Abstract
The sinking and burying construction process for multiple-section immersed water supply or sewerage pipeline includes the steps of floating conveyance, sinking and underwater mating. It features that two or more sections of the pipe are flexibly connected and temporarily rigidly connected ashore before floating conveyance and the temporarily rigid connection is released after underwater mating while maintaining the flexible connection. The sinking and burying construction process has over 50 % reduced underwater mating work load, high work efficiency and greatly reduced cost.
Description
Technical field
The present invention relates to the sink method of construction of immersed tube water supply and sewerage pipeline, specifically a kind of sink method of construction of multitube section immersed tube water supply and sewerage pipeline.
Background technique
The underwater mating of immersed tube tunnel and immersed tube water supply and sewerage pipeline is the key link of sink construction, and it will be related to the quality that whole immersed tube is built.At present the Connecting format of immersed tube pipeline is broadly divided into and is rigidly connected and flexibly connects, when being rigidly connected with reinforcing bar in the joint area vertical communication, and be provided with the reinforcement steel plate, its strength and stiffness and pipeline section itself is comparatively approaching.Flexibly connect is to adopt the method that allows rotation and displacement, its structural type also has multiple, and with regard to the requirement of earthquake resistant design or adaptation uneven settlement, it is favourable adopting flexible joint, flexibly connect and when joint bears pulling force and shearing, still can guarantee its reliable water tightness.The structure of flexible joint mainly contains two kinds on cable wire type and steel plate type, the cable wire type only plays a position-limiting action to the axial force that earthquake produces, its flexibility is better than steel plate type, the Zhujiang River, river, river in Zhejiang Province immersed tube tunnel as China all adopt Ω shaped steel plate as the longitudinal spacing device, so that the axial displacement of flexible joint does not exceed rubber fastening band, the maximum displacement amount that allows can be arranged when keeping water tightness.
Present sink technology all adopts one to save transportation by driving, and carry out and one save butt joint under water, joint rubber fastening band sealing, rigidity or flexible jointing are made in the connection of each pipeline section the most at last.But the shortcoming of this method of construction is: pipeline section one saves transportation by driving, efficient is low, when the butt joint construction of carrying out pipeline section under water, because butt joint is many, the underwater mating technical difficulty is big, and the engineering cost height is concerning the immersed tube water supply and sewerage pipeline, adopt existing sink construction technology, engineering cost is just inevitable very high.
Summary of the invention
The sink method of construction that the objective of the invention is a kind of multitube section immersed tube water supply and sewerage pipeline of designing at the deficiencies in the prior art, its complete in the dry-docking by land before floating and sinking two joints or pipeline section more than two joints flexibly connects and is rigidly connected temporarily, the whole floating and sinking of the multitube section that will connect then, carry out underwater mating again, to be rigidly connected to be released at last temporarily and flexibly connect, sink method of construction of the present invention, significantly reduced the workload of underwater mating, engineering cost is low, high working efficiency.
The concrete technological scheme that realizes the object of the invention is:
A kind of sink method of construction of multitube section immersed tube water supply and sewerage pipeline comprises floating and sinking, underwater mating, it is characterized in that finishing by land before the floating and sinking flexibly connecting between two joints or the above pipeline section of two joints and being rigidly connected temporarily; To be rigidly connected to be released into again behind the underwater mating temporarily and flexibly connect.
Flexibly connecting of described each pipeline section is that two ends by waterstop are affixed with the flange of two pipeline sections respectively, and connects two pipeline sections by the several shear bars that are located between waterstop;
Temporarily being rigidly connected of described each pipeline section is flange and the connecting plate that is connected two pipeline sections by bolt;
Described will temporarily being rigidly connected under water is released into that to flexibly connect be that underwater demolition is fixedly connected on bolt and the connecting plate on two flanges.
The present invention can complete being operated in the land dry-docking of part pipeline section butt joint, and it can reduce underwater mating workload over half at least, adopt not only high working efficiency of the present invention, and engineering cost can reduce greatly.

Embodiment
Consult Fig. 1～Fig. 4, sink method of construction of the present invention, undertaken by following construction sequence:
1., landly finish two joints or the above pipeline section of two joints flexibly connects
The two ends of rubber fastening band 1 are cast in affixed pipeline section 2,3 in two flanges 4,5 respectively, and by the several shear bars 6 connection pipeline sections 2,3 that are located at waterstop 1 centre, pipeline section 2,3 seam crossings are filled with sealing compound 11, finish the fixedly connected of pipeline section flexibility, such connection can be two joints or the above pipeline section of two joints, the concrete pipeline section quantity that connects is decided with the technological scheme of floating and sinking.
2., landly finish temporarily being rigidly connected of each pipeline section
By bolt 7 fixedly connected two flanges 4,5, the bolt 8 fixedly connected connecting plates 9,10 that are located in the pipeline section 2,3, the interim connection that the pipeline section after bolt 7,8 connects has rigidity.
3., transportation by driving and sinking
With the whole transportation by driving of the pipeline section of finishing above-mentioned connection, sinking.
4., the butt joint of pipeline section under water
The pipeline section of sinking is connected with existing docking technique.
5., be rigidly connected to be released into and flexibly connect
Remove bolt 7 and the connecting plate 9,10 that is fixedly connected on the flange 4,5 under water, will be rigidly connected finally to be released into flexibly connects temporarily.
Claims (4)
1, a kind of sink method of construction of multitube section immersed tube water supply and sewerage pipeline comprises floating and sinking, underwater mating, it is characterized in that finishing by land before the floating and sinking flexibly connecting between two joints or the above pipeline section of two joints and being rigidly connected temporarily; To be rigidly connected to be released into again behind the underwater mating temporarily and flexibly connect.
2, sink method of construction according to claim 1 is characterized in that flexibly connecting between described each pipeline section is affixed with the flange of two pipeline sections respectively by waterstop, and connects two pipeline sections by the several shear bars that are located between waterstop.
3, sink method of construction according to claim 1 is characterized in that temporarily being rigidly connected between described each pipeline section is to connect the flange of two pipeline sections and the connecting plate in two pipeline sections by bolt.
4, sink method of construction according to claim 3 is characterized in that described will temporarily being rigidly connected is released into that to flexibly connect be that underwater demolition is fixedly connected on bolt on two flanges and the bolt on the connecting plate under water.
