Description

Technical Field

[0001] This application generally relates to the technical field of diaphragm wall pouring, and specifically relates to a diaphragm wall pouring construction platform and its usage method. Background Art

[0002] In the construction of diaphragm wall concrete pouring, the traditional process requires accurately lowering the concrete conduit to the underground design elevation, and then connecting the funnel at the top of the concrete conduit with the discharge port of the concrete tanker to achieve the directional transportation of concrete. As the pouring process progresses, the concrete surface in the trench hole continuously rises. When the bottom of the conduit is completely buried by the concrete, the concrete in the conduit is prone to a sudden decrease in flow velocity or even blockage due to the increased fluid resistance. Once a blockage occurs, the concrete in the funnel cannot flow down normally, and then overflows. The current adjustment method is to start the hoisting equipment, first remove the funnel as a whole, then use a special hook device to hang the conduit on the hook, lift the conduit by 0.5 - 1 meter through mechanical lifting, and then release the hook to make the conduit freely fall under the action of gravity and collide with the bottom support. The internal blockage of the conduit is broken by using the instantaneous inertial force, so that the pouring operation can continue.

[0003] However, in practical applications, the conduit is frequently blocked. This traditional adjustment method not only requires manual cooperation, has a high operation risk and strong randomness, and there is no standardized method to eliminate blockages, but also the existing concrete conduit derrick structure is not easy to hoist and install. Therefore, we propose a diaphragm wall pouring construction platform and its usage method to solve the above problems. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a diaphragm wall pouring construction platform and its usage method that can reduce the occurrence probability of conduit blanking blockage, improve construction efficiency, and have high safety and reliability.

[0005] In a first aspect, this application provides a diaphragm wall pouring construction platform, including: A support assembly, the support assembly includes a support chassis and a guide rail arranged on the support chassis. The support chassis is used to be placed on the foundation on the top surface of the pouring trench hole. The guide rail is located on the side away from the pouring trench hole, and the extending direction of the guide rail is perpendicular to the support chassis; A bracket assembly, the bracket assembly has a chute slidably connected to the guide rail; a cover plate structure is hinged on the bracket assembly. The cover plate structure includes a pair of movable cover plates used in cooperation, and at adjacent positions of the two movable cover plates, grooves with opposite openings are provided, and the two grooves form an installation through hole for accommodating the conduit to pass through; A push-pull assembly, which is in driving connection with the bracket assembly; the push-pull assembly includes a driving structure arranged on the support chassis and a movable push plate slidably connected to the support chassis, and a driving shaft of the driving structure is connected to one side of the movable push plate; When the conduit is clamped at the installation through-hole, the driving shaft of the driving structure drives the movable push plate to reciprocate along the length direction of the support chassis, thereby driving the bracket assembly to reciprocate along the guide rail, so that the bracket assembly collides with the support chassis at a preset frequency, thereby assisting the conduit to discharge materials into the pouring slot hole during the construction process.

[0006] According to the technical solution provided by the embodiment of the present application, the bracket assembly includes: a bracket body, a cover plate structure is hinged to one side of the bracket body, and two groups of push rod structures are rotatably connected to the other side thereof, and each group of push rod structures has multiple movable push rods; A travel groove equal in number to the movable push rods is formed on one side of the movable push plate away from the support chassis; the free end of the movable push rod is slidably connected to the corresponding travel groove; When the driving shaft of the driving structure drives the movable push plate to reciprocate along the length direction of the support chassis, the movable push rod slides in the travel groove, thereby jacking up or pulling back the bracket body, so that the bracket assembly reciprocates along the guide rail.

[0007] According to the technical solution provided by the embodiment of the present application, an installation groove is formed on the support chassis along its length direction, and a plurality of rollers rotatably connected to its inner wall are arranged in the installation groove; the central axis of the roller is parallel to the width direction of the support chassis, and the roller is in rolling contact with the bottom surface of the movable push plate.

[0008] According to the technical solution provided by the embodiment of the present application, it further includes: a snap ring arranged on the conduit; When the conduit extends into the pouring slot hole through the installation through-hole, the snap ring is clamped with the edge of the installation through-hole.

[0009] According to the technical solution provided by the embodiment of the present application, it further includes: A control unit, the control unit is in communication connection with the driving structure, and the control unit is used to control the working state of the driving structure.

[0010] According to the technical solution provided by the embodiment of the present application, protective plates are arranged on the edges of the bracket body and the support chassis, and a lifting lug is arranged at one end of the guide rail away from the support chassis.

[0011] According to the technical solution provided by the embodiment of the present application, a hollow area communicating with the installation through-hole is provided on the bracket main body, and the area of the hollow area of the bracket main body is smaller than the area of the cover plate structure.

[0012] In a second aspect, the present application provides a method for using a construction platform for diaphragm wall pouring, which is implemented based on the above-mentioned construction platform for diaphragm wall pouring. The method includes the following steps: Place the support chassis on the foundation on the top surface of the pouring slot hole, open the movable cover plate of the cover plate structure, pass the conduit through the installation through-hole, make the snap ring engage with the edge of the installation through-hole, and close the movable cover plate; Perform the pouring operation and collect the concrete feeding information in real time. If it is recognized that the concrete in the concrete feeding information accumulates, use the drive shaft of the drive structure to drive the movable push plate to reciprocate along the length direction of the support chassis. The movable push rod slides in the stroke slot, and at the same time drives the support assembly to reciprocate along the guide rail, so that the support assembly collides with the support chassis at a preset frequency to assist the conduit in discharging materials into the pouring slot hole; When the concrete in the concrete feeding information does not accumulate, stop the operation of the drive structure, continue to perform the pouring operation, after the pouring is completed, turn off the control unit, open the movable cover plate, remove the conduit, and clean the concrete residue on the surface of the construction platform, and inspect and maintain the equipment.

[0013] According to the technical solution provided by the embodiment of the present application, after assisting the conduit in discharging materials into the pouring slot hole and before the pouring is completed, the following steps are further included: Real-time detect the concrete feeding speed; If the feeding speed is lower than the preset speed value, stop the construction, and check whether the conduit is blocked, whether the reciprocating frequency of the drive structure is appropriate, and monitor the collision situation between the support assembly and the support chassis.

[0014] According to the technical solution provided by the embodiment of the present application, after assisting the conduit in discharging materials into the pouring slot hole and before the pouring is completed, the following steps are further included: Real-time collect the image information of the concrete feeding and pouring conditions; and analyze the collected image information to identify the flow state of the concrete, whether there is segregation phenomenon and the flatness of the pouring surface; If the concrete is segregated or the pouring surface is uneven, use the control unit to adjust the running speed of the drive structure.

[0015] It can be seen from the above technical solutions that the present application has at least the following beneficial effects: The present application provides an anti-seepage wall pouring construction platform, comprising: a support assembly, which comprises a support base frame and a guide rail arranged on the support base frame, the support base frame is used to be placed on the foundation of the top surface of the pouring slot hole, the guide rail is located on a side away from the pouring slot hole, and the extension direction of the guide rail is arranged perpendicular to the support base frame; a bracket assembly, the bracket assembly has a slide groove slidably connected to the guide rail; a cover plate structure is hinged on the bracket assembly, the cover plate structure comprises a pair of movable cover plates for use in conjunction, and the two movable cover plates are provided with grooves with openings arranged opposite to each other at adjacent positions, and the two grooves form a mounting through hole for accommodating a conduit to pass through; a push-pull assembly, which is transmission-connected with the bracket assembly; the push-pull assembly comprises a driving structure arranged on the support base frame and a movable push plate slidably connected to the support base frame, and the driving shaft of the driving structure is connected to one side of the movable push plate; when the conduit is clamped at the mounting through hole, the driving shaft of the driving structure drives the movable push plate to reciprocate along the length direction of the support base frame, thereby driving the bracket assembly to reciprocate along the guide rail, so that the bracket assembly and the support base frame collide with each other at a preset frequency, thereby assisting the conduit to discharge materials into the pouring slot hole during the construction process.

[0016] The present application uses the installation through hole formed by the grooves of the two movable cover plates to accommodate the conduit to pass through and be lowered into the casting slot hole, and then uses the clamping relationship between the clamping ring and the edge of the installation through hole to limit the installation position of the conduit, thereby ensuring the stability of the conduit during the casting process. In addition, the driving structure is used to drive the movable push plate and the bracket assembly to reciprocate, so that the bracket assembly collides with the supporting base frame and generates vibration. This vibration will be transmitted to the conduit through the cover plate structure and the clamping ring, causing the conduit to oscillate. This oscillation acts on the concrete in the conduit, destroying its internal friction and cohesion structure, effectively reducing the friction between the concrete and the inner wall of the conduit, and changing the fluidity of the concrete, thereby assisting the discharge of the conduit, and preventing the problem of poor discharge caused by conduit blockage in advance, avoiding the cumbersome operation of using a crane to remove the funnel and lift the conduit every time it is blocked in the traditional method, greatly shortening the time for handling blockage, accelerating the concrete pouring speed, and thus significantly improving the construction efficiency. In addition, in traditional construction, when the crane lifts the conduit, the operator needs to hook and unhook at high altitude, which poses a risk of falling; at the same time, improper coordination between the crane and other construction machinery can easily cause collision accidents. However, this construction platform does not require the assistance of a crane to unload the material. It assists in unloading the conduit through its own self-excited vibration function, avoiding the intervention of the crane, eliminating the safety hazards caused by these high-altitude operations and mechanical coordination, reducing the safety risks during the construction process, and ensuring the safety of the lives of construction workers.

[0024] The following further elaborates on the present application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for the sake of convenience in description, only the parts related to the invention are shown in the drawings.

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will elaborate on the present application in detail with reference to the accompanying drawings and embodiments.

[0026] As Figure 1 and Figure 2 shown, the present application provides a construction platform for pouring an impervious wall, including: A support assembly 4, the support assembly 4 includes a support chassis 41 and a guide rail 44 provided on the support chassis 41. The support chassis 41 is used to be placed on the foundation on the top surface of the pouring slot hole, the guide rail 44 is located on the side away from the pouring slot hole, and the extending direction of the guide rail 44 is perpendicular to the support chassis 41; A bracket assembly 2, the bracket assembly 2 has a chute slidably connected to the guide rail 44; a cover structure 1 is hinged on the bracket assembly 2. The cover structure 1 includes a pair of cooperating movable covers 11, and at the adjacent positions of the two movable covers 11, grooves with opposite openings are provided, and the two grooves form an installation through hole 13 for accommodating the penetration of the conduit; The push-pull assembly 3 is drivingly connected to the support assembly 2; the push-pull assembly 3 includes a driving structure 32 disposed on the support chassis 41 and a movable push plate 31 slidably connected to the support chassis 41, and the drive shaft of the driving structure 32 is connected to one side of the movable push plate 31; When the conduit is clamped at the installation through-hole 13, the drive shaft of the driving structure 32 drives the movable push plate 31 to reciprocate along the length direction of the support chassis 41, thereby driving the support assembly 2 to reciprocate along the guide rail 44, so that the support assembly 2 collides with the support chassis 41 at a preset frequency, thereby assisting the conduit to discharge materials into the pouring slot hole during the construction process.

[0027] It should be noted that the support chassis 41 serves as the load-bearing foundation of the entire construction platform. Its material is, for example, heavy I-beam, with strong bearing capacity and integrity, and is easy to install. Before construction, the support chassis 41 is placed on the foundation on the top surface of the pouring slot hole to provide stable support for other components; the guide rail 44 is located on the side away from the pouring slot hole, and its extending direction is perpendicular to the support chassis 41. The material of the guide rail 44 is, for example, channel steel or I-beam, with strong bearing capacity and integrity, and is easy to install. The guide rail 44 provides a sliding track for the support assembly 2, enabling the support assembly 2 to reciprocate on the support chassis 41 along the guide rail 44.

[0028] The support assembly 2 has a chute slidably connected to the guide rail 44, enabling the support assembly 2 to stably reciprocate under the constraint of the guide rail 44. Moreover, a cover plate structure 1 is hinged to the support assembly 2. The cover plate structure 1 consists of a pair of movable cover plates 11 used in cooperation. Here, on the sides of the two movable cover plates 11 away from each other, there are shaft holes, and the shaft holes are rotatably connected to the support assembly 2 through the cover plate connecting shaft 12, enabling the two movable cover plates 11 to rotate around the cover plate connecting shaft 12, that is, to open or close the two movable cover plates 11. Oppositely arranged grooves are formed at adjacent positions of the two movable cover plates 11, and the two grooves form the installation through-hole 13. The conduit can pass through the installation through-hole 13. Additionally, a snap ring is provided on the conduit. When the conduit extends into the pouring slot hole through the installation through-hole 13, the movable cover plates 11 are closed, so that the snap ring is clamped with the edge of the installation through-hole 13, thereby playing a certain fixing role for the conduit and also preventing foreign objects from falling into the pouring slot hole during the construction process. Here, the material of the movable cover plate 11 is, for example, thick steel plate. The connection method between the snap ring and the conduit is, for example, welding or bolt connection. If it is welded, the welding quality should be ensured to prevent false welding; if it is bolted, high-strength bolts should be used, and corresponding nuts and washers should be equipped to ensure firm connection.

[0029] The driving structure 32 is arranged on the supporting chassis 41. Here, the driving structure 32 can be an electric push rod, a hydraulic cylinder, etc., which can be selected according to actual requirements. The driving shaft of the driving structure 32 is connected to one side of the movable push plate 31. The movable push plate 31 is slidably connected to the supporting chassis 41, and a number of stroke grooves 33 equal to the number of movable push rods 22 are provided on the side away from the supporting chassis 41. When the driving structure 32 is started, its driving shaft drives the movable push plate 31 to reciprocate along the length direction of the supporting chassis 41, driving the bracket assembly 2 to reciprocate along the guide rail 44.

[0030] The driving shaft of the driving structure 32 drives the movable push plate 31 to reciprocate along the length direction of the supporting chassis 41. At this time, it can drive the bracket assembly 2 to reciprocate along the guide rail 44, causing the bracket assembly 2 to collide with the supporting chassis 41 at a preset frequency. The vibration generated by this collision will be transmitted to the conduit through the cover plate structure 1 and the snap ring on the conduit, destroying the frictional force and cohesion structure of the concrete in the conduit, reducing the frictional force between the concrete and the inner wall of the conduit, changing the fluidity of the concrete, thereby assisting the conduit to discharge materials into the pouring slot hole, effectively preventing the conduit from being blocked and improving the construction efficiency. Here, the preset frequency refers to the number of collisions between the bracket assembly 2 and the supporting chassis 41 preset according to the actual construction requirements.

[0031] This platform can become a part of the standard equipment for underground impervious wall construction, making the pouring method more perfect and standard.

[0032] Furthermore, as Figure 1 and Figure 2 shown, the bracket assembly 2 includes: a bracket body 21. One side of the bracket body 21 is hinged with a cover plate structure 1, and the other side is rotatably connected with two groups of push rod structures. Each group of push rod structures has a plurality of movable push rods 22; A number of stroke grooves 33 equal to the number of movable push rods 22 are provided on the side of the movable push plate 31 away from the supporting chassis 41; the free ends of the movable push rods 22 are slidably connected to the corresponding stroke grooves 33; When the driving shaft of the driving structure 32 drives the movable push plate 31 to reciprocate along the length direction of the supporting chassis 41, the movable push rods 22 slide in the stroke grooves 33, and then jack up or pull back the bracket body 21, so that the bracket assembly 2 reciprocates along the guide rail 44.

[0033] It should be noted that one side of the bracket body 21 is hinged with the cover plate structure 1, and the other side is rotatably connected with the push rod structure. This design enables the bracket body 21 to organically combine the functions of the cover plate structure 1 and the push-pull assembly 3, realizing the coordinated work of the entire construction platform.

[0034] Each set of push rod structures includes multiple movable push rods 22. The movable push rods 22 are rotatably connected to the support body 21, enabling the movable push rods 22 to rotate relative to the support body 21. Here, the end of the movable push rod 22 can be connected to the support body 21 through a pin 23, and the movable push rod 22 can rotate around the pin 23, thereby changing the included angle between the movable push rod 22 and the support body 21. The opening of this included angle is not restricted.

[0035] On the side of the movable push plate 31 away from the support chassis 41, there are travel grooves 33 equal in number to the movable push rods 22. The function of the travel grooves 33 is to provide a sliding track for the free ends of the movable push rods 22. This sliding connection method enables the movable push rods 22 to slide freely within the travel grooves 33. When the movable push plate 31 moves, the free ends of the movable push rods 22 slide within the travel grooves 33, thereby changing their own positions, causing the included angle between the movable push rods 22 and the support body 21 to change, and thus realizing the pushing or pulling of the support body 21.

[0036] When the driving structure 32 is started, its drive shaft drives the movable push plate 31 to perform a reciprocating motion along the length direction of the support chassis 41. With the reciprocating motion of the movable push plate 31, the free ends of the movable push rods 22 slide within the travel grooves 33. Since the shape and position of the travel grooves 33 are fixed, the connection angle between the movable push rods 22 and the support body 21 will change during the sliding process. Therefore, when the movable push rods 22 slide within the travel grooves 33, forces in different directions will be generated, thereby jacking up or pulling back the support body 21. For example, when the movable push plate 31 moves in a direction away from the driving structure 32, the movable push rods 22 will gradually tilt, generating an upward or forward component force, thereby jacking up the support body 21; after the movable push rods 22 completely jack up the support body 21, the movable push plate 31 moves in the reverse direction, and the movable push rods 22 will generate a downward or backward component force, pulling back the support body 21; and, since the support assembly 2 is slidably connected to the guide rail 44 through a chute, when the support body 21 is jacked up or pulled back, the support assembly 2 will, under the constraint of the guide rail 44, perform a reciprocating motion along the guide rail 44. This reciprocating motion can cause the support assembly 2 to collide with the support chassis 41, and the vibration generated by the collision will be transmitted to the conduit, assisting the conduit to discharge materials into the pouring tank hole.

[0037] Furthermore, as Figure 3 shown, the support chassis 41 is provided with mounting grooves arranged along its length direction, and multiple rollers 43 rotatably connected to its inner wall are arranged in the mounting grooves; the central axis of the rollers 43 is parallel to the width direction of the support chassis 41, and the rollers 43 are in rolling contact with the bottom surface of the movable push plate 31.

[0038] It should be noted that an installation groove is provided on the support chassis 41 along its length direction. The main function of the installation groove is to provide an installation position and a support structure for the roller 43. The installation groove is opened along the length direction of the support chassis 41, enabling the rollers 43 to be arranged in a specific direction and providing guidance for the movement of the movable push plate 31. At the same time, the design of the installation groove also ensures the stability of the roller 43, preventing it from shifting or shaking during operation.

[0039] A plurality of rollers 43 rotatably connected to its inner wall are arranged in the installation groove. Each roller 43 can rotate freely in the installation groove. The roller 43 is in rolling contact with the bottom surface of the movable push plate 31. When the driving structure 32 drives the movable push plate 31 to reciprocate along the length direction of the support chassis 41, the bottom surface of the movable push plate 31 rolls on the roller 43. Compared with the movable push plate 31 sliding directly on the support chassis 41, this rolling contact method greatly reduces the frictional force, making the movement of the movable push plate 31 smoother and reducing energy loss. At the same time, the rolling contact can also reduce the wear between the movable push plate 31 and the support chassis 41, extending the service life of the equipment. In actual operation, this design allows the movable push plate 31 to achieve fast and stable reciprocating movement under a small driving force, improving the working efficiency and reliability of the construction platform. Moreover, the central axis of the roller 43 is arranged parallel to the width direction of the support chassis 41 to ensure that the roller 43 can evenly support the bottom surface of the movable push plate 31 during rolling, avoiding uneven local stress and ensuring the smooth movement of the movable push plate 31. Here, the material of the roller 43 can be selected as wear-resistant cast iron or alloy steel, and the surface is quenched to improve wear resistance. In addition, the roller 43 can be rotatably connected to the installation groove through a pin shaft 42.

[0040] Furthermore, as Figure 4 shown, it further includes: a control unit 7. The control unit 7 is communicatively connected to the driving structure 32, and the control unit 7 is used to control the working state of the driving structure 32.

[0041] It should be noted that the control unit 7 is communicatively connected to the driving structure 32 and is used to send various instructions to the driving structure 32, thereby controlling the working state of the driving structure 32, so that the rear support assembly 2 collides with the support chassis 41, aiming to assist in catheter feeding and ensuring the smooth progress of the construction process.

[0042] Specifically, the control unit 7 includes: a processing module 71, a collection module 72, and an execution module 73 that are communicatively connected; the collection module 72 is used to collect various data related to construction, such as the discharging speed of concrete, the operating status of each part of the equipment, etc. For example, these information can be obtained through various sensors. For example, a speed sensor monitors the discharging speed of concrete, and a displacement sensor monitors the position of the movable push plate 31, etc. The collection module 72 transmits the collected data to the processing module 71 in real time.

[0043] The processing module 71 is used to receive the data from the collection module 72, and analyze, process, and judge these data. For example, when the processing module 71 receives data that the discharging speed of concrete is lower than the preset speed value, the processing module 71 will analyze the possible reasons for the slow discharging speed, whether it is the blockage of the conduit or the inappropriate reciprocating frequency of the driving structure 32, etc. Then, the processing module 71 generates corresponding control instructions according to the analysis results and sends them to the execution module 73. Here, the preset speed value is set according to actual requirements.

[0044] The execution module 73 is used to receive the instructions issued by the processing module 71, and convert these instructions into actual operations, acting on the driving structure 32. For example, if the processing module 71 determines that it is necessary to increase the operating speed of the driving structure 32 to accelerate the discharging of concrete, the execution module 73 will send an instruction to the driving structure 32 to adjust its operating parameters, so that the driving structure 32 operates at a new speed, thereby achieving precise control of the construction platform and ensuring the efficiency and stability of the construction process.

[0045] Furthermore, as Figure 3 shown, protective plates 5 are provided at the edges of the support body 21 and the support chassis 41, and a lifting lug 45 is provided at one end of the guide rail 44 away from the support chassis 41.

[0046] It should be noted that protective plates 5 are provided at the edges of the support body 21 and the support chassis 41 to protect the safety of on-site personnel during construction. When the construction platform is operating, the support assembly 2 will reciprocate along the guide rail 44. There are relative moving parts between the support body 21 and the support chassis 41. When personnel operate and maintain the equipment, they may be pinched if they are not careful. The protective plate 5 is installed at the edges of these parts, which is equivalent to setting up a barrier between the dangerous area and personnel, blocking personnel from contacting the parts that may cause pinching. Here, the protective plate 5 is, for example, made of high-strength soft rubber or nylon material. The high strength endows it with certain structural strength and can withstand a certain degree of external force impact. During the movement of the equipment parts, it is not easily damaged even if it is collided, ensuring the continuous effectiveness of the protection function. The soft characteristic avoids the hard injury of the protective plate itself to personnel. Even if personnel accidentally contact the protective plate, the possibility of injury can be reduced. Rubber and nylon materials also have certain wear resistance. The construction environment is complex, and the protective plate 5 will also rub against other objects. The wear resistance ensures that the protective plate 5 will not be quickly damaged due to frequent friction during long-term use, extends the service life of the protective plate 5, and reduces the maintenance cost.

[0047] A lifting lug 45 is provided at one end of the guide rail 44 away from the support chassis 41, which is used to facilitate the hoisting work of the construction platform. During the installation, disassembly, and transfer of the construction platform, hoisting equipment needs to be used for handling. The lifting lug 45, as a specially designed hoisting connection component, provides a reliable connection point for the hook of the hoisting equipment. By connecting the hook with the lifting lug 45, it can be ensured that the construction platform is evenly and stably stressed during hoisting, avoiding safety accidents such as equipment shaking and falling caused by insecure connection or uneven stress, guaranteeing the safety and stability of the construction platform during hoisting, and improving the transfer efficiency of the construction equipment.

[0048] Furthermore, there is a hollow area on the support body 21 that communicates with the installation through hole 13, and the area of the hollow area of the support body 21 is smaller than the area of the cover plate structure 1.

[0049] It should be noted that the hollowed-out area is connected to the installation through-hole 13, facilitating the smooth insertion of the conduit into the pouring slot through the installation through-hole 13 and the hollowed-out area. The cover plate structure 1 is mainly used to accommodate the penetration of the conduit and fix the position of the conduit to a certain extent, and prevent foreign objects from falling into the pouring slot. A smaller hollowed-out area of the bracket main body 21 can provide a more stable installation foundation for the cover plate structure 1. When the conduit passes through the installation through-hole 13 of the cover plate structure 1 and is lowered into the pouring slot, part of the weight of the conduit will be transmitted to the bracket main body 21 through the cover plate structure 1. If the hollowed-out area of the bracket main body 21 is too large, it may cause the cover plate structure 1 to shake or become unstable during installation and use, affecting the positioning accuracy and stability of the conduit, and further affecting the pouring effect of the concrete. Moreover, a smaller hollowed-out area can also enable the bracket main body 21 to more effectively support the cover plate structure 1, ensure the stability of the conduit during pouring, and ensure that the concrete can be accurately poured to the designated position.

[0050] As Figure 5 shown, the present application also provides a method for using a diaphragm wall pouring construction platform, which is implemented based on the above-mentioned diaphragm wall pouring construction platform. The method includes the following steps: S100. Place the support chassis 41 on the foundation surface of the top of the pouring slot, open the movable cover plate 11 of the cover plate structure 1, pass the conduit through the installation through-hole 13, and make the snap ring engage with the edge of the installation through-hole 13 and close the movable cover plate 11.

[0051] S200. Perform the pouring operation and collect the concrete feeding information in real time. If it is recognized that the concrete in the concrete feeding information shows a stacking situation, then use the drive shaft of the drive structure 32 to drive the movable push plate 31 to reciprocate along the length direction of the support chassis 41. The movable push rod 22 slides in the stroke groove 33, and at the same time drives the bracket assembly 2 to reciprocate along the guide rail 44, so that the bracket assembly 2 collides with the support chassis 41 at a preset frequency to assist the conduit in discharging materials into the pouring slot.

[0052] S300. When the concrete in the concrete feeding information does not show a stacking situation, stop the operation of the drive structure 32, continue to perform the pouring operation, turn off the control unit 7 after the pouring is completed, open the movable cover plate 11, remove the conduit, and clean the concrete residue on the surface of the construction platform, and inspect and maintain the equipment.

[0053] It should be noted that placing the support chassis 41 on the foundation at the top surface of the casting slot hole is the basis for building the entire construction platform, ensuring the stability of the construction platform and avoiding problems such as tilting and sinking during construction, which may affect the construction quality and safety. Open the movable cover plate 11 of the cover plate structure 1 to create space for the installation of the conduit. The conduit is a key component for transporting concrete. Pass it through the installation through-hole 13 and make the snap ring engage with the edge of the installation through-hole 13, which can accurately position the conduit and ensure that it will not shake or shift during the casting process, guaranteeing that the concrete can be accurately cast into the slot hole. Close the movable cover plate 11, which can not only further fix the conduit but also prevent foreign objects from falling into the slot hole during construction, affecting the casting quality of the concrete.

[0054] It is possible to Collect the concrete discharging information, that is, image information, by using an image acquisition device such as a camera. Here, at the end of the conduit away from the casting slot hole, and a discharging funnel is installed at this end. The image acquisition device is installed on the discharging funnel to take images of the concrete discharging. If there is concrete accumulation in the discharging funnel, it indicates that there is a current accumulation situation; otherwise, there is no accumulation situation. When there is no accumulation situation, the casting operation is normally carried out. If there is an accumulation situation, the driving shaft of the driving structure 32 drives the movable push plate 31 to reciprocate along the length direction of the support chassis 41. The movement of the movable push plate 31 will cause the movable push rod 22 to slide in the stroke slot 33. Since the movable push rod 22 is connected to the support assembly 2, the sliding of the movable push rod 22 will drive the support assembly 2 to reciprocate along the guide rail 44, and then cause the support assembly 2 to collide with the support chassis 41 at a preset frequency. The vibration generated by this collision will be transmitted to the conduit, breaking the frictional force and cohesion structure of the concrete in the conduit, reducing the frictional force between the concrete and the inner wall of the conduit, improving the fluidity of the concrete, assisting the conduit to discharge materials into the casting slot hole, effectively preventing the conduit from being blocked, and improving the concrete casting speed and construction efficiency.

[0055] When there is no accumulation situation in the concrete of the concrete discharging information, stop the operation of the driving structure 22, continue the normal casting operation, and after the casting is completed, turn off the control unit 7 to stop the construction platform from working, avoiding energy waste and equipment wear caused by the equipment idling. Then open the movable cover plate 11 and remove the conduit. The removal process needs to be operated carefully to prevent the remaining concrete from dripping and causing pollution or harm to personnel. Clean the concrete residue on the surface of the construction platform to avoid the concrete drying on the surface of the equipment, affecting the appearance of the equipment and its next use, and at the same time preventing the concrete residue from corroding the equipment components. Check and maintain the equipment, check whether each component is damaged or worn, such as whether the guide rail 44 is deformed and whether the sliding of the movable push plate 31 is smooth, etc., discover and handle problems in a timely manner, make preparations for the next construction, and extend the service life of the equipment. Further, after the auxiliary conduit discharges materials into the pouring slot hole and before the pouring is completed, the following steps are further included: Real-time detection of the concrete discharging speed; If the discharging speed is lower than the preset speed value, stop the construction, and check whether the conduit is blocked, whether the reciprocating frequency of the driving structure 32 is appropriate, and monitor the collision situation between the monitoring bracket assembly 2 and the support chassis 41.

[0056] It should be noted that the concrete discharging speed is a key indicator for measuring whether the pouring construction is normal. Real-time detection of the discharging speed can timely detect the flow condition of the concrete in the conduit. If the discharging speed is too slow, it indicates that the concrete is blocked in the conduit, or there are problems with the mix ratio and fluidity of the concrete itself. Through continuous monitoring, the construction personnel can master the dynamic change of the discharging speed. Once an abnormality occurs, they can quickly take measures to avoid affecting the pouring progress and quality.

[0057] When it is detected that the concrete discharging speed is lower than the preset speed value, stopping the construction is to prevent the problem from deteriorating further. If the construction continues, it may cause the concrete to accumulate in the conduit, aggravating the blockage situation, and even require reprocessing the conduit, wasting a large amount of time and materials. Timely stopping the construction can provide time and conditions for subsequent inspections and problem-solving. Here, the preset speed value can be set according to actual needs.

[0058] Among them, catheter blockage is one of the common reasons for the reduction of the material discharging speed. When inspecting the catheter, construction workers need to check whether there are concrete lumps, foreign objects, etc. inside the catheter that hinder the flow of concrete. The blockage situation inside the catheter can be judged by observing whether there are abnormal vibrations and sounds outside the catheter, or by using special detection tools such as pressure sensors. If the catheter is found to be blocked, it is necessary to clean or replace the catheter in time to ensure the smooth discharging of concrete. The reciprocating frequency of the driving structure 32 directly affects the collision frequency between the support assembly 2 and the support chassis 41, and thus affects the auxiliary material discharging effect of the concrete in the catheter. If the reciprocating frequency of the driving structure 32 is too low, the generated vibration is not enough to break the frictional and cohesive structure of the concrete, resulting in difficult material discharging; if the frequency is too high, it may cause excessive impact on the equipment, affect the service life of the equipment, and even cause safety problems. Therefore, it is necessary to check whether the reciprocating frequency of the driving structure 32 conforms to the preset parameters and adjust it according to the actual situation. The collision between the support assembly 2 and the support chassis 41 is a key link for auxiliary concrete discharging. Monitor the collision situation, including the collision force, frequency, and position, etc. If the collision force is uneven, it may cause uneven stress on the catheter and affect the flow of concrete; if the collision frequency is unstable, it will also affect the auxiliary material discharging effect. By monitoring the collision situation, abnormalities during the operation of the equipment can be detected in time, such as whether the connection parts of the support assembly 2 are loose, whether the support chassis 41 is deformed, etc., so as to carry out maintenance and adjustment in time to ensure the normal operation of the construction platform.

[0059] When it is detected that the concrete discharging speed is maintained near the preset speed value, the current working state is maintained and the construction continues; when it is detected that the concrete discharging speed far exceeds the preset speed value, it indicates that there is a problem with the concrete mix ratio, such as an excessive water-cement ratio, resulting in the concrete being too soft and the fluidity increasing abnormally. In this case, it is necessary to check and re-detect the raw materials of the concrete to ensure that they meet the design requirements. If there is no problem with the concrete itself, the operating parameters of the driving structure can be adjusted through the control unit, such as reducing the movement speed of the driving structure 32, reducing the stroke, etc., so as to reduce the collision frequency and force between the support assembly 2 and the support chassis 41, thereby reducing the vibration effect on the concrete in the catheter, reducing the discharging speed, and avoiding uneven accumulation of concrete in the pouring slot hole due to too fast discharging speed, which affects the pouring quality.
