Embodiment 1

[0044] like Figure 1-3As shown, the present invention is an assembled steel box shed suitable for emergency rescue and disaster relief, including a rectangular frame main body 1 and a buffer armor 2. The bottom frame 3 of the main body 1 is poured with a bottom plate 4 for pedestrians or vehicles to pass through, and the bottom plate 4 is used as the road surface of the protective passage. The top frame 5 of the rectangular frame main body 1 and the side frame 6 on the mountain side are equipped with Buffer armor 2. The top surface of the steel box shed and the side of the mountain are equipped with buffer energy-dissipating devices to make it the armor of the main structure. After falling rocks hit the buffer device, the impact force can be greatly reduced, thereby protecting the main structure. The buffer device allows broken, easy to replace. The bottom side of the bottom frame 3 of the rectangular frame main body 1 is uniformly arranged with a plurality of steel pipe pil...

Embodiment 2

[0054] like Figure 1-3 As shown, a construction method for a prefabricated steel box shed suitable for emergency rescue and disaster relief, including steps:

[0055] Step 1) Prefabricate the structure of the rectangular frame main body 1, the rectangular frame main body 1 is welded or screwed; the buffer armor 2 and the buffer strut 13 are installed outside the top frame 5 of the rectangular frame main body 1 and the side frame 6 on the mountain side;

[0056] Step 2) Use mechanical equipment to clean up the obstacles on the section 1 of the main body of the rectangular frame that needs to be installed, and level off the roadbed;

[0057] Step 3) Install the section length of the rectangular frame main body 1 according to the needs, determine the setting quantity of the rectangular frame main body 1, and then use mechanical equipment to lift or push each segment of the assembled rectangular frame main body 1 into place. The main body (1) of the segmental rectangular frame i...

Embodiment 3

[0062] like Figure 1-3 As shown, a construction method for a prefabricated steel box shed suitable for emergency rescue and disaster relief, including steps:

[0063] Step 1 Prefabricating the structure of the main body 1 of the rectangular frame, the main body 1 of the rectangular frame is welded or screwed;

[0064] Step 2: Clean up obstacles on section 1 of the main body of the rectangular frame, and level the roadbed; mechanical equipment (forklifts) can be used to clean up obstacles and tidy up the roadbed, and the safety of construction workers can be protected by mechanical equipment.

[0065] Step 3: Set anchor rods 7 evenly on the subgrade where the rectangular frame main body 1 needs to be installed;

[0066] Step 4 Install the section length of the rectangular frame main body 1 according to the needs, determine the setting quantity of the rectangular frame main body 1, then lay the rectangular frame main body 1 on the roadbed, and connect the adjacent rectangular ...

Abstract

The invention discloses an assembly type steel box shed tunnel suitable for emergency rescue and disaster relief and a construction method. The shed tunnel comprises a rectangular frame main body, buffer armors and a protection channel structure with openings at the two ends, a bottom plate for allowing pedestrians or vehicles to pass is laid on the inner wall of the bottom frame of the rectangular frame main body, the buffer armors are arranged outside the top frame of the rectangular frame main body and outside the side frame at the side, close to a hill, of the rectangular frame main body,and a plurality of steel pipe piles anchored on the roadbed are uniformly distributed on the bottom side of the bottom frame of the rectangular frame main body. The shed tunnel and the method solve the several key problems which can not be solved by a traditional steel shed tunnel with cross beams and stand columns for instance that the adaptability is poor, the impact resistance is poor, the requirement for the foundation is high, the construction period is long and the construction safety risk is high, and the shed tunnel is a brand new protection form.

Description

technical field [0001] The invention relates to the technical field of road traffic safety protection, in particular to an assembled steel box shed and a construction method suitable for emergency rescue and disaster relief. It is especially suitable for the technical field of construction and construction of highways after geological disasters such as landslides and high-level collapses occur. Background technique [0002] In recent years, the road damage after several strong earthquakes in mountainous areas shows that secondary geological disasters such as landslides and high-level collapses are the most damaging to roads, the most difficult to get through and maintain, and the most far-reaching damage. [0003] Since the Wenchuan Earthquake, the technical countermeasures to deal with high-level collapses have attracted great attention from all parties concerned. Concrete shed holes or open holes are generally used in in-situ restoration and reconstruction, but the time i...
