Abstract
The utility model relates to an underground hydrological observation hole, which is characterized by comprising a line-shaped underground observation hole which points at a point to be observed from the middle section of mining and is internally provided with a sleeve equal to the hole in length; the gaps between the sleeve and the hole walls are filled with slurry or colloid in a sealing manner; and one end of the sleeve, positioned at the middle section of mining, is provided with a water pressure measuring device. The underground hydrological observation hole has the benefits of: being not influenced by position, having real observed data, having no worry about the damage of the observation hole, being capable of carrying out long-term hydrological investigation by mines, carrying out water discharging experiments under a well by the hole and having simple method. In addition, underground hydrological observation hole is easier to observe water pressure and water level compared with the ground observation hole, the total cost is lower than that of the ground hydrological observation hole, and as drilling is carried out under ground, the material of rocks of the drilling hole is more single and easy to drill.
Description
(1) technical field
The utility model relates to underground construction and field of mining, particularly a kind of underground hydrological observation wells.
(2) background technology
The anti-sealing that is mainly in big flood mine enters the tunnel, in this case, control to water level hydraulic pressure is very necessary, this just need carry out hydrological observation often, now general big flood mine is employed to be the ground hydrological observation wells, exploratory hole also need be measured the fixed level in phreatic initial water level, aquifer except that need satisfy the requirement in generaI investigation hole, take water sample to identify water quality, measure hydrogeological parameters such as the water yield and water temperature.Be the correct groundwater storage of estimating, need carry out also that layering is drawn water, layering observation, draw water in full hole or the pumping of group wells test, in order to divide aquifer, group, observe the phreatic cone of depression and groundwater velocity, the flow direction, with the hydraulic property in research aquifer, each aquifer each other and the hydraulic connection between aquifer and the surface water.In order to reach the goal,, or bore larger-diameter boring, be lowered to operations such as sleeve pipe, filter pipe, throwing gravel, sealing, well-flushing then, carry out the observation of pumping test and groundwater dynamic again, can be used as water supply well after the observation often the exploratory hole enlarged-diameter.In solid mineral exploration district, the boring of also often selecting some is as the hydrogeologic prospecting hole, for mining area exploitation provides hydrogeologic data.The bore diameter that draws water of exploratory hole is generally 150～350 millimeters.By the boring periodic observation groundwater table degree of depth, understand variation of groundwater dynamic in the large tracts of land scope.When carrying out pumping test, need many group peepholes to carry out water level and dynamic observe in the mining area.In the part exploratory bore-hole after obtaining hydrogeologic data, also can make peephole uses, but now along with development of mines, the increase of surface structures, will have influence on construction on the ground, and because a variety of causes, hydrological observation wells is destroyed by the people easily even is discarded on the ground, so just hydrological observation is produced very big influence, can't reach the purpose of carrying out hydrology prospecting for the mine for a long time.
(3) summary of the invention
The utility model provides a kind of underground hydrological observation wells of carrying out hydrology prospecting for the mine for a long time in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
Underground hydrological observation wells of the present utility model, its special character is: comprise by the mining stage casing and point to the underground peephole of straight line shape that is observed a little, the sleeve pipe suitable with this hole length is installed in the underground peephole, sealing is filled with slurry or colloid in the space between sleeve pipe and the hole wall, and the end that sleeve pipe is positioned at the mining stage casing is equipped with the survey hydraulic devices.
Underground hydrological observation wells of the present utility model, underground peephole is positioned at horizontal direction.
Underground hydrological observation wells of the present utility model, perhaps, underground peephole is positioned at incline direction.
The beneficial effects of the utility model are, are not subjected to the influence of position, and the data of observation are true, do not worry that peephole is destroyed, can carry out hydrology prospecting for a long time for the mine.And can utilize the hole experiment that discharges water in the down-hole, its method is simple, and than easier observation water setting-out position, ground observation hole, whole cost is than hydrological observation wells is low on the ground, owing to creep into underground, boring rock stratum material is more single, is easy to probing.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.Fig. 2 is step 1 operation chart.Fig. 3 is step 2 operation chart.
Among the figure, 1 hydrological observation well, 2 ground, 3 mining stage casings, 4 underground peepholes, 5 are observed a little, 6 sleeve pipes, border, 7 tunnel.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Underground hydrological observation wells of the present utility model, comprise by 3 sensings of mining stage casing and be observed a little 5 the underground peephole 4 of straight line shape, the sleeve pipe 6 suitable with this hole length is installed in the underground peephole, sealing is filled with slurry or colloid in the space between sleeve pipe and the hole wall, and the end that sleeve pipe is positioned at the mining stage casing is equipped with the survey hydraulic devices.Underground peephole 4 is positioned at horizontal direction.Perhaps, underground peephole 4 is positioned at incline direction.
Underground hydrological observation wells of the present utility model, move into the hydrological observation wells on ground underground, it mainly carries out hydrological observation by underground peephole 4, after can holing and long-term place of not being damaged, determine the place in mining stage casing 3, border, tunnel 7 etc., boring, setting of casing extend into sleeve pipe and is observed a little 5 places, then sealing, pressing force tables etc. are surveyed hydraulic devices, so just can long-term observation hydrology hydraulic pressure.No longer need from ground the 2 civilian observation wells 1 of fetching water.
Operating procedure is as follows:
1. make a call to a hydrological observation wells up to the place that will observe in the stage casing of needs observation.Notice that boring is parallel creeping into, if boring has the inclination angle, need record, the absolute altitude of actual observation point is analyzed according to creeping into length in the back.See Fig. 2.
2. then sleeve pipe is led to observation point, the space with the sealing of methods such as slip casting, colloid, can not be left in the space between hole wall and the iron pipe, pressure tester is installed in the iron pipe hole is again got final product.See Fig. 3.
Claims (3)
1. underground hydrological observation wells, it is characterized in that: comprise by mining stage casing (3) and point to the underground peephole of straight line shape (4) that is observed point (5), the sleeve pipe suitable with this hole length (6) is installed in the underground peephole, sealing is filled with slurry or colloid in the space between sleeve pipe and the hole wall, and the end that sleeve pipe is positioned at the mining stage casing is equipped with the survey hydraulic devices.
2. underground hydrological observation wells according to claim 1 is characterized in that: underground peephole (4) is positioned at horizontal direction.
