Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an excavated soil reclaiming apparatus, and more particularly to a module structure of an excavated soil reclaiming apparatus which can be easily moved and installed.

[0002]

2. Description of the Related Art Excavated soil generated by excavation in gas pipeline construction, water supply and sewerage construction, electrical construction, etc., receives kneading due to excavation and loses the necessary subgrade support.
It was discarded as it cannot be used as a backfill material. For this reason, high quality earth and sand has been newly used for backfilling. Therefore, an excavated soil reclaiming device that improves the excavated soil and reclaims it so that it can be used for backfilling is disclosed, for example, in Japanese Patent Laid-Open No. 57-121086.

In this type of excavated soil reclaiming device, excavated soil and a soil stabilizer are blended, crushed and premixed, and then subjected to an impact action using a crushing mixer to perform crushing and mixing, followed by sieving. Sieving is performed using a classifier, the bottom of the screen is recycled for refilling as reclaimed soil, and the top of the screen is further repeatedly processed. The excavated soil reclaiming device is installed as a stationary device in the vast land, receives the excavated soil, performs the above-mentioned reclaiming process, and can be shipped as reclaimed soil. Alternatively, as an on-vehicle device, an excavated soil supply device, a soil stabilizer supply device, a mixing device, etc. are placed on a moving vehicle so as to be movable, and the vehicle is stopped at a place near the excavation work area to remove the excavated soil. Playback processing is possible.

[0004]

However, in the case of the stationary apparatus, the above-mentioned conventional configuration increases the carry-in distance of the excavated soil to the installation position due to the shift of the work area accompanying the excavation work, and the transportation cost. Increase in transportation costs and recycling costs, and further congest road traffic for loading, which is not preferable. If it is an in-vehicle device,
Since there is a restriction on the occupied space for placing it on a moving vehicle, etc., the placement of the required reclaiming device may be omitted, so that high-quality reclaimed soil cannot be obtained, or noise or vibration to neighboring areas, etc. May occur, which is not preferable.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and moves the excavated soil reclaiming device to the reclaiming site and the reclaiming device at the reclaiming site according to the progress of the excavation work. It is an object of the present invention to provide a module structure of an excavated soil reclaiming device, which can simplify installation of the excavated soil and can effectively prevent deterioration of the quality of the reclaimed soil.

[0006]

In order to achieve such an object, the present invention is an excavated soil reclaiming apparatus for reclaiming excavated soil to reclaimed soil by using a soil stabilizer or the like, which has a skid material. An excavated soil supply module having an excavated soil hopper and a excavated soil feeder provided with a grate on a gantry,
Soil stabilizer module in which silo of soil stabilizer and stabilizer feeder are placed on the platform with skid material, and crushing and mixing for crushing and mixing excavated soil and soil stabilizer on the platform with skid material A crushing and mixing module on which a machine and a chute are placed, and a sieving machine and a chute for sieving the crushed and mixed material into a reclaimed soil and a coarse soil are placed on a platform having skid materials. It is characterized by comprising a sieving module and a conveying means for connecting the respective modules to each other.

[0007]

According to this structure, the processing equipment required for the main process of the excavated soil reclaiming device is divided into a plurality of modular structures and is formed in a small size, so that the regenerating unit can be regenerated depending on the progress of the excavation work. It is possible to simplify the movement of the excavated soil reclaiming device to the treatment site and the installation of the reclaiming device on the reclaiming site, and moreover, it is possible to install it in an urban area or the like. Since each of the above-mentioned modules is loaded with loads in various directions generated by the operation of the processing equipment by the platform having the skid material, the operation of the processing equipment can be stabilized. Furthermore, since the excavated soil reclaiming device is formed without omitting the above-mentioned necessary treatment equipment, when reclaiming excavated soil into reclaimed soil using a soil stabilizer, etc., the quality of the reclaimed soil may deteriorate. It can be effectively prevented.
