A description will be given of an example in which a traveling drive device 13 having a traveling surface as a traveling surface is installed above the support 11. In this example, the traveling drive device 1
Reference numeral 3 denotes a rotation mechanism of the endless belt 14, which is capable of trackless traveling. As the traveling drive device 13, a system using wheels may be used. In addition, the traveling drive device 13 can be provided with a turning mechanism 15 for rotating the traveling drive device 13 around a vertical axis in order to change the traveling direction of the traveling drive device 13. The pushing of the traveling drive device 13 against the traveling surface of the bridge structure lower surface 1a depends on the buoyancy received by the floating body 6, but the pushing mechanism 16 can be attached.
The pressing mechanism 16 absorbs fluctuations in the horizontality of the running surface of the lower surface 1a of the bridge structure, adjusts when the water level changes, and temporarily lowers the running drive device 13 before the turning mechanism 15 is operated for changing the running direction. It corresponds to various purposes such as operation. According to these purposes, the traveling drive device 13 includes a shock absorber,
An elastic rubber, an airbag, a cylinder mechanism or the like may be appropriately selected.

で移動することが可能である。Next, an example in which work is performed on the lower surface of the bridge structure using the pier structure lower surface working apparatus of the present invention will be described. The pier structure lower surface working device is shown in FIGS. 1 and 2 while being guided by a work boat (not shown) or a winch installed on the pier structure and a rope coupled to the pier structure lower surface working device. 5 is moved to a predetermined work position. In the case where the traveling drive device is installed in the pier structure lower surface working device, the pier structure lower surface working device is caused to self-run while the traveling drive device 13 (for example, an endless belt or a wheel) is pressed, It is possible to move to a predetermined position. Subsequently, the arm mechanism 7 of the fixing mechanism 9 for fixing the floating body 6 to the support pile 2 of the pier structure 1 is driven, and the support pile 2 is gripped by the gripper 8.
When the holding of the support pile 2 is completed by all the fixing mechanisms 9, it is possible to suppress horizontal and vertical movements of the device for working on the underside of the pier structure due to waves, wind, etc. The device is stationary as shown in FIG. Floor structure 1 for pier structure underside work equipment
If the zero elevation drive 24 is installed, the floor structure 10 is moved and adjusted to an appropriate height at this point. In this state, the floor structure 10 is stably held, so that a work scaffold is secured, and work can be performed on the lower surface 1a of the bridge structure. When the operation is completed, the gripper 8 is opened to release the pile, and the arm mechanism 7 is driven to store the gripper 8 in a predetermined position as shown in FIG. Next, the pier structure lower surface working device is guided by a work boat (not shown) or a winch installed on a not shown bridge structure and a rope connected to the pier structure lower surface working device. Withdraw from your current location. If necessary, the user may be moved to the next work position and the above procedure may be repeated. In addition, when the traveling drive device is installed on the pier structure lower surface working device, the pier structure lower surface working device is caused to self-propell while the traveling drive device is pressed against the underpass structure lower surface 1a. It is possible to leave the position or move to the working position.

業の安全性が確保される。According to the present invention, since a floor structure serving as a work scaffold is installed above a movable floating body, it is possible to move a device for working on a lower surface of a pier structure on water, and a bridge structure is provided. It is easy to enter and leave the work area on the lower surface. Therefore, as compared with the conventional temporary scaffold, even when the work position is far from the end of the bridge structure, the work scaffold can be installed and removed in a shorter time. In addition, a reaction force is applied to the support pile of the bridge structure by the fixing mechanism, and the device for working on the underside of the pier structure can be stopped at a predetermined position, so that the suspending pieces and other support members required for the conventional temporary scaffolding are provided. A stable working scaffold can be secured without installing the work in the bridge structure.
Therefore, compared with the case of using a conventional temporary scaffold, it is possible to shorten the construction period and expand the applicable range. Also, work safety is ensured.
