Description
Technical Field
The invention relates to the technical field of building anti-floating design, in particular to an anti-floating system capable of automatically overflowing, preventing blocking and draining and adjusting water quantity, a control method and a building.
Background
For river-facing buildings, because of higher groundwater level, the buildings usually need to be subjected to anti-floating design, and common anti-floating measures are mainly divided into two types, namely a passive anti-floating method for directly increasing the anti-floating capability of the building, such as anti-floating piles, anti-floating anchors and the like, which are most mature and most applied. Another is an active anti-floating method for reducing the buoyancy of the building, such as relief wells, drainage galleries, etc. Compared with a passive anti-floating method mainly comprising 'anti', an active anti-floating method mainly comprising 'row' can reduce or cancel the use of anti-floating piles and anti-floating anchors, reduce the thickness of side walls and bottom plates, save the construction period and have remarkable economic benefits.
For river facing buildings, coastal buildings are often affected by flood in flood season, and the underground water level of the river facing buildings is affected by flood and has the characteristic of greatly rising in a short period. Different from other buildings, the water level of the river-facing building is obviously influenced by the water level of river water, and the anti-floating building has the characteristic of obvious flood control and flood control. In the flood season, the river water level is greatly raised and is far higher than the normal water level, and for the conventional passive anti-floating design, the ground surface elevation is often adopted as the anti-floating water level, and the river-facing building in the flood season is at risk of anti-floating failure. For a common river-facing building, if the passive anti-floating design is carried out by adopting the water level of 50 years to 100 years to flood, the cost of the anti-floating pile or the anti-floating anchor and other measures is quite high, and the anti-floating measures cannot play a role in most of the time due to the very short action time of the flood, which is obviously quite uneconomical.
On the other hand, with current active anti-floating methods, the anti-floating water level is usually lowered directly below the basement floor, and this approach itself has a number of problems. If the groundwater level is lowered below the basement floor, there may be an excessive amount of water to be discharged even under the normal water level condition, and the excessive amount of water to be discharged may cause a series of problems such as sedimentation of the surrounding ground, overload of the drainage system, clogging of the drainage members, etc. At present, for the current active anti-floating method, the person skilled in the art can think that the water discharge amount flowing into the basement is controlled through the flow limiting valve, but the design scheme is easy to cause valve pipeline siltation, and once the underground water reaches the flood level, the flow limiting valve cannot be automatically opened up once power is cut off; in addition, those skilled in the art can also think of arranging the immersible pump in the water collecting tank of the building peripheral underground space, pumping groundwater to the water collecting well of the building basement through the water pump in a controllable flow, but this design scheme easily produces water pump impeller and twines or pump chamber jam by the foreign matter, especially once the outage appears the building anti-floating ability to lose efficacy or stay to the groundwater flow of water collecting well uncontrollable, because the municipal outage appears comparatively easily during the flood emergence, need rely on the inside emergency generator of building, but building anti-floating ability only can rely on the reliability of emergency generator and the immersible pump of water collecting tank, so still increased emergency generator's power supply burden.
