Description
Technical field
The present invention relates to push pipe guiding technique fields, it is more particularly related to which a kind of long distance curved pipe jacking is certainly
Action-oriented system.
Background technique
Pipe jacking tunnel driving technology is a kind of engineering construction technology of underground tunneling, is with modern underground engineering, traffic
What the development of transport, urban construction and electrical communications facility got up manages in water conservancy water delivery, water supply and engineering irrigation
The new technology that road is laid with, can not have to open cut with pipe-jacking technology, in the construction process to road when pipeline passes through road, river
Traffic, river aerial drainage do not have any impact, with the fast advantage of high degree of automation, saving manpower, speed of application, and
It can control ground sedimentation when excavation, while the influence to above ground structure can be reduced, it will not shadow when in addition excavating under water
The traffic of Xiangshui County face.Generally, tunnel axis is longer, in the biggish situation of buried depth, using pipe-jacking technology more economical rationality.
Jacking construction is a kind of piping laying construction technology do not excavated or excavated less, be exactly in working pit by means of
The top power that jacking device generates, overcomes the frictional force of pipeline and surrounding soil, pipeline is headed into soil by the gradient of design, and will
The earthwork is transported, and section pipe completion heads into soil layer and then lower second section pipe continues jacking, and principle is by means of main top oil
The thrusts such as cylinder and pipeline enclosure, relay well pass through tool pipe or development machine out of active well soil layer and are advanced in received well always
It slings, after pipeline follows tool pipe or development machine closely, is embedded between two holes.
What is involved is being excavated using few, i.e., active well will excavate jacking construction with received well, and not excavate, i.e., pipeline is not
Excavation technology carries out the laying or replacement of underground utilities, top tube diameter DN800-4500.Inbuilt pipe is wanted by active well handle
Son heads into soil, and the pipe in an active well can walk 1500 meters or more in underground, and can also curve walk, to get around one
A little underground utilities or barrier, jacking construction China coast developed area be widely used in Urban Underground water supply and sewerage pipeline,
The non-excavation laying of the various pipelines such as natural gas petroleum pipeline, communication cable.It can highway crossing, railway, bridge, high mountain, river
Stream, any building in straits and ground.It is constructed using the technology, a large number of earth clearance expense can be saved, reduced to environment dirt
The blocking of dye and road has significant economic benefit and social benefit.
Pipe-jacking technology has had evolved to very mature stage, ventilating system, reducing friction through injecting slurry technology, deslagging skill at present
Art, knife cutting system, propulsion system, transportation system of being unearthed, power supply hydraulic system etc. have all obtained sufficient development and perfect,
The breakthrough of relay well technology solves the problems, such as the thrust of long distance curved pipe jacking, be able to achieve distance greater than 2500 meters length away from
From jacking construction.
Although these technologies of push pipe are highly developed, underground pipe-driving survey is oriented to the application of not new technology, long
In the jacking construction of distance, measurement work occupies a large amount of time, seriously affects the progress and its economic benefit of jacking construction, mesh
The measurement guiding technique of preceding jacking construction includes following several:
1, traditional measurement method: installing prism on push-bench, carries out (i.e. out of starting well) from the beginning to the end each time
Measurement, calculates prism coordinate on push-bench, goes out head centre coordinate further according to prism coordinate transformation.But work as with construction not
Disconnected to carry out, tunnel is increasingly longer, and the time measured is also increasingly longer, is not able to satisfy the requirement of construction.Utilize traditional survey
Amount method another disadvantage is that measurement work can only stop driving in the case where carry out, machine during driving
In " blindness " state.Therefore any deviation occurred during machine driving carries out manual measurement after can only waiting, and
It determines that the position of machine can be just repaired later, not can be carried out instant remedial measure.
2, manual measurement: before tube coupling jacking, position and the posture of push-bench are measured by conventional measurement means, manually
Deviation is calculated, push-bench opertions engineering teacher tunnels next ring according to the deviation that survey engineer gives.During the domain tunnels
Opertions engineering Shi Wufa learns the position and attitude of current push-bench, according only to experience and feels to be judged, cannot achieve push pipe
Construction survey is oriented to the requirement of real-time, and in addition after jacking certain distance, survey engineer measures push-bench and needs from work
The position of coordinate basis pilot measurement to push-bench is measured push-bench position and posture needs a large amount of time, be unable to satisfy top by well
Pipe construction requires the requirement of measurement precise and high efficiency.
3, laser transit is oriented to: being installed target on push-bench, is installed laser transit, laser transit in active well
Emit laser beam, forms red hot spot on target, it is sharp on target in advance by laser beam and design axis trimming to parallel
The change in location of hot spot is the change in location of push-bench, which can intuitively become to the position of opertions engineering's teacher push-bench
Change, also have the real-time of data, but have the defects that as follows: 1. measurement data cannot save；2. be only used for jacking away from
From the straight line pipe-jacking project less than 400 meters；3. not being capable of measuring the attitude angle of push-bench；More than there is a problem of, Bu Nengman
The measurement demand for the long distance curved pipe jacking engineering that foot develops at present.
4, robot measurement is oriented to: installing robot measurement in well head, reflecting prism is installed on push-bench, works out engineering
Software control robot measurement measures the coordinate of the reflecting prism on push-bench, calculates position and the deviation and real-time of push-bench
It has been shown that, this kind of method can also increase robot measurement between active well and push-bench, reach the purpose of coordinate basis transmitting, with
Just it is applied to the Curve Pipe Jacking engineering of long range.The technology has real-time property, but there is following ask through field application
Topic: 1. due in pipe jacking tunnel there are serious Atmosphere Refraction, when robot measurement at a distance from push-bench more than 100 meters when,
Measurement vertical error is too big, and the data precision cannot be met the requirements；2. if increasing measurement machine between active well and push-bench
People, to reduce the influence of Atmosphere Refraction, the transmission error of plane coordinates (X, Y) is too big at this time, and the consistency of data compared with
Difference cannot reach the target of measurement guiding, in addition increase robot measurement, increased cost is too big.
There are many problems in the above various measurement guiding techniques, be not suitable for the measurement in long distance curved pipe jacking tunnel.
