[0002] The drainage system is a conventional and essential system in buildings. The existing building drainage systems are all single-pipe drainage systems. Once the drainage pipeline leaks, it will affect the indoor environment and have an adverse impact on the use of the building. For some special buildings, such as hospitals and high-level biosafety laboratories, if the drainage pipeline leaks and is not discovered in time, it will lead to the spread of bacteria, viruses or potential pathogenic factors, and the consequences will be very serious.

[0003] Based on the above situation, the following two measures are usually adopted in the prior art: one is through-floor drainage, laying the single-pipe drainage pipeline under the building floor slab and installing a waterproof ceiling or a water baffle under the drainage pipeline; the other is in-slab drainage, by locally lowering the building floor slab in advance, laying the single-pipe drainage pipeline above the building floor slab, and installing the drainage pipeline, pipe fittings and related accessories in the cushion layer. The measures taken by the prior art cannot fundamentally achieve the effects of preventing leakage, discovering in time and repairing in time. Summary of the Utility Model

Therefore, it should not be construed as a limitation to the present utility model.

[0038] Referring to Figures 1-3 , this embodiment provides a casing-type anti-leakage drainage pipe system. The drainage pipe system includes: a main drainage pipe 1, and an outer lining casing 2 sleeved outside the main drainage pipe 1. A gap cavity 3 is provided between the outer lining casing 2 and the main drainage pipe 1. A detection and display device 31 for detecting leakage is arranged in the gap cavity 3. The detection and display device 31 is connected to a building control information system through a detection and display device connection line 32.

[0039] In this embodiment, the outer lining casing 2 is located outside the main drainage pipe 1. The connection part of the outer lining casing 2 pipe section, which is also the connection part of the main drainage pipe 1 pipe section, is the area where leakage is most likely to occur. The detection and display device 31 and the detection and display device connection line 32 are arranged at the pipe section connection. Through the detection and display device 31 and the detection and display device connection line 32, the characteristic values (such as humidity) on the inner side of the outer lining casing 2 and the outer side of the main drainage pipe 1 can be detected at any time, and the characteristic value information and the drainage pipe position information are transmitted to the building control information system.

[0040] In this embodiment, the material of the outer lining casing 2 is transparent. The main drainage pipe 1 is the main drainage and conveying pipe. The material and connection method of the main drainage pipe can be selected. There is a small gap between the outer lining casing 2 and the main drainage pipe 1. The detection and display device 31 is arranged in the gap. The detection and display device 31 will change color when it encounters water. Once the main drainage pipe 1 leaks, the leaked water will contact the detection and display device 31, and the detection and display device 31 will change color when it encounters water. At the same time, the characteristic values (such as humidity) on the inner side of the outer lining casing 2 and the outer side of the main drainage pipe 1 will change, and the information of the changed characteristic values will be uploaded to the building control information system in time. The building control information system will receive the leakage position of the casing-type anti-leakage drainage pipe system, and the detection and display device will change color when it encounters water, so as to effectively prompt the on-site maintenance personnel to quickly and accurately find the leak point.

[0041] In this embodiment, a pair of main drain pipe supports 33 are arranged at intervals in the gap space 3, and the main drain pipe supports 33 are integral with the outer lining sleeve 2. The outer lining sleeve 2 is composed of an upper part 21 and a lower part 22, and the upper part 21 and the lower part 22 of the outer lining sleeve are hermetically connected by an outer lining sleeve sealing screw 23. A sealing rubber pad 24 is padded at the sealing part of the upper part 21 and the lower part 22 of the outer lining sleeve.

[0042] When arranging the drainage pipe system, first install the lower part of the outer lining sleeve 2, then install the detection and display device 31 at the corresponding position, lay out the connection line 32 of the detection and display device, and then place the main drain pipe 1 on the main drain pipe support 33, cover the upper part 21 of the outer lining sleeve 2, and seal it with the outer lining sleeve sealing screw 23. A sealing rubber pad 24 is padded at the sealing part of the upper and lower parts.

[0043] In this embodiment, the connection mode of the outer lining sleeve 2 can be adjusted according to the different connection modes of the main drain pipe 1. The material of the main drain pipe 1 can be selected by the designer according to the position of the pipeline and the drainage water quality. For example, cast iron drainage pipes, plastic drainage pipes, stainless steel drainage pipes, etc. There are two common implementation forms of the connection mode of the outer lining sleeve 2:

[0044] One is that the main drain pipe 1 is connected by a main drain pipe flange 11. At this time, the outer lining sleeve 2 is connected by an outer lining sleeve connecting fitting 4. The main drain pipe flange 11 is fixed by a main drain pipe flange connection screw 12; the outer lining sleeve connecting fitting 4 can be processed and manufactured according to the size of the main drain pipe flange 11, and the purpose is to enclose the flange of the main drain pipe 1.

[0045] The other is that the main drain pipe 1 is connected by a socket fusion connection mode. At this time, the outer lining sleeve 2 also adopts a socket fusion connection mode for connection.

[0046] It should be noted that the connection mode of the main drain pipe 1 in this embodiment is not limited to flange connection and socket fusion connection, and can also be adhesive bonding, welding and other methods. Different implementation forms are only different in the connection modes of pipes and pipe fittings, and other working principles and protection contents are the same.

[0047] In this embodiment, a diversion port 25 is provided on the outer lining sleeve 2 for the overflow of the water seeping into the gap cavity 3 between the main drain pipe 1 and the outer lining sleeve 2 or for conveniently discharging the stored water in the gap cavity during maintenance.

[0048] The casing type anti-leakage drainage pipeline system provided by this embodiment can fully guarantee the safety of the building drainage system. Especially for some special buildings, such as hospitals, high-level biosafety laboratories, or other key drainage parts, it can play a role in timely detecting the leakage of the drainage pipeline and accurately positioning the leakage location, reducing the scope of maintenance and troubleshooting, and improving the maintenance efficiency.

[0049] The above are only the preferred embodiments of the present utility model, and are not limitations on the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as they do not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
