DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
1 to 6 show an embodiment of a hose bridge according to the present invention. As shown in FIGS. 1 and 2, the hose bridge 1 includes two horizontal bridges 2 and two first bridges that are respectively connected to the ends of the horizontal bridge 2 in the front-rear direction (vehicle traveling direction a). And two second inclined bridges 4 respectively connected to the front and rear ends of the first inclined bridge 3.

  The horizontal bridge 2 has a horizontal road surface portion 2a having a predetermined thickness, and a pair of leg portions 2b having the same height and standing vertically on the front and rear lower surfaces of the road surface portion 2a. Connected along the direction. In the horizontal bridge 2, a space 5 is formed between the road surface portion 2 a and the pair of leg portions 2 b so as to open in the left-right width direction (direction orthogonal to the traffic direction A). That is, the height h (see FIG. 4) of the leg 2b is formed to be slightly larger than the outer diameter of the drainage hose 6 (see FIGS. 5 and 6), and the width of the space 5 in the front-rear direction is additionally provided. The dimension which can accommodate the several hose 6 to be accommodated is set.

  The first inclined bridge 3 is connected to the front and rear of the horizontal bridge 2, respectively, and has a road surface portion 3a having the same thickness as the horizontal bridge 2 and inclined at a predetermined angle, and is perpendicular to the front and rear lower surfaces of the road surface portion 3a. It has a pair of leg portions 3b with different heights, and the height of the leg portion 3b on the horizontal bridge 2 side is set higher than the height of the leg portion 3b on the second inclined bridge 4 side. In addition, the second inclined bridge 4 is, like the first inclined bridge 3, a distal end portion (one end portion) on the anti-horizontal bridge 2 side of the road surface portion 4 a having the same thickness as the road surface portion 2 a of the horizontal bridge 2. In addition, an installation surface 4c to the road surface R on which the hose 6 is disposed is formed, and a leg portion 4b having a predetermined height is formed on the lower surface of the road surface portion 4a on the first inclined bridge 3 side.

  And each bridge | bridging 2-4 is illustrated by setting the height of each leg part 2b, 3b, 4b of the horizontal bridge 2, the 1st inclination bridge 3, and the 2nd inclination bridge 4 to the continuous predetermined height. When connected as shown in FIG. 1 and FIG. 2, the passage surfaces formed on the upper surfaces of the road surface portions 2 a to 4 a of the bridges 2 to 4 are formed to be flat and continuous surfaces.

  As shown in FIG. 2, the road surface portions 2 a to 4 a of the bridges 2 to 4 are a pair of square pipes having a predetermined length provided at both ends in the left-right width direction orthogonal to the traffic direction A of the vehicle. The frame 7 is composed of a road surface body 8 made of a plurality of square pipes, a plate body having a predetermined thickness, and the like having a predetermined gap and having both ends fixed by welding between the pair of frames 7. It is made of an aluminum material to reduce its weight. At this time, it is preferable that the upper surface of the frame 7 of the road surface portions 2a to 4a and the upper surface of the road surface body 8 are set to be flush with each other. However, for example, the width of the road surface portions 2a to 4a is relatively wider than the tire width of the vehicle. If set, the upper surface of the road surface body 8 may be set lower than the upper surface of the frame 7 so as to prevent the wheel from being removed from the road surface portions 2a to 4a.

  In addition, a pair of lifting hooks 9 for lifting the bridges 2 to 4 by heavy machinery or the like are welded and fixed at substantially intermediate positions in the longitudinal direction outside both side surfaces of the frames 7 of the bridges 2 to 4, respectively. The recesses 10 (or openings) are provided for weight reduction. Furthermore, the leg portions 2b to 4b of the bridges 2 to 4 are disposed over the entire area in the width direction of the road surface portions 2a to 4a, or a pair having a predetermined length at both ends in the width direction. It is arranged.

  The bridges 2 to 4 are connected as shown in FIGS. That is, the locking portion 11 bent in an L shape on the left and right sides in a plan view is provided at a substantially intermediate position in the height direction of the front ends of the leg portions 2b to 4b of the horizontal bridge 2 and the inclined bridges 3 and 4 in the front-rear direction. The base end is welded and fixed, and at the intermediate position in the height direction of the rear ends of the legs 2b to 4b of the bridges 2 to 4, the L is bent inward and leftward in plan view in the opposite direction to the locking portion 11. The base end portion of the letter-shaped locking portion 12 is fixed by welding. At this time, a yellow paint is applied to the entire locking portion 11, and a green paint is applied to the entire locking portion 12, so that both the locking portions 11, 12 are identified by color. Has been.

  For example, of the two horizontal bridges 2, the front horizontal bridge 2 is installed at a position where the hose 6 at the drainage site is disposed, and the horizontal bridge 2 is connected to the locking portion 12 at the rear end of the horizontal bridge 2. The front end locking portion 11 is locked from above, and the rear horizontal block 2 is connected to the front horizontal bridge 2. In addition, the locking portion 11 at the front end of the horizontal bridge 2 on the front side or the locking portion 12 at the rear end of the horizontal bridge 2 on the rear side is connected to the locking portion 12 at the rear end of the first inclined bridge 3 on the front side or The locking portion 11 at the front end of the first inclined bridge 3 on the rear side is locked from above to connect each first inclined bridge 3 to the horizontal bridge 2 on the front side and the horizontal bridge 2 on the rear side.

  Similarly, the second inclined bridge is connected to the front and rear first inclined bridges. At the time of this connection, the movement in the left-right width direction of each of the bridges 2 to 4 to be connected is restricted by the locking by the L-shaped locking portions 11 and 12 in plan view. These connecting operations are performed, for example, by lifting and lifting the arm end of a heavy machine via a wire or the like to the hook 9, and a pair of hose bridges 1 each having the bridges 2 to 4 are separated by a predetermined distance (distance). ) Will be installed at the drainage site.

  In this installed state, as shown in FIGS. 5 and 6, for example, a plurality of (two in the figure) hoses 6 provided in each space 5 of each horizontal bridge 2 are accommodated. The upper surface side of the hose 6 is protected by the road surface portion 2 a of the horizontal bridge 2. As a result, even if the vehicle passes through the upper surfaces of the road surface portions 2 a to 4 a of the pair of hose bridges 1, the bridges 2 to 4 can withstand the weight of the vehicle and are accommodated in the space 5 of the horizontal bridge 2. The plurality of hoses 6 are not deformed, and each hose 6 is reliably protected to prevent the drainage function from being lowered.

  On the other hand, when the drainage operation is completed and the hose bridge 1 is removed, the hook 9 and the heavy machinery are used to lift the second inclined bridge 4 and lock it with the first inclined bridge 3 as in the installation. Release the state. Similarly, each horizontal bridge 2 is lifted to release the locked state with each first inclined bridge 3. Thereby, the latching state of the horizontal bridge 2 and each inclination bridge | bridging 3 and 4 is cancelled | released, and each bridge | bridging 2-4 becomes a solid body, for example, is loaded on a transport vehicle and removed from the drainage field.

  That is, in the case of the hose bridge 1, a predetermined number of horizontal bridges 2 and inclined bridges 3, 4 are prepared according to the situation of the drainage site, and these are connected at the drainage site, whereby a pair of hose bridges 1 are predetermined. Install at intervals. At the time of installation, the bridges 2 to 4 are connected while being moved in the up-down direction to be connected in a state in which movement in the left-right width direction is restricted from the locking portions 11, 12, and the horizontal bridge 2. A plurality of drain hoses 6 provided in the space 5 are accommodated. Thus, the installation work is completed, and the removal work can be performed in the reverse procedure of the installation work.

  Thus, according to the hose bridge 1, the horizontal bridge 2 having the road surface portion 2a and the leg portion 2b and having the space 5 opened in the left-right width direction therebetween, and the front and rear of the horizontal bridge 2 are provided. The hose bridge 1 is formed by the first inclined bridge 3 and the second inclined bridge 4 respectively connected to both ends in the direction, and a pair of these is arranged with a predetermined distance in the left-right width direction. Since the hose is inserted and arranged in the space 5 of the pair of horizontal bridges 2, a plurality of hoses 6 to be provided can be accommodated in the space 5 of the horizontal bridge 2 to protect them at the same time, The drainage work at the time of occurrence can be performed reliably and efficiently regardless of the traffic of the vehicle.

  Also, the vehicle can be passed by simply installing a pair of hose bridges 1 each connecting two horizontal bridges 2 and a total of four inclined bridges 3 and 4 on the road surface R of the drainage site at a predetermined interval. Therefore, the installation work can be performed quickly and reliably, and the removal work after the completion of drainage can be easily performed, so that it is possible to accurately and quickly cope with the occurrence of a disaster or the like.

  The inclined bridge includes a first inclined bridge 3 connected to the horizontal bridge 2 and a second inclined bridge 4 connected to the first inclined bridge 3 and having an installation surface 4c at one end. Therefore, when the outer diameter of the hose 6 is large and the height of the horizontal bridge 2 is increased, the inclination angle of the first inclined bridge 3 or the second inclined bridge 4 with respect to the horizontal bridge 2 can be set gently. The vehicle can pass through the hose bridge 1 satisfactorily.

  Furthermore, the front and rear end portions of the horizontal bridge 2 and the inclined bridges 3 and 4 have key-shaped locking portions 11 and 12 for restricting movement in the left-right width direction. Since the bridges 2 to 4 are detachably connected by locking from the direction, the bridges 2 to 4 can be easily connected by locking the locking portions 11 and 12, and the installation work can be performed more easily. At the same time, movement in the left-right direction is restricted by the locking portions 11 and 12, so that the installed state can be stably maintained, and the vehicle on the hose bridge 1 can be stably and safely performed.

  Moreover, since the latching | locking parts 11 and 12 of each bridge | bridging 2-4 connected are distinguished by the different color, for example, by locking the latching | locking parts 11 and 12 from which colors differ, each bridge | bridging 2 4 can be connected easily and reliably without making a mistake in the front-rear direction, and the installation work of the hose bridge 1 can be performed more easily. Further, each of the bridges 2 to 4 includes a pair of long frames 7 provided on both sides in the left-right width direction, and a plurality of road surface bodies 8 fixed by welding with a predetermined gap between the frames 7. Since these are formed of an aluminum material, the weight of the bridges 2 to 4 can be reduced, and the installation and removal work can be performed more easily.

  In the embodiment, the hose bridge 1 is composed of two horizontal bridges 2, two first inclined bridges 3 and two second inclined bridges 4, that is, a total of six bridges 2 to 4. However, the present invention is not limited to this. For example, the number of horizontal bridges 2 is one, the first inclined bridge 3 is omitted and only the second inclined bridge 4 is used, or the first inclined bridge 3 is used. The number of each of the bridges 2 to 4 can be appropriately set according to the form of the drainage site, such as 3 or more.

  Moreover, in the said embodiment, although the planar-view L-shaped latching | locking part 11 and 12 provided in the front-and-back end of each bridge | bridging 2-4 was identified by the color, for example, the shape itself of the latching | locking part 11 and 12 is used. The shapes of the locking portions 11 and 12 themselves are not limited to the L shape in plan view, and may have an appropriate structure such as a circular arc shape in plan view. Furthermore, the configuration of the widths and heights of the bridges 2 to 4 in the above-described embodiment, the connection structure of the bridges 2 to 4 and the like are also examples, and an appropriate configuration that can obtain the same effect is adopted.
