Question 1: Municipal road budget, how to calculate excavation. The calculation method is:

1. According to the road elevation in the design drawing, draw the excavation and fill cross-section in CAD. The middle elevation of the road, the elevation of the top of the roadbed, the cross slope of the road, and the original landform line are marked on the map. Then directly use the AA command of CAD to click on the excavation and filling area, and mark At and Aw in the lower right corner.

2. According to each cross-section and the area stuck in the cross-section. Statistical calculations can be done through EXCEL tables. Please see attached picture 2.

3. If you just want to make a simple budget, you can just calculate it in an EXCEL table.

Municipal roads are divided into four categories: expressways, trunk roads, secondary trunk roads and branch roads. Expressways are set up in megacities or large cities. They use central separation belts to separate upstream and downstream vehicles and are dedicated expressways for automobiles. They mainly connect major urban areas, urban areas and major suburbs, satellite towns, It is connected to the main external roads, bears the main passenger and freight traffic in the city, and has high speed and large traffic capacity. Trunk roads are the skeleton of the urban road network, connecting the city's main industrial areas, residential areas, ports, airports, stations and other passenger and freight centers, and are responsible for the city's main transportation tasks. It is not advisable to build too many pedestrian and vehicle entrances on both sides of the main road, otherwise the vehicle speed will be reduced. Secondary trunk roads are ordinary traffic trunk roads in the urban area. They cooperate with the trunk roads to form an urban trunk road network. They serve to connect various departments and collectors, and share the traffic load of the trunk roads. The secondary trunk road also has service functions, allowing public buildings to attract people to be arranged on both sides, and parking lots should be provided. The branch road is the connection line between the secondary trunk road and the neighborhood road. It is set up to solve the traffic problem in local areas and mainly serves service functions. Some major branch roads can be equipped with bus lines or dedicated bicycle lanes, and there should be no transit traffic on the branch roads.

Question 2: Municipal road budget, how to calculate excavation. The calculation method is:

1. Draw the excavation and fill cross-section in CAD based on the road elevation in the design drawing. The middle elevation of the road, the elevation of the top of the roadbed, the cross slope of the road, and the original landform line are marked on the map.

Secondary trunk roads are ordinary traffic trunk roads in the urban area. They cooperate with the trunk roads to form an urban trunk road network. They serve to connect various departments and distribution arcs and share the traffic load of the trunk roads. The secondary trunk road also has service functions, and public buildings to attract people are allowed to be arranged on both sides, and parking lots should be provided. The branch road is the connection line between the secondary trunk road and the neighborhood road. It is set up to solve the traffic problem in local areas and mainly serves service functions. Some major branch roads can be equipped with bus lines or dedicated bicycle lanes, and transit traffic should not be allowed on the branch roads.

Question 3: How to calculate road filling 1. Calculation of site leveling and rolling engineering quantities:

1. Leveling the site refers to the thickness of the excavation and filling of the construction site within ± Within 30cm and leveled. When the thickness of excavation and filling exceeds ±30cm,

shall be calculated separately according to the site's earthwork balance vertical layout plan.

2. The amount of site leveling work is calculated in square meters according to the dimensions shown in the design diagram, plus 2m on each side of the outer edge of the building's exterior wall.

3. The rolling pressure of the original soil at the construction site is calculated in square meters, and the rolling pressure of the filling soil is calculated in cubic meters according to the filling thickness as shown in the figure.

2. Calculation of earthwork (rock) quantities for excavation trenches and foundation pits:

Division of trenches and foundation pits: The bottom width of the trench as shown in the figure is within 3m, and The groove length is more than three times greater than the groove width.

Any foundation pit with a bottom area within 20m2 as shown in the figure is a foundation pit.

If the trench bottom width shown in the figure is more than 3m, the pit bottom area is more than 20m2, and the thickness of the excavation and filling of the flat site is more than 30cm, it will be calculated as excavated earth.

2. When grading is required to calculate trench excavation, foundation pit, and earthwork quantities, the grading coefficient can be calculated based on the quota.

3. When excavation of trenches or foundation pits requires retaining earth slabs, the width shall be calculated based on the bottom width of the trench and foundation pit as shown in the figure, plus 10cm on one side and 20crn on both sides.

The area of ??the retaining slab is calculated based on the vertical support area of ??the trench and pit. After the retaining slab is supported, the grading is no longer calculated.

4. The working area required for foundation construction shall be calculated based on quota.

5. The length of the trench shall be calculated according to the length of the center line as shown in the figure for the exterior wall; the length of the net long line between the bottom surfaces of the foundation as shown in the figure for the interior wall.

If there is a pad on the foundation, When there are layers, it is calculated based on the net long line length between the bottom surfaces of the cushion; the volume of the internal and external protruding parts (stacks, wall-attached chimneys, etc.)

is incorporated into the trench earthwork volume for calculation.

6. When digging a pipeline trench, calculate the length of the center line as shown in the figure. If the trench bottom width is specified in the design, it shall be calculated according to the specified size; if the design

does not specify, the width of the trench bottom shall be calculated according to the following table. Width calculation.

7. The depth of trenches and foundation pits is calculated according to the depth from the bottom of the trench or pit to the outdoor floor as shown in the diagram; the depth of pipeline trenches is calculated according to the depth from the bottom of the trench to the outdoor floor as shown in the diagram.

Question 4: How to calculate the earthwork of road engineering and draw a cross-section diagram. According to the excavation and filling area of ??the cross-section diagram, use the average cross-section method to calculate, (A1+A2)/2*L

Question 5: How to calculate the earthwork in the road construction drawing? Calculate the cross-sectional area of ??the excavation and filling of the earthwork according to the cross-sectional view of the road, take the average of the adjacent cross-sectional areas and then multiply by the distance between the two sections to get each The amount of earthwork excavation and filling of a section is then summed up to obtain the total amount of earthwork excavation and filling.

Question 6: How to quickly calculate the amount of earthwork based on the road design cross-section? 1. First measure the area between the design road surface and the ground line of two sections of a mileage, then take the average value and multiply it by the length.

2. After imagining that the object is cut open with a section plane, only the orthographic projection of the part in contact with the object is drawn. The resulting figure is called a cross-section diagram.

3. The calculation of earthwork volume is an important step in the construction of construction projects. The amount of earth and stone must be budgeted in the design stage before construction, which is directly related to the cost estimate and program selection of the project.

Question 7: Road earthwork calculation Road earthwork calculation is very simple. You need two data: one is the design cross-section data, and the other is the original ground data.

Put the design line on the original ground and fill and cut it out. I will give you a teaching video
