Abstract
The invention discloses a kind of soil body delaminating deposition quantity monitoring methods, sedimentation ring are fitted on bellows, logical heart sedimentation pipe is inserted in bellows；Then the sedimentation pipe for being set with sedimentation ring and bellows is embedded to vertically in tested soil layer, the pressure generated when being tested solum settlement settles flexible synchronize with tested soil layer of bellows, settles so that sedimentation ring is synchronized with tested soil layer；Since bellows-sheathed is on the outside of logical heart sedimentation pipe, and bellows inner wall smooth, when with solum settlement, logical heart sedimentation pipe is small to the frictional resistance of bellows, sinking on it, it is smaller to influence, and can to avoid between the sedimentation ring and sedimentation pipe of traditional batch sedimentometer enter soil particle, seriously affect the adverse effect that sedimentation ring sinks with soil layer, to ensure that concertina type sedimentation ring can sink as soil layer to be measured is synchronous, the accuracy of the measurement result of the soil body delaminating deposition amount monitoring system based on concertina type sedimentation ring ensure that.
Description
Technical field
The invention belongs to civil engineering quality-monitoring instrument, in particular to a kind of soil body delaminating deposition quantity monitoring method.
Background technique
Reclaiming land around sea or soft clay area engineering etc. are through the method Ground Treatment frequently with vacuum preloading.The mistake of vacuum preloading
Journey, settlement of foundation is larger, needs to be layered measurement soil body sedimentation deformation and determines construction speed and discharge time, it is ensured that constructed
Journey meets design requirement.In addition, in Groundwater Lowering During Deep Foundation Pit Excavation process, it is understood that there may be partial pressing's head is excessive, causes part big
The differential settlement of deformation, so being also required to soil body delaminating deposition amount to assess dewatering effect.Soil body delaminating deposition is to pass through soil
Sedimentation mark observation is buried in vivo, i.e., is observed using Level Height measurement method.Observation must run through entire Soft Soil Layer, survey at one
The solum settlement along pipe depth direction is measured on pipe.
Magnet ring type sedimentometer is more commonly used layered settlement observation instrument, is made of magnet ring, conduit, gauge head.Conduit number
Value is embedded in soil, buries magnet ring at a certain distance on conduit, and magnet ring settles simultaneously with the soil body, measures magnet ring using electromagnetism gauge head
It is initial and sedimentation after position, the difference between the two, that is, soil layer delaminating deposition amount.Traditional its magnet ring of magnet ring type laminated settlement meter with
Conduit is connected, and is embedded in soil together, and magnet ring and conduit have certain interval.As the soil body settles, full of soil between magnet ring and conduit
Particle, magnet ring are stuck, and can not settle with the soil body, so that mistake occurs in observed result.
Summary of the invention
It is an object of the invention to overcome existing magnet ring type sedimentometer to influence observation knot because blocking soil between magnet ring and conduit
The problem of accuracy of fruit, provides a kind of soil body delaminating deposition quantity monitoring method.
The present invention is achieved by the following technical solutions:
A kind of soil body delaminating deposition quantity monitoring method, this method is using sedimentation ring, bellows, logical heart sedimentation pipe and dedicated survey

The cone seal head of sealing is set on the lowermost end mouth of logical heart sedimentation pipe；
Step 2: punching stratum, by the assembled logical heart sedimentation pipe with bellows and sedimentation ring of step 1
In vertical embedment hole, the cone seal head of logical heart sedimentation pipe lowermost end reaches underground and does not occur to settle rock stratum position, bellows and
Logical heart sedimentation pipe top exposes soil body surface layer；
Step 3: after sedimentation ring is embedded in stratum, sedimentation ring is embedded in tested soil layer, the pressure generated when being tested solum settlement
Power settles sedimentation ring also with tested soil layer is synchronous with bellows；
Step 4: when needing to measure solum settlement situation, the magnetic induction gauge head end that is equipped with of special measurement tape is put into
It in logical heart sedimentation pipe, holds tape and is slowly moved down by magnetic induction gauge head, when magnetic induction gauge head reaches sinking in soil layer
When dropping ring burial place, the buzzer in receiver will beep, and manually read special measurement tape at this time in the logical heart
Depth dimensions at sedimentation pipe nozzle are the distance length that the sedimentation ring distance leads to heart sedimentation pipe nozzle, by the linear measure longimetry
Difference between value and the measured value at previous time point is soil layer where the steady sedimentation ring in the sedimentation of this period
Amount.
In the above-mentioned technical solutions, the sedimentation ring includes a ring sleeve, and the insertion of ring sleeve inner tubal wall is provided with one
Magnet circle is enclosed, for triggering the magnetic induction part in sedimentometer probe, settles and is also connected with wire on the ring sleeve of ring, sink
Drop ring set is located on bellows, and will be settled ring by wire and fixed with bellows.
In the above-mentioned technical solutions, the equal length of the initial length of bellows and logical heart sedimentation pipe.
In the above-mentioned technical solutions, lubricant is filled between bellows and logical heart sedimentation pipe.
The advantages and benefits of the present invention are:
The present invention will settle ring on bellows, and logical heart sedimentation pipe is inserted in bellows；Then it is heavy to be set with
The sedimentation pipe of drop ring and bellows is embedded to vertically in tested soil layer, and the pressure generated when being tested solum settlement makes bellows flexible
It is settled with tested soil layer is synchronous, so that sedimentation ring is settled with tested soil layer is synchronous；Since bellows-sheathed is in logical heart sedimentation pipe
Outside, and bellows inner wall smooth, when with solum settlement, logical heart sedimentation pipe is small to the frictional resistance of bellows, sinks to it
Influence is smaller, and can be to avoid soil particle is entered between the sedimentation ring and sedimentation pipe of traditional batch sedimentometer, and it is heavy to seriously affect
The adverse effect that drop ring sinks with soil layer ensure that ensure that concertina type sedimentation ring can sink as soil layer to be measured is synchronous
The accuracy of the measurement result of soil body delaminating deposition amount monitoring system based on concertina type sedimentation ring.
