The invention discloses an online motor rotor temperature measuring probe which comprises a reflector, an infrared light source, a focusing mirror, a receiving element, a light filter and a heat insulation sleeve. The probe is integrally protected by the heat insulation sleeve, screwed on a shell or an end cover and different from a common infrared temperature measuring probe, the probe effectively overcomes the shortcomings of unstable reflection and polarized light of a rotor surface caused by rotation by the aid of the light filter, a measuring element is mounted in the heat insulation protection sleeve, heat shock of heat conduction on a photoelectric element is relieved, and mechanical shock of body vibration on the elements is decreased when a motor runs. The probe has the advantages that the probe is accurate in measurement and fine in safety, the effect on the structure of the motor is low and the like, the probe can be conveniently and rapidly mounted on the end cover of the motor, the temperature of the end face of the rotating rotor is continuously measured in real time, and the probe effectively solves the problems that heat loss and safety risks caused by a window formed in the end cover in the past, temperature measuring test paper is pasted on the surface of a rotor, the highest temperature can only be inspected in a split manner, and the temperature change process cannot be reflected.

The invention relates to a construction method for seepage anticipation and treatment of an underground continuous wall. The construction method includes the following steps that according to the construction condition of the underground continuous wall, a seepage detection point is selected; during construction of underground continuous wall, a detection pipe is buried at the selected seepage detection point; after the construction of the underground continuous wall is finished, a detection probe of a sonar measuring instrument is sent into the detection pipe for detecting, and a detection result is obtained; and grouting water stop treatment is conducted on the leakage detection point which the seepage coefficient is larger than the set range in the detection result. According to the construction method, whether the underground continuous wall has seepage hidden danger or not is detected in advance to ensure safety of foundation pit excavation, if yes, grouting water stop treatment is conducted timely, the risk of water and sand gushing during foundation pit excavation is avoided, probability of seepage of the underground continuous wall is decreased, and construction safety of a foundation pit is improved.
