Cost calculation of isolation fence for drinking water source protection area of Qinghai reservoir using metal wire mesh

After the installation of the isolation fence in the reservoir drinking water source protection area, unrelated personnel will be prevented from entering the first level protection area, ensuring that there are no tourism, swimming, fishing or other activities that may pollute the water source within the first level protection area, and the safety of residents' drinking water is more guaranteed.

The standardized construction of centralized drinking water sources, including the installation of isolation and protection facilities, the establishment of boundary markers, warning signs, and other projects, is a livelihood project related to water safety, overall development, and the well-being of thousands of households.

Protect drinking water sources. Planning, constructing protective nets, and setting up signage are important measures to protect drinking water sources. Firstly, isolation barriers can prevent unrelated personnel from entering the first level protected area, achieving one

There are no activities such as livestock and poultry breeding, cage farming, tourism, swimming, fishing, or other activities that may pollute water sources within the level protection zone. Secondly, the establishment of signage is to publicize the protection standards for drinking water sources to the society

Surrounding, content requirements, and enhancing work transparency have made it convenient for the public to report water environment violations in a timely manner. At the same time, with the eye-catching and appealing nature of boundary markers and warning signs, the society has been mobilized

The public will actively participate in the protection of drinking water sources. Thirdly, the presence of guardrails and signage can warn residents around the water source protection area to enhance their awareness of environmental protection and self-discipline, and not to act recklessly in the water

Any behavior that may pollute water sources within the protected area will be investigated and punished.

So next, let me introduce to you what specifications are generally used for physical isolation barriers in reservoir water source protection areas?

1、 Specification and model of physical isolation barrier for reservoir water source protection area

1. Mesh size (mm): 75x150

2. Mesh (mm): 1800x3000

3. Frame (mm): 20x30x1.5

4. Mesh impregnation (mm): 0.7-0.8 Mesh after plasticization (mm) 4.8

5. Column size (mm): φ 48x2x2200, mainly using ordinary 48 cylinder top integral bending: 30 ° bending length (mm): 300

6. Column spacing (mm): 3000

7. Pre embedded column (mm): 250-300 Pre embedded foundation (mm): 500x300x300 or 400 x400 x400

2、 Advantages of physical isolation barriers in reservoir water source protection areas

1. The grid structure is concise, beautiful and practical;

2. Easy to transport and installation not limited by terrain undulations;

3. Especially adaptable to mountainous, sloping, and multi curved areas;

4. The price is moderate to low, suitable for large-scale adoption.

The above is an introduction to the technology of physical isolation barriers for reservoir water source protection areas. Now, let me introduce the issue of cost accounting. We have cash payment for physical isolation barriers, with prices ranging from 15-25 yuan/meter for bilateral isolation barriers and 25-30 yuan/meter for frame isolation barriers.If it is customized according to the drawings, the price will be higher than the current payment. The price of the customized version is related to the specifications of the materials on the drawings and the quantity ordered. If you have any questions about the cost of physical isolation guardrails, please feel free to consult me at any time.
