Improved settlement and load-bearing characteristics<\/strong><\/p>\n<\/div> The ultimate capacity of pile can be enhanced by grouting shaft after it has been constructed<\/strong><\/p>\n<\/div> Grout is injected at high pressure through the TAMs into the ground to consolidate the soil\u2019s characteristics. Soletanche Bachy has its own in-house control system, called SPICE.<\/p>\n<\/div> Our processes<\/p><\/h2><\/div> Fabric pipe<\/strong>: A sleeve pipe (tube \u00e0 manchette) will be incorporated into reinforcement cages. The sleeved have smooth internal surface and perforations covered by rubber, which act as non-return valves.<\/p>\n Water cracking<\/strong>: 12 hours after concreting pile, the sleeves are cracked using high-pressure water.<\/p>\n Mixing<\/strong>: Mixing of cement grout ingredients are conducted in the following orders: Water-Bentonite-Cement-Admixtures.<\/p>\n Grouting<\/strong>: Proceed after at least 5 days since the completion of concreting. Start from the lowest manchettes. Grout is injected by PH2\u00d75 pumps until the stopping criteria are met.<\/p>\n<\/div><\/div><\/div>
