Abstract
The present utility model discloses a ring-shaped double-walled well pipe comprising an outer pipe. The ring shaped double-walled well pipe is characterized in that the wall of the outer pipe has water straining holes; a group of reinforcing rods are connected in an inner chamber between the outer pipe and a liner pipe, and there are longitudinal connection holes in the reinforcing rods; an upperend of the outer pipe has a ring-shaped slot and a lower end of the outer pipe is provided with a ring-shaped plug cooperating with the ring-shaped slot of the upper end. Therefore, a ring-shaped double-walled pipe of which the wall has water straining holes and the middle part is connected with reinforcing rods can be formed, the weight of the pipe body can be reduced and the compression strengthcan be increased, the ring-shaped double-walled well pipe has characteristics of rustless block, low cost, long service life, pollution-free of water quality and high yielding water rate, because thelength of each section of a simple pipe body is very short, usually within 50mm and a one-time injection shaping method is adopted, a great amount of steels can be saved, and the installation and transportation of the pipes are very convenient, above all, the present utility model provides a product of a ring shaped double-walled well pipe which is novel and characteristic.
Description
Technical field
The utility model relates to a kind of well casing, more particularly relates to a kind of annular double-walled well casing, belongs to the improvement of Electrical Well wall casing.
Background technology
At present, the wall casing of Electrical Well adopts seamed metal tube or the reinforcing cage made by steel plate to twine fiber tube usually, these two kinds of wall casings consume that steel are many, cost is high, corrosion-resistant, application life is short and the easy-to-rust obstruction, had a strong impact on water quality and water rate, and reinforcing cage to twine a borehole wall compressive strength low.Also useful concrete pipe is made the borehole wall, but weight is big, transportation and inconvenience is installed, and now few people use.
Summary of the invention
The purpose of this utility model provides a kind of annular double-walled well casing, and not only long service life is corrosion-resistant for it, non-corrosive blocks, not polluted water, water rate height, and save steel, in light weight, compressive strength is high, transportation and install very convenient.
The purpose of this utility model is achieved in that it includes outer tube, it is characterized in that the tube wall of outer tube is furnished with treatment hole, also is provided with the bushing pipe of band treatment hole in outer tube; Inner chamber between outer tube and bushing pipe is connected with one group of reinforcing rib, and connecting hole is longitudinally arranged in the reinforcing rib; There is annular slot the upper end of outer tube, and there is the annular plug of pegging graft and cooperating with upper end annular slot the lower end of outer tube.
Owing to adopted such scheme, make annular double-walled well casing form tube wall and have the annular double-wall pipe that treatment hole, centre are connected with reinforcing rib, both alleviated the weight of borehole wall body, increased compressive strength again, because the length of the every joint of single body is short usually in 50mm, and adopt injection molded of plastics, have that non-corrosive blocks, cost is low, long service life, not polluted water, characteristics that water rate is high, a large amount of steel have not only been saved, and transportation and install very conveniently, be a kind of novelty and the annular double-walled well casing product that shows unique characteristics.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the plan structure figure of the utility model annular double-walled well casing.
Fig. 2 is that the A-A of Fig. 1 is to view.
The specific embodiment
In Fig. 1-2, the tube wall of outer tube 1 has equally distributed treatment hole, and treatment hole is 20*8mm
2Oblong aperture, also have a bushing pipe 4 with the belt transect treatment hole in the inboard of outer tube 1.Outer tube 1 and bushing pipe 4 usefulness modified poly ethylene plastics are made the ring pipe of one by the disposable injection moulding of mould, and the every joint length of single body is 50mm.Surround the slot 2 of an annular by outer tube 1 and bushing pipe 4 on the top of outer tube 1, annular slot below 2 outer tube 1 and bushing pipe 4 between the inner chamber 7 that makes outer tube 1 body light is arranged, in inner chamber 7, be provided with 30 vertical equally distributed reinforcing ribs 5.On three of one group of triangular arranged reinforcing ribs 5 connecting hole 3 is longitudinally arranged therein.Outer tube 1 has an annular plug 8 of pegging graft with outer tube top annular slot 2 with the lower end of bushing pipe 4.
During installation, with one group of 20 annular double-walled well casing, by the annular plug 8 of well casing lower end and the annular jack 2 head and the tail grafting successively of another well casing upper end; Vertical connecting hole 3 on the alignment reinforcing rib 5.Diameter is that three reinforcing bars of 12mm, TBE (threaded both ends) are inserted in respectively in three connecting holes 3 on the wall casing reinforcing rib 5, be equipped with connecting reinforcement in the connecting hole 3 on the annular double-walled well casing reinforcing rib, the two ends of connecting reinforcement screw nut then, at this moment promptly one group 20 annular double-walled well casings are concatenated into a body, form the long tube of a band treatment hole 6.With the long tube of a plurality of serial connections, the long tube that is concatenated into a body by nut and another is connected again, to connecting into the random length that needs.
Since the utlity model has stronger resistance to compression, shock resistance, corrosion-resistant, anti-aging, easy to connect firm, and installation is executed The worker is easy to characteristics, also can be widely used in ventilation, sewage disposal, communication cable conduit and the bridges and culverts lock discharge pipe line.
