Cast-iron well builds attaint to have what reason and the way to deal with a situation

Lid of well of nodular cast iron is the lid of a kind of well with wide now application, but as a kind often wind blows insolation, reach the product of laden weigh, still can various reasons bring about a well to cover damage, case study is below:

1, well lid is corroded by the aeriform institute in the well, the well builds shell of minute of heating power well, offer well to build, telegraphic well is built, village well is built, bilge well lid, if the gas below is caustic particularly big, can be corroded by gas, chloric ion exists in the environment especially: Chloric ion exists extensively, for instance salt, sweat mark, seawater, sea wind, soil is waited a moment. Well lid is put in the environment below in chloric ion, corrode very fast, exceed common mild steel even. The use environment that builds to the well so has a demand, and need often is wiped, eliminate dirt, keep clean and dry.

2, well is built by make friends bad one of common causes that also are attaint. The car on the road is increasing now. Be in especially big city, if do not have a kind waterproof, guard against theft, prevent shake, the well lid of antirust corrupt is used on the driveway, its result or driveway black hole are increasing.

3, the material that production well builds is very important. Want to cast well lid with good stuff, cannot not accord with scientific data to replace with a kind casually, be like composite material, cement, water chestnut magnesian earth. The well lid of these material make it does not fight ageing, not impulse withstand, time grows to be able to damage automatically. These wells build in-house framework having steel, can get rich to a few illegal person pilfer offer an opportunity. Cause a loss to the country thereby. High-tech technology cannot not reclaim the material of value makes well top. It is high-tech technology there is very great pressure in development, this kind of technology also cannot be used on the composite material of be there just to make up the number to make well top.

The analysis gave a reason to find out countermeasure easily, the method that puts an end to a well to cover damage is very simple, it is to make sure eligible product puts in the market, 2 it is to often be overhauled, one discovery has bad evidence to change immediately.
