The drive well which is also called Abyssinian is known to people for a long time. Its design consists of boring bar which has small diameter, and boring head which is equipped with the filter.
Instruction
1. To make Abyssinian well, it is necessary to chuck in boring bar the necessary depth. If it is necessary, it can also be increased. The well is ready after the boring head passes water-bearing stratum. The filter with drill serve as water receiving part, and boring column — water lifting and casing pipe. So, the well is made and it is necessary only to make registration of land part.
2. Quite simple device of well does this design attractive. However not everything is as simple as it would be desirable. The Abyssinian well can be arranged only in soft breed which does not support galechnik. The water-bearing stratum has to have depth about 7 meters, as a last resort – to 12 meters.
3. If there are pebble inclusions, then it is impossible to execute drive drilling by column of small diameter. Also It should be noted that such column on length more than 7 meters has insufficient stability on compression. When swamping it will be bent, spring, leave from vertical aside. For increase in diameter of boring bar it is necessary to use too powerful poppet. By own efforts this business cannot be executed. It is necessary to involve the specialized equipment.
4. The Abyssinian well can quite just be arranged. Also it has good performance – about one and a half buckets a minute. If it will be not enough, then it is possible to be engaged in the device of one more such well.
5. The working head of Abyssinian well has massive steel cone. Over it the water receiving site which represents pipe of a little smaller diameter with windows which have protection in the form of metal grid filter is welded. It is necessary to screw the main pipe with the ball valve in the lower part on the filter.
6. To make such well it is necessary to dig the mine 0.8 x 0.8 x 1 meters. The filter has to be rigidly mounted with pipe. Cargo up to 30 kilograms which is freely moved up and down pipe is surely got on pipe. It is necessary to recede from the filter 1 meter and to fix steel collar - pile block. A little above it make installation of the second collar with two blocks. The pipe with the filter, the valve and tip has to be established in the center of the prepared mine. After installation it needs to be filled up with soil. Soil should be condensed around the hung-out pipe. It is so possible to provide its steady vertical position.
