Automatic righting system for transmission tower foundation and control method of automatic righting system
An automatic righting system for a power transmission tower foundation comprises a carbonate soil layer arranged under the power transmission tower foundation, concrete bases arranged on the two sides of the carbonate soil layer, connecting devices arranged between the concrete bases and the power transmission tower foundation and urease mixed liquid boxes. The connecting device comprises an outer sleeve, a back-jacking rod, a first spring, a hydraulic jacking device and a protective cover, the protective cover is installed on the concrete base, the hydraulic jacking device is installed in the protective cover, one end of the outer sleeve is hinged to the transmission tower foundation, the other end of the outer sleeve is connected with the outer surface of the hydraulic jacking device through the first spring, and the back-jacking rod is inserted into the outer sleeve. The back-jacking rod is connected with a telescopic rod of the hydraulic jacking device; the urease mixed liquid box is installed in the transmission tower foundation, three chambers of the urease mixed liquid box are respectively filled with a urease solution, a urea solution and an expanding agent, the bottoms of the three chambers are all provided with outlets, and the outlets are provided with switches. According to the invention, the maintenance reliability is improved, and the maintenance cost is reduced.
