Engineering method for measuring and constructing polyvinyl chloride (PVC) cylinder leveling device

Abstract

The invention relates to the field of building construction, in particular to an engineering method for measuring and constructing a polyvinyl chloride (PVC) cylinder leveling device for benchmark measurement when a linear distance is less than 50m at a main body or decoration construction stage of constructional engineering. The engineering method comprises the following steps of: fabricating a PVC cylinder device; detecting the tightness of the PVC cylinder device; fixing the PVC cylinder; filling the PVC cylinder device with water, and exhausting air bubbles; re-checking and measuring a reference point; adjusting water quantity, and measuring a height difference between the reference point and a liquid level of a hose; and measuring elevation and scribing marks. The invention is made of daily materials according to the principle of a communicating vessel; the engineering method is simple and easy to understand, low in manufacture cost, and convenient to operate; by the invention, the construction efficiency is improved, better social and economic benefits are achieved, and the invention has higher promotion value and development prospect.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a measurement construction method of a PVC cylinder leveling device applied to the main body of a building project or when the straight-line distance of a decoration construction stage is less than 50m. Background technique [0002] The normal way to measure the horizontal elevation in civil construction is to use a level. During the main construction, after the horizontal support system of the operation layer is erected and the beam and slab formwork is installed, the level point of the next layer is vertically measured to the local level according to the layer height. Mark and mark on the steel bars of the first floor column, set up a level on the formwork, and use the measured level point as the backsight point to measure the remaining level points within the plane range. Because the stacking of materials affects the line of sight, it will cause inconvenience to the operati...

[0002] The normal way to measure the horizontal elevation in civil construction is to use a level. During the main construction, after the horizontal support system of the operation layer is erected and the beam and slab formwork is installed, the next level is measured vertically according to the height of the floor. Mark and mark on the steel bars of the first floor column, set up a level on the formwork, use the measured level point as the backsight point, and measure the other level points within the plane range. Because the stacking of materials affects the line of sight, it will cause inconvenience to the operation; during decoration construction , due to the blocking of the room partition wall, multiple testing is required, and the work efficiency is low
