Fig. 2 is the structural representation of the utility model water absorber;
Fig. 3 is the structural representation of the utility model water filling device.
Embodiment
As shown in Figure 1 to Figure 3, of the present utility modelly mainly comprise sighting tube 3 based on basis of dual porosity water pressure instrumentation settlement measuring device, the the first type vibration wire pore pressure gauge 1 being communicated with sighting tube by conduit 4 and the second type vibration wire pore pressure gauge 2, be coated on the protective sleeve 5 of conduit 4 peripheries, the first wire 61 being connected with the first type vibration wire pore pressure gauge 1, the second wire 62 being connected with the second type vibration wire pore pressure gauge, for covering the protective cover 7 of sighting tube 3 ends and accommodating respectively the first protection box 91 and the second protection box 92 of described the first wire 61 ends and the second wire 62 ends.
In the time of engineering construction, conduit is for can adopt nylon tube, and protection can adopt PE cover, and the first protection box and the second protection box can adopt stainless steel box.
Further; the utility model also comprises other devices; with composition measuring system, be for example placed in the observation liquid 12 in conduit and sighting tube, the sealing liquid 13 that floats on observation liquid liquid level, the frequency recorder for being electrically connected with the first wire or the second wire, described conduit periphery is coated with protective sleeve 5.
Implementation process of the present utility model is as follows: first connect respectively with two apertures of two sections of conduits and sighting tube bottom, to observe again liquid (for example air free water) inject sighting tube, treat that two sections of conduit other ends have liquid to flow out, the port of two sections of conduits is connected in observation liquid with the first type vibration wire pore pressure gauge, the second type vibration wire pore pressure gauge respectively, in case there is air to enter in conduit.Keep there is appropriate observation liquid in sighting tube; again the first type vibration wire pore pressure gauge is embedded in to the tested point place under embankment 8; catheter jacket is protected with protection tube; lay sand bed protection around, the wire of the second type vibration wire pore pressure gauge is adjourned non-construction area on ground, and sighting tube is placed in non-construction area; sighting tube bottom is protected with sand; fixedly make sighting tube vertical around, sighting tube opening part is applied mechanically protective cover, avoids evaporating and enters with rainy day rainwater.By the wire that the connects type vibration wire pore pressure gauge ground of also moving out, last two terminals should be positioned over respectively stainless steel box the inside, avoid geomantic omen Exposure to Sunlight.
Measuring process of the present utility model is as follows: survey crew frequency of utilization instrument is clamped the joint of the wire that is placed on stainless steel box the inside, and the frequency of reading is the frequency of type vibration wire pore pressure gauge, type vibration wire pore pressure gauge.The frequency that note records the first type vibration wire pore pressure gauge, the second type vibration wire pore pressure gauge is for the first time respectively f i, f j, record for the second time frequency and be respectively f i+1, f j+1, bring settlement formula into
S = k ( f j + 1 2 - f j 2 ) ρg + k ( f i 2 - f i + 1 2 ) ρg - - - ( 1 )
Wherein: S unit is mm; K is the sensor coefficient of pore pressure gauge, and unit is kPa/Hz 2;
F i, f j, f i+1, f j+1unit is Hz; ρ represents the density of air free water, is 1.0 × 10 3kg/m 3; G represents acceleration of gravity, and unit is m/s 2.
When observation liquid is while being water, be the low gas content amount guaranteeing in water, in order to avoid the degree of accuracy of settlement measurement is impacted, can adopt with the following method: clean water is boiled to 3 minutes, cooling, the unsuitable long storage time of cold boiling water, unless in container without air and airtight.When cold boiling water is proceeded to another tank by a container, can not pour into.While pouring into, can in air, form water column, by the water inlet of air band.Have special water-absorbing cylinder 11, water is sucked water storage cylinder 10 from bottom.While water being injected to sighting tube 3 from water storage cylinder 10, must be by water pipe from sighting tube bottom water outlet, water delivering orifice is progressively submerged in the water of sighting tube.After pipe system is poured water, oil is poured on sighting tube 3 waters surface to about 1mm thick, prevents that air from entering and being dissolved in the water from the water surface.
In a word, the utility model adopts buried metering system, does not disturb construction, can be widely used in various buildingss, especially can be used for directly using spirit-leveling instrument to measure.Precision of the present utility model is higher, and error is mm level.The frequency that survey crew only need to be measured two type vibration wire pore pressure gauges can complete surveying work, easy to operate, to measuring the requirement of personnel's technical quality far below using spirit-leveling instrument, therefore misoperation possibility reduces greatly.In addition, its size of type vibration wire pore pressure gauge is little, lightweight, highly sensitive, reliable operation, long service life.Because this device need not be measured water level, avoid also needing in disclosed flush type settlement measuring device untiing that sighting tube cap is measured water level and the moisture evaporation that may cause.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple equivalents to the technical solution of the utility model, these equivalents all belong to protection domain of the present utility model.
It should be noted that in addition each the concrete technical characterictic described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible array modes.
In addition, also can carry out combination in any between various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
