Abstract
The invention relates to a manufacturing method of cable butt joints, in particular to a manufacturing method of butt joints of elongated cables for geotechnical engineering instruments. The manufacturing method includes steps of cable roughening, use of an inner thermal-shrinkage sleeve, fitting use of self-adhesive tape and use of an outer thermal-shrinkage sleeve. The manufacturing method of the butt joints of the elongated cables for the geotechnical engineering instruments has the advantages that materials are easy to be prepared, manufacturing is simplified and in-situ manufacturing of joints for engineering is easy to realize, and is quite suitable for manufacturing the joints of the elongated cables for the geotechnical engineering instruments on sites. Besides, the cable butt joints manufactured by the manufacturing method are compact in structure and high in water pressure resistance and reliability.
Description
Technical field
The present invention relates to a kind of manufacture method of cable butting joint, particularly relate to a kind of Geotechnical Engineering instrument jumper banjo fixing butt jointing manufacture method.
Background technology
The Geotechnical Engineering construction tends to bury underground a large amount of monitoring instrument (transducer) and is used for status monitoring.The cable joint quality of connection quality of these monitoring instruments (transducer) is to guarantee one of important step that can the engineering monitoring system long-time running.And cable joint generally is again the weakest link in the whole monitoring system system.Although monitoring instrument through various verification tests can guarantee its imbed before no any quality problems, do not pass a test if handle because of cable connection joint, instrument is operate as normal for a long time still, so cable quality of connection difference usually becomes a major reason of instrument inefficacy.
Can verify that according to long-term practical experience most mainly is not that cable joint lost efficacy and causes to the sensor failure of design service life.Therefore, guarantee the cable joint quality, the stable operation of monitoring system is had very big meaning.
Cable joint is made at present generally has two kinds of methods:
First kind, after the cable core strip off is docked as requested, carry out the insulation between each heart yearn, generally adopt little heat-shrinkable T bush to entangle the pyrocondensation insulation.At whole joint coated outside Hot melt adhesive tape, the heat-shrinkable T bush that the Hot melt adhesive tape outside puts suitable size evenly heats to heat-shrinkable T bush and Hot melt adhesive tape with heat gun or flatiron, by the time after the Hot melt adhesive tape fusing, have glue from heat-shrinkable T bush, to overflow and get final product.The horizontal positioned joint treats that whole joint cools off the making of promptly having accomplished joint.This method also has direct employing band PUR heat-shrinkable T bush to make.Operate same as described above basically.
Second kind, after the cable core strip off is docked successively, carry out the insulation between each heart yearn.Twine as requested with electrical adhesive tape in whole joint outside then.
The prior art shortcoming: PUR is not strong to PVC cable adhesion, embrittlement easily.Ready-made cable joint is very fragile unreliable, and bending is arranged slightly, reverse etc. all makes PUR and PVC cable throw off easily, makes joint can not reach waterproof effect.And when constructing at the scene, instrument cable is often to need to move, bending, wear action such as pipe.This has also caused the inefficacy of a lot of water joints.Cause installing the instrument buried underground because cable former thereby can not use.
Summary of the invention
Main purpose of the present invention is to provide a kind of new Geotechnical Engineering instrument jumper banjo fixing butt jointing manufacture method, and it is not enough to overcome employed PUR adhesion power, the insecure shortcoming of the joint of made.Ready-made joint can also have good reliability by random movement.
Major technique of the present invention thes contents are as follows:
A kind of Geotechnical Engineering instrument jumper banjo fixing butt jointing manufacture method may further comprise the steps:
