[0032] 40 protective body DETAILED DESCRIPTION

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] This embodiment proposes a road slope opening reinforcement device, such as Figure 1-4 As shown, the structure comprises a horizontally arranged base 10, side frames 20 symmetrically positioned above the base 10, a top frame 30 positioned on the upper end surfaces of the side frames 20 and fixedly connected to the side frames 20, and a protective body 40 positioned outside the side frames 20 and top frame 30. The cross-section of the space enclosed by the base 10, side frames 20, and top frame 30 is an isosceles trapezoidal structure, with the length and width of the top frame 30 both being smaller than those of the base 10. The side frames 20 are rectangular trapezoidal structures and are tilted toward the top frame 30, with the small sections of the side frames 20 positioned adjacent to the top frame 30. The top frame 30 is rectangular in structure, with its width matching the width of the small sections of the side frames 10. The structure of the protective body 40 matches the external structures of the side frames 20 and top frame 30.

[0035] like Figure 5 As shown, the length L1 of the foundation body 10 is greater than the width distance L2 between the outermost sides of adjacent side frames 20, and the width W1 of the foundation body 10 is greater than the maximum width W2 of a single side frame 20. The area of ​​the foundation body 10 needs to be determined based on the size of the roadside slope opening. The foundation body 10 is positioned on the ground at the roadside slope opening and is constructed of cast concrete. At least a portion of the width of the foundation body 10 is located inside the opening, and the top frame 30 must be completely positioned inside the opening. This ensures the reinforcement device's support strength for the interior of the opening, prevents earthwork inside the roadside slope opening from collapsing, and prevents personnel or machinery from being trapped inside the roadside slope opening. In this embodiment, the foundation body 10 is cast with C20 concrete to form a 150 mm thick concrete layer. During the concrete casting process, a mounting plate for fixing the lower end surface of the side frame 20 is embedded in the upper end surface of the foundation body 10. The mounting plate is composed of a steel plate with a thickness of at least 10 mm and M20 high-strength bolts. The area of ​​the mounting plate must be larger than the area of ​​the lower end surface of the side frame 20. The width from the outer edge of the foundation body 10 to the edge of the embedded mounting plate must be at least 10-20 cm.

[0036] like Figure 6As shown, the side frame 20 includes at least two parallel side beams 21, 22, and 3, that are arranged in parallel. That is, the side beams 21, 22, and 3 are arranged side by side. The side beams 21, 22, and 3 are arranged along the length of the foundation 10. The side beam 21 is arranged close to the width side of the foundation 10, and the side beams 22, 22, and 3 are both arranged close to the middle position in the length direction of the foundation 10. The upper section of the side beam 21 is inclined toward the middle position of the foundation 10, and the lower section is arranged close to the outer side of the foundation 10. Relative to the side beam 21, the side beam 22 is arranged obliquely downward, and the side beam 23 is arranged obliquely upward. The side beams 22 and 3 are both arranged on the side of the side beam 21 away from the protective body 23.

[0037] Furthermore, side beam No. 1 21, side beam No. 2 22, and side beam No. 3 23 are welded together to form two K-shaped support frames standing side by side. The top surfaces of side beam No. 1 21 and side beam No. 3 23 are welded and fixedly connected to the lower end surface of the top frame body 30. The lower end surfaces of side beam No. 1 21 and side beam No. 2 22 are fixedly mounted on the upper end surface of the infrastructure body 10. One end of side beam No. 2 22 of each group intersects with one end of side beam No. 3 23 and is fixedly mounted in the middle position of side beam No. 1 21. Moreover, side beam No. 1 21, side beam No. 2 22, and side beam No. 3 23 of each group are all located on the same plane. A side beam No. 4 24 is also provided between adjacent support frames, i.e., between the side beams No. 1 21 arranged side by side. The two ends of side beam No. 4 24 are respectively connected to the intersection of side beam No. 2 22 and side beam No. 3 23.

[0038] Furthermore, the side frame 20 also includes a No. 5 side beam 25, a No. 6 side beam 26 and a No. 7 side beam 27, wherein one end of the No. 5 side beam 25 is connected to the upper end portion of the No. 1 side beam 21 away from the length side of the foundation body 10, and the other end is fixed on the upper end surface of the foundation body 10; one end of the No. 6 side beam 26 is connected to the middle part of the No. 5 side beam 25, and the other end is connected to the lower end surface of the No. 1 side beam 21 close to the No. 5 side beam 25; one end of the No. 7 side beam 27 intersects with the upper end surface of the No. 5 side beam 25, and the other end is placed on the foundation body 10; the No. 5 side beam 25 is placed on the side of the foundation body 10 away from the top frame body 30 and the length of the No. 5 side beam 25 is greater than the length of the No. 1 side beam 21.

[0039] Furthermore, the lower end faces of the two No. 1 side beams 21 and the No. 5 side beam 25 are both located in the No. 1 longitudinal column; the lower end faces of the two No. 2 side beams 22 and the No. 7 side beam 27 are located in the No. 2 longitudinal column; the No. 1 longitudinal column and the No. 2 longitudinal column are parallel and are both arranged along the width direction of the infrastructure body 10.

[0040] like Figure 7As shown, the top frame body 30 includes a plurality of long top beams 31 and a plurality of short top beams 32 . The long top beams 31 and the short top beams 32 are vertically connected and at least both ends of the long top beams 31 are connected with the short top beams 32 .

[0041] In this embodiment, the side frames 20 and top frame 30 are both made of steel, such as channel steel, I-beam, square steel, or H-beam. Preferably, HW300×150b Q235B steel, commonly used in the construction industry, is used. The specific dimensions of the side frames 20 and top frame 30 will depend on actual working conditions and are not specifically limited herein.

[0042] The protective body 40 is a protective net, which is welded and fixed to the outer surface of the side frame body 20 and the top frame body 30. It is mainly used to protect large-sized stones or other debris. At the same time, it can also prevent the inner soil of the cave entrance from collapsing. Under the condition of ensuring the strength of the reinforcement device, it prevents foreign objects from clogging the cave entrance and ensures that the cave entrance road is unobstructed.
