Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel plate laying structure for municipal roads. Background Technique

[0002] Municipal pipeline construction can be seen everywhere and is closely related to people's lives. The biggest problem faced is how to safely minimize the impact of construction on people's lives to the greatest extent. Since municipal pipeline construction is located on municipal roads, especially in bustling areas, the construction has a great impact on traffic.

[0003] In the early days, municipal pipeline construction was carried out by large-scale excavation and enclosure construction, either closing half of the road or closing the whole section for detour; in recent years, non-excavation foundation pit enclosure construction has been carried out. Although it has greatly reduced the impact on traffic to a certain extent, with the acceleration of the urbanization process, it can no longer meet the current traffic and social needs of urban development; now, municipal pipeline construction has gradually developed into night construction, with steel plates covering during the day to ensure normal traffic, and basically minimizing the impact of construction on traffic. The main theme of development is to gradually reduce the impact of construction on the normal operation of the city. Then the stability and anti-slip of the steel plates covering the foundation pit, or the safety of the steel plates, is very important.

[0004] In the prior art, the surface of the steel plate is smooth. When it rains or the road is sprinkled with water, it becomes even smoother, which is likely to cause pedestrians and vehicles to skid and have accidents. Using anti-slip rubber pads is bulky, difficult to maintain, and the pads are likely to shift or roll up when vehicles pass, seriously affecting traffic and increasing the risk factors. The thickness of the steel plate itself forms a hard edge with the flat road surface, which is likely to cause pedestrians and bicycles to trip and seriously damage the tires of passing vehicles; at the same time, the impact of the vehicle on the steel plate is likely to cause the steel plate to shift, creating potential safety hazards. Content of the Utility Model

[0005] In order to achieve the above object, the utility model is realized through the following technical solutions:

[0006] A steel plate laying structure for municipal roads includes a steel plate body and a speed bump. The steel plate body is laid in the foundation pit on the road surface. Steel nails are fixedly connected to the four sides near the steel plate body in the foundation pit. Multiple steel nails limit the steel plate body in the foundation pit. A speed bump is jointly clamped on the upper parts of two adjacent steel nails. The speed bump is clamped on one side of the steel plate body. Bolts are installed at equal intervals along the length direction inside the speed bump, and the speed bump is fixedly connected to the foundation pit through the bolts.

[0007] Further preferably, the shape and size of the steel plate body are equal to those of the foundation pit, and the thickness of the steel plate body is equal to the depth of the foundation pit.

[0008] Further preferably, the bottom of the steel nail extends into the ground, and the height of the upper part of the steel nail is less than the thickness of the steel plate body.

[0009] Further preferably, a card slot corresponding to the position of the steel nail and having a matching size is provided at the bottom of the speed bump.

[0010] Further preferably, the height of the speed bump on the road surface is equal to the height of the steel plate body inside the foundation pit.

[0011] Further preferably, an anti-slip coating is provided on the steel plate body, and the material of the anti-slip coating is epoxy resin, quartz debris, and oil-based anti-slip paint.

[0012] Further preferably, the thickness of the steel plate body is 2.5 cm to 3.5 cm.

[0013] Compared with the prior art, the utility model has the following advantages: through the speed bumps arranged around the steel plate body, the steel plate body and the speed bumps form a gentle slope with the road surface, avoiding the harm of the hard edges of the steel plate body to pedestrians and vehicles, reducing the impact of the vehicle on the steel plate, reducing the harm of pedestrians and vehicles to the displacement of the steel plate body, and using steel nails to fix the steel plate body, improving the stability of the installation of the steel plate body, improving the passing efficiency of the construction section, and reducing the traffic safety risk.

[0017] The following further introduces the utility model in detail with reference to the attached Figures 1 to 2 drawings.

[0018] A steel plate laying structure for a municipal road, as Figure 1 shown, includes a steel plate body 1 and a speed bump 3. The steel plate body 1 is laid in a foundation pit on the road surface. Steel nails 2 are fixedly connected to the four sides of the foundation pit close to the steel plate body 1. The plurality of steel nails 2 limit the steel plate body 1 in the foundation pit. A speed bump 3 is jointly clamped on the upper parts of two adjacent steel nails 2. Further, the steel plate body 1 is laid around by the speed bump 3, so that the steel plate body 1 and the road surface form a gentle slope. The speed bump 3 is clamped on one side of the steel plate body 1. Bolts 4 are installed at equal intervals along the length direction inside the speed bump 3. The speed bump 3 is fixedly connected to the foundation pit through the bolts 4.

[0019] By means of the speed bumps 3 arranged around the steel plate body 1, the steel plate body 1 and the speed bumps 3 form a gentle slope with the road surface, avoiding the harm of the sharp edges of the steel plate body 1 to pedestrians and vehicles, reducing the impact of the vehicle on the steel plate, reducing the harm of pedestrians and vehicles to the displacement of the steel plate body 1, and using the steel nails 2 to fix the steel plate body 1, improving the stability of the installation of the steel plate body 1, improving the traffic efficiency of the construction section, and reducing the traffic safety risk.

[0020] Specifically, as Figure 2 shown, the shape and size of the steel plate body 1 are equal to those of the foundation pit, and the thickness of the steel plate body 1 is equal to the depth of the foundation pit. Further, when the steel plate body 1 is placed inside the foundation pit, the upper part of the foundation pit and the steel plate body 1 are on the same horizontal plane, further improving the traffic efficiency of the construction section and reducing the traffic safety risk.

[0021] Specifically, as Figure 2 shown, the bottom of the steel nail 2 extends into the ground, and the upper height of the steel nail 2 is less than the thickness of the steel plate body 1. Further, the steel nail 2 is used to fix the periphery of the steel plate body 1, effectively improving the stability of the fixed steel plate 1.

[0022] Specifically, as Figure 2 shown, the bottom of the speed bump 3 is provided with a card slot corresponding to the position of the steel nail 2 and having a size adapted thereto. Further, the bottom of the speed bump 3 is clamped on the foundation pit through the steel nail 2, and one side of the speed bump 3 is clamped on the steel plate body 1. Further still, the stability of the installation of the steel plate body 1 is improved.

[0023] Specifically, as Figure 2 shown, the height of the speed bump 3 on the road surface is equal to the height of the steel plate body 1 inside the foundation pit. Further, it reminds passing vehicles to slow down and pay attention to the construction area ahead, reducing the occurrence of traffic accidents. When the vehicle passes through the steel plate body 1, the speed bump 3 can reduce the bumping and impact of the vehicle, protecting the safety of the steel plate body 1 and the vehicle. The setting of the speed bump 3 can increase the friction between the steel plate body 1 and the ground, preventing the steel plate body 1 from displacing under the action of vehicle load.

[0024] Furthermore, select a steel plate body 1 with appropriate specifications and thickness to ensure that its load-bearing capacity meets the requirements. Before laying, sandblast and rust-remove the steel plate body 1 and apply an anti-slip coating. Further, sandblasting and rust-removing use compressed air to spray sand grains at high speed onto the steel plate surface, and remove rust, scale, and other contaminants through the impact and friction of the sand grains. Exemplarily, the temperature of the steel plate body 1 during sandblasting is controlled above 5°C to avoid cold brittleness caused by low temperature, and the relative humidity should not exceed 85% to prevent dew condensation on the steel plate surface from affecting the rust-removing effect. The sandblasting pressure is controlled between 0.4 and 0.6 MPa, with the criterion that the metal luster is exposed on the surface of the steel plate body 1 and there are no rust spots. After rust-removing, the surface of the steel plate body 1 should reach a certain cleanliness level (such as Sa2.5 grade) and roughness (such as 50 - 100 μm) to ensure good bonding between the coating and the steel plate body 1.

[0025] Further, through sandblasting and rust-removing treatment, the rust and contaminants on the surface of the steel plate body 1 can be removed, providing a good foundation for subsequent anti-slip painting treatment, increasing the surface roughness of the steel plate body 1, helping the painting material to adhere better, and extending the service life of the steel plate body 1 and the painting layer.

[0026] Further, the material of the anti-slip coating can be epoxy resin, quartz debris, and oil-based anti-slip paint. Exemplarily, the ratio of epoxy resin to quartz debris is 1:6. Further, the anti-slip paint is evenly applied by spraying or brushing to form an anti-slip surface layer to ensure the safe passage of pedestrians and vehicles.

[0027] Further, use appropriate tools to remove all sundries, stones, etc. inside the foundation pit. Further, trim the edge of the foundation pit to ensure that the slope and flatness of the edge meet the construction requirements for subsequent steel plate laying.

[0028] Working principle

[0029] Before use, pre-treat the surface of the steel plate body 1. Use compressed air to spray sand grains at high speed onto the steel plate surface, and remove rust, scale, and other contaminants through the impact and friction of the sand grains. Subsequently, evenly apply the anti-slip paint on the surface of the steel plate body 1 and wait for the anti-slip paint to dry. During use, use appropriate tools to remove all sundries, stones, etc. inside the foundation pit. Further, trim the edge of the foundation pit to ensure that the slope and flatness of the edge meet the construction requirements for subsequent steel plate laying. Place the steel plate body 1 in the cleaned foundation pit, fasten the steel nails 2 around the steel plate body 1, and then snap the speed bump 3 onto the steel nails 2, so that the speed bump 3 and the steel plate body 1 form a gentle slope with the road surface. Finally, use bolts 4 to fix the speed bump 3 to the ground to avoid the harm of the hard edges of the steel plate to pedestrians and vehicles. When construction is carried out, remove the bolts 4 so that the speed bump 3 is separated from the ground and the steel plate body 1, and then remove the steel plate body 1 to construct the foundation pit.

After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as they are within the protection scope of the utility model, they are protected by the Patent Law.
