The hydrosphere (from Greek ὕδωρ hydōr, "water" and σφαῖρα sphaira, "sphere") is the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite. Although Earth's hydrosphere has been around for longer than 4 billion years, it continues to change in size. This is caused by seafloor spreading and continental drift, which rearranges the land and ocean.
A device for measuring geological fractures in the hydrosphere
The application relates to the technical field of water conservancy and environmental geology, and particularly discloses a measuring device for cracks in water conservancy and environmental geology, which comprises a support, a plurality of sliding blocks connected to the support in a sliding mode, an extender arranged on the sliding blocks, an installation plate fixedly connected to the extensible end of the extender, and a flexible plug rod assembly arranged on the lower side of the installation plate and capable of being inserted into cracks in the water conservancy and environmental geology layer. The measuring device for cracks in water conservancy and environmental geology provided by the application injects silica gel solution into the cracks, forms crack filling models after the silica gel solution is solidified, takes out the crack filling models from the cracks, measures the sizes of the crack filling models, and thus realizes the measurement of the cracks, so that the crack size measurement is more intuitive and accurate.
