Arc pipe construction method for mechanical arcing

Abstract

The invention discloses an arc pipe construction method for mechanical arcing, and belongs to the technical field of building construction. An arcing machine is adopted to press arcs on arc pipes to be constructed, and comprises two fixed wheels symmetrically arranged in the horizontal direction and a movable wheel moving in the vertical direction; the circle center of the movable wheel is positioned in the center line of the circle center connecting line of the two fixed wheels; firstly, radians and radiuses of the arc pipes to be constructed are calculated according to the shape of a site tobe constructed; then, a size table of the movable wheel and the fixed wheels of the arcing machine is calculated according to the radians and the radiuses; the arc pipes needed by the site to be constructed are machined according to the size table of the movable wheel and the fixed wheels of the arcing machine; the arc pipes are connected, and fixed brackets are added; and the constructed arc pipes are tested and detected. The method adopts mechanical arcing to solve the quality defects in a traditional arc pipe construction process, and improves the construction mechanical degree and the construction quality.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a mechanized arc-shaped pipeline construction method. Background technique [0002] There are two processing methods for traditional curved pipes. One is to cut the pipe into short sections of about 2 meters, and install the curved pipes in the form of fittings. This method not only increases the number of clamp connectors used, but also increases the engineering volume of pipe cutting and grooves, resulting in labor waste and increased construction costs. In addition, too many interfaces and a large number of pipe fittings can easily cause hidden dangers of pipeline leakage. [0003] The other is to use the method of manual top bending, that is, to carry out segmental (at least three sections) simultaneous top bending of the pipeline that has been divided into fixed lengths on site, and to use the self-made ground fixing bracket to carry out the top bending of the...

Problems solved by technology

This construction method is completely dependent on manual operation. As the amount of work increases, the number of labor required will also increase, and the increase in labor will inevitably lead to an increase in production costs.

Due to the large differences in the degree of construction personnel's mastery of the process, the use of bending equipment, and their own abilities, even the same batch of pipes will have large arcs, arc uniformity, and overall aesthetics after bending. The difference between different curved pipes in actual construction is not only unsatisfactory in appearance, but also difficult to guarantee the safety of installation.
