The outer shell 101 can significantly enhance the structural strength of the first assembly 1 and improve the structural stability of the road surface. In addition, in this embodiment, a plurality of reinforcing rib grooves 13 are opened upward from the bottom of the first assembly 1, and the reinforcing rib grooves 13 can further improve the structural strength of the first assembly 1.

[0035] The first assembly body 1 is provided with water guide grooves 11 on the side walls thereof. Rainwater penetrating downward from the road surface can be effectively discharged to both sides of the road through the water guide grooves 11, thereby effectively avoiding problems such as water accumulation on the road surface.

[0036] During specific implementation, the shell 101 is made of Q355B10mm steel plate to form a cuboid structure, which is 2000mm long, 1500mm wide and 300mm high. The bottom surface is made into a trapezoidal protrusion along the length as a reinforcing rib groove 13, the trapezoid is 150mm wide at the bottom, 50mm wide at the top and 50mm high, the trapezoidal protrusion is set 150mm away from the edge, and the rest is 200mm apart. The sides are made into a trapezoidal groove in the middle position as a water guide groove 11, the trapezoid is 100mm wide at the bottom, 60mm wide at the top and 20mm high. An 80mm flange 1011 is set on each side of the shell 101, and the ends of the flange 1011 are bent downward by 32mm to form a buckle edge 1012.

[0037] The first plate body 102 can be a rectangular parallelepiped structure cast using C30 steel fiber concrete, with a length of 2000 mm, a width of 1500 mm, and a height of 300 mm. A reinforcing steel cage 103 is arranged inside the first plate body 102, and the reinforcing steel cage 103 is composed of three-level 18 steel bars in double rows and two directions, and three-level 8@300 as hooks. A U-shaped first anchor bar 22 made of a first-level 20 steel bar is arranged at a position 350 mm away from the frame. The surface layer of the first plate body 102 is finished.

[0038] A plurality of first threaded holes 2 for hoisting are provided on the top surface of the first assembly 1. Specifically, a first anchoring rib 22 is pre-embedded in the first plate body 102, and a first threaded sleeve 21 is fixedly connected to the first anchoring rib 22. The upper port of the first threaded sleeve 21 is arranged flush with the top surface of the first plate body 102 to form the first threaded hole 2. The first anchoring rib 22 can be U-shaped or T-shaped. The cooperation between the first anchoring rib 22 and the first threaded sleeve 21 can improve the hoisting structural strength and hoisting stability of the first assembly 1. In addition, the first anchoring rib 22 and the first threaded sleeve 21 are pre-embedded in the first assembly 1, and there is no need to temporarily open a hoisting hole during hoisting, which is more convenient to use and improves construction efficiency.

[0039] Specifically, when the first anchor bar 22 is U-shaped, a U-shaped structure with a length of 800 mm and a height of 210 mm can be made using a grade 20 steel bar. A nut or a straight threaded sleeve (i.e., the first threaded sleeve 21) with a length of 40 mm and an inner diameter of 20 mm is welded at the top of the U-shaped structure.

[0040] When the first anchor bar 22 is T-shaped, a 20-diameter steel bar of the first grade can be used to make a T-shaped structure, which is 200 mm long and 130 mm high. A nut or a straight threaded sleeve (i.e., the first threaded sleeve 21) with a length of 40 mm and an inner diameter of 20 mm is welded to the top of the T-shaped structure.

[0041] The second assembly 3 includes a second plate body cast by steel fiber concrete and designed in a U shape. The opening of the second plate body is provided with a tongue-and-groove groove 31 matched with the rain grate 5 on both sides. The tongue-and-groove groove 31 cooperates with the rain grate 5 to improve the installation stability of the rain grate 5. A plurality of second threaded holes 4 for hoisting are provided at the upper opening of the second plate body. Specifically, a second anchoring rib 42 is vertically provided in the second plate body, and a second threaded sleeve 41 is fixedly connected to the upper end of the second anchoring rib 42. The upper end of the second threaded sleeve 41 is flush with the bottom surface of the tongue-and-groove groove 31 to form a second threaded hole 4. In this embodiment, the second anchoring rib 42 is U-shaped. The second anchoring rib 42 cooperates with the second threaded sleeve 41 to improve the hoisting structural strength and hoisting stability of the second assembly 3, and the second threaded hole 4 can be directly used for hoisting connection without drilling additional holes, which significantly improves the hoisting convenience of the second assembly 3.

[0042] In specific implementation, the second assembly block can be cast using C30 steel fiber concrete, and its U-shaped groove structure is 1000 mm long and 600 mm high, and an 8@150 steel cage 103 is matched and arranged inside.

[0043] The second anchor bar 42 and the second threaded sleeve 41 can be made of a 16mm diameter steel bar into a U-shaped structure and welded with a nut or a straight threaded sleeve with an inner diameter of 16mm, and placed 200mm away from the end of the U-shaped groove structure.

[0044] The U-shaped groove of the second assembly 3 is provided with a 50*50mm groove 31 at both ends, which is used to place the rainwater grate 5 later. The width and depth of the groove 31 are both 5mm. In addition, in this embodiment, a 100mm diameter round hole 32 is provided at a position 500mm from the end and 250mm from the top of the U-shaped groove structure of the second assembly 3.

In this design, the outer shell 101 is made of Q355B steel plate and is formed into a rectangular structure (2000mm long, 1500mm wide, and 250mm high). The bottom steel plate thickness is 20mm, and the thickness of the steel plates in other parts is 10mm. Trapezoidal grooves are made on the sides at a position 50mm away from the bottom as water guide grooves 11. The trapezoid is 100mm wide at the bottom, 60mm wide at the top, and 20mm high. The top steel plate is provided with holes of 200mm in length and 150mm in width at four positions 365mm away from the long side and 295mm away from the short side. In this embodiment, the first anchor bar 22 of the T-shaped structure made of a grade 20 steel bar in diameter can be installed in the first plate body 102 at a position 295mm away from its short side and 365mm away from its long side.
