The pressure plate 3-3 is connected to the center of the left side surface of the horizontal column 3-1. Several inserts 3-4 are evenly distributed around the perimeter of the left side surface of the pressure plate 3-3. The inserts 3-4 are inserted into the locking holes 1-4.

[0006] Reference Figures 1-4 The aforementioned highway widening construction device for high-altitude and cold regions is characterized by comprising: a pre-embedded device 1 and a connecting device 3 connected to the center of the right side surface of the pre-embedded device 1; a buffer metal 2 connecting the pre-embedded device 1 and the connecting device 3; a buffer rubber ring 4 connected to the periphery of the right side surface of the connecting device 3; a steel cage 5 inserted on the outer side of the center of the right side surface of the connecting device 3; a support device 6 inserted in the middle of the inside of the steel cage 5; and a fixing post 7 connected to the middle of the outer surface of the support device 6.

[0007] In use, first insert the pre-embedded device 1 into the old road surface side within the widened roadbed, then align the connecting column 3 with the pre-embedded device 1 and clamp the buffer metal 2 in the middle, then weld the pre-embedded device 1 and the connecting device 3 together, then insert the steel cage 5 into the connecting device 3 and lock it in place. When the steel cage 5 is inserted into the connecting device 3, the buffer rubber ring 4 can buffer the force of the steel cage 5 hitting the connecting device 3. Then, the worker holds the fixing column 7 and places the support device 6 inside the steel cage 5. At the same time, the frame on the steel cage 5 is locked inside the upper and lower surfaces of the connecting device 6. Finally, pour concrete into the foundation pit to submerge the steel cage 5.

[0008] Furthermore, the pre-embedded device 1 includes a top plate 1-1, a pin 1-2, barbs 1-3, and locking holes 1-4. The pin 1-2 is connected to the center of the right side surface of the top plate 1-1. Several barbs 1-3 are symmetrically connected in vertical rows on the left and right sides of the side surface of the pin 1-2. Several locking holes 1-4 are evenly distributed around the four edges of the left side surface of the top plate 1-1. The buffer metal 2 is located at the center of the right side surface of the top plate 1-1. The left end of the pin 1-2 is conical.

[0009] When using, insert the pin 1-2 into the old road surface side within the widened roadbed, while simultaneously securing the barbs 1-3 within the old road surface to prevent the pin 1-2 from being pulled out. Then, keep the top plate 1-1 at a certain distance from the side surface of the roadbed, ensuring it is not in close contact with the side surface of the roadbed.

[0010] Furthermore, the connecting device 3 includes a horizontal column 3-1, a barb 3-2, a pressure plate 3-3, and inserts 3-4. The barbs 3-2 are symmetrically connected vertically on the left side surface of the horizontal column 3-1. The pressure plate 3-3 is connected to the center of the left side surface of the horizontal column 3-1. Several inserts 3-4 are evenly distributed around the four edges of the left side surface of the pressure plate 3-3. The inserts 3-4 are inserted into the locking holes 1-4. The buffer metal 2 is disposed between the pressure plate 3-3 and the top plate 1-1. The horizontal column 3-1 is inserted into the steel cage 5, and the barbs 3-2 are locked onto the steel cage 5.

[0011] In use, first align the pressure plate 3-3 with the top plate 1-1 and clamp the buffer metal 2. At the same time, insert the insert 3-4 through the hole 1-4 and bend the insert 3-4 to clamp it on the left surface of the top plate 1-1. Then, use electric welding to weld the insert 3-4 to the top plate 1-1. Then, insert the steel cage 5 into the horizontal column 3-1 and hook the barb 3-2 onto the steel cage 5 to prevent the steel cage 5 from moving during pouring. Finally, pour the concrete into the foundation pit.

[0012] When there is a large temperature difference between winter and summer, the buffer metal 2 can buffer the compression and stretching of new and old road surfaces during thermal expansion and contraction.

[0013] Furthermore, the support device 6 includes a column 6-1, diagonal braces 6-2, a tray 6-3, and a groove 6-4. Several diagonal braces 6-2 are evenly distributed around the upper and lower edges of the outer surface of the column 6-1. The trays 6-3 are symmetrically connected at the center of the upper and lower surfaces of the column 6-1. Each tray 6-3 has a groove 6-4 at the center of its outer surface. The frame of the steel cage 5 is inserted into the groove 6-4. The diagonal braces 6-2 are triangular in shape.

[0014] When in use, the worker holds the fixed post 7 and places the post 6-1 inside the steel cage 5. At the same time, the frame on the steel cage 5 is inserted into the tray 6-3 and into the groove 6-4. Meanwhile, the diagonal bracing 6-2 supports the tray 6-3 to prevent deformation. The worker can insert a support device 6 at intervals according to the length of the steel cage to prevent the steel cage 5 from deforming during pouring.
