Problems solved by technology

Traditional base road construction materials generally use natural sand and gravel materials, etc. However, such resources are becoming less and less, and the construction cost is also high, and the environmental damage and pollution are also relatively large
[0003] Traditional soil solidification materials such as cement, lime, and fly ash are commonly used in existing highway projects. However, there are obvious deficiencies in this, mainly manifested in: the formation of solidified soil strength is slow, and the early strength is low, which affects the construction progress; the solidified soil dries and shrinks. Large, easy to crack, poor water stability; solidified soil is limited by soil type
[0004] Larger, poor curing effect on clay, organic soil and saline soil with high plasticity index, or even no curing effect, so it is difficult to meet the needs of engineering construction development in central Zhejiang

Abstract

The invention discloses a method for preparing solidified soil by using a soil stabilizer. The method comprises the following steps that raw materials and a mold are prepared, a prepared soil stabilizer is weighed according to a certain proportion, the weighed soil stabilizer is slowly put into a beaker with the volume of 1L, a proper amount of water is added for stirring, stirring is performed for 10 minutes, after uniformly stirred, a solution is diluted to 5-7 mol / L, a solution I containing the soil stabilizer is obtained, oil or vaseline is applied over the inner wall of the modle, so thatdemolding is facilitated, and the step of sealing and curing comprises the substeps of maintaining a temperature to be 20 DEG C-40 DEG C and the humidity to be 50 RH-70 RH in a curing period. The method for preparing solidified soil by using the soil stabilizer has the beneficial effects that the requirements of engineering construction development can be met, the degradation problem of pollutionis avoided, and the method has the advantages of simple processes, easiness in production expansion, no pollution, no harm and the like, is wide in raw material source, has extremely high commercialperformance, can be used repeatedly without side effects, and can well satisfy the domestic and overseas market demands.

Description

technical field [0001] The invention relates to the field of foundation technology, in particular to a method for preparing solidified soil by using a soil solidifying agent. Background technique [0002] With the rapid development of my country's road infrastructure construction scale, the traffic volume and heavy-duty vehicles are increasing day by day, which puts forward higher requirements for the performance of roadbed and pavement structures of roads of all levels. In order to ensure the quality of highway engineering and reduce the engineering cost, it is very important to choose efficient road construction materials. Traditional base road construction materials generally use natural sand and gravel materials, etc. However, such resources are becoming less and less, and the construction cost is also high, and the environmental damage and pollution are also relatively large [0003] Traditional soil solidification materials such as cement, lime, and fly ash are common...
