Description

Strong permeable stratum anti-drainage combined basement anti-floating structure and control method

Technical Field

The invention belongs to the technical field of basement anti-floating, and particularly relates to an anti-floating structure of a basement with combination of strong permeable stratum resistance and drainage and a control method.

Background

At present: along with the development of city construction, urban land is reduced gradually, and the development and the utilization of underground space are constantly improved, and for shallow basements or deeper basements with the ground as a bottom building group, conventional anti-floating schemes such as facility anti-floating piles are needed when anti-floating is insufficient, and the scheme of removing underground water by using foundation pits can be adopted to solve the anti-floating problem of basements.

The anti-floating anchor rod is one of anti-floating measures of an underground structure of a building engineering, refers to a structural member arranged for resisting upward displacement of a building on the anti-floating anchor rod, is related to the height and the change condition of an underground water level, and is opposite to the stress direction of a compression-resistant pile; the anti-floating pile bears the pulling force for the anti-pulling pile body, the stress of the common anti-floating pile is also transferred from the pile top to the pile bottom, and the stress of the pile body is changed along with the change of the underground water level.

The anti-floating water level is the highest water level in the past year, the highest water level in the use period is predicted, but in recent years, extreme weather occurs, and the underground water level is higher than the designed anti-floating water level, so that a large amount of basements float upwards.

Through the above analysis, the problems and defects of the prior art are as follows: in recent years, the highest water level of the service life cannot be predicted due to the occurrence of extreme weather or the influence of the surrounding environment, the underground water level is higher than the designed anti-floating water level continuously, if the underground water level is designed according to the high water level, the anti-floating cost is greatly increased, and energy conservation and emission reduction are not utilized.

The invention uses the perennial water level as the anti-floating fortification water level, adopts the anti-floating anchor rod or the water resistant plate to resist, is higher than the water level, adopts the drainage solution, ensures that the water level is not higher than the fortification water level, and the time higher than the water level is very little, and has lower cost because of very little drainage time.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides an anti-floating structure of a basement with combination of drainage resistance of a strong permeable stratum and a control method.

The invention is realized in such a way that the basement anti-floating structure with the combination of the strong permeable stratum anti-drainage is provided with: the anti water board, anti water board below is provided with anti-floating anchor rod (only establish when water board is unsatisfied to set up), newly-built basement sets up the filter well in the sump pit periphery, the filter well is connected with the drain pipe, install total valve and manometer earlier on the drain pipe, install emergency valve on it, the special circumstances of being convenient for opens the drainage, upwards installation pressure transmitter and electric ball valve are again followed to the drain pipe, and pressure transmitter passes to the control box with pressure data through the cable, and the control box passes through the electric ball valve switch of cable control, and the drain pipe top is equipped with the exhaust hole.

Furthermore, the adoption of the water-resistant plate and the anti-floating anchor rod (which is arranged when only the water-resistant plate is not satisfied) resists the anti-floating force below the fortifying water level; through the drainage, prevent that groundwater from being higher than the water level of seting up defences.

Further, the basement sump outside sets up the filtration well, filters the well and adopts pervious concrete pouring.

Furthermore, a drain pipe is arranged in the basement sump and extends into the filter well.

Further, a main valve and a pressure gauge are arranged on the drain pipe extending out of the water collecting pit.

Further, establish emergency valve on the drain pipe, be convenient for when emergency the drainage and whether the inspection drain pipe is unobstructed.

Further, establish pressure transmitter and electronic ball valve on the drain pipe, pressure transmitter passes to the control box with the pressure value through the cable.

Further, the top of the gravity flow drain pipe extends to the anti-floating water prevention level.

Furthermore, the top of the drain pipe is provided with an exhaust hole.

The invention also aims to provide a control method of the basement anti-floating structure with the combination of the drainage resistance and the drainage resistance of the strong permeable stratum, wherein when the control method is used, a valve is opened all year round, a pressure gauge is checked, and the distance between the water level and the annual highest water level is known; the emergency valve is opened once every year, the blocking condition of the drain pipe is known, and in extreme weather, when the water level reaches the anti-floating defense water level, the electric ball valve automatically drains water, and the top automatically drains water as a safeguard measure.

By combining all the technical schemes, the invention has the advantages and positive effects that: according to the invention, the anti-floating water level and buoyancy anti-floating requirements of the basement are met by arranging the anti-water plate and the anti-floating anchor rod, and the underground water can be drained into the sump through the arrangement of the filter well and the drain pipe, so that the effect of controlling the underground water head is achieved; through the arrangement of the pervious concrete around the filter well, the effects of filtering the accumulated water in the basement and preventing the drain pipe from being blocked can be achieved; by arranging the emergency valve, drainage can be performed and the smoothness of the drainage pipe can be checked under special conditions; by arranging the pressure gauge, the pressure of underground water can be monitored; the pressure transmitter converts water pressure into a frequency signal and transmits the frequency signal to the control box, the control box identifies the frequency signal, and when the pressure value exceeds a designed value, the electric ball valve switch is opened to discharge underground water into the sump; the return pipe that flows automatically at drain pipe top is a little less than anti floating and prevents the water level of defending, and when the water level was close anti floating and prevents the water level of defending, the drainage that can flow automatically prevented the electric ball valve switch inefficacy and arouses the accident as the safety guarantee measure, and drain pipe top exhaust hole prevents the siphon effect. The device can get rid of groundwater when extreme weather, prevents to appear that groundwater level is higher than the condition of the anti water level that floats of design to the come-up problem of a large amount of basements when having solved extreme weather.
