The excavation width and depth of carbon pipe trenches should be determined by the number of rows of pipe layers. The distance between the top of the pipe and the ground should generally not be less than 1.
Direct burial generally does not require foundation treatment, just digging trenches and burying directly. Since the sheathed pipe has good integrity, it is advisable to bury it directly in general areas. The distance between the top of the pipe in the load area and the ground should generally not be less than that.
Concrete encapsulation for fast lanes and heavy load areas. The safer way is to encapsulate concrete. When encapsulating concrete, the bottom of the ditch must be treated. Generally, yellow sand or concrete cushion is laid and compacted and leveled. The distance between pipes is not less than 100 meters and the gap between pipes is from bottom to top. Compact layer by layer. When starting the vibrator, pay attention to fixing the pipes with pipe pillows (pipe pillows are generally built with bricks).
Carbon pipe
Pipe laying (pipe laying)
Place the pipe on the laying frame.
Loosen the wire at one end of the pipe (be careful that the wire curls into the pipe).
Lay the pipes in circles one by one and lay them in the trench to prevent debris from entering the pipes during laying. For pipelines laid in multiple layers, the method of laying pipes layer by layer from bottom to top is generally adopted.
For pipes exposed to the ground, they must be covered with pipe caps in time to prevent foreign matter from entering.
Connection of carbon pipes
Simple spiral connection is used. The company has professionally prepared spiral joints.
If you are more particular about it, you can use a spiral joint to heat the plastic sleeve to achieve a sealed connection.
The iron wire in the pipe should be connected to the pipe at the same time.
Carbon pipe filling
Fill in the surrounding soil layer by layer around the pipe and compact it firmly.
Concrete encapsulation is generally tamped with a vibrator, and small stones are sufficient for the concrete. After the concrete has set, it is filled with soil.
Carbon pipe threading
The steel wire rope is pulled by the iron wire embedded in the pipe, and then the cable is pulled by the steel wire rope. In the following, the cable can be directly pulled by the iron wire
