HDPE pipe construction technology
Nov 24, 2017

(1) HDPE pipe thermal expansion and contraction serious, so HDPE pipe should be little change in the temperature difference between the construction and use.

(2) Where the HDPE pipe is buried at a depth below the base of the foundation of the structure, the pipe shall not be located within the range of the foundation diffusion angle under the foundation of the structure.

(3) Where the groundwater level is higher than the bottom elevation of the trench, the groundwater level will drop 0.3m ~ 0.5m below the nearest point of the bottom of the trench.

(4) During trench excavation, the depth of excavation shall be strictly controlled and the undisturbed foundation soil shall not be disturbed. In the event of over-excavation and disturbance, natural graded aggregate with a grain size of 0.1 m to 0.5 m shall be exchanged for filling and compaction.

(5) The foundation of HDPE pipe is grit foundation instead of concrete foundation with a thickness of 0.05 m ~ 20 m, depending on geological conditions.

(6) pipe laying process, the lower pipe by artificial or crane, under the crane pipe, with non-metallic rope fasten pipe ends away from the nozzle 1/4, is prohibited through-core hoisting.
