[0050] It can be understood that the arc-shaped inner mold 2 and the arc-shaped outer mold 3 can be moved by relying on the running wheels 4 at their lower ends, thereby facilitating the mold opening of thin-walled arc-shaped components; wherein, the wheel stopper can lock the running wheels 4 to prevent the arc-shaped inner mold 2 and the arc-shaped outer mold 3 from moving at will.

[0051] In one embodiment, a ladder 5 is fixedly connected to the inner side of the arc-shaped inner mold 2 and the outer side of the arc-shaped outer mold 3 , and a running wheel 4 is disposed at the lower end of the ladder 5 .

[0052] It is understandable that the ladder 5 is provided to facilitate construction workers to climb to the upper end of the vertical mold, thereby facilitating the pouring construction.

[0053] In one embodiment, a working platform 6 is disposed at the upper ends of the arc-shaped inner mold 2 and the arc-shaped outer mold 3 , and the upper end of the ladder 5 is connected to the working platform 6 .

[0054] It is understandable that the working platform 6 provides a working position for the construction workers, thereby facilitating the construction workers to perform pouring construction on the working platform 6 .

[0059] In one embodiment, a placement rack 12 for placing the lower hopper 11 is disposed at the upper ends of the arc-shaped inner mold 2 and the arc-shaped outer mold 3 .

[0060] It is understandable that the upper ends of the arc-shaped inner mold 2 and the arc-shaped outer mold 3 can be used to clamp the lower hopper 11 together through the placement frame 12 to facilitate pouring with the help of the lower hopper 11.

[0061] In addition, in order to produce holes on thin-walled arc-shaped components, a bending mandrel can be installed at the corresponding position, one end of the bending mandrel is inserted into the vertical mold, the other end of the bending mandrel is located outside the vertical mold, and the bending mandrel is detachably connected to the vertical mold.

[0063] Divide the internal space of the vertical mold into several layers of parts to be poured along the height direction;

[0064] Pour cement mortar from the upper end of the vertical mold to the lowest layer to be poured, and start the vibrator at the corresponding height of the lowest layer to be poured;

[0068] It can be understood that this pouring construction method breaks down the pouring process into multiple continuous thin-layer pouring processes, reducing the risk of cracking caused by internal stress concentration of the concrete; at the same time, before pouring concrete in the bottom layer to be poured, cement mortar with the same water-cement ratio as the concrete is first poured to avoid defects in the bottom concrete caused by the separation of aggregate and mortar during the concrete pouring process.

[0069] It should be noted that the pouring construction method adopts a vertical mold configuration and casts the thin-walled arc-shaped components in layers vertically. It is a scientific, reasonable and efficient construction technology that can significantly improve the casting appearance quality of thin-walled arc-shaped components and reduce construction costs.

[0070] It should also be noted that when each layer of the to-be-casted part is vibrated at a corresponding height, the vibrators of the arc-shaped inner mold 2 and the arc-shaped outer mold 3 on each layer of the to-be-casted part must participate in the vibration.

[0071] In one embodiment, the pouring construction method further comprises the following steps:

[0072] After pouring concrete at each layer to be poured, use a plumb line to measure and confirm that the concrete has been poured to the top of the layer to be poured, and then start the vibrator at the corresponding height of the layer to be poured.

[0073] It can be understood that such operation can ensure that the concrete of each layer to be poured is poured in place.

[0074] In one embodiment, the pouring construction method further comprises the following steps:

[0075] After vibrating the concrete with a vibrator at the corresponding height of each layer to be poured, use a rubber hammer to knock on the corners of the vertical mold at the corresponding height of each layer to be poured, and judge whether there is a hollow sound;

[0076] If there is a hollow sound, start the vibrator at the corresponding height of the layer to be poured to continue vibrating;

[0077] If there is no empty sound, the vibrator at the corresponding height of the layer to be poured will no longer be started.

[0078] It is understandable that such operation can ensure good vibration effect of concrete at each layer to be poured, thereby ensuring that concrete at each layer to be poured reaches a specified density.

[0079] A specific pouring construction method is given below, which comprises the following steps:

[0080] The internal space of the vertical mold is divided into four layers of parts to be poured along the height direction; wherein the height of each layer of parts to be poured is about 1m;

[0081] Pour cement mortar from the upper end of the vertical mold to the first layer to be poured, the pouring height is about 5 to 10 cm, turn on the vibrator at the corresponding height of the first layer to be poured, and vibrate for 5 seconds;

[0082] Continue pouring concrete in layers in a straight line to the first layer to be poured until a 4.2m long plumb line is used to measure and confirm that the concrete has been poured to the top of the first layer to be poured. Then turn on the vibrator at the corresponding height of the first layer to be poured until no hollow sound is produced when a rubber hammer is used to knock on the corners of the vertical mold at the corresponding height of the first layer to be poured.

[0083] Pour concrete in layers in a straight line to the second layer to be poured until the concrete is poured to the top of the second layer to be poured using a plumb line measurement, and then turn on the vibrator at the corresponding height of the second layer to be poured until no hollow sound is produced when the corners at the corresponding height of the second layer to be poured of the vertical mold are hit with a rubber hammer;

[0084] Pour concrete in layers in a straight line to the third layer to be poured until the concrete is poured to the top of the third layer to be poured using a plumb line measurement, and then turn on the vibrator at the corresponding height of the third layer to be poured until no hollow sound is produced when the corners at the corresponding height of the third layer to be poured of the vertical mold are hit with a rubber hammer;

[0085] Pour concrete in layers in a straight line to the fourth layer to be poured until the concrete reaches the top of the fourth layer to be poured, and then turn on the vibrator at the corresponding height of the fourth layer to be poured until no obvious bubbles are discharged from the upper end of the concrete;
