Simultaneously, because second side 61 and fourth side 63 are convex to the profile 600 outside, therefore, the extrusion force is inboard towards profile 600, the extrusion force can form the support to second side 61 and fourth side 63 in the footpath of second side 61 and fourth side 63, thereby the power of transmission on keeping off first side 60, make whole profile 600 of spool 6 remain stable, the condition of deformation is avoided appearing, the hidden danger in gap has probably appeared between spool 6 has been eliminated, can realize waterproofly effectively, prevent the effect of mud seepage, the waterproof performance and the intensity of spool 6 have been promoted, ensure that the pipeline system that whole spool 6 arranged is safe and reliable more.

Adopt above-mentioned technical scheme, through each side with the spool smooth connection in proper order to with second side and fourth side design for molding to the convex curve in the profile outside, not only dispersion that can be fine and bear the resultant force that the concrete was applyed, promote the intensity and the waterproof performance of spool, make the spool safe and reliable more, design second side and fourth side for the curve molding can make the pipeline better laminate with second side and fourth side in addition, promote the inside space utilization of spool.

It should be noted that, the utility model discloses do not restrict the concrete shape of first side and third side, can carry out reasonable selection according to actual need, as long as can guarantee intensity, waterproof performance and the intraductal space utilization of spool.

Specifically, referring to fig. 7-8, in the present embodiment, the first side edge 60 and the third side edge 62 are straight. By setting the first side 60 and the third side 62 as straight lines, not only the spool 6 can be made structurally simpler, facilitating production, transportation and installation, while ensuring sufficient strength and waterproof performance. Moreover, the high utilization rate of the internal space of the line pipe 6 can be ensured under the condition of certain height requirement.

Referring to fig. 9, in another embodiment of the present invention, the first side 60 and the third side 62 are curves protruding outward from the contour 600, and the curvatures K1 and K3 of the first side 60 and the third side 62 are less than 0.002, that is, the curvatures K1 and K3 at each point of the first side 60 and the third side 62 are less than 0.002. By also designing the first side 60 and the third side 62 as curves protruding outside the outline 600, not only can the connection between each side of the spool 6 be smoother, better disperse and bear the force applied by the concrete and ensure that the spool 6 has sufficient strength and waterproof performance, but also can increase the space inside the spool 6, and improve the threading capacity and the internal space utilization ratio of the spool 6. In addition, by limiting the curvatures K1, K3 at each point of the first side 60 and the third side 62 to less than 0.002, the degree of curvature of the first side 60 and the third side 62 can be limited, ensuring that the height of the conduit 6 is maintained within an effective range of use.

What further need explain, the utility model discloses do not restrict the concrete shape of second side and fourth side, can carry out reasonable selection according to actual need, as long as can guarantee intensity, waterproof performance and the intraductal space utilization of spool.

Specifically, in the present invention, the second side 61 and the fourth side 63 each include any one of an arc, an elliptical arc, a parabolic segment, a gradually-opened segment, and a spiral segment, or any combination thereof. In the present embodiment, the second side 61 and the fourth side 63 have the same shape, so that the stress of the conduit 6 can be distributed symmetrically, and preferably, the second side 61 and the fourth side 63 are both elliptical arcs. In other embodiments, the second side and the fourth side may have other shapes, which is not limited by the present invention.

Further, referring to fig. 9, in the present embodiment, the curvatures K2 and K4 of the second side 61 and the fourth side 63 range from 0.01 to 0.05, that is, the curvatures K2 and K4 at each point of the second side 61 and the fourth side 63 range from 0.01 to 0.05. When the curvatures K2 and K4 of the second side 61 and the fourth side 63 are large, the second side 61 and the fourth side 63 are protruded toward the outer side of the outline 600, so that the shapes of the second side 61 and the fourth side 63 become flatter, pipelines cannot be effectively arranged on two sides, and the space utilization rate inside the line pipe 6 is reduced. When the curvatures K2 and K4 of the second side 61 and the fourth side 63 are small, the second side 61 and the fourth side 63 become more straight, so that the smooth transition between the second side 61 and the fourth side 63 and the first side 60 and the third side 62 is increased, the force applied by concrete cannot be effectively dispersed and borne, and the strength and the waterproof performance of the conduit 6 are reduced. Therefore, preferably, the curvatures K2 and K4 of the second side 61 and the fourth side 63 range from 0.01 to 0.05, and the curvature of the second side 61 and the fourth side 63 is limited, so that the line pipe 6 can effectively disperse the force applied by the concrete, prevent the line pipe 6 from deforming, and further ensure that the line pipe 6 has high strength and good waterproof performance under the condition of ensuring that the inside of the line pipe 6 has high space utilization rate.

In the actual use process, certain limitation is imposed on the thickness of the poured concrete and the size of the steel reinforcement frame structure, and the thickness of the concrete is generally 80mm-150mm, so that certain limitation needs to be imposed on the size of the conduit to ensure that the conduit can be completely poured in the concrete and the steel reinforcement frame structure.

Specifically, referring to fig. 8 to 9, in the present embodiment, the distance L1 between the first side 60 and the third side 62 is 25mm to 45mm, that is, the maximum distance L1 between the first side 60 and the third side 62 is 25mm to 45 mm. The distance L2 between the second side 61 and the fourth side 63 ranges from 50mm to 300mm, i.e. the maximum distance L2 between the second side 61 and the fourth side 63 ranges from 50mm to 300 mm. Through the restriction to spool 6 size, can make spool 6 pour in concrete and steel framework structure completely, avoid spool 6 to expose from concrete and steel framework structure.

In addition, in order to maintain a high space utilization ratio inside the conduit, referring to fig. 8 to 9, in the present embodiment, the ratio of the distance between the first side 60 and the third side 62 to the distance between the second side 61 and the fourth side 63 ranges from 0.1 to 0.7. That is, the line pipe 6 needs to satisfy a certain ratio range in the height direction and the width direction, and preferably, this ratio range is 0.1 to 0.7, that is, the range of L1/L2 is 0.1 to 0.7. If the ratio of the height of spool 6 and width is less, can make the first side 60 and the length overlength of third side 62 of spool 6, its ability of bearing concrete pressure will reduce, produce the deformation easily, if the ratio of the height of spool 6 and width is great, can make the length overlength of second side 61 and fourth side 63 of spool 6, increased the height of spool 6, can't ensure that spool 6 can pour completely in the concrete, and reduced the inside space utilization of spool 6. In this embodiment, the range of L1/L2 is limited to 0.1-0.7, so that the space utilization rate inside the conduit 6 can be improved on the premise of ensuring the strength of the conduit 6.

Referring to fig. 7 to 9, in the present embodiment, the line pipe 6 is integrally formed of an aluminum alloy material. Through processing into the spool with aluminum alloy material integrated into one piece, not only can guarantee 6 overall structure's of spool leakproofness, promote spool 6 waterproof performance, aluminum alloy material can make the spool have better rust-resistant effect of corroding moreover, improves the life of spool. And the aluminum alloy material is easy to form and convenient to process and manufacture. Meanwhile, the aluminum alloy material can conduct electricity, can be used as a grounding wire of a pipeline system, and does not need to be provided with a grounding terminal and a grounding wire in the pipeline system separately, so that the structure of the pipeline system is simplified.
