Abstract
Main body of clam type dredge hopper of the disclosed detecting device includes arm of dredge hopper, and perching knife. Characters are that a resistance sensor is fixed on the perching knife of arm of dredge hopper. The method for measuring resistance parameter of earth body of sediments on surface in deep sea includes steps: in sampling procedure in seabed, closing speed of the perching knife keeps sampling at uniform speed 2cm/s; using current process system of static probing data can analyze resistance data so as to obtain parameters including intensity, compressibility, compaction degree, and thickness state of sediments, and bearing capacity etc. features are: simple structure, easy of operation.
Description
Technical field
The present invention relates to the mechanical property in situ detector of deep sea surface layer deposit sediment.
Background technology
Along with the development and use of the deep-sea energy, require more and more higher for submarine soil engineering properties Detection Techniques.At present commonly used in the world have method and relevant devices such as deep-sea drilling, seabed static sounding, the sampling of top layer mud bucket, the sampling of gravity core pipe and engineering geophysics.Deep-sea drilling is still blank basically at home, and seabed, deep-sea static sounding is from external introduction, but these two kinds of method complicated operations, apparatus expensive.Again because engineering geophysics can only be analyzed the character of submarine soil qualitatively, and mud bucket is got up is the disturbance sample, be used for analyzing the type of soil more, the gravity core pipe can be fetched sample the laboratory and carry out the physico-mechanical properties test, but disturbance through sampling and handling process, make sample " distortion ", can not accurately reflect the physico-mechanical properties of the original position soil body.Therefore in actual reconnoitring mostly usefulness be the mud bucket sampling, in conjunction with the method for engineering geophysics deep-sea soil body physico-mechanical properties is carried out qualitative analysis again, obviously still inconvenience of actual measurement.Again, present achievement in research can have been utilized the drag parameter of the soil body easily, analysis meter is calculated the parameter or the indexs such as intensity, compressibility and packing, consistency state and bearing capacity of surface deposit, obviously measures the drag parameter of the soil body of original position easily, is very necessary.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of mechanical property in situ detector of easy detecting deep surface deposit is provided.
The present invention makes full use of the mud bucket sampling equipment, as long as resistance sensor of fixed installation on the perching knife of existing freshwater mussel formula mud bucket, and in sampling process, measure the drag parameter of the soil body simultaneously, facilitate the use the parameters such as intensity, compressibility, packing, consistency state and bearing capacity that the drag parameter data obtained and the computational analysis of existing analytical calculation disposal route go out surface deposit.
Therefore basic technical scheme of the present invention is resistance sensor of fixed installation on the perching knife of freshwater mussel formula mud bucket, it is a kind of physico-mechanical properties in-situ detector of deep sea surface layer deposit sediment, include bucket arm and the perching knife on it in interior freshwater mussel formula mud bucket main body, it is characterized in that being that it also is included in resistance sensor of measuring the drag parameter of the soil body of fixed installation on the perching knife of bucket arm, and connect a data acquisition processing device through cable.Specifically detect parameters such as sediment strength, compressibility, packing, consistency state and bearing capacity indirectly by the resistance sensor in-situ that is installed on the freshwater mussel formula mud bucket perching knife.
Obviously the present invention is simple in structure, easy to operate, has realized utilizing the drag parameter original position of obtaining to detect the parameter of the mechanical property of table feature deep sea surface layer deposit sediments such as sediment strength, compressibility, packing, consistency state and bearing capacity indirectly.
