First buttress 4 and second buttress 5 are provided with first removal structure and second removal structure on the bottom surface with ground contact, and first removal structure and second removal structure set up to and track 6 joint according to the mode that can drive the support holder and follow track 6 steady movement to in the cross road support holder along moving towards a certain direction along track 6 under the direction of track 6. Through the arrangement mode, the cross road support does not need to be detached immediately after being used at one position, and can move along the guide direction of the track 6 through the first moving structure and the second moving structure, so that the cross road support can move to a proper position and then work. So as to ensure work efficiency.

According to a preferred embodiment, a stone foundation and sleepers are laid on the ground in contact with the buttresses, and the rails 6 are laid and fixed on the side of the sleepers remote from the ground.

Preferably, the rail 6 is provided as a rail 6 having a cross section similar to a "convex" shape, and a wider end of the rail 6 is connected to a sleeper so that the rail 6 is in close contact with the ground, thereby sufficiently securing the stability of the rail 6. The narrower end of the rail 6 is convex towards the side remote from the ground. Preferably, the moving wheel 7 is provided as an i-wheel in such a way as to increase the contact area with the rail 6 for deceleration. The two ends of the spool are wider and the middle of the spool is narrower, and the narrower middle of the spool is contacted with the bulge of the track 6. Under the condition that the middle part of the spool is contacted with the narrower end of the track 6, two ends of the spool are contacted with one side surface, far away from the ground, of the wider end of the track 6, so that the spool can be clamped with the track 6, the contact area of the spool and the track 6 is larger, and the friction force is larger when the spool needs to be fixed, so that the spool can be braked.

According to a preferred embodiment, the track 6 comprises at least a first section with a first coefficient of friction with the spool and a second section with a second coefficient of friction with the spool. The first coefficient of friction is smaller than the second coefficient of friction, i.e. the first section of the track 6 is smoother than the second section.

According to a preferred embodiment, two layers of square timber 13 are placed vertically and horizontally above the beam 12 to build a mobile platform for the constructors. The square timber 13 has high strength and light weight, can reduce the burden of the support bracket, and can provide a certain buffer function. A stable operation platform can be built for constructors. Preferably, the size of the square lumber 13 in the extending direction of the straddle-type frame may be set to 120mm × 150mm, for example; the dimension of the square lumber 13 perpendicular to the extending direction of the street crossing brackets may be set to 100mm × 120mm or 120mm × 150mm, for example.

The secondary connecting rod 16 has one end rotatably connected to the middle of the second rod 15 and the other end rotatably connected to the middle of the second rod 15. When the first rod 14 and the second rod 15 are relatively far away from each other, because one end of the first rod 14 is connected with the support, the second rod 15 gradually moves away from the first rod 14 towards the ground, the second rod 15 drives the secondary connecting rod 16 to be supported, and the second rod 15 is pushed to the direction far away from the support, so that a triangular stable supporting space is formed between the second rod 15 and the support, and stable supporting of the support is achieved.
