Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing apparatus for excavating soil. More specifically, at construction sites such as foundation work for buildings, soil improvement work, water-stop wall construction, and civil engineering works,
The present invention relates to a novel soil cutting device for treating soil such as earth and sand discharged from a hole, a groove, etc. into a state in which it can be effectively used without making it into waste.

[0002]

2. Description of the Related Art Conventionally, earth and sand discharged from a hole, a groove, etc. have been discarded as waste because they are inhomogeneous and unsuitable in terms of material for effective use in other purposes. .
That is, such sediments have various properties such as sand and clay depending on the discharged stratum, and include tree roots, rocks, and wood fragments, metal fragments, concrete fragments that are the remains of surface structures. This is because

However, due to social problems such as environmental pollution, it is becoming impossible to dispose of it, and the discharged earth and sand are carried out from the construction site and subjected to an appropriate homogenization treatment at another treatment site before being carried in. Although it is being considered to make effective use of it again at the construction site, the reality is that its feasibility is low because it takes time and cost to carry it in and out. Therefore, it is expected to develop a means capable of homogenizing the earth and sand discharged from the holes, grooves, etc. at a low cost in a short time.

On the other hand, as the hardening agent is improved, the hardening agent and the earth and sand are stirred and mixed in the inside of the hole without placing the earth and sand through the hole, and a building material such as a wall is placed to form the earth and sand. A method for effectively utilizing a part of the material has been provided (see Japanese Patent Application No. 1-79591 of the applicant's previous proposal). However,
Even in such a construction method, the degree of mixing with the curing agent changes depending on the state of the earth and sand, and the casting strength and the like are likely to be uneven, so that the earth and sand are also required to be homogeneous. Further, in this method, earth and sand are discharged by exploratory digging prior to placing the building material, and hardener mixed earth and sand may overflow from the drilling holes. There is also a demand for effective utilization of waste without making it into waste.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been made in consideration of the aforementioned development requirements and the like, and is an apparatus for treating soil such as soil that can homogenize soil at low cost in a short time. The challenge is to provide.
