Embodiment 1
As Figure 1-3, it is a kind of structural representation of the wellbore tubular specific embodiment with bellmouth and step of this utility model
Figure.Referring to Fig. 1-3, a kind of wellbore tubular with bellmouth and step of this specific embodiment specifically includes body 1 and located at 1 inwall of body
Step 3, the body 1 be single-wall corrugated pipe body, single-wall corrugated pipe body one end is provided with bellmouth 2, single-wall corrugated pipe body
Inside is square, and the inner and outer wall of single-wall corrugated pipe body is concavo-convex alternate ripple struction, step 3, single-wall corrugated pipe
Body and bellmouth 2 are one-shot forming structure.
Wherein, step 3 is with the crest of the outer wall inward wall convex from single-wall corrugated pipe body as pedal.
In specific implementation process, step of the work progress to workmen for convenience is positioned, the both sides of pedal
It is provided with V-type muscle 4.The setting of V-type muscle 4 is not only able to position step, also enhances the longitudinal strength of wellbore tubular.
In specific implementation process, the upper strata crest of pedal is provided with U-shaped recess 5.In this specific embodiment, due to direct
Using the ripple of convex as pedal, also there is ripple struction in pedal up and down, therefore, U-shaped recess is set on the upper strata crest of pedal
5, stop of the upper strata crest to leg when workmen can be avoided upper and lower is constructed convenient.Further, can with
U-shaped recess is set on the upper strata crest and lower floor's crest of pedal, lower floor's crest is to lower limb when further avoiding workmen upper and lower
The stop in portion, construction are more convenient.
In specific implementation process, pedal can be arranged on two relative faces of single-wall corrugated pipe inboard wall of tube body.For big
Specification wellbore tubular, it is also possible to which pedal is arranged on into adjacent two face.Pedal is arranged on the quantity in two faces and position can be identical,
A ladder is gone up alternatively on the left side（Or the left side）, next ladder is on the right（Or the right）Staggered arrangement array structure.
In specific implementation process, the upper end and/or lower end of pedal are provided with V-type muscle 4, can further strengthen wellbore tubular
Intensity.Further, V-type muscle 4 can run through whole body 1.
When engineering construction is installed, placed after installing plastic inspection well base and arm tubing first, when shaft bottom seat connects
Interface portion is bellmouth, and during for supporting deeper plastic inspection well, first the supporting cushion rubber in one end by wellbore tubular without bellmouth is inserted
Enter to shaft bottom seat socket, then by multiple wellbore tubulars successively socket joint connection composition pit shaft part, reconnect and upper strata accessory is installed（Such as
Pit shaft lid etc.）, complete the installation of individual plastic inspection shaft.
When seat connection oral area in shaft bottom is socket, the one end with bellmouth can be connected with shaft bottom seat socket joint, upper end matching gel
Circle connection upper strata accessory.
Step of the present utility model 3, body 1, bellmouth one-shot forming, it is to avoid the working procedure of secondary welding, save
Construction cost, depending on pit shaft length of tube can be according to construction requirement.Be widely portable to rain dirt well, electric power telecommunications well, valve well,
Well, electric power telecommunications well, valve well etc..And step of the present utility model 3 is not take up space directly by the use of crest as pedal,
Applicable specification is more.Single-wall corrugated pipe pipe structure has bounce when ground occurs and settling similar to spring, can be effective
Bearing capacity of the wellbore tubular to shaft bottom seat when preventing from settling, can effectively improve the service life of system accessories.Single-wall structure is with
Empty wall winding tube compares, and weight is lighter, more environmentally friendly.Square wellbore tubular is bigger with the circular wellbore tubular reference area of same specification, with
While the supporting anti-settling of square electric power, telecommunication inspection manhole, structural strength is more preferable.
