Description
Technical field
The utility model belongs to Geotechnical Engineering monitoring technical field, and being prefilled with filtrate more particularly, to one kind has anti-filter work(
The water level pipe of energy.
Background technology
In Geotechnical Engineering monitoring, level of ground water is most universal, most important groundwater monitoring key element.When carrying out underground water
During the observation of position, the embedded water level pipe that drills in the earth formation is often needed, then using the SEA LEVEL VARIATION in water-level gauge observed stage pipe.It is existing
By water level pipe it is general by bottom, sediment tube, filter pipe, close water pipe, Shu Jie, top cover etc. and constitute, wherein filter pipe is arranged at and contains
In water layer, with treatment hole, above connect and close water pipe, lower even sediment tube, is the most important part of water level pipe.
When underground water enters in filter pipe in water-bearing layer, fine grained silt particle can be brought into water level pipe, it is therefore desirable to take
Measure is filtered to silt particle.Existing method is, by filter pipe outsourcing geotextiles, filtrate to be filled between filter pipe and drilling, is led to
The synergy for crossing geotextiles and filtrate is filtered to silt particle, the water that the method is preferable for formation stability, depth is shallower
Position hole is more applicable.But when level of ground water buries relatively deep, it is necessary to when carrying out deep drilling, mud off need to often be used in engineering
Method pore-forming, hole bottom slurry is difficult to clean out after pore-forming, and the subject matter for facing is that filtrate is difficult to fill closely knit, causes filtering layer
Filter effect is deteriorated, and fine grain mud is easily penetrated into water level pipe, forms precipitation.If additionally, borehole wall is unstable (such as
Run into broken formation, water-sensitive strata, soft soil layer etc.), when from aperture between filter pipe and drilling fill filtrate when, easily
Because hole wall blocking, cave in or shrinkage cavity and caused by drilling and filter pipe between filtrate filling it is unreal in addition filling failure, it is difficult to
Play a part of filtering layer, the geotextiles for only relying on filter pipe outsourcing are difficult to prevent the fine grained in soil to enter in pipe completely, for a long time
Accumulation can cause ttom of pipe to precipitate a large amount of mud, and real water level cannot be observed when serious, cause water-level observation hole to be failed.Therefore,
Nowadays a kind of simple structure is lacked, the filtrate that is prefilled with reasonable in design has the water level pipe of anti-filter function, can be easy, quick complete
Installed into water level pipe, filter pipe docking is easy, and internal layer filter pipe, middle level filter pipe and outer metafiltration in filter pipe can be effectively ensured
The alignment of water pipe, by filling internal layer filtrate and filling outer layer filtrate, solves filter pipe because filtrate fills bad, filter effect
Water level pipe Problem of Failure caused by difference.
