Description
Technical field
The invention belongs to the monitoring technical field of submarine pipeline in shallow sea reclamation area, particularly relate to a kind of based on shallow sea reclamation area
The monitoring method of submerged pipeline.
Background technology
Submerged pipeline in hydraulic reclamation district, under the effect of upper load, it will settles downwards and produces displacement, if displacement surpasses
When crossing the maximum displacement that submerged pipeline allows when bearing upper load, pipeline will destroy.Along with the progress of hydraulic reclamation in district,
Submerged pipeline top mud layer can be increasingly thicker, recycles measurement and set after feeling out pipeline position according to traditional artificial diving
The displacement of standby monitoring submerged pipeline and sedimentation, cost is high, the cycle is long, and can not make monitoring and warning in time.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of and reduces time before work, operability
By force, it is achieved that in easy process conditions, the workable monitoring method to submarine pipeline in shallow sea reclamation area.
The present invention solves that technical problem is adopted the technical scheme that present in known technology:
A kind of monitoring method based on submarine pipeline in shallow sea reclamation area, it is characterised in that:
(1), select monitored area: according to Finite element analysis results, submerged pipeline stress increase position be sedimentation and deformation
Big section, this region is monitored area；
(2), detection submerged pipeline position: in the district of monitored area before hydraulic reclamation, use the mode of artificial diving to find out seabed
The accurate location of pipeline；
(3), monitoring platform is set: being provided with fixing monitoring platform above submerged pipeline in monitored area, monitoring is flat
Detection notch it is reserved with on platform；
(4), in reserved detection notch, it is provided with a row is perpendicular to the sleeve pipe of submerged pipeline, the distance from bottom seabed of sleeve pipe
Pipeline leaves certain safe distance；
(5), in above-mentioned sleeve pipe, feeler lever is transferred one by one, until determining that submerged pipeline is positioned at the lower section of which root sleeve pipe；
(6) position of the submerged pipeline, according to the 5th step determined, transfers feeler lever, and the bottom of described feeler lever should be with
The upper surface of submerged pipeline, now high by the top mark measuring measuring apparatus feeler lever and plan-position, this data conduct
The primary data of submerged pipeline position；
(7), interval some cycles, re-start the 5th and the step of the 6th, according to result of detection by measuring equipment weight
The new top mark height measuring feeler lever and plan-position, and contrast with the primary data in the 6th step, thus estimate Submarine Pipeline
The sedimentation of line and displacement.
The present invention has the advantage that with good effect: owing to the present invention uses technique scheme, above submerged pipeline
Arrange monitoring platform, its absolute altitude would generally be higher than hydraulic reclamation designed elevation, sleeve pipe be positioned at submerged pipeline distance above and
It is fixed on monitoring platform, when transferring feeler lever along sleeve pipe, can quickly find out the particular location of submerged pipeline, it is to avoid
Manually water is first descended again it to be carried out the disadvantage of displacement and settlement monitoring after feeling out submerged pipeline.Station during survey crew monitoring
On firm monitoring platform, it is equal to stand in land and measures, eliminate and affect prison because of stormy waves by surveying vessel
Survey the drawback of result.Monitoring personnel can go up monitoring platform at any time and measure, and do not affected by mud layer thickness above submerged pipeline,
Collection data are quick.
Accompanying drawing explanation
Fig. 1 is monitoring platform structural representation of the present invention；
Fig. 2 is the top view of Fig. 1.
In figure: 1, monitoring platform；2, detection notch.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing
Describe in detail as follows:
A kind of monitoring method based on submarine pipeline in shallow sea reclamation area, (1), selection monitored area: according to finite element analysis
As a result, it is sedimentation and deformation maximum section that submerged pipeline stress increases position, and this region is monitored area；
(2), detection submerged pipeline position: in the district of monitored area before hydraulic reclamation, use the mode of artificial diving to find out seabed
The accurate location of pipeline；
(3), monitoring platform 1 is set: refer to Fig. 1 and Fig. 2, is provided with solid above submerged pipeline in monitored area
Fixed monitoring platform, monitoring platform is reserved with detection notch 2；
(4), in reserved detection notch, it is provided with a row is perpendicular to the sleeve pipe of submerged pipeline, the distance from bottom seabed of sleeve pipe
Pipeline leaves certain safe distance；
(5), in above-mentioned sleeve pipe, feeler lever is transferred one by one, until determining that submerged pipeline is positioned at the lower section of which root sleeve pipe；
(6) position of the submerged pipeline, according to the 5th step determined, transfers feeler lever, and the bottom of described feeler lever should be with
The upper surface of submerged pipeline, now high by the top mark measuring measuring apparatus feeler lever and plan-position, this data conduct
The primary data of submerged pipeline position；
(7), interval some cycles, re-start the 5th and the step of the 6th, according to result of detection by measuring equipment weight
The new top mark height measuring feeler lever and plan-position, and contrast with the primary data in the 6th step, thus estimate Submarine Pipeline
The sedimentation of line and displacement.
Owing to the present invention uses technique scheme, at the monitoring platform that submerged pipeline is provided above, its absolute altitude would generally be high
In hydraulic reclamation designed elevation, sleeve pipe is positioned at submerged pipeline distance above and is fixed on monitoring platform, when under sleeve pipe
When putting feeler lever, can quickly find out the particular location of submerged pipeline, it is to avoid manually first descend water to feel out after submerged pipeline again
It is carried out the disadvantage of displacement and settlement monitoring.Stand on firm monitoring platform during survey crew monitoring, be equal to stand in
Land measures, and eliminates the drawback affecting monitoring result by surveying vessel because of stormy waves.Monitoring personnel can go up at any time
Monitoring platform is measured, and is not affected by mud layer thickness above submerged pipeline, gathers data quick.
The above is only to presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, all
It is based on the technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, belongs to
In the range of technical solution of the present invention.
