Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project construction guardrail. Background Art

[0002] Water conservancy engineering mainly studies the basic knowledge and skills in engineering hydrology, water conservancy engineering surveying, water conservancy reinforced concrete, hydraulic structures, engineering drawing, etc., and conducts engineering planning and design, on-site construction, engineering budgeting, and maintenance and repair of water conservancy equipment in the field of water conservancy engineering. For example: building different types of hydraulic structures such as dams, dikes, spillways, sluices, channels, ferry canals, rafts, fishways, etc. During the construction of water conservancy projects, there will be some dangerous areas that are prohibited for people to enter. At this time, guardrails will be used to isolate these areas to avoid harm to people.
