Abstract

The invention discloses a method for monitoring concentration of suspended substances in construction sea area by using a sampling device, and aims at solving the deficiency that when the concentration of suspended substances in a construction sea area is monitored and sampled, the sampling operation on sea water at a certain depth position cannot be achieved. When dredging work is performed in the construction sea area, sea water is periodically sampled to monitor the concentration of the suspended substances; firstly, the length of a positioning column is adjusted according to the depth of the sea water needing to be monitored, and then the positioning column is inserted into the water bottom for fixing; the upper end of a sampling pipe is exposed out of a water surface; mechanical tongsapplied to construction work touch a push plate or a connection rod during a construction process, or a water flow generated by the mechanical tongs during the construction process impacts the uppersurface of the push plate, to drive the connection rod to rotate clockwise; a puncture needle moves upwards to puncture a waterproof membrane; the sea water flows into a water inlet section, a water accumulation section and the sampling pipe from a hole on a water inlet side; after a period of time, the sampling pipe is pulled upwards, and if a user finds that the sampling pipe gets the sea water,sampling can be completed by directly pulling the whole sampling device out of the sea water.

Description

technical field [0001] The invention relates to a seawater monitoring and sampling method, more specifically, it relates to a method for monitoring the concentration of suspended matter in construction sea areas by using a sampling device. Background technique [0002] At present, during the operation in the construction sea area, it is necessary to regularly sample and detect the concentration of suspended solids in the seawater in the area. The traditional seawater sampling method is to directly throw the sampling bucket into the seawater, and pull the sampling bucket with a rope to sample the seawater. Sampling Lift the sampling bucket after the bucket is filled with seawater. This sampling method is easy to operate, but the water layer where the sampled seawater is located is uncertain. It may be at the water surface or in the water. Seawater sampling has relatively large limitations, and it is impossible to accurately monitor a certain depth in the seawater. Suspended ...
