Abstract
The invention provides a steel framework plastic inspection shaft and relates to the technical field of inspection shafts. The steel framework plastic inspection shaft comprises a steel bar frame I, a second steel bar frame II, a pipe connector and a shaft. A well chamber of the shaft is formed by welding the steel bar frame I and the second steel bar frame II which are high in strength, the inner and outer surfaces of a steel pipe frame are fully wrapped by polyethylene raw materials. The shaft is connected with the pipe connector, the pipe diameter of the shaft is 315-1000mm, and the pipe diameter of the pipe connector is 200-3000mm. The steel framework plastic inspection shaft is high in strength, good in corrosion resistance and airtight effect, light in weight, convenient and quick to construct, low in cost and long in service life.
Description
Technical field:
The present invention relates to manhole technical field, be specifically related to a kind of plastic inspection well with steel skeleton.
Background technology:
Manhole is commonly called as " inspection shaft ", is generally located on drainage pipe intersection, turning, caliber or gradient change place, drop place and straight line pipeline section and locates at a certain distance, be convenient to make regular check on, the draining ancillary structure of clean and dredging pipeline.In drainage and exhaust system, continue to use the brick of traditional form and concreting manhole, technique falls behind always, and efficiency of construction is low, easily produces seepage, leakage, and perishable, and application life is short.The Ministry of Construction of the People's Republic of China, MOC's [218] number file in 2004 is announced, and clearly provides against use clay solid brick; Nation-building cause Eleventh Five-Year Plan technology bulletin plastic conduit preferentially adopts in plastic inspection well publicity clearly to be stipulated, eliminates brick well.But the current plastic inspection well using in engineering, mostly is injection mo(u)lding manhole, and bore is little, and structural strength is low, can not meet town road, the draining blowdown pipe networks such as industrial enterprise supporting; Especially heavy caliber field, the plastic inspection well that useful hollow spiral tube material is processed in the market, but its ring stiffness can not meet design and construction needs, on market, is substantially still using brick manhole.Efficiency is low, at aspect wretched insufficiencies such as antiseep, anticorrosion, antidetonations, does not also meet national industrial policies requirement simultaneously.
Summary of the invention:
The object of this invention is to provide a kind of plastic inspection well with steel skeleton, its intensity is high, anticorrosive good, lightweight with obturation effect, and convenient and quick construction is with low cost, long service life.
In order to solve the existing problem of background technology, the present invention adopts following technical scheme: it comprises steel bar framework one, steel bar framework two, conduit coupling, pit shaft; The well chamber of pit shaft consists of high-intensity steel bar framework one and steel bar framework two welding, and steel framework surfaces externally and internally is fully wrapped up by polyethylene raw material; Pit shaft is connected with conduit coupling, and the caliber of pit shaft is 315～1000mm, and the caliber of conduit coupling is 200～3000mm.
The present invention has following beneficial effect:
One, owing to adopting steel as main supporting construction, increased the bulk strength of manhole, can be embedded in the darker location of the ground degree of depth, and overall weight has been light; Inside and outside wall is polythene material, and inner wall smooth is smooth, efficient draining, and dirt is difficult for being detained, and has reduced the possibility of stopping up, and long service life;
Two, because all parts of plastics adopt PE material, avoided the seepage possibility of split socket joint, whole tightness is strong, anticorrosive, environmental protection leakproof, safe and reliable;
Three, because overall weight is light, simple in structure, site operation simple and fast, integrated cost is lower.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
The specific embodiment:
Referring to Fig. 1-Fig. 2, this specific embodiment adopts following technical scheme: it comprises steel bar framework 1, steel bar framework 22, conduit coupling 3, pit shaft 4; The well chamber of pit shaft 4 consists of high-intensity steel bar framework 1 and steel bar framework 22 welding, and steel framework surfaces externally and internally is fully wrapped up by polyethylene raw material; Pit shaft 4 is connected with conduit coupling 3, and the caliber of pit shaft 4 is 315～1000mm, and the caliber of conduit coupling 3 is 200～3000mm.
This specific embodiment has following beneficial effect:
One, owing to adopting steel as main supporting construction, increased the bulk strength of manhole, can be embedded in the darker location of the ground degree of depth, and overall weight has been light; Inside and outside wall is polythene material, and inner wall smooth is smooth, efficient draining, and dirt is difficult for being detained, and has reduced the possibility of stopping up, and long service life;
Two, because all parts of plastics adopt PE material, avoided the seepage possibility of split socket joint, whole tightness is strong, anticorrosive, environmental protection leakproof, safe and reliable;
Three, because overall weight is light, simple in structure, site operation simple and fast, integrated cost is lower.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
