Abstract
The invention relates to a long distance pipe-jacking relay ring linkage construction method. At least three relay rings are started simultaneously for long distance pipe-jacking construction. The method specifically includes the steps of directing starting the first relay ring after jacking of the last relay ring is completed, and synchronously jacking a rear base lifting jack at the same time so that linkage between the first relay ring and the rear base lifting jack can be formed. By means of the method, the problems that when a plurality of relay rings are started in the super long distance pipe-jacking process through a traditional relay ring construction method, jacking efficiency is low, and no jacking may be conducted under the condition that more relay rings are started are solved. In the long distance pipe-jacking process, the multiple relay rings can simultaneously work, multi-point simultaneous jacking of long distance pipe-jacking can be achieved, and therefore the pipe-jacking construction efficiency is greatly improved.

Traditional relay ring controlling method is after last ring jacking completes, an articulating power jacking after operator's Advise By Wire, so repeatedly, the marching forward of " wriggling " formula, but this is for extra long distance push pipe, exists huge drawback: jacking efficiency is low.In the pipe-jacking project that this operating method is enabled at many relay rings, there are a lot of problems, and this problem can in larger relay ring is enabled the push pipe of scale, develop into cannot jacking situation.Shanghai City waste water control Bai Long Hong Kong Cinema district Nan Xian eastern section engineering 2.2 is marked wherein one section of push pipe length and is reached 2040m, and be Curve Pipe Jacking, construction control to relay ring is had higher requirement, and relay ring linked system will play very important effect in this project.
Summary of the invention
The present invention will solve existing traditional relay ring method of construction many relay rings in extra long distance push pipe to enable jacking efficiency low, and in the situation that more relay rings are enabled, may develop into the problem of situation that cannot jacking, and a kind of long-distance pipe jacking relay ring interlock method of construction is provided.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of long-distance pipe jacking relay ring interlock method of construction, at long-distance pipe jacking, enable at least three relay rings constructs simultaneously, concrete steps are: after in the end a relay ring jacking completes, directly start the first relay ring, the synchronous jacking of back seat jack simultaneously, forms the interlock of the first relay ring and back seat jack.
When the distance of the first relay ring and the second relay ring is long, or frictional resistance is when large, for preventing the second relay ring closure in the first relay ring jack-in process, makes the first relay ring and the 3rd relay ring form interlock, and the second relay ring and back seat jack form interlock.
In said process, adopt three relay ring composition relay ring interlock method of construction, when needs are raised the efficiency, increase relay ring quantity.
The invention has the beneficial effects as follows:
The present invention can solve traditional relay ring method of construction many relay rings in extra long distance push pipe, and to enable jacking efficiency low, and in the situation that more relay rings are enabled, may develop into the problem of situation that cannot jacking.The present invention, in long-distance pipe jacking jack-in process, can realize multiple relay rings and work simultaneously, realizes the multiple spot jacking simultaneously of long-distance pipe jacking, thereby significantly improves the efficiency of construction of push pipe.

Embodiment
Below in conjunction with concrete embodiment, further set forth the present invention.Should be understood that these embodiments are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after having read the content of the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, long-distance pipe jacking relay ring interlock method of construction of the present invention, long-distance pipe jacking relay ring interlock method of construction refers to enables to long-distance pipe jacking the method that three and above relay ring are constructed simultaneously, comprise and adopt the first relay ring 1, the second relay ring 2, the 3rd relay ring 3, back seat jack 4, tool pipe 5, concrete steps are: after the 3rd relay ring 3 jackings complete, the first relay ring 1 directly starts simultaneously, and back seat jack 4 is synchronous jacking also, has formed the interlock of the first relay ring 1 and back seat jack 4.Although can find out and start three relay rings, add that back seat jack always has 4 jacking intervals, in fact consume 3 intervals of only having of jacking duration, be equivalent to efficiency and improved 25%.
Also have more flexibly and select selecting to enable aspect relay ring, such as the distance of the first relay ring 1 and the second relay ring 2 is longer, or frictional resistance is enough large, in the first relay ring 1 jack-in process, be unlikely to allow the second relay ring 2 closures, so just can make the first relay ring 1 and the 3rd relay ring 3 form interlock, the second relay ring 2 and back seat jack 4 form interlock (depending on concrete condition setting), and efficiency can improve 50% in this case.
Above-mentioned is just example explanation take the relay ring interlock construction of 3 relay rings compositions, and the present invention is also just confined to the relay ring interlock method of construction of 3 relay rings compositions, and when along with enabling the increase of relay ring quantity, the raising meeting of efficiency is more obvious.The present invention, in long-distance pipe jacking jack-in process, can realize multiple relay rings and work simultaneously, realizes the multiple spot jacking simultaneously of long-distance pipe jacking, thereby significantly improves the efficiency of construction of push pipe.
