Abstract

PURPOSE:To make it possible to judge soil objectively by mounting an integrated soil judging device on the soil loaded on a dump truck, for a short time and simultaneously and quickly measuring colors, moisture, the presence or absence of mixed foreign matters and the like. CONSTITUTION:A dump truck 2 loaded with soil enters a measuring yard 3 and stops. Then, an integrated soil measuring frame 4 to which soil measuring instruments such as moisture meter are attached is arranged on a supporting frame 5 in the measuring yard 3. The frame signal indicating the stop of the truck is received, and the frame 4 is mounted on the soil 1 loaded on the truck by the craning force of an automatic lifting device 6. Then, the moisture meter and a density measuring device which are arranged on the frame 4 measure the moisture and the density with the radioisotopic method, respectively. A color measuring device measures the colors by the color TV method. A mixed- foreign-matter measuring device measures the presence or absence of the mixed foreign matters. The measured data of the individual measuring devices are displayed and recorded in a measuring chamber.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an automatic soil quality determination method.

[Conventional technology]

Conventionally, when soil is loaded onto a dump truck, the soil on the vehicle is observed from a high place, and the quality of the soil is determined visually based on the color of the soil, the presence or absence of contained impurities, and the type thereof.

In addition, to check for the presence of foreign substances, take the soil on the vehicle out of the vehicle, level it thinly, and then visually check it. To measure moisture, sample an appropriate amount of soil and place it in the measuring room. Moisture content may also be determined based on the weight loss after heating in an electric furnace.

[Problem to be solved by the invention]

However, such a determination method has the following problems.

(11) Quantitative measurements cannot be made for a single color of moisture that indicates the properties of soil.

Ru.

(3) Since quantitative measurements are not possible, comprehensive evaluation of soil quality must be based on intuition.

(4) Moisture cannot be measured in a test room in a short period of several minutes.

(5) Contaminant inspection requires a considerable amount of manpower and time because the soil that has been removed from the vehicle must be loaded again.

The present invention was proposed in view of the above circumstances, and instead of subjectively determining the soil quality based on the visual observation of an observer, the present invention can be realized by placing a comprehensive soil quality evaluation device on top of the load of a dump truck for a short period of time. The purpose of the present invention is to provide a method for determining soil quality that objectively determines soil quality by simultaneously and quickly measuring color, moisture, density, presence of impurities, etc. using individual measuring instruments.

[Means for solving lIa]

To this end, the present invention brings a dump truck loaded with soil to a measurement yard, where it automatically places a comprehensive soil measurement mount on top of the loaded soil in the trunk, and installs a moisture meter installed on the comprehensive soil measurement mount. , a density measuring device, a one-color measuring device, and a contaminant measuring device are used to quickly measure moisture, one-color density, and the presence or absence of contaminants, and the measurement results are displayed and recorded in the measurement room of the measurement yard. .

[Effect]

According to such a method, as shown in FIG. 1, in a measurement yard, a comprehensive soil quality determination device that is compact and capable of performing soil quality measurements in a short time is automatically placed on top of the soil loaded on a dump truck.

Then, as shown in Fig. 2, the soil quality comprehensive judgment device 4
The moisture and density measuring instruments installed in the area measure moisture using radioisotope methods.

The density is measured, the color measuring device measures the color using the color TV method, and the presence or absence of foreign matter is measured using the radar detection method, and the measurement data of each individual measuring device is displayed and recorded in the measurement room. .

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view, and FIG. 2 is a block diagram of FIG. 1.

As shown in FIG. 1, when the soil-loading dump truck 2 enters the measuring yard 3 and stops, a soil measuring instrument such as a moisture meter is installed in the measuring yard by the lifting force of the device 6. Place 4 on top of 1 in the trunk.

Then, as shown in Figure 2, the soil comprehensive island "S"L
The moisture measuring device and density measuring device installed in 1 → 4 measure moisture and density using a radioisotope method, the color measuring device measures color using a color TV method, and contaminants are measured using a radar detection method. The presence or absence of contaminants is measured in the measurement room, and the measurement data from each individual measuring device is displayed and recorded in the measurement room.

〔Effect of the invention〕

In order to effectively utilize excavated soil from construction work, etc., it is often transported by truck and collected in one place for temporary storage or soil improvement.In this case, appropriate treatment is required for the received surplus soil. In order to do this, it is necessary to measure the soil properties in a short time and to judge the soil quality based on the measured values.

On the other hand, 9 Normally, up to 1,000 trucks may be brought in per day at such a processing plant, but this becomes possible by using the determination method of the present invention.

Furthermore, if the weighing equipment yard is used as a weighing equipment yard, it is possible to simultaneously measure the weight of the load in addition to various soil quality measurements.

In short, according to the present invention, a dump truck loaded with soil is brought to a measurement yard, where a soil comprehensive measurement mount is automatically placed on top of the loaded soil in the trunk, and moisture measurement is carried out on the comprehensive soil measurement mount. The moisture content, density of nine colors, and the presence or absence of foreign matter are quickly measured using a two-color measuring instrument, a density measuring instrument, and a contaminant measuring instrument, and the measurement results are displayed and recorded in the measurement room of the measurement yard mentioned above to determine the soil quality. Instead of subjectively determining soil quality based on an observer's visual observation, a comprehensive soil evaluation device can be placed on top of a dump truck for a short period of time to determine color, moisture,
The present invention is industrially extremely useful because it provides a soil quality determination method that objectively determines soil quality by simultaneously and quickly measuring density, presence of foreign substances, etc. using individual measuring instruments.
