Problems solved by technology

[0002] The site of the construction project is complex and diverse. The calculation of the earthwork on the site is based on the list rule and the quota rule, and the calculation is mainly based on the formula. The difficulty lies in the calculation of the "respective sidelines to the outer sidelines of the outer wall" when calculating the area of ​​the upper, middle and lower bottom of the excavation Part of the center line, the center line is more troublesome to calculate, the area of ​​the middle section is not easy to calculate, and the overlap is not easy to deal with. If some side grading coefficients are inconsistent, it is difficult to deal with
The accuracy of the calculation cannot be guaranteed, and the time at this stage cannot be accurately controlled

Embodiment

[0026] Embodiment: a kind of calculation method of earthwork quantity based on BIM, as attached Figure 1-7 shown, specifically as figure 1 described, including the following steps:

[0027] S1: Select multiple survey points in the survey site.

[0028] S2: Carry out coordinate processing on the survey points in the survey site, such as figure 2 as shown, figure 2 It is the survey point coordinate chart.

[0029] The coordinate processing in step S2 is based on one survey point, and then the relevant coordinate data of the remaining survey points are calculated according to the surveyed site data.

[0030] S3: Import the survey point coordinate data of the site after coordinate processing into the CASS software, and complete the entry of survey point coordinate data, specifically as follows image 3 shown.

[0031] S4: Use the ground red line to connect the peripheral survey points, so as to draw a geological survey map of the surveyed site.

[0032] In step S4, the d...

Abstract

The invention discloses a BIM-based earthwork amount calculation method. The method comprises the following steps: selecting a plurality of survey points in a survey site; inputting the survey point coordinate data of the site subjected to coordinate processing into CASS software to complete input of the survey point coordinate data; Connecting lines to the peripheral survey points by using the red lines so as to draw a geological survey map of the survey site; In the CASS software, dividing the geological survey map into m * m grids, and inputting the elevation of each grid after the actual site is flat on the geological survey map; And using CASS software to calculate the earthwork amount required to excavate or fill the site in the red line in the geological survey map until the site isflat. According to the method, the work amount of earthwork excavation and filling of the project can be accurately calculated, calculation and checking of the cost of the earthwork project are facilitated, and control over the construction progress is enhanced.

Description

technical field [0001] The invention relates to the construction field, in particular to a BIM-based earthwork quantity calculation method. Background technique [0002] The site of the construction project is complex and diverse. The calculation of the earthwork on the site is based on the list rule and the quota rule, and the calculation is mainly based on the formula. The difficulty lies in the calculation of the "respective sidelines to the outer sidelines of the outer wall" when calculating the area of ​​the upper, middle and lower bottom of the excavation Part of the center line, the center line is more troublesome to calculate, the area of ​​the middle section is not easy to calculate, and the overlap is not easy to deal with. If some side grading coefficients are inconsistent, it is difficult to deal with. The accuracy of the calculation cannot be guaranteed, and the time of this stage cannot be precisely controlled. Contents of the invention [0003] The object o...
