Description

Technical Field

[0001] The invention relates to a multifunctional iron tower foundation measuring tool, specifically a tool for measuring the foundation of a iron tower in a plain, mountainous or hilly area, with four foundation pits at different levels, without complicated calculations. Ordinary construction workers can quickly measure the root opening of the iron tower foundation, the elevation of the bottom of the foundation pit and the top of the foundation, whether the center of the foundation pit is consistent with the line direction and other data, and carry out data monitoring during construction. Background Art

[0002] At present, the division of pits and construction measurements of line tower foundations are generally carried out by technicians using theodolites, levels, total stations and GPS measurements to locate and calculate, and use tape measures to measure specific division pit positioning points and calculate the depth of the pits on site. However, when measuring straight lines during the construction of tower foundations in mountainous areas, the overall rocks affect the measurement, and it is troublesome to clean them up, making it difficult to measure straight line data on the ground; if distance measuring instruments, total stations and GPS are used, due to the large drop of tower foundations in mountainous areas, the verticality of the measuring rod is difficult to control, and the values ​​measured with a slight tilt will have large errors. At the same time, complex calculations are required for angle measurement and conversion, and the equipment and instruments are expensive and the operating procedures are cumbersome.

[0003] The method of arranging positioning piles at the bottom of the foundation pit is generally to first arrange auxiliary positioning piles around the foundation pit, and then arrange positioning piles at the bottom of the foundation pit based on the auxiliary positioning piles during the foundation pit excavation process. The procedure is complicated, and it is easy for workers to make mistakes in data measurement during construction, and the actual data does not match the drawing data, resulting in rework. At the same time, when relevant personnel conduct supervision and acceptance, complex calculations must be performed when the foundation pit is on different levels, making the supervision and acceptance process complicated and slow.
