Problems solved by technology
[0003] However, when welding the insulating tubes, only the rubber that is heated and melted by the contact surface is connected, so that the connection strength of the two insulating tubes is weak. When the two insulating tubes are displaced to different degrees, cracks are prone to occur at the joint Or disconnected, and once there is a gap at the connection, the insulation strength of the insulating tube will be destroyed

The invention discloses a welding-reinforced underground insulating pipe and a method for using the same, belonging to the field of insulating pipe industry. A welding-reinforced underground insulating pipe comprises an insulating pipe body and a heater corresponding to the insulating pipe body, and the insulating pipe body One end of the insulation pipe is fixedly connected with multiple reinforcements, and the multiple reinforcements are distributed in a ring. The other end of the insulating pipe body is cut with multiple positioning slots matching the reinforcements. The positioning slots include horizontal slots and vertical slots, and the vertical slots pass through the horizontal The groove communicates with the outside world, which can be realized on the basis of heating and welding. By setting reinforcements and positioning grooves, the strength of the joint can be increased, and through the coagulation of the solidifiable liquid and the thorn point, the thorn point can be extended into the limit hole to reduce the The detachment probability between the two insulating tubes can also use the effect of solidification after the solidifiable liquid flows out and fills the positioning groove, which improves the connection effect again, and strengthens the connection between the insulating tubes through multiple connections.
Description
technical field [0001] The invention relates to the field of insulating pipe industry, and more specifically relates to a welded and reinforced underground insulating pipe and a use method thereof. Background technique [0002] The insulating tube is made of non-alkali glass fiber tube coated with modified polyvinyl chloride resin and plasticized. It has excellent flexibility and elasticity, as well as good dielectric properties and chemical resistance. At present, due to the long length and large diameter of insulating pipelines used underground, in order to facilitate transportation and production, the length of such insulating pipes is usually limited. In practical applications, it is necessary to connect multiple insulating pipes to the required length. The gap between adjacent insulating tubes makes the insulation effect better. Generally, welding heating is used. The specific operation is to use a heater to heat the contact surface of adjacent insulating tubes. After t...
