Fig. 1 is a flowchart of a template control method for deep-sea ocean concrete floating island construction in the embodiment of the invention. Fig. 2 is a flow chart of a template control method for deep sea ocean concrete floating island construction in another embodiment of the invention. As shown in fig. 1 and 2, the method for controlling a formwork for constructing a deep ocean concrete floating island includes:
s101: and acquiring the inclination angle of the support rod piece from the angle detector and the draft of the template from the water depth detector.
Wherein, when the template is arranged in water, the template can be shaken under the action of wave force. Because the waves have periodicity, the shaking mainly takes the angular velocity and the angular acceleration of the template in the vertical direction as expression forms, and an angle detector and a water depth detector can be adopted to monitor the motion condition of the template at the moment. Because the template bears concreting such as concrete, construction equipment and personnel dead weight at the construction in-process, consequently the difference of total system maximum displacement and total system dead weight reduces, leads to the template draft to increase, acquires the whole draft data of template through the depth of water detector this moment, carries out draft through the vertical counter weight of template and adjusts.
S102: and sending an angle adjusting signal to the corresponding horizontal counterweight adjusting device according to the comparison result of the inclination angle of the support rod piece and the preset angle range, so that the horizontal counterweight adjusting device adjusts the corresponding template horizontal counterweight based on the angle adjusting signal.
Before executing S102, the method further includes: determining a balanced wave force according to the liquid density of the template, the liquid wave parameters and the template control system parameters; and determining the template horizontal counterweight according to the balance wave force, and ensuring that the moment of the maximum restoring force (namely the maximum self weight of the template horizontal counterweight) provided by the template horizontal counterweight to the center of gravity of the total system is greater than the moment of the balance wave force to the center of gravity of the total system.
In one embodiment, the liquid wave parameters comprise the height of the wave above the static water surface, the wave number of the sea area where the template is located and the wave height of the sea area, and the template control system parameters comprise the height of the underwater part of the template under the static water surface condition and the force arm of the horizontal counterweight of the template.
In specific implementation, by adopting the gravity wave theory, the wave force of the template unit on the wave-facing width is as follows:
wherein f (lambda) is the wave force borne by the template unit on the wave-facing width, rho is the seawater density (the density of the liquid where the template is located), and the unit is kg/m 3; g is the acceleration of gravity in m/s2(ii) a h is the height of the template under the water under the condition of water surface static, and the unit is m; λ is the height of the wave above the stationary water surface (the wave is negative below the stationary water surface), and is given in m; k is the wave number of the sea area where the template is located.
The force required to balance the maximum wave force (balance wave force) is therefore:
wherein H is the sea area wave height and the unit is m; l is the force arm of the horizontal counterweight of the template, and the unit is m. When in use
When the temperature of the water is higher than the set temperature,
when in use
When the temperature of the water is higher than the set temperature,
in one embodiment, the horizontal counterweight adjusting device is a water pump, and the template horizontal counterweight is a counterweight water tank; in this case, S102 includes:
and sending an angle adjusting signal to the corresponding water pump according to the comparison result of the inclination angle of the support rod piece and the preset angle range so that the water pump adjusts the corresponding counterweight water tank based on the angle adjusting signal.
During specific implementation, when the position of the angle detector is close to the first counterweight water tank and the inclination angle of the support rod is larger than a preset angle range (namely larger than the maximum value in the preset angle range), the first counterweight water tank is indicated to incline upwards (the template inclines upwards in the direction of the first counterweight water tank). And at the moment, the template control device sends an angle adjusting signal to the second water pump, and the second water pump pumps water in the second counterweight water tank into the first counterweight water tank according to the angle adjusting signal until the inclination angle of the support rod piece is smaller than or equal to the maximum value in the preset angle range.
When the position of the angle detector is close to the first counterweight water tank and the inclination angle of the support rod is smaller than a preset angle range (namely smaller than the minimum value in the preset angle range), the first counterweight water tank is indicated to be inclined downwards (the template is inclined downwards in the direction of the first counterweight water tank). At this time, the template control device 8 sends an angle adjusting signal to the first water pump, and the first water pump pumps water in the first counterweight water tank into the second counterweight water tank according to the angle adjusting signal until the inclination angle of the support rod piece is larger than or equal to the minimum value in the preset angle range.
When the position of the angle detector is close to the second counterweight water tank and the inclination angle of the support rod piece is larger than the preset angle range, the second counterweight water tank is indicated to incline upwards (the template inclines upwards in the direction of the second counterweight water tank). At the moment, the template control device sends an angle adjusting signal to the first water pump, and the first water pump pumps water in the first counterweight water tank into the second counterweight water tank according to the angle adjusting signal until the inclination angle of the support rod piece is smaller than or equal to the maximum value in the preset angle range.
When the position of the angle detector is close to the second counterweight water tank and the inclination angle of the support rod piece is smaller than the preset angle range, the second counterweight water tank is indicated to be inclined downwards (the template is inclined downwards in the direction of the second counterweight water tank). At the moment, the template control device sends an angle adjusting signal to the second water pump, and the second water pump pumps water in the second counterweight water tank into the first counterweight water tank according to the angle adjusting signal until the inclination angle of the support rod piece is larger than or equal to the minimum value in the preset angle range.
The water tank type counterweight adjustment is suitable for sea areas with standing waves as main parts.
Or the horizontal counterweight adjusting device is a chain transmission motor, and the horizontal counterweight of the template is a counterweight block; in this case, S102 includes:
and sending an angle adjusting signal to the corresponding chain transmission motor according to the comparison result of the inclination angle of the support rod piece and the preset angle range, so that the chain transmission motor can adjust the position of the balancing weight based on the angle adjusting signal.
The slider type adjustment is suitable for sea areas with high ocean current speed.
In summary, the angle of the entire template can be stabilized in S102.
S103: and sending a counterweight adjusting signal to the vertical counterweight adjusting device according to the comparison result of the template draft and the preset water depth range so that the vertical counterweight adjusting device adjusts the vertical counterweight of the template based on the counterweight adjusting signal.
In one embodiment, the vertical counterweight adjusting device is an air pump, and the template vertical counterweight is an air bag; at this time, S103 includes:
when the draft of the template is larger than the preset water depth range, sending a gas pumping signal to a gas pump so that the gas pump pumps gas (equivalent to a mounted floating body or a floating block) into the airbag based on the gas pumping signal; and when the template draft is smaller than the preset water depth range, sending an air pump-out signal to the air pump so that the air pump pumps out the air in the air bag based on the air pump-out signal. Control of the draft of the template can be achieved through S103.
The vertical counterweight adjusting device realizes draft stability by adjusting the difference between the maximum displacement of the total system (including a template and a template control system) and the dead weight of the total system. The draft is stable, namely the change of the draft of the total system in a preset range of the draft is ensured.
For example, the preset water depth range is [ -b meters, b meters ], and b should be determined according to the allowable variation of the draft of the template. The self weight of the template is increased in the construction process, and the draught depth is increased under the condition of the same maximum water discharge. If the difference between the maximum water displacement of the total system and the dead weight of the total system is small, the fact that most of the total system needs to sink into water to ensure self-floating is meant, and at the moment, the draft of the template is large. When the draft of the template is greater than b meters, the difference between the maximum water discharge of the total system (including the template and the template control system) and the dead weight of the total system needs to be increased, and at the moment, a gas pumping signal is sent to the gas pump, so that the gas pump pumps gas into the airbag based on the gas pumping signal, and the difference can be increased in a mode of increasing the maximum water discharge of the total system; when the draft of the template is less than-b meters, the difference between the maximum displacement of the total system and the dead weight of the total system needs to be reduced, and at the moment, an air pump-out signal is sent to the air pump, so that the air pump pumps out air in the air bag based on the air pump-out signal, and the difference can be reduced by reducing the maximum displacement of the total system.
The template vertical counterweight of the present invention may also be a series of counterweight blocks. When the template draft is greater than the preset depth range, the counterweight block can be removed to increase the difference between the maximum displacement of the total system and the dead weight of the total system by reducing the dead weight of the total system. When the template draft is less than the preset water depth range, the counterweight block can be added to reduce the difference between the maximum displacement of the total system and the dead weight of the total system by increasing the dead weight of the total system. The invention can also reduce the dead weight of the total system by draining water.
When the method is specifically implemented, the draft of the template can be adjusted by jointly using a mode of adjusting the self weight of the total system and the maximum water discharge of the total system.
The execution main body of the template control method for the construction of the deep ocean concrete floating island shown in fig. 1 is a controller. As can be seen from the flow shown in fig. 1, the template control method for deep-sea ocean concrete floating island construction according to the embodiment of the present invention sends an angle adjustment signal to a corresponding horizontal counterweight adjustment device according to the comparison result between the support rod inclination angle and the preset angle range, so that the horizontal counterweight adjustment device adjusts the corresponding horizontal counterweight of the template based on the angle adjustment signal, and sends a counterweight adjustment signal to a vertical counterweight adjustment device according to the comparison result between the template draft and the preset water depth range, so that the vertical counterweight adjustment device adjusts the vertical counterweight of the template based on the counterweight adjustment signal, thereby effectively stabilizing the floating template in the water construction, ensuring the stability of the water concrete construction, and improving the solidification effect of the concrete.
As shown in fig. 2, when the formwork is launched, the difference between the maximum displacement of the total system and the dead weight of the total system should be increased to realize self-floating of the formwork, and the self-weight of corresponding construction equipment and personnel can be borne. The horizontal stability guarantee time of the template is started from the beginning of a certain round of pouring, and the horizontal stability time is longer than the time required by the setting process of the used materials (such as concrete); the vertical stability of the template ensures that the time period should run through the whole construction process. And after the template is built and self-floating is realized, the template control system on the template is dismantled, and the next building cycle is started. When the template is built, measures for stopping water and slurry (for example, waterproof materials (such as glass cement) are adopted for sealing at the joints of the template) can be designed, and the water permeability of the splicing gaps of the template is reduced.
The specific process of the embodiment of the invention is as follows:
1. and setting a preset angle range and a preset water depth range.
2. And (4) building the template, and starting to construct on the template.
3. And controlling the draft of the template within a preset water depth range in the construction process until the construction is finished. And if the template draft is not within the preset water depth range, draft adjustment is carried out, the controller sends a counterweight adjustment signal to the vertical counterweight adjustment device, and the vertical counterweight adjustment device adjusts the vertical counterweight of the template based on the counterweight adjustment signal until the template draft is within the preset water depth range.
4. And judging whether the concrete material is condensed or not in the construction process. And when the concrete material is not coagulated, controlling the inclination angle of the support rod piece within a preset angle range until the concrete material is coagulated. If the inclination angle of the support rod piece is not controlled within the preset angle range, angle adjustment is carried out, the controller (the template control system) sends an angle adjustment signal to the corresponding horizontal counterweight adjusting device, and the corresponding horizontal counterweight adjusting device adjusts the corresponding template horizontal counterweight based on the angle adjustment signal until the inclination angle of the support rod piece is controlled within the preset angle range.
5. After the template is built, the template is launched into water and self-floating is realized, the controller on the template is dismantled, and the next building cycle is started.
