Description

A kind of temporary protective fence for municipal engineering which is convenient for transportation

technical field

The utility model relates to a protective fence, in particular to a temporary protective fence for municipal engineering which is convenient for transportation, and belongs to the technical field of engineering construction protective facilities.

Background technique

Municipal engineering refers to municipal infrastructure construction projects. In my country, municipal infrastructure refers to various projects that are set up within the planning and construction scope of urban areas and towns (townships) and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. Buildings, structures, equipment, etc., all kinds of public infrastructure construction supporting urban life belong to the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage treatment and disposal Other projects, such as various pipelines closely related to life, rainwater, sewage, water supply, reclaimed water, electricity (outside the red line), telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all belong to the municipal government. During the construction period, in order to protect and protect personal safety and equipment and facilities, it is often necessary to temporarily erect protective fences around the construction site.

The existing guardrail structure is relatively simple:

1) The surface of the traditional guardrail is not sprayed with paint. Long-term use will easily cause the guardrail to be corroded and rusted by the environment, thereby shortening its service life, and there is no eye-catching sign on the guardrail, which is not easy for people and vehicles to identify and observe at night. Therefore, the occurrence of various accidents cannot be effectively avoided. At the same time, the column used is welded and fixed on the bottom plate. Although the connection is very firm, it is not convenient for later disassembly and recycling;

2) During the installation process, the bottom end of the guardrail is often pre-buried on the ground. Although the installation is stable, it cannot be moved, and thus the purpose of temporarily erecting the guardrail cannot be achieved. The protection range is adjusted according to the actual construction space, and the guardrail cannot be folded and stored, making it easy to take up a lot of space during transportation.
