Abstract
The utility model discloses a monitor for pressure on original bores on earth on sea bottom, which has a length rod and a corresponding data collecting device comprising sleeves, a wimble tip resistance sensor on the front end part, a side rub resistance sensor, and hole hydraulic pressure sensors, which is characterized in that: the utility model comprises a plurality of hole hydraulic pressure sensors arranged on the joint, connected with the sleeves on two ends by the joint, and arranged on the long length rod, and a resistivity sensor is arranged on the joint. The utility model constructed thereout not only can monitor the hole pressure change in the soil body with different depth under wave action, but also can monitor the influence depth of the waves with different size, in order to analyze the stability of the soil body. At the same time, the utility model uses the resistivity sensor to test the resistivity of the soil body with different depth, in order to analyze the corrosion degree of the soil to the seabed pipelines and other engineering arrangements, providing scientific basis for the determining of the imbedment depth.
Description
Technical field
The utility model relates to the measurement mechanism of the physico-mechanical properties of the water-bed soil body, and specifically monitoring device is pressed in submarine soil original position hole.
Background technology
The wave period load action produce excess pore water pressure (being called for short the hole presses) in the soil body, but accumulation hole pressure is covered with efficacy above on the soil body, and unstability will take place the soil body, will produce the geologic hazard phenomenon, and marine engineering normal construction and operation are worked the mischief.Existing static sounding and pore pressure gauge equipment, monitoring is pressed in the hole that is widely used in marine soil property classification, layering and dam body, but only limit to the hole, top layer for seafloor soil and press observation, and can not layering observe, therefore also can't detect the degree of depth that influences of different big rips; In addition, also lack the mensuration of on-the-spot soil body resistance parameter, this parameter is to determine an important indicator of soil corrosivity, and is closely related with the mission life of seabed engineering structures (as subsea pipeline).
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of submarine soil original position hole of monitoring the wave excess pore water pressure that the different depth place produces in the soil body to press monitoring device.
Another purpose of the present utility model is when monitoring soil body endoporus is pressed, can also monitor the degree of depth that influences of the big or small wave of difference, and the resistivity of testing the different depth soil body simultaneously is to determine the corrosivity of soil to pipeline, structure base.
On the basis of prior art, this device includes measuring staff and the corresponding automated data acquisition device that the pore water pressure sensor of static point resistance sensor, side friction sensor and the postpone thereof of sleeve and leading section is formed, and it is characterized in that it also comprises with the alternate a plurality of pore water pressure sensors that are laid on the long measuring staff of joint; On above-mentioned corresponding joint, also laid soil body resistivity sensor, so that the resistivity of the while and the in-site measurement soil body.

Embodiment
Measuring staff and corresponding data acquisition device that the pore water pressure sensor of the utility model after by static point resistance sensor 1, side friction sensor 2 and the position thereof of sleeve 6 and leading section formed, it is characterized in that it also comprises is arranged on the joint 5, and be laid in a plurality of pore water pressure sensors 3 on the long measuring staff with joint 5 coupling sleeves 6, these are mainly with the pressure transducer 3 of the alternate layout of length sleeve, not only can press by the layering measured hole, also can monitor the degree of depth that influences of the big or small wave of difference.As another embodiment,, a resistivity sensor 4 also can be installed, on joint 5 so that soil body resistance parameter also can be measured simultaneously in the scene except a pore water pressure sensor 3 is installed; Consider drawing of multiway cable, be provided with the end connector 7 in a tape cable hole 8 on the measuring staff top, cable aperture 8 is outlets of multiple signals cable.Above-mentioned pore water pressure sensor can adopt the piezoresistive transducer of band stainless steel isolation diaphragm etc., and guaranteeing that technically drift is little, precision is high and carry out quick kinetic measurement.
The utility model of constructing thus can not only be monitored under the wave action different depth soil body endoporus and be pressed, and can also monitor the degree of depth that influences of different big rips, with and soil body resistivity.
