Preferably, the step S3 is further comprising the steps of：
It is inflated the bilge well to default pressure and sprays the seal of detection fluid inspection weld seam.
Preferably, the default pressure is 0.015Mpa.
Preferably, the detection liquid is liquid soap.
Preferably, further include step after the step S4：
S5, after the application of the bilge well, existing school piping is connect with the crossing cabin piping.
Preferably, the existing school piping passes through flanged joint with the crossing cabin piping.
As described above, the bilge well coating process of the present invention, has the advantages that：By bilge well piping erection stage
In advance, row operation pressure after process Forward is shortened can be reached, segmentation application integrality is improved, reduce the broken of ballast tank coating
The purpose of ship building period, is shortened in requirement that is bad, meeting PSPC.
Description of the drawings
Fig. 1 is shown as the structural schematic diagram of the bilge well of bilge well coating process of the present invention.
Specific implementation mode
Illustrate that embodiments of the present invention, those skilled in the art can be by this specification below by way of specific specific example
Disclosed content understands other advantages and effect of the present invention easily.The present invention can also pass through in addition different specific realities
The mode of applying is embodied or practiced, the various details in this specification can also be based on different viewpoints with application, without departing from
Various modifications or alterations are carried out under the spirit of the present invention.
It please refers to Fig.1.It should be noted that the diagram provided in the present embodiment only illustrates the present invention's in a schematic way
Basic conception, component count, shape when only display is with related component in the present invention rather than according to actual implementation in schema then
And size is drawn, when actual implementation kenel, quantity and the ratio of each component can be a kind of random change, and its assembly layout
Kenel may also be increasingly complex.
As shown in Figure 1, Fig. 1 is shown as the structural schematic diagram of the bilge well of bilge well coating process of the present invention.In the present invention
In provide a kind of bilge well coating process, include the following steps：
S1, the assembly and welding for carrying out the bilge well segmentation stage.Modern shipbuilding pattern is modular shipbuilding, is divided into two
Construction phase, two construction phases are respectively segmentation stage and carrying stage.The segmentation stage is that sectional construction is small one by one
Module is segmented；The carrying stage is to carry to close up to form whole ship for module small one by one is segmented integral hoisting.In the present invention,
Bilge well is assembled and welded in the segmentation stage first, ensures the integrality and seal of sewage well construction.In present aspect
A preferred embodiment in, the angle of release junction of bilge well is welded, ensures that angle of release junction not will produce gap, ensures
The seal of sewage well construction provides condition for follow-up tightness test.
Crossing cabin piping 10 and sect cover plate assembly 20 in S2, installation bilge well.In the present invention, in crossing cabin piping 10 apart from dirt
At a certain distance from well bulkhead, be usually arranged as 130-270mm, crossing cabin piping 10 disconnected, ensure one section of crossing cabin piping 10 with
Bilge well bulkhead can weld completion in advance, have application condition of the bilge well in the segmentation stage in this way, to facilitate bilge well
Painting work segmentation the stage implement.Bilge well includes sect, in order to ensure the seal of bilge well, is usually passed through sect
Sect cover plate assembly 20 seals.In the preferred embodiment of the present invention, sect cover plate assembly 20 includes sect seat board 201, road
Door-plate 202 and pressure gauge 203.After being sealed to sect by sect seat board 201 and to road door-plate 202, pressure can be passed through
Table 203 grasps the air pressure pressure in bilge well in real time, convenient for fully understanding the sealing effect and control tightness test of bilge well
Pressure when middle inflation inside bilge well.The installation steps of crossing cabin piping 10 and sect cover plate assembly are as follows：By crossing cabin piping 10
It is soldered on bilge well, and interim bored plate is installed at the place of 10 end of crossing cabin piping；Sect cover plate assembly 20 is covered at sect.
Further, sect seat board 201, and road door-plate 202 of the installation equipped with pressure gauge 203 on the seat board of sect are covered at sect.
The one end of crossing cabin piping 10 far from bilge well is closed using blank flange, using close between sect ring support plate and the sect of bilge well
Property sect circle closing.
S3, the seal for detecting bilge well.Tightness test is carried out to bilge well.To crossing cabin piping 10 far from bilge well
One end using blank flange close, between sect ring support plate and the sect of bilge well using close property sect circle closing after, to dirt
Well carries out cabin air test, examines the close property of bilge well.In a preferred embodiment, tightness test is used to dirt
Well is inflated to default pressure and sprays and check that liquid detects the seal of weld seam.Further, in this embodiment default pressure
It is by force 0.015Mpa, specifically, in the present invention, default pressure can also be adjusted according to actual conditions or needs.It is being segmented
Stage completes close property in such a way that bilge well cabin is inflated, and the attaching of adhesive tape in the prior art is then eliminated, with segmentation
Application is completed together, improves the integrality of segmentation application
S4, terminate in tightness test, after the close property for ensureing bilge well, complete application is carried out to bilge well.
Further, further include step S5 after to bilge well application step S4：Terminate in the application of bilge well
Afterwards, existing school piping 30 is connect with crossing cabin piping 10.In a preferred embodiment, now school piping 30 and crossing cabin piping are logical
The connection of flange 40 is crossed, can adequately ensure the sealing effect of bilge well.Since the crossing cabin piping of raw sewage well is in view of pipe
The adjustment of row construction after the installation accuracy of system and reduction, pipeling design are to be installed by region, are implemented in the dock stage.Now to piping
It optimizes, in sewage well area using the form of a bit of existing school pipe, can ensure the integrality of the piping fitting-out of bilge well,
Condition is created for the air test of bilge well cabin.
To sum up, the present invention shifts to an earlier date bilge well piping erection stage, can reach process Forward shorten after row operation pressure,
It improves segmentation application integrality, the destruction for reducing ballast tank coating, the requirement for meeting PSPC, shorten the mesh such as ship building period
's.So the present invention effectively overcomes various shortcoming in the prior art and has high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology can all carry out modifications and changes to above-described embodiment without violating the spirit and scope of the present invention.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should by the present invention claim be covered.
