Description

Technical Field

[0001] The utility model relates to a pipe laying technology, in particular to an HMPVC steel composite flame-retardant cable pipe. Background Art

[0002] Cable conduit is a type of conduit that meets the requirements of substation cable access and overhead line burial, and provides a power channel for the power supply of plots along the line. The outstanding features of cable conduit are high strength and low friction resistance. Generally, cable conduit is constructed in conjunction with road construction or municipal pipeline construction.

[0003] The existing cable conduit laying method generally involves first digging the road surface to form a trench, then laying the cable conduits in sequence, and finally backfilling the trench with earth or pouring concrete. The steps are cumbersome and the operation is complicated. The overall laying time is long, resulting in a long road occupancy time, which greatly affects the normal passage of vehicles and pedestrians. Utility Model Content

[0004] In order to solve the defects of the above-mentioned prior art, the utility model provides an HMPVC steel composite flame-retardant cable conduit, which can be laid quickly, improves laying efficiency, and reduces road occupancy time.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solution: an HMPVC steel composite flame-retardant cable conduit, comprising a column, wherein pipe grooves are evenly arranged inside the column, grooves are provided on both sides of the top of the column, and lifting ears are provided in the grooves.

[0006] Preferably, the vertical cross-section of the column is square.

[0007] Preferably, a cable pipe is provided in the pipe groove, and the cable pipe is a HMPVC power pipe.

[0008] Preferably, the length of the cable tube is the same as the length of the column.

[0009] Preferably, one end of the cable tube extends out of the tube groove, and the other end of the cable tube retracts into the tube groove.

[0010] Preferably, side limiting grooves are evenly distributed on the side walls of both sides of the column.

[0011] Preferably, the side limiting groove is a trapezoidal groove.

[0012] Preferably, positioning grooves are provided on both sides of the bottom of the column.

[0013] Preferably, the top surface of the lifting ear is not higher than the top surface of the column.

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

[0015] The HMPVC steel composite flame-retardant cable conduit of the utility model adopts prefabricated columns to form a pipe groove for setting the cable pipe, which can be quickly laid into the groove, greatly improving the laying efficiency. In the later stage, only a small amount of earth needs to be backfilled to restore the original appearance, which greatly shortens the road occupation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1:

[0027] like Figure 1 -3 shows an HMPVC steel composite flame-retardant cable conduit, comprising a column 1, wherein pipe grooves 2 are evenly arranged in the column 1, grooves 5 are provided on both sides of the top of the column 1, and lifting ears 6 are provided in the grooves 5; wherein the column 1 is an HMPVC steel composite finished column made of HMPVC steel composite flame-retardant material; two lifting ears 6 are provided, which not only improve the stability of the column 1 hoisting, but also provide the binding position of the winch rope when fine-tuning the horizontal position of the column 1.

[0028] The HMPVC steel composite flame-retardant cable conduit of this embodiment adopts a modular column 1 to form a pipe groove 2 for setting the cable pipe, which can be quickly laid into the groove, greatly improving the laying efficiency. In the later stage, only a small amount of earth needs to be backfilled to restore the original appearance, which greatly shortens the road occupation time.

[0029] The vertical cross section of the column 1 is square.

[0030] A cable pipe is provided in the pipe groove 2, and the cable pipe is an HMPVC power pipe; the length of the cable pipe is the same as the length of the column 1; one end of the cable pipe extends out of the pipe groove 2, and the other end of the cable pipe retracts into the pipe groove 2; this setting can facilitate the alignment of the front and rear columns 1.

[0031] Side limiting grooves 3 are evenly distributed on the side walls of both sides of the column 1; the side limiting grooves 3 are trapezoidal grooves, and the setting of the limiting grooves can facilitate the installation of the horizontal guiding device when fine-tuning the horizontal position.

[0032] Positioning grooves 4 are provided on both sides of the bottom of the column 1 .

[0033] The top surface of the lifting lug 6 is not higher than the top surface of the column 1 to prevent the gap between the upper and lower columns 1 from being too large and causing instability.
