Metallurgy, CNC Machining & Quality Infrastructure
Engineered to withstand millions of severe dynamic compaction cycles without structural fatigue or dimensional deviation.
Monolithic Monolift Pouring Tooling
Base slab and cylindrical walls are poured simultaneously in a single continuous pour, eliminating cold joints and ensuring 100% watertightness.
Integrated Baffle Wall Forming
Internal steel partition inserts cast internal dividing baffle walls with integrated hydraulic transfer pipe holes in one operation.
Hydraulic Four-Direction Shrink Core
Inner core collapses inward along four diagonal sliding tracks via hydraulic cylinders, enabling fast frictionless crane extraction.
Heavy Structural Outer Locking Rings
Outer split formwork is banded by forged steel ring ribs and heavy cam-clamps to withstand full hydrostatic liquid head of concrete.
Complete Production Line Workflow & Curing Cycle
From aggregate batching to final hydraulic testing, our turnkey engineering ensures high output with minimized labor headcount.
Internal Core Setup & Release Coating
Collapsible inner core is expanded and sprayed with non-stick release agent.
Dual Rebar Cage Positioning
Cylindrical steel cage with reinforced bottom grid is lowered over the expanded core.
Outer Formwork Clamping & SCC Pour
Outer shuttering is closed; high-slump impermeable concrete is poured with high-frequency external vibration.
Hydraulic Core Contraction
After concrete achieves initial hardening, hydraulic valves activate to shrink the inner core 50mm inward.
Outer Formwork Release & Yard Storage
Outer shell unlatches; overhead gantry crane lifts completed monolithic septic tank onto the curing storage yard.
Standard Turnkey Production Line Scope of Supply
We deliver fully integrated plant packages including mechanical host, electrical VFD console, hydraulic station, and civil foundation blueprints.
Primary Engineering Applications
