Quick installing and embedding device of concrete dam osmometer

Abstract

The invention provides a quick installing and embedding device of a concrete dam osmometer. The quick installing and embedding device comprises a galvanized steel pipe, wherein holes are uniformly formed in the surface of the galvanized steel pipe; a bottom cover is arranged on one end of the galvanized steel pipe, and one surface of the bottom cover is embedded in the galvanized steel pipe and istightly connected with the galvanized steel pipe; geotechnical cloth is arranged on the inner wall of the galvanized steel pipe, and the galvanized steel pipe is internally filled with dense medium-coarse sand; an observation osmometer is embedded in the dense medium-coarse sand, an observation cable is arranged on one end of the observation osmometer, and one end of the observation cable is exposed outside the galvanized steel pipe. According to the quick installing and embedding device disclosed by the invention, quick installing and embedding of the dam osmometer can be realized, the interference of installing and embedding construction of the dam osmometer to dam construction, particularly the interference to dam roller compacted concrete construction, can be avoided, the effective utilization time of a compacting machine is increased, and unnecessary idling of labor force is avoided; meanwhile, the installing and embedding efficiency of the osmometer is increased, and the safetyrisk brought by cross operation is reduced.

Description

technical field [0001] The invention relates to a quick installation and embedding device for a concrete dam piezometer, which belongs to the technical field of dam seepage pressure monitoring. Background technique [0002] Osmotic pressure monitoring is one of the necessary monitoring contents for dam working status identification. In recent years, many RCC dams have been developed and constructed in my country. Therefore, it is of great significance to quickly install buried piezometers and reduce interference with other construction processes. [0003] In order to avoid damage to the piezometer due to rolling construction, the original installation method requires digging, backfilling sand, and landfilling to install and bury the piezometer after the rolling has exceeded the installation and embedding elevation by about 30cm. The excavation of concrete requires a certain amount of manpower and material resources, and at the same time brings interference to the subsequent ...
