Description
Technical field
The present invention relates to geotechnical engineering investigation and monitoring technical field, concretely relate to a kind of for level of ground water prison
Guard aperture, the hole sealing device of survey and combinations thereof method, is particularly suited for special rock soil（Such as swelling weak rock）, baleful geological processes
（Such as karst）Region.
Background technology
The measurement of level of ground water and the important content that monitoring is geotechnical engineering investigation.The authenticity and standard of level of ground water
Really property is the foundation of assay place foundation stability and hydrostatic water table.Level of ground water refers to the height of the water surface in underground reservoir
Journey, can be divided into drilling disclose water-bearing layer when find first initial water level, vary less and rise or fall trend without system
Fixed level etc..
At present, the measurement of level of ground water is generally divided into drilling, monitoring, sealing of hole three phases with monitoring.
1. drilling stage：Use rig fixed-point drill on the ground, to prevent hole wall collapse, need according to place actual requirement
Guard aperture pipe is laid while drilling（Typically adopt seamless geology steel tube）, a drilling need to match somebody with somebody a contour guard aperture pipe.
2. monitor the stage：Need unified measurement initial water level, fixed level.Initial water level is easy to measure, and fixed level is usual
Start measurement after the completion of all drillings in place, be both needed to treat that water level recovers and water level affects to eliminate every time before measurement.It is steady measuring
After determining water level, also need to arrange monitoring holes, draw the level of ground water in place is affected size, seasonal variety situation, institute by rainfall
Survey the parameters such as peak level.
3. sealing of hole stage：It is unified after all level of ground water parameters in place are obtained to start sealing of hole.It is general first to transfer thing along pipe
Material（Such as stopper）As plug, completely cut off water-bearing layer, reuse grouter cement injection slurries, risen using rig after grout cures
Pull out guard aperture pipe.
The three phases of water table measure are both needed to be completed using guard aperture pipe, and period can not extract guard aperture pipe.Because seamless
Geology steel tube cost is of a relatively high, in the monitoring stage, there is survey crew to reduce the situation of the effective amount of guard aperture and violation operation：
Surveyed fixed level extract guard aperture pipe use it for other drilling, lack arrange monitoring holes process, simply by search phase
Pass data draws inaccurate monitoring parameter.The parameter can not strictly according to the facts reflect place situation, be not reaching to the purpose monitored, directly
Affect follow-up work.
In the sealing of hole stage, because guard aperture pipe only has guard aperture function, need to separately set plug and complete packing.Workmen is the side of asking
Just, packing work is often ignored, not sealing of hole or the plug sealing of hole from sealing difference.Not completely cutting off water-bearing layer completely during packing may
The slurries that underground water poured in or be used in sealing of hole from drilling are made to leak in water-bearing layer, especially in special rock soil, bad
Geologic process region, easily causes foundation pit construction water burst, foundation softening, induction periphery karst ground subsidence and polluted underground water etc. ground
Matter environmental problem, wherein periphery karst ground subsidence and polluted underground water mostly occur after the completion of water table measure, it is difficult to chase after
Look into and remedy, there is greatly safety in production hidden danger.
For conventional steel guard aperture pipe because cost is of a relatively high, single function can not be effectively ensured water table measure, envelope
The problem of hole quality, invents a kind of guard aperture, hole sealing device for water table measure and combinations thereof method and has important work
Cheng Yiyi.
The content of the invention
The technical problem to be solved is conventional steel guard aperture pipe because cost is of a relatively high, single function can not have
Effect ensures water table measure, the problem of sealing quality.
To solve above-mentioned technical problem, the technical solution used in the present invention is：A kind of shield for water table measure
Hole, hole sealing device and combinations thereof method, is connected successively from the bottom to top by soakaway trench, hole sealing tube, the part of guard aperture pipe three.
The soakaway trench is located at device lower section, including outer tube, inner tube, plug and water-permeable filter layer.Outer tube, inner pipe wall are opened
There is permeable hole, porous allows the underground water in water-bearing layer to penetrate into device, draws the related data of level of ground water.Plug position
In outer pipe bottom, insulating effect is played.Water-permeable filter layer be located between inner tube, outer tube, monitoring when porous, prevent hole wall soil
Blocking soakaway trench, avoids slurries from entering water-bearing layer in sealing of hole.
The hole sealing tube is located at device middle part, including hypomere and epimere.Hypomere connects with soakaway trench, caliber be device in most
Greatly, whole device, hypomere bottom is supported to be wrapped up by flax silk with soakaway trench joint outer wall for fixed, flax silk can increase hole sealing tube
External diameter so as to be easy to placement, while avoiding slurries from entering underground reservoir in grouting.Epimere connects with guard aperture pipe.Upper-lower section
Grout hole is provided with tube wall, in grouting, slurries can be made to flow out from hole, fill up the gap between device and borehole wall.
The guard aperture pipe is located at device top, and top is above the ground level, and can prevent hole wall collapse and earth's surface soil from falling.
The Guan Yuguan connects using adhesive means.
The soakaway trench, hole sealing tube, guard aperture Guan Jun adopt PE（Polyethylene）Pipe.
The water-permeable filter layer adopts geotextiles.
The invention has the beneficial effects as follows：
It is with low cost.Institute using PE materials in the case where same effect is reached compared with original guard aperture pipe cost less than ten/
One.
Feature is strong.Have guard aperture, sealing of hole function concurrently, be that alternative original guard aperture pipe, plug are completed only using a kind of device
The three phases of water table measure, solve the problems, such as original guard aperture pipe single function.
It is easy to use, shorten prospecting duration, reduce risk.Drilling stage, survey crew often completes a drilling, you can put
Enter this device, using this device guard aperture, can will lay, rise and pull out the unification of guard aperture pipe two procedures, rig is moved in reduction of erection time, reduction
Security risk.
Environmental protection.The geologic Environment Problems such as the underground water pollution that causes because of packing effect difference can effectively be prevented.
It is easy to spread.The present invention on-the-spot purchasing material and can connect；Institute is easy to using the more former seamless geology steel tube of PE materials
Buying, also with antirust treatment, the production low advantage of power consumption need not be done.
