Description
Technical field
The present invention relates to technical field of pipeline construction, in particular to a kind of municipal pipeline constructing device and construction method.
Background technique
In municipal works, the construction operation of pipeline is often had.
Application publication number discloses a kind of buried pipeline construction method for the Chinese patent of CN107191676A, including as follows
Step：
A, pipe trench is excavated, conveying material is in place；
B, after pipe canal digging, material are in place, pipe trench pipeline transfer carriage is set up, the pipe trench pipeline transfer carriage includes at least two
Type frame, the door type frame include pedestal, column, hoisting beam and jack, and the pedestal is set to the two sides of door type frame, the column
It is set on pedestal, the hoisting beam is erected on above two heel posts, has crossbeam sliding rail on the hoisting beam, and the crossbeam is sliding
It is provided with jack on rail, door type frame is erected on across being arranged in above pipe trench, and in the pedestal and pipe trench of door type frame
Between remain in advance place pipeline spacing；
C, pipeline is carried on ground reserved below pipe trench pipeline transfer carriage, pipeline assembly is welded into long pipeline, is being spelled
It is moved and is overturn using pipe trench pipeline transfer carriage subsidiary conduit in termination process；
D, after the completion of pipeline processing, pipeline is lifted by crane using pipe trench pipeline transfer carriage, the jack on each door type frame of simultaneously operating will manage
Road is transferred into pipe trench, and pipeline docking is completed；
E, pipe trench is backfilled, construction is completed.
The invention first excavates pipe trench, then pipeline is spliced at the construction field (site) in construction, after the completion of splicing, utilizes
Pipe trench pipeline transfer carriage lifts by crane pipeline and lower section into pipe trench, completes the construction of pipeline.
Disadvantage is that the construction method needs to excavate pipe trench, this construction ring this for street from ground in advance
For border, it will influence the normal pass of road, there are limitations.
There is a kind of method of jacking construction that can overcome above-mentioned defect at present, jacking construction is exactly non-excavating construction method,
It is a kind of piping laying construction technology do not excavated or excavated less.Construction by pipeline jacking method is exactly to borrow in the active well excavated in advance
The top power for helping the generation of the jacking devices such as hydraulic cylinder, jack, overcomes the frictional force of pipeline Yu datum hole surrounding soil, pipeline is pressed
The gradient of design heads into datum hole from one end close to active well, and the earthwork is transported.The completion of one length of tubing heads into after soil layer,
Lower second length of tubing continues jacking again.
But in the increased jacking construction of soil friction coefficient over long distances or in front of pipe motion, pipeline needs
Overcoming the frictional force of datum hole surrounding soil will increase, and especially proximate to the pipeline of active well one end, need to overcome in datum hole and own
The frictional force that pipeline is subject to, thus the pressure that the pipeline close to active well one end is subject to during jacking will greatly increase,
Even lead to Pipeline damage beyond the measuring body ability of pipeline itself.
