Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline protection, and in particular relates to a spliced road pipeline protection shell. Background Art

[0002] Municipal roads are roads that connect various areas of the city and are used for transportation and pedestrians within the city. They are convenient for residents' lives, work, cultural and entertainment activities, and are connected to roads outside the city to carry external traffic. Urban roads are generally wider than highways. In order to adapt to complex transportation, they are often divided into motor vehicle lanes, bus priority lanes, non-motor vehicle lanes, etc. There are sidewalks and houses on both sides of the road that are higher than the road surface. Public pipelines are often buried under the sidewalks. Green belts and sculptures are arranged to beautify the city. In order to protect the city's environmental sanitation, less dust and noise are required. Highways have shoulders outside the carriageway, street trees are planted on both sides, and side ditches are used for drainage. When laying pipelines, they are generally placed under the road. Due to the importance of pipeline laying, a protective casing is required for the pipeline.

[0003] A Chinese patent with announcement number CN221171051U discloses a spliced municipal road pipeline protective shell, including a concrete layer and an upper protective shell. The concrete layer has an installation groove, a placement seat is provided in the installation groove, and a placement groove is provided on the top surface of the placement seat. The placement groove contacts the lower protective shell, and a buffer pad is provided in the lower protective shell. The buffer pad contacts the pipeline, and a plurality of limit rods are fixed to the top surface of the lower protective shell. A plurality of through holes are provided on the top surface of the buffer pad. The limit rods pass through the through holes, and a threaded groove is provided on the top surface of the limit rods.

[0004] However, during the actual use of the pipeline protective shell in the above-mentioned prior art, we found that there are still some technical deficiencies. For example, multiple upper protective shells are arranged on the lower protective shell, which can be disassembled according to the damaged position of the upper protective shell. Since there are gaps between the multiple upper protective shells on the lower protective shell, it is easy for ground water to penetrate between the upper protective shell and the lower protective shell, causing the accumulated water to corrode the pipeline. Secondly, there is a lack of splicing structure between the lower protective shells, which makes the connection between the two lower protective shells not compact enough during docking. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a spliced road pipeline protective shell to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A spliced road pipe protective shell, comprising a lower protective shell and an upper protective shell, wherein the left end of the lower protective shell is fixedly connected to a first connecting block, an inner side of the first connecting block is provided with a first connecting hole, a right end bottom of the lower protective shell is provided with a first connecting groove, an inner side of the first connecting groove is fixedly installed with a first connecting column, a left end of the lower protective shell is provided with a second connecting groove, an inner side of the second connecting groove is fixedly installed with a second connecting column, a right end of the lower protective shell is fixedly connected to a second connecting block, an inner side of the second connecting block is provided with a second connecting hole, an upper end of the lower protective shell is fixedly installed with the upper protective shell through a fixing mechanism, and an inner side of the lower protective shell is provided with a drainage mechanism;

[0008] The drainage mechanism includes a drainage groove, which is provided at the inner bottom of the lower protective shell. Drain holes are symmetrically provided on the inner side of the drainage groove. A drainage pipe is fixedly installed at one end of the opening of the drainage hole. The drainage pipe is L-shaped. A metal mesh is threadedly installed at one end of the drainage pipe away from the drainage hole. Through the drainage mechanism, the protective shell of the pipeline can be easily drained to prevent internal water accumulation from damaging the pipeline;

[0009] The fixing mechanism includes a countersunk hole, a fixing bolt and a screw sleeve. The screw sleeve is fixedly installed on the upper end of the lower protective shell. The upper protective shell is plugged into the countersunk hole and the screw sleeve. The upper protective shell is threadedly connected to the screw sleeve through the fixing bolt passing through the countersunk hole. A rubber cover is movably connected to the inner side of the countersunk hole. The fixing mechanism can facilitate the connection between the upper protective shell and the lower protective shell.

[0010] As an optimal technical solution, a circular groove is provided at the opening of the drainage hole away from the drainage groove. The end of the drainage pipe away from the metal mesh is fixedly connected to a pipe seat. The drainage pipe is fixedly installed on the inner side of the circular groove through the pipe seat. The upper end of the drainage pipe is connected to the drainage hole through the pipe seat. The drainage pipe and the drainage hole can be conveniently installed and connected through the circular groove and the pipe seat.

[0011] As an optimal technical solution, the upper end of the upper protective shell is fixedly connected to a connecting seat, and a handle is welded to the upper end of the connecting seat. The handle can be used to easily remove the upper protective shell from the lower protective shell when disassembling it.

[0012] As an optimal technical solution, the concave arc portion at the lower end of the upper protective shell is fixedly connected with a first reinforcing plate at equal intervals, and the second reinforcing plate is fixedly connected between the adjacent first reinforcing plates at the concave arc portion at the lower end of the upper protective shell. The concave arc portion at the lower end of the upper protective shell is respectively provided with a first assembly groove and a second assembly groove. The first reinforcing plate is arranged on the inner side of the first assembly groove, and the second reinforcing plate is arranged on the inner side of the second assembly groove. The compressive strength of the upper protective shell can be improved by the first reinforcing plate and the second reinforcing plate.

[0013] As a preferred technical solution, the position of the first connecting block corresponds to the position of the first connecting groove, and the position of the second connecting groove corresponds to the position of the second connecting block. By making the positions of the first connecting block and the first connecting groove correspond, and the positions of the second connecting groove and the second connecting block correspond, the two lower protective shells can be conveniently spliced and used.

[0014] In summary, the present invention has the following beneficial effects:

[0015] First, plug the first connecting groove at the right end of one of the lower protective shells into the first connecting block at the left end of the other lower protective shell. During the plugging process, the first connecting column in the first connecting groove of one of the lower protective shells is plugged into the first connecting hole on the first connecting block of the other lower protective shell. At the same time, the second connecting block with the second connecting hole corresponding to the upper half of one of the lower protective shells is plugged into the second connecting groove with the second connecting column on the other lower protective shell. Then, by installing the corresponding upper protective shell and lower protective shell, the second connecting block can be limited in the second connecting groove, so that the two lower protective shells can be conveniently spliced and combined for use;

[0016] Second, when ground seepage water enters through the gaps between the upper protective shells, the seepage water seeps down along the inner wall of the lower protective shell into the drainage groove. At the same time, the seepage water is discharged from the drainage holes on both sides along the drainage groove and discharged to the outside through the drainage pipe, thereby avoiding water accumulation inside the lower protective shell and causing corrosion damage to the pipe. At the same time, a metal mesh is added to the lower end of the drainage pipe to prevent debris such as mud, sand and earthworms from entering during use;

[0017] Third, position the upper protective shell on the screw sleeve through the countersunk hole, then place the fixing bolts through the countersunk hole, and then fix it with the screw sleeve through the fixing bolts. This can facilitate the installation of the upper and lower protective shells, and add a rubber cover at the opening of the countersunk hole. The rubber cover is sealed at the countersunk hole by extrusion, which can reduce the oxidation and corrosion of the fixing bolts to a certain extent, making it convenient for the subsequent disassembly and replacement of the upper protective shell.
