Description

Technical Field

[0001] The utility model relates to a water seepage detection device, in particular to a water seepage detection device for construction engineering, belonging to the technical field of water seepage detection of building exterior walls. Background Art

[0002] Water seepage testing of building exterior walls is a method to evaluate the waterproof performance of building exterior walls, ensuring that the building's exterior walls can achieve the expected waterproof effect during design and construction.

[0003] The methods for detecting water seepage of building exterior walls mainly include pressure detection and water spray test. The water spray test simulates rain erosion by spraying water. Although its coverage area is large, its detection efficiency is low and it is easy to cause waste of water resources. Pressure detection is to use water to exert pressure on the building wall to detect its water seepage under the action of water pressure. It is mainly used for water seepage detection near building windows. Although its detection efficiency is high, whether water seepage occurs still needs to be observed by the naked eye by staff, and before testing, in order to ensure that the detection device and the wall can withstand sufficient water pressure, it is usually necessary to install and fix the detection device on the wall.

[0004] China's publicly authorized invention: CN111610132B discloses a wall water seepage performance detection device for construction, which relates to the field of building detection technology. The present invention includes a water immersion mechanism and a detection mechanism respectively installed on both sides of the wall; the detection mechanism includes a detection box body, the detection box body is a square box body, and the four edge sides of the detection box body are respectively provided with a fixed block, a guide hole is provided on the fixed block, and a fixed column is provided at the guide hole, and a suction cup is provided at one end of the fixed column; a "cross"-shaped fixed plate is provided at the other end of the four fixed columns, a threaded through hole is provided at the center of the "cross"-shaped fixed plate, and an adjusting screw is provided at one of the threaded through holes, and a through hole is provided at the end of the adjusting screw; a water immersion sensor is provided in the detection box body.

[0005] However, although the device can intuitively display the water seepage situation of the wall, it uses a suction cup to fix the device to the wall, which has poor stability, and its overall structure is too complicated. During the detection process, it needs to cooperate with multiple sets of electric telescopic structures to work, resulting in high production and use costs of the entire equipment. Therefore, a water seepage detection device for construction engineering is proposed. Utility Model Content
