Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of safety monitoring of water conservancy and hydropower, in particular to a combined installation protection device for inclinometer and osmotic pressure gauge and a use method thereof. BACKGROUND

[0002] Internal displacement and seepage monitoring of dam body and dam foundation are important monitoring contents in safety monitoring of earth-rockfill dam. According to the requirements of the Design Specification for Safety Monitoring of Water Conservancy and Hydropower Projects (SL725-2016), the layered vertical internal displacement of earth-rockfill dam can be monitored by using inclinometer, and the osmotic pressure of dam body and dam foundation should be monitored by using osmotic pressure gauge.

[0003] The internal displacement monitoring is usually performed by drilling a hole to a designed depth and then burying an inclinometer tube, and fixing and installing an inclinometer sensor in a vertical slot inside the inclinometer tube at a specified depth. The osmotic pressure monitoring is usually performed by drilling an inclinometer hole to a designed depth and then burying a pressure tube, and installing an osmotic pressure gauge sensor at the bottom of the pressure tube. If the longitudinal section of the internal displacement monitoring of dam body and the seepage monitoring of dam foundation are consistent, the two types of sensors can be buried in the same hole in theory to save drilling cost. However, in actual construction, it is difficult to bury the two types of sensors in the same hole due to the inconsistent installation environment and requirements of the inclinometer and the osmotic pressure gauge, the inconsistent size and interface structure of the inclinometer tube and the pressure tube, and other reasons, which greatly increases the construction cost.

[0004] In view of the above problems, a device for fixing inclinometer and osmotic pressure gauge to be buried in the same hole is disclosed in the Chinese Utility Model Patent with the authorization announcement No. CN218179903U, which comprises an inclinometer tube section and a pressure tube section; the inclinometer tube section and the pressure tube section are connected through a connecting device; the inclinometer tube section comprises a plurality of inclinometer tubes; the two ends of each inclinometer tube are provided with a connecting device; the plurality of inclinometer tubes are connected by the connecting devices; the inclinometer tube and the pressure tube section are connected by the connecting device; the connecting device is sleeved on the connection of the plurality of inclinometer tubes and on the connection of the inclinometer tube and the pressure tube section; the inner diameters of the inclinometer tube and the pressure tube section are equal; a tube bottom device is installed at the bottom end of the connecting device; a tube bottom device is installed at the bottom end of the pressure tube section; the tube bottom device comprises a tube bottom connector and an inverted cone cap; the outer diameter of the tube bottom connector is consistent with the inner diameter of the inclinometer tube port, and the bottom of the tube bottom connector is closed by the inverted cone cap. The device has the advantage that the fixed inclinometer and osmotic pressure gauge sensors located in the same monitoring longitudinal section can be buried in the same monitoring hole.

[0005] However, the device for fixing inclinometer and osmotic pressure gauge to be buried in the same hole ignores the protection of the exposed cable of the instrument in the use process, and the instrument cable is easily damaged in the installation process of the inclinometer hole of the high slope, which affects the normal monitoring, prolongs the construction period and increases the cost. Moreover, the device can only be used with the fixed inclinometer, the cost is too high, and the overall construction cost is high. SUMMARY
