The flexible PTFE tube is used to bury the protective equipment, leaving enough space nearby, which will not affect the rubber joint displacement function, and can make the PTFE pipe and the external filling block, and also make the sturdy sliding device two tubes. There is no resistance, so the pipeline equipment on the backfill is flat. Cars accumulate heavy objects or equipment are not affected. The PTFE pipe floor equipment has two semi-circular hollows. The rubber head and the pipe flat welding flange all enter the body. Two small semi-circular aircraft are installed at both ends to ride the flange outer walls on both sides. The vertical surfaces of the two heads support the foundation depth. , enough to accept external pressure load.

    The number of equipment must be matched to the locking bolt device. Method equipment: PTFE pipeline equipment, PTFE pipeline protection equipment, asphalt coating anti-rust coating, reduce 1/2 protection equipment in the upper 1/2 protection device, lock bolt tightening convolution (note the equipment in an intermediate bearing PTFE Pipeline equipment protection equipment asphalt coating anti-rust paint, PTFE pipe backfill, beating, solid tri-string and cushion, laying the ground (preferably having a permanent symbol in the proper position, in preparation for the next point of view, ie position Replace when).
