Description

Technical Field

[0001] This utility model relates to the technical field of subway construction supporting equipment, and in particular to a sunken steel plate pavement for subway construction. Background Technology

[0002] Construction of subway station structures often conflicts with existing pipelines, necessitating the relocation of these pipelines outside the station structure to meet construction requirements. Pipeline relocation is a crucial component of the early stages of subway construction, involving numerous construction procedures.

[0003] During construction, there are many situations where construction crosses roads and intersections. Sometimes, when construction crosses roads, traffic cannot be restored in a short time. Moreover, subway projects are often located in bustling urban areas with high requirements for traffic. Therefore, we propose a sunken steel plate pavement for subway construction. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sunken steel plate pavement for subway construction.

[0005] This utility model is achieved using the following technical solution: a sunken steel plate pavement for subway construction, comprising a patterned plate, a steel plate fixedly connected to the bottom of the patterned plate, a rubber pad provided at the bottom of the steel plate, a first protrusion provided at one end of the patterned plate, a first groove provided at the end of the patterned plate away from the first protrusion, a first bolt threadedly connected to the inner wall of the first protrusion, a second protrusion provided at one end of the patterned plate, a second groove provided at the end of the patterned plate away from the second protrusion, and a second bolt threadedly connected to the inner wall of the second protrusion.

[0006] Through the above technical solutions, the sunken steel plate pavement has sufficient rigidity to avoid damage to the underlying pipelines and structures caused by traffic loads, eliminate safety hazards, and has a tight and smooth connection with the existing pavement. It also eliminates uneven settlement of paved pavement and misalignment of ground paving, and avoids collisions and scratches to pedestrians and vehicles.

[0007] As a further improvement to the above solution, the top of the steel plate is provided with threaded holes corresponding to the positions of the first bolt and the second bolt.

[0008] The above technical solution facilitates subsequent connection with the first and second bolts through the threaded hole opened on the top of the steel plate.

[0009] As a further improvement to the above solution, two of each of the first protrusion and the first groove are provided, and the sizes of the first protrusion and the first groove are matched.

[0010] As a further improvement to the above solution, the lower end of the first bolt passes through the first protrusion and is threadedly connected to the inner wall of the threaded hole.

[0011] With the above technical solution, when the first protruding block enters the interior of the first groove during splicing, the first bolt passes through the threaded hole corresponding to the first protruding block and the steel plate to connect, thereby installing and fixing the patterned plate, which facilitates flexible adjustment of the width according to the needs during construction.

[0012] As a further improvement to the above solution, two of each of the second groove and the second protrusion are provided.

[0013] The above technical solution uses the second groove to limit the second protrusion, which facilitates the subsequent installation of the second bolt.

[0014] As a further improvement to the above solution, the dimensions of the second groove and the second protrusion are matched.

[0015] As a further improvement to the above solution, the lower end of the second bolt passes through the second protrusion and is threadedly connected to the inner wall of the threaded hole.

[0016] With the above technical solution, after aligning the second protrusion, the two patterned plates are connected together by connecting the second bolt through the threaded hole corresponding to the inner wall of the steel plate, which makes it easy to flexibly adjust the required length according to the needs.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model incorporates a patterned plate, a steel plate, and a rubber pad. Specifically, the rubber pad is laid on the base surface, ensuring full coverage without any voids, which effectively reduces noise. The steel plate is then placed on top of the rubber pad to facilitate traffic. The patterned plate increases friction, preventing accidents to pedestrians and vehicles. The rubber pad under the steel plate provides a sturdy structure that is not easily damaged or deformed, requires no maintenance or replacement, and is recyclable. The recessed steel plate design is clean, aesthetically pleasing, safe, and reliable.

[0019] This utility model features a first protruding block, a first groove, a second groove, and a second protruding block. Specifically, when the patterned plate needs to be lengthened, the second protruding block on the other side of the patterned plate is placed inside the second groove, and then it is installed and fixed by the second protruding block, thus achieving the lengthening effect. This allows for flexible adjustment according to construction needs, and the modular design facilitates subsequent transportation. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-5 This embodiment describes a sunken steel plate pavement for subway construction, comprising a patterned plate 1, a steel plate 2 fixedly connected to the bottom of the patterned plate 1, a rubber pad 3 provided at the bottom of the steel plate 2, a first protrusion 4 at one end of the patterned plate 1, a first groove 5 at the end of the patterned plate 1 away from the first protrusion 4, a first bolt 6 threadedly connected to the inner wall of the first protrusion 4, a second protrusion 8 at one end of the patterned plate 1, a second groove 7 at the end of the patterned plate 1 away from the second protrusion 8, and a second bolt 9 threadedly connected to the inner wall of the second protrusion 8. First, the position of the steel plate 2 is measured and marked on-site, and the boundary of the steel plate 2 is marked with an ink line. A cutting machine is used to cut the asphalt along the ink line boundary, and a handheld electric pick is used to further refine the pavement. After chiseling and manually cleaning the edges and corners, a small tamping machine is used to compact the foundation. The foundation surface is then backfilled with mortar made of stone powder and cement to level the bottom surface of steel plate 2, ensuring close contact between the base surface, rubber pad 3, and steel plate 2. Over time, the mortar hardens and gains strength. Rubber pad 3 is then laid on the base surface, ensuring full coverage without voids, effectively reducing noise. Steel plate 2 is then placed on top of rubber pad 3 for convenient traffic. The patterned plate 1 increases friction, preventing accidents to pedestrians and vehicles. The rubber pad 3 under steel plate 2 provides a sturdy structure that is not easily damaged or deformed, requires no maintenance or replacement, and is recyclable. The sunken steel plate 2 design is clean, aesthetically pleasing, safe, and reliable.

[0030] The top of the steel plate 2 has threaded holes corresponding to the positions of the first bolt 6 and the second bolt 9.

[0031] There are two of each of the first protrusion 4 and the first groove 5. The sizes of the first protrusion 4 and the first groove 5 are matched. When it is necessary to widen the patterned plate 1, the first protrusion 4 on one side of the other patterned plate 1 is placed into the first groove 5, and then it is installed and fixed by the first bolt 6 to achieve the widening.

[0032] The lower end of the first bolt 6 passes through the first protrusion 4 and is threadedly connected to the inner wall of the threaded hole.

[0033] There are two of each of the second groove 7 and the second protrusion 8. When it is necessary to lengthen the patterned plate 1, the second protrusion 8 on the other side of the patterned plate 1 is placed inside the second groove 7, and then it is installed and fixed by the second protrusion 8 to achieve the lengthening.

[0034] The dimensions of the second groove 7 and the second protrusion 8 are matched.

[0035] The lower end of the second bolt 9 passes through the second protrusion 8 and is threadedly connected to the inner wall of the threaded hole.

[0036] The implementation principle of a sunken steel plate pavement for subway construction in this embodiment is as follows: First, the position of the steel plate 2 is measured and marked on-site. The boundary of the steel plate 2 is then marked with an ink line. A cutting machine is used to cut the asphalt along the ink line boundary. A handheld electric pick is used to chisel away the pavement. The edges and corners are cleaned manually. After chiseling, a small compactor is used to compact the foundation. The foundation surface is backfilled with mortar made of stone powder and cement to level the bottom surface of the steel plate 2, ensuring close contact between the base surface, rubber pad 3, and steel plate 2. Over time, the mortar hardens, forming a certain strength. Then, the rubber pad 3 is laid on the base surface, fully covering it without any voids, effectively reducing noise. Finally, the steel plate 2 is placed on the rubber pad 3 for easy handover. For smooth traffic flow, the patterned plate 1 increases friction, preventing accidents to pedestrians and vehicles. A rubber pad 3 is laid under the steel plate 2, ensuring a sturdy structure that is not easily damaged or deformed, requires no maintenance or replacement, and is recyclable. The recessed steel plate 2 is clean, aesthetically pleasing, safe, and reliable. When the patterned plate 1 needs to be widened, the first protrusion 4 on one side of another patterned plate 1 is placed inside the first groove 5, and then fixed with the first bolt 6. Similarly, when the patterned plate 1 needs to be lengthened, the second protrusion 8 on the other side of the patterned plate 1 is placed inside the second groove 7, and then fixed with the second protrusion 8. This modular design allows for flexible adjustments based on construction needs and facilitates subsequent transportation.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
