It rises.In order to make full use of space, skyscraper often has subterranean layer, and has and use water spot.When the buried depth foot of outdoor drainage pipe network
When enough, the problem arises for corresponding basement drain.Outdoor drainage pipe network tube bottom absolute altitude is lower than indoor water appliance mark according to reason
Height, it is in line best, but since elevation of levelled ground is significantly larger than the absolute altitude of indoor water spot, once outer net blocking or rainfall
It results in water level in outer net to be increased to more than water spot absolute altitude, will lead to the recharge with water spot, indoor sewage is caused to spread unchecked.?
In this case, if using sump make-up water pump control mode, just not saying sewage pump be on the point of numerous unlatching generate noise, vibration and
Power consumption, sewage quality are also not suitable for water pump through normally open.By taking Qingdao City as an example, do not allow the interior lower than outdoor inspection shaft absolute altitude
Tube net outside is directly accessed with water spot drainpipe.However, developer is not it is also known that user likes oneself sewage is discharged by dredge pump,
The still existing of the mode of being directly accessed is taken, but has also buried hidden danger.
The invention patent designs a kind of basement combined drainage system, in the possible situation of no recharge, lower than outdoor
The high sewage with water spot of inspection shaft top mark is to tube net outside normal discharge, and only in the case of recharge occurs in outdoor, sewage is
The sump of outdoor setting can be flowed into, and when the Well Water Level that catchments reach a certain height, outdoor sewage pump just starts to open
It is dynamic, complete a pumping cycle.After tube net outside water level decreasing, then normal indoor water spot is automatically replied to tube net outside
Draining.
A kind of basement combined drainage system of the invention patent, has considered proper drainage condition and dump item as a whole
Part, usually water pump not will use, and lower placement is safeguarded after use, can play the role of protecting water pump, caused by avoiding sewage
Smelly pond and sundries have good practical value and Popularizing of A.
Summary of the invention:
It is an object of the invention to overcome disadvantage of the existing technology, seeks design and a kind of basement comprehensive draining is provided
System.
To achieve the goals above, basement combined drainage system (post-processing) of the present invention
Compared with prior art, the present invention solving indoor water spot absolute altitude higher than tube net outside system absolute altitude and lower than room
The high drainage problem of outside ductwork well top mark can both avoid recharge from leading to indoor sewage crossing current problem well, can also be in room
Sewage self-flowing outlet under outside ductwork circulation condition.It is higher than tube net outside system absolute altitude with water spot absolute altitude indoors and is lower than outdoor
Under the high drainage situation of pipe network well top mark, pump and maintenance management are changed in the power consumption that the present invention overcomes simple by water pump operation, also gram
The hidden danger that outer net blocking occurs in direct outlet is taken.
The present invention cuts pipe in the state of the external sewage pipe water burst in downstream, it will overflow sewage catchments into sump
Well Water Level rises to certain altitude just and will start water pump reduction water level, is unlikely to wastewater level and continues to rise and cause recharge to out
Family pipe and indoor, water level decreasing to certain altitude then termination of pumping.For the present invention in addition to production cutting pipe according to field condition, other parts are equal
In-site installation can be chosen with market, system structure is simple, and sump and the linkage of outdoor sewage well, easy for assembly, maintenance is easy, fortune
Row is highly-safe.
