Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-3, a kind of novel pre-stressed cylinder concrete pipe, including first pipe 1 and second pipe 10, the first pipe The inner sidewall of road 1 and second pipe 10 is fixedly connected with connecting tube 11 jointly, and connecting tube 11 passes through multiple bindiny mechanisms and first Pipeline 1 is connected with second pipe 10, and bindiny mechanism includes logical through four first of 10 side wall of first pipe 1 and second pipe Hole 14,11 side wall of connecting tube are equipped with the second through-hole 15 being interconnected with first through hole 14, corresponding two first through hole 14 With zinc bar 13 is slidably connected in two the second through-holes 15 jointly, the center of multiple zinc bars 13 is equipped with solid rod iron, increase The intensity of zinc bar 13.

It is connected with glass reinforced plastic 12 on two ipsilateral zinc bars 13 surely jointly, 12 shape of glass reinforced plastic is arcuate shape, zinc bar 13 It is connected when through first pipe 1 and second pipe 10 with thin steel cylinder 3, reinforcing rib 5 and compressor wire 7, when moisture immerses simultaneously When contact causes thin steel cylinder 3, reinforcing rib 5 and compressor wire 7, since the chemical activity of zinc bar 13 is stronger than Steel material, when When thin steel cylinder 3,7 contact wetting of reinforcing rib 5 and compressor wire, what is corroded first is zinc bar 13, and then is protected to Steel material Shield, increases its service life, by glass reinforced plastic 12 convenient for the etch state of observation zinc bar 13, replaces zinc bar according to etch state 13, convenient for the maintenance of staff.

First pipe 1 and second pipe 10 are composite pipe, and composite pipe includes internal layer 2 and outer layer 8, internal layer 2 For third screed, the inner sidewall of internal layer 2 is coated with waterproof material 9, realizes the protection to internal layer 2, and the material of outer layer 8 is epoxy Coal tar pitch soil layer plays certain protecting effect that discharges water.

The lateral wall of internal layer 2 is equipped with thin steel cylinder 3, and the lateral wall of thin steel cylinder 3 is equipped with the first screed 4, in the first screed 4 Equipped with multiple reinforcing ribs 5, multiple reinforcing ribs 5 are staggered as annular, and the work of support is played to first pipe 1 and second pipe 10 With increasing its intensity, and then increase its service life；First screed 4 is equipped with the second screed 6, sets in the second screed 6 There is compressor wire 7, the second screed 6 is connected with the inner sidewall of outer layer 8.

In the utility model, when needing to be attached first pipe 1 and second pipe 10, connecting tube 11 is extended to In first pipe 1 and be inserted into zinc bar 13, at this time by second pipe 10 be set in connecting tube 11 lateral wall and with first pipe 1 Side wall offsets, and is inserted into zinc bar 13, realizes the connection to first pipe 1 and second pipe 10, so convenient for filling to it.

It, can be to first pipe 1 and due to being equipped with the reinforcing rib of ring mesh in first pipe 1 and second pipe 10 Two pipelines 10 play the role of support, and then increase the intensity of first pipe 1 and second pipe 10, increase its service life.

When moisture immerses and contacts the thin steel cylinder 3 of cause, reinforcing rib 5 and compressor wire 7, since the chemistry of zinc bar 13 is active Property is stronger than Steel material, and therefore, when thin steel cylinder 3,7 contact wetting of reinforcing rib 5 and compressor wire, what is corroded first is zinc bar 13, and then Steel material is protected, increase its service life, the etch state of zinc bar 13 observed by glass reinforced plastic 12, Zinc bar 13 is replaced according to etch state, convenient for the maintenance of staff, reduces economic loss.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
