The invention relates to land reclamation and can be used for research and operation of land reclamation systems.

The purpose of the invention is to increase the efficiency through pipelines 12 and II and elastic 10 to the surface of the water in the tank 6. Water from it under the action of overpressure flows into the piezotivnost of the monitoring service with meter 9, and tank 6 floats, following

water level in chamber 1.

Similarly, the device operates at lowering the water level and the formation of a vacuum in the cavity of the drain 3. In this case, water flows from the piezo exclusion topping up the piezometer before measuring.

The drawing shows the device section.

The device consists of a sealed settling chamber 1 connected to the tank 6 about 10 meters. The adapter 2 is equipped with a drain 3. The tank 6 is filled with water at the moment

Filter 4 coincides along the generator of the drain 3, installation and installation of the device on the protective silting chamber and about 2/3 of its volume. In petition hydraulics flow in the drain. In the process of exploiting part of the water from it

The stannic chamber 1 is installed with the air, will be consumed for evaporation, moving along the guides, coaxing, etc., so it should be periodically carried out in the form of a perforated cis-to-do watering (1-2 times

connected with an elastic pipe 8 to a gauge at known elevations by means of a piezometer 9 and 10 with a rigid duct reading (bottom drain) OO and the top with water 11. To the latter, the depth of filling is determined in its oc-piezometer

A pipe 12 is connected, which is connected to the upper point of the drain cavity 3. The locking devices (valves, etc.) 13 and 14 serve to change the mode of operation of the device.

The device works as follows.

In the period between measurements, the valve 13 is open and the valve 14 is closed. When the water rises in the drain 3, it flows over the adapter 2 into the chamber 1 and through the perforations into the cylinder 5, as a result

Claims (3)

Claim 1. Device for determining the filling of the drain, including a liquid piezometer with fixing the reference plane 2Q at the bottom of the drain, characterized in that, in order to increase the work efficiency the tank 6, following the water level of the surveillance service, the device is equipped in chamber 1, it floats, and the water level in the non-settling chamber is located in and in chamber 1, they coincide, thanks to the pop-up, with the ability to move around the safety seat 7, which ejects the force to the leveling tank with the float, while equal to the weight of the elastic pipelines 8 and 1035 of the settling chamber communicated with the tank 6. When the tank is raised, the water is idle and the tank is hydraulically connected to it flows through the elastic pipe 8 into the piezometer 9. In the latter, a water level is formed equal to the water level in the drain. In the case of positive excess air pressure in the cavity of the drain 3 with the valve 14 open and 13 closed, it the lower part with a piezometer, and in the upper part - with the atmosphere and drains. 2. A device according to claim 1, characterized in that the settling chamber 40 is communicated with the drain through an adapter equipped with a filter having the form of an internal forming drain. It is transferred through pipelines 12 and II and elastic 10 to the surface of the water in the tank 6. Water from it under the action of overpressure flows into the piezometer 9, and the tank 6 floats up, following water level in chamber 1. Similarly, the device operates when the water level is lowered and vacuum is formed in the drain cavity. 3. In this case, water flows from the piezometer to the tank 6. The tank 6 is filled with water at the moment The counting bones (the bottom of the drain) of the RO and the top of the piezometer determine the depth of filling. drains and the amount of excess pressure by the formulas Nvadi V 1 -V2-hi; Bf6 V 1 V 2i-h2. with Claim 1. Device for determining the filling of the drain, including a liquid piezometer with fixing the reference plane 2Q at the bottom of the drain, characterized in that, in order to increase the work efficiency the lower part with a piezometer, and in the upper part - with the atmosphere and drains. 2. A device according to claim 1, characterized in that the settling chamber 40 is communicated with the drain through an adapter equipped with a filter having the form of an internal forming drain.
