Embodiment 1

[0037] Such as figure 1 , figure 2 with image 3 The shown prefabricated pipeline maintenance well with anti-corrosion function includes a steel maintenance well body 1 with a hollow structure. The upper end of the maintenance well body 1 is provided with a well neck 2. There is a well cover 10 for closing the wellhead 3 at the upper end of the well neck 2. The side wall of the maintenance well body 1 is provided with two reserved pipes 6, and one end of the two reserved pipes 6 is connected to the maintenance shaft body. 1 is connected, the side wall of the maintenance well body 1 is provided with a casing 4, and the casing 4 is provided with a threading pipe 5 for leading out the lines of each equipment in the maintenance well body 1; the maintenance well body 1 The outer surface of the outer surface, the outer surface of the well neck 2, the outer surface of the well cover 10, the outer surface of the reserved pipe 6, the outer surface of the casing 4 and the outer surfa...

Embodiment 2

[0060] The difference between this example and Example 1 is that the low-temperature-resistant solvent-free thick-film epoxy anticorrosion coating is prepared by uniformly mixing component A and component B in a weight ratio of 4:1.

[0061] In this embodiment, the A component contains the following components by weight: 100kg composite toughened epoxy resin, 20kg anti-dripping gel, 50kg precipitated barium sulfate, 10kg iron oxide red, 40kg sericite, 30kg talcum powder, Germany Bi Ke BYK-A530 defoamer 4kg, German Bi Ke BYK-3550 leveling agent 4kg; Described composite toughened epoxy resin is the polypropylene glycol ether polyurethane prepolymer ( Bayer XP2540) is mixed according to the weight ratio of 100:10; The anti-dripping gel is made according to the weight ratio of 8:5:30:100 by silane coupling agent KH550, fumed silica, nano-titanium dioxide and composite epoxy resin Prepared by mixing; the composite epoxy resin is made by uniformly mixing bisphenol A epoxy resin E51 ...

Embodiment 3

[0073] The difference between this example and Example 1 is that the low-temperature-resistant solvent-free thick-film epoxy anticorrosion coating of this example is prepared by uniformly mixing components A and B in a weight ratio of 3:1.

[0074]The A component contains the following components by weight: 100kg of composite toughened epoxy resin, 50kg of anti-dripping gel, 50kg of precipitated barium sulfate, 50kg of talcum powder, and 5kg of German BYK-A530 defoamer; Tough epoxy resin is made by mixing composite epoxy resin and toughening agent polymerized phenol-terminated polypropylene glycol ether polyurethane prepolymer (Bayer XP2540) in a weight ratio of 100:50; the anti-dripping gel is made of silane coupling agent KH560, fumed silica, nano-titanium dioxide and composite epoxy resin are mixed according to the weight ratio of 10:10:5:100; the composite epoxy resin is made of bisphenol A type epoxy resin E44, bisphenol F type Epoxy resin 170 and polypropylene glycol dig...

Abstract

The invention discloses a prefabricated pipeline overhaul well with a corrosion prevention function. The prefabricated pipeline overhaul well comprises an overhaul well body. A foreshaft is arranged at the upper end of the overhaul well body. A well lid is arranged in the foreshaft. Two reserved pipes are arranged on the side wall of the overhaul well body. One end of each reserved pipe communicates with the overhaul well body. A sleeve is arranged on the side wall of the overhaul well body. A conduit is arranged in the sleeve. The outer surface of the overhaul well body, the outer surface of the foreshaft, the outer surface of the well lid, the outer surfaces of the reserved pipes, the outer surface of the sleeve and the outer surface of the conduit are all coated with corrosion-resistant paint. The overhaul well body of the pipeline overhaul well is made of steel instead of bricks or concrete, so that long-term immersion of underground water is effectively resisted, and the seepage phenomenon is effectively avoided; the overhaul well body is prefabricated, and thus the construction period is greatly shortened; and in addition, corrosive components in backfilled earth and corrosive components in the underground water can be effectively prevented by the overhaul well, and the good corrosion prevention function is achieved.

Description

technical field [0001] The invention relates to a maintenance well, in particular to a prefabricated pipeline maintenance well with anti-corrosion function. Background technique [0002] The maintenance well (valve well) is an important subsidiary structure to ensure the normal operation of the pipeline system. The traditional maintenance well is a brick structure (or brick-concrete structure), which is built on the construction site and has a long construction period. Because the main material of the structure is red brick or concrete, it cannot resist the long-term immersion of groundwater, and water seepage often occurs, making it inconvenient for the staff to control the equipment in the well, and the equipment and facilities in the well are often corroded and damaged due to water seepage. How to design a maintenance well that can effectively solve the water seepage problem and achieve effective anticorrosion is a technical problem to be solved urgently by those skilled ...
