Abstract
The utility model discloses a multifunctional geotechnical engineering inclinometer tube, which relates to an inclinometer tube for a monitoring technology of geotechnical engineering stability. The multifunctional geotechnical engineering inclinometer tube structurally includes that the tube wall of an inclinometer tube (1) is provided with a water inlet orifice (2), a filter screen is arranged in the water inlet orifice (2) and fixedly sealed by a gasket (4) and an adhesive agent (5), the water inlet orifice (2) is composed of two concentric circular holes, and the inner diameter of the inner concentric circular hole is smaller than that of the outer concentric circular hole. The multifunctional geotechnical engineering inclinometer tube has simple structure, good effect, easy implementation and reduced cost, which is adapted for inclinometer tubes of bore-hole displacement and water level co-bore measurement.
Description
Technical field
The utility model relates to a kind of deviational survey pipe that is used for Geotechnical Engineering STABILITY MONITORING technology, relates in particular to a kind of multi-functional Geotechnical Engineering deviational survey pipe.
Background technology
As everyone knows, in the Geotechnical Engineering side slope, slope slide deep deformation rule is to estimate the important indicator of slope stability, and the inner bury of groundwater of gliding mass is the key factor that influences slope stability.Therefore, for geotechnical engineering construction safety and security of operation in the future, must monitor in real time the distortion and the underground water table in rock mass deep.
At present, the method that is widely used in the displacement of monitoring deep rock mass in the Geotechnical Engineering is to utilize clinograph, its measuring process is: at first bore a boring at the rock mass position of needs monitoring, and in boring, bury the deviational survey pipe underground, tiltmeter is put in the deviational survey pipe then, can be measured the horizontal shift of boring.Long-term timing is measured, and measurement result is carried out analysis-by-synthesis, draws the Changing Pattern of deep rock mass displacement.The method of measuring drilling water level is a lot, as electrode method, lining rope method etc.But after the deviational survey pipe was buried in boring underground, underground water can not enter in the deviational survey pipe, just can't continue to measure easily the water level in this boring.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned shortcoming and defect that prior art exists, realize the requirement of existing engineering, a kind of multi-functional Geotechnical Engineering deviational survey pipe is provided, this deviational survey pipe combines with existing clinograph and device for measuring drilling water level, both can measure the horizontal shift of boring, simultaneously also can measure drilling water level, realize the same-pore measurement of boring horizontal shift and water level.
The purpose of this utility model is achieved in that
As Fig. 1,2, structure of the present utility model is: the tube wall of deviational survey pipe is provided with the inlet opening, is mounted with filter screen in the inlet opening, and filter screen is by pad and tackifier fixing seal.
Principle of work of the present utility model is:
Underground water enters in the deviational survey pipe by filter screen from the inlet opening, makes interior water level of pipe and drilling water level reach sustained height, and water level just can be known drilling water level in the measuring tube.
The utlity model has following advantage and good effect:
1, simple in structure, effective.Combine with existing clinograph and device for measuring drilling water level with the utility model, both can measure the horizontal shift of boring, also can measure drilling water level simultaneously, be easy to just realize the same-pore measurement of boring horizontal shift and water level.
2, implement to reduce cost easily.Use the utility model to realize boring horizontal shift and water-level same-pore measurement, make to measure to become simple and direct, reduced quantities, reduced cost.
3, the utility model is applicable in the deviational survey pipe of drilling displacement and water-level same-pore measurement.

The 5-tackifier.
Embodiment
Below in conjunction with drawings and Examples to the utility model further instruction:
One, specific implementation method
The utility model is embedded in the boring of having accomplished fluently, fills closely knit with particle diameter greater than the fine sand in filter screen 3 apertures between boring and the deviational survey pipe 1.Underground water in the boring can enter in the deviational survey pipe 1 from inlet opening 2, treats to adopt drilling water level measuring method commonly used behind the stable level, as electrode method, lining rope method etc., just can measure drilling water level; Use tiltmeter can measure the boring horizontal shift simultaneously, realize the same-pore measurement of boring horizontal shift and water level.
Two, each parts
1, the deviational survey pipe 1
As Fig. 1,2, deviational survey pipe 1 is a kind of deviational survey pipe commonly used, and the listing product is arranged.
2, the inlet opening 2
As Fig. 1,2, inlet opening 2 is made up of two concentric circle holes, and the internal diameter of interior concentric circle holes is less than the internal diameter of outer concentric circle holes.
3, filter screen 3
4, pad 4
5, tackifier 5
Tackifier 5 is a kind of moisture-proof adhesive, and metal and plastic or other material are had good bonding and sealing effectiveness.
