Embodiment 1

[0037] Such as figure 1 with figure 2 As shown, the urban underground drainage pipeline leakage location system of the present invention includes:

[0038] Drain pipe 1, which is buried under the wall or floor;

[0039] The concrete layer 2 is wrapped on the outside of the drainage pipe 1; the concrete layer 2 below the drainage pipe 1 is embedded with several U-shaped groove-shaped waterproof layers 3, and the opening end of the waterproof layer 3 is sealed and connected with the drainage pipe 1;

[0040] Waterproof humidity detection device 4, it is embedded in waterproof layer 3 and reads the humidity data of waterproof layer 3; Waterproof humidity detection device 4 comprises controller 41, humidity sensor 42 and wireless transceiver module 43; Controller 41 performs humidity sensor 42 coding;

[0041] Wire duct 5, wire 6 is arranged in the wire duct 5; one end of the wire 6 passes through the wire duct 5, the concrete layer 2, and the waterproof layer 3 to electricall...

Embodiment 2

[0056] According to the urban underground drainage pipeline leakage location system provided in embodiment 1, embodiment 2 provides the construction method of this urban underground drainage pipeline, comprising the following steps:

[0057] S1, pouring and stacking concrete to form the bottom layer of the concrete layer: according to the ratio of 10%-15% of stones, 20%-30% of cement, 25%-35% of sand, and 15%-30% of water, the concrete is poured and piled up to form the bottom layer of the concrete layer;

[0058] S2, Pouring and stacking waterproof layer: After pouring the bottom layer of the concrete layer for 6 hours, arrange it in the concrete layer according to the ratio of 10%-15% of stones, 22%-35% of cement, 30%-40% of sand, and 20%-30% of water Pour and stack several U-shaped concrete models on the bottom layer, and seal and cover the inner wall of the concrete model with SBS waterproof rolls to form a waterproof layer; several waterproof layers are connected in sequen...

Abstract

The invention discloses an urban underground drainage pipe leakage location system and a construction method thereof, comprising: a drainage pipe; a concrete layer wrapped on the outside of the drainage pipe, embedded with several U-shaped groove-shaped waterproof layers, and the opening end of the waterproof layer is connected to the drainage pipe Sealed connection; a waterproof humidity detection device embedded in the waterproof layer to read humidity data, which includes a controller, a humidity sensor and a wireless transceiver module; the controller encodes the humidity sensor; a wire duct is installed inside, and one end of the wire passes through the The wire pipeline, concrete layer, and waterproof layer are electrically connected to the waterproof humidity detection device, and the other end is connected to the solar silicon battery panel; the positioning early warning device is used for positioning early warning when the drainage pipe leaks; the controller combines the coding and humidity data of the humidity sensor with the The pre-stored humidity data is compared, and the comparison information and code are sent to the positioning and early warning device through the wireless transceiver module. The invention has the advantages of real-time early warning and positioning of drain pipe leakage.

Description

technical field [0001] The invention relates to the field of water leakage detection and construction, and more specifically, the invention relates to a leakage location system for urban underground drainage pipes and a construction method thereof. Background technique [0002] Urban underground drainage pipes are intricate. With the frequent drainage and aging of drainage pipes, the leakage of drainage pipes often occurs. Whether it is the waste of precious water resources or the various economic losses caused by the leakage of drainage pipes, the leakage of drainage pipes must be paid enough attention to. Since the drainage pipe is installed under the wall or the floor, the leakage of the drainage pipe is not easy to be found, and it is not easy to check the leakage point after the leakage occurs. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned technologies, the present invention provides an urban underground drainage pipeline leakag...
