Description

A kind of wellbore tubular with step

Technical field

This utility model is related to inspection shaft field, more particularly, to a kind of wellbore tubular with step.

Background technology

At present, the matched wellbore tubular of existing municipal administration plastic inspection well base is all hollow spiral tube, is used Hollow spiral tube when settling occurs in ground, is acted on without anti-settling as wellbore tubular weight weight, to the bearing capacity of shaft bottom seat compared with Greatly.

And secondary electric smelting or sweat soldering are all needed in the larger product needed step of specification in pipe material inner wall, increased and apply Work operation and construction cost；

In addition circular configuration does not include big sewage well for part bore and cannot arrange step, exist cannot go into the well work or The problems such as difficulty of going into the well.

Existing electric power, telecommunications well are mainly square or rectangle, and matched wellbore tubular is all the square or rectangle frame of monolayer Frame, not only without anti-settling function, and single layer structure wall insufficient strength, it is larger to the bearing capacity of shaft bottom seat.

Utility model content

This utility model is to overcome at least one defect (deficiency) described in above-mentioned prior art, there is provided one kind can be reduced The wellbore tubular with step of construction cost.

To solve above-mentioned technical problem, the technical solution of the utility model is as follows：

A kind of wellbore tubular with step, including body and the step located at inboard wall of tube body, the body are single-wall corrugated pipe Body, the inner and outer wall of single-wall corrugated pipe body are concavo-convex alternate ripple struction, and step with single-wall corrugated pipe body is One-shot forming structure.

In such scheme, step is with the crest of the outer wall inward wall convex from single-wall corrugated pipe body as pedal.

In such scheme, the both sides of pedal are provided with V-type muscle.

In such scheme, the upper end and/or lower end of pedal are provided with V-type muscle.

In such scheme, the upper strata crest of pedal is provided with U-shaped recess.

In such scheme, the pedal is arranged on two relative faces of single-wall corrugated pipe inboard wall of tube body.

In such scheme, the pedal is arranged on two adjacent faces of single-wall corrugated pipe inboard wall of tube body.

In such scheme, the quantity that pedal is arranged on both faces is identical with position.

In such scheme, the quantity that pedal is arranged on both faces is identical, and position is staggered.

In such scheme, the single-wall corrugated pipe tubular body is square or rectangular configuration.

Compared with prior art, the beneficial effect of technical solutions of the utility model is：

(1) this utility model adopts single-wall corrugated pipe body as the agent structure of whole wellbore tubular, due to single wall ripple Pipe body is elastic construction, similar to spring, has bounce when ground occurs and settling, pit shaft when can be effectively reduced sedimentation Bearing capacity of the pipe to shaft bottom seat, can effectively improve the service life of system accessories.

And as the single-wall structure of single-wall corrugated pipe body is compared with hollow spiral tube, weight is lighter, more environmentally friendly.

(2) step of the present utility model and single-wall corrugated pipe body one-shot forming avoid hollow spiral tube need it is secondary The working procedure of welding step, has saved construction cost, and step directly by the use of crest as pedal, and step is not take up sky Between, applicable specification is more.

(3) single-wall corrugated pipe body of the present utility model adopts square or rectangular configuration, square structure or rectangular configuration with Circular configuration compares, and the square or rectangular configuration area of same specification is more than circular configuration, equal relative to existing hollow spiral tube Compared using circular configuration, this utility model can make whole pit shaft tube space bigger using square or rectangular configuration.

(4) this utility model is provided with V-type muscle in the both sides of pedal, also strengthen well for positioning while step position The longitudinal strength of bobbin.

(5) this utility model arranges U-shaped recess in the upper strata crest of pedal, for avoiding when workmen is upper and lower Layer stop of the crest to leg, constructs convenient.

Embodiment 1

As Figure 1-5, it is a kind of structural representation of the wellbore tubular specific embodiment with step of this utility model.Referring to Fig. 1-5, a kind of wellbore tubular with step of this specific embodiment specifically include body 1 and the step 2 located at 1 inwall of body, described Body 1 is single-wall corrugated pipe body, and for square, the inner and outer wall of single-wall corrugated pipe body is concavo-convex single-wall corrugated pipe body Alternate ripple struction, step 2 are one-shot forming structure with single-wall corrugated pipe body.

Wherein, step 2 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 3.The setting of V-type muscle 3 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 4.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 4, stop of the upper strata crest to leg when workmen can be avoided upper and lower is constructed 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 left side), the staggered arrangement array structure on next terraced (or the right) on the right.

In specific implementation process, the upper end and/or lower end of pedal are provided with V-type muscle, can further strengthen wellbore tubular Intensity.

When engineering construction is installed, placed after installing plastic inspection well base and arm tubing first, then will be using this In specific embodiment, wellbore tubular is inserted into shaft bottom seat socket, and the well lid on upper strata etc. is installed in connection, individual plastic inspection is completed The installation of well.

Step of the present utility model 2 and 1 one-shot forming of body, depending on pit shaft length of tube can be according to construction requirement.Can be extensive Suitable for rain dirt well, electric power telecommunications well, valve well, well, electric power telecommunications well, valve well etc..And step 2 of the present utility model is straight Connect by the use of crest as pedal, be not take up space, applicable specification is more.Single-wall corrugated pipe pipe structure similar to spring, Ground occurs having bounce during sedimentation, and bearing capacity of the wellbore tubular to shaft bottom seat when effectively can prevent from settling can be effectively improved The service life of system accessories.Single-wall structure is compared with hollow spiral tube, and weight is lighter, more environmentally friendly.Square wellbore tubular with it is same The circular wellbore tubular reference area of specification is bigger, structural strength while anti-settling supporting with square electric power, telecommunication inspection manhole More preferably.

The corresponding same or analogous part of same or analogous label；

Position relationship for the explanation of being for illustration only property described in accompanying drawing, it is impossible to be interpreted as the restriction to this patent；
