Description

Technical Field

[0001] The invention belongs to electric power facilities, and in particular to a method for calculating the amount of concrete used for a conical pole in a pole preparation process. Background Art

[0002] The existing concrete volume of electric poles is calculated based on the size of the poles and the thickness of the concrete. The calculation formula is concrete usage = pole length × pole diameter × π÷4 × concrete thickness. Generally, π is taken as 3.14 and the concrete thickness is 25cm. This calculation method is highly applicable to poles of equal diameter and the calculation results are relatively accurate. However, this method is not accurate for tapered poles and there is some difference from the actual usage.

[0003] During the construction of power line poles, the amount of concrete used directly affects the construction cost of the poles. Therefore, it is necessary to fully consider the cost factor during the design and construction stages, reasonably arrange the amount of concrete, and try to reduce the amount of concrete to reduce the construction cost while ensuring the safety and stability of the poles. At the same time, in the process of preparing the poles, it is also crucial to accurately calculate the amount of concrete, estimate the actual production amount, and compare it with the actual amount. It is also crucial to control the amount of concrete in the production process, which can effectively control the amount of concrete in the manufacturing process and improve production efficiency. In addition, the accurate calculation of the amount of concrete used for the poles is of great significance to ensure the safety and stability of the poles and control the construction costs. Summary of the invention

[0004] The problem to be solved by the present invention is to accurately calculate the amount of concrete used for the tapered pole, so as to control the production process, improve production efficiency, and ensure that the pole meets quality requirements.

[0005] A method for calculating the volume and mass of tapered pole concrete, characterized in that the method is implemented by the following steps:

[0006] Step 1: According to the tapered pole design plan, obtain the outer radius R of the concrete pole tip 1 、Wall thickness H 1 , starting position S of the pole section to be tested 1 , end position S 2 ;

[0007] The starting point position S of the pole segment to be tested 1 Refers to the distance from the smaller end of the segment to the pole tip that needs to be measured in the entire pole;

[0008] The end position S 2 Refers to the distance from the larger end of the segment to the pole tip that needs to be measured in the entire pole;

[0009] Step 2: Calculate the inner radius r of the tip according to the data obtained in step 1.1 , the square difference between the inner and outer radii of the tip F, the volume of the segment from the tip to the starting point V 1 , the volume of the segment from the tip to the end point V 2 ; The calculation method is as follows:

[0010] r 1 =R 1 -H 1 ;

[0011]

[0012] Step 3: Based on the results of step 2, calculate the concrete volume V and mass M of the segmented part of the pole to be tested. The specific calculation method is as follows:

[0013] V=V 2 -V 1 ;

[0014] M = V × ρ;

[0015] Among them, ρ is the density of the concrete of the pole to be tested, which is obtained through testing;

[0016] Step 4, adjusting the concrete mass M obtained in step 3 to obtain the final concrete mass m, specifically:

[0017] m = α × M;

[0018] Among them, α is the adjustment coefficient.

[0019] The coefficients are adjusted accordingly based on the concrete mould error and concrete loss.

[0020] The outer radius R of the concrete pole tip 1 、Wall thickness H 1 The dimensions of poles designed according to national standards.

[0021] The calculation method of the present invention does not adopt the traditional calculation method of equal-diameter poles, but takes production practice into consideration. The error between the calculation result and the actual usage is very small, which has a certain guiding and controlling effect on the production process, improves work efficiency, and ensures the quality of the poles.
