The pressure-resistant and corrosion-resistant PE water supply pipe suitable for a deep buried environment disclosed in the utility model can resist pressure by means of a pressure-resistant outer pipe assembly sleeved thereon, and a movable flange 4 is detachably installed at the end of the PE water supply pipe body 1, so that the pressure-resistant outer pipe assembly is easy to disassemble, has a strong pressure-resistant effect, is easy to disassemble, replace, and overhaul, and has a long service life.

[0019] Furthermore, the outer pressure-bearing pipe 7 is fixedly connected to the outside with an anti-corrosion layer 8, and the anti-corrosion effect is good; further, the outer wall of the other end of the PE water supply pipe body 1 is provided with an external thread 3 and a movable flange 4 is detachably installed through the external thread 3 and the internal thread 5, and the inner wall of the movable flange 4 is provided with an internal thread 5, which is convenient for disassembling and assembling the movable flange 4; further, the root of the support bar 9 is fixedly connected with an inner tube 10 and fits the outer wall of the PE water supply pipe body 1 through the inner tube 10, and the inner tube 10 at the root of the support bar 9 increases the pressure area, reduces the pressure on the PE water supply pipe body 1, and further protects the PE water supply pipe body 1; further, the support bar 9 is made of PE material, and the outer pressure-bearing pipe 7 and the inner tube 10 are both made of metal material, which are not easily damaged after being under pressure.

[0020] In the present solution, when in use, the pressure-resistant and corrosion-resistant PE water supply pipe suitable for a deep buried environment disclosed by the utility model can resist pressure by means of a pressure-resistant outer pipe assembly sleeved outside the pipe, and a movable flange 4 is detachably installed at the end of the PE water supply pipe body 1, so that the pressure-resistant outer pipe assembly is convenient to disassemble, has a strong pressure-resistant effect, is convenient to disassemble, replace, and overhaul, and has a long service life. The pressure-resistant and corrosion-resistant PE water supply pipe for a deep buried environment is subjected to greater pressure due to being buried deep underground. When subjected to pressure, the outer pressure-bearing pipe 7 is subjected to pressure first, and since the inner side wall of the outer pressure-bearing pipe 7 is in a circumferentially equidistant array and is fixedly installed with a plurality of support bars 9 that play a supporting role, the plurality of spaces separated by the plurality of support bars 9 can act as a buffer The effect is that the outer pressure-bearing pipe 7 can have a certain deformation space after being compressed and deformed, and will not be squeezed to the PE water supply pipe body 1 immediately, and the support bar 9 plays a supporting and pressure-resistant role, and the pressure-resistant effect is good. The root of the support bar 9 is fixedly connected with the inner tube 10 and the inner tube 10 fits the outer side wall of the PE water supply pipe body 1.

When the pressure-resistant outer tube assembly is crushed, the movable flange 4 can be unscrewed to replace the pressure-resistant outer tube assembly, which is convenient for replacement and maintenance.
