Description
Technical field
The present invention relates to jacking construction tube coupling technical fields, and in particular to a kind of assembled tube coupling and preparation method thereof.
Background technique
Jacking construction is a kind of non-excavating construction method, and jacking construction is mainly used for subway entrance pedestrian passage and street
The construction of underground pedestrian passageway, and with the development of pipe jacking tunnel construction technology, jacking construction is also more and more used for tunnel
Engineering construction, construction by pipeline jacking method process are as follows: the top power generated in working pit by means of jacking device overcomes pipeline and surrounding soil
Tube coupling is headed into soil by the gradient of design, and the earthwork is transported by the frictional force of earth, and a tube coupling completion heads into after soil layer,
Lower second tube coupling continues jacking again, so successively heads into multiple tube couplings in soil.
There are mainly two types of production methods for tube coupling used in jacking construction, another one is produced on-site on construction ground
Kind is strange land production, then transports tube coupling finished product to construction site.For the mode of produced on-site, construction site is needed to have foot
The space of tube coupling is enough stored, and many tunnels build place and do not have enough spaces for making, storing tube coupling, therefore general use
The mode of strange land production makes tube coupling.
Produced if it is strange land, tube coupling is transported by grown place it is more difficult to construction site, in particular with push pipe tunnel
The cross dimensions of road tube coupling is increasing, and thickness is increasing, and weight is increasing, lifting appliance etc. is required it is higher and higher,
Simultaneously because tube coupling enormous size, produced on-site transport is relatively easy, if strange land produces, huge tube coupling transport needs
Road occupying, transport difficult.
In engineering, the tube coupling of common shield tunnel is formed by prefabricated pipe sheet assembling, after endless tube section score block processing
Assembling, is readily transported in this way, but since the section of jurisdiction stress condition of rectangular configuration is more complicated than round, how piecemeal and to divide
How to be connected after block, how waterproof is an extremely important problem to connector, and the tube coupling in jacking construction be subjected to it is huge
Thrust, during bearing huge thrust, how to keep the stabilization of tube coupling is also problem in need of consideration.
The Chinese patent of Publication No. CN108396777A describes a kind of big cross section for meeting segmentation prefabricating on-site consolidation
Tube coupling, including steel pipe joint, weld seam, the first piecemeal, the second piecemeal and bolt；Steel pipe joint is welded by the first piecemeal, the second piecemeal assembly
It connecing, both the first piecemeal, second piecemeal size and shape are identical and welding groove is reserved inside and outside Mosaic face,
First piecemeal, the second piecemeal Mosaic face end plate on reserve several bolts hole respectively, be located by connecting after splicing using bolt, first
Piecemeal, the second piecemeal assembly circlewise steel pipe joint.Tube coupling in the patent document is made of steel, then by different piecemeals
Part is welded, and the operations such as Mold Making, molten steel casting, workload also higher to later period welding requirements are related in manufacturing process
Greatly, at high cost, casting manufacturing speed slowly, low efficiency.
For these reasons, it is necessary to one kind be provided and be readily transported, convenient for structurally stable assembled pipe after production, assembly
Section.
Summary of the invention
The purpose of the present invention is to provide a kind of assembled tube coupling, the tube coupling for solving jacking construction in the prior art is not square
Just it transports, be inconvenient to the technical issues of making.
Second object of the present invention is to provide the production method of above-mentioned assembled tube coupling.
In order to solve the above technical problems, the technical scheme adopted by the invention is that:
