Embodiment Construction

[0041] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. rear.

[0042] A method for manufacturing a geotechnical engineering instrument extension cable butt joint, comprising the following steps:

[0043] (1), PVC cable stripping and cable skin treatment

[0044] Such as figure 1 As shown, use wire strippers or other stripping tools to strip the cable core wires, use a file or sandpaper to file the cable skins of the two terminals that need to be connected, and then wipe with a clean rag to remove surface plastic debris and Oil pollution;

[0045] (2), butt joint of PVC cable core wire

[0046] Such as figure 2 As shown, before the core wires are connected, two heat-shrinkable sleeves with differe...

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 [0001] The invention relates to a method for manufacturing a cable butt joint, in particular to a method for manufacturing an extended cable butt joint for geotechnical engineering instruments. Background technique [0002] Geotechnical engineering construction often bury a large number of monitoring instruments (sensors) for condition monitoring. The connection quality of the cable joints of these monitoring instruments (sensors) is one of the important links to ensure the long-term operation of the engineering monitoring system. And the cable joint is generally the weakest link in the whole monitoring system system. Although the monitoring instrument has undergone various inspections and tests to ensure that there is no quality problem before it is buried, if the cable connection joint is not handled properly, the instrument still cannot work normally for a long time, so poor cable connection quality is often an important reason for instrument failure. ...
