は既に知られている（特公昭54-35401号公報参照）。(Problem of the invention and its characteristic point) When a casing for sand pile formation is penetrated into the ground by a vibration penetrator, a secondary of a hydraulic winch that unwinds a wire that suspends a shock absorber above the vibration penetrator. A technique for detecting the pressure in the side hydraulic line and controlling the hydraulic winch using this detected value is already known (see Japanese Patent Publication No. 54-35401).
本発明は、この従来技術の改良を目的としているもので
あつて、その構成上の特徴は特許請求の範囲に記載した
とおりである。The present invention is intended to improve this prior art, and the structural features thereof are as set forth in the claims.

この点で本発明は前述の従来技術と異なる。When the pressure difference between the secondary side and the primary side is detected while the flow rates of the primary side and the secondary side of the hydraulic pipeline of the hydraulic winch are controlled to be equal as in the present invention, the wire is suspended even when the wire is being unwound. You can always accurately detect the pressure corresponding to the load,
In this respect, the present invention is different from the above-mentioned prior art.
（発明の具体的説明） 以下、図面により本発明の一実施態様を説明する。DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

イヤ７で吊持されている。In FIG. 1, reference numeral 1 is a casing for sand pile formation that is being penetrated into the submarine ground. A shock absorber 5 is attached to the shaft via a suspending wire 4, and the shock absorber 5 is suspended by a wire 7 wound around a hydraulic winch 6.
第２図に油圧ウインチ６の油圧管路で示されているが、
図中、８はドラム、９は油圧モータ、10は切換え制御
弁、11は油圧ポンプである。Although shown in FIG. 2 by the hydraulic pipeline of the hydraulic winch 6,
In the figure, 8 is a drum, 9 is a hydraulic motor, 10 is a switching control valve, and 11 is a hydraulic pump.
切換え制御弁10は、油圧モータ９への圧油送りの開始、
停止、方向の切換えの各制御の外、流量制御も行うが、
この流量制御において戻りの流量も送りの流量と等量に
制御されるようになつている。The switching control valve 10 starts the pressure oil feed to the hydraulic motor 9,
In addition to stop and direction switching control, flow rate control is also performed.
In this flow rate control, the return flow rate is controlled to be equal to the feed flow rate.

出し速度を変えるために流量を変えると圧力も多少変化
するので、この影響で圧力Pbは正確にはワイヤ７の吊り
荷重に対応して変化しない。When the hydraulic motor 9 is rotated in the wire unwinding direction while the flow rates on the feed side and the return side of the hydraulic pipeline are controlled to be equal, the pressure Pb of the secondary (return side) hydraulic pipeline b is 7
However, if the flow rate is changed in order to change the unwinding speed of the wire 7, the pressure will change slightly. Therefore, the pressure Pb accurately corresponds to the hanging load of the wire 7. And does not change.
本発明では、前述の流量を変えたときの圧力変化の影響

圧力Paとの差を検出し、これを用いて油圧ウインチ６の
制御を行うようにしている。In the present invention, in order to eliminate the influence of the pressure change when the flow rate is changed, the difference between Pb and the pressure Pa of the hydraulic line a on the primary side (feed side) is detected, and this is used to detect the hydraulic pressure. The winch 6 is controlled.

10を制御する。That is, the differential pressure detector 12 detects the difference between the pressure Pb and the pressure Pa and sends the detection signal to the arithmetic and control unit 13,
13 compares the sent detection signal with the set pressure signal,
Switching control valve by issuing appropriate control signal according to its size
Control 10
第３図は差圧検出器12の検出圧力Ｐと吊り荷重の関係を
図示したもので、１は吊つていない状態、すなわち全荷
重が地盤に預けられている状態のとき、IIは緩衝装置５

態のときである。FIG. 3 shows the relationship between the detection pressure P of the differential pressure detector 12 and the suspension load. 1 is the state where the load is not suspended, that is, the total load is stored on the ground, II is the shock absorber. 5
III is when it is expanding and contracting, and III is when it is fully loaded.
P1はＰの最大値、P2はＰの最小値、P3は設定圧力であ
る。Ｐ＞P3のときはワイヤ７の巻出しを高速で連続的
に行い、Ｐ＜P3になつた場合はワイヤ７を低速で一定
長巻出してから巻出しを停止し、ケーシング１が貫入

以後、，を繰返して、振動貫入機３の起振力が最大
限に貫入力として作用する状態、すなわち、振動貫入機
３以下の重量が地盤に預けられた状態でワイヤ７の追随
巻出しがなされるようにする。P 1 is the maximum value of P, P 2 is the minimum value of P, and P 3 is the set pressure. When P> P 3 , the wire 7 is continuously unwound at a high speed, and when P <P 3 , the wire 7 is unwound at a low speed for a certain length, and then the unwinding is stopped, and the casing 1 penetrates. When P> P 3 is reached, unwind the wire 7,
After that, by repeating ,, in a state where the vibration force of the vibration penetrating machine 3 acts as the maximum penetration force, that is, when the weight of the vibration penetrating machine 3 or less is stored in the ground, the follow-up unwinding of the wire 7 is performed. To be done.

Since the pressure difference on the primary side is detected and the hydraulic winch is controlled using this detected value, the pressure corresponding to the suspension load can always be detected accurately even when the wire is being unwound. The winch can also be controlled reliably in a preferred manner.
