Hydropower construction how to put out line?

Hydropower construction how to put out line?

1, according to the comprehensive point map construction lay out, determine the lighting, spray, smoke sense point, on this basis can avoid the collision with the main keel and vice keel point, at the same time, the finished surface of the smallpox shape lay out can effectively ensure the accuracy and uniformity of size.

2. The drawings of key parts of toilet water and electricity are deepened. The urinal bucket and squat toilet shall be confirmed according to the line laid out on the ground after the stone layout is completed, and whether the sanitary ware is centered after the installation is completed.

3. When deepening the drawing, whether the installation size of water and electricity sanitary ware can meet the specific requirements of site construction should be considered, and whether to change should be further explained.

4. When laying out cables on the wall, the prepared template should be used first, and then the icon should be sprayed onto the wall with spray paint; Check whether each point is correct and there is no deviation according to the drawing.

5. Wiring acceptance requirements

1. Wall positioning

Wall point layout positioning, switch socket layout must be in the wood veneer, wallpaper center point;

Toilet washbasin layout positioning should be considered to install the washbasin center and water supply, drainage embedded in the center of the pipeline.

2, bathroom shower room location

1) Toilet floor positioning, laying out and stone positioning, laying out and stone partition layout;

2) wall shower room mixed faucet positioning should be based on the size of the shower room to locate the center, its height should be based on the design elevation to locate;

3) When locating the bathtub, the drainage of the bathtub, the location of the water supply port and the location of the access port should be considered to ensure that it meets the installation requirements.

4) For the positioning of the toilet drain pipe, the construction personnel shall decorate the base line and complete the site disclosure of the surface line to the hydropower team leader. The hydropower shall be laid out on site according to the size requirements of the equipment installation drawings and decoration drawings. After the point location is determined, the construction personnel shall confirm it and make the positioning opening.

3. Locate the drain pipe

The hole size of the wall bushing for the drainpipe should be added to the thickness of thermal insulation cotton according to the pipe diameter. The gap between the bushing and the pipe should be filled with flame retardant dense material, and the end face should be smooth.

4, fixed point positioning unified requirements

In order to ensure that the top, ground and wall points can be accurately in place when the professional installation, the fine decoration unit should cooperate with the installation unit for laying out and positioning; After the completion of point placement, the accuracy of the placement should be further determined by each professional.

In the process of hydropower construction, we should pay attention to a lot. The above hydropower construction technology disclosure is only a part of it. If there are problems, they should be found, solved and prevented as soon as possible. If you want to do a good job in hydropower engineering, in addition to on-site construction experience, it is more important to have systematic thinking.
