Which enthusiastic netizen can provide a greening construction plan for the substation site

Evergreen trees.

Class planting hole specifications, should be based on (tree height and soil balls.

diameter) to determine.

Evergreen arbor planting hole specification (cm):

Tree height, soil ball diameter, planting hole depth, planting hole diameter.

Generally, the size of the planting hole should be determined according to the variety specifications of the planted trees, the root system of the seedlings and the diameter of the soil ball, and the soil conditions. For trees with a DBH of more than 5 cm and evergreen trees with a height of more than 2 m, scaffolds should be set up to fix them.

Wow, you're ruthless enough to want such a difficult solution with 5 points.

If you don't have any material on this, you can go to the civil engineering website and take a look.

1. Earthwork excavation is carried out in turn from east to west, and a certain slope is made at any time, and water shall not accumulate within the scope of the slope. Foundation pit excavation measurement is a key process, the depth of the foundation pit is consistent, once the measurement is wrong to correct it is difficult. Slopes, edges, and elevations should be measured and controlled.

When the elevation is fast to the bottom, it shall not be over-excavated. First hit the 500 line above the base, and then the edge line to the plane depth to hit a small elevation pile, not only to control the machine digging but also to control the manual cleaning. If there is an over-excavated part, it will be treated according to the design requirements.

Error control: 1 base elevation: 0, 30.

2.Slope excavation to control the slope and depth, mechanical excavation should be left with manual cleaning thickness, this project is 200 thick, and then manually trim the slope, each excavation step using line drop, ruler, cross stem to measure the slope. And often supervise the state of the slope, and timely adjust and deal with or strengthen when there is a problem.

Start Determining the Slope.

Determine the order of excavation.

Measure pay-off. Earthwork excavation.

Trimming and clearing. When completing 3 mechanical excavation, with 3-4 manual soil clearing, mechanical excavation can be excavated at one time in a shallow foundation pit within 5m deep. When approaching the design pit bottom elevation or slope boundary, a soil layer of 200 300mm thick should be reserved, excavated and trimmed manually, and the slope should be repaired while digging to ensure that the soil and elevation are not disturbed to meet the design requirements.

4. After excavation to within 50cm from the bottom of the groove, the surveyor measures the horizontal marking line of 50cm from the bottom of the groove, and then nails small wooden stakes on the groove or the bottom of the foundation pit, and uses them to control the elevation when cleaning the bottom soil layer. According to the axis and foundation contour, the size of the foundation groove is checked, and the slope and base are trimmed.

5. During the construction during the rainy season, the protection of the slope should be strengthened. Appropriately slow down the slope or set up support, and at the same time excavate the ditch with an earth embankment on the outside of the pit, and 6 when the soil is spoiled on the upper side of the excavation, ensure the stability of the excavation slope. The distance from the foot of the spoil mound to the upper edge of the cut is determined according to the depth of the cut, the slope slope and the nature of the soil. The top surface of the spoil pile should be inclined outward to prevent the hillside water from flowing into the excavation site.

7 In the process of earthwork excavation, if there are signs of landslides (such as cracks, sliding, etc.), the following measures should be taken immediately:

1) Suspension of construction. Evacuate all personnel and machinery to a safe place;

2) Notify the design unit to propose treatment measures;

3) Set observation points according to the signs of sliding, observe the plane displacement and settlement changes of the landslide body, and make a record.

8. The plain fill soil should be removed and excavated to the design elevation. If you do not reach the soil layer, you should continue to dig down to the soil layer and enter the soil layer. When the foundation is located on fully weathered rock, the cushion should be paved immediately after the excavation of the foundation pit during construction, and the exposure should be shortened as soon as possible.

9. Manual cooperation with mechanical construction, mainly responsible for slope cleaning and supervision of the base edge, manual excavation of the base, and leveling the base plane.

10.The foundation pit prevents ground rainwater and sewage from pouring into the pit, and a retaining wall is set around it. Outside the scattered water, the surface water drainage system is made.

11.After the base elevation is in place or the brazing finds that the base soil has a sandwich and a weak layer that does not meet the design requirements, it should be dealt with according to the design opinions and shall not be dealt with by itself.

12.During the excavation, the management personnel should carefully monitor the changes in the soil layer and the state of the slope.
