Further, in the flexible connection structure for sealing large-diameter pipes through walls as described above, an expansion water-stop strip is provided on the sealing surface where the rubber sealing belt contacts the inner sealing ring and the outer sealing ring.

Further, the above-mentioned large-diameter pipe through-wall seal soft connection structure, wherein the rubber sealing belt is an Ω-shaped structure.

Further, the above-mentioned flexible connection structure for large-diameter pipes through walls, wherein the inner pressure plate and the outer pressure plate are connected to the inner sealing ring and the outer sealing ring by bolts respectively.

Further, the above-mentioned large-diameter pipeline through-wall seal flexible connection structure, wherein a leak detection tube is provided at the lowest end of the outer sealing ring, and a ventilation tube is provided at the highest end of the outer sealing ring.

Further, the above-mentioned large-diameter pipeline through-wall seal flexible connection structure, wherein, the inner sealing ring is welded on the outer wall of the pipeline, and the outer sealing ring is integrated with the concrete wall.

The beneficial effects of the utility model are as follows: (1) The rubber sealing belt is used for sealing, and the expansion water-stop strip is arranged between the sealing belt and the sealing surface of the inner and outer sealing rings, which achieves a very ideal sealing effect, because the expansion water-stop strip can swell when encountering water , the slight loosening of the bolts will not affect the sealing and waterproof effect; (2) The rubber sealing belt is designed as Ω-shaped, which can allow large deformation independently of each other; Replacement and overhaul.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail.

As shown in Figure 1, the utility model provides a large-diameter pipeline through the wall seal soft connection structure, including inner sealing ring 2, outer sealing ring 3, rubber sealing belt 4, bolts 7, inner pressure plate 5, outer pressure plate 6, The lowest end is provided with a leak detection pipe 8, and the highest end is provided with a vent pipe 9. The inner sealing ring 2 is connected to the pipe 1 by welding, and the outer sealing ring 3 is temporarily connected to the inner sealing ring 2 by using a temporary connecting plate 11, as shown in Figure 3. After the installation is completed, it is poured into a body with the concrete wall 12, and then the temporary The connecting plate 11; and the inner pressure plate 5 and the outer pressure plate 6 press the rubber sealing belt 4 with the inner sealing ring 2 and the outer sealing ring 3 through bolts 7 to achieve the effect of sealing soft connection. The structure of the rubber sealing belt 4 is shown in Figure 2. The rubber sealing belt 4 is designed to be Ω-shaped, which can allow relatively large deformation independently of each other. The expansion water-stop strip 10 is provided to achieve a very ideal sealing effect. Since the expansion water-stop strip 10 can swell with water, the slight loosening of the bolt 7 will not affect the sealing and waterproof effect.

As shown in Figure 4, the structure of the inner pressure plate 5 and the outer pressure plate 6 is arc-shaped, and the inner pressure plate, the outer pressure plate and the inner sealing ring and the outer sealing ring are respectively connected by bolts, which are easy to check, replace and overhaul.

The inner sealing ring 2 is welded with the large-diameter pipeline 1, and the outer sealing ring 3 is processed at the same time, and the bolts 7 for the temporary connecting plate are installed on the inner sealing ring 2 and the outer sealing ring 3, and the outer sealing ring 3 is connected to the temporary connecting plate 11. The inner sealing ring 2 is temporarily connected, temporarily integrated with the large-diameter pipe 1 , and installed in place simultaneously with the large-diameter equipment 1 . In order to prevent the temporary connecting plate 11 from damaging the inner sealing ring 2 and the outer sealing ring 3, one layer of linoleum is arranged between the temporary connecting plate 11 and the inner sealing ring 2 and the outer sealing ring 3.

After the installation is completed, the concrete of the wall shall be poured, and a temporary support shall be set inside the pipe during pouring to resist the lateral pressure during concrete pouring. After pouring is completed, remove the temporary connecting plate 11 between the inner sealing ring 2 and the outer sealing ring 3, and check whether the bolts 7 are intact, and install other uninstalled bolts 7 at the same time. Then install the rubber sealing strip 4 and the inner pressure plate 5 and the outer pressure plate 6.

In order to ensure the construction quality of the sealing structure, a hydraulic test should be carried out after the construction of the sealing structure is completed, and water is injected into the seam between the two sealing belts 4 through the leak detection pipe 8, and the ventilation pipe 9 is blocked after the water is filled, and then continue to pressurize Water injection, pressurization is divided into three times, each pressurization is 1/3 of the total pressure, and it is stable for 24 hours, the sealing structure should not leak, until the maximum water pressure reaches 1.25 times the pressure on the sealing structure.
