Abstract
The utility model discloses a circle double-wall casing pipe, which comprises a casing pipe and is characterized in that a wall of the casing pipe is provided with filtrating orifices, the casing pipe is provided with a liner tube with the filtrating orifices, a hollow cavity between two walls of the casing pipe and the liner tube is provided with reinforced ribs with longitudinal connecting holes inward. The upper end of the casing pipe is provided with a circle slot, the lower end of the casing pipe is provided with a circle plug matching the circle slot of the upper end of the casing pipe, and the middle portion is provided with a circle hollow double-wall pipe formed by the reinforced ribs, which not only reduces the weight of the casing pipe, but also increases the compression strength of the casing wall. Since each single pipe is short and is formed by plastic on time, the utility model achieves low cost, long service life, high output ratio and convenient transportation and installment, but also is not rusted and clogged and does not pollute the water quality, which is a novel unique motor well pipe production.
Description
Technical field
The utility model relates to a kind of wall casing, more particularly relates to a kind of annular double-walled wall casing, belongs to a kind of 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 wall 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 wall casing, it is characterized in that the tube wall of wall casing is provided with treatment hole, also is provided with the bushing pipe of band treatment hole in the wall casing; Inner chamber between wall casing and bushing pipe double-walled is connected with reinforcing rib, and connecting hole is longitudinally arranged in the reinforcing rib; There is annular slot the upper end of wall casing, and there is the annular plug that cooperates with upper end annular slot the lower end of wall casing.
Owing to adopted such scheme, make wall casing form tube wall and have the annular hollow 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 borehole wall tubing 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 wall casing.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
In Fig. 1-2, the tube wall of wall casing 1 has treatment hole, and treatment hole is 20*8mm
2Oblong aperture, also have a bushing pipe 4 with same treatment hole in the inboard of wall casing 1.Wall casing 1 is made annular with bushing pipe 4 usefulness modified poly ethylene plastics by the disposable one injection moulding of mould, and the length of the every joint of single body is 50mm.Surround the slot 2 of an annular by wall casing 1 and bushing pipe 4 on the top of wall casing 1, annular slot below 2 wall casing 1 and bushing pipe 4 between the inner chamber 7 that makes wall casing 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.Wall casing 1 has an annular plug 8 of pegging graft with wall casing top annular slot 2 with the lower end of bushing pipe 4.
During installation, with one group of 20 annular wall casing 1, by the annular plug 8 of wall casing 1 lower end and the annular jack 2 head and the tail grafting successively of another wall 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, make in the connecting hole 3 on wall casing 1 reinforcing rib and be equipped with connecting reinforcement, the two ends of connecting reinforcement screw movable joint shape nut then, at this moment promptly the wall casing 1 of one group of 20 annular is concatenated into a body, forms the long tube of a band pore 6.With the long tube of a plurality of serial connections, the long tube movable joint that is concatenated into a body by movable joint shape nut and another is connected, 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 easy to characteristics, also can be widely used in ventilation, sewerage treatment, communication cable conduit and the bridges and culverts lock discharge pipe line.
