Description
Technical field
The utility model is related to geotechnical engineering investigation and monitoring technical field, concretely relates to a kind of for underground water
Guard aperture, the hole sealing device of position monitoring, be particularly suitable for use in special rock soil（Such as swelling weak rock）, baleful geological processes（Such as karst）Area
Domain.
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
True property is assay place foundation stability and the foundation of hydrostatic water table.Level of ground water refers to the height of the water surface in underground reservoir
Journey, can be divided into drilling and disclose the initial water level found first during water-bearing layer, 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 use seamless geology steel tube）, a drilling need to be with a contour guard aperture pipe.
2. the stage is monitored：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 influence is eliminated every time before measurement.It is steady measuring
Determine after water level, also need to set monitoring holes, draw the level of ground water in place is influenceed size, seasonal variety situation, institute by rainfall
Survey the parameters such as peak level.
3. sealing of hole stage：Uniformly start sealing of hole after all level of ground water parameters in place are obtained.It is general first to transfer thing along pipe
Material（Such as stopper）As plug, completely cut off water-bearing layer, reuse after grouter cement injection slurries, grout cures using rig
Pull out guard aperture pipe.
The three phases of water table measure are both needed to complete using guard aperture pipe, during which can not extract guard aperture pipe.Because seamless
Geology steel tube cost is of a relatively high, in the monitoring stage, there is a situation where survey crew's violation operation for the reduction effective amount of guard aperture：
Surveyed fixed level extract guard aperture pipe use it for other drilling, lack set monitoring holes process, simply by search phase
Pass data draws inaccurate monitoring parameter.The parameter can not reflect place situation strictly according to the facts, be not reaching to the purpose of monitoring, directly
Influence follow-up work.
In the sealing of hole stage, because guard aperture pipe only has guard aperture function, it 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.Isolation water-bearing layer completely may not during packing
The slurries for making underground water that sealing of hole is poured in or be used in from drilling are leaked in water-bearing layer, especially in special rock soil, bad
Geologic process region, easily causes foundation pit construction water burst, foundation softening, induces the ground such as periphery karst ground subsidence and polluted underground water
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.
Water table measure, envelope can not be effectively ensured because cost is of a relatively high, function is single for conventional steel guard aperture pipe
The problem of hole quality, inventing a kind of guard aperture, hole sealing device for water table measure has important engineering significance.
Utility model content
Technical problem to be solved in the utility model is conventional steel guard aperture pipe because cost is of a relatively high, function is single not
The problem of water table measure, sealing quality can be effectively ensured.
In order to solve the above technical problems, technical solution adopted in the utility model is：One kind is used for water table measure
Guard aperture, hole sealing device, 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 below device, 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
Soakaway trench is blocked, avoids slurries from entering water-bearing layer in sealing of hole.
The hole sealing tube is located in the middle part of device, including hypomere and epimere.Hypomere connects with soakaway trench, caliber be device in most
Greatly, for fixed support whole device, hypomere bottom is wrapped up with soakaway trench joint outer wall by flax silk, and flax silk can increase hole sealing tube
External diameter, makes it 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 be flowed out from hole, the gap filled up between device and borehole wall.
The guard aperture pipe is located above device, and top is above the ground level, and can prevent hole wall collapse and earth's surface soil from falling.
The Guan Yuguan, which connects, uses adhesive means.
The soakaway trench, hole sealing tube, guard aperture Guan Jun use PE（Polyethylene）Pipe.
The water-permeable filter layer uses geotextiles.
The beneficial effects of the utility model are：
It is with low cost.Institute using PE materials in the case of reaching same effect compared with original guard aperture pipe cost less than ten
/ mono-.
Feature is strong.Have guard aperture, sealing of hole function concurrently, be alternative original guard aperture pipe, plug completion using only a kind of device
The three phases of water table measure, solve the problem of original guard aperture pipe function is single.
It is easy to use, shorten the prospecting duration, reduce risk.Drilling stage, survey crew often completes a drilling, you can put
Enter the present apparatus, using present apparatus guard aperture, can will lay, rise and pull out the unification of guard aperture pipe two procedures, shorten duration, reduction and move rig
Security risk.
Environmental protection.The geologic Environment Problems such as underground water pollution caused by packing effect difference can effectively be prevented.
It is easy to spread.The utility model on-the-spot purchasing material and can be connected；The used more former seamless geology steel tube of PE materials
It is easy to buying, also with antirust treatment, the low advantage of production power consumption need not be done.
