Description
Technical field
The utility model belongs to trapped well field, more particularly, to a kind of trapped well system of utilization rainwater automatic water supplement.
Background technology
Design for fire protection examination ＆ verification, fire control acceptance and fire supervision checking process are being carried out to newly-built or existing construction project at present
In, it is found that considerable construction project " trapped well " designs unreasonable, many engineerings are daily in fire fighting device due to construction unit
Careless omission in maintenance management, makes " trapped well " to become " water-retention well ", once there is fire, it will cause the accident climing to other regions
Prolong, consequence is hardly imaginable.
Flammable explosive gas (methane, hydrogen) can usually be gathered in underground sewer, these gases are because " chimney is imitated
Should " played a reversed role accumulation by sewage pipe, if there is no water or water level in trapped well not enough (water seal depth is no less than 0.25m), possibility
Cause security incident, for do not set trapped well or the accident that causes of trapped well failure have occurred that it is a lot of.It is necessary design one
The set effect good automatic water replenishing system that can monitor water level easy to maintain prevents trapped well to fail, once occur accident can and
When blocking the condition of a fire ensure factory and personal security.The production waste and accident waterpipe of large chemical plant are often very long, trapped well
Distribution relatively disperses, some buried depth nearly 10 meters distant from structures, and such as connecing can be brought come moisturizing with production water pipeline to construction
Difficulty, increases material and construction cost input, and because filling pipe line length caliber is small, pressure is difficult to cause pipeline to hold, and one regularly
Cannot ensure that pipeline does not occur sedimentation, seepage and is even broken after phase, once there is pressure release, it is difficult to be sent out in daily management maintenance
It is existing, it is impossible to ensure the continuation and reliability of moisturizing, cause potential safety hazard.
The content of the invention
For problem above, devise a kind of using the trapped well for collecting the live rainwater automatic water supplement of storage, improve
The security and convenience of factory's seal water system, reduce cost.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
