Abstract
The utility model discloses a ring-type double-wall spigot and socket casing pipe. A liner pipe is arranged in a casing pipe, reinforcing ribs are arranged between the casing pipe and the liner pipe, a group of reinforcing ribs are provided with longitudinal connecting holes, the upper end of the casing pipe is provided with an annular jack, and the lower end of the casing pipe is provided with an annular plug, and the annular shape of the annular plug is matched with the annular shape of the annular jack on the upper end of the casing pipe. The middle of the casing pipe is provided with an annular hollow double-wall pipe which is composed of the reinforcing ribs, so the weight of the casing pipe is lightened as well as pressure resisting intensity is increased. Because each segment of a single pipe body is shorter and plastic is shaped in one step, the utility model has the advantages of low cost, no rusting blockage, no pollution to water quality, long service life, high water yielding rate, and convenient transportation and installation.
Description
The utility model relates to a kind of wall casing, more particularly relates to a kind of annular double-walled spigot-and-socket wall casing, belongs to a kind of improvement of Electrical Well wall casing.
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.
The purpose of this utility model provides a kind of annular double-walled spigot-and-socket 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 easy for installation.
The purpose of this utility model is achieved in that it comprises wall casing, is characterized in that: wall casing is a ring-type, and a bushing pipe is arranged in wall casing, is provided with reinforcing rib between wall casing and bushing pipe, on one group of reinforcing rib connecting hole is longitudinally arranged; There is the annular jack that is surrounded by wall casing and bushing pipe the upper end of wall casing; The annular plug that the lower end of wall casing has the annular that connected into by wall casing and bushing pipe and wall casing upper end to cooperate at annular jack.
Owing to adopted such scheme, make wall casing form the middle double-wall pipe that the annular hollow of reinforcing rib is arranged, 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 250mm, and adopts injection molded of plastics.Have that non-corrosive blocks, cost is low, long service life, not polluted water, characteristics that water rate is high, not only made an appointment with a large amount of steel, transportation and install very conveniently is a kind of novelty and the borehole wall tubing that shows unique characteristics.
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 spigot-and-socket wall casing.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the junction plate constructional drawing.
In Fig. 1-3, wall casing is once made annular with the modified poly ethylene plastics by mold injection, also has a bushing pipe 4 in the inboard of wall casing 1.Surround the jack 2 of an annular by wall casing 1 and bushing pipe 4 on the top of wall casing, annular jack below 2 wall casing 1 and bushing pipe 4 between be useful on and save the modified poly ethylene plastic material, make the light cavity 7 of borehole wall body body simultaneously, in cavity 7, be provided with nine vertical equally distributed reinforcing ribs 5.Have connecting hole 3 longitudinally on three of one group of triangular arranged reinforcing ribs 5 therein.4mm is hanged down on the last plane of last plane and other reinforcing rib of the reinforcing rib 5 of band connecting hole 3, behind the junction plate 9 of the thick 4mm of insertion and the upper end of other reinforcing rib on a horizontal plane; On the wall casing 1 of reinforcing rib 5 upper ends of being with connecting hole 3, be respectively equipped with the horizontal jack of placing junction plate 9.Wall casing 1 has a ladder platform respectively with the lower end of bushing pipe 4, and wall casing 1 is connected in ladder platform lower end with bushing pipe 4, constitutes the annular plug 8 of pegging graft with annular jack 2 another wall casing upper end a annular.
During installation, with one group of 20 annular wall casing, by the annular plug 8 of wall casing lower end and the annular jack 2 head and the tail grafting successively of another wall casing upper end; Align the vertical connecting hole 3 on the reinforcing rib 5.To place with the junction plate 9 of connecting hole 10 again head and the tail two ends the annular borehole wall on horizontal jack.Three diameters of TBE (threaded both ends) are the 8mm connecting reinforcement, be inserted in respectively in three connecting holes 3 on the wall casing reinforcing rib 5, make in the connecting hole on the wall casing reinforcing rib and be equipped with connecting reinforcement, the tight top nut in the two ends of connecting reinforcement then, at this moment promptly the wall casing 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, can connect into the random length that needs by another connecting hole 10 usefulness bolts on the junction plate 9.With around the bushing pipe 4 vertical rectangular treatment hole is arranged at wall casing 1, the width of treatment hole is 2mm, promptly makes the filter pipe of motor-pumped well drainage layer, can save the gauze on the filter pipe, has saved material, also can get out treatment hole at a certain distance on wall casing.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.
