Description

Technical Field

[0001] This utility model relates to the field of municipal road engineering technology, and in particular to a municipal sidewalk. Background Technology

[0002] As an important component of urban infrastructure, the durability and safety of municipal sidewalks directly affect the travel experience of citizens. Sidewalks are road spaces specifically for pedestrians, separated from the roadway by curbs, guardrails, and other facilities. As a key component of the urban road system, they are widely distributed along both sides of various urban streets.

[0003] Traditional sidewalk construction uses cast-in-place concrete, and its core process includes: first, compacting the foundation and laying a graded crushed stone base layer to ensure the foundation's bearing capacity meets standards; then, laying a crisscrossing steel mesh with a spacing of 150-200mm as a bending-resistant skeleton; next, pouring concrete to cover the steel reinforcement layer, and after vibration compaction, roughening or texturing the surface to enhance slip resistance; finally, implementing 7 days of standard curing, and cutting contraction joints at 4-6m intervals with a depth of 1 / 3 of the slab thickness to release temperature stress.

[0004] Regarding the aforementioned technologies, since sidewalks are exposed to the outdoor environment for extended periods, the high temperatures in summer cause the concrete slabs to expand thermally, and continuous exposure to sunlight can easily lead to cracks in the pavement. This not only affects the safety of pedestrians but may also cause accidents. The inventors believe there is a need to provide a crack-resistant municipal sidewalk. Utility Model Content

[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0039] This application discloses an embodiment of a municipal sidewalk. (Refer to...) Figure 1 and Figure 2 A municipal sidewalk includes a base 1, multiple rows of paving units 2 arranged longitudinally side-by-side on the base 1, and a first filling layer 3 disposed between adjacent paving units 2. Each paving unit 2 includes multiple paving blocks 21 arranged laterally at intervals, paving bricks 4 disposed on the top surface of each paving block 21, and a second filling layer 23 disposed between the paving blocks 21. The paving blocks 21 are cast-in-place concrete blocks, and the first and second filling layers 3 can be filled with asphalt. In this embodiment, each paving unit 2 contains six paving blocks 21, and the paving bricks 4 are arranged in a one-to-one correspondence with the paving blocks 21, with the number of paving bricks 4 also being six.

[0040] Reference Figure 2 and Figure 3 The laying unit 2 is provided with a first support pipe 22 running horizontally through it. The laying block 21 has a first through hole running horizontally through it for the first support pipe 22 to be arranged. The laying block 21 is pre-embedded in a first pre-embedded pipe 211 running horizontally through it, and the first through hole is arranged in the first pre-embedded pipe 211. The function of the first through hole is to allow the first support pipe 22 to pass smoothly through the laying block 21, thus providing lateral support for the laying unit 2. The first pre-embedded pipe 211 of the laying block 21 can be formed by placing the first pre-embedded pipe 211 in the concrete mold during the pouring of the laying block 21, and the first through hole is formed after the concrete solidifies. The diameter of the first through hole must match the first support pipe 22 to ensure that the first support pipe 22 can pass through tightly. In this embodiment, the first support pipe 22 is made of carbon steel, and the first pre-embedded pipe 211 is a rigid plastic pipe.

[0041] Reference Figure 2 and Figure 5The first embedded pipe 211 has a first sealing ring groove 2111 at its end, and a first sealing ring 2112 is arranged within the first sealing ring groove 2111. The first sealing ring 2112 is circumferentially sealed to the first support pipe 22. The sealing ring groove 2111 provides an installation position for the first sealing ring 2112, which is made of rubber. The circumferential sealing between the first sealing ring 2112 and the first support pipe 22 effectively prevents moisture and debris from entering the gap between the first support pipe 22 and the first embedded pipe 211, improving the structural sealing performance and service life.

[0042] Reference Figure 3 and Figure 5 Both ends of the first support tube 22 are provided with first sealing end caps 221. Each first sealing end cap 221 has a first mounting portion 2211 that is threaded into the first support tube 22. The first sealing end cap 221 also has a first vent hole 2212 penetrating its inner and outer surfaces. The first sealing end cap 221 is made of the same rigid material as the first support tube 22. The function of the first sealing end cap 221 is to further protect the ends of the first support tube 22 and prevent external impurities from entering. The threaded mounting portion 2211 facilitates the installation and removal of the first sealing end cap 221. The vent hole 2212 helps balance the air pressure inside and outside the first support tube 22, reducing damage caused by air pressure changes.

[0043] Reference Figure 3 and Figure 6 In adjacent paving units 2, the corresponding paving blocks 21 are arranged at intervals along the longitudinal direction. The municipal sidewalk is also equipped with a second support pipe 24 that runs longitudinally through the paving blocks 21 in the same row. The longitudinally spaced paving blocks 21 provide space for the installation of the second support pipe 24. The second support pipe 24 runs longitudinally through the paving blocks 21 in the same row, further enhancing the longitudinal stability of the sidewalk.

[0044] Reference Figure 6 and Figure 7 The laying block 21 has a second through hole that runs longitudinally through the laying block 21 and is used for the arrangement of the second support pipe 24. A second embedded pipe 25 that runs longitudinally through the laying block 21 is pre-embedded, and the second through hole is arranged in the second embedded pipe 25. The function and requirements of the second through hole are similar to those of the first through hole, ensuring that the second support pipe 24 can smoothly pass through the laying block 21. The second embedded pipe 25 can also be pre-reserved during the fabrication of the laying block 21.

[0045] Reference Figure 6 and Figure 7The second embedded pipe 25 has a second sealing ring groove 251 at its end, and a second sealing ring 2511 is arranged within the sealing ring groove 252. The second sealing ring 2511 is circumferentially sealed to the second support pipe 24. The second sealing ring groove 251 provides an installation position for the second sealing ring 2511. The second sealing ring 2511 is made of rubber and has good elasticity and sealing performance. Through the circumferential sealing cooperation between the second sealing ring 2511 and the second support pipe 24, the entry of moisture and debris into the gap between the second support pipe 24 and the second embedded pipe 25 can be effectively reduced, improving the structural sealing performance and service life.

[0046] Reference Figure 6 and Figure 7 The second support tube 24 has a second sealing end cap 241 at both ends. The second sealing end cap 241 has a second mounting portion 2411 that is threaded into the second support tube 24, and also has a second vent hole 2412 penetrating its inner and outer surfaces. The function of the second sealing end cap 241 is to further protect the ends of the second support tube 24 and prevent external impurities from entering. The threaded mounting portion 2411 facilitates the installation and removal of the second sealing end cap 241. The vent hole 2412 helps balance the air pressure inside and outside the second support tube 24, preventing damage caused by pressure changes.

[0047] Reference Figure 8 The foundation 1 is also equipped with embedded steel bars 11 corresponding to the paving blocks 21. Each paving block 21 has embedded steel pipes 27 corresponding to the embedded steel bars 11 and penetrating its upper and lower surfaces. The combined use of the embedded steel bars 11 and embedded steel pipes 27 enhances the connection strength between the paving blocks 21 and the foundation 1. The embedded steel bars 11 are usually pre-embedded during the construction of the foundation 1, and their length and diameter are determined according to the actual situation. The embedded steel pipes 27 are pre-embedded during the fabrication of the paving blocks 21. When the paving blocks 21 are placed on the foundation 1, the embedded steel bars 11 are inserted into the embedded steel pipes 27, and then fixed together by pouring concrete, making the paving blocks 21 and the foundation 1 form a whole, thus improving the stability of the sidewalk.

[0048] The implementation principle of a municipal sidewalk according to an embodiment of this application is as follows: A municipal sidewalk includes a foundation 1, paving blocks 21 arranged in a rectangular array on the foundation 1, and a filling layer between adjacent paving blocks 21. By setting two through pipes, one horizontal and one vertical, in the paving blocks 21, the probability of sidewalk cracking can be effectively reduced.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
