（産業上の利用分野）
本発明は軟弱地盤上に構築される構造物の不同沈下修正
方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for correcting uneven settlement of a structure built on soft ground.
（従来の技術）
埋立地等の軟弱地盤上に構造物を構築する場合に最も懸
念されるのは地盤の沈下に基く構造物の不同沈下である
。その対策として支持杭基礎の採用や地盤改良等の打手
が行なわれるが、状況に依っては充分な基礎構造が採用
出来ない場合がある。(Prior Art) When constructing a structure on soft ground such as a reclaimed land, the greatest concern is uneven settlement of the structure due to subsidence of the ground. Countermeasures include adopting support pile foundations and ground improvement, but depending on the situation, it may not be possible to adopt a sufficient foundation structure.
そうした場合は変位量を計測してそれに応した修正が必
要になり、一般にはジヤツキを使って修正することにな
る。In such a case, it is necessary to measure the amount of displacement and make corrections accordingly, which is generally done using a jack.
（発明が解決しようとする！１ｌｆｉ）ジヤツキは、操
作性が良く高出力が容易に得られる事から油圧ジヤツキ
が良く用いられる。(What the invention is trying to solve! 1lfi) Hydraulic jacks are often used because they have good operability and can easily produce high output.
修正にあたって、柱を１本ずつ順次若干量ずつ修正して
いく場合は特に問題ないが、全ての柱を所要修正量に応
し、同時に修正する場合となると問題が生しる。When making corrections, there is no particular problem when the pillars are corrected one by one by a small amount, but a problem arises when all the pillars are corrected at the same time according to the required correction amount.
第２図を用いて説明する。シリンダ４本で例示している

ライン迄修正する場合を考える。シリンダ（１ｄ）部が
１番高いので、これを固定してシリンダ（ｌａ〜ｌｃ）
を動かして修正する事になる。This will be explained using FIG. An example is shown using four cylinders. (la) to (ld) are hydraulic cylinders, (2a) to
(2d) is the flow I adjustment valve, (3) is the power unit, (5
) is a structure that is tilted to the keyaki in Figure 0. Let's consider the case where the structure is corrected to the dotted horizontal line. The cylinder (1d) part is the highest, so fix it and move the cylinders (la to lc)
You will have to move and correct it.
構造物を動かす訳であるから極めて微速で動かす事にな
るが、固定シリンダに近いシリンダ、図で言うとシリン
ダ（１ｃ）はその中でも特に微速か求められ、流量調整
弁の分解能範囲外となる０分解能範囲内で行うには高速
すぎて非現実的である。Since the structure is being moved, it must be moved at extremely slow speeds, but the cylinder that is close to the fixed cylinder, cylinder (1c) in the figure, is required to have particularly slow speeds, and is outside the resolution range of the flow rate adjustment valve. This is too fast and impractical to do within the resolution range.
即ち全シリンダを速度制御することは妥当でない。That is, it is not appropriate to control the speed of all cylinders.
本発明は、かかる問題点に対処するため開発されたもの
であって全シリンダで速度制御をすることを目的とする
。The present invention was developed in order to solve this problem, and an object of the present invention is to control the speed of all cylinders.

要圧より若干高めにセットしたことを特徴とする。(Means for Solving the Problem) The structure of the present invention to achieve the above object is to correct uneven settlement of a structure by supporting the structure with a plurality of hydraulic cylinders. In the method, one of the hydraulic cylinders is set as a fixed cylinder serving as a reference point, two or more hydraulic cylinders farthest from the fixed cylinder are set as control cylinders that perform speed control, and the other hydraulic cylinders are set to control the speed. It is characterized in that it is set to a free cylinder that does not perform control, and the system pressure is set slightly higher than the required pressure for the junkyard.

。(Operation) According to the present invention, the free cylinder moves at a required system pressure of 10 α, and the speed control cylinder follows at a controlled speed. That is, the speed of all cylinders can be restricted by a fixed cylinder and two or more control cylinders. There is a load difference between the free cylinder and the speed control cylinder, but if this needs to be reduced, the number of control cylinders can be increased.

la) ~ (1m) are cylinders, (2a) ~ (2m) are flow rate adjustment valves, (3) are power units, (4) are pressure setting valves, (5) are structures, and (a) ~ (-) are Indicates the position of the pillar. If uneven settlement occurs and the height decreases from column (a) to column (a+), cylinder (1a) is set as the fixed cylinder that serves as the reference, and the speed control cylinder has a large correction amount, resulting in a large amount of pomelo. If you choose cylinders that are far apart from each other, plane errors are less likely to occur, so for example, choose cylinders (1j) and (

2b) to (21) and (2k) are opened, and the flow rate control valves (2j) and (2m) are set to the required correction amount ratio of columns (j) and (m). As a result, the controlled speed of the structure is constrained by the columns (a), (j) and (m), so each column obtains a predetermined correction value.

Since the pressure is set slightly higher than the required pressure, by juxtaposing speed control and pressure control, it is possible to control speed within a sufficiently allowable error range, and as a result, it is possible to control the amount of correction.
