Accordingly, fixed ring body is detachable ring body.
Clamping portion and pedestal can form overall structure in production, can also later period site welding.In pedestal and clamping portion
After being installed, can installation and adjustment bolt, during to pipe, by adjust bolt carry out conduit axis adjustment, reach fast
Speed, accurately to the purpose of pipe.Fixed ring body can unload after the completion of connecting to pipe.The internal diameter of fixed ring body and the outer diameter of pipeline
Accordingly, fixed ring body is detachable ring body.
Compared with prior art, the feature protruded is:
The technical program is fastened in one of two pipelines to pipe connection by the way that fixed ring body is arranged, using fixed ring body
End point is fastened in another end point of two pipelines to pipe connection using the fixed ear of fixed ring body, utilizes bolt
What be can be convenient is finely adjusted the position of pipeline, the adjusting that adjustment pipeline location is equipped with after meeting the requirements using fixed ear
The locking that bolt carries out position to another pipe head is fixed, and is carried out in the way of spot welding along the end point to two pipelines
It is fixed, then lay down to pipe connection, it is welded, to improve the efficiency to pipe, and can be prevented in the welding process
Dislocation improves welding quality and welding efficiency.
Further optimal technical scheme is as follows:
The fixation ring body is equipped with installation, disassembly buckle.By setting installation, disassembly buckle, fixed ring can be convenient
The installation fixation and postorder disassembly of body, installing and dismounting buckle structure can choose identical as the buckle structure of watch chain.
The fixation ring body is equipped with detachable unit part.
The end point of the detachable unit part is equipped with connecting hole, and installation is fixedly connected with shank of bolt in connecting hole, removable
The end point for unloading unit piece and detachable unit part passes through connection shank of bolt articulated connection.
By above-mentioned setting, the present apparatus is facilitated to be applied to the connection of the pipeline of different caliber sizes, connection can as needed
Removable unit part.

Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
Referring to Fig. 1, Fig. 2, pipe connection by fixed ring body 1, is arranged in fixed ring body 1 in a kind of directly buried pipeline
Fixed ear 2 forms；Interval setting 4 fixed ears, 2,4 fixed ears 2 divide 2 groups to be symmetrical arranged in fixed ring body 1, and 2 groups of line hangs down
Directly, in order to adjusting；Fixed ear 2 is equipped with pedestal 5 and clamping portion 3, and the diameter of a circle where the inner surface of clamping portion 3 is greater than by card
The outer diameter of the pipeline connect, clamping portion 3 are equipped with threaded hole, adjust bolt 4, and the internal diameter of fixed ring body 1 is corresponding to the outer diameter of pipeline,
Fixed ring body 1 is detachable ring body.
Fixed ring body 1 is equipped with installation, disassembly buckle 6.By setting installation, disassembly buckle 6, fixed ring body can be convenient
1 installation fixation and postorder disassembly, installing and dismounting buckle structure can choose identical as the buckle structure of watch chain.
Fixed ring body 1 is equipped with detachable unit part.
Referring to fig. 4, fixed ring body 1 is equipped with detachable unit part 10, and the end point of detachable unit part 10 is equipped with connecting hole,
Installation is fixedly connected with shank of bolt 9 in connecting hole, and detachable unit part 10 and the end point of detachable unit part 10 pass through connection spiral shell
Tightening latch 9 is articulated and connected.
In conjunction with Fig. 1, Fig. 2 and Fig. 3 it is found that connection method of the directly buried pipeline to pipe connection comprising the steps of:
(1) according to the size for the outer diameter for applying pipeline, production is to pipe connection, the high material production of material selection intensity
?；
(2) according to layout design pipeline mark high request, pipeline foundation sand-gravel cushion 7 of constructing, and excavated at pipe welding port
To pipe working pit 8；
(3) pipeline down tube is carried out to pipe operation, outwardly by fixed ear 2, by 1 cutting ferrule of fixation ring body to pipe connection
In the end of the pipeline connected to pipe, by the fixed installation of ring body 1 fastening, by the end for another pipeline for needing to connect pipe
It is moved into the fixed ear 2 to pipe connection, the end of two pipelines is made to be adjacent to required position, adjusted in fixed ear 2
Bolt 4 is adjusted to adjust the scale error of pipe welding port to be welded, until meeting error allows to require；
(4) junction of fix pipe connection two pipelines to pipe spot welding is carried out to fix；
(5) it unloads to pipe connection, the junction of two fixed pipelines to pipe of spot welding is formally welded.
The working principle of the present embodiment is as follows:
In the construction process, an end point of two pipelines to pipe connection is fastened in using fixed ring body 1, using admittedly
The fixed ear 2 for determining ring body 1 is fastened in another end point of two pipelines to pipe connection, pair that can be convenient using bolt
The position of pipeline is finely adjusted, and the adjusting bolt 4 that adjustment pipeline location is equipped with after meeting the requirements using fixed ear 2 is to another
The locking that a pipe head carries out position is fixed, and the end point of two pipelines is fixed in edge in the way of spot welding, then unloads
Fall to pipe connection, welded, to improve the efficiency to pipe, and can prevent from misplacing in the welding process, improves
Welding quality and welding efficiency.
Operation (test is managed with DN1200) after tested, the present embodiment has effect outstanding, has well solved pipeline pair
The problems such as pipe welding procedure progress is slow and misalignment of axe, according to previous construction, per pass weld bond opposite joint, welding need nearly 3 hours
It completes, 1 hour is only needed after using the present apparatus.Present apparatus material is easily purchased simultaneously, and price is low, can be made,
It can be produced with producer.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to change with equivalent structure made by description of the invention and accompanying drawing content, it is intended to be included within the scope of the present invention.
