Abstract
The invention discloses a repairing method for plugging wells. The repairing method includes the following steps of 1), filling of an exploded agent; 2), exploded operation; 3), removal operation. The exploded agent with a protective unit and placed in underground water is ignited by the aid of a power source, then strong expansion, pressure and high temperature close to 900 DEG C are generated, rust, scale and various of plugs attached to pipe walls and bottoms of the wells are forcibly removed and discharged out of the wells with water flow through water pumps, and the optimum efficiency of repairing of the wells can be achieved. Air vents evenly distributed on the barrel wall of a protecting barrel enable expansive force to be uniformly released, and damage to a well casing due to the fact that the expansive force is released in a concentrated manner is effectively avoided; the repairing method is simple in repairing equipment, low in repairing cost, time saving and labor saving, convenient and rapid to operate, pollution-free, efficient, good in effect and applicable to the wells different in aperture size within well depth ranging from 10 to 200 meters and water depth ranging from 2-50 meters.
Description
Technical field
The present invention relates to a kind of maintenance of well, multiple new and maintenance technology, be specifically related to a kind of restorative procedure that stops up well.
Background technology
China's rural potable water majority is still used the little well of unshared housing, in addition the well irrigation Rice Cropping increasing rapidly in recent years and green house of vegetables plantation, well quantity increases severely, increase along with service time, no matter well casing adopts iron pipe or adopts concrete pipe, there is scale or incrustation scale silting phenomenon in capital in various degree, shaft bottom also can be because silting produces clogging, cause water outlet smooth to such an extent as to can not water outlet, peasant household also taked some processing methods, with timber or timber top cover, load onto iron head, from aboveground, to down-hole, impact, can there be some alleviations, but shaft bottom is piled up the silt of silting and is rushed more real and more real, these ways are to cure the symptoms, not the disease, can not fundamentally solve the blockage problem of well, peasant household have to very reluctantlyly forget the well of destroying not water outlet, according to the preliminary statistics, only with regard to northern areas such as Heilungkiang, the well of scrapping every year accounts for the 6%-7% of well sum, annual well of newly drilling accounts for total 8%-9%, again well-digging, every mouthful of well saliva well will spend 5,000 to 10,000 yuan, also to waste a large amount of man power and materials, therefore peasant household urgently wishes to have a kind of solution to stop up the good restorative procedure of well.
Summary of the invention
The object of the present invention is to provide a kind of restorative procedure that stops up well, thoroughly solve in well casing and the blockage problem in shaft bottom, cost of investment of the present invention is low, safe and reliable, quick environmental protection, and economic benefit and social benefit are remarkable.
For achieving the above object, technical scheme of the present invention is: a kind of restorative procedure that stops up well comprises the steps:
1, load swollen detonator
First the ignition part of ignition device is put into core cylinder bottom, getting 20-25 gram of swollen detonator pours in cylinder, make swollen detonator cover the ignition part of ignition device, then get thin loess and cover on swollen detonator, the thickness of loess is 3-3.5 centimetre, then use the compacting of flat-top waddy, get paraffin or pitch 10-15 gram, after dissolving, pour in upright core cylinder, on loess formation as waterproofing course, cooling through 20 minutes, filling completes;
2, swollen quick-fried operation
The core cylinder filling is arranged in the protection bucket of obturator and is spirally connected and fix, the lifting line of the electric wire of the ignition device of core cylinder and obturator is twined with adhesive waterproof tape respectively, and be fixed together, obturator is slowly put into well, until touch the water surface, with the water surface, be as the criterion, and then stop transferring while transferring to lower 1 meter of water layer, controlling on the ground igniting ignites, then obturator is proposed in well, carry out next operation, number of operations is depending on Underwell permeable length of tube and the depth of water, and every 1 meter to 2 meters depth of water next time swollen detonator is ignited once;
3, prune job
After the swollen quick-fried reparation of well completes, draw water immediately, so as the silt of bottom, oxide, permeable obstruction along with current clean out well.
Described swollen detonator comprises potassium nitrate 60%, charcoal powder 18%, water 22%, its preparation method is for to join potassium nitrate and water in iron or aluminium vessel, heat, until potassium nitrate dissolves the rear charcoal powder of pouring into rapidly completely, stir cooling after 3 minutes, dry in the shade, be ground into powder.
Described obturator comprises protection bucket, core cylinder, suspension ring, fixed head and caging bolt; described protection bucket upper end is fixedly installed suspension ring; bucket is uniform on wall arranges some air vents; described core cylinder is bottom sealing; the uncovered setting in upper end the hole arranging on barrel soleplate with protection are suitable, by fixed head and caging bolt, are spirally connected fixing.
Described ignition device comprises ignite wire and ignition part, and the upper end of wire is connected with power supply, and lower end is connected with ignition part.
Described ignition part is heating resistance wire.
The present invention relies on power supply that a kind of mine water of putting into is ignited with the swollen detonator of protective device; then produce the high temperature of strong expansion, pressure and nearly 900 ℃; thereby the scale, incrustation scale and the various obstruction that are attached to well tube wall and bottom are forced to come off; again by water pump along with current cleanings is discharged outside well, to reach the optimum efficiency of repairing well.On the protection bucket bucket wall of obturator of the present invention, the air vent of uniform setting can make expansion force evenly discharge, and has effectively avoided expansion force to concentrate the damage discharging well casing, has prosthetic appliance simple with the inventive method reparation well; rehabilitation cost is cheap, time saving and energy saving, simple operation; pollution-free; efficiency is high, effective, applied range of the present invention; at well depth 10-200 rice; in depth of water 2-50 rice, no matter well caliber size all can be used, and is suitable for applying in well compact district, rural area.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is that the master of obturator of the present invention looks half sectional view;
Fig. 2 is the upward view of Fig. 1.
