Geomembrane is born hydraulic pressure and is adapted to dam body as a kind of with high molecular polymer, larger tensile strength and elongation percentage
Deformation, because its impermeability is widely used in hydraulic engineering, to separate the leakage passage of flow.China is in early days by geomembrane
For bottom storehouse or the vertical plastic spreading seepage control project at canal bottom, in recent years in hydraulic engineerings such as Wall in Plain Reservoir using wide；In Plain
It is a kind of effective technology using geomembrane anti-seepage in the engineerings such as reservoir, rock, rivers and canals, cofferdam.
Under normal conditions, if laying multiple monitoring nodes under geomembrane to obtain the status data of bottom storehouse or canal bottom,
Generally require to be controlled one by one, control system caused to complicate, according to network structure, then need using bus structures into
Row data transmission, once some monitoring node damages cisco unity malfunction, then gathered data just will appear blank, there is monitoring
The monitoring to bottom storehouse or the integrity of canal bottom and geomembrane still cannot be completely secured in the isolated island of node, will be each according to rope
It is a feasible mode that a monitoring node chain, which gets up to form monitoring node array, but in monitoring node array, different location
Monitoring node structure has difference, and some often only needs the monitoring node with side to be linked with rope at the edge of array,
Some then needs the node with front, rear, left and right, surrounding to be linked then at the center of array, and therefore, it is necessary to using a variety of
The monitoring node of structure is for selection.
Currently, in urban construction and part hydraulic engineering, ground that is poor for geological conditions, lacking ideal impermeable stratum
Area carries out antiseepage using geomembrane becomes preferred option more.The reason is that geomembrane belongs to flexible material, underwater is deformed
Adaptability it is very strong, not by external force pierce through, tearing in the case of, aging speed disclosure satisfy that most hydraulic engineerings
Economic life demand, especially suitable for more earthquake areas and karst area as bottom storehouse anti-seepage scheme.
In practice, the integrality of geomembrane can face the tests such as underwater deformation, and underwater deformation is general
It is that ground is subside under film to have two class situations, one kind, causes geotechnological membrane part hanging, and tension, the shearing strength of membrane body are relatively low, separately
One kind is that ground protuberance and gas expansion lead to geomembrane local pressure, displacement etc. under film.In short, underwater bottom storehouse geomembrane
Once geological environment, water and soil biology, liner external force and the effects that flatulence under be damaged, " cracking position is difficult to determine " this
Significant deficiency displays immediately.It is passed through after geomembrane due to infiltration and is spread in the soil body rapidly, even if pre-buried monitoring instrument
Damage location can not be determined in a small range.The repairing opportunity that this drawback makes membrane body cracking initial stage of short duration loses, and makes geotechnique
Film is torn and seepage failure drastically extends, and seriously threatens the safety of hydraulic engineering.
In short, geomembrane once generates destruction, library water leakage can be aggravated, cause a large amount of water losses, and influence reservoir
Normal operation jeopardizes engineering safety.Therefore, it is necessary to take effective monitoring technology to geomembrane operation.
