A pipe support strut system uses struts, each having a rigid sighting member having threaded shafts extending opposingly therefrom. Each shaft is provided with a correspondingly threaded nut having steel rod handles. A pipe extends coaxially around and outward from each threaded shaft and abuts the nut threaded thereon. The pipe terminates outwardly in a base plate having flanges for retaining a wooden block or pad against the internal wall of a large-diameter, flexible pipe prior to burial thereof.
