Background technique
Currently, common deep vertical monitoring point for displacement mostly uses one whole reinforcing bar or self-control iron in engineering, work as needs
It just needs to process respectively when laying different depth monitoring point, versatility is poor；And gauge head at the top of common monitoring point and bottom are not
Any specially treated is done, it, can be to monitoring accuracy due to standing ruler people, vertical ruler position difference every time when the out-of-flatness of ruler face is stood at top
It affects greatly；And bottom does not process and only relies on monitoring point itself and periphery soil body frictional force come when reacting stratum settlement,
Monitoring point and the periphery soil body easily occurs to be detached from, monitoring point can not actual response soil deformation the case where, seriously affect the essence of monitoring
Degree.
The utility model patent of Publication No. CN203274723U discloses deep vertical displacement monitoring regarding to the issue above
Point device, it is characterised in that: including gauge head, measuring staff, sleeve；Gauge head, measuring staff are connected through a screw thread, and measuring staff and sleeve pass through measuring staff
It is connect with sleeve connector.Further, the measuring staff is that one section of measuring staff or two sections or more measuring staff are connected by measuring staff connector
It forms.Further, the measuring staff makes tapered with sleeve connector bottom.Further, the gauge head is fabricated to sphere.
Although monitoring point length can be arbitrarily adjusted in above scheme, at the same gauge head and monitoring point bottom have been carried out it is special
Change processing, improves measurement accuracy and effect, but gauge head, measuring staff, measuring staff connector, measuring staff and sleeve connector pass through rotation
Stubborn mode is fixed, and stability is poor, and generally there are underground water for soil body deep layer, and the soil body is more moist, and moisture, which is easy to corrode, to be connected
Fitting under the extruding of the soil body, and then causes measuring staff to loosen due to the reason that its stability is poor, seriously affects the heavy of the soil body
Accuracy of observation drops, although in addition the setting of sleeve can increase the attachment force between the soil body, due to the tubular of itself
Characteristic, attachment force increase is limited, is still easy to happen the phenomenon that being detached from the soil body, and drill to be embedded to sleeve in construction

When combination, paying attention to for a pair of displacement closing piece 6 being aligned with a pair of of locked groove 7 respectively, displacement closing piece 6 initially enters the vertical section of locked groove 7,
Displacement closing piece 6 slides decline in vertical section, and a pair of of about 101 sub bar is docked and fitted closely, and rotates clockwise upside at this time
Sub bar 101, displacement closing piece 6 be transitioned into horizontal segment out of vertical section and be moved to from magnet block 13, magnet block 13 will displacement lock
The absorption of block 6 is fixed；Then threaded block 8 is screwed in threaded hole, while locating rod 10 is driven to be inserted into the positioning on displacement closing piece 6
In hole 11, the positioning to displacement closing piece 6 is realized, complete the combination between a pair of of sub bar 101, and combination is surplus in the same manner
Remaining sub bar 101 and looking for flat 2.
After having openning hole at the scene, device is vertically disposed in hole, it is levelling by looking for flat 2, backfill rammer is carried out after the completion
In fact, when measurement, by being put on the basis of the fixed point of setting as starting elevation, the elevation of periodic measurement gauge head 3, according to gauge head 3
Elevation changes it can be learnt that the deep vertical of the soil body is displaced.
It applies the technical scheme of the present invention, effect is:
The device of the invention, which can effectively prevent between sub bar, to be there is gap monitoring result is caused the case where deviation occur,
Guarantee that the result of monitoring is accurate and reliable, can effectively prevent the intracorporal soil of soil and moisture attack device by the way that sealing element is arranged
