Abstract
The invention relates to an embedding method of an inclinometer and sedimentation pipe. The method comprises the following steps of: sleeving a protection pipe outside an inclinometer and sedimentation pipe, wherein the internal diameter of the protection pipe is larger than the joint external diameter of the inclinometer and sedimentation pipe by at least 50mm; filling medium sand or fine sand in the gap between the protection pipe and the inclinometer and sedimentation pipe; then, building a fine particle material pile with the height of 1-1.2m and the diameter of 1.5-2.0m outside the protection pipe; and along with the lengthening of the inclinometer and sedimentation pipe, continuously pulling the protection pipe upwards until the inclinometer and sedimentation pipe is lengthened and heightened to a designed height. The embedding method of the inclinometer and sedimentation pipe not only can overcome the defect of the traditional non-pit-type embedding method that the inclinometerand sedimentation pipe is easy to damage, but also can overcome the defect of a pit-type embedding method that building materials need to dig with great difficulty every time the inclinometer and sedimentation pipe is lengthened, thereby improving the embedding quality and the embedding work efficiency of the inclinometer and sedimentation pipe in engineering.
