[0024] Example 1: like Figure 1-2 The specific steps of the nighttime dangerous rock treatment construction method include: 1) An access road is arranged at the top of the unstable rock mass, and excavation is carried out layer by layer from top to bottom. After the slope of each step is supported, construction area 1 is formed, and then the construction of the lower step is carried out. 2) Install guardrail 2 at a distance of 1.5 to 2 meters from the edge line on the outer side of construction area 1; 3) A warning barrier 3 shall be installed 1 to 1.5m inside the guardrail; 4) The guardrail 2 and the warning railing 3 form a gap, which serves as the unloading port 4; 5) Install wheel chocks 5 with a height of 1 to 1.5 m at 4 unloading ports; 6) After the blasted material excavated by the excavator is transported to the barrier 5 by the dump truck 6, the blasted material is unloaded onto the collection platform 7.

[0025] In a preferred embodiment, the material collection platform 7 is provided with a retaining wall 8, which is used to prevent stones from rolling off.

[0026] In the preferred embodiment, during step 6), the reversing and unloading operations of the dump truck 6 are carried out by on-site command by construction personnel equipped with infrared flashlights during the transfer of blasting materials.

[0027] Example 2: like Figure 3-6In the construction protection device based on the nighttime dangerous rock treatment construction method described in Example 1, there are guardrails 2 and warning railings 3. The guardrails 2 include baffles 9. A fixed post 10 is provided on one side of the baffles near both ends, and a reflective strip 21 is provided on the other side of the baffles 9. The warning barrier 3 also includes a baffle 9. One side of the baffle 9 is provided with a fixed post 10 near both ends, and the other side of the baffle 9 is provided with multiple horizontal light strips 13, which are fixed by light strip fixing buckles 14.

[0028] In a preferred embodiment, the two ends of the protective railing 2 and the warning railing 3 are respectively provided with a connecting groove 11 and a connecting protrusion 12; The two adjacent guardrails 2 or warning railings 3 are connected by a connecting groove 11 and a connecting protrusion 12.

[0029] In a preferred embodiment, the connecting grooves 11 and connecting protrusions 12 at both ends of the warning rail 3 are provided with contact points 15, and the contact points 15 at both ends of the warning rail 3 are respectively connected to the two ends of the light strip 13 provided on the warning rail 3.

[0030] In this example, the disclosed light strip 13 circuit is connected in series when installed. It is preferable to connect the light strips 13 on different warning barriers 3 in parallel to the main circuit. If a circuit fault occurs at a certain point, the fault location can be quickly found without affecting the operation of other light strips 13, ensuring the smooth progress of construction.

[0031] Example 3: Based on Example 2, such as Figure 8 In the process, the baffle 9 is composed of two plates, which are hinged together by a pin 16.

[0032] Since the outer edge of construction area 1 has an uncertain and irregular shape, the combined hinged structure in this example can effectively ensure that guardrail 2 and warning railing 3 are arranged along the outer edge of construction area 1, thus playing a good warning role.

[0033] Example 4: Based on Example 2, such as Figure 7 In the process, the fixed post 10 passes through the hoop 17 provided on the guardrail 2 and the warning railing 3. The hoop 17 is fixed to the guardrail 2 and the warning railing 3 by the connecting plate 20 and bolts. A single fixed post 10 passes through two hoop 17 located in the same vertical position.

[0034] In a preferred embodiment, among the two members 17 through which the single fixed column 10 passes, the upper member 17 is provided with a diagonal brace 18 and an extension plate 19, and the lower end of the diagonal brace 18 is fixed to the extension plate 19.

[0035] The above structure solves the problem of the difficulty in erecting the baffle 9 on soft soil. The stability of the baffle 9 can be ensured by the diagonal bracing 18 and the extension plate 19.

[0036] By adopting the above-mentioned protective device structure and construction method, the blasting and excavation of dangerous rocks under low visibility conditions can be carried out smoothly, and the construction safety at night or in rainy and foggy weather can be guaranteed.
