Abstract
A well-type installation cathode protection test pile is used for urban gas pipeline cathode protection parameters. In order to prevent an overlong test pile from being exposed out of ground, hampering urban landscape and being damaged, a test column together with a wiring board installed thereon is vertically installed into a test well with a well cover. The test column is a telescopic columnar structure formed by single section, or two sections or pluralities of sections; the test well is fixedly installed on a concrete foundation; the concrete foundation together with the test well installed thereon is vertically buried under a ground surface, but the well cover of the test well is exposed out of the ground; and the test well and the well cover are locked by a well cover lock after the well cover is closed.
Description
Technical field
The utility model relates to a kind of cathodic protection test pile, and especially the well formula is installed cathodic protection test pile.
Background technology
At present, known cathodic protection test pile is made up of terminal block, test cable, test pole and concrete foundation.Test pole is the column tubular structure, terminal block is installed in the terminal box of test pole upper end or is installed in the pipe of test pole epimere, test pole is fixedly mounted on the concrete foundation, the hypomere and the concrete foundation of test pole are embedded in below ground, and the most of length of the epimere of test pole is vertically revealed sky more than ground.One end of test cable is installed on the terminal block by binding post, after the other end of test cable passes test pole, introduces and undergroundly is connected with pipeline or sacrificial anode.
When carrying out the cathode protecting parameter test, door direct anticathode protection parameter on terminal block that the tester opens on the test pole is measured.
But when cathodic protection test pile was arranged in the cities and towns, what its test pole of big section was vertical was exposed at more than the ground surface, both has been an impediment to urban look, is easy to again be damaged.
Summary of the invention
Be an impediment to urban look and be easy to impaired deficiency in order to overcome existing cathodic protection test pile, the utility model provides a kind of well formula that cathodic protection test pile is installed.
The technical scheme that its technical matters that solves the utility model adopts is: an end of test cable is connected on the terminal block by binding post, terminal block is installed in an end of test pole, the other end of test cable is introduced underground, test pole together vertically is incorporated with in the testing well of well lid together with the terminal block of installing on it, the terminal block end up and the other end of test pole is downward, testing well is fixedly mounted on the concrete foundation; Pack into the test pole lower end of testing well is fixedly mounted on the bottom surface of testing well or directly is fixedly mounted on the concrete foundation, concrete foundation vertically is embedded under the ground surface together with the testing well that is installed on it, but the well lid of testing well bassets, and can be by the pattern manhole cover lock locking between testing well and the well lid.
The test pole of installing in the testing well is non-telescoping single-unit column structure, or the telescopic column structure of two joints or more piece composition.After tester's test jobs finishes, close well lid and sealed pattern manhole cover lock, avoid testing well water inlet or detective pole to be damaged, but can the shut-in well lid after should shrinking pillar to telescopic test pole.
The beneficial effects of the utility model are, use the well formula that cathodic protection test pile is installed in the cathodic protection system of city gas pipe network, and arrangement convenience under the situation that does not hinder urban look also is difficult for being damaged after installing well lid additional, and the life-span is long.
