made of mesh net so that the water drained from the ground layer can be collected through the mesh net and guided to the outside of the lower plate 110.

The guide pipe is a pipe through which sewage passes, and can be made of steel or PVC. The guide pipe may be made of a meshed mesh having a dense upper portion and a thick mesh network, so that the soil that can descend together from the ground layer is filtered and can be guided to be drained to the outside of the lower plate 110 only by receiving water.

The girder block 300 also includes reinforcing bars providing tensile strength corresponding to the tensile stresses generated in the upper portion of the wall 120. The reinforcing bars are formed in the wall 120 at a predetermined length above the wall 120 supported by the bridge pier 400, As shown in Fig.

In the method of constructing a prefabricated ecological moving bridge using the bent type girder according to the present invention, a worker transports the prefabricated girder block 300 and the connecting blocks 500 manufactured in a factory to the field to connect the connecting material 310 and other connecting members It is possible to construct the ecological moving bridge 10 which can shorten the air time and the construction is easy and the cost can be reduced.

In addition, the operator may merge the existing construction methods to fabricate the girder blocks 300 on the site using the formwork 600 to assemble the prefabricated girders.

In other words, the worker can select the worker according to the work environment or the worksite. In such a case, the worker takes the already prepared girder block 300 and assemble the worker using the worker 600 in the field. It will be significantly shortened, air can be saved, construction will be easier and cost reduction will be achieved.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And such variations and modifications are intended to fall within the scope of the appended claims.
