Abstract
The utility model relates to a device that measures the strength and distortion properties of sediments on the surface layer of the deep sea, consists of a digging device and a clam-type digging device body with a shovel on the digging device, and is characterized in that the shovel of the digging device is positioned at least with a resistance sensor. Firstly, the resistance parameter of the solid mass of the sediments on the surface layer of the deep sea is measured so as to obtain the strength and distortion property parameters of the sediments by using the obtained resistance parameter and existing analysis and calculation methods. Namely during the sampling process in the deep sea, the shovel of the digging device is kept at 2 cm/s closing speed for a constant speed sampling. The collected resistance data an be analyzed through the existing static probing data processing system, and parameters, such as the intensity, compressibility, degree of density , consistency, bearing capacity and so on can be obtained. Obviously, the utility model has the advantages of a simple structure and a convenient operation, and realizes in using the obtained resistance parameter to originally and indirectly detect the mechanic property parameters of the sediments on the surface layer in the deep sea.
Description
Technical field
The utility model relates to the intensity and the deformation properties measurement mechanism 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 purpose of this utility model is to overcome the deficiency of prior art, provides a kind of energy the easy intensity of deep sea surface layer deposit sediment and the device of deformation properties, the i.e. measurement mechanism of the intensity of detecting deep surface deposit and deformation properties of obtaining.
The utility model makes full use of existing 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 drag parameter data and the existing analytical calculation disposal route obtained, just computable analysis goes out the parameters such as intensity, compressibility, packing, consistency state and bearing capacity of surface deposit.
Therefore basic technical scheme of the present utility model 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 by being installed in the resistance sensor on the freshwater mussel formula mud bucket perching knife and connecting a data acquisition processing device through cable, realized that original position detects the parameters such as compressibility, packing, consistency state and bearing capacity of sediment strength and sign deformation properties indirectly.
Obviously the utility model is simple in structure, easy to operate, is convenient to utilize the drag parameter of obtaining, and has realized that original position detects the parameters such as compressibility, packing, consistency state and bearing capacity of sediment strength and sign deformation properties indirectly.
