Adjustable temporary support for installation of constructional engineering pipeline

The utility model relates to a constructional engineering pipeline installation adjustable temporary support which comprises a plurality of stand columns with clamps, each stand column with the clamps is symmetrically provided with a plurality of clamp hoops capable of adjusting the height and the direction, support cross arms are erected between the clamp hoops, and each clamp hoop comprises a hoop plate installed on a steel pipe. A clamp body for bearing a bracket cross arm is arranged on the hoop plate, and a clamping mechanism capable of clamping the bracket cross arm is arranged on the clamp body; the method has the advantages that multiple professional pipelines can be pre-installed at the pipeline mixed intersection point at the same time, the installation construction progress is greatly improved, after it is ensured that the installation effect of the BIM building model is achieved, the permanent support is pre-installed, the installation height and angle of the pipelines are adjusted in real time, a
