What are the construction methods for cement manholes?
Construction methods for pre-mixed well.
Load-bearing capacity over 100kg/m², with a 1000mm thick gravel layer laid underground.
The product's shape is available in circular and rectangular frames. The standard pipe interface is the bending rigidity sleeve. The pipe end features a soft socket for connecting to the drainage inspection well.
Connect concrete components, inspect if the pipeline is level. Connect the precast manhole's rain downpipe to the embedded component hole by adjusting the height of the connection to the main pipeline.
Considering different backfill thicknesses, the well house is composed of one well circle and seven adjustable blocks of varying heights. The diameter of the φ700 circular well is the same as that of the rectangular frame well.
Pre-manufactured inspection wells and pipe plugs should have burrs removed. During wiring, use 1:2 cement mortar water or PU mixed cement mortar. Water flow should be between 20%-50%, and wiring thickness should be 10-15mm. When selecting other pipes (such as plastic pipes), follow their specific pipe requirements.
