である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for casting mortar into a trench drilled in a stabilizing liquid while replacing the mortar with a stabilizing liquid.

れている。Recently, in the construction of hill-stopping works in urban areas, in order to eliminate vibration and noise pollution, trenches are excavated underground while being filled with stabilizing liquid, and then reinforcing rods are sunk into the trenches.
After that, we decided to use cast-in-place concrete to construct a continuous underground wall, insert steel sheet piles or precast concrete members into the trenches, and replace the stabilizing liquid with cement bentonite mortar (hereinafter referred to as CB mortar). New construction methods have been adopted, including a method of solidifying, a method of mixing a solidifying agent with a stabilizing solution to solidify, and a method of using a hardening stabilizer.
これらの施工法のうち、安定液とＣＢモルタルを直換す

用いられているが、この場合、溝孔の上方から直接モル

して所定の強度を有する構築物が得られない。Among these construction methods, the method of directly replacing the stabilizing liquid and CB mortar involves absorbing the stabilizing liquid in the trench with a pump, mixing cement and sand with the stabilizing liquid, and sending it again into the trench. However, in this case, if mortar is directly poured from above the groove, the cement will separate while it sinks to the bottom of the groove, making it impossible to obtain a structure with the desired strength.
このために従来から第２図に示すように、トレミ管Ａを

よると、定期的にモルタル上面までの探深を行わねばな
らなく、トレミ管Ａの切り離し作業と合わせて多くの手
間を要し、その上、連続してモルタルを打設することが
できないという欠点を有する。For this purpose, conventionally, as shown in Fig. 2, mortar is poured into the slot B using a tremor tube A, and the mortar ○ is placed by pushing up the stabilizing liquid C from the bottom of the slot B. Manually measure the depth to the top surface of the mortar using the probing rod E, and compare the measured value with the length of the tremie tube to determine that the discharge port F of the tremie tube A is below the top surface of the mortar by a predetermined depth. However, according to this method, it is necessary to periodically conduct depth probing to the top surface of the mortar, which requires a lot of effort along with the work of cutting off the tremor pipe A, and in addition, It has the disadvantage that mortar cannot be placed.

ドラム２を回転自在に支承し、ベルト３を介して駆動モ
ータ−４によって駆動される。Also, it is possible to separate the tremor pipe A by analogizing the depth to the mortar surface from the amount of mortar cast and the cross-sectional area of the excavation without probing with rod E, etc., but in the unlikely event that the groove wall If the cross-sectional area of the slot is changed due to collapse of the mortar, the discharge port of the tremor tube will be located above the mortar surface due to an incorrect analogy, and the mortar will separate, making it impossible to obtain the desired strength.
In particular, when placing CB mortar, the stabilizing liquid in the trench is pumped up and mixed with cement and sand on site, and CB mortar has better fluidity (higher flow value) than concrete. For this reason, there were various drawbacks, such as the resistance when probing the mortar surface was so low that it was difficult to confirm it, and continuous pouring was not possible during mortar mixing. In order to eliminate these drawbacks, the present invention uses a winding drum installed on the ground to lower an injection hose to the bottom of the excavation hole to send out mortar, and at the same time disposes the mortar at a predetermined position above the discharge port of the hose. The interface meter detects the interface between the mortar and the stabilizing liquid, sends the signal to the drive motor of the winding drum, drives the winding drum, and in response to the rise of the interface, winds up the injection hose and closes the hose discharge port. is always held at a predetermined position in the mortar, the stable liquid level in the rising groove is detected, the stable liquid is collected, and the stable liquid is mixed with cement, sand, etc. again to make mortar, This is supplied into the slot through the injection hose 5, thereby providing an underwater mortar placing device that enables continuous and automated mortar placement. An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a support frame with approximately triangular sides installed on the ground.

It is connected and transported by. The ground mixer 24 is connected to an agitator 26 via a valve 25, passed through an injection pump 27, and then connected to a swivel joint 29 attached to the center of the hose winding drum 2 via a pipe 28.
The injection hose 5 is connected to the base end of the injection hose 5 via the swivel joint 29 for transportation. Next, a mode of placing mortar in the slot will be explained based on the above embodiment. After completing the excavation of the groove hole 7 of a predetermined depth, the stabilizer hopper 20, sand hopper 21, and cement hopper 22 are sent to the grout mixer 24 via the piping 23 for mixing, and the mixed CB mortar is transferred to the agitator.

を巻き上げ、吐出口８を上行させる。When the water level rises, the liquid level gauge 31 senses it and issues an electric signal, which drives the pump 14 to pump up the stabilized liquid 15 through the pump 14 and into the stabilized liquid storage tank 17 via the piping 16. The sand is sent into the stabilizer hopper and sent to two stabilizer hoppers by the pump 18 via the piping 19 for reuse. On the other hand, the layer thickness of the mortar 30 cast at the bottom of the slot 7 gradually increases, and the interface between the mortar 30 and the stabilizing liquid 15 rises, and the interface meter 9 attached to the predetermined position of the injection hose 5 The detection generates an electric signal, which is guided by the lead wire 10, passes through the rotor 11, the lead wire winding drum 12, and then the lead wire 1.
3 to the input side of the drive motor 4 of the hose winding drum 2, which rotates the hose winding drum 2 and connects the injection hose 5.

ものである。As the discharge port 8 moves upward, the interface gauge 9 also moves upward, and the stabilizing liquid 15
Once inside, the electric signal stops and the drive motor 4 stops. Since the mortar 30 is continuously discharged from the discharge port 8 of the hose 5 even when the drive motor 4 is stopped, the interface between the mortar 30 and the stabilizing liquid 15 rises and is detected again by the interface meter 9. Then, the hose 5 and the interface meter 9 are moved upward until the interface meter enters the stabilizing liquid, and in this way, the discharge port 8 of the injection hose 5 is always maintained in the mortar at a predetermined depth from the interface. Mortar is poured into the groove. In addition, in the above embodiment, the lead wire 10 connected to the interface meter 9 is wound around its own winding drum 12, but the present invention is not limited to this; If one end of the lead wires 10, 13 is connected to the rotating disconnection joint coaxially with the injection hose 5, the rotor 11 and the winding drum 12 are unnecessary, and the interface meter 9 does not necessarily need to be integrally attached to the injection hose 5.
