Abstract
The invention provides a method for dealing with clogging of a thin tube well. An air compressor, a winch, a pressure air pipe, galvanized steel pipes, seamless water outlet steel pipes and a grappling and fishing device are needed in the method. The method for dealing with clogging of the thin tube well mainly comprises the steps of water injection, galvanized steel pipe connection, connection ventilation and stone grabbing. According to the method, the structure is simple, operation is convenient, only a small number of workers are needed to complete the work, labor output is effectively lowered, and efficiency is improved at the same time. As is known in practical operation, clogging substances in a well with the depth of about 30 m can be discharged in about 8 h through the method, and compared with a common method, the clogging substances can be discharged more thoroughly.
Description
Technical field
The present invention relates to tubule well field, is a kind of method of repairing tubule well silting specifically.
Background technology
Wet well is adopted the largest source that water is existing drinking water, but existing wet well is because caliber is less, so easily produce the problem of silting while not using for a long time, the relevant treatment of tubule well silting bothers very much, once can not get processing timely, its silting can get more and more, and finally may cause wet well to be destroyed, and causes damage.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the method for repairing tubule well silting with a kind of is provided, solve existing tubule well and process the more difficult problem of silting.
The present invention solves the problems of the technologies described above by the following technical solutions:
Repair a method for tubule well silting, it will use following equipment: air compressor, hoist engine, pressure airduct, coating steel pipe, seamless water outlet steel pipe, grab the equipment of dragging for.
The present invention mainly realizes the reparation to tubule well silting by following steps:
1, water filling: first make its deposit soft to water filling in the tubule well of silting;
2, connect coating steel pipe: according to the degree of depth of deposit, connect coating steel pipe, the coating steel pipe of bottommost is made as 45 degree end faces, between coating steel pipe, by pipe collar, is connected, and by hoist engine, the coating steel pipe connecting is put into tubule well;
3, connect and ventilate: by pressure airduct, connect the top of air compressor machine and coating steel pipe, air compressor machine carries out air feed from small to large, and deposit is overflowed from well head along current;
4, capture stone: while running into larger stone or silting thing, the available equipment of dragging for of grabbing catches stone or silting thing again and operates.
The tubule well that surpasses 150mm for the mouth of pipe, can select the mode that adopts seamless steel pipe to coordinate: the side at coating steel pipe arranges seamless steel pipe simultaneously, and the bottom of coating steel pipe leads to the bottom of seamless steel pipe.
The present invention is simple in structure, easy to operate, in the process of work, only need a small amount of personnel to complete, effectively saved manpower output, improved efficiency simultaneously, known through actual operation, the well of 30 meters of left and right of the degree of depth adopts the present invention only to need can discharge silting about 8 hours, more thorough to the discharge of silting thing also more common method.
The specific embodiment
Embodiment 1
Somewhere a bite tubule well, 35 meters of well depths, diameter is 100mm, the silting time grows and silting place is positioned on the water surface, according to exploration, in silting thing, may contain the foreign material such as stone.
Adopt following steps to operate:
1, water filling: adopt water pump to pour water in the well of silting, the amount of injected water, for flooding silting thing, is soaked after a hour, and inner deposit becomes soft;
2, connect coating steel pipe: coating steel pipe is connected successively, and a joint coating steel pipe end of foot is made as 45 degree cross sections, and other coating steel pipe is connected by pipe collar, with hoist engine, coating steel pipe is put into well, connects coating steel pipe while putting;
3, connect and ventilate: after coating steel pipe end inserts soft deposit, at the top of coating steel pipe Bonding pressure airduct, the other end of pressure airduct is connected to air compressor, then opening air compressor blows, just initiation pressure, roughly at 0.2MPa, increases pressure, gradually along with the increase of ventilation time, deposit and water soft in well flow out along the gap between coating steel pipe outside and the borehole wall, continue coating steel pipe to insert when ventilating downwards;
4, capture stone: when running into stone or other foreign material, coating steel pipe can not continue down deep time, with hoist engine, coating steel pipe is taken out, and adopt and to grab the equipment of dragging for and put into thin well stone or foreign material are caught, then continue to adopt coating steel pipe blow and arrange silt.
As calculated, this well completes removing total time from starting working to is 8.2 hours, and the mode that adopts two staff to cooperatively interact in the process of work completes.
Embodiment 2
Somewhere a bite tubule well, 35 meters of well depths, diameter is 100mm, silting place is positioned at underwater, according to exploration, in silting thing, may contain the foreign material such as stone.
Adopt following steps to operate:
1, connect coating steel pipe: coating steel pipe is connected successively, and a joint coating steel pipe end of foot is made as 45 degree cross sections, and other coating steel pipe is connected by pipe collar, with hoist engine, coating steel pipe is put into well, connects coating steel pipe while putting;
2, connect and ventilate: after coating steel pipe end inserts soft deposit, at the top of coating steel pipe Bonding pressure airduct, the other end of pressure airduct is connected to air compressor, then opening air compressor blows, just initiation pressure, roughly at 0.2MPa, increases pressure, gradually along with the increase of ventilation time, deposit and water soft in well flow out along the gap between coating steel pipe outside and the borehole wall, continue coating steel pipe to insert when ventilating downwards;
3, capture stone: when running into stone or other foreign material, coating steel pipe can not continue down deep time, with hoist engine, coating steel pipe is taken out, and adopt and to grab the equipment of dragging for and put into thin well stone or foreign material are caught, then continue to adopt coating steel pipe blow and arrange silt.
As calculated, this well completes removing total time from starting working to is 7.3 hours, and the mode that adopts two staff to cooperatively interact in the process of work completes.
Embodiment 3
Somewhere a bite tubule well, 35 meters of well depths, diameter is 180mm, the silting time grows and silting place is positioned on the water surface, according to exploration, in silting thing, may contain the foreign material such as stone.
Adopt following steps to operate:
1, water filling: adopt water pump to pour water in the well of silting, the amount of injected water, for flooding silting thing, is soaked after a hour, and inner deposit becomes soft;
