Telecom Manhole Chamber- On-site Construction Process

FCST Full Series -Telecom Manhole Chamber

Construction Process

1. Dig the roadbed 

Before the construction, determine the depth of the Manhole Access Chamber buried, determine the well location, break the pavement structure, dig out the soil, the edge of the foundation pit using artificial chisel, to ensure that the edge of the foundation pit neat, smooth, solid. 

2. Pour cement 

Clean the bottom of the foundation pit, infiltrate the bottom with water before pouring, and pour a layer of concrete to prevent settlement. The dimensions of the bottom edge of the Cable Duct Access Manhole Chamber with the length to width ratio of concrete are 150mm and the thickness is 50-100mm.

3. Lay gravel layer 

Gravel is laid on the concrete, and the thickness of gravel is about 50mm, which is convenient for the water in the Manhole Chamber to exit.

4. Install the Manhole Chamber 

After the main body of the Manhole Chamber is assembled, put it into the pit position smoothly, and adjust the height of the top surface of the well seat to be flush with the ground elevation.

5.Manhole Chamber opening and threading 

Select an appropriate alloy hole opener according to the size of the thread to be threaded in the side wall of the Manhole Chamber, and then thread.

6. Backfill

Backfill the excavated soil or sand into the well pit, and use a tamping machine to tamp the backfill soil. (See installation for the elevation of the compacted backfill from the ground Schematic diagram)
