Description

DETAILED DESCRIPTION OF THE INVENTION The present invention seeks to provide an excavation method having a novel configuration.

Conventionally, backhoes are used to introduce earth and sand into stone pickers, but backhoes are not good at digging at shallow depths, so there are problems such as not being able to fully utilize their digging capacity.

The present invention aims to fully solve this problem, and one embodiment thereof will be described in detail below with reference to the drawings.

In the ground 1 to be treated, such as a farm field having a predetermined area where excavation is desired, earth and sand are collected on a part of the ground 1 while scraping the ground surface corresponding to the depth of treatment with a bulldozer, and an earth embankment 2 is built. Then, the earthen embankment 2 is removed by backhoe 3, etc.
It is configured to feed earth and sand into a processing device 4 such as a stone picker while excavating the earth embankment 2.

Then, for example, the gravel that has been removed by a stone picker is spread over the excavated ground IA' and leveled using a bulldozer or the like.

The above explanation is based on the case where the earth embankment 2 is carved out of the entire surface of the ground 1 to be treated using a bulldozer, but as shown in Figures 6 and 7, the ground 1
There is one person who does not excavate in a part of the area, and one person who does not excavate this part.
It may also have an earthen embankment 2 formed thereon.

In this case, the portion 1A'' that is not excavated will be treated with a backhoe.

Although FIG. 5 shows a case in which the backhoe is carrying out processing while riding on the earthen embankment, it is also possible to perform excavation processing in the longitudinal direction of the earthen embankment 2 while being on the ground as shown in FIG.

Since the present invention is constructed as described above, the excavation capacity of the backhoe A can be utilized to the maximum of 71''.

B When dumping into a stone picker, the difference between the work level of the stone picker's charging chute and the backhoe becomes smaller, making dumping easier.

Pretreatment for embankment C loosens the floor and makes it easier for backhoe excavation work.

D With conventional methods that do not involve embankments, if the depth of treatment is shallow, it is necessary to use a backhoe to scrape up the soil and then immediately dig in. However, with the proposed method, such work is not necessary, so the excavation cycle time is further shortened. can do.

E: The gravel-removed soil is leveled and spread using a bulldozer, so both the bottom and surface of the spread soil are uniform.

F In case of rain, you can cover the earthen embankment with a sheet for curing.
They can resume work as soon as the weather improves.

Claims (1)

[Claims] 1. In a predetermined area of ground 1 where excavation is desired,
While scraping the ground surface 1A corresponding to the treatment depth with a bulldozer or the like, the earth and sand are collected on a part of the ground 1 to build an earth embankment 2, and this earth embankment 2 is excavated using a backhoe 3 or the like. While doing so, the earth and sand are thrown into a processing device 4 such as a stone picker that is accompanied by the backhoe 3, and this processing device 4
Ground IA where excavated soil 5 after removing gravel discharged from
An excavation method characterized by leveling the area uniformly using a bulldozer etc.
