られている。[Detailed description of the invention] During continuous pouring of invert concrete, a formwork is placed on top of the compacted ready-mixed concrete to prevent the formwork from rising due to buoyancy, and the pressure of this formwork consolidates the ready-mixed concrete for a short time. The method of forming and continuously pouring is described in patent application No. 55.
It is known from No. 164785 (Japanese Unexamined Patent Publication No. 57-89100).

必要があつた。 However, in cases where the fresh concrete has a high slump or the thickness of the inverted concrete is large, if the compaction of the ready-mixed concrete is performed in front of the forming equipment, the concrete under the formwork of the forming equipment may Due to the pressure of the frame and the lack of a device to completely prevent outflow at the front of the form, there were cases where the outflow occurred to the front and complete molding was not possible. In such cases, post-processing was time-consuming and it was necessary to frequently interrupt the molding operation.

するものである。 The present invention has been made to eliminate these drawbacks, and when high-speed pouring is difficult with low-slump ready-mixed concrete, even high-slump ready-mixed concrete can be compacted by completely preventing the concrete from flowing out under the forming equipment.

１０３で継がれている。 The present invention will be explained below with reference to the illustrated embodiments.
It consists of a weir plate 101 supported by an arm 100 that moves up and down with a cylinder 51 in front of the truck 3.
This weir plate 101 is higher than the ready-made invert and its width is narrower than the ready-made invert gap, the lower part is flush with the excavation surface, and a pin 102 is attached to the tip of the arm 100.
The weir plate 101 is supported by a ring chain 103 from a hub at the lower center of the arm 100 to prevent the weir plate 101 from flipping forward due to the pressure of fresh concrete (not shown).
また堰板１０１が生コンの圧力で浮上がること
を防止するため堰板１０１下部は成形装置側に傾
斜させるようリングチエーン１０３で引き止めら
れている。 Further, in order to prevent the weir plate 101 from floating due to the pressure of the fresh concrete, the lower part of the weir plate 101 is held back by a ring chain 103 so as to be inclined toward the forming apparatus side.
この堰板１０１と型枠１の間に生コンを充たし
て図示されていない棒状バイブレータ等で締固め
すれば形枠１の下のコンクリートが流出すること
はなく連続打設出来る。 If fresh concrete is filled between the weir plate 101 and the formwork 1 and compacted using a rod-shaped vibrator (not shown) or the like, concrete under the formwork 1 will not flow out and continuous pouring will be possible.
また堰板１０１に作用する生コンの圧力はアー
ム１００を介して台車３に前進方向の力が作用す
るため移動用の動力が少なくて移動出来る。 Further, the pressure of fresh concrete acting on the weir plate 101 causes a force in the forward direction to act on the cart 3 via the arm 100, so that the cart 3 can be moved with less motive power.
また打設終了時は型枠１１０の直前まで堰板１

０の上を成形装置を通過させる。 In addition, at the end of pouring, weir plate 1 is placed just before formwork 110.
01, the weir plate 101 is moved to the cylinder 51.
, and pull up the arm 100 to remove the formwork 11.

低く設置されている。 Furthermore, when invert concrete is placed with this device, even a poor mix of ready-mixed concrete can be sufficiently compacted compared to conventional ready-mixed concrete, so that the planned compressive strength can be obtained. The upper part of the formwork 110 is installed lower than the invert level by the aggregate size + α in order to sandwich gravel between the forming device and the formwork 110 and prevent the formwork 110 from collapsing.
この発明によるインバートコンクリートの成形
方法は以上の通りであり次に述べる。 The method for forming invert concrete according to the present invention is as described above and will be described next.
高スランプの生コンでも成形装置下のコンクリ
ートの流出を完全に防止して締固めしながら連続
打設でき、加工速度が早く、人手が省け、仕上り
精度も良い。 Even with high slump ready-mixed concrete, it completely prevents the concrete from flowing out under the forming equipment, allowing for continuous pouring while compacting, processing speed is fast, labor is saved, and the finishing accuracy is good.
