Problems solved by technology

[0004] RTR pipes, that is, thermosetting resin pipes, are mainly used in petrochemical systems, oil and sewage pipeline systems, domestic wastewater pipeline systems, drinking water pipeline systems, raw water pipeline systems, and discharge pipeline systems; the production of RTR pipelines in my country is developing rapidly, and the number is increasing year by year. And the department is getting wider and wider, but most of the pipes are installed in the country using laminated winding connections, and the installation experience is relatively weak, and there are many quality defects in the on-site installation, which has caused certain obstacles to the popularization and promotion of pipes

Embodiment

[0079] A construction method of a thermosetting resin pipeline in desert soil, characterized in that it comprises the following steps:

[0080] Construction preparation:

[0081] 1) Prepare the materials and equipment required for construction, including pipe beveling machine, electric cutting machine, electric sanding machine, rubber leather hammer and wooden square, manual rope tightener, electric heating blanket, dust cleaning rag and morning brush, Guarantee tape, spirit level and oil-based pen, glasses, gloves and masks, etc.;

[0082] 2) Check and organize the pipes and fittings, place the pipes and fittings in a cool and well-ventilated place, and do not come into direct contact with the ground, so as to prevent the pipes from being damaged by collision during storage;

[0083] 3) When hoisting, use nylon rope for hoisting. When placing along the pipeline, the lower part of the pipeline should be padded with supports. Block the mouth of the pipe to prevent sand and du...

Abstract

The invention discloses a construction method for a thermosetting resin pipeline in desert soil. The construction method comprises the steps of pipeline and pipe fitting acceptance inspection, pipeline and pipe fitting treatment, inventory and storage, RTR pipeline ditch excavation, pipeline ditch bottom acceptance inspection, pipeline bonding installation, pipeline laying, pipeline pressure testand leakage test performance test and road section passing pipeline construction. The RTR pipe construction procedure and the method are improved and innovated; a set of mature, efficient and convenient installation method is formed by adopting a beveling machine centralized turning beveling process, a prefabricated field pipe centralized process pre-assembling pipe fitting, a bonding process improvement process and an RTR pipe convenient tightness test process, the installation period is shortened, the engineering quality is improved, the construction cost is saved, and good economic and social benefits are obtained.
