May be “connected”, “coupled” or “connected”.

Hereinafter, a composite crosslink according to an example of the present invention will be described in detail with reference to FIGS. 1 to 5.

1 to 3, the composite bridge according to an embodiment of the present invention in a composite bridge for bypass or construction installed in a river, lake or sea, steel bridge is constructed in the deep portion of the river, lake or sea (10) and being constructed in other sections may include a shaft diagram 20 to be constructed so as to be connected to the steel bridge (10).

The present invention can be usefully applied to the construction of a bypass bridge or construction bridge for the passage of vehicles or people for the construction of bridges in rivers, lakes or seas, or for repairing pre-installed bridges.

In the present embodiment, the composite bridge may include a steel bridge 10 and a shaft 20.

The steel bridge 10 may be constructed in a deep portion of the section for installing bridges in rivers, lakes or the sea.

The shaft diagram 20 to be connected to the steel bridge 10 may be constructed in a section other than the region in which the steel bridge 10 is installed. That is, a section not deep in construction can be constructed by the shaft diagram 20.

The shaft 20 may be constructed using the earth-filled geotextile tube or sack 22. Hereinafter, the earth-filled geotextile tube or stem 22 is briefly described as earth-filled geotextile tube for convenience of description.

The earth-filled geotextile tube 22 may be laminated by filling the soil inside the geotextile tube.

The shaft 20 may be formed by the whole surface is laminated with the earth-filled geotextile tube 22, or the outer surface, both sides and the top surface is laminated with the earth-filled geotextile tube 22 and the inside of the earth is filled with soil. . That is, the construction method of the shafting shaft may be changed in consideration of the scale, the water depth, the flow velocity, the hydraulic pressure, etc.

For example, when the flow velocity is fast or the hydraulic pressure is strongly applied, the entire cross section of the shaft 20, that is, the outer and inner surfaces of the shaft 20 is formed by stacking earth-filled geotextile tubes 22, and the flow velocity is relatively slow or When the hydraulic pressure acts weakly, the outer surface of the shaft 20 may be formed by stacking earth-filled geotextile tubes 22 and laying soil inside. Among the above methods, it is preferable to select a suitable method in consideration of economics and stability.

The shaft 20 may further include a protective geotextile or tarpaulin (24) covering the upper surface. The protective geosynthetic fiber or tarpaulin 24 is wrapped upstream of the earth-filled geotextile tube 22 upstream on the upstream side, and then simply overlapped or sewn on the downstream side, and the earth-filled geotextile tube 22 downstream on the downstream side. ) Can be sewn on the downstream side and stitched on the lower side.

That is, the protective geosynthetic fiber or tarpaulin 24 covers the upper surface of the shaft 20, and wraps one or two earth-filled geotextile tubes 22 on the upstream side and the downstream side of the upstream side and the downstream side thereof, It can be joined or bonded with the geosynthetic tube of the fiber tube (22).

The protective geosynthetic fiber or tarpaulin (24) is confined to the earth-filled geotextile tube (22) of the uppermost and downstream side of the protective geosynthetic fiber or tarpaulin (24) when the water overflows the shaft 20 due to flooding At the same time, by protecting the upper surface of the shaft 20, the shaft 20 can be prevented from being collapsed or lost.

The packaging layer or topsoil layer 30 may be further formed on the upper surface of the protective geosynthetic fiber or waterproof cloth 24. The pavement layer or topsoil layer 30 is configured to finish the upper side, and facilitates traffic such as a vehicle, and at the same time, water can be prevented from penetrating the inside of the shaft 20 when water overflows.

The shaft 20 may be provided with drain pipes 50 so that water flows from the upstream side to the downstream side. The drain pipes 50 may be spaced apart at a predetermined interval upward from the lower end of the shaft portion 20. This can prevent the bottom from being crushed by the flow of water to the drain pipe 50, and at the same time, it is possible to prevent the drain pipe 50 from being clogged by sediment deposition on the lower side. The drain pipes 50 may be installed to penetrate the shaft 20 from the upstream side to the downstream side of the shaft 20 and protrude a predetermined length from the side of the shaft 20. The protrusion of the drain pipe 50 makes it possible to prevent the soil filling geotextile tube 22 near the drain pipe 50 from collapsing.

The contact surface of the shaft 20 in contact with the alternating portion of the steel bridge 10 may be formed by stacking earth-filled geotextile tube 22 in a stack. That is, the earth-filled geotextile tubes 22 are stacked in contact with the alternating portion of the steel bent portion of the steel bridge 10 to be stacked and connected to the steel bridge 10 alternate surface. This may prevent the shaft 20 from being lost by the water flowing into the steel bridge 10 vent part.

Connection slab 40 may be formed on the upper surface of the shaft 20 in contact with the alternating portion of the steel bridge (10). The connecting slab 40 allows the upper surface of the alternating portion of the steel bridge 10 and the upper surface of the shaft 20 to be continuously connected, thereby making it possible to smoothly pass a vehicle.

In addition, the alternating portion of the steel bridge 10 may be provided with a connecting member on the side in contact with the shaft 20. That is, the coupling member coupled to the alternating portion of the steel bridge 10 and having a connection member embedded in the shaft 20 may maintain the integrity of the shaft diagram 20 adjacent to the alternating portion of the steel bridge 10. The shaft 20 is coupled to the rigid steel bridge 10, thereby increasing the stability of the shaft 20 against flooding, and at the same time preventing passage of the shaft 20 in contact with the steel bridge 10 so as to smoothly travel. It can be done.

For example, the wire mesh, iron plate, reinforcing bars, iron rods, etc. are welded to the steel bridge (10) and then extended to the inside of the shafting 20 is embedded, or geotextiles, sheets, etc. are coupled to the steel bridge 10 after the shafting (20) ) And may be embedded inside. Such wire mesh, geotextiles, etc. can be installed in multiple layers up and down.

In the present embodiment, the foundation pile of the bridge structure may be constructed at the side bridge 60 protruding laterally from the composite bridge itself or the composite bridge. When the foundation pile is constructed in the composite crosslinking itself or the siding unit 60, it is more economical than the case of construction in the water and construction performance can be significantly improved, the construction quality can be excellent. In addition, the foundation pile of the bridge structure may be constructed directly on the shaft 20 of the composite bridge itself or the shaft 20 of the side section (60).

Referring to FIG. 4, after passing through the middle portion of the shaft diagram 20, the first tension member 70 and the upper end of the shaft diagram 20 that are tension-bonded at the lower portion of the upstream side and the downstream side of the shaft diagram 20 are passed. It may further include a second tension member 72 that is tension-bound in the upstream lower portion and the downstream lower portion of the shaft 20.

The first tension member 70 and the second tension member 72 press and tension and bind the earth-filled geotextile tubes 22 forming the shaft 20, so that they can withstand high flow rates and strong hydraulic pressure. This improved shafting 20 can be constructed.

The first tension member 70 and the second tension member 72 are bound to the inclined fixing portion 82 coupled to the upper end of the temporary pile 80 installed at the lower side upstream and downstream of the shaft 20. Or may be bound to an upstream end portion and a downstream end portion of the drain pipe 50 installed in the shaft 20.

Referring to Figure 4a, the first tension member 70 and the second tension member 72 is coupled to the upper end of the hypothesis pile 80 which is respectively installed in the upstream lower and downstream downstream of the shaft 20 (20). It is possible to bind more firmly to the earth-filled native fiber tubes forming the shaft 20 by being bound to the accident government 82. The temporary pile 80 may increase the stability of the shaft 20 by binding the first tension member 70 and the second tension member 72 and supporting the foundation of the shaft 20.

Referring to FIG. 4B, the first tension member 70 and the second tension member 72 may be tightly coupled to the upstream end portion and the downstream end portion of the drain pipe 50 provided with the shaft 20. This has the effect of easily binding without having a separate configuration for binding the first tension member 70 and the second tension member 72.
