Problems solved by technology

Traditional rolling stone sheds are mostly poured with fully reinforced concrete, so the construction speed is slow. At the same time, in order to prevent the impact damage of rolling stones, a layer of buffer energy dissipation cushion is generally covered on the rolling stone shed, which will inevitably increase the weight of the shed tunnel structure and increase the project size. invest

Embodiment Construction

[0018] figure 1 figure 2 It is shown that the present invention includes a rock shed tunnel frame 1 and a concrete shed tunnel slab 2 arranged on the light steel structure frame, and also has an energy dissipation shock absorber 3: left and right vertical plates 3c, 3d welded on the upper and lower horizontal The plates 3a and 3b are formed between the plates 3a and 3b, and the upper and lower horizontal plates are provided with bolt connection holes; a plurality of energy dissipation shock absorbers are connected between the rock shed cave frame 1 and the concrete shed cave plate 2 by bolts 4. The rolling stone shed cave frame 1 is an H-shaped steel structure frame of the rolling stone shed cave. The concrete shed hole slab 2 is a prefabricated C30 reinforced concrete slab.

[0019] Refer to the attached drawings, the rolling stone shed frame 1 is made of H-shaped steel, and (prefabricated C30) reinforced concrete shed slab 2 is arranged on it, and Q235B material is set between...

Abstract

The invention relates to an energy dissipation and vibration reduction rolling rock shed-tunnel structure with an assembled lightweight steel structure, which belongs to the protective structure used in the existing engineers of roads, railways and the like to prevent for preventing the collapse rolling rock disease. The energy dissipation and vibration reduction rolling rock shed-tunnel structure comprises a rolling rock shed-tunnel frame, a concrete shed-tunnel plate arranged on the rolling rock shed-tunnel frame and energy dissipation and vibration reduction devices. Left and right vertical boards are welded between upper and down transverse boards to form each energy dissipation and vibration reduction device. The upper and down transverse boards are provided with holes for connecting bolts. A plurality of energy dissipation and vibration reduction devices are connected between the rolling rock shed-tunnel frame and the concrete shed-tunnel plate by the bolts. The energy dissipation and vibration reduction rolling rock shed-tunnel structure with the assembled lightweight steel structure has the characteristics of safety, high efficiency, economy and simple construction.

Description

Technical field [0001] The invention relates to a new structure for preventing and controlling collapse and rolling stone disasters in linear projects such as highways and railways, in particular to a rolling stone disaster prevention structure consisting of a light steel frame and shock absorbers. Background technique [0002] Collapses and rockfalls are common roadbed diseases in mountain railways. In order to prevent and control such roadbed diseases, the railway public works department has established monitoring (installing alarm devices and setting up guards) and clearing (sweeping mountains on steep slopes to remove dangers) through long-term exploration and practice. Operational protection measures based on stone), support (retaining reinforcement, slope protection and wall protection), connection (wall connection fence), and fixation (bonding reinforcement, spray anchor closure); and shelter (open tunnel. Shed hole), protection (SNS soft net protection), circumvention (ch...
