Engineering surveying device and use method thereof

Abstract

The invention discloses an engineering surveying device and a use method thereof, the engineering surveying device comprises a support, the support is provided with a lifting mechanism, the lifting mechanism is provided with a horizontal adjusting mechanism, and the horizontal adjusting mechanism is rotatably connected with a pay-off measuring mechanism; the paying-off measuring mechanism comprises a rotating disc, a U-shaped groove is fixedly connected to the rotating disc, a paying-off part is rotationally connected into the U-shaped groove, the paying-off part comprises a rotating block, a main shaft penetrates through the rotating block and is fixedly connected with the rotating block, the two ends of the main shaft are in shaft connection with the two sides of the U-shaped groove, a groove is formed in the rotating block, three lasers and an angle adjusting part for adjusting the angles of the lasers are arranged in the groove, a first spring is fixedly connected between the bottom face of the rotating block and the bottom face of the U-shaped groove, and a locking part is arranged on one side of the rotating block. The device can complete one-time paying-off, and is simple in operation and high in measurement precision.

Description

technical field [0001] The invention relates to the technical field of engineering surveying, in particular to an engineering surveying device and a use method thereof. Background technique [0002] Construction setting out is to ensure that the construction project is carried out safely and smoothly in accordance with the requirements of planning approval through prior inspection of the construction project positioning and setting out. At the same time, it takes into account the improvement of municipal facilities and environmental quality to avoid infringement on the interests of adjacent property rights subjects. Measuring and setting out is one of the very important processes in pipeline laying, civil engineering and other engineering constructions. The accuracy of measuring and setting out directly affects the accuracy of pipeline construction routing. In the past, the practice of engineering survey and setting out was to use measuring equipment to locate the pile point...

AI Technical Summary

Problems solved by technology

The existing measuring and setting-out devices use lasers to make dots on the ground and then sprinkle lime powder. However, the existing measuring and setting-out devices can only set one pile at one point, and multiple measuring and setting-out devices are required when lime powder is spread. It is arranged horizontally and requires multiple surveyors to work together to complete the marking. The operation process is cumbersome and the measurement accuracy is greatly affected.
