AI Technical Summary
After traditional manhole cover structures are installed on asphalt roads, the gaps between the supports and the road structure increase over time, causing the manhole cover structure to loosen, resulting in poor stability and safety, and easily leading to safety accidents.
The system employs both anchoring and spring mesh structures. The anchoring structure is secured to the concrete via U-shaped hooks, increasing the stability of the support. The spring mesh structure provides protection and cushioning to prevent pedestrians from falling.
It improves the stability and safety of manhole cover supports, preventing manhole covers from loosening and pedestrians from falling, especially ensuring safety on busy traffic routes.

TECHNICAL FIELD
[0001] The utility model belongs to the manhole cover technical field, especially relate to a cover plate ditch support structure. BACKGROUND
[0002] The manhole is the drainage structure arranged in the road, and a manhole cover structure is installed at the well mouth position, the main body structure of the manhole cover structure includes the support in the installation mouth of the lining on the road and the cover plate ditch covered on the support.According to the covering mode, it is mainly divided into hinged cover plate and directly covered cover plate.
[0003] Because the support of the manhole cover structure is mostly installed on the road (the slot structure is opened on the road and matched with the manhole cover support), therefore the stability of the manhole cover support is influenced by the stability of the road structure.
[0004] Specifically, the poured road is mostly poured with asphalt material, and the structural strength of the asphalt material is greatly reduced after a certain period of use (vehicle rolling), which causes the gap between the support and the road structure to gradually increase, and then the manhole cover structure is easy to loosen, which is reflected in: after the vehicle rolling or the pedestrian treading, the manhole cover structure shakes.
[0005] In serious cases, the manhole cover structure completely loses the support of the road structure, and then the stability and safety of the manhole cover structure cannot be guaranteed, therefore, if the pedestrian treads on the manhole cover, the manhole cover structure with poor stability and safety is easy to cause the pedestrian to fall from the well mouth position, and serious safety accidents are caused.
[0006] Therefore, for the traditional manhole cover structure, if the manhole cover structure and the road structure are not reinforced and stabilized, the stability and safety of the manhole cover structure, especially on the traffic artery with heavy traffic, the ordinary structure of the manhole cover structure cannot guarantee the safety.

[0037] Example 1
[0038] like Figures 1-5 As shown, a cover plate trench support structure includes a cover plate support mechanism, wherein the cover plate support mechanism includes a support, and a cover plate 2 is fitted onto the support.
[0039] Specifically, the structure of the support is as follows:
[0040] The support includes an outer annular protrusion 11, the top of which is integrally formed with a vertical annular protrusion 12 of a limiting cover plate, and the inner sidewall of the outer annular protrusion 11 is integrally formed with an inner annular protrusion 13 of a partition cover plate. The cover plate is fitted into the vertical annular protrusion 12, and its bottom is supported on the inner annular protrusion 13.
[0041] In the existing method, the bearing is lined within a slotted structure in the road (connecting to the manhole opening). To address the issue of road structure deformation caused by heavy vehicles, which reduces the stability between the bearing and the road slotted structure, several reinforcing structures are fixedly connected between the aforementioned vertical annular protrusion 12 and the outer annular protrusion 11. Several anchoring structures are fixedly connected to the reinforcing structures; the anchoring structures are used to increase the stability of the bearing.
[0042] Specifically, the reinforcing structure includes a triangular rib plate 4, the inner side of which is welded to the outer wall of the vertical annular protrusion 12; the bottom of the triangular rib plate 4 is welded to the top of the outer annular protrusion 11.
[0043] The above-mentioned anchoring structure includes several U-shaped hook tie bars 41 that are respectively fixedly connected to the triangular rib plate 4. The outer end of the U-shaped hook tie bar 41 is integrally formed with a hook part 411 with a bent hook.
[0044] Specifically, a pair of U-shaped hook ribs 41 are fixedly connected to the triangular rib plate 4, which are arranged vertically and horizontally. The hook part 411 of the U-shaped hook rib 41 at the upper position is bent upward, and the hook part 411 of the U-shaped hook rib 41 at the lower position is bent downward.
[0045] During construction, embedding slots are made on the inner wall of the road groove where the bearings are installed. After the bearings are installed, U-shaped hook ties 41 are placed into the embedding slots. Subsequently, concrete is poured on top. As the concrete sets, the U-shaped hook ties 41 are anchored in the embedding slots. Because the outer end of the U-shaped hook ties 41 has a hook, the anchoring effect between the hook and the concrete further increases the stability of the bearing. The circumferential anchoring of the circumferentially distributed U-shaped hook ties 41 further improves the stability of the entire bearing and the road structure. With this method, even after the road structure material is subjected to rolling deformation, the bearing can still maintain high stability.
[0046] Similarly, a number of U-shaped abutment mounting seats 31 that cooperate with the U-shaped hook tie 41 are fixedly installed on the top of the outer annular protrusion 11, and the U-shaped abutment mounting seats 31 are threaded with anchor bolts 32.
[0047] After the U-shaped hook tie bar 41 is anchored, the anchor bolt 32 is tightened into the road material layer (on the side wall of the groove structure on the road), forming a double anchoring effect and further improving the stability of the support.
[0048] Example 2
[0049] like Figures 1-5 As shown, based on the structure of Embodiment 1, in order to further improve the safety of the cover ditch support structure during use and solve the technical defect that the loose cover ditch support structure could cause pedestrians to fall, especially children, once a pedestrian steps on the cover, the above-mentioned cover ditch support structure also includes a lower net structure that can be detachably installed at the bottom of the outer annular protrusion 11. The lower net structure includes a net frame, and the bottom of the net frame is fixedly connected to an anti-fall net 6.
[0050] Specifically, the net frame includes an annular frame portion 5, the bottom of which is integrally formed with an annular protrusion 51, and the fall protection net 6 is a nylon net bag; the nylon net bag is fixedly connected to the bottom of the annular protrusion 51.
[0051] The detachable installation method is as follows: Several fastening bolts 71 are installed on the top of the annular frame part 5 (the bottom of the fastening bolts 71 is threadedly connected to a threaded tube seat, which is welded to the top of the annular frame part 5). Several mounting seats fastened to the fastening bolts 71 are fixedly connected to the bottom of the outer annular protrusion 5111. During operation, the fastening bolts 71 are tightened into the threaded grooves on the mounting seats to fix the space frame in place.
[0052] The fall protection net 6 increases safety when pedestrians, especially children, step on a loose cover ditch support structure and fall into it.
[0053] Example 3
[0054] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 2, several springs 7 are fixedly connected inside the aforementioned annular frame 5, forming a spring mesh structure. The spring mesh structure formed by the springs 7 provides further protection when the nylon material ages. Specifically, if a pedestrian falls in, the mesh structure formed by the springs 7 acts as a barrier, and the deformation of the springs provides further cushioning.
[0055] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
