Description
Technical field
The utility model belongs to pipe curtain steel pipe technical field, and in particular to pipe curtain steel pipe.
Background technology
Pipe-roof method all takes as the trenchless technology for passing through road, railway, airport etc. in Japan, the U.S. and TaiWan, China
Obtained preferable effect.Pipe curtain steel pipe fore shaft is connected, and pipe curtain injects water-stop or mortar after being formed at fore shaft, forms sealing
Antipriming pipe curtain.Then under the protection of pipe curtain, after soil stabilization processing in pipe curtain, supported when excavating, until pipe curtain section
Excavate insertion, then pouring structure body；Or first box culvert cast-in-place in the active well of both sides, then drawn when excavating the soil body to drawing case
Contain.
Pipe curtain steel pipe presently, there are following defect：
(1) itself pipe shaft low intensity of the pipe curtain steel pipe of the big thickness of pipe wall of diameter；
(2) steel pipe is directly welded, the problem of easily leak occur；
(3) steel pipe's production work efficiency height, Safety and Environmental Protection are poor, and repair rate is high.
Utility model content
The purpose of this utility model is to solve above-mentioned prior art problem, and the pipe curtain steel pipe provided.
Pipe curtain steel pipe, including tube coupling one and tube coupling two；Tube coupling one and tube coupling two the docking end face is provided with chamfering, tube coupling
Inverted T-shaped bellmouth connecting plate is welded between one and 2 two chamferings of tube coupling；The bellmouth connecting plate is welded under with interface；Institute
It is staircase structural model to state interface, and middle part and two ends are respectively arranged with boss two and boss one, set between boss two and boss one
It is equipped with seal groove；Olecranon rubber ring is provided with the seal groove；The boss two faces bellmouth connecting plate lower end, boss two
Upper planar dimension be more than bellmouth connecting plate lower surface size；The boss two is as level on boss one.
Tube coupling one and tube coupling two two free ends are provided with adpting flange.
Floor is provided with the inside of the adpting flange, floor top is consolidated with the inner ring top of tube coupling one, tube coupling two respectively
It is fixed.
The beneficial effects of the utility model：The utility model reasonable in design, the pipe shaft that can solve pipe curtain steel pipe is strong

Embodiment
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but does not constitute to this reality
With new any limitation.
Refer to shown in Fig. 1 and Fig. 2, pipe curtain steel pipe, including tube coupling 1 and tube coupling 27；The tube coupling 1 and tube coupling 27
Docking end face, which is provided between chamfering, 27 two chamferings of tube coupling 1 and tube coupling, is welded with inverted T-shaped bellmouth connecting plate 4；It is described to hold
Mouth connecting plate 4 is welded under with interface 6, and the structure setting can be sealed using 2 63 pairs of lower ends of bellmouth connecting plate 4 of boss
There is provided the intensity of welding for stifled and support；The interface 6 is staircase structural model, and middle part and two ends are respectively arranged with boss 2 63
With boss 1, seal groove 62 is provided between boss 2 63 and boss 1；Olecranon rubber is provided with the seal groove 62
Circle 5, plays good sealing effectiveness, so as to reach the effect of waterproof；The boss 2 63 faces the lower end of bellmouth connecting plate 4,
The upper planar dimension of boss 2 63 is more than the lower surface size of bellmouth connecting plate 4；Plane is high on the boss 2 63 and boss 1
Degree is the same, and stickiness more preferably, reduces the generation in gap when welding.The utility model is set by the structure optimization of interface 6
Meter, it is possible to reduce the use of parts, is the problem of high intensity and waterproof can be achieved with less parts.
Tube coupling 1 and tube coupling 27 two free ends are provided with adpting flange 2.The adpting flange 2 is radially uniform
Bolt hole is provided with, for fixing, connecting use.
The inner side of the adpting flange 2 is provided with floor 1, the top of floor 1 respectively with tube coupling 1, the inner ring of tube coupling 27
Portion is fixed, and strengthens the structural strength of steel pipe.
Preferred embodiment of the present utility model described in detail above, but the utility model is not limited to above-mentioned implementation
Detail in mode, in range of the technology design of the present utility model, can be carried out to the technical solution of the utility model
A variety of equivalents, these equivalents belong to protection domain of the present utility model.
