Drag reducing agentInstallation instructions:

1Dig trenches according to the design length and orientation on the design drawings: depth0.8-1.0mThe size of the horizontal grounding body wrapped with drag reducing agent is generally150-200*100-150；

2Place the horizontal grounding body (flat steel or round steel, etc.) into the trench, weld it according to the design requirements, and perform anti-corrosion treatment after welding;

3Support the horizontal grounding body with a support to facilitate the wrapping of the slurry;

4．Press the drag reducer and water together2：1Mix the mixture evenly in a bucket truck or other container to form a slurry, then pour it evenly into the trench and wrap it around the horizontal grounding body. The thickness of the coating should not be less than30mm；

5．After the initial solidification of the slurry, backfill the fine soil layer and compact it;

6．Backfill the original soil layer and compact it;

7．Regarding the lead out line, the part leading out to the ground should be wrapped with a resistance reducing agent as much as possible (at least at the end close to the ground grid)50mmThe long part is buried in the drag reducing agent.

Recommended dosage：Burial of horizontal grounding body: trench width0.25～0.3m, deep0.8～1.0mThe filling cross-section of the drag reducing agent is wide0.15～0.2m, thick0.1～0.15mThe dosage is20～30kg/m。
