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. 3, in the present embodiment, the curvatures K2 and K4 of the second side 11 and the fourth side 13 range from 0.01 to 0.05, that is, the curvatures K2 and K4 at each point of the second side 11 and the fourth side 13 range from 0.01 to 0.05. When the curvatures K2 and K4 of the second side 11 and the fourth side 13 are large, the second side 11 and the fourth side 13 are protruded toward the outer side of the outline 100, so that the shapes of the second side 11 and the fourth side 13 become flatter, the pipelines cannot be effectively arranged on the two sides, and the space utilization rate inside the conduit 1 is reduced. When the curvatures K2 and K4 of the second side 11 and the fourth side 13 are small, the second side 11 and the fourth side 13 become more straight, so that the smooth transition between the second side 11 and the fourth side 13 and the first side 10 and the third side 12 is increased, the force applied by concrete cannot be effectively dispersed and borne, and the strength and the waterproof performance of the conduit 1 are reduced. Therefore, preferably, the curvatures K2 and K4 of the second side 11 and the fourth side 13 range from 0.01 to 0.05, and the curvature of the second side 11 and the fourth side 13 is limited, so that the line pipe 1 can effectively disperse the force applied by the concrete, the line pipe 1 is prevented from deforming, and the line pipe 1 can be further ensured to have higher strength and better waterproof performance under the condition of ensuring that the inside of the line pipe 1 has higher space utilization rate.

That is, the line pipe 1 needs to satisfy a certain ratio range in the height direction and the width direction, and preferably, the 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 1 and width is less, can make the length overlength of the first side 10 and the third side 12 of spool 1, its ability of bearing concrete pressure will reduce, produce easily and warp, if the ratio of the height of spool 1 and width is great, can make the length overlength of the second side 11 and the fourth side 13 of spool 1, increased the height of spool 1, can't ensure that spool 1 can pour completely in the concrete, and reduced the inside space utilization of spool 1. In this embodiment, the range of L1/L2 is limited to 0.1-0.7, so that the space utilization rate inside the conduit 1 can be improved on the premise of ensuring the strength of the conduit 1.

Referring to fig. 4 in conjunction with fig. 2 to 3, in the present embodiment, a ratio of an internal area S1 of the contour 100 to an area S2 of a minimum circumscribed rectangle T of the contour 100 is not less than 0.90, where the minimum circumscribed rectangle T is a rectangle located outside the contour 100, and each side of the rectangle is tangent to or coincides with a side of the contour, respectively, and the area of the rectangle is the minimum. Through the restriction to the ratio between the internal area S1 of the outline 100 and the area S2 of the minimum circumscribed rectangle T, the threading capacity of the line pipe 1 with the internal area S1 of the outline 100 is equivalent to the threading capacity of the rectangular line pipe with the section of the minimum circumscribed rectangle T, so that the internal space utilization rate of the line pipe 1 is kept high, the occupied space of the line pipe 1 is reduced, and the pouring of concrete is facilitated.
