Description
Technical field
It the utility model is related to the interior insertion technical field of Gas Pipe, more particularly to the interpolation core pipe for large diameter pipeline
Protective folder.
Background technology
The interior insertion construction technology of Gas Pipe, be based on not destroying earth construction, and merged no-dig technique poling technology,
The comprehensive construction work that gas pipeline transmission ＆ distribution technology, the construction technology of polyethylene gas pipe and detection technologies for underground pipes are integrated
Skill.Constructed using poling, can effectively lower the discharge of the noise of job site, airborne dust and sewage, transformed with conventional pipelines
Technology is compared, and significantly reduces the influence to surrounding environment of constructing.
But in practice of construction, in order to ensure construction quality it is necessary to ensure that the anticorrosive coat of core pipe is complete；In insertion process
In, to reduce the contact between old inside pipe wall and core tube wall.
Therefore, it is necessary to during insertion can isolate the larger old pipe of bore with core pipe for this Technology design is a kind of
Instrument, to ensure construction quality.
Utility model content
In view of the drawbacks described above of prior art, the utility model provides the interpolation core pipe protection for large diameter pipeline
Folder, the first purpose of realization is to provide a kind of special core pipe protective folder for the interior insertion technology of Gas Pipe, it would be desirable to insertion
Core pipe is isolated with the tube wall of old pipeline during insertion, and core pipe anticorrosive coat is complete after the completion of ensureing construction.
To achieve the above object, the utility model discloses the interpolation core pipe protective folder for large diameter pipeline, including branch
Frame, the length of the support and the internal diameter of large diameter pipeline match, and the both sides in the support centre position are respectively equipped with the first pipe
Hoop, the second pipe collar；
The axis of first pipe collar and the diameter parallel of the second pipe collar, and it is vertical with the length direction of the support；Institute
The diameter for stating the second pipe collar is more than first pipe collar.
Guide feet is equipped with the outside of the both ends of the support, and second pipe collar, all the guide feet is corresponding
The madial wall of the large diameter pipeline is set.
Preferably, all it is equipped with roller in the guide feet.
Preferably, first pipe collar, second pipe collar include fixed part and removable section, first pipe
Hoop, the fixed part of second pipe collar are fixedly connected with the support, first pipe collar, second pipe collar
Removable section removably removably connects with the corresponding fixed part.
Preferably, first pipe collar, the fixed part of second pipe collar and the removable section use
Bolt connection.
Preferably, the fixed part of first pipe collar, second pipe collar is with welding manner and the support
It is fixedly connected.
The beneficial effects of the utility model：
The core pipe that the multiple guide feets and first, second pipe collar that the utility model nationality is fixed by relative position insert needs
Separated with large diameter pipeline, ensure that work progress core pipe and large diameter pipeline will not collide with this, after the completion of construction
Core pipe anticorrosive coat is complete.
Design, concrete structure and caused technique effect of the present utility model are made furtherly below with reference to accompanying drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Brief description of the drawings
Fig. 1 shows the structural representation of the embodiment of the utility model one.

The diameter parallel of the axis of first pipe collar 2 and the second pipe collar 3, and it is vertical with the length direction of support 1；Second pipe collar
3 diameter is more than the first pipe collar 2.
The both ends of support 1, and the outside of the second pipe collar 3 are equipped with guide feet 4, and whole guide feets 4 correspond to large-diameter pipe
The madial wall in road is set.
During practice of construction, multigroup protective folder is arranged on the both ends and middle part of core pipe, by the first pipe collar 2 or
Second pipe collar 3 clamps firewood pipe；Then, core pipe is put into large diameter pipeline together with protective folder, be supported on greatly by guide feet
On the tube wall of caliber pipe, it is inwardly inserted into.
The core pipe and great Kou that the pipe collar 2,3 of multiple guide feets 4 and first, second that nationality is fixed by relative position inserts needs
Footpath pipeline is isolated, and effectively can prevent both from colliding during insertion, with this ensure work progress core pipe and
Large diameter pipeline will not collide, and core pipe anticorrosive coat is complete after the completion of construction.
In certain embodiments, it is equipped with roller in whole guide feets 4.
In certain embodiments, the first pipe collar 2, the second pipe collar 3 include fixed part and removable section, the first pipe collar
2nd, the fixed part of the second pipe collar 3 is fixedly connected with support 1, and the first pipe collar 2, the removable section of the second pipe collar 3 are with can
Dismounting mode removably connects with corresponding fixed part.
In certain embodiments, the first pipe collar 2, the fixed part of the second pipe collar 3 and removable section are connected using bolt 5
Connect.
In certain embodiments, the first pipe collar 2, the fixed part of the second pipe collar 3 are fixed with welding manner and support 1 and connected
Connect.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
