[0004] (1) When the surveyor uses a measuring device equipped with a level to measure the height difference between the construction ground points, he usually needs to hold a record book to record the measured value in order to calculate the height difference between the construction ground points. Therefore, during the measurement process, always need a Holding a notepad in one hand, the hands of the construction workers cannot be freed, and it is inconvenient to record the measurement data, which makes the measurement process cumbersome. The measuring instrument for civil engineering measurement is generally supported by a triangular bracket, which is bulky and inconvenient to carry, and it is difficult to install and disassemble. The speed is slow, which affects the accuracy of measurement data and measurement efficiency
[0005] (2) Only one of the measurement tools of the level, theodolite or spirit level can be used for the installation observation measurement of the tripod on the triangular corner, and in the measurement of civil engineering, it may be necessary to concentrate three or more measurement tools at the same time. For the measurement on the reference point, every time a measurement tool is replaced, a new horizontal calibration and positioning of the reference point are required, which greatly affects the measurement efficiency in civil engineering;
[0006] (3) The bottoms of the existing levels and theodolites are all provided with foot screws. Because the foot screws can only be fine-tuned in a short distance, the adjustment range is limited, so that the flatness of the ground has certain requirements, and when installing the tripod , it is necessary to manually adjust the horizontal visual adjustment of the tripod, and finally to fine-tune the foot screw, which requires two steps of adjustment. When the foot screw adjustment exceeds the range, how can it be necessary to re-adjust the height of the support point of the tripod, and further increase the measurement time. The level of preparation time for the measurement environment

Abstract
The invention discloses a civil engineering measuring device. The civil engineering measuring device comprises a base and a storage groove formed in the upper surface of the base. The storage groove is internally provided with a combined measuring frame, main telescopic devices are arranged at both ends of the combined measuring frame through a single adjusting device. The other ends of the two main telescopic devices are hinged to the corners on two adjacent sides of the storage groove, auxiliary telescopic devices are arranged on the inner sides of the main telescopic devices, one ends of the two auxiliary telescoping devices are connected to the combined measurement frame, the other ends of the two auxiliary telescopic devices are connected to the middle of the side wall of the storagegroove, and one of the main telescopic devices is provided with a hammer pendulum measuring device. Rich measuring devices are provided, recalibration in the civil engineering measuring process is avoided, the horizontal calibration of an automatic measuring base point is realized, the error in the measuring process is reduced, the accuracy of measuring data is improved, and the structure is simple and portable.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a civil engineering measuring device.
