Embodiment 1

[0044] Such as Figure 1-3 As shown, the present invention is a fabricated steel box shed suitable for emergency rescue and disaster relief, including a rectangular frame body 1 and a buffer armor 2. The rectangular frame body 1 is a protective channel structure with two ends openings prefabricated by section steel. The bottom frame 3 of the main body 1 is poured with a bottom plate 4 for pedestrians or vehicles to pass. The bottom plate 4 serves as a road for the protection passage. The top frame 5 of the rectangular frame body 1 and the side frame 6 on the side of the mountain are provided with Cushion armor 2. The top surface of the steel box shed and the side of the backer are equipped with a buffer energy dissipation device to make it the armor of the main structure. After falling rocks hit the buffer device, it can greatly reduce the impact force and protect the main structure. The buffer device allows Damaged and easy to replace. A plurality of steel pipe piles 7 anchor...

Embodiment 2

[0054] Such as Figure 1-3 As shown, a fabricated steel box shed construction method suitable for emergency rescue and disaster relief includes the following steps:

[0055] Step 1) Prefabricated rectangular frame main body 1 structure, rectangular frame main body 1 adopts welding or screw connection; install buffer armor 2 and buffer brace 13 outside the top frame 5 of rectangular frame main body 1 and the side frame 6 on the side of the mountain;

[0056] Step 2) Use mechanical equipment to clean up the obstacles on the section 1 where the rectangular frame body needs to be installed, and smooth the roadbed;

[0057] Step 3) According to the length of the road section where the rectangular frame body 1 needs to be installed, determine the set number of the rectangular frame body 1, and then use mechanical equipment to lift or push the assembled rectangular frame body 1 into place. The main body (1) of the segmented rectangular frame is connected by the connecting head 11 pin shaft...

Embodiment 3

[0062] Such as Figure 1-3 As shown, a fabricated steel box shed construction method suitable for emergency rescue and disaster relief includes the following steps:

[0063] Step 1. Prefabricate the structure of the rectangular frame body 1, and the rectangular frame body 1 is welded or screwed;

[0064] Step 2 Clean up the obstacles on the section of the main body 1 of the rectangular frame, and smooth the roadbed; mechanical equipment (forklift) can be used to clean up the obstacles and arrange the roadbed, and the safety of the construction personnel can be protected by mechanical equipment.

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

[0066] Step 4 According to the length of the road section where the rectangular frame body 1 needs to be installed, determine the number of rectangular frame bodies 1, and then lay the rectangular frame body 1 on the roadbed, and the adjacent rectangular frame bodies 1 ar...

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 a fabricated steel box shed suitable for emergency rescue and disaster relief and a construction method. It is especially suitable for the technical field of highway construction and construction after the occurrence of geological disasters such as landslides and high-level collapses. Background technique [0002] In recent years, the road damages following strong earthquakes in mountainous areas have shown that the secondary geological disasters such as landslides and high-level landslides have the greatest damage to the road, the most difficult to secure passage, and the most profound damage. [0003] Since the Wenchuan earthquake, technical countermeasures for high-level collapse have attracted great attention from all parties concerned. In the in-situ restoration and reconstruction, concrete shed holes or open tunnels are generally used, and the time is very ...
