Description
Technical field
The present invention relates to underground pipeline construction field, is specifically a kind of drag pipe construction method of 4 points of orientations.
Background technology
It is mostly by the way of steel pipe socket steel pipe during for needing the blind underground piping worn, such as need to pass through harbour.Such as
The difficult point of this operation is that crossline will be passed through from the open caisson reserved opening of pipeline path both sides, while also avoid underground
Existing object, passing through for pipe is drawn for such a 4 points orientations, and the supervisor and borehole wall, worm and shore protection stake collision etc. easily occurs
Problem, can cause golden drag pipe construction to fail when serious, therefore often have high requirement to the accuracy of such a construction operation.
The content of the invention
It is an object of the present invention to provide a kind of drag pipe construction method, it is high with construction efficiency, and poling is accurately special
Point.
In order to achieve the above object, the present invention is realized in：
A kind of drag pipe construction method of 4 points of orientations, including
Step 1, the reaming to east side, west side open caisson reserved opening, borehole cleaning operation：Using reamer from side open caisson reserved opening
Reaming, borehole cleaning operation are carried out to opposite side open caisson reserved opening, injects bentonite into hole in reaming procedure, in retaining hole
Lubrication；Meanwhile in reaming procedure on moment concern drilling machine moment of torsion and pulling force change, and record variable condition；
Step 2, after reamer reaches west side open caisson reserved opening, one section of the continued access amplification pipe between reamer and supervisor；
Step 3, returned by drilling rod machinery progress reamer and drag operation, should avoid rotating and recording reamer row in pipeline returning
Into data；
Step 3.1, when reamer is managed with amplification and supervisor will reach before the open caisson reserved opening of east side 5 meters, slow down and draw in
Speed, by east side open caisson reserved opening observe hole in sound and well in related soil property change, judge amplification pipe with
Whether grazing is produced between the borehole wall, so until whole be responsible for through east side open caisson reserved opening；
Step 4, after supervisor passes through east side open caisson, drilling rod machinery is monitored, record into drilling rod length, in river
Carry out back dragging supervisor to construct, according to the size of tube body pulling force, rotate tube body, if pulling force becomes larger, in rotary course, keep every
6 meters of rotations are no more than 3 circles, after be responsible for back and being pulled through 50 meters, when tension variations are little, use and instead of rotation drag with drawing
Construction；
Step 5, the length according to follow-up follow-up drilling rod, when return expansion device soon apart from the 10 meters of positions in west side riverbank when, reduction draws in speed
Degree, reduces speed and checks and whether there is pipe friction in open caisson again when supervisor is apart from 5 meters of west side riverbank；
Step 6, when returning expansion device and pass through west side riverbank safely, keep low speed to draw in, until supervisor is safe to pass through west side riverbank；
Step 7, remove back expansion device, drilling rod machinery, and poling is completed.
The drag pipe construction methods of 4 points of orientations, 30 meters of amplification pipe overall length, wherein 10 meters are DN300 wall thickness 8mm, 10
Rice is DN480 wall thickness 8mm, and connection supervisor uses 10 Miho Dockyard, 630 wall thickness 10mm Q235 threaded steel pipes；D300 meets D480 and is then connected to
D630 is managed, and is welded using argon Electricity Federation between pipeline, and wherein Q235 tubing and 20G pipes are welded, it is necessary to carry out weld bond preheating, are welded
After the completion of amplification pipe is tempered stress concentration phenomenon existing for welding between unlike material is eliminated with this.
This pipe penetration method compared with prior art, by setting amplification pipe to play reducing guiding role, while improves whole
The deformability of a steel pipe, in order to accurately pass through open caisson reserved opening.
Embodiment
The present invention is further illustrated below by way of specific embodiment.
A kind of drag pipe construction method of 4 points of orientations, including
Step 1, the reaming to east side, west side open caisson reserved opening, borehole cleaning operation：Using reamer from side open caisson reserved opening
Reaming, borehole cleaning operation are carried out to opposite side open caisson reserved opening, injects bentonite into hole in reaming procedure, in retaining hole
Lubrication；Meanwhile in reaming procedure on moment concern drilling machine moment of torsion and pulling force change, and record variable condition；
Step 2, after reamer reaches west side open caisson reserved opening, one section of the continued access amplification pipe between reamer and supervisor；
Step 3, returned by drilling rod machinery progress reamer and drag operation, should avoid rotating and recording reamer row in pipeline returning
Into data；
Step 3.1, when reamer is managed with amplification and supervisor will reach before the open caisson reserved opening of east side 5 meters, slow down and draw in
Speed, by east side open caisson reserved opening observe hole in sound and well in related soil property change, judge amplification pipe with
