Description

Technical Field

[0001] The present invention relates to the technical field of culvert production, and more specifically to a method for improving the perpendicularity of culvert formwork by the density of plumb bobs. Background Art

[0002] A culvert refers to a culvert whose body is built with reinforced concrete box pipe sections. A culvert consists of one or more square or rectangular cross-sections and is generally made of reinforced concrete. However, reinforced concrete is widely used. When the span is less than 4m, a culvert is adopted. For a pipe culvert, a reinforced concrete culvert is a cheaper alternative, and the piers and abutments, and the upper and lower plates are all poured integrally.

[0003] During the actual pouring process, the perpendicularity of the culvert formwork is extremely high. The perpendicularity of the formwork will directly affect the product quality of the later culvert finished product. Therefore, for the existing construction of culvert formwork, the consideration of perpendicularity is crucial. The traditional method of measuring perpendicularity completely relies on the technical level of the construction team and their confidence in technology to determine the accuracy of perpendicularity, and there are often omissions and errors. Therefore, the present invention provides a method for improving the accuracy of perpendicularity. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for improving the perpendicularity of culvert formwork by the density of plumb bobs to solve the problems existing in the above-mentioned background art.

[0005] The present invention provides the following technical solution: A method for improving the perpendicularity of culvert formwork by the density of plumb bobs, including a density increase factor determination module and a density increase correction module. The density increase factor determination module includes the following:

[0006] S101. First, when measuring the perpendicularity, the position of the formwork is determined, recorded according to different positions, and then statistically analyzed;

[0007] S102. Determine the firmness of the formwork. After determining the firmness of the formwork and performing statistical analysis, a plumb line is placed;

[0008] S103. When using a plumb bob to measure the perpendicularity, a tape measure is used at this time;

[0009] S104. Perform distance correction according to whether the measured distance is greater than 500mm. After the distance correction or when the distance is less than 500mm, a formal measurement is performed, and the measured value is recorded at this time;

[0010] Furthermore, the density increase correction module includes the following:

[0011] S201. After obtaining the initial value to be corrected through the density increase factor determination module, compare it with the result of the plan, and determine the range of the increase in the plumb line density during the comparison.

[0012] S202. Determine the error by comparing the ratio between the error value obtained through comparison and the planned value.

[0013] S203. Determine whether to increase the measurement density of the plumb bob according to the level of the error. At this time, continue with the density measurement, and compare the obtained measurement data with the verticality of the plan.

[0014] Furthermore, the determination of the template position in S101 includes the inlet and outlet methods of the template being the upper-in and lower-out method and the conventional inlet and outlet method respectively.

[0015] Furthermore, the increased plumb bob measurement density in S203 is interval measurement, and through interval measurement, it can also be known whether there are phenomena such as template bending.

[0016] Furthermore, the amount of the plumb line density determined by the level of the error of the plumb bob in S203 is as follows:

[0017]

[0018] Through such a setting, it can be clearly seen that the size of the error value determines the number of the increased plumb lines.

[0019] The technical effects and advantages of the present invention:

[0020] 1. Through the density increase factor determination module of the present invention, when measuring the verticality, the template position can be determined. According to different positions, records are made and statistics are carried out, and then the firmness of the template is determined. After determining the firmness of the template and carrying out statistics, the plumb line is placed. When using the plumb bob to measure the verticality, at this time, a tape measure is used for measurement. According to whether the measured distance is greater than 500 mm, distance correction is carried out. After the distance correction or when the distance is less than 500 mm, formal measurement is carried out, and the measured value is recorded at this time.

[0021] 2. Through the density increase correction module of the present invention, after obtaining the initial value to be corrected through the density increase factor determination module, compare it with the result of the plan, and determine the range of the increase in the plumb line density during the comparison. Determine the error by comparing the ratio between the error value obtained through comparison and the planned value. Determine whether to increase the measurement density of the plumb bob according to the level of the error. At this time, continue with the density measurement, and compare the obtained measurement data with the verticality of the plan. Through this method, workers can know the number of measurements to be made and whether the measurement method is accurate, so as to ensure the verticality of the template.
