Description
Technical field
The present invention relates to ocean dredge fill settlement monitoring field, particularly relates to a kind of applicable Yu Haiyang's hydraulic reclamation and make
The automation settlement monitoring device and method of land construction usage.
Background technique
Ocean land reclamation is that warp filling construction is formed using waterpower blast method, and hydraulic fill sand is that clay content is less
Medium coarse sand, often by take out the pressure pump of large junk will be underwater a large amount of in sand connect water and mix and be pumped to reclamation district, after water is discharged,
Medium coarse sand has become filling material；It is, in general, that the warp after hydraulic reclamation draining has the biggish compressed coefficient, shear strength
It is lower, have the characteristics that stronger rheological characteristic, thus dribble to pore water pressure, soil body effective stress is gradually increased, volume
After consolidation reduction, the soil body will generate biggish vertical deformation, form settlement of foundation.
Therefore, it in the land reclamation work progress of ocean, needs to be monitored reclamation district sedimentation and deformation, number is monitored with this
According to carrying out arrangement and method for construction adjustment, but since dredge fill reclamation district silt bearing capacity is poor, it is extremely difficult that personnel enter scene,
So that remote automation monitoring scheme has very big advantage and meaning.
For at present, traditional settlement monitoring mode for being applicable in the construction of Yu Haiyang's land reclamation is using magnet ring settlement gauge people
Work monitoring is drilled in predetermined hole location using drilling machine first such as method 1, and depending on hole depth is by sedimentation length of tube, aperture is proper with energy
Magnet ring is put into well to be preferred；It is then placed in sedimentation pipe, sedimentation pipe connects Shi Yaoyong nipple or socket joint type screw thread, keeps shell smooth,
And do not influence moving up and down for magnet ring；It is finally filled and is consolidated with swelling soil ball between sedimentation pipe and hole wall, until bottom first
The absolute altitude of magnet ring is again covered magnet ring on the clay face that sedimentation pipe sends to filling outside with specific purpose tool, is applied certain pressure, is made magnetic
In three iron claws insertion soil on ring, is then filled and consolidated to the absolute altitude of second magnet ring with swelling soil ball again, by above-mentioned side
Method installs second magnet ring, until the magnet ring completed in entire drilling is embedded；Or method 2, using before sedimentation pipe lower opening by magnetic
Ring is mounted on sedimentation pipe by designed distance, is isolated between magnet ring using sedimentation male union (or positioning ring), pore-forming
The sedimentation pipe with magnet ring is inserted in the hole afterwards；Magnet ring is forced to send with sedimentation pipe to designed elevation after joint is hampered；Then will
Sedimentation pipe pulls up 1m upwards, and magnet ring can be made not to be obstructed when moving in each 1m or so range above and below in this way, then settled with fine sand
It is filled between pipe and hole wall to nozzle absolute altitude.
But it should be noted that, it is above-mentioned to need to draw large junk or other heavy-duty machineries ability using magnet ring settlement gauge personal monitoring
Guarantee that personnel enter reclamation district, and consuming is huge, efficiency is extremely low.

Design principle of the invention simultaneously are as follows: as shown in Figure 5, wherein annular fluid reservoir when a1 indicates not settle
Position, the position of annular fluid reservoir when a2 indicates to settle, potential pressure between the two are Δ h, and Δ h is also referred to as soil body sedimentation
Amount, b indicate that supporting steel pipe, c indicate pressure transmitter, and d indicates firm soil layer, specifically, due to the soil around annular fluid reservoir
Body sedimentation annular fluid reservoir can be caused to generate sedimentation therewith, internal liquid level also decreases so that pressure transmitter and
The liquid level height difference of annular liquid storage jar liquid surface reduces；The liquid level height difference reduction fluid pressure that then pressure transmitter measures reduces this and subtracts
Caused by small amount is the height of liquid level (fluid reservoir) decline, therefore the corresponding height difference of amount that the pressure measured reduces is week
The settling amount of the soil body is enclosed, specifically, when liquid-level pressure variation switchs to the height difference of corresponding decline: assuming that the density of the liquid used is
ρ, h are liquid level, then the pressure that liquid generates is p=ρ gh, when soil body settling amount is Δ h, the then pressure that pressure transmitter measures
Power reduced value is Δ p=ρ g Δ h, so the specific settling amount of surrounding soil is known when measuring pressure change.
