[0002] With the acceleration of urbanization, the number of super-high-rise building designs is increasing. The construction quality of the core load-bearing components, the giant columns, directly affects the overall performance of the building. The traditional concrete pouring method usually relies on manually controlled delivery pipelines or single chutes to complete the material distribution operation, which is inefficient and easily leads to serious concrete segregation. Although this traditional process has met the needs of small engineering projects to a certain extent, it has exposed many problems when facing the complex environment of super-high-rise buildings, especially in terms of high-precision material distribution and prevention of material separation.

[0003] Common concrete pouring methods mainly include open chute method and flat plate vibrator assisted method. The former builds a temporary inclined channel to allow the mixture to flow naturally to the designated area. The advantage is that the structure is simple and easy to operate, but there are obvious limitations, such as the inability to accurately control the flow distribution, which can easily cause local accumulation or even blockage risks; the latter uses mechanical equipment to generate high-frequency vibrations to force the slurry to fill the gaps to achieve a compacting effect. However, this method consumes a lot of energy and may cause noise pollution and other problems, which cannot meet the working requirements of concrete pouring applications. Therefore, a super-high-rise giant column material string tube structure and construction method are proposed. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides a technical solution, a super high-rise giant column material distribution string tube structure, including a main chute 1, a branch chute 2, a string card key 3, a hose 4, a support frame rod 5, a micro camera 6, a chute 7, a cut-off plate 8 and a motor drive device 9.

[0023] See also Figure 1 , the main chute 1 is installed on a giant column steel platform, please refer to Figure 4 The main chute 1 is welded with a sub-chute 2 on its surface, and an opening is installed on the top of the sub-chute 2. Figure 5, a chute 7 is provided on the inner side wall of the sub-chute 2, and the chute 7 is filled with lubricating liquid to ensure that the cut-off plate 8 can move smoothly and stably in the chute 7, so as to accurately control the flow rate of concrete, and a cut-off plate 8 is nested inside the chute 7, and a motor drive device 9 is installed at the outer end of the cut-off plate 8. The main chute 1 is made of high-strength alloy steel plate, and the thickness of the main chute 1 is 8mm-12mm. The inner surface of the main chute 1 is processed by high-precision polishing process. The main chute 1 made of this material is based on the fact that the main chute 1 needs to withstand huge concrete pressure and long-term wear in super-high-rise construction, so that the high-strength alloy steel plate has excellent compressive and wear resistance, which can ensure that it will not be deformed or damaged due to the impact and friction of concrete during long-term use. At the same time, the inner surface of the main chute 1 is processed by high-precision polishing process, which can reduce the resistance of concrete in the flow process, and ensure that the concrete can flow smoothly in the main chute 1, thereby improving the working efficiency of the entire material distribution string tube structure; The welding method of the main chute 1 and the branch chute 2 adopts a double-sided welding process, and the welding materials must correspond to the materials of the main chute 1 and the branch chute 2 to ensure the firmness of the welding. After the welding is completed, the welding parts need to be subjected to ultrasonic flaw detection to ensure that there are no internal defects in the welding parts, such as pores, slag inclusions, etc.; The outer periphery of the cut-off plate 8 is clamped with a rubber sealing gasket, a dust cover is installed on the outside of the motor drive device 9, and an overload protector is installed inside the motor drive device 9. The motor power of the motor drive device 9 should be matched according to the weight of the cut-off plate 8, the friction force to be overcome, and the speed requirement of moving in the slide 7. The added dust cover is to ensure that the motor drive device 9 can operate stably in a harsh construction environment, prevent concrete dust, water vapor, etc. from entering the motor and affecting the performance of the motor, and the overload protector installed inside the motor drive device 9 can automatically cut off the power supply when encountering unexpected resistance and causing the motor current to be too large, so as to avoid damage to the motor; The serial card key 3 is installed at the outlet of the sub-chute 2. The bottom outlet end of the serial card key 3 is connected to a hose 4 through a hard joint. The outer end of the hose 4 is connected to a support frame rod 5. The number of the support frame rods 5 is set to be equipped with a set of support frame rods 5 for every 3-5 meters of the hose 4. The structure of the support frame rod 5 is a spring telescopic rod, which can be adjusted in length according to the actual position and angle of the hose 4. The bottom of the support frame rod 5 should be fixed to the steel platform of the giant column with anchor bolts, and a flexible protective cover is installed at the contact part between the support frame rod 5 and the hose 4 to prevent the support frame rod 5 from causing wear to the hose 4; A micro camera 6 is installed outside the interface between the hose 4 and the serial card key 3. The resolution of the micro camera 6 is at least 1080P and has a wide dynamic range. It can clearly capture the situation at the interface between the hose 4 and the serial card key 3 under different lighting conditions. At the same time, the lens of the micro camera 6 adopts anti-fog and dust-proof design to ensure normal operation in harsh construction environments. The micro camera 6 is connected to the control system. The control system can receive the image data captured by the micro camera 6 in real time and analyze and process the image. For example, it can detect whether there is concrete leakage at the interface, whether the hose 4 is abnormally deformed, etc. through image recognition technology. When an abnormal situation is detected, the control system can promptly issue an alarm signal to remind the operator to check and handle it. The micro camera 6 is powered by low-voltage DC, and the power supply line is shielded to prevent electromagnetic interference from the construction site. The micro camera 6 is installed at the interface between the hose 4 and the serial card key 3 through an adjustable bracket on the tripod, so that when the micro camera 6 needs to be maintained or replaced, the operator can easily operate it without affecting the normal operation of the entire material string tube structure. The connection card key 3 is in the shape of a funnel, and the cone angle of the funnel of the connection card key 3 is 45 degrees-60 degrees. Such a cone angle can make the concrete transition smoothly when passing through the connection card key 3, reducing the splash and energy loss of concrete. The connection card key 3 and the outlet of the sub-chute 2 are connected by a bolt pipe clamp. The connection between the connection card key 3 and the outlet of the sub-chute 2 is clamped with a sealing gasket on the inner side. The hard joint at the connection between the connection card key 3 and the hose 4 is tapered. The connection between the connection card key 3 and the hose 4 is provided with multiple layers of rubber sealing rings and metal clamps. The hose 4 is a spring-retractable multi-layer composite structure. The inner layer of the hose 4 is a wear-resistant and corrosion-resistant rubber layer, the middle layer of the hose 4 is a reinforced fiber layer, and the outer layer of the hose 4 is a protective layer.

[0024] See also Figure 2 The method for constructing a super-high-rise giant column material string tube of the present invention comprises the following steps: S1 Preparation before construction; Check the main chute 1, including the scratches and deformation defects on the surface of the main chute 1. The main chute 1 is the main channel for concrete flow. The scratches and deformation defects on its surface may affect the smoothness of concrete flow. If there are scratches, it may cause resistance in the concrete flow process, and there may even be concrete residues at the scratches, which will gradually accumulate over time and affect the effective inner diameter of the chute. The deformation defects will change the flow direction of the concrete and cause uneven distribution of the concrete. Therefore, by carefully inspecting the surface of the main chute 1, these potential problems can be discovered in advance, and repair or replacement measures can be taken to ensure that the concrete can flow in an ideal chute environment, thereby ensuring the stability of concrete supply during the entire construction process. Then check the branch chute 2 to check the integrity of its opening and chute 7 structure, check the cut-off plate 8 to ensure that the rubber sealing gasket clamped on its periphery is firmly installed and well sealed, check the motor drive device 9 to confirm that the external dust cover is installed in place and the internal overload protector is functioning normally, and activate the control system of the operating equipment, while integrating the Internet of Things communication module and the data acquisition module inside the control system; S2 hardware assembly; Assemble the chute frames of each level in sequence according to the positions marked on the drawing and lock them with fasteners. Connect the distribution chute 2 with the through key 3, the through key 3 and the hose 4. Install a flow rate sensor and an intelligent controller inside the main chute 1. The good connection between the distribution chute 2 and the through key 3, as well as the through key 3 and the hose 4, is the key to ensuring the smooth transition of concrete between different components. If the connection is not good, leakage or blockage is likely to occur during the flow of concrete. Since the flow rate sensor and the intelligent controller are installed inside the main chute 1, the flow rate sensor can monitor the flow rate of concrete in real time, and the intelligent controller can perform intelligent control based on the flow rate data. The specific method of intelligent control is as follows: First, preset an ideal flow rate range of concrete in the intelligent controller, that is, V1 - V2. During the pouring process, the flow rate sensor collects the flow rate data V of concrete in real time. After receiving this data, the intelligent controller compares it with the preset flow rate range. If V < V1, it means that the flow rate of concrete is too slow. At this time, the intelligent controller calculates the adjustment amount of the opening degree of the cut-off plate 8 according to the proportional relationship. If V > V2, that is, the flow rate of concrete is too fast, it is adjusted according to the proportion. After the intelligent controller adjusts the opening degree of the cut-off plate 8, it continuously collects new flow rate data through the flow rate sensor and repeats the above comparison and adjustment process continuously to form a dynamic feedback control loop until the flow rate stabilizes within the preset ideal flow rate range. This range is determined according to the technological requirements of the concrete placing construction of super high-rise mega-columns. Such an installation layout makes the monitoring and control of the flow rate of concrete more direct and effective, and can adjust the flow state of concrete in time to meet the construction requirements. At the same time, install a fault diagnosis sensor and a fault diagnosis and repair controller inside the motor drive device 9, the flow rate sensor, the intelligent controller and the micro camera 6. Installing a fault diagnosis sensor and a fault diagnosis and repair controller inside these key devices can monitor the running state of the devices in real time and diagnose faults, enabling the fault diagnosis sensor to collect data such as temperature, vibration and circuit state during the operation of the devices. Once these data are abnormal, the fault diagnosis and repair controller can analyze and process them in time. The analysis logic of the fault diagnosis and repair controller is as follows: The fault diagnosis and repair controller collects data such as temperature, vibration and circuit state during the operation of key devices such as the motor drive device 9, the flow rate sensor, the intelligent controller and the micro camera 6 through the fault diagnosis sensor. Then, for the received device running state data, the fault diagnosis and repair controller first judges the data validity. For example, for temperature data, if it exceeds the normal operating temperature range of the device or the data fluctuates abnormally, it may be judged as invalid data. Similarly, for vibration data, if the vibration frequency or amplitude suddenly changes abnormally and does not conform to the fluctuation range in the normal operating mode of the device, it may also be judged as invalid data.If the circuit status data shows values ​​that do not conform to normal logic, such as short circuit or open circuit, it will also be regarded as invalid data. For each device, a normal temperature operating range is preset in the fault diagnosis and repair controller.

[0025] The repair measures for the fault analysis of the fault diagnosis and repair controller are that the fault diagnosis and repair controller takes cooling measures when it detects that the device temperature is too high. For example, for devices with cooling fans, the speed of the cooling fan can be increased. If the micro camera 6 vibrates abnormally, the fault diagnosis and repair controller first determines whether it is an installation problem. If the installation is not firm, an instruction may be issued to remind the operator to reinstall or reinforce the installation components. If the internal parts are loose, for some simple structures, such as self-tightening screws, the fault diagnosis and repair controller may try to issue instructions for automatic tightening; for complex structures, an alarm will be issued to remind the operator to check and repair. Finally, for circuit faults, such as short circuits or open circuits, in some simple circuit faults such as poor line contact, the fault diagnosis and repair controller can try to perform self-repair, such as reconnecting the disconnected line by controlling the relay or eliminating the short circuit point if the short circuit is caused by a simple metal foreign body. For more complex problems such as circuit component damage, the fault diagnosis and repair controller will send out an alarm signal to notify the operator to replace components or perform more in-depth circuit repairs. For some simple faults, such as overtemperature, cooling measures can be taken, and circuit faults can be self-repaired, which helps to improve the reliability of equipment, reduce the impact of equipment failures on construction, and ensure the continuity of construction; S3 formal construction operation; See also Figure 3 , S31 start-up and feeding: Start the motor drive device 9 of the stop plate 8, adjust the stop plate 8 to the initial position, open the concrete feed valve, and let the concrete flow into the main chute 1. Start the motor drive device 9 and adjust the stop plate 8 to the initial position to control the initial state of the concrete entering the main chute 1. The accurate setting of the initial position of the stop plate 8 can accurately control the initial flow of the concrete to avoid the situation where the flow is too large or too small at the beginning. After opening the feed valve, the concrete flows smoothly into the main chute 1. The smooth progress of this process is the beginning of the entire construction operation. If there is a problem in this step, such as the motor drive device 9 cannot be started normally or the stop plate 8 is not in the correct position, it may cause the concrete to be unable to enter the main chute 1 normally, thereby affecting the pouring progress of the entire giant column; S32 Flow Control: According to the construction requirements, the motor drive device 9 is operated by the control system to adjust the opening of the cut-off plate 8, so as to control the flow of concrete in the sub-chute 2. At the same time, the image captured by the micro camera 6 is used to observe the situation at the interface between the hose 4 and the serial key 3 to ensure that the concrete passes through the entire material distribution string tube structure smoothly and enters the predetermined position in the giant column. The opening of the cut-off plate 8 is adjusted by accurately operating the motor drive device 9 by the control system, so that the precise control of the concrete flow can be achieved. Since different parts require different concrete flow rates to ensure the density and uniformity of pouring, such precise control is crucial to the pouring quality of different parts of the giant column. At the same time, the observation of the interface between the hose 4 and the serial key 3 by the micro camera 6 can timely detect whether there is concrete blockage, leakage or deformation of the hose 4 at the interface. If a problem is found, it can be adjusted in time to ensure that the concrete can pass through the entire material distribution string tube structure smoothly to reach the predetermined position, so as to avoid the failure of the entire pouring or the quality of the giant column due to local problems. S33 construction process monitoring: During the concrete pouring process, the running state of the motor drive device 9, the position of the cut-off plate 8, the expansion and contraction of the hose 4 and the interface conditions photographed by the micro camera 6 are continuously monitored. The surface of the hose 4 is affixed with a strain gauge. Since the surface of the hose 4 is affixed with a strain gauge, the strain of the hose 4 can be accurately measured. Once the strain exceeds the normal range, it may indicate that the hose 4 is subjected to abnormal pressure or is about to be damaged. Timely discovery can avoid serious problems such as concrete leakage, and the monitoring of the interface conditions photographed by the micro camera 6 can detect subtle changes in the interface, such as whether the seal is good or not. At the same time, the flow velocity sensor transmits the detected flow velocity data to the intelligent controller in real time. The intelligent controller compares the received flow velocity data with the preset flow velocity value, and then sends a signal to the motor drive device 9 of the cut-off plate 8 to control the opening of the cut-off plate 8. At the same time, when the flow velocity sensor transmits the detected flow velocity data to the intelligent controller in real time, a redundant collection and transmission method is adopted, that is, at least two flow velocity sensors are installed at the same position, and each flow velocity sensor collects flow velocity data at a different frequency, and then transmits it to the intelligent controller at the same time. After receiving the two sets of flow velocity data, the intelligent controller first judges the validity of the data, removes abnormal data points, and adopts a weighted average method to fuse the data judged to be valid; During the pouring process, the data acquisition module transmits the collected data to the Internet of Things communication module, and the Internet of Things communication module sends the received data to the server of the remote monitoring center through the network. When the data acquisition module transmits the data to the Internet of Things communication module, the AES symmetric encryption algorithm is used, and the encryption key length is 128 bits; The fault diagnosis sensor inside the equipment transmits the collected equipment operation status data including temperature, vibration and circuit status to the fault diagnosis and repair controller in real time, and the fault diagnosis and repair controller analyzes and processes the received data. When the fault diagnosis sensor transmits the equipment operation status data to the fault diagnosis and repair controller, a dual-channel transmission line is used, one channel is a main transmission line, and the other channel is a backup transmission line, and a signal repeater is set on the transmission line; S34 construction end operation: When the concrete pouring task is completed, the feed valve is closed, the motor drive device 9 is stopped, and the concrete remaining in the material distribution string tube structure is cleaned up. The various components are inspected and maintained to prepare for the next construction. Closing the feed valve and stopping the motor drive device 9 are necessary operations at the end of the construction, which can prevent the concrete from continuing to flow into the material distribution string tube structure, avoiding unnecessary waste and cleaning difficulties. It is very important to clean the residual concrete in the material distribution string tube structure. If the residual concrete is not cleaned up in time, it may solidify and harden in the chute, affecting the flow of concrete during the next construction, and may even damage the inner surface of the chute. By inspecting and maintaining various components, it is possible to timely discover problems such as wear and damage that may occur in the components during the construction process, such as whether the parts of the motor drive device 9 are loose, whether the chute is deformed, etc. Through timely repair and maintenance, the service life of the components can be extended to ensure that all components can work normally during the next construction. In step S32, the image captured by the micro camera 6 can be used to observe the situation at the interface between the hose 4 and the serial key 3, ensuring that the concrete passes through the entire material distribution string tube structure smoothly and enters the predetermined position in the giant column. Through real-time observation of the interface, it is possible to promptly detect whether there is concrete blockage, leakage or deformation of the hose 4 at the interface. If a problem is found, timely adjustments can be made to ensure that the concrete can smoothly pass through the entire material distribution tube structure to reach the predetermined position, thereby avoiding failure of the entire pouring or quality problems of the giant column due to local problems. In step S33, the micro camera 6 continuously shoots the situation at the interface and can detect subtle changes in the interface, such as whether the seal is good, etc., providing important visual monitoring information for the smooth progress of the entire construction process.

[0026] This solution can effectively control the flow path of concrete by driving the opening of the stop plate 8 through the motor drive device 9, reduce the material separation of concrete, and achieve high controllability of concrete distribution. At the same time, the intelligent control of the opening and closing of the stop plate 8 greatly improves the pouring accuracy, enhances the quality consistency of concrete, and improves the safety and durability of the final structure. At the same time, through the cooperation of the flow rate sensor and the intelligent controller, the opening of the stop plate 8 can be adjusted in real time according to the construction requirements to control the concrete flow, thereby improving the accuracy and efficiency of concrete pouring. In addition, during the construction process, the data acquisition module and the Internet of Things communication module can transmit the equipment operation data to the remote monitoring center in time, which is convenient for construction personnel to grasp the construction situation in time and adjust the construction strategy in time, thereby improving the overall construction efficiency.

[0027] This solution also monitors the flow rate through multi-sensor redundancy, so that in terms of flow rate monitoring, a redundant acquisition and transmission method is adopted, that is, at least two flow rate sensors are installed at the same position, and each flow rate sensor collects flow rate data at different frequencies, and then transmits it to the intelligent controller at the same time. This method improves the accuracy of flow rate data, and in the construction process, the flow rate control of concrete is crucial to the construction accuracy. Traditional single sensors may cause inaccurate flow rate data due to factors such as their own failures and external interference. Multi-sensor redundancy can use the intelligent controller to judge the effectiveness of two sets of data, eliminate abnormal data points, and use the weighted average method to fuse the effective data. In this way, data closer to the actual flow rate can be obtained, so as to more accurately control the opening of the cutoff plate 8, ensure that the flow rate of concrete in the chute 2 meets the construction requirements, and improve the compactness and uniformity of the pouring of different parts of the giant column. At the same time, the Internet of Things remote monitoring transmits the collected equipment operation status data including temperature, vibration and circuit status to the fault diagnosis and repair controller in real time through the fault diagnosis sensor inside the equipment, and then transmits it to the server of the remote monitoring center. This enables the equipment status during the construction process to be monitored in real time. For example, during the operation of the motor drive device 9, if the temperature is too high or the vibration is abnormal, the remote monitoring center can detect and take measures in time. For some simple faults, the fault diagnosis and repair controller can automatically handle them to avoid the impact of equipment failure on construction, ensure the continuity of construction, and indirectly improve the construction accuracy. In addition, the Internet of Things remote monitoring can receive the image data of the interface between the hose 4 and the serial key 3 taken by the micro camera 6, the flow rate data of the flow rate sensor, and the equipment operation status data in real time. Through the comprehensive analysis of these data, the remote monitoring center can fully understand all aspects of the construction process. For example, if the micro camera 6 finds that there is concrete leakage or deformation of the hose 4 at the interface between the serial key 3, the remote monitoring center can promptly notify the on-site operator to make adjustments to avoid the problem from expanding and affecting the construction accuracy.
