Description

Способ изготовлени  свай в грунте состоит в том, что в подготовленную скважину опускают электроды, заполн ют ее песком и пропускают ток высокой частоты до спекани  или расплавлени  песка. При остывании расплавленной массы образуетс  сва . Этот способ требует температуры нагрева песка пор дка 1760° и, в св зи с этим, применени  дорогосто щих электродов (графитных, угольных и т. п.).The method of making piles in the ground is that the electrodes are lowered into the prepared well, filled with sand, and a high frequency current is passed before sintering or melting the sand. As the molten mass cools, a pile is formed. This method requires a sand heating temperature of about 1760 ° C and, therefore, the use of expensive electrodes (graphite, coal, etc.).

Эти недостатки устранены в предлагаемом способе изготовлени  свай в грунте нутем заполнени  скважины песком с примесью добавок, понижающих температуру плавлени  песка (сульфат натри  и каменный уголь, известн к, известь, каменна  соль, сода). Температура плавлени  или спекани  песка с добавками примесей понижаетс  до 600-1200°. Расход тока на электропрогрев значительно сокращаетс , и в качестве электродов примен етс  обыкновенна  арматурна  сталь.These disadvantages are eliminated in the proposed method of making piles in the ground by filling the well with sand with admixture of additives lowering the melting point of sand (sodium sulfate and coal, lime, lime, rock salt, soda). The melting or sintering temperature of sand with admixture additives decreases to 600-1200 °. The current consumption for electrical heating is significantly reduced, and ordinary reinforced steel is used as electrodes.

На фиг. 1 изображена сва  в слабых грунтах (продольный разрез); на фиг. 2-сва  в водоеме (продольный разрез).FIG. 1 shows a pile in weak soils (longitudinal section); in fig. 2-pile in the pond (longitudinal section).

Дл  изготовлени  свай по концам диаметра пробуренной скважины вставл ютс  два электрода 1 из обычной арматурной стали. Скважина заполн етс  иеском 2 с примесью добавок, понижающих температуру плавлени  песка. В зависимости от устойчивости пересекаемых пород скважина проходитс  с обсадными трубами или без них. Через электроды от высокочастотного генератора пропускаетс  ток напр жением в зависимости от материала. Через 8-10 минут материал в скважине, подверга сь индукционному нагреву, расплавл етс  и, после остывани , представл ет собой твердое тело, стойкое против агрессивных вод. В зависимости от геологических и гидрогеологических условий способы работ по бурению скважины и получению сваи могут мен тьс . При мощном слое однородных песков, залегающих над грунтами с приемлемой, несущей способностью нри данных нагрузках, электроды забиваютс  в песок на заданном рассто нии друг от друга и на проектную глубину без усгройства скважины. Через электроды пропускаетс  ток высокой частоты и в результате плавлени  и остывани  песка образуетс  сва  непосредственно в грунте. В грунтах, насыщенных водой, пробуриваетс  скважина до коренных пород и закрепл етс  обсадными трубами 3. В трубу вставFor the manufacture of piles at the ends of the diameter of a drilled well, two electrodes 1 of conventional reinforcing steel are inserted. The well is filled with 10 with admixture of additives lowering the sand melting point. Depending on the stability of the intersected rock, the well passes with or without casing. A voltage is passed through the electrodes from the high frequency generator, depending on the material. After 8–10 minutes, the material in the well, after being subjected to induction heating, melts and, after cooling, is a solid that is resistant to aggressive water. Depending on the geological and hydrogeological conditions, the methods of drilling and producing piles may vary. With a thick layer of homogeneous sands overlying soils with an acceptable carrying capacity at these loads, the electrodes are blocked in the sand at a predetermined distance from each other and at the design depth without completing the well. A high frequency current is passed through the electrodes and as a result of the melting and cooling of the sand, a pile is formed directly in the ground. In soils saturated with water, a hole is drilled to the bedrock and secured with casing 3. In the pipe there is
