Description

Technical Field

[0001] The present application relates to the field of municipal administration, and in particular to a road surface structure with an anti-jumping manhole cover. Background Art

[0002] There are many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet to the ground at intervals. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground, so a cover is needed. The cover used to cover the manhole is called a manhole cover (manhole cover). Manhole covers are usually made of reinforced cement, metal, reinforced plastic and other materials, and are mainly round and square in shape.

[0003] After a period of use, common manhole covers become unstable due to damage or loosening of the road surface around the manhole covers. When vehicles pass over the manhole covers, the manhole covers will bounce, causing loud noises. There are also certain safety hazards that need to be improved. Utility Model Content

[0004] In order to improve the problem of possible jumping of manhole covers, the present application provides a road surface structure with an anti-jumping manhole cover.

[0005] The present application provides a road surface structure with an anti-jumping manhole cover, which adopts the following technical solution:

[0006] A pavement structure with an anti-jumping manhole cover comprises a pavement and a manhole cover assembly arranged on the pavement, wherein a drain port and a drain channel are provided on the pavement, and the manhole cover assembly comprises a mounting frame and a cover body arranged on the mounting frame, wherein a mounting groove for mounting the mounting frame is provided at the drain port, and a mounting protrusion is provided on the mounting frame, wherein the mounting protrusion is accommodated in the mounting groove so that the mounting frame is accommodated at the drain port, and a ring width of the mounting protrusion is 3-5 cm; an abutting protrusion is provided on the mounting frame, wherein the abutting protrusion is abutted by the cover body, a locking block is provided at the bottom of the mounting frame, a locking groove is provided on the locking block, and a locking protrusion is provided at the bottom of the cover body, wherein the locking protrusion is accommodated in the locking groove so that the cover body is fixed to the mounting frame; and a sealing soil layer is provided on the pavement.

[0007] By adopting the above technical scheme, when installing the manhole cover structure, first dig an installation groove on the road surface, then place the installation frame in the installation groove, and then cover the installation frame. Finally, use a sealing layer (usually cement) to seal the gap between the installation frame and the road surface, thereby improving the installation stability of the installation frame, and smoothing the gap to make the road surface flat. Compared with common manhole covers, the manhole cover assembly consists of a mounting frame and a cover body. The mounting frame is installed in the mounting groove through mounting protrusions and fixed by cement sealing. The edge of the mounting frame is wider, and the impact force can be dispersed to the bottom and wall of the mounting groove when subjected to force, thereby reducing possible damage to the road surface, reducing road damage and potholes. The cover body is covered on the abutment protrusion to be fixed on the installation frame, and the movement of the manhole cover is limited by the cooperation of the locking protrusion and the locking groove, thereby improving the stability and firmness of the cover body. In addition, the mounting frame is stably installed, so the cover body will not jump when a vehicle passes by, thereby preventing the manhole cover from jumping when a vehicle passes by.

[0008] Optionally, an elastic pad is provided at the bottom of the installation frame, and the elastic pad abuts against the bottom of the installation groove.

[0009] By adopting the above technical solution, an elastic pad is set to absorb part of the impact force, which can disperse part of the impact force to reduce the impact force on the installation groove wall and the installation groove bottom, and reduce damage to the connection between the road surface and the manhole cover assembly.

[0010] Optionally, a limiting protrusion is provided at the bottom of the installation groove, and a limiting groove for accommodating the limiting protrusion is opened on the installation frame.

[0011] By adopting the above technical solution, the limiting protrusions and the limiting grooves are provided to position the installation frame during installation and prevent the installation frame from moving.

[0012] Optionally, an anti-falling net is provided in the sewer channel, and the anti-falling net is located directly below the cover body; the anti-falling net is a metal anti-falling net.

[0013] By adopting the above technical solution, an anti-fall net is set to prevent people from falling into the sewer channel when the cover is lost or damaged. The anti-fall net made of metal can withstand greater pressure and can stably support and protect people if they fall.

[0014] Optionally, three mounting blocks are provided on the side wall of the sewer channel, and the three mounting blocks are arranged at equal intervals along the side wall of the sewer channel; three connecting protrusions are provided on the anti-fall net, and the connecting protrusions are arranged corresponding to the mounting blocks, and the mounting blocks are provided with connecting grooves for accommodating the connecting protrusions.

[0015] By adopting the above technical solution, a mounting block is provided to accommodate the connecting protrusion, so that the anti-falling net can be fixed on the mounting block to be installed on the side wall of the sewer channel.

[0016] Optionally, the top surface of the cover body is provided with an anti-slip protrusion.

[0017] By adopting the above technical solution, the anti-skid protrusions are provided to increase the friction force applied to the vehicle when passing over the cover body, thereby reducing the possibility of the vehicle skidding.

[0018] Optionally, a water discharge hole is provided on the cover body.

[0019] By adopting the above technical solution, a drainage hole is provided to allow rainwater to flow into the drainage channel for drainage.

[0020] Optionally, a removal protrusion is provided on the inner wall of the drain hole.

[0021] By adopting the above technical solution, the removal protrusion is provided to facilitate maintenance personnel to remove the cover body.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The manhole cover assembly consists of a mounting frame and a cover body. The mounting frame is installed in the mounting groove through the mounting protrusion and fixed by cement plugging. The edge of the mounting frame is wide, and the impact force can be dispersed to the bottom and wall of the mounting groove when subjected to force, thereby reducing possible damage to the road surface, reducing road damage and potholes. The cover body is covered on the abutment protrusion to be fixed on the mounting frame, and the movement of the manhole cover is limited by the cooperation of the locking protrusion and the locking groove, thereby improving the stability and firmness of the cover body. In addition, the mounting frame is stably installed, so the cover body will not jump when a vehicle passes by, thereby preventing the manhole cover from jumping when a vehicle passes by;

[0024] 2. Set up elastic pads to absorb part of the impact force, which can disperse part of the impact force to reduce the impact force on the installation groove wall and the installation groove bottom, and reduce the damage to the connection between the road surface and the manhole cover assembly;

[0025] 3. Set up an anti-fall net to prevent people from falling into the sewer channel when the cover is lost or damaged. The anti-fall net made of metal can withstand greater pressure and can safely support and protect people if they fall. BRIEF DESCRIPTION OF THE DRAWINGS
