POOL FOR TESTING WATERPROOFING GEOSYNTHETIC MATERIALS (GSM) IN NATURAL CONDITIONS Russian patent published in 2023 - IPC E02D31/10 

FIELD: hydraulic engineering.

SUBSTANCE: invention relates to the field of hydraulic engineering and can be used for a comprehensive field study of the efficiency of fuel and lubricants as part of elements of real structures of impervious elements of PFE of ground hydraulic structures of hydraulic structures in conditions as close as possible to the actual operating conditions of a particular hydraulic structure. The pool for testing waterproofing geosynthetic materials fuels and lubricants in natural conditions contains a pool 1 having a bottom and sides and equipped with a monitoring system consisting of a piezometer 15 to control the level of groundwater in the natural base of the pool 1 and embedded plastic pipes 5 for measuring parameters using humidity sensors and temperature. The monitoring system includes a permafrost meter installed in the soil 4, laid on the sides of the pool 1 over the drainage layer 12, ion-selective electrodes 17 and a salt meter 16 installed in the piezometer 15, a fiber optic cable 3 laid over reinforced waterproofing 2, and a flow meter 9 installed on drainage pipeline 8. The bottom and sides of the pool 1 are made of reinforced concrete with reinforced waterproofing 2, while the laying of the sides is in the range of 1:6 - 1:4, and the depth of the pool 1 is at least 5 meters. A pipeline 13 for supplying water or a test liquid and a pipeline 7 for draining it are connected to the bottom of the pool 1, a drainage layer 12 is laid on top of the reinforced waterproofing 2 of the bottom with a drainage pit 11 located in it, to which the drainage pipeline 8 is connected. The drainage system is located under the reinforced concrete slab the bottom of the pool 1 and is made in the form of reservoir or systematic drainage with systematic drains 14, which are located at a depth of at least 0.5-0.8 m.

EFFECT: ensuring the study of the efficiency and reliability of the operation of fuels and lubricants in the structures of the PFE of soil hydraulic structures and providing the possibility of conducting research on the technical characteristics of fuel and lubricant samples withdrawn after long-term operation in the structure of the PFE of soil hydraulic structures.
