Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

Example 1

Aiming at the rapid rise of water level caused by sudden rainstorm in a short time, the invention provides an anti-floating system for a basement, which is designed and conceived to change blockage into dredging and lead underground water from the interior to achieve the anti-floating effect. Referring to fig. 1, the anti-floating system includes at least one overflow unit 1. The overflow unit 1 comprises an overflow pipe 2, a water collecting well 3 and a water filtering device 4; the upper end of the overflow pipe 2 is provided with an overflow port, and the lower end is provided with a water inlet; the overflow pipe 2 vertically penetrates through the water collecting well 3, and the overflow pipe 2 is led out of the basement after penetrating through the bottom plate of the basement; the water collecting well 3 comprises a shell which is arranged around the overflow pipe 2 and surrounds to form an accommodating space; the upper end of the water collecting well 3 is provided with a water collecting gap for the water flowing out of the overflow gap to converge into the accommodating space; the water inlet is communicated with the water filtering device 4.

As an alternative embodiment, the overflow gap at the upper end of the overflow pipe 2 is set lower than the warning water level, for example, the elevation of the warning water level is-1 meter, and then the elevation of the overflow gap is-1.1 meter. Meanwhile, as the underground water is required to overflow from the pipe opening, the designed elevation of the overflow gap at the upper end of the overflow pipe 2 is lower than that of the top plate of the basement. According to the principle of the communicating vessel, the water level in the overflow pipe 2 is equal to the underground water level outside the underground chamber, and the water level is slightly lagged behind the underground water level outside the underground chamber due to the filtering device. When rainstorm causes the water level outside the basement to rise and endanger the water level warning line, because the gap on the upper end of the pipe opening is lower than the ground water level, the underground water can be ensured to overflow from the overflow pipe 2 in time and flow into the catchment well, thereby achieving the effect of leading water into the room and effectively relieving the oppression of the peripheral buoyancy of the basement to the building structure.

As an alternative embodiment, the top of the water collecting well 3 is lower than the bottom plate of the basement, and an indoor drainage ditch is arranged along the ground of the basement, and the indoor drainage ditch is communicated with the water collecting well 3. Like this, under the prerequisite of leaving the breach that catchments, the sump pit 3 wholly is located basement bottom plate below, needn't occupy indoor space, and the water in the indoor escape canal gathers into sump pit 3 simultaneously.

Referring to fig. 2, the anti-floating system of the present embodiment further includes a power device 5 and a water outlet pipe 6, one end of the water outlet pipe 6 is communicated with the water collecting well 3, and the other end is led out to the outside of the basement; the power device 5, such as a water suction pump, can drain accumulated water in the water collecting well out of the basement through the water outlet pipe 6.

In this embodiment, the bottom of water filtering device 4 and the basement outside intercommunication, the inside grit that is equipped with of water filtering device 4, groundwater pours into overflow pipe 2 through water filtering device 4.

In this embodiment, as a preferred implementation manner, the number of the overflow units 1 may be set to be a plurality, for example, when the area of the basement is large and the elevation of the building is low, the overflow units work simultaneously, which is beneficial to ensuring that the damage of the groundwater pressure to the basement building is relieved as much as possible.

The anti floating system that this embodiment provided, through set up the anti floating effect that the overflow unit strengthened the basement at the basement, especially under the condition of dealing with the big rainfall in short-term, can effectively protect the building structure of basement to avoid the destruction that groundwater caused.

Example 2

Referring to fig. 2, the embodiment provides a basement anti-floating system based on embodiment 1, where the anti-floating system includes a water level sensor 7 disposed inside the overflow pipe 2, and may measure the water level by using the principle of fluid statics, that is, measure the water level parameter inside the overflow pipe 2, such as the current water level elevation; the anti-floating system also comprises a central control device 8, and the central control device 8 can control the power device 5 according to the water level parameters transmitted back by the water level sensor 7. For example, when the water level rapidly rises due to the occurrence of a heavy rain, the central control device 8 stops the operation of the power device 5 due to the large instantaneous underground water pressure outside; and when the rain stop water level is restored to be within the warning water level line, the central control device 8 starts the power device 5 to work and begins to drain water to the underground chamber.

In this embodiment, the anti-floating system is provided with an alarm device 9; the central control device 8 detects that the water level parameter triggers a preset alarm condition, for example, the water level elevation exceeds a safety threshold of the water level, the central control device 8 starts the alarm device 9, and the alarm device 9 can trigger a loudspeaker, automatically send a short message to the outside, and the like.

On the basis of the embodiment 1, the embodiment can also obtain water level parameters through the central control device through the anti-floating system, and control automatic drainage and automatic alarm on the basis, so as to realize automatic treatment of overflow in the anti-floating process.

Example 3

The embodiment provides a basement anti-floating system on the basis of embodiment 2, and the anti-floating system comprises a conveying device which consists of a mechanical lifting module and a crawler conveying module. The central control device 8 obtains a water level prediction parameter and a safety height according to the water level parameter. For example, a rainstorm water level rising prediction model of the area where the basement is located is built according to local rainstorm historical data and geological structures, and when the rainstorm causes the water level in the overflow pipe 2 to rise, the central control device 8 substitutes the water level parameters obtained in real time and real-time weather forecast data into the prediction model so as to obtain water level prediction parameters, wherein the water level prediction parameters comprise the water depth of the basement possibly caused by the overflow capacity of the overflow pipe and the like. The central control device 8 selects a preset safety height according to the predicted water level parameter, controls the conveying device to move and lift the specific indoor articles to the safety height, finishes indoor drainage after rainstorm, and then replaces the articles by the conveying device.

The anti system of floating of this embodiment can also realize prejudging the water level in the basement through well accuse device to article in the basement carry out timely safety processing based on this, ensure that the property of storage avoids the water logging.
