Abstract
The invention relates to a prefabricated directly-buried anticorrosion pipeline and an installing method. At present, as various anticorrosion pipelines adopted for conveying tap water, drained water, natural gas, oil products, chemical liquid and the like do not have the intelligent monitoring function in China, leakage points can not be known accurately after the pipelines leak, the loss caused by liquid leakage is huge, and shutdown loss is immeasurable. The prefabricated directly-buried anticorrosion pipeline comprises a working pipe (4), two flat alarm cable strips (2) are installed on the pipeline outer wall of the working pipe, a groove is formed in each alarm cable strip, an alarm cable (3) is embedded in each groove, and the surfaces of the alarm cables and the surface of the working pipe are coated with anticorrosion material layers or wound with polyethylene anticorrosion layers (1). The installing method is used for installing the prefabricated directly-buried anticorrosion pipeline.
Description
technical field:
the present invention relates to a kind of prefabricated direct-buried anti-corrosion pipeline and installation method.
background technique:
the domestic all kinds of anti-corrosion pipelines adopted in conveyings such as tap water, draining, rock gas, oil product, chemical liquids all do not have intelligent monitoring function at present, after causing pipe leakage, have no way of finding out about it leakage point accurately, and the damage that leak of liquid causes is very huge, and production suspension induced losses is inestimable especially.
summary of the invention:
the object of this invention is to provide a kind of prefabricated direct-buried anti-corrosion pipeline and installation method, solve the problem that pipe leakage finds in advance, prior involvement keeps in repair, reduce the loss, planned adjustment pipeline uses, and makes loss be dropped in bottom line.
above-mentioned object is realized by following technological scheme:
a kind of prefabricated direct-buried anti-corrosion pipeline, its composition comprises: working pipe, the pipeline outer wall of described working pipe is pasted 2 flat alarm cable bands are installed, described alarm cable band has groove, be inlaid with alarming line in described groove, described alarming line and described working pipe external coating have the preserving timber bed of material or are wound around polyethylene anticorrosive coating.
described prefabricated direct-buried anti-corrosion pipeline, described polyethylene anticorrosive coating is polyethylene winding plate band.
the installation method of the prefabricated direct-buried anti-corrosion pipeline described in a kind of claim 1-2, the method comprises the steps: to paste on the outer wall of working pipe to install flat alarm cable band, alarming line is inlayed in groove on described alarm cable band, equidistant installation two alarm cables and described alarming line in every root working pipe, then at described alarming line and described working pipe external coating anti-corrosion material or be wound around polyethylene anticorrosive coating, when described working pipe is laid, after the connection of described working pipe counterpart terminates, alarming line described in working pipe described in two is carried out equidistant connection, then at described working pipe connection mouth brushing anti-corrosion material or winding polyethylene welding winding plate band, installation can be completed.
beneficial effect:
1. the present invention's cable of reporting to the police can be arranged on and anyly has anticorrosive coat or have on the pipeline of isolation layer with soil, no matter is working pipe, water pipe, plastic tube, glass working pipe etc. all can install.Need after installation to make anticorrosion and moisture barrier layers outside cable and working pipe.With primary tube trace comparison, possessed intelligent monitoring function, pipeline has been possessed anticorrosion, what extend pipeline lays working life.
2. alarming line of the present invention is arranged in the groove on alarm cable band, process of deployment is efficient and convenient, can ensure that the installation of reporting to the police is firm, has the preserving timber bed of material or be wound around polyethylene anticorrosive coating at alarming line and working pipe external coating, can effectively prevent working pipe, alarming line is corroded
3. the pipeline after the present invention's installation, alarming line connects conducting completely, and install device for signalling in a few km distance, device for signalling is connected with central control host, can complete the laying installation work of intelligent prefabricated direct-buried anti-corrosion pipeline.
4. the present invention uses intelligent prefabricated direct-buried anti-corrosion pipeline due at working pipe and pipe surface device alarming line, when there is the state of Micro blazed-grating in pipeline, can detect at once, and by alarming line, the signal of leakage point is sent to central control room, central control room is calculated through main frame, pipe leakage place can be indicated accurately, and automatically send maintenance notice instruction, pipe-line maintenance applying unit can be reached the spot and be carried out maintenance maintenance the very first time, accident is just got rid of in bud, greatly reduces causality loss.
