The invention provides a method for force balance control over three transverse spinning rollers of a spinning machine. The method for force balance control over the three transverse spinning rollersof the spinning machine comprises the steps that the initial pressing positions of the spinning wheels and the offset distance between the spinning wheels are arranged; the initial pressing reductionrectifying moments and pressing reduction rectifying sampling periods are determined respectively; after the spinning wheels are in place, the pressure data of the spinning wheels are collected; trackof a third spinning wheel is determined, and the standard pressure value of the spinning wheels is determined; and in the initial pressing reduction rectifying moment of a first spinning wheel, according to the pressure data and the standard pressure value of the first spinning wheel collected, first time rectification is conducted on the pressing reduction of the first spinning wheel, and then rectification is conducted on the pressing reduction of the first spinning wheel in each pressing reduction rectifying sampling period. By means of the method for force balance control over the three transverse spinning rollers of the spinning machine, the method for controlling transverse force balance of the three spinning wheels in the spinning machining process can be solved; the sizes of spinning pressure of the first spinning wheel and the second spinning wheel are actively adjusted successively; the radial displacement variable of the three spinning wheels is calculated and adjusted automatically through a numerical control system; and the purpose of transverse force balance control over the three spinning wheels is gradually achieved.

The invention relates to an existing building slant rectification method based on electroosmosis technology. The existing building slant rectification method based on the electroosmosis technology comprises the steps that 1, a monitoring station and a monitoring point are arranegd; 2, an electrode bar is inserted; 3, electroosmosis slant rectification is carried out; 4, a conductive plastic drainage plate is driven; 5, a circuit is connected renewedly; 6, electroosmosis drainage is carried out; and 7, continuous electroosmosis is carried out. The existing building slant rectification method based on the electroosmosis technology has the beneficial effects that the existing building slant rectification method based on the electroosmosis technology can rapidly and effectively rectify slant and right an existing building, the operation is simple, the construction is fast, and the technical benefits are very obvious; and compared with a traditional slant rectification method, consumption of manpower and material resources is greatly saved, the construction time is shorter, the construction cost is relatively lower, and the economic benefits are obvious.
