Изобретение касаетс строительства оснований различных сооружений на водонасыщенных св зных грунтах и может быть использовано как при строительстве, так и в процессе эксплуатации объектов жилого промышленного, военного, гидротехническо го и иного назначени .The invention relates to the construction of bases of various structures on water-bound associated soils and can be used both in construction and in the operation of residential industrial, military, hydrotechnical and other facilities.
Известно устройство дл электрохимического укреплени грунта, содержащее электроды-инъекторы с закрепл ющими растворами и источник высокого напр жени 1.A device for electrochemical soil stabilization is known, which contains injectors with anchoring solutions and a high voltage source 1.
В процессе пропускани через растворы закрепл ющих солей и грунт периодических импульсов тока в направлении от анода к катоду физико-механические свойства последнего улучшаютс быстрее, чем при укреплении непрерывным током, и в ходе химических .реакций в нем образуетс камнеподобное тело, однако из-за пол ризации грунта посто нно й составл ющей тока продолжительность этой обработки велика.In the process of passing periodic current pulses in the direction from the anode to the cathode through the solutions of the fixing salts and the soil, the physicomechanical properties of the latter improve faster than when strengthened by a continuous current, and a stone-like body forms in the chemical reactions, however, due to the floor Soil Constant Current Subsurface Duration is long.
Известно и другое устройство дл электрохимического укреплени грунта, содержащее основные электроды-инъекторы с закрепл ющими растворами, расположенные в укрепл емом грунте, источник управлени и сигнальную лампу 2.Another device for electrochemical ground stabilization is known, which contains the main electrode injectors with fixing solutions located in the reinforced ground, a control source and a signal lamp 2.
Недостатком известных устройств импульсного укреплени грунта вл етс низка эффективность использовани мощности источников электрической энергии. Так, коэффициент панезного действи , коэффициент мощ-ности и коэффициент использовани мощности источника, обратно пропорциональные скважности импульсов , имеют сравнительно невысокие значени . Кроме того, посто нна составл юща импульсов тока однополупериодного выпр млени приво дит к завышению типовой (расчетной) мощности и, соответственно, веса источника (трансформатора) электроэнергии из-за знакопосто нного насыщени его магнитной цепи. Поэтому эти устройства характеризуютс весьма низкими удельными энергетическими показател ми. Кроме того, дл ограничени величины переменной составл ющей тока источника в цепь этой составл ющей тока приходутс включать балластные резисторы, которые, рассеива избыточную мощность, дополнительно снижают КПД обработки грунта.A disadvantage of the known pulsed soil reinforcement devices is the low efficiency of using the power of electrical energy sources. Thus, the coefficient of usefulness, the power factor and the utilization factor of the source power, which are inversely proportional to the duty cycle of the pulses, have relatively low values. In addition, the constant component of the current pulse of a half-wave rectification leads to an overestimation of the typical (calculated) power and, accordingly, the weight of the source (transformer) of electricity due to the sign-constant saturation of its magnetic circuit. Therefore, these devices are characterized by very low specific energy indicators. In addition, to limit the magnitude of the variable component of the source current, the ballast resistors must be included in the circuit of this component of the current, which, dissipating the excess power, further reduces the efficiency of soil treatment.
