[0002] In municipal construction, such as at the position of a station platform, there is a situation where the width of the station is relatively narrow. Because the curb needs to avoid the manhole well, it needs to be arranged around the side of the manhole well to form a square frame, resulting in a gap on the road surface. In places with a large flow of people at the station, it affects the walking of pedestrians and is not aesthetically pleasing.

[0003] After retrieval, in the prior art, there is a combined curb with a publication number of CN207331403U, which includes a bridge plate and bridge columns. The bridge plate is erected on the bridge columns, and the curb is installed on the bridge plate. When the curb has to avoid the manhole well, the curb is erected above the manhole well to cross the manhole well. When the road surface is uneven, the bridge columns cannot be adjusted, resulting in unevenness. At the same time, when it is arranged above the manhole well, when the manhole well needs to be repaired later, the entire device needs to be lifted and moved to one side, which is not convenient enough.

[0004] After retrieval, in the prior art, there is a paving cover plate and its curb structure for solving the conflict between the manhole well and the curb with a publication number of CN216006476U. During the construction of this device, first, a concrete foundation is poured at a suitable position below the sidewalk surface. At the same time, placing steps for placing the cover plate installation frame are opened on the curbs on both sides of the manhole well cover. Then, one end of the cover plate installation frame with anchor bars is placed on the concrete foundation, so that the anchor bars at the bottom of the cover plate installation frame are buried in the concrete foundation, and the other end of the cover plate installation frame is placed on the placing steps of the curb. After the cover plate installation frame is fixed on the concrete foundation, the cover plate body is laid into the cover plate installation frame. It requires the cooperation of concrete anchor bars, the production is not convenient enough, the setting time is long, the production difficulty is large, and it can only be considered completed after cooling and solidifying later.

[0005] According to the prior art, it is found that the bridge crossing device has inconvenient movement, consumes a large amount of manpower when the manhole well to be avoided needs to open the manhole well cover later, cannot make adaptive adjustments according to the actual ground flatness, and the installation completion time is long. Therefore, a new bridge crossing device for a curb that cannot avoid a manhole wellhead is proposed to solve the above problems. Summary of the Invention

The inspection well 3 is located on the road, and the curbstone 1 corresponding to the road is laid avoiding the inspection well 3. The curbstone 1 is arranged avoiding the inspection well 3 to form a square frame. Inside the square frame is provided a bridge crossing device 2. The bridge crossing device 2 includes: a support frame body 24 is arranged inside the square frame for placing and supporting the stone slab for pedestrians to walk on (such as Figure 1 and Figure 2 As shown, the bridge crossing device 2 is in Figure 1The baffle at the upper end with patterns for distinction is a stone slab. The stone slab can be made of the same material or stripes as the surrounding curb 1 to maintain consistency and enhance aesthetics. There is a square frame at the upper end of the bracket frame 24 to limit the lateral movement of the stone slab 4. Anchor bolts 21 are provided on the side of the bracket frame 24 to fix the bracket frame 24 on the curb 1. A sliding and flipping assembly 22 is provided on the side of the bracket frame 24 to drive the bracket frame 24 to flip. Legs 26 are provided at the lower end of the bracket frame 24 to support the stability of the bracket frame 24. An assisting component 23 is provided on the bracket frame 24 to assist in lifting the bracket frame 24.

[0037] Combined with Figure 4 、 Figure 5 and Figure 6 As shown, the assisting component 23 includes a limiting block 231 and a fixing sleeve 236. The fixing sleeve 236 is installed on the bracket frame 24. A rotating cylinder 234 is inserted into the middle of the fixing sleeve 236. There is also a limiting block 231 on the fixing sleeve 236, and the limiting block 231 is located at the upper end of the rotating cylinder 234. A threaded column provided at the lower end of the rotating cylinder 234 is threadedly connected to a threaded cylinder 235. The threaded cylinder 235 is placed in a cylinder provided at the lower end of the fixing sleeve 236. A long strip is provided on the outside of the threaded cylinder 235 for sliding cooperation with the cylinder to prevent the threaded column from driving the threaded cylinder 235 to rotate synchronously.

A buckle is provided at the rear end of the protective net 25, and the buckle is clamped with the leg 26. Slots are provided on both sides of the upper part of the protective net 25 for the staff to hold the support frame body 24, facilitating the pulling of the support frame body 24 and preparing for later maintenance.

[0040] Combined Figure 7 with Figure 8 As shown, in an embodiment, the leg 26 includes a support column 261 and a support cylinder 262. Support columns 261 are provided at the four corners of the lower end of the support frame body 24. The support column 261 is in threaded plug connection with the support cylinder 262. By rotating the support cylinder 262, the support cylinder 262 moves longitudinally on the support column 261, changing the total length of the two, and adjusting the length of the leg 26 according to the terrain.

[0041] Working principle: First, observe the flatness near the inspection well 3 to determine the length of the leg 26 to prevent the bridge device 2 from being unstable when the road surface is uneven. Then, on both sides of the inspection well 3, a sliding groove 11 is opened by a grooving machine (the model of the grooving machine can be preferably Dongcheng ZIR-FF-135, and the stone grooving machine is well-known to those skilled in the art and will not be elaborated here again). It is in sliding fit with the connecting column 223. At the same time, holes are drilled outside the sliding groove 11 and are matched with the anchor bolts 21. The support frame body 24 is placed into the square frame of the curbstone 1, and the anchor bolts 21 are inserted into the support frame body 24 and extended into the openings of the curbstone 1 to fix the support frame body 24. At the same time, pin holes are provided outside the anchor bolts 21 for inserting pin bolts. When the anchor bolts 21 are connected with the support frame body 24, a stone slab similar to the material of the curbstone is placed at the upper end of the support frame body 24 to fill the square frame where the inspection well 3 appears, reducing the situation of affecting the pedestrian flow at the station platform where the width of the sidewalk is compressed to avoid the inspection well 3Ⅱ and causing people to fall due to potholes.

[0042] When the inspection well 3 needs to be opened for operation, the staff can insert the sliding and flipping assembly 22 into the sliding groove 11, then pull out the anti-theft pin bolt on the anchor bolt 21 and pull out the anchor bolt 21. Pull the support frame body 24 outward through the slots on the protective net 25. At this time, the connecting column 223 moves horizontally in the sliding groove 11. Pull it to a suitable distance where the support frame body 24 can be rotated, and rotate the support frame body 24 to an angle that does not affect the opening and closing of the inspection well 3 cover for later maintenance operations.
