[0038] Embodiment:

[0039] Figure 1 is a composite manhole cover based on mineral materials and carbon fiber cloth, including a manhole cover body and three layers of strengthening members provided inside the manhole cover body. Figure 2 is Figure 1 a schematic diagram of the strengthening members inside. Figure 3 is Figure 2Side view of Figure 4 is Figure 2 a three-dimensional schematic diagram of Figure 5 a schematic diagram of reinforcing ribs. The reinforcing member includes a plurality of reinforcing ribs 10, and the reinforcing ribs 10 of adjacent layers are perpendicular. A three-layer planar perpendicular structure is formed, which can enhance the strength.

[0040] Positive spiral grooves 11 and reverse spiral grooves 12 are formed on the reinforcing ribs 10, and carbon fiber cloths are wound around both the positive spiral grooves 11 and the reverse spiral grooves 12; the reinforcing ribs 10 are made of rock-based polymer materials, and the manhole cover body is made of rock-based polymer materials. Carbon fiber cloths are wound in the two spiral grooves. The carbon fiber cloths can resist tension and seismic reinforcement, increase the load-bearing capacity of the manhole cover, prevent material aging, and have low cost. The reinforcing ribs 10 and the manhole cover body are made of mineral materials, with low cost, high load-bearing capacity, and good corrosion resistance.

[0041] As Figure 5 shown, the positive spiral grooves 11 and the reverse spiral grooves 12 intersect multiple times, and the carbon fiber cloths are stacked at the intersections. Further, the two carbon fiber cloths are wound around each other at the intersections and then extend and lay along the spiral grooves respectively. The carbon fiber cloths are wound around each other once at each intersection to further enhance the strength.

[0042] The positive spiral grooves 11 and the reverse spiral grooves 12 have the same spiral angle, so that the laying methods and angles of the positive and reverse carbon fiber cloths are the same, and the load capacity is uniform.

[0043] The starting points and ending points of the positive spiral grooves 11 and the reverse spiral grooves 12 are the same, and fixing holes 13 are provided at the starting points and ending points; the two ends of the carbon fiber cloth wound in the positive spiral grooves 11 and the carbon fiber cloth wound in the reverse spiral grooves 12 are fixed in the fixing holes 13. The carbon fiber cloth is fixed in the fixing holes 13 by means of bolts, tying knots, etc.

[0044] The positive spiral grooves 11 and the reverse spiral grooves 12 each include a first side surface 14, a second side surface 15, and a bottom surface 16 located between the first side surface 14 and the second side surface 15. In a cross-section, the three surfaces form an isosceles trapezoid structure, so that the strength is uniform and the load capacity is uniform.

[0045] The length of the reinforcing ribs 10 is greater than the lengths of the positive spiral grooves 11 and the reverse spiral grooves 12, and the midpoints coincide. Thus, both ends of the reinforcing ribs 10 are in a blank state without winding the reinforcing ribs 10, which is convenient for fixing the carbon fiber cloth.

[0046] The lengths of the reinforcing ribs 10 in the same layer are different, which is matched with the circular structure design of the manhole cover.

[0047] In this embodiment, as Figure 3As shown, the reinforcing ribs 10 of adjacent layers do not contact each other, and are connected by casting with mineral materials.

[0048] In another embodiment, the reinforcing ribs 10 of adjacent layers contact each other, so that the three-layer reinforcing member is an integral whole with better strength. Figure 6 Shown is a schematic diagram of another reinforcing member. The positive spiral groove 11 and the negative spiral groove 12 form a first region 17 and a second region 18 on the surface of the reinforcing rib 10. A first hole 19 is provided in the first region 17 located in the middle layer, and a second hole 20 is provided in the second region 18 located in the middle layer. The centerlines of the first hole 19 and the second hole 20 are perpendicular to the centerline of the reinforcing rib 10. One of the reinforcing ribs 10 located in the outer layer is sequentially inserted into the first hole 19 located in the middle layer, and the other reinforcing rib 10 located in the outer layer is sequentially inserted into the second hole 20 located in the middle layer.

[0049] In this embodiment, a first hole 19 and a second hole 20 are provided in the reinforcing rib in the middle layer, which are respectively used to install the upper reinforcing member and the lower reinforcing member.

[0050] The diameter sizes of the reinforcing ribs 10 of the upper reinforcing member and the lower reinforcing member are smaller than the diameter size of the reinforcing rib 10 of the middle layer, and the diameter sizes of the first hole 19 and the second hole 20 are slightly larger than the diameter sizes of the reinforcing ribs 10 of the upper reinforcing member and the lower reinforcing member. The reinforcing ribs of the upper and lower layers are thinner, which can reduce the thickness of the entire manhole cover. The reinforcing ribs are provided on both sides, which can improve the strength of the manhole cover, so that both the strength requirements and the thickness requirements are met.

[0051] Furthermore, each of the reinforcing ribs 10 in the middle layer is provided with n first holes 19 and n - 1 second holes 20. The upper reinforcing member includes n reinforcing ribs 10, which are respectively installed in the n first holes 19, and the lower reinforcing member includes n - 1 reinforcing ribs 10, which are respectively installed in the n - 1 second holes 20. In this embodiment, there are 5 reinforcing ribs 10 in the middle layer, 3 reinforcing ribs 10 in the upper layer, and 2 reinforcing ribs 10 in the lower layer. The reinforcing ribs of the upper and lower layers are parallel.
