7. Stack more than 20 tons of Shi Ying Mountain or more than 80 tons of Shi Jing (yellow wax stone, Taihu stone, granite) or more than 6 meters of plastic rockery.

8. Greening projects with a single green belt width of more than 5 meters and a road planting area of more than 10000 square meters.

9. Greening projects with a cumulative width of 4 meters and a road planting area of more than 8,000 square meters.

Three, three kinds of projects:

1, garden construction projects with a single building area of less than 300 square meters.

2. Antique tower with a height lower than 15m.

3, the height of 9 meters below the single eaves archway, archway.

4, 1 10,000 square meters and above comprehensive garden construction.

5. Build a fake stone mountain with a stone mountain below 20 tons or Shi Jing (yellow wax stone, Taihu stone and granite) below 80 tons or a plastic stone mountain below 6 meters high.

6. Sketch of courtyard bridge and garden.

7. Garden Road Project.

8, one-way green belt width of 5 meters, road greening area 1 10,000 square meters below the greening project.

9. A greening project with a cumulative width of 4m and a road planting area of less than 8000m2.

10, cumulative width15m, and three or more green belts (including shoulder green belts) with road planting area less than 40,000m2.

Four, four types of projects:

1 and 1 10,000 square meters.

2. Gardens generally have walls and fences.

3, masonry flower trough, flower pond.

4, only the shoulder greening project.

5. This section is only a greening project of trees on the sidewalk.

6. Other greening projects with accumulated greening area 1 10,000 square meters.

Specific process

1, positioning pay-off:

After entering the site, check the construction location map on the map first. Secondly, the site coordinate points and leveling points are handed over for acceptance. If the error is too large, it should be discussed with * * *, and the formal positioning can only be carried out after confirmation.

Establish control coordinate network and leveling points on site. The leveling points are introduced with permanent leveling points, and measures are taken to protect the leveling points, so as to ensure that the leveling points are cleaned and maintained at the paving site of the compacted macadam (concrete) cushion of the pay-off excavation and filling foundation.

2. Establish plane control network and elevation control network.

The building grid should be designed on the general plan after the site leveling is completed, and its design principles are as follows:

The main axis of the grid should be selected as far as possible on the center line of the site. The endpoints of the vertical and horizontal axes should extend as far as possible to the edge of the site, which is not only conducive to the expansion of the grid, but also ensures the unified accuracy.

The grid side length should not be too long, generally less than 100 m, and it should be a multiple of 100m for the convenience of calculation and memory.

Axis control piles should be measured at the edge of the grid as far as possible.

After the grid survey is completed, the method of locating all buildings at one time is used to test its accuracy, which is a better test method for the grid without adjustment. The measurement method of building grid is to measure the main axis first, then encrypt the grid, and adjust it according to traverse measurement.

The elevation control network is the basic basis for the elevation measurement and transmission of buildings (structures) on the ground and underground in the construction site. The density of the elevation control network should be appropriate. Leveling method can be used in this project.

When the site is longer and wider than 100m, more than four elevation starting points can be arranged in the site to form a closed leveling route, and there are known elevation points for measurement.
