Description
Technical field
The present invention relates to no-excavation construction method field, the dilatory pipe of specifically a kind of spheroidal graphite cast-iron and its construction method.
Background technique
Because ductile iron pipe has, intensity is big, corrosion resistance is strong, rigidity is similar to the excellent properties such as steel pipe, extensively
It is general to be applied on industrial, civilian waterline.
When ductile iron pipeline carries out non-excavating construction using trombone slide method, length of pipeline is differed from tens meters to hundreds of meters,
It needs to connect into the disposable whole pulling construction of a pipeline progress, therefore pipeline and soil during pulling by tubing one by one
Very big frictional force can be generated between earth, due to being location that is poor for some soil properties, being not easy pore-forming, need to use biggish pulling force
Tubing could be pulled, since ductile iron pipe is connected using bell and spigot frame, pipeline disconnection is easy to appear in heave,
The construction of pipeline engineering may cause and seriously affect.During buried crossing construction, entering for pipeline and is pierced by ground at location
There are the deformations of certain angle for face section, therefore again such that quality problems occur for the pipeline at this.So common ductile iron pipe
Road is difficult with trombone slide method and carries out non-excavating construction.
Summary of the invention
The purpose of the present invention is to provide a kind of dilatory pipe of spheroidal graphite cast-iron and its construction methods, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the invention provides the following technical scheme:
A kind of dilatory pipe of spheroidal graphite cast-iron, is SIA-Wb interface, further includes accepting socket, PE set and steel bushing, on the undertaking socket
It is provided with protrusion part, the dilatory pipe of several spheroidal graphite cast-iron is connected by PE set, steel bushing and protrusion split-phase, the PE set and steel
It is socketed on undertaking spigot, and is heated.
As a further solution of the present invention: carrying out the tension after socket joint connection using SIA-Wb interface ductile iron pipeline
Power, can satisfy the pulling tension requirements of dilatory pipe, therefore ductile iron pipeline is in non-digging pipe installation, especially with dragging
Trombone slide method promoted and applied in terms of non-excavating construction.
A kind of spheroidal graphite cast-iron drag pipe construction method, the specific steps are as follows:
Step S1, socket joint connection will be carried out by ductile iron pipe two-by-two；
Step S2, socket is accepted in every connection together, and upper pyrocondensation PE set is just covered on interface；
Step S3, PE set is heated with heat sources such as grilled guns, PE set is made to shrink and tightly wrap undertaking socket；Wherein PE covers
Effect are as follows: socket and pipeline external sundries are accepted in isolation, make to accept socket in dragging process, cleaning is kept after dragging,
It not only keeps clean and tidy and is able to extend service life；
Step S4, after the installation for completing PE set, then the protrusion part being provided on external bellmouth is covered to PE with steel bushing and carries out ring packet,
And with iron wire banding, is scratched when dilatory by the particulate matter in hole with preventing PE from covering, improve the service performance of the device；
Step S5, step S1 to step S4 is repeated, then third ball graphite cast iron pipe is held with the ductile iron pipe connected
Connection is inserted, until being all installed.
Spheroidal graphite cast-iron as mentioned draws utilization of pipe during non-excavating construction.
Compared with prior art, the beneficial effects of the present invention are: the present invention uses the ductile iron pipe conduct of SIA-Wb interface
The main material of dilatory pipe, drag pipe construction technique is combined with the excellent properties of ductile iron pipe itself, improves pipeline
Safe operating life, improves the corrosion resistance and mechanical property of dilatory pipe, and when installation is affected by environment small, can be in difference
It is installed under environment, it is simple and fast, a large amount of artificial, time, space cost can be saved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that two ball graphite cast iron pipes are carried out to socket joint connection in step 1.
Fig. 2 is Step 2: in the structural schematic diagram of the position cladding PE set of socket joint connection in three.
Fig. 3 is to coat the structural schematic diagram of steel bushing in bellmouth prominent position in step 4.
In figure: 1-PE set, 2- steel bushing, 3- protrude part.
