Safety guards for asphalt pavement construction

Abstract

The invention relates to the field of pavement construction protection, and discloses a safety protection device for asphalt pavement construction. There are two supporting rods in total, and a protective frame is arranged between the two supporting rods. The inner side of the protective frame is fixedly connected with a protective net. The upper end of the protective frame is provided with a cavity, and the upper end of the protective frame is provided with a cavity. An anti-climbing device is arranged in the cavity, and a connecting device is arranged between two ends of the protective frame and the support rod. The invention can effectively solve the problem that the existing protective device is mostly a whole, which is inconvenient to disassemble and install, resulting in the problem of increased transportation cost, and at the same time solves the problem that the anti-theft cone thorn at the upper end of the existing safety protective device cannot be hidden and easy to thorn. injury to staff.

Description

technical field [0001] The invention relates to the field of pavement construction protection, in particular to a safety protection device for asphalt pavement construction. Background technique [0002] Asphalt pavement refers to various types of pavements paved with road asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage caused by traffic and natural factors, making the road smooth, less dust, impermeable and durable. Therefore, asphalt pavement is one of the most widely used advanced pavements in road construction. Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture formed by fully mixing asphalt material with a certain viscosity and an appropriate amount and a certain gradation of mineral aggregates. As the asphalt pavement material, asphalt concrete has to withstand the repeated action of the vehicle load and the long-term...
