Abstract
The invention provides a shield pipe material which comprises a pipe sheet main body, a pouring structure, a plunger, an embedded part, a material injecting channel, a PVC spiral pipe and a protrusive part. The pouring structure is arranged in the middle of the pipe sheet main body and provided with the embedded part, the PVC spiral pipe is arranged in the embedded part, the plunger is arranged at the upper end of the PVC spiral pipe in a plugged mode, the lower end of the PVC spiral pipe is additionally provided with the material injecting channel, and the protrusive part is arranged under the material injecting channel. The shield pipe material is high in pouring speed and uniform in flow velocity, is formed at a time and can meet the actual requirements of a shield tunnel.
Description
Technical field
The present invention relates to a kind of section of jurisdiction, be specifically related to a kind of shield tubing for shield tunnel.
Background technology
Society is due to the continuous progress of science and technology now, and in order to meet the demand and the development in city improving life, most cities should
Use track traffic to alleviate the public transport pressure in this city, in order to meet the use of metro light rail, it is necessary to use tunnel
Section of jurisdiction supports tunnel internal outer wall, it is commonly known that the section of jurisdiction that shield tunnel out needs requires higher, also implies that,
Section of jurisdiction, in casting process, needs one-shot forming, and concrete is owing to having coagulability faster, when this just requires to pour, and stream
Speed the most also to be wanted uniformly, can be only achieved the needs of reality, and the shield duct piece needing a new mode that pours to produce for this is expired
Foot is actually needed.
Summary of the invention
For above problems of the prior art, the invention provides that a kind of speed of perfusion is fast, the uniform one-shot forming of flow velocity
A kind of shield tubing of being actually needed of met shield tunnel.
The present invention is achieved by the following technical solutions: a kind of shield tubing, including section of jurisdiction main body, pouring structure, plunger,
Built-in fitting, material feeding passage, PVC serpentine pipe, lobe, it is characterised in that: described body midsection position, section of jurisdiction is provided with one
Individual pouring structure, described pouring structure has a built-in fitting, is provided with PVC serpentine pipe inside described built-in fitting, described
PVC serpentine pipe lower end is equipped with a material feeding passage, and jump a queue a plunger in described PVC serpentine pipe upper end, described note
A lobe is had below material passage.Described material feeding passage is in suitable for reading little, and the big shape of end opening can be in horn-like.
Preferably, described lobe is a cone shape, is positioned at immediately below the centre of material feeding passage.
The invention have the benefit that the pouring structure middle part in section of jurisdiction main body, when conveniently pouring, the slip energy on both sides
Arrive simultaneously, reach one-shot forming effect, for the uniform effect of arrival more further, PVC is set in the position of sprue
Serpentine pipe, so can ensure stream material uniformly, in order to accelerate the speed of stream material, arrange a material feeding passage below PVC serpentine pipe,
This material feeding passage is suitable for reading identical with PVC serpentine pipe diameter, and end opening is bigger, so can improve slurry flow rate, in order to further
Raising even results, a lobe is set in the underface of material feeding passage, uniformly imitates to further improve material feeding
Really, improving flow velocity, this lobe is arranged to cone shape, in order to ensure the positional stability of PVC serpentine pipe, and PVC spiral
Pipe is arranged in built-in fitting, and built-in fitting is that steel matter is pre-welded on the steel frame construction within section of jurisdiction, has the most stable
Property, in order to prevent foreign body from entering pipeline in advance, increasing a plunger in import department, use quality of rubber materials, easy dress easily pulls out, should
The feature of invention is to have operating effect simplicity, the feature that pouring quality is good.
Accompanying drawing explanation
Fig. 1 is the structure chart of the present invention.
Fig. 2 is the partial enlarged drawing of pouring structure in Fig. 1.
In figure: 1--section of jurisdiction main body, 2-pouring structure, 3-plunger, 4-built-in fitting, 5-material feeding passage, 6-PVC serpentine pipe,
7-lobe.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, to this
Invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
Refer to Fig. 1 and Fig. 2, the invention provides a kind of shield tubing, including section of jurisdiction main body 1, pouring structure 2,
Plunger 3, built-in fitting 4, material feeding passage 5, PVC serpentine pipe 6, lobe 7, it is characterised in that: described section of jurisdiction main body
1 middle part is provided with a pouring structure 2, and described pouring structure 2 has a built-in fitting 4, and described built-in fitting 4 is internal
Being provided with PVC serpentine pipe 6, described PVC serpentine pipe 6 lower end is equipped with a material feeding passage 5, described PVC spiral
Jumping a queue a plunger 3 in pipe 6 upper end, has a lobe 7, described plunger 3 to use rubber below described material feeding passage 5
Glue material, described built-in fitting 4 is steel construction material, and described material feeding passage 5 is in suitable for reading little, and the big shape of end opening can
In horn-like, described lobe 7 is a cone shape, is positioned at immediately below the centre of material feeding passage 5.
Refer to Fig. 1 and Fig. 2, the present invention is implemented: arranges one in the centre position of section of jurisdiction main body 1 and pours knot
Structure 2, this pouring structure 2 is such formation, and on the internal steel shelf structure of section of jurisdiction main body 1, the steel matter of welding is pre-
Embedded part 4, built-in fitting 4 is internal equipped with a PVC serpentine pipe 6, and PVC serpentine pipe 6 upper port adds a plunger 3, at PVC
Serpentine pipe 6 lower end arranges a material feeding passage 5, arranges a lobe 7 in the lower section of material feeding passage 5, and this lobe can
Being pre-welded on the steel frame construction of inside, this programme is implemented, and in the template poured, pulls out plunger 3, mixed
Solidifying earth material slurry is from PVC serpentine pipe 6 even into material feeding passage 5, and slip is fallen in cylindrical lobe 7 again, uniformly
Flowing to other positions, complete this operation, slurry flow rate is the most more uniform, and one-shot forming quality is good, can meet and be actually needed.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Any amendment, equivalent and the improvement etc. made within principle, should be included within the scope of the present invention.
