Геодезичний контроль гідростатичним нівелюванням якості будівельно-монтажних робіт

Abstract

According to the results of the research analysis, the existing hydrostatic levels used in construction for high-precision assembly of elements of buildings and structures, engineering networks and technological equipment have been characterized. Their design features, advantages and disadvantages, accuracy of measurement of excesses are determined. The design of a hydrostatic leveler is proposed for determining significant amounts of excesses exceeding the height of interconnected vessels. The device contains basic and non-basic vessels filled with working fluid and hydraulically connected to each other by a flexible pipeline. A spring-loaded float is placed in the non-basic vessel, rigidly connected to the rod, which can freely move vertically. Vessels are equipped with heel pads to install them at the points between which the excess is determined. Scales for taking readings are applied to the dishes connected to each other. The formula for determining significant excesses is given, taking into account the correction for the amount of compensation of excess pressure of the working fluid, taking into account the force perceived by the damping devices. A refined formula is proposed for determining the mean square error of determining the excess by hydrostatic leveling, taking into account the error due to the inaccuracy of compensation of the excess pressure of the working fluid, taking into account the pressure damping force.
