To decrease the possibility of lateral deformation and provide a lasting solid protection to the reinforced structure.
To enhance the draining function of the structure.
To separate different materials and provide certain degree of draining and filtering functions to the structure for overall stability.
To reinforce and stablize the structure with the designed strength.
Clean the ground surface of the site, and excavate in accordance with the levelling layout. Then compact the ground to the required compactness.
Set up formwork and cast the RC foundation specified on the design drawing for the segmental precast concrete panel.
Install the precast concrete panels on the RC foundation with crane, and insert steel bars to the reserved holes on each panel to connect adjacent panels.
Cut ACEGrid® to the size specified on the design drawing (including at least 2 meters in length for wrap-around purpose). ACEGrid® should be laid flat without any corrugation. Anchorage should be done with the anchorage interval specified on the design drawing. The length of ACEGrid® that wraps around should be properly connected to the hooks on the concrete panel and fixed with hardware.
Fill soil bag with fine aggregate and cross stack behind the panels to the designed height, in order to reduce the pore water pressure in the backfilled area.
Backfill soil at the back of the sand bag facing; the thickness of every layer should be between 15 cm to 30 cm. Then, perform compaction from the facing inward to the backfill area to meet the required compactness specified on the design drawing.
Repeat step 3 to 6 to achieve the required height specified in the design drawing.
After achieving the designed height, cap the concrete panel wall by casting a concrete capping.
Segmental Precast Concrete Panel is completed.
