Abstract

PURPOSE:To display capability of a buck hoe, by a method wherein, once excavated earth and sand are banked into a levee, the earth and sand are transferred by the back hoe so as to excavate deeply enough. CONSTITUTION:Earth and sand at an excavating spot 1 are banked into a levee 2 by a bulldozer. The banking is transferred by the use of a back hoe.

Description

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

Conventionally, a backhoe is used to introduce earth and sand into a stone picker, 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 is intended to fully solve this problem, and will now be described in detail with reference to the drawings.

In the ground 1 to be treated, such as a field having a predetermined area where excavation is desired, earth surface 1A corresponding to the treatment depth is scraped with a bulldozer or the like, and earth and sand are collected on a part of the ground 1 to build an earthen embankment 2, This earthen embankment 2 is removed from a backhoe 6, etc.
While excavating the earth embankment 2, the earth and sand are fed into a processing device 4 such as a stone picker.

Then, for example, the gravel removed by a stone picker (earth and sand) is spread on the excavated ground IA' and leveled using a bulldozer or the like until it is evenly distributed. 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 FIG.

As shown in FIG. 7, a portion 1A which is not excavated may be left in a part of the ground 1, and an earth embankment 2 may be formed on this portion 1A. In this case, the unexcavated portion 1A will be treated with a backhoe. Note that Figure 5 shows the case where the backhoe is processing the soil while riding on the earthen embankment.

As shown in FIG. 8, excavation treatment may be performed in the longitudinal direction of the earthen embankment 2 while it is on the ground.

Since the present invention is constructed as described above, A. The backhoe's digging capacity can be used to its maximum potential.

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

○、Embankment σ) Pretreatment allows the single-bed structure to be released, making backhoe excavation work easier.

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

E. Since the gravel-removed earth and sand is leveled and spread using a bulldozer, both the bottom and surface sides of the spread earth are made uniform.

F. When it rains, you can cover the earthen embankment with a sheet for curing.
After the weather improves, you can resume business.

Claims (1)

[Claims] In a predetermined area of the ground 1 where excavation is desired, earth and sand are collected in a part of the ground 1 while scraping the ground surface 1A corresponding to the processing depth, and an earth embankment 2 is built. Earth embankment 2 is constructed using backhoe 6, etc. An excavation method characterized in that while excavating the earth embankment 2, earth and sand are thrown into a processing device f4 such as a picker.
