Description

本発明による方法は、異なる土壌成分の土壌層を有する土壌の層構造を示す、予想される土壌プロフィルを制御および評価ユニットに入力すること、および異なる土壌成分の土壌層間に遷移が存在する作業深さを確定するために、制御および評価ユニットによって、入力された土壌プロフィルと関連付けて、検出される少なくとも１つの動作変数を設定することを特徴とする。 The method according to the invention involves inputting an expected soil profile into the control and evaluation unit, which indicates the stratification of the soil with soil layers of different soil constituents, and a working depth at which transitions exist between the soil layers of different soil constituents. The control and evaluation unit is characterized in that at least one detected operating variable is set in connection with the entered soil profile in order to determine the roughness.

本発明の基本的な考えは、土壌の作業中に土壌のタイプを決定するとき、建設地のために生成された土壌プロフィルが考慮されるという事実にある。前もって生成された土壌プロフィルは、異なる物質からなり、異なる強度と耐荷重能力を有する様々な土壌層の配列を示す。ここで、本発明は、建設地の土壌プロフィルは、局所的に大きく変化することがあるが、その場合、これらの変化は、土壌層の数および順序が変わらずに、土壌層の厚さまたは深さレベルに実質的に関係するという発見に基づいている。本発明によれば、土壌作業時、例えば、液圧駆動装置のトルクまたは出力とすることができる動作変数または動作パラメータが検出される。この動作変数は、土壌プロフィルの第１の土壌層と関連付けて設定される。次いで、特定の第１の作業深さにおいて動作変数の顕著な変化が確認された場合、本発明の発見に従って、これは、土壌層の変化によるものとされる。次いで、第１の作業深さでのこの変化は第１の層遷移として確定することができる。次いで、これに相当する変化が続く場合、第２、第３、およびそれに続く層遷移はそれに従って所与の作業深さにおいて確定される。 The basic idea of the invention lies in the fact that when determining the soil type during soil work, the soil profile generated for the construction site is taken into account. A pre-generated soil profile represents an array of different soil layers, made of different materials and having different strengths and load-bearing capacities. Here, the present invention provides that the soil profile of a construction site may vary greatly locally, but then these variations can be controlled by the thickness of the soil layers or the It is based on the discovery that it is substantially related to depth level. According to the invention, during soil work an operating variable or parameter is detected, which can be, for example, the torque or the power of a hydraulic drive. This operating variable is set in association with the first soil layer of the soil profile. If, then, a significant change in the operating variable is observed at a particular first working depth, then, according to the findings of the present invention, this is attributed to changes in the soil layer. This change at the first working depth can then be determined as the first layer transition. Then, if corresponding changes follow, the second, third and subsequent layer transitions are accordingly defined at the given working depth.

したがって、特別な基礎要素を製作するために、製作現場に実際に存在する土壌プロフィルを確定することができ、その場合、所定の深さにおける個々の層遷移は前もって確認された土壌プロフィルとは異なることがある。通常、前もって確認された土壌プロフィルは、特定の場所での１回または数回の試験掘削によって確認され、これから平均的な土壌プロフィルが確認される。それぞれの作業場所での実際の土壌プロフィルを特別に確定することによって、基礎要素の耐荷重能力に関して、また、基礎要素の製作に実際に必要な費用に関して信頼性の高い評価を行うことができる。これは、実際に存在する土壌条件に応じて、基礎要素の特に正確な費用ベースの計算および請求が可能になる。 Thus, for fabricating a particular foundation element, it is possible to determine the soil profile that actually exists at the fabrication site, where the individual layer transitions at a given depth differ from the previously confirmed soil profile. Sometimes. Typically, a previously identified soil profile is identified by one or more test excavations at a particular location, from which an average soil profile is identified. By specifically establishing the actual soil profile at each work site, a reliable assessment can be made of the load-bearing capacity of the foundation elements and of the actual cost of fabricating the foundation elements. This allows a particularly accurate cost-based calculation and billing of foundation elements according to the soil conditions actually present.

本発明の別の好ましい実施形態は、確認された動作変数に対して、特定の動作変数に対して保存された土壌特性値が、制御および評価ユニットによって照会および比較され、その時点の土壌値が決定されるという事実にある。例えば、制御および評価ユニットが、入力変数、例えばトルクを、結果として生じた出力変数、すなわち掘削ツールまたは切削ホイールの、結果として生じた回転速度と比較することによって、強度が変わった土壌層、したがって異なる土壌作業値の土壌層を貫入していると認識した場合、制御および評価ユニットは、確認されたその時点の土壌特性値または確定されたその時点の土壌層に従って入力変数を変えることができる。したがって、例えば、岩石の層が確定された場合、回転速度および送出力を低下させて、ツールの過大な摩耗を防ぐことができ、切削および剥ぎ取り条件を土壌層に対してできるだけ最適化するように与えることができる。データベース内に同一または類似の土壌特性値を有するデータセットが確認される場合、制御および評価ユニットは、確定されたデータセットに従って入力または動作変数を変えることができる、または、例えば、機械の操作者に対してこれをモニター上に表示することができる。自動モードでは、以前の動作変数は、土壌特性値に対して好適な動作変数によって置き換えることができる。したがって、この場合、加えられるトルクは、データベースの評価後、特定の土壌層に割り当てられた、確定された土壌特性値に応じて変えられる。 Another preferred embodiment of the invention is characterized in that the soil characteristic values stored for a particular operating variable are queried and compared by the control and evaluation unit to the identified operating variable and the soil value at that moment is lies in the fact that it is determined. For example, the control and evaluation unit compares the input variable, e.g. torque, with the resulting output variable, i.e. the resulting rotational speed of the drilling tool or cutting wheel, so that the soil layer with altered strength and thus When recognizing that a soil layer with different soil working values is being penetrated, the control and evaluation unit can change the input variables according to the confirmed current soil property value or the determined current soil layer. Thus, for example, when a rock layer is established , the rotation speed and delivery force can be reduced to prevent excessive tool wear and to optimize the cutting and stripping conditions as much as possible for the soil layer. can be given to If a data set with identical or similar soil property values is identified in the database, the control and evaluation unit can change the input or operating variables according to the determined data set or, for example, the operator of the machine can be displayed on the monitor. In automatic mode, the previous operating variables can be replaced by operating variables suitable for soil property values. Therefore, in this case, the applied torque is varied according to the determined soil property value assigned to the particular soil layer after database evaluation.

様々な土壌層を有する土壌に貫入させるときは特に、本発明の方法の変形によれば、土壌作業時に確認された土壌特性値、および作業深さまたは進行部分にわたって確認された土壌作業値に基づいて、制御および評価ユニットによって土壌プロフィルが確認および保存されることは有利なものとなる。データベースに保存されたデータに従って、特定の土壌タイプ、例えば粘土、砂、砂礫、岩石などを土壌特性値に割り当てることができ、その場合、これは、保存された土壌プロフィルも考慮して実行されることが好ましい。好ましくは、既存の遠隔データ接続によって、これらの値、したがって土壌プロフィルもまた、センターから制御および評価ユニット経由で照会することができる。このように、建設装置は、土壌作業のために使用するだけでなく、土壌プロフィルを調査するために探査または分析ツールとして使用することができる。 Especially when penetrating soils with different soil layers, according to a variant of the method of the invention, the Therefore, it is advantageous for the soil profile to be ascertained and saved by the control and evaluation unit. Specific soil types, such as clay , sand, gravel, rock, etc., can be assigned to soil property values according to data stored in the database, in which case this is also done taking into account the stored soil profile. is preferred. Preferably, by means of an existing remote data connection, these values, and thus also the soil profile, can be queried from the center via the control and evaluation unit. In this way, construction equipment can be used not only for soil work, but also as an exploration or analysis tool for investigating soil profiles.
