The molding method may include:
s101, assembling a first pouring template on the table top, determining a first pouring cavity forming the base 1, and pouring active powder concrete into the first pouring cavity.
In the embodiment of the invention, a working table can be preset for manufacturing the floating body, and a first pouring template is assembled on the working table to determine a first pouring cavity for forming the base 1. Wherein the first casting form may comprise a plurality of sections. The first pouring template of each part can be fixed in a detachable mode, and active powder concrete is poured into the first pouring cavity. The Reactive Powder Concrete (RPC) has better compressive strength and corrosion resistance, and can effectively reduce the weight of the Concrete. Thus, the foundation 1 made of the reactive powder concrete can be used in a corrosive environment such as a sea area for a long time, and the buoyancy of the floating body can be ensured and the structural stability of the floating body can be improved.
S102, performing steam curing on the reactive powder concrete in the first pouring cavity for a first preset time period under the condition that the first pouring cavity is determined to be poured.
In the embodiment of the invention, when the reinforced wall 3 or the side wall of the base 1 is fully poured with the reactive powder concrete, the first pouring cavity is determined to be poured. And at the moment, steam curing is carried out on the active powder concrete in the first pouring cavity, so that the curing of the base 1 is accelerated in a steam heating mode, and the production efficiency of the floating body is improved. After a first preset time, it may be determined that the base 1 is completely cured, and at this time, a portion of the first casting template located in the base 1 may be removed, so as to perform the next process.

In the embodiment of the invention, when the second pouring cavity is observed to be filled with the active powder concrete, the pouring of the second pouring cavity is determined to be finished. And at the moment, steam curing is carried out on the reactive powder concrete in the second pouring cavity, so that the curing of the upper cover 2 is accelerated in a steam heating mode, and the production efficiency of the floating body is improved. After the first preset time period has elapsed, it can be determined that the upper cover 2 has been completely cured.
And then, standing the first pouring template and the second pouring module for a period of time, and if the first pouring template and the second pouring module are placed in a standing state for a second preset time, determining that the temperatures of the upper cover 2 and the base 1 are reduced to normal temperature and the structure is stable. At this time, the first pouring template (i.e., the first pouring template positioned outside the base 1) and the second pouring template are removed, and the floating type floating body can be obtained.
Referring to fig. 2, there is shown another forming method of a floating type floating body according to an embodiment of the present invention, which may include:
s201, assembling a first pouring template on a table top of a vibration table, determining a first pouring cavity for forming the base 1, controlling the vibration table to vibrate according to a target frequency, and pouring active powder concrete into the first pouring cavity in a vibration process.
In the embodiment of the invention, the table top for assembling the first pouring template can be a table top of a vibration table, wherein the vibration table is an assembly table which can be driven by a vibration motor to vibrate. And assembling a first pouring template on the table top of the vibrating table to determine a first pouring cavity for forming the base 1. The first casting template may comprise a plurality of portions, and the first casting template of each portion may be removably secured. After the first pouring template is fixed, the vibrating table (namely a vibrating motor for driving the vibrating table to vibrate) can be controlled to vibrate according to the target frequency, and the active powder concrete is poured into the first pouring cavity in the vibrating process, so that the fact that the active powder concrete can be poured more uniformly in the pouring process can be guaranteed, the structural porosity among the active powder concrete is reduced, and the compactness of the base 1 is improved. In addition, the reactive powder concrete has better compressive strength and corrosion resistance, and can effectively reduce the weight of the reactive powder concrete. Thus, the foundation 1 made of the reactive powder concrete can be used for a long time in a corrosive environment such as a sea area for a long time, and the structural stability of the floating body can be improved while the buoyancy of the floating body is ensured. The target frequency may be greater than or equal to 2000r/min, and a person skilled in the art may determine the target frequency according to an actual application scenario, which is not limited herein.
In an optional invention embodiment, in order to ensure the buoyancy and structural stability of the floating body, the thickness in the first pouring cavity is in a range of 20-50mm, and the thickness in each position in the first pouring cavity is kept consistent. For example, the thickness may be 20mm, 30mm, 40mm, 50mm, and the like.
S202, under the condition that the pouring of the first pouring cavity is determined to be completed, stopping the vibration of the vibrating table, and carrying out steam curing on the active powder concrete in the first pouring cavity for a first preset time.
In the embodiment of the invention, when the reinforcing wall 3 or the side wall of the base 1 is fully poured with the active powder concrete, the first pouring cavity is determined to be completely poured, and the vibration of the vibrating table is stopped. And at the moment, steam curing is carried out on the active powder concrete in the first pouring cavity, so that the curing of the base 1 is accelerated in a steam heating mode, and the production efficiency of the floating body is improved. In the steam heating process, in consideration of heat loss, when the steam temperature is too low, the effect of improving the curing speed of the base 1 is not high, and when the steam temperature is too high, the curing speed of the base 1 can be quickly improved in a short time, so that the structural strength is reduced. Thus, in one example, steam curing corresponds to a steam temperature of 150-200℃, such as 150℃, 170℃, 190℃, and 200℃. After a first preset time, it may be determined that the base 1 is completely cured, and at this time, a portion of the first casting template located in the base 1 may be removed, so as to perform the next process.
The method may further comprise the step of determining a first preset duration:
and acquiring the target steam temperature and concrete parameter data of the steam curing.

In the embodiment of the present invention, the concrete parameter data is parameter data measured by the reactive powder concrete under a standard test condition (room temperature 25 ℃), the concrete parameter data includes a standard curing time, and the first preset time Ty may be calculated by the following formula (1):
in the formula (1), tb is a standard curing time; the Wd is a target steam temperature; rs is a temperature loss coefficient, which is determined in advance; the Rx is a temperature effect promotion coefficient which is obtained by pre-measurement. Wherein, the temperature loss coefficient refers to the energy efficiency coefficient of the steam temperature transmitted into the base 1. For example, when the temperature loss coefficient is 20%, which means that the steam temperature is 150 ℃, the corresponding temperature in the base 1 is 96 ℃; the temperature efficiency improvement coefficient refers to the improvement coefficient of the corresponding curing efficiency when the temperature is increased by 1 ℃. For example, when the temperature effect increase factor is 1%, it indicates that when the temperature is 1 ℃ higher per liter under standard test conditions, the corresponding curing efficiency is increased by 1%. Therefore, the efficiency of producing the floating body can be guaranteed when the first preset time is determined, the operations of directly carrying out template dismounting and the like on the base 1 which is not completely solidified can also be avoided, and the structural stability of the formed floating body is ensured.
S203, removing the first pouring template positioned in the base 1, and judging the pouring quality of the base 1 according to the cavity wall of the hollow cavity 4.
S204, under the condition that the pouring quality of the base 1 meets the preset repairing conditions, repairing the base 1 by adopting the reactive powder concrete.

In one example, when the cavity wall is uniform and has high flatness and no small groove, it is determined that the pouring quality of the base 1 does not meet the preset repair condition, and when a large groove, for example, a plurality of grooves with diameters exceeding 4cm, exists on the cavity wall, it is determined that the pouring quality of the base 1 meets the preset repair condition. And repairing the base 1 by adopting the reactive powder concrete until the pouring quality of the base 1 does not meet the preset repairing condition. The base 1 is repaired, so that the probability of local stress damage caused by the nonuniform structure of the base 1 can be reduced.
S205, after the repair is finished, a steel plate with two through holes is placed on the first pouring template to seal the two hollow cavities 4.
In the embodiment of the invention, after the inner wall of the base 1 is repaired, a steel plate with two through holes is placed on the first pouring template, and the steel plate is used for sealing the two hollow cavities 4. Wherein the shape of the steel plate also determines the shape of the foam filling 5 in the hollow cavity 4. Therefore, the two hollow cavities 4 closed by the steel plates are formed in a shape symmetrically disposed about the reinforcing wall 3. The structural stability of the floating body is guaranteed through the symmetrical structural design, and the situation that the local part is easy to break due to the fact that stress inside the base 1 is uneven can be avoided.
And S206, respectively injecting foaming materials into the two hollow cavities 4 through the two through holes for foaming, so that the two hollow cavities 4 are filled with the foaming filler 5.
In the embodiment of the present invention, each through hole is communicated with one hollow cavity 4, so that the foaming material can be injected into the two hollow cavities 4 through the two through holes respectively for on-site foaming. The person skilled in the art can select the foaming material to be foamed, and the method is not limited herein.
