Abstract
The utility model relates to a polyvinyl chloride well pipe comprising a plurality of real wall pipes, and a plurality of screen pipes. The head end and the back end of each real wall pipe respectively have a matching screw-shaped turnbuckle, and the head end and the back end of each real wall pipe are orderly screwed by the screw-shaped turnbuckle. The head end and the back end of each screen pipe respectively have a matching screw-shaped turnbuckle, and the head end and the back end of each screen pipe are orderly screwed by the screw-shaped turnbuckle. The back end of the lowermost real wall pipe is screwed to the head end of the uppermost screen pipe by the screw-shaped turnbuckle. The polyvinyl chloride well pipe of the utility model has advantages of strong tensile property, high integral strength, low cost and high efficiency of construction, and the breakage rate of well pipes is reduced. The water seepage bores on the screen pipe consist of narrow groove bores uniformly distributed in a ring direction along the pipe wall to sufficiently ensure the own rate of porosity of the screen pipe, sands and rocks are not easily enter, the water resistance is small, and the damage of water is few. The polyvinyl chloride well pipe can bear a high intensity compression, the service life is long, and the polyvinyl chloride well pipe is suitable for pumping wells and water wells.
Description
Technical field
The utility model relates to well casing, belongs to the mining of groundwater field.
Background technology
People will be lowered to well casing in motor-pumped well when well-digging, well casing is made up of filter pipe and solid wall pipe, and filter pipe is the well casing of a kind of surface band circular hole, and solid wall pipe is a kind of surface well casing not with holes.Filter pipe can have more piece, is installed in underground aquifer, allows underground water penetrate into from circular hole in the filter pipe, by the underground water in the water pump extraction filter pipe, underground water is drawn into ground again.Solid wall pipe has more piece, be contained in the top of filter pipe, extend to well head place, ground always, each saves between the filter pipe, between filter pipe and the solid wall pipe, respectively save between the solid wall pipe and all be connected by pipe collar, pipe collar is a metal tight loop, be fastened on the joining place of adjacent two joint well casings by welding, well casing is pipe of cement or cast iron pipe, and weight is big, connects each well casing with the mode of welding, waste time and energy, construction speed is slow, and construction costs height, weld are subjected to the corrosion of down-hole tide vapour easily, easily get rusty, reduce application life.Another problem that existing well casing exists is, the hole that is used on the filter pipe seep water is a circular port, is similar to circular cobble and usually have some in the underground aquifer, enters easily when drawing water in the filter pipe, and hole plug maybe will seep water.So the external surface of existing filter pipe also is shaped on the axial pillow bar of projection, catch net is equipped with in the outside of pillow bar, causes the complex structure of whole filter pipe, and drainage efficient is not high.
Summary of the invention
The purpose of this utility model provides a polyvinyl chloride well casing, its easy construction, firm, time saving and energy saving, infiltration hole is installed is difficult for blocked, drainage efficient height.
For achieving the above object, the utility model is by the following technical solutions:
A kind of polyvinyl chloride well casing, comprise solid wall pipe and filter pipe, solid wall pipe has more piece, filter pipe has more piece, the infiltration hole is arranged on the filter pipe, solid wall pipe is contained in the top of filter pipe, it is characterized in that: the head end of described every joint solid wall pipe and tail end have the screw thread screw thread that matches respectively, each head end and tail end that saves solid wall pipe is screwed onto together by the screw thread screw thread successively, the head end of described every joint filter pipe and tail end have the screw thread screw thread that matches respectively, each head end and tail end that saves filter pipe is screwed onto together by the screw thread screw thread successively, and the tail end of next joint solid wall pipe is screwed onto by the screw thread screw thread with the head end of going up most a joint filter pipe.
There are many rows in infiltration hole on described every joint filter pipe, and every row hole of seeping water is made of a plurality of narrow slotted eyes that circumferentially distribute along the filter pipe tube wall.
Described each row's infiltration hole is axially evenly distributed along filter pipe.
The narrow slotted eye that described every row seeps water in the hole circumferentially evenly distributes along the filter pipe tube wall.
The material of described solid wall pipe and filter pipe is a polyvinyl chloride.
The utility model has the advantages that adopt screw thread screw thread head and the tail to connect and compose successively between each pipe joint, screw thread pitch is big, tensile property is strong, and the bulk strength height has reduced the breakage rate of well casing greatly, reduced construction costs, the efficiency of construction height is applicable to the motor-pumped well well.
The material of well casing is a polyvinyl chloride, corrosion-resistant, low price, non-scaling, does not grow algae, not polluted water, in light weight, convenient transportation, can reduce freight, the labour intensity when reducing carrying and installation.Installation saves time, laborsaving, saving of labor, and erection procedure is easy, quick, without other stubborn button instrument, directly wears button with hand, can manage down smoothly by deadweight.
Infiltration hole on the filter pipe is by constituting along the equally distributed narrow slotted eye of tube wall hoop; fully guaranteed the porosity of filter pipe self, overcome the weakness that circular port advances sandstone easily, without catch net; can play filter sand masonry usefulness equally, the inside and outside smooth surface of tube wall, water resistance is little, damage by water is few.The narrow slotted eye of hoop can bear very big circumference stress, can bear the high strength extruding that the down-hole backfill causes the filter pipe outer wall.Long service life.
