  • Consolidation Of Soil By Introduction Of Solidifying Substances Into Soil (AREA)

Description

Изобретение относитс  к строительству и может быть использовано дл  упрочнени  грунтов обратных засыпок , насыпей, слабых грунтов естественного сложени .The invention relates to the construction and can be used to strengthen the soil backfill, embankments, weak soils of natural composition.

Цель изобретени  повьшение эф фективности упрочнени  грунта.The purpose of the invention is to increase the effectiveness of soil consolidation.

Способ упрочнени  грунта осуществл ют следующим образом,The method of soil strengthening is carried out as follows.

В упрочн емый грунт ввод т инъ ектор и нагнетают через него сжатьй газ, например воздух и закрепл ющий раствор, например, силиката натри . Сжатый газ и закрепл ющий раствор нагнетают попеременноj ритмично. При этом происходит проникновение закрепл ющего раствора в поры грунта и уплотнение грунта с образованием полости вокруг инъектора По окончании нагнетани  заданного объема за крепл ющего раствора в инъектор нагнетают до отказа при заданном дав0319А2An injector is injected into the reinforced soil and a compressed gas, such as air and a fixing solution, such as sodium silicate, is injected through it. The compressed gas and the fixative solution are injected alternately rhythmically. When this occurs, the fixing solution penetrates into the pores of the soil and compresses the soil with the formation of a cavity around the injector. At the end of the injection of a given volume for the fixing solution, the injector is injected until failure at a given pressure 0319A2

лении твердеющий материал, например, глино-цементный раствор, который заполн ет образованную полость.The hardening material, for example, clay mortar, which fills the cavity formed.

Способ испытан при упрочнении 3 насыпного суглинка. Через забивной инъектор с перфорированной частью длиной 0,5 м в течение 10 мин нагнетают раствор силиката натри  плотностью 1,15 т/м с расходом 5 л/мин 10 и сжатый воздух под давлением 0,5- 1,0 ат, Зйтем ввод т глино-цемент- ный раствор. Радиус закреплени  грунта составл ет 0,4-0,7 м, радиус заполненной глино-цементным камнем t5 полости - 0,09-0,3 м, в грунте с начальной плотностью соответственно р55 и 1,30 т/м.The method is tested in the hardening of 3 bulk loam. A solution of sodium silicate with a density of 1.15 t / m with a flow rate of 5 l / min 10 and compressed air under a pressure of 0.5-1.0 atm are injected through a pick-up injector with a perforated part 0.5 m in length for 10 minutes. clay cement mortar. The soil fixing radius is 0.4-0.7 m, the radius of the cavity filled with clay-cement t5 is 0.09-0.3 m, in the soil with an initial density of p55 and 1.30 t / m respectively.

Благодар  периодическому введению 20 сжатого газа и закрепл ющего раствора достигаетс  одновременное уплотнение и закрепление рыхлого грунта.Due to the periodic introduction of 20 compressed gas and fixing solution, simultaneous compaction and fixation of loose soil is achieved.
