Abstract
An original-position detecting device used for obtaining physical property parameter of deposit on surface of sea-bottom is prepared as fixing a water content probe on metal cylinder vertically or axially and connecting said probe to data collection and treatment unit by armoured cable as well as making probe head be extended out from said cylinder, considering to measure natural density of surface soil body simultaneously than also fixing a density probe being connected to data collection and treatment unit through armoured cable on said metal cylinder.
Description
Technical field
The present invention relates to the device of the sedimental physical-property parameter of a kind of in-situ test submarine surface soil body, specifically the in-situ detector of the physical-property parameter of deposit on marine-bottom surface.
Background technology
The physical-property parameter of deposit on marine-bottom surface, as sediment natural moisture content and natural density, the engineering structure of submarine surface of design and construction directly be seated to(for) submarine pipeline, cable etc. are indispensable important parameters.The test of these physical-property parameters is that the chamber test draws by experiment at present, yet sediment is carried to the laboratory from being sampled to, and very easily produces the dehydration disturbance, causes indoor test result and actual result deviation to occur.Obviously the measuring error of having only in-situ test just can avoid this disturbance to bring just can reflect the on-the-spot sedimental water status and the packing in somewhere, more accurately for engineering design provides scientific basis.
Summary of the invention
The in-situ detector that the purpose of this invention is to provide a kind of physical-property parameter of deposit on marine-bottom surface is to remedy the deficiency of prior art.
The data acquisition processing device that the present invention utilizes existing water cut probe and density to pop one's head in and match fast is applied to measure the physical-property parameter of the submarine surface soil body with it, as sedimental natural moisture content and natural density.
The present invention includes vertically or be axially fixed at a water cut probe of metal cylinder, and is connected with data acquisition processing device, and to stretch out metal cylinder external in this water cut detection termination of popping one's head in via an armouring cable at top.
Consider the natural density of measuring the submarine surface soil body simultaneously, in above-mentioned metal cylinder, fix a density probe that is connected with data acquisition processing device through the armouring cable, and to stretch out metal cylinder external in the detection termination of this density probe.
Obviously, of the present invention simple and reasonable, easy to operate, can realize the in-situ investigation of water-bed surface deposit, be that the scene accurately measures sedimental original position natural moisture content and these physical-property parameters of natural density simultaneously, for engineering design provides more reliable scientific basis.
