Problems solved by technology

[0002] In the construction of construction projects, a certain amount of cement is mixed into the soil, and the cement soil is widely used because of its low cost, overcoming the digestibility of natural soil, and the strength can meet the engineering requirements. However, due to the increase in the strength of cement soil Slow, it takes more than 90 days to reach the standard strength, so the construction period is longer, because the cement soil is granular at the beginning of construction, it is not suitable for formless masonry, so the scope of application is not very wide, currently only in construction projects. In the processing, such as cement-soil mixing piles and roadbed materials in traffic engineering construction; and bagged soil can be used for formless masonry and throwing due to the constraints of bags, but because bagged soil is completely dependent on the constraints of bags, there is no To change the digestibility of the soil, when the bag is damaged, the function of the bagged soil will be lost, so the bagged soil can only be used as a temporary building material, and the site must be cleaned up after use

specific Embodiment

[0012] One fills the side slope, due to the short-term filling, under the action of consolidation and rain, there is a phenomenon of slippage. Due to the development of the business, it is necessary to build a house on the top of the slope. Before building the house, the side slope needs to be treated. The treatment method is to build a gravity retaining wall. The design requirements are: to build a gravity retaining wall with a length of 50 meters, a width of 2 meters and a height of 4 meters. The compressive strength requirement is: 1Mpa. In this area, the price of stonework is relatively high, and a large amount of waste soil needs to be excavated, and it is inconvenient to transport the waste soil out, the transportation distance is long, and it pollutes the environment; therefore, bagged cement soil is used for masonry, and the soil properties of the construction site are: Cohesive soil, prepared by taking soil on site to make a test block, to reach the unconfined compress...

Abstract

The present invention discloses one kind of bagged cement soil and its engineering application. The bagged cement soil has the advantages of both cement soil and bagged soil, including wide material source and only needing small amount of cement and knitted bags; high compression strength of the structure up to 1 MPs; needing small work area and less disturbance on slope; no environmental pollution; low cost; needing no adhesive; etc.
