Abstract
Description
Technical Field
[0001] The utility model relates to a pipeline butt joint structure system, in particular to a socket-and-spigot type pipeline symmetrical traction butt joint structure system. Background Art
[0002] When carrying out pipeline construction, it is necessary to extend the pipeline. For precast concrete pipelines, a socket-and-spigot joint structure is usually used. In order to improve the sealing performance of the joint, a sealing ring is set at the socket port, and a certain thrust is applied to the pipeline segment to squeeze the sealing ring to achieve a better sealing effect. During on-site construction, the pipe segment to be installed is generally pushed by the grab bucket of the excavator or other machinery and equipment, which is not only easy to damage the pipeline port, but also difficult to apply to the pipeline segment with large structural size and weight. In order to ensure the smooth docking of the pipeline, the engineering and technical personnel tied the traction rope on the pipeline and pulled the adjacent pipelines through the winch, hand winch and other equipment to complete the docking operation. There are some problems with this method. The traction rope is directly wrapped around the pipeline, which is easy to slip off the pipeline during traction, and after the traction operation is completed, the traction rope is pressed under the pipeline and is difficult to remove quickly; the traction operation usually adopts a unilateral traction method, which is easy to cause the pipeline axis to deflect and cause uneven force on the socket, resulting in rupture at the socket port.
