Description
Technical field
The utility model relates to a kind of dam seepage line observation device, relates in particular to a kind of device that is used to observe mine tailing storehouse dam seepage line, is specially adapted to the mine tailing storehouse of adopting upper reaches formula mine tailing to build a dam, and realizes the observation of dam seepage line.
Background technology
The important element that the mine tailing storehouse produces as the mine also is the major hazard source and the environomental pollution source in mine simultaneously.The mine tailing storehouse of adopting upper reaches formula mine tailing to build a dam is lower owing to cost; Adopt on a large scale in China; But relatively low because of its security, higher to maintenance, the management expectancy of dam body, in recent years, the mine tailing storehouse security incident that adopts upper reaches formula mine tailing to build a dam takes place again and again; Business economic is sustained a loss, more the people's lives and property safety and harmonious ecologic environment are caused serious harm.
For the mine tailing storehouse that upper reaches formula mine tailing is built a dam, the height of saturation is directly connected to the stable and security of dam body, obtains saturation buried depth data in time, exactly, to distinguishing mine tailing storehouse running status, guaranteeing that mine tailing storehouse safety is significant.
At present, the tailing dam saturation line monitoring has two kinds of methods usually: a kind of is the piezometric tube of burying right quantity underground, obtains the height of saturation through artificial in-site measurement piezometric tube middle water level; Another kind is to bury special sensor underground; Through the boring of Drilling in dam body, be placed on the osmometer that has pressure transducer in the boring, through the pressure of osmometer measurement; Convert head height again into, can obtain dam body or around the saturation height on dam in conjunction with fitting depth and aperture height.
Find in the practical application that there is following problem in existing tailing dam saturation line monitoring means:
(1) standardization, mouth of pipe rainfall, tenure of use, the reservoir level installed easily of piezometric tube sensitivity skyrockets and falls the influence of factors such as variation suddenly, causes the dam seepage line error of observation data bigger;
(2) because sensor is positioned at mine tailing storehouse physical environment state, and working environment is comparatively abominable, the precision of sensor and duty are subject to factor affecting such as thunder and lightning, humidity, rainfall, temperature variation, installation, cause the distortion of dam seepage line observation data.
Summary of the invention
In order to overcome the above-mentioned defective that existing tailing dam saturation line monitoring system exists; The utility model provides a kind of device that is used to observe mine tailing storehouse dam seepage line; Be applied to tailing dam saturation line observation; Have reliability height, laying is simple, easy to operate, permanance is high characteristics, the mine tailing storehouse dam seepage line observation needs that particularly suitable upper reaches formula mine tailing is built a dam.
For realizing the above-mentioned purpose of the utility model, the utility model is a kind of to be used to observe the device of mine tailing storehouse dam seepage line to adopt following technical scheme to realize:
The utility model is a kind of to be used to observe the device of mine tailing storehouse dam seepage line to contain the steel pipe that is laid in the tailing dam dam body.The anti-filter of steel pipe outsourcing geotextile is also firm with the flax silk colligation, adopts the coarse sand joint filling on every side; The bottom of steel pipe is that sand setting pipeline section, middle part are the drainage pipeline section, and the top part of steel pipe is exposed the face of land and adopted screw thread to be connected with the steel plug, realizes that the steel pipe mouth is airtight; The shutoff of immersion oil stopper is adopted in the bottom of steel pipe; Drainage pipeline section at steel pipe is laid presbyopia.
The quantity of the presbyopia that the drainage pipeline section of said steel pipe is laid on the circle of same cross section is 6, and waits the radian layout; The aperture φ of presbyopia is 8mm, longitudinal pitch 50mm.
Said steel pipe length is got 6m～12m by mine tailing storehouse grade; Said sand sediment pipe segment length is 0.8～1.2m, and the filter pipe segment length is 1.8～3.0m.
The utility model is a kind of be used to observe the device of mine tailing storehouse dam seepage line to adopt above technical scheme after, have following effect:
(1) this device has the accuracy of observation height, and data acquisition is simple, is applicable to the upper reaches formula mine tailing characteristics of building a dam preferably;
(2) this device has and is convenient to observation, and tenure of use is longer, and it uses the characteristics do not receive factor affecting such as weather, temperature, installation;
(3) this device has easy mounting, is convenient to augment at any time, can increase the characteristics of timely laying with tailing dam.
