Roadbed edge protection device with noise reduction function for highway construction

Abstract

The invention discloses a roadbed edge protection device with a noise reduction function for highway construction. The roadbed edge protection device comprises a first combined protection main body, abuffer anti-collision plate, a second combined protection main body, a buffer frame, a small water pump, a mounting sleeve, a filter cover, a buffer spring and a transmission spiral shaft, and the first combined protection main body is combined and connected with the second combined protection main body through a connecting shaft fixedly mounted on the outer wall of one side of the first combinedprotection main body; according to the invention, an anti-collision mechanism is mounted on the outer part; a buffer rod of the anti-collision mechanism can directly relieve the impact force of collision; meanwhile, a part of impact force is also dispersed to a buffer spring in the mounting shell; the anti-collision mechanism can buffer impact force in the horizontal direction and the vertical direction at the same time, a good anti-collision effect is achieved, a fixing shaft with the extrusion spring is installed outside the anti-collision mechanism, if the anti-collision mechanism is damaged in the using process, the fixing shaft can be directly pulled down, taking and installing are convenient, the overall protection device does not need to be replaced, and the device is practical.

Description

technical field [0001] The invention belongs to the field of road construction, in particular to a roadbed edge protection device with noise reduction function for road construction. Background technique [0002] The subgrade is the foundation of the track or road surface, and it is a geotechnical structure formed after excavation or filling. The main function of the subgrade is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or trains, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and spread the load to the depth of the foundation. On the vertical section, the subgrade must ensure the elevation required by the line; on the plane, the subgrade is connected with bridges and tunnels to form a complete through-line. Therefore, in civil engineering, the subgrade occupies an important position in terms of construction quantity,...

Problems solved by technology

[0004] The purpose of the present invention is to provide a roadbed edge protection device with noise reduction function, to solve the problem that the roadbed proposed in the above background technology is a relatively important construction part in the construction of road engineering, in order to protect and isolate the roadbed, generally Some protective devices will be installed on the edge of the roadbed to achieve the purpose of protecting the roadbed. According to a Chinese patent (CN201721681805.2) a roadbed edge protection device for road construction, the roadbed edge protection device for road construction is equipped with rubber protection The two protective pieces of the sleeve surround the edge of the roadbed to achieve the purpose of protecting the edge of the roadbed, avoiding the occurrence of damage to the edge of the roadbed during the construction process due to human factors, etc., so that the construction can proceed smoothly, and the top of the support column is a hemisphere Shape structure, and the outer surface of the hemisphere is smooth, which ensures the safety of the construction personnel, so that the construction personnel will not be injured by hitting the support column during construction, but the overall anti-collision effect of the anti-collision mechanism of the device is not good, and the anti-collision The collision mechanism cannot be quickly disassembled and assembled. If the anti-collision mechanism is damaged, the protective device cannot continue to be used, which is not practical.
