Description

Известны способы укреплени  переувлажненных св зных грунтов при помощи введени  в них извести, гипса или жженой магнезии в качестве добавки, аккумулирующей избыточную влагу, с последующей обработкой цементом.Methods are known for strengthening wetted bonded soils by adding lime, gypsum, or burnt magnesia to them as an additive that accumulates excess moisture, followed by treatment with cement.

В основном эти способы дают невысокую прочность грунтовой смеси при услови х влажности грунта, близкой к пределу текучести.Basically, these methods give a low strength of the soil mixture under conditions of soil moisture close to the yield point.

Предлагаемый способ укреплени  грунтов не имеет указанного недостатка .The proposed method of strengthening the soil does not have the indicated disadvantage.

Сущность изобретени  заключаетс  в том, что в переувлажненный грунт вводитс  добавка сернокислого магни  MgSO4 и известь с последующей обработкой цементом.The essence of the invention is that the addition of MgSO4 magnesium sulfate and lime with the subsequent processing of cement is introduced into the moistened soil.

Процесс изготовлени  известковоцементно-грунтовой смеси заключаетс  в следующем.The process of making lime-cement / soil mixture is as follows.

В грунт ввод т до 3% сернокислого магни  и 1-3% извести от веса сухого грунта. Добавка сернокислого магни  возможна до обработки грунта известью, вместе с нею или после внесени  извести. При грунтах с невысокой влажностью добавка сернокислого магни  производитс  в воду затворени .Up to 3% of magnesium sulphate and 1-3% of lime by weight of dry soil are introduced into the soil. The addition of magnesium sulphate is possible prior to the treatment of the soil with lime, with it, or after adding lime. In soils with low humidity, the addition of magnesium sulphate is produced in the mixing water.

Аккумул ци  избыточной влаги обычно длитс  3-4 часа, после чего полученную смесь измельчают и перемешивают с 6-12% цемента.The accumulation of excess moisture usually lasts 3–4 hours, after which the mixture is ground and mixed with 6–12% cement.

При влажности грунта, близкой к пределу текучести (0,8-1,0 W ), извес1ковоцементно-грунтовые смеси с добавкой сернокислого магни  в течение первой недели имеют механическую прочность на 40-60% выще прочности смеси без добавки. Введение сернокислого магни  ускор ет проц,есс твердени  грунтовой смеси во времени. Через сутки грунтовые смеси с добавкой MgSO4 имеют прочность, равную или несколько выше семидневной прочности смеси без добавки.When the soil moisture is close to the yield point (0.8-1.0 W), the cement-soil mixture with the addition of magnesium sulphate during the first week has mechanical strength 40-60% higher than the mixture without the additive. The introduction of magnesium sulphate accelerates the pro cess by hardening the soil mixture over time. A day later, ground mixes with the addition of MgSO4 have a strength equal to or slightly higher than the seven-day strength of the mixture without the additive.

Указанный способ укреплени  переувлажненных грунтов может примен тьс  при строительстве автомобильных дорог, аэродромов, площадок , канав и т. д.This method of strengthening wetlands can be used in the construction of roads, airfields, platforms, ditches, etc.

Л 140444- 2 Предмет изобретени L 140444- 2 The subject invention

Способ укреплени  иереувлажненных св зных грунтов посредством введени  добавок извести и цемента, отличающийс  тем, что, с целью ускорени  твердени  и повышени  механической прочности смеси , в грунт первоначально ввод т сернокислый магний в количестве до 3% и известь в количестве от 1 до 3% от веса сухого грунта, а после аккумул ции избыточной влаги полученную смесь измельчают и перемешивают с добавкой от 6 до 12% цемента.A method of strengthening the wet bonded soils by adding lime and cement additives, characterized in that, in order to accelerate the hardening and increase the mechanical strength of the mixture, magnesium sulfate is initially introduced into the soil in an amount of up to 3% and lime in an amount from 1 to 3% from weight of dry soil, and after accumulating excess moisture, the mixture is ground and stirred with the addition of 6 to 12% cement.
