Safety protection semi-circular groove device for low-grade highway roadside electric pole piece

Abstract

The invention belongs to the technical field of road traffic safety, and particularly provides asafety protection semicircular groove devicefor a low-grade highway roadside electric power rod piece. The device comprises an anti-collision pad used for automobile collision prevention, the anti-collision pad is a hollow annular sealing sleeve piece, and the inner wall of the annular sealing sleeve piece is fixedly attached to and surrounds an electric power rod piece. The length of the anti-collision pad is not smaller than 90 cm, and the inner side of the anti-collision pad is of a concave-convex circular groove structure with protrusions and grooves arranged alternately. According to the scheme, the contact area of the telegraph pole and an automobile is expanded, and after the device is collided, the device deforms and absorbs energy, so that the reaction is reduced, the deformation and acceleration of the automobile can be effectively reduced, harm to the automobile and passengers caused by collision of the automobile and the telegraph pole is reduced, the road safety is improved, and the passengers are protected; and on the other hand, the anti-collision pad is directly arranged on the power pole in a sleeving mode before the power pole is put into use by adopting an assembling mode, the construction process is simple, and the requirements for manpower and material resources are small.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety, and in particular relates to a semi-circular groove device for safety protection of electric rods on the side of a low-grade highway. Background technique [0002] Early utility poles were all made of wood, which has the advantages of easy material acquisition, light weight, and easy erection. With the development of steel and reinforced concrete, and technical requirements, these two materials have gradually replaced wood utility poles. Among them, reinforced cement concrete (also known as cement rod) is divided into two types: prestressed and non-prestressed, and the specifications of prestressed cement rod are mainly: The specifications of non-prestressed cement rods are mainly: rice, Wait. The utility poles made of steel materials are made of high-strength steel such as Q235 carbon structural steel Q345, Q390 low-alloy steel Q420, etc. The thickness is generally between 5...
