In order to explain the siphon device in detail, the present embodiment also provides an operation process of the siphon device.
When surface water exists at the bottom of a water collecting well or an elevator shaft of a bearing platform or a formal project, water flows penetrate into a siphon perforated pipe section through a small hole of a section body of the siphon perforated pipe section and flows to a siphon perforated solid pipe section through a slope, and finally flows to a liquid level control valve, because two magnetic plates block the water, when the water amount in the liquid level control valve is small, the magnetic plates are in a mutually-attracted closed state, once the water amount is accumulated and rises to a certain height, the two magnetic plates can be separated by the gravity of the water, the water flows are flushed into the water collecting well to cause a siphon phenomenon, the air pressure in the siphon perforated pipe section close to the bottom of the bearing platform is reduced, and the water flow in the siphon perforated pipe section enters the water collecting well along a siphon solid pipe to realize the discharge of the surface water of a foundation pit; when the water quantity is gradually reduced, the water pressure borne by the magnetic plate is also reduced, the magnetic plate resets again due to the magnetic force and the elastic force of the spring, the position of the water outlet of the liquid level control valve is closed, the water is continuously stored until the water flow is high enough, the magnetic plate is flushed away, and the next siphon drainage work is carried out.
Particularly, in the foundation construction stage of the construction engineering in the downstream of the mountain land topography just in the rainy period, the surface water of the foundation pit is rich, at the moment, the water flow penetrates through the gravel filtering layer, passes through the geotextile 16 and then passes through the holes of the siphon perforated pipe section to reach the inside of the pipe, when the water flow in the pipe is more and more, the water flow finally converges to the siphon solid pipe section and flows to the surface water collecting pithead through the siphon solid pipe section, then flows downwards to the liquid level control gate, the water quantity of the liquid level control gate in the solid pipe section is gradually increased, when the set water quantity is reached, the 'control valve' is opened immediately, the water flow is completely injected into the surface water collecting pit, a part of negative pressure cavity is formed in the siphon solid pipe section, the negative pressure cavity sucks all surface water near the siphon perforated pipe section to form siphon drainage effect, therefore, the water level in the foundation pit of the formal engineering is ensured to be reduced, and the subsequent construction processes of water prevention and the like are not influenced.
When the water quantity in the surface water collecting pit reaches a set water pumping level, the staff can pump and drain the water.
To sum up, this be used for foundation ditch earth's surface water to fall and arrange gravity type siphon system device can be when one has rainfall, foundation ditch internal ponding, carry out timely drainage to foundation ditch internal ponding, and do not have traditional sewage pump to draw water and receive the influence of water level height and can not arrange the internal ponding of pit completely, still need combine the defect of artifical drainage, guarantee the foundation ditch through being used for foundation ditch earth's surface water to fall to arrange gravity type siphon system device and do not have ponding constantly, this be used for foundation ditch earth's surface water to fall to arrange gravity type siphon system device and compare with traditional drainage technique, the technical aspect: the device can ensure that the foundation pit always keeps automatic water drainage and no accumulated water is left in the foundation pit; in the aspect of economy: the manufacturing and using cost is low, and as sewage pumps are not used for repeated pumping and drainage and manual auxiliary drainage, the financial and manpower input is greatly reduced; social benefit aspect: because the device replaces an electric sewage pump by a siphon principle, a large amount of electric energy can be saved, and the device has a promoting effect on green and environment-friendly construction.
