Road sound insulation wall with anti-collision function

Abstract

The invention relates to a road sound insulation wall with an anti-collision function and belongs to the field of road traffic. The road sound insulation wall comprises I-shaped upright columns, soundinsulation plates, anti-collision rods, connecting pieces, deformed steel bars and nuts, wherein the I-shaped upright columns are uniformly provided with 3-5 upright column bolt holes in the centralline of each lateral flange along the height direction; the sound insulation plates are divided into three layers, wherein bearing plates are arranged at the inner layer, sound insulation cotton is arranged at the middle layer, and outer-layer steel plates are arranged at the outer layer; support ribs are hollow steel pipes and are connected between the bearing plates and the outer-layer steel plates; a top plate and a bottom plate are positioned on the upper and lower surfaces of the sound insulation plates; the edges of the outer sides of the top plate and the bottom plate are flush with theouter-layer steel plates; the anti-collision rods are cylindrical, outer layers of the anti-collision rods are rubber layers, the inner layers of the anti-collision rods are solid shafts, and the radius of an external ring is 3-4 times that of an internal ring; and the external rings of the anti-collision rods are tangent with the bearing plates. The road sound insulation wall provided by the invention has the advantages of being high in strength, capable of realizing the anti-collision function, obvious in sound insulation effect, reliable in connection, high in node strength, convenient totransport, long in service life, short in construction cycle, simple in installation and convenient to maintain and repair, and assembly parts can be prefabricated directly from the factory.

Description

technical field [0001] The invention belongs to the field of road traffic, in particular to a road sound insulation wall with anti-collision function. Background technique [0002] In the process of rapid economic development, along with the large-scale construction of roads, it also brings serious noise pollution. The noise generated does not affect the normal life of the residents on both sides. Usually, sound-absorbing panels are installed on both sides of the road. It is said that the strength of the sound insulation wall is not enough, and it is easy to be dangerous when hit by a vehicle. Contents of the invention [0003] In order to solve the above existing technical problems, the present invention provides a road sound insulation wall with anti-collision function, mainly for the purpose of developing a high-strength, anti-collision function, obvious sound insulation effect, reliable connection, high node strength, convenient transportation, and easy to use Long s...
