Abstract
The invention discloses a manufacturing method of a high-corrosion resistance manhole cover. The manufacturing method of the high-corrosion resistance manhole cover comprises the steps of selecting materials, performing annealing, arranging an inner annual pipe around a manhole cover, performing grinding, performing anti-seepage treatment, spraying a wear-resistant coating, and the like. Through reliable processing techniques, anti-freezing processing of a manhole ring is realized. The overall structure of the manhole cover is more reliable.
Description
Technical field
The present invention relates to well hole auxiliary device field, specifically a kind of manufacture method of highly corrosion resistant well lid.
Background technology
Currently, with the development of the city and road reformation, a large amount of communications for arranging on the ground, power cable etc. are required for
Underground is moved on to, is re-started and is laid.In the future these facilities are safeguarded and changed for convenience.So being accomplished by building a large amount of
Inspection shaft meeting the needs that engineering maintenance in the future and maintenance are changed.The appearance of these inspection shafts, really to maintenance in the future and
Maintenance is changed there is provided great convenience.But in the winter time, the particularly more cold area of weather, under Snowfall, well lid
Easily freeze with the junction of walling crib, when run into line fault need open well lid overhauled when, in addition it is also necessary to ice sheet is smashed to pieces,
Ability breakdown well lid, if ice sheet is thicker, the ice sheet covered on well lid is thicker, is difficult to smash to pieces, and overexerts, it is also possible to cause
Well lid Integral-crushing.
The content of the invention
The present invention is intended to provide a kind of manufacture method of highly corrosion resistant well lid, to solve the above problems.
For achieving the above object, technical scheme is as follows：
A kind of manufacture method of highly corrosion resistant well lid, it is characterised in that comprise the following steps：
Sorting：From 430 stainless steel materials as blank, Size calculation is carried out according to well lid size, then use cutting machine according to
Blank is cut by the target size after calculating；
Annealing：Plectane after cutting is placed in annealing furnace and is made annealing treatment, 1095 DEG C of annealing furnace keeping temperature, when continuing
Between 15 minutes, it is then quick to cool down；
Insert inner groove：Well lid circumference is placed in from endless tube, and carbon fiber heating silk is laid in endless tube；
Anti-seeping technology：Polystyrene is sprayed by spouting plant and is filled into the remaining space of endless tube, and by polystyrene layer reconditioning
It is smooth;
Polishing：Surface polishing is carried out, sanding burr totally and is polished；
Basecoat paint：To well lid surface spraying/roller coating prime paint, and it is dried 30 minutes；
Surface lacquer is sprayed：In prime paint surface laser spraying of wearable coating, after being dried 0.5-1.5 hours, repeat spraying three times.
Further, the wear-resistant coating thickness is 100 μm -120 μm.
Further, the well lid bottom metal material reinforcement.
Further, the reinforcement is crisscross setting.
Further, the reinforcement includes four horizontal bars and three perpendicular muscle.
The beneficial effects of the present invention is：Using 430 rustless steels, can effectively anticorrosive oxidation, it is to avoid well lid is in specific ring
The problem of the lost of life used in border, in more cold winter, by powering to carbon fiber wire, can convert electric energy to heat
Can, it is to avoid well lid and interior walling crib junction produce the phenomenons such as icing and cause well lid open.
Polystyrene packed layer is provided with, polystyrene packed layer can play a part of good waterproof and thermal insulation, it is to avoid
Heat significantly scatters and disappears, while it also avoid steam entering in the annular groove of laying carbon fiber heating silk, causes short circuit.
Specific embodiment
With reference to specific embodiment, the present invention will be further described.
A kind of manufacture method of highly corrosion resistant well lid, it is characterised in that comprise the following steps：
Sorting：From 430 stainless steel materials as blank, Size calculation is carried out according to well lid size, then use cutting machine according to
Blank is cut by the target size after calculating；
Annealing：Plectane after cutting is placed in annealing furnace and is made annealing treatment, 1095 DEG C of annealing furnace keeping temperature, when continuing
Between 15 minutes, it is then quick to cool down；
Insert inner groove：Well lid circumference is placed in from endless tube, and carbon fiber heating silk is laid in endless tube；
Anti-seeping technology：Polystyrene is sprayed by spouting plant and is filled into the remaining space of endless tube, and by polystyrene layer reconditioning
It is smooth;
Polishing：Surface polishing is carried out, sanding burr totally and is polished；
Basecoat paint：To well lid surface spraying/roller coating prime paint, and it is dried 30 minutes；
Surface lacquer is sprayed：In prime paint surface laser spraying of wearable coating, after being dried 0.5-1.5 hours, repeat spraying three times.
The wear-resistant coating thickness is 100 μm -120 μm.
The well lid bottom metal material reinforcement.
The reinforcement is crisscross setting.
The reinforcement includes four horizontal bars and three perpendicular muscle.
Using 430 rustless steels, can effectively anticorrosive oxidation, it is to avoid well lid asking of shortening of service life in specific environment
Topic, in more cold winter, by powering to carbon fiber wire, can convert electric energy to heat energy, it is to avoid well lid and interior walling crib
Junction produces the phenomenons such as icing and causes well lid open.
Polystyrene packed layer is provided with, polystyrene packed layer can play a part of good waterproof and thermal insulation, it is to avoid
Heat significantly scatters and disappears, while it also avoid steam entering in the annular groove of laying carbon fiber heating silk, causes short circuit.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
Change, equivalent, improvement etc., should be included within the scope of the present invention.
