In the alternative of the present embodiment, seal 105 is sealing ring.
Preferably, shown in Figure 1, sealing ring is set on the second pipe fitting 102, when the second pipe fitting 102 and straight sections
After 104 connections, that is to say, that when the thread segment of the second pipe fitting 102 is completely screwed into straight sections 104, sealing ring is located just at the
Two pipe fittings 102 and the junction of straight sections 104, it is achieved thereby that the sealing between the first pipe fitting 101 and the second pipe fitting 102.Its
In, sealing ring can use O-ring seal common at present.
In the alternative of the present embodiment, in addition to end cap 106, end cap 106 can be covered on the another of the first pipe fitting 101
On end.
In the alternative, the external diameter of the internal diameter of end cap 106 and the first pipe fitting 101 is adapted.
During casting concrete, end cap 106 is covered to the other end for being located at the first pipe fitting 101, that is, straight sections
It 104 free end, can effectively prevent cement or other debris from falling into the first pipe fitting 101, ensure inside the first pipe fitting 101
It is unimpeded, and then ensure that the slip casting process in later stage can be smoothed out.
Preferably, can set the portion of taking on end cap 106, convenient construction personnel install and removed end cap 106.Take portion
Form have it is a variety of, such as：The portion of taking can be the draw ring 107 shown in Fig. 2.
And for example：The portion of taking can also be projection.
It is, of course, also possible to anti-slip veins are set in the side wall of end cap 106, when choosing end cap 106, by increasing capacitance it is possible to increase hand and end cap
The frictional force of 106 side walls, consequently facilitating smoothly removing end cap 106.

In the alternative, the first pipe fitting 101 and the second pipe fitting 102 are the stainless steel tube of inner wall smooth, due to slip casting
Conduit uses plastic material, and strength and stiffness are poor, easily occur in concreting process, become by concrete extrusion
Shape, cause the later stage can not slip casting.
Preferably, the material of the first pipe fitting 101 and the material of the second pipe fitting 102 can be stainless using existing 304
Steel.
In the alternative of the present embodiment, the pipe external diameter of the first pipe fitting 101 is 25~40mm.
In the alternative, the pipe external diameter of connecting portion 103 is equal with the pipe external diameter of straight sections 104, is 25~40mm.
It should be noted that the cross-sectional area of the bending place of the first pipe fitting 101 can be more than the cross section of straight sections 104
Product, the slurry that such mode is advantageous in straight sections 104 successfully flow through kink, and are not easy to assemble in bending place, cause
Slip casting constricted flow.
In the alternative of the present embodiment, the pipe external diameter of the first pipe fitting 101 is 32.5mm.
, therefore, will because the aperture of the injected hole 110 of conventional slip casting disk 109 is about 32.5mm in current construction
The pipe external diameter of first pipe fitting 101 is arranged to 32.5mm, and the free end of connecting portion 103 can be inserted directly into injected hole 110, with
The first pipe fitting 101 and the connection of slip casting disk 109 are completed, not only increases slip casting efficiency, and enhance the slip casting of the present embodiment
The applicability of conduit.
Referring to shown in Fig. 3 and Fig. 4, by taking the construction of underground station structurally waterproof as an example, illustrate that the slip casting that the present embodiment provides is led
