Description
Technical Field
The utility model discloses a buffer unit for stone calamity is prevented rolling by shed tunnel belongs to construction safety protection technical field.
Technical Field
In western mountainous regions of China, a lot of geological disasters such as landslide, rock rolling, collapse and the like are easy to occur. The adoption of a shed tunnel structure is one of the most effective active measures for preventing rock rolling disasters.
The top of the existing shed tunnel structure is a concrete slab structure, and in order to prevent the damage of the rolling stones to the shed tunnel, a cushion layer material with a certain thickness is usually covered on a concrete slab at the top of the shed tunnel. So as to reduce the influence of the impact load of the rolling stones on the shed tunnel. However, the conventional cushion layer has limited energy consumption buffering capacity.
SUMMERY OF THE UTILITY MODEL
The utility model provides a buffer unit for shed hole rolling stone calamity to can the effective absorption rolling stone impact energy, increase buffering power consumption effect improves the security level to shed hole protection, ensures construction safety, thereby overcomes prior art's not enough.
The technical scheme of the utility model as follows:
the utility model discloses a buffer unit for stone calamity is prevented rolling by shed tunnel, including last rubber slab and lower rubber slab, be equipped with a set of spring between last rubber slab and the lower rubber slab, in the space between spring and spring, it has polyurethane foam to fill.
In the buffer unit, the upper rubber plate and the lower rubber plate are both square rubber plates.
In the buffering unit, the bottom end of the spring is bonded with the lower rubber plate, and the top of the spring is bonded with the upper rubber plate.
In the buffer unit, the surface of the joint of the spring and the rubber plate is subjected to sand blasting treatment.
Since the technical scheme is used, the utility model discloses a buffer unit effective absorption rolling stone impact energy, increase buffering power consumption ability. The safety level of protection to the shed tunnel is improved, and the construction safety is ensured. The utility model discloses a buffer unit light in weight, the construction of being convenient for.

Description of reference numerals: 1-upper rubber plate; 2-lower rubber plate, 3-spring, 4-polyurethane foam, 5-shed tunnel, 6-concrete plate, 7-buffer unit and 8-gravel soil layer.
Detailed Description
The following further illustrates the invention with reference to the drawings and examples, but not as a limitation to the invention.
The utility model discloses a buffer unit for stone calamity is prevented rolling by shed tunnel, as shown in fig. 1, including last rubber slab 1 and lower rubber slab 2, be equipped with a set of spring 3 between last rubber slab 1 and lower rubber slab 2, in the space between spring 3 and spring 3, it has polyurethane foam 4 to fill. The upper rubber plate 1 and the lower rubber plate 2 are both square rubber plates. The bottom end of the spring 3 is bonded with the lower rubber plate 2, and the top of the spring 3 is bonded with the upper rubber plate 1. The surface of the joint of the spring 3 and the rubber plate is subjected to sand blasting treatment.
In particular, the application is as shown in fig. 1. After the buffering unit 7 of the utility model is laid on the concrete slab 6 at the top of the shed 5, a gravel soil layer 8 is covered on the buffering unit 7; the impact energy of the rolling stones on the concrete slab 6 at the top of the shed tunnel 7 is absorbed through the buffer unit 7, and the damage of the rolling stones on the shed tunnel 5 is prevented. The buffer unit 7 is a cubic block structure mass-produced by a specialized factory.
The utility model discloses a buffer unit effective absorption rubble impact energy, increase buffering power consumption ability. The safety level of protection to the shed tunnel is improved, and the construction safety is ensured. The utility model discloses a buffer unit light in weight, the construction of being convenient for.
