Description

Technical Field

[0001] The invention relates to the technical field of electric power construction, and in particular to an auxiliary measurement system for calculating angle piles used in electric power construction. Background Art

[0002] As a medium for carrying and transmitting electric power resources, the power grid is the core infrastructure to ensure economic development and people's livelihood. With the rapid development of the economy and society, the construction of smart grids is being actively promoted, which puts higher requirements on power engineering. In the implementation of power engineering, layout is the basic work of power line tower construction (layout is to place the location of the structure designed in the drawing on the construction site). The traditional construction layout operation in power engineering has the characteristics of high precision and large workload.

[0003] In the layout work of overhead line construction of power engineering, the layout of the layout points is based on the tower base. The traditional layout method is to determine the layout direction of the tower leg piles by combining the pit divider with the front and rear sight piles, and then use the tape measure, theodolite, total station and other surveying instruments combined with the design data to locate and layout the coordinates of the layout points. When the coordinates of the center pile are known, each tower needs to be laid out with 4 tower leg piles and 16 tower leg corner piles. The traditional method of laying out the layout points requires manual use of surveying instruments to repeatedly find points, which takes a lot of time and manpower and material resources.

[0004] The invention with publication number CN118208053A discloses a power tower layout system and method based on drone laser guidance. After obtaining the coordinates of the center pile, the coordinates of the tower leg pile and the tower leg corner pile are automatically calculated, and the drone is controlled to fly to the specified position, and the coordinate difference is calibrated in real time. Then, the layout of the layout points is guided by the drone laser and verified.

[0005] As shown in the above invention, the existing layout system realizes accurate calculation, real-time accurate tracking and display of coordinates during the entire layout process. However, this method does not conduct geological surveys on the construction site, and is unclear about the specific conditions of the soil layer below the ground at the construction site. It is impossible to select the position of the corner piles according to the changes in the soil layer, thereby causing deviations in the project volume and budget. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See Figure 1-2 The present invention provides an auxiliary measurement system for calculating angle piles for electric power construction, comprising:

[0042] The geotechnical survey module is used to conduct geological surveys at the construction site and collect corresponding survey data. The survey data include the distribution characteristics of each soil layer at the construction site, water level, natural gravity, and floating gravity. According to the survey data, survey drilling maps and geological cross- and vertical profiles are drawn. The geological cross- and vertical profiles clearly define the soil boundaries of each stratum. According to the geophysical data such as high-density seismic imaging detection, transient surface wave detection, geological radar detection and the drilling data of encrypted survey holes in the cave area, the geological data and geological cross- and vertical profiles are corrected to refine and improve the spatial information, boundary lines, directions and development trends of the caves.

[0043] The model generation module is used to establish a three-dimensional geological model of the construction site based on the survey data. Revit software is used to establish the three-dimensional geological model of each geological layer interface including the bearing layer interface and the natural ground after leveling, forming a geological contour interface of the construction area. When establishing the three-dimensional geological model, a comprehensive exploration method of geophysical exploration (wave velocity, resistivity, geothermal testing, electrical depth sounding) and comprehensive geological analysis is used to verify the exploration data. The three-dimensional geological model is established based on the revit platform. A new volume family is created on the revit platform, and geological horizontal and vertical profiles are imported. The revit platform automatically picks up the geological profile boundary vector line, and the volume stretching function is applied to generate a three-dimensional geological model.

[0044] The three-dimensional geological model of the present invention combines the exploration data formed by various geological exploration methods. Various geological exploration methods use the data formed by drilling exploration as a reference and verify each other, so as to accurately supplement the geological data between the boreholes in the drilling exploration method, so that the address data can be obtained accurately and reliably, and the parameters of the actual complex geological conditions can be obtained. The geological cross-section map and the geological longitudinal section map are drawn using the accurate exploration data, and then a plurality of geological cross-section maps and a plurality of geological longitudinal sections are combined to form a three-dimensional geological model. Before forming the three-dimensional geological model, the geological cross-section and the geological longitudinal section can be corrected and refined, thereby improving the drawing accuracy of the geological cross-section and the geological longitudinal section.

According to the engineering design data and the three-dimensional geological model, in accordance with the power engineering standards, the layout point coordinates are calculated to generate the layout point coordinates of the corner piles.

[0047] The parameter calculation module is used to use the three-dimensional geological model to obtain the rock surface elevation of the corresponding construction site, calculate the pile bottom elevation of the corresponding corner pile in combination with the obtained rock penetration length, calculate the pile length of the corner pile using the pile top elevation and pile bottom elevation at the coordinates of the corner pile setting out point, and build a three-dimensional model of the bored cast-in-place end corner pile and the cap in the three-dimensional geological model based on the Revit software, and calculate the shear bearing capacity of the rectangular cap under the corner pile and the non-rectangular cap under the corner pile.

[0048] The calculation formula for the punching bearing capacity of rectangular cap corner piles is:

[0055]

[0058] It is further explained that in order to ensure the reliability of program operation and avoid errors in the identification of intersection points, a manual inspection link is also set up in this embodiment, namely: programming is performed using the Dynamo visual programming tool. By running the program, an auxiliary component is added at each identified intersection point of the corner pile and the bearing layer interface to mark the position of the intersection point, which is convenient for inspectors to observe with the naked eye. During the inspection, the position of the auxiliary component on each corner pile in the construction model is observed from the three-dimensional view to determine whether the auxiliary component is located on the cutting cross section where the upper interface of the bearing layer in the construction model intersects the corner pile.
