Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant for producing fluidized soil used for backfilling excavated holes, and more particularly, to a fluidized soil capable of easily and inexpensively producing fluidized soil near a work site. The present invention relates to a chemically treated soil production plant.

[0002]

2. Description of the Related Art In recent years, there has been a case where a hole excavated on a road or a construction site is easily backfilled with excavated soil so as to be able to re-excavate. In this case, excavation is performed to facilitate excavation at the time of re-excavation or to secure soil strength of a predetermined level or more after backfilling a place where a pipeline or the like is buried using excavated soil. Water or muddy water and an improving material (for example, cement) are kneaded into the soil to produce a slurry-like backfill material, that is, a fluidized soil, poured into the excavation hole, and naturally solidified to secure a predetermined strength. The way to be done.

Conventionally, various methods have been used to produce fluidized soil used for backfilling. As a first example, there is a case where a fluidized soil is manufactured by a large-scale plant constructed at a predetermined base in an area. In this case, first, after mixing the remaining soil and water, large foreign substances and the like are removed, and then muddy water and an improving material are added and kneaded to produce a fluidized soil. After that, the fluidized soil is transported to many backfill sites around the base by a mixer truck or the like to perform backfill work. As a second example, there is a method in which the above-mentioned plant is temporarily installed near the backfill site, and fluidized soil is produced exclusively for the site.

Further, as a third example, see, for example,
There is one disclosed in 195253. According to the gazette, a bucket for soil injection, a premixer, and a main mixer are mounted on a gantry of a vehicle, and water is supplied from a water tanker near a backfill site and a solidified material is supplied as an improvement material. To produce a slurry-like backfill material (fluidized soil).

[0005]

However, the above-mentioned conventional fluidized soil production plant has the following problems. 1) In the first example, since the plant is large,
It is often constructed at a predetermined base remote from the backfill site, and therefore, it is necessary to transport the manufactured fluidized soil to the surrounding backfill site many times by a mixer truck. However, since the fluidized soil is so-called "raw" mixed with an improving material such as cement, it is difficult to transport the soil to a distant place. (For example, 20 km in the city center
It is almost the limit to carry about a distance. Also, there is a problem that transportation by a mixer truck is expensive. Furthermore, since the soil and water are simply mixed, it is difficult to mix them uniformly, and there is a problem that it takes a long time to produce fluidized soil. On the other hand, at the site of backfilling, costs for externally treating the remaining soil and industrial waste mud generated are required, thereby increasing the work cost at the site. 2) In the second example, since the plant is temporarily rebuilt near the site of the backfill, there is a problem that the transportation cost, the assembling cost, the disassembly cost, and the like of the plant are high and the cost is increased. 3) In the third example, the manufacturing apparatus is downsized so that the premixer and the main mixer can be mounted on a truck or the like, and the production of the fluidized soil is performed in a batch system. Ability is small. As a result, work cannot be performed efficiently in the case of large-scale construction.

SUMMARY OF THE INVENTION The present invention is directed to a fluidized soil production plant which can be installed in the vicinity of a backfill site in a short time at a low cost, has a large throughput, and can cope with a large-scale construction. It is intended to provide.
