Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that removes the required thickness 11 of the OW roadbed while leaving an upper layer of snow remaining at the current location that can be used as a roadbed material.

Generally, when repairing an asphalt pavement road that is currently in use, the asphalt pavement and the underlying roadbed are simultaneously crushed to a particle size of 50 particles or less at the current location, and cement, limestone stabilizers, and water are applied to this. In addition, it is mixed to perform shaping compaction.
In this way, the old roadbed has been regenerated as a roadbed, and 5 to 101 new asphalt pavements have been constructed on this regenerated roadbed. In addition, when converting an il'1% road into a one-way road, the upper gravel layer is used as roadside material, and paving is done on top of it.As mentioned above, the existing material is recycled. Roadbed”*
*The above method increases the height of the road surface by at least the thickness of the new pavement. Furthermore, the road to be repaired has usually already undergone several repairs and is often already higher than the planned road surface.

Therefore, in the above-mentioned repair method, various problems occur due to the height of the road surface becoming higher and higher.For example, in shopping techniques, the road surface becomes higher than the floor of the store,
It will be necessary to raise the height of structures such as flagstones, drainage ditches, and manholes.

In order to avoid the above-mentioned obstacles, the construction method is generally used for renovation.φ
In case, the roadbed material is placed so that the roadbed surface is at the specified height**
methods are being used. However, the above method is not economical because the actual roadbed material is discarded. Therefore, once the crushed roadbed material is transported and temporarily stored elsewhere,
Another method is to take a look at the exposed roadbed and return the temporarily stored roadbed material on top of the exposed roadbed without increasing it slightly. Method C has the advantage of not having to discard the actual roadbed material, but it requires manpower and time, and has the disadvantage of requiring particularly time-consuming traffic control.The present invention was developed in view of the above circumstances. The purpose of this is to provide a device that can leave the subgrade material in its current location and scatter the subgrade soil underneath to a predetermined thickness. Wheels for running were installed, and between the front wheels and the rear wheels, there was installed a cutting device that scraped the existing road and sent it backwards, and an excavator that scoured the exposed roadbed. be.

is provided. The motors and hydraulic cylinders are driven and the device travels using the power as a drive source, and each operation can be easily performed by an operator.

Next, we will explain how to use the device according to the present invention configured as above. First, operate the hydraulic cylinders 22, 24, 28 to raise the front and rear excavation equipment 6.17 and the support member 27 so that they do not touch the ground. Do it like this. After that, it moves on its own with 4 front and rear wheels 2.3 and moves to the construction site. At the construction site, the asphalt pavement a is crushed alone or together with the roadbed using a crusher etc. at the current location (on the road). At such a construction site where the number of workers is slightly increased to a predetermined height, the hydraulic cylinders 22, 24, and 28 are operated to lower each of the devices to a predetermined height. In this case, in order to drive the lower end of the excavating device 6.17 into the roadbed, it is temporarily driven.Then, the front and rear excavating devices 6, 17, screw 2B, compactor 26, belt conveyor 21 are driven, and the wheels 2.
3 to run the device at a slow speed.

Through the above operation, the roadbed material A is extracted from the front packet excavator 6m, (!s) and the screw excavator 14a with a pre-excavation value of 6.
, 14b. screw excavator 14m
, 14b is sent to the front packet excavator 61.6all, and transported upward by the packet 13.

Furthermore, as the roadbed material A is excavated and removed, the exposed roadbed B is cut into predetermined dimensions by the rear excavation device 17 as the device advances, and is conveyed upward by the packets 13 . be dropped on top. The subgrade soil dropped onto these belt conveyors 21 and 21 is transported and loaded onto a transport vehicle (111 not shown) or the like that runs in front of the device and is crushed.

Moreover, on the scattered roadbed B', the above-mentioned front excavation device 6
The roadbed material is transported upward and dropped through the plate body 23. This dropped roadbed material is spread out in the left-right direction by screws 25 and compacted by a compactor 26 to form surface A2.

In addition to the above-mentioned work, the AM according to the present invention can also be used as a plowing machine in the construction of roads, plazas, and other construction works for the purpose of loosening soil that has become too thick on the surface compared to conventional machines. It can also be used.

As mentioned above, the height of the surface constructed by this device is reduced by the amount corresponding to the thickness of the subgrade soil that has been scattered, so if you control the thickness of the subgrade soil to be removed, By slightly increasing the thickness of the roadbed to the required thickness, it is possible to obtain the required thickness without wasting good quality roadbed material. In addition, road O repair is often carried out with a platform open to traffic. In this case, the original @0 device can perform the same work using another platform or loading device. Compared to conventional methods, the work surface occupied is extremely small, and the work can be completed in a short time (traffic control).The time required to perform the work (traffic control) is also short.Furthermore, the width to be excavated by the front and rear O1L cutting equipment is the same, so the excavation is done evenly during this time. I can do it. In addition, since the hydraulic cylinders are installed on the left and right sides of each excavation rig, the lower end of each excavation rig can be moved up and down freely. Moreover, the height of the left and right sides can be changed to a certain extent, and the construction can be carried out while avoiding obstructions, etc., and the construction time can be shortened.
