former road base mechanism of dull and stereotyped laminating is including fixing the first extension board 10 on first backup pad 2, it is connected with second threaded rod 11 to rotate on the first extension board 10, threaded connection has two latch segments 12 on the second threaded rod 11, notch 17 has been seted up at 2 tops of first backup pad, there is sliding block 8 at the top of first backup pad 2 through 13 spacing sliding connection of spacing spout, sliding block 8 is connected with second backup pad 1, two latch segments 12 can be fixed with sliding block 8, thereby it is fixed after the horizontal offset position of adjustment second backup pad 1 and first backup pad 2. With the rapid development of socioeconomic in China, most of the functions of the existing roads can not meet the increasing traffic demand of the society, so that the original roads are imperatively upgraded and modified. The key of the engineering reconstruction is the widening of the highway subgrade, namely the design and the construction. After many years of traffic, the subgrade settlement is basically completed, and the widening section of the subgrade inevitably generates cracks represented by longitudinal cracks due to the uneven settlement of a new subgrade and an old subgrade, so that the highway is damaged. Therefore, design optimization and construction quality during highway subgrade widening must be enhanced, and settlement is reduced to the minimum so as to ensure the quality of the highway. General personnel can be to the original roadbed need widen the position and measure the lofting, mark out and need widen the position, dig the domatic along original roadbed side slope angle step by step, and the platform between the domatic at different levels descends by step from the road surface to lower width. The surface of different slopes is generally fixed by a flat plate, so that the uneven settlement can be greatly reduced by paving sand and stones. However, since the slope is excavated by the personnel on the original roadbed, the states of the platforms excavated on the original roadbed are not necessarily as expected, and a mechanism capable of adjusting the states of the platforms is required to improve the uneven settlement prevention device for the old roadbed and the new roadbed. First with first backup pad 2, second backup pad 1, each platform that former road bed excavated is put to third backup pad 3, then for making first backup pad 2, second backup pad 1, the better laminating of third backup pad 3 is on the platform, remove sliding block 8, sliding block 8 drives second backup pad 1 and removes left or right side, it makes third backup pad 3 remove left or right side to remove sliding block 8 in the second backup pad 1, then rotate two latch segments 12, two latch segments 12 pass through screw-thread fit, make sliding block 8 fixed. Thereby completing the attachment of the device to each platform excavated by the original roadbed. The ground piles are used for fixing the ground piles on the original roadbed, and gravels are paved and compressed.
Specifically, as shown in fig. 4, the former roadbed mechanism of dull and stereotyped laminating still includes first threaded rod 5, and the screw hole 9 that is linked together with notch 17 is seted up at 8 tops of sliding block, and screw hole 9 internal thread is connected with first threaded rod 5, and the bottom fixedly connected with cylinder 6 of first threaded rod 5, the outer wall sliding connection of cylinder 6 has round cover 7, and round cover 7 passes through the bearing and rotates the connection on second backup pad 1. The first threaded rod 5 is rotated, and the round sleeve 7 on the second support plate 1 is rotated through the circumference by matching with the threaded hole 9 in the sliding block 8, so that the distance between the two support plates can be adjusted up or down. Thereby make horizontal position and height position between two backup pads all adjustable, be convenient for make the platform laminating of the device and the last a plurality of levels of digging of former road bed.
Specifically, as shown in fig. 6, the outer wall of the cylinder 6 is fixedly connected with a second extending plate 15, the inner wall of the round sleeve 7 is provided with a groove 16, and the second extending plate 15 is in limited sliding connection in the groove 16. So that the first threaded rod 5 steadily makes the distance between the two support plates smaller or larger.
Specifically, as shown in fig. 1, fixing holes 14 are formed in the first support plate 2, the second support plate 1, and the third support plate 3, and the fixing holes 14 cooperate with the wooden piles to fix the first support plate 2, the second support plate 1, and the third support plate 3 on the original roadbed. So that each support plate is stably fixed on the original roadbed.
Specifically, as shown in fig. 1, a rotating wheel 4 is fixedly connected to the top of the first threaded rod 5. Rotation of the first threaded rod 5 is facilitated.
Specifically, as shown in fig. 1, two second threaded rods 11 are provided, and cooperate with the locking blocks 12 to fix both sides of the sliding block 8. So that the sliding block 8 is stably fixed.
Specifically, as shown in fig. 1, the outer wall of the locking block 12 is marked with a print, so that a person can rotate the locking block 12 conveniently.
In the embodiment, with the rapid development of socioeconomic performance in China, most of the functions of the existing roads cannot meet the increasing traffic demand of the society, so that the original roads are inevitably upgraded and modified. The key of the engineering reconstruction is the widening of the highway subgrade, namely the design and the construction. After many years of traffic, the subgrade settlement is basically completed, and the widening section of the subgrade inevitably generates cracks represented by longitudinal cracks due to the uneven settlement of a new subgrade and an old subgrade, so that the highway is damaged. Therefore, design optimization and construction quality must be enhanced when the highway subgrade is widened, and settlement is minimized to ensure the quality of the highway. General personnel can be to the original road bed need widen the position and measure the lofting, mark out and need widen the position, dig the domatic step by step along original road bed side slope angle, and the platform between the domatic at all levels is by the road surface to width degressive step by step down. A flat plate is generally adopted for fixing the slope surfaces, so that the uneven settlement can be greatly reduced when sand is paved. However, since the slope is excavated by the personnel on the original roadbed, the states of the platforms excavated on the original roadbed are not necessarily as expected, and a mechanism capable of adjusting the states of the platforms is required to improve the uneven settlement prevention device for the old roadbed and the new roadbed. First with first backup pad 2, second backup pad 1, on each platform that former road bed excavated was put to third backup pad 3, then for making first backup pad 2, second backup pad 1, the better laminating of third backup pad 3 is on the platform, remove sliding block 8, sliding block 8 drives second backup pad 1 and removes left or right side, it makes third backup pad 3 remove left or right side to remove sliding block 8 in the second backup pad 1, then rotate two latch segments 12, two latch segments 12 pass through screw-thread fit, make sliding block 8 fixed. Then, the first threaded rod 5 is rotated, the threaded holes 9 in the sliding blocks 8 are matched, and the round sleeve 7 on the second support plate 1 is rotated through the circumference, so that the distance between the two support plates can be adjusted up or down. Thereby make horizontal position and high position between two backup pads all adjustable, be convenient for make the device laminate with the platform of a plurality of levels of digging on the former road bed. The ground piles are used for fixing the ground piles on the original roadbed, and gravels are paved and compressed.
The technical scope of the present invention is not limited to the content in the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical spirit of the present invention, and these modifications and changes should fall within the protection scope of the present invention.
