Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an intelligent measurement system and construction method for sealing concrete. Background Technology

[0002] With the rapid development of the construction industry, a large number of bridges spanning rivers and seas are being constructed. Bottom sealing concrete refers to the concrete pouring at the bottom of the foundation or base during construction, forming a thick concrete layer. As an important component of the foundation structure of underwater piers, the quality of bottom sealing concrete construction directly affects the overall stability and safety of the bridge.

[0003] Traditional methods for constructing sealing concrete typically involve installing formwork on a reinforcing steel frame to define the shape and thickness of the concrete pour. Precast concrete is then pumped or manually poured into the formwork layer by layer. This traditional method is relatively simple and often relies on the experience of the workers. However, it lacks real-time monitoring and control, making it difficult to accurately assess the quality and stability of the concrete and precisely control its level. Therefore, while focusing on construction quality, it is advisable to introduce an intelligent measurement system to improve both efficiency and quality. This invention addresses these shortcomings. Summary of the Invention

[0004] Based on the aforementioned technical problems, this invention proposes an intelligent measurement system and construction method for sealing concrete.

[0005] This invention proposes an intelligent measurement system for sealing concrete, comprising side wall templates for pouring underwater pier columns. The cross-sections of four side wall templates are in contact with each other to form a pouring cavity. A support cover plate is fixedly installed on the upper surface of the four side wall templates by fixing bolts. A jacking cylinder is hinged to one side surface of each side wall template. A concrete guide pipe is slidably engaged with a guide block installed on the inner wall of the sliding hole through a through-hole on the central surface of the support cover plate. A material feeding mechanism is provided inside the concrete guide pipe. A lifting mechanism is provided on the upper surface of the support cover plate. A horizontal moving mechanism is provided on the lower outer surface of the concrete guide pipe.

[0006] The feeding mechanism uniformly feeds the poured concrete and agitates the concrete within the pouring cavity.

[0007] The lifting mechanism vertically lifts and lowers the concrete guide pipe within the sliding hole of the support cover plate.

[0008] The horizontal moving mechanism keeps the horizontal plane of the concrete in the pouring cavity moving horizontally upward.

[0009] Preferably, the feeding mechanism includes a bent pipe that is fixedly connected to one side of the upper end of the concrete conduit. A feeding hopper is fixedly connected to the upper surface of the bent pipe. A conveying screw is rotatably connected to the inner top surface of the concrete conduit via a bearing. A reduction motor is fixedly connected to the upper surface of the concrete conduit. The output shaft of the reduction motor extends into the interior of the concrete conduit and is fixedly connected to the upper surface of the conveying screw via a coupling.

[0010] Through the above technical solution, in order to uniformly deliver the concrete into the pouring cavity and facilitate accurate measurement of the pouring level, a material hopper is set on one side of the concrete guide pipe. The poured concrete enters the upper end of the concrete guide pipe from the bend, and the conveying screw is rotated by the action of the reduction motor, thereby conveying the concrete spirally into the pouring cavity.

[0011] Preferably, the feeding mechanism further includes hinged joints fixedly installed in a ring array on the outer surface of the lower end of the conveying screw, the free end of the hinged joints being fixedly connected to a screw tube block, and the inner surface of the screw tube block being fixedly connected to rake teeth in a rectangular array.

[0012] With the above technical solution, when the pier is placed in the water, the riverbed surface will be uneven. Concrete discharged from the lower end of the fixed concrete guide pipe will accumulate at a certain position in the pouring cavity. In order to disperse the poured concrete and fill the pouring cavity, the concrete guide pipe is moved down to the uneven position at the bottom of the pouring cavity. Then, the screw block with hinged joint is opened in an umbrella shape. As the screw block rotates with the conveying screw, the rake teeth on its inner surface rotate to stir and disperse the concrete, thereby quickly leveling the horizontal surface of the pouring cavity. When the upper surface of the poured concrete tends to be horizontal, the opened screw block closes and forms a conveying component with the conveying screw. As the conveying screw moves upward, the concrete is discharged.

[0013] Preferably, the feeding mechanism further includes an installation cavity through which the lower surface of the conveying screw is opened. A telescopic cylinder is fixedly installed on the inner top wall of the installation cavity. A fixed plate is fixedly connected to the piston rod surface of the telescopic cylinder. Linkage rods are hinged in a ring array on the lower surface of the fixed plate. The lower outer surface of the linkage rod is hinged to the inner surface of the corresponding screw tube block.

[0014] The above technical solution controls the opening and closing of the screw tube block by using a telescopic cylinder in the mounting cavity to push the fixed plate up and down, thereby forcing the lower end of the linkage rod to open or close the hinged threaded tube block.

[0015] Preferably, the lifting mechanism includes symmetrically distributed adjusting screws, the lower outer surface of which is rotatably connected to the surface of the support cover plate via a bearing, and threaded sleeves are symmetrically distributed and fixedly connected to the outer surface of the concrete guide pipe, the inner surface of which is threadedly sleeved with the outer surface of the adjusting screws.

[0016] In order to control the uniform feeding of concrete into the duct and thus measure the flatness of the poured concrete surface, the above technical solution is used to control the uniform feeding of concrete into the duct and thus measure the flatness of the poured concrete surface. This is achieved by rotating two adjusting screws synchronously, which in turn causes the two threaded sleeves to drive the concrete duct to move linearly along the vertical direction of the adjusting screws, so that the lower surface of the concrete duct adapts to the height of the poured concrete.

[0017] Preferably, the lifting mechanism further includes a pulley assembly disposed inside the support cover plate, and the lower outer surface of the adjusting screw extends into the interior of the support cover plate and is connected to the pulley assembly for transmission.

[0018] In order to control the synchronous rotation of the two adjusting screws and thus achieve the height adjustment of the concrete guide pipe, the pulley assembly includes a pulley installed in a cavity inside the support cover plate, a transmission belt, and a drive motor installed on the surface of the support cover plate. The synchronous rotation of the two adjusting screws can be achieved through the transmission of the pulley assembly.

[0019] Preferably, the horizontal moving mechanism includes limiting grooves formed on the inner surfaces of the left and right side wall templates. The inner wall of the limiting groove is slidably engaged with a support panel with a round hole and a horizontal lower surface. The inner wall of the round hole of the support panel is movably sleeved with the outer surface of the concrete guide pipe. The lower surface of the support panel is provided with a swing frame for horizontal left and right movement.

[0020] Through the above technical solution, in order to control the surface of the poured concrete to remain horizontal and measure its flatness, the swing frame is controlled to move left and right on the lower surface of the support panel to smooth the contacted concrete surface. As the concrete is poured, the support panel drives the swing frame to move horizontally upward, thereby achieving control over the flatness of the concrete surface.

[0021] Preferably, the horizontal moving mechanism further includes U-shaped guide rods that are symmetrically distributed and fixedly connected to the lower surface of the support panel. The guide rods have grooved inner surfaces that are symmetrically distributed and slidably engaged with connecting rods that have grooves. The connecting rods have grooved inner surfaces that are slidably engaged with the outer surface of the swing frame. The lower outer surface of the concrete conduit is rotatably connected to a support pipe via a bearing. The lower outer surface of the support pipe is fixedly fitted with a cam panel. The outer surface of the cam panel is in slidable contact with the inner surface of the swing frame. The lower surfaces of the connecting rods, the swing frame, and the cam panel are all equipped with densely packed protrusions.

[0022] Through the above technical solution, in order to adjust the flatness of the upper surface of the poured concrete, the support pipe drives the cam panel to rotate. The arc-shaped convex surface of the cam panel can pull the swing frame to move left and right within the groove of the connecting rod. As the cam panel rotates circumferentially, it can pull the connecting rod to move back and forth within the groove of the guide rod, thereby smoothing the concrete in the pouring cavity. Furthermore, the connecting rod, swing frame, and the protrusions on the lower surface of the cam panel can sweep and smooth the concrete, thus keeping the gradually accumulating concrete surface flat. To measure the levelness of the poured concrete, sensor modules are distributed on the contact surfaces of the connecting rod, swing frame, and cam panel. The module includes photoelectric sensors, temperature and humidity sensors, and flow sensors. After the feeding mechanism moves the concrete at the bottom of the pouring cavity, the concrete touches the photoelectric sensors on the connecting rod, swing frame, and cam panel, which can detect that the concrete level is approaching horizontal. At the same time, the cam panel can be started to rotate and gradually raised, so that the measured concrete surface can be kept horizontal. The temperature and humidity sensors and flow sensors can be used to collect data during the bottom sealing concrete pouring process, such as temperature, humidity, and concrete flow. The external data processing module processes and analyzes the collected data to obtain the bottom sealing concrete level status and other data, which can be displayed through the external display module.

[0023] Preferably, the horizontal moving mechanism further includes an annular groove formed on the inner sidewall of the circular hole in the support panel; a linkage ring is fixedly sleeved on the outer surface of the middle part of the support tube; the outer surface of the linkage ring is rotatably sleeved with the inner wall of the annular groove; a drive gear ring is fixedly sleeved on the outer surface of the upper end of the support tube; a servo motor is fixedly mounted on the upper surface of the support panel via an L-shaped support beam; a linkage gear is fixedly connected to the outer surface of the output shaft of the servo motor via a coupling; the linkage gear meshes with the drive gear ring; and a contact switch is fixedly connected to the lower surface of the support cover plate; the lower surface of the contact switch slides in contact with the upper surface of the servo motor.

[0024] Through the above technical solution, in order to drive the cam panel to rotate and realize the swing of the swing frame and the connecting rod, thereby smoothing the concrete surface, the linkage gear is controlled by a servo motor to rotate, so that the meshing drive gear ring drives the cam panel on the outer surface of the support tube to rotate circumferentially to achieve the smoothing action. In order to control the support panel to rise with the concrete guide pipe, the support panel is connected to the support tube through the cooperation of the linkage ring and the annular groove. Then, the horizontal moving mechanism is gradually raised during concrete pouring. In order to limit the raising of the horizontal moving mechanism, a contact switch is set. When the upper surface of the servo motor housing contacts the contact switch, the lifting mechanism and the horizontal moving mechanism stop running. At this time, the support cover plate, together with the lifting mechanism and the horizontal moving mechanism, is removed, and the second layer of side wall template is installed on the upper surface of the first layer of side wall template. Then, the support cover plate is installed on the upper surface of the second layer of side wall template, and the operation of the first layer is repeated.

[0025] The present invention proposes a construction method for an intelligent measurement system for bottom sealing concrete, comprising the following steps:

[0026] S1. In order to build the pier in the water, the side wall templates are set up at the bottom of the river surrounded by the steel cofferdam by using the jacking cylinder. The four side wall templates are arranged to form a pouring cavity. The support cover plate is installed on the upper surface of the side wall templates by fixing bolts. At this time, the two adjusting screws are controlled to rotate by the pulley assembly. Under the connection of the threaded pipe sleeve, the lower end of the concrete guide pipe extends to the bottom of the pouring cavity.

[0027] S2. Concrete is poured into the hopper and enters the upper end of the concrete guide pipe through the bend. The conveying screw is rotated by the action of the reduction motor, and the concrete is then spirally conveyed to the inside of the pouring cavity. The bottom of the pouring cavity is uneven. In order to disperse the poured concrete and make the surface of the concrete more level, at the same time as the concrete is poured, the fixed plate is pushed downward by the telescopic cylinder installed in the cavity. This forces the lower end of the linkage rod to drive the hinged threaded pipe block to open in an umbrella shape. As the screw pipe block rotates with the conveying screw, the rake teeth on its inner surface can rotate to stir and disperse the concrete.

[0028] S3. As the filling concrete gradually begins to touch the photoelectric sensors on the connecting rod, swing frame, and cam panel, it can be detected that the concrete level is approaching horizontal. At the same time, the temperature and humidity sensor and the flow sensor measure the temperature, humidity, and flow rate of the concrete. Then, the external data processing module processes and analyzes the collected data to obtain the level status of the sealing concrete and other data, which can be displayed through the external display module.

[0029] S4. When the concrete touches the sensor module, the piston rod of the telescopic cylinder drives the threaded pipe block to close and reset, and then connects with the conveying screw to convey the concrete.

[0030] S5. In order to maintain the level of the measured concrete surface, the linkage gear is rotated by the servo motor during the continued pouring of concrete. This causes the meshing drive gear ring to drive the cam panel on the outer surface of the support tube to rotate circumferentially. At the same time, the linkage ring on the outer surface of the support tube rotates on the inner wall of the annular groove. As the cam panel rotates circumferentially, the arc convex surface of the cam panel can pull the swing frame to move left and right in the groove of the connecting rod. The connecting rod moves back and forth in the groove of the guide rod. In this way, the connecting rod, the swing frame, and the protrusion on the lower surface of the cam panel can sweep the concrete. At the same time, the state of the poured concrete can be monitored in real time, so that the flatness of the gradually accumulated concrete surface can be kept level.

[0031] S6. As the concrete is poured, the two adjusting screws are controlled to rotate through the pulley assembly. Under the connection of the threaded pipe sleeve, the concrete guide tube is gradually raised until the upper surface of the servo motor housing contacts the contact switch. Then the lifting mechanism and the horizontal moving mechanism stop running. At this time, the support cover plate is removed along with the lifting mechanism and the horizontal moving mechanism. The second layer of side wall template is installed on the upper surface of the first layer side wall template. Then the support cover plate is installed on the upper surface of the second layer side wall template, and the operation of the first layer is repeated.

[0032] The beneficial effects of this invention are as follows:

[0033] 1. By setting up a feeding mechanism, the concrete in the pouring cavity can be agitated to fill the uneven bottom of the river. During the adjustment process, the conveying screw is controlled by the action of the reduction motor, which then conveys the concrete into the pouring cavity. The telescopic cylinder installed in the cavity pushes the fixed plate downward, which in turn forces the lower end of the linkage rod to drive the hinged threaded tube block to open in an umbrella shape. As the screw tube block rotates with the conveying screw, the rake teeth on its inner surface can rotate to agitate and disperse the concrete, which makes it easy to quickly monitor the level of the concrete.

[0034] 2. By setting up a lifting mechanism, the concrete guide pipe can be gradually lifted in the pouring cavity. During the adjustment process, the two adjusting screws are controlled to rotate through the pulley assembly. With the connection of the threaded pipe sleeve, the concrete guide pipe is gradually lifted until the upper surface of the servo motor housing contacts the contact switch. Then the lifting mechanism and the horizontal movement mechanism stop running, which makes it easy to monitor the state of the concrete in real time and to level its surface.

[0035] 3. By setting up a horizontal moving mechanism, the surface of the poured concrete can be swept and smoothed in real time, thus maintaining its flatness. During the adjustment process, the linkage gear is rotated by the servo motor, which causes the meshing drive gear ring to drive the cam panel on the outer surface of the support tube to rotate circumferentially. At the same time, the linkage ring on the outer surface of the support tube rotates on the inner wall of the annular groove. As the cam panel rotates circumferentially, the arc convex surface of the cam panel can pull the swing frame to move left and right in the groove of the connecting rod. The connecting rod moves back and forth in the groove of the guide rod. In this way, the connecting rod, the swing frame, and the protrusion on the lower surface of the cam panel can sweep and smooth the concrete. At the same time, the state of the poured concrete can be monitored in real time, thus keeping the flatness of the gradually accumulating concrete surface level. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] Reference Figures 1-10 A smart measurement system for sealing concrete includes side wall templates 1 for pouring underwater pier columns. The cross-sections of four side wall templates 1 are in contact with each other to form a pouring cavity. Supporting cover plates 2 are fixedly installed on the upper surfaces of the four side wall templates 1 by fixing bolts. A jacking cylinder 9 is hinged to one side surface of the side wall templates 1. A concrete guide pipe 3 is slidably engaged with a guide block installed on the inner wall of the sliding hole through a through sliding hole on the surface of the supporting cover plate 2. A material feeding mechanism 4 is provided inside the concrete guide pipe 3. A lifting mechanism 6 is provided on the upper surface of the supporting cover plate 2. A horizontal moving mechanism 7 is provided on the lower outer surface of the concrete guide pipe 3.

[0049] Among them, the feeding mechanism 4 evenly feeds the poured concrete and agitates the concrete in the pouring cavity.

[0050] To ensure uniform delivery of the poured concrete into the pouring cavity and facilitate accurate measurement of the pouring level, the feeding mechanism 4 includes a bent pipe 41 fixedly connected to one side of the upper end of the concrete conduit 3. A feeding hopper 42 is fixedly connected to the upper surface of the bent pipe 41. A conveying screw 43 is rotatably connected to the inner top surface of the concrete conduit 3 via a bearing. A geared motor 44 is fixedly connected to the upper surface of the concrete conduit 3. The output shaft of the geared motor 44 extends into the interior of the concrete conduit 3 and is fixedly connected to the upper surface of the conveying screw 43 via a coupling. The poured concrete enters the upper end of the concrete conduit 3 through the bent pipe 41. The action of the geared motor 44 controls the rotation of the conveying screw 43, thereby spirally conveying the concrete into the pouring cavity.

[0051] When the pier is placed in the water, the riverbed surface may be uneven. Concrete discharged from the lower end of the fixed concrete guide pipe 3 may accumulate at a certain location in the pouring cavity. To disperse the poured concrete and ensure it fills the pouring cavity, the feeding mechanism 4 also includes hinged joints 45 arranged in a ring array and fixedly installed on the outer surface of the lower end of the conveying screw 43. The free end of the hinged joint 45 is fixedly connected to a screw tube block 46, and the inner surface of the screw tube block 46 is fixedly connected with rake teeth 47 arranged in a rectangular array. The concrete guide pipe 3 moves down to the uneven bottom of the pouring cavity, and then the screw block 46, which is hinged by the hinged joint 45, opens in an umbrella shape. As the screw block 46 rotates with the conveying screw 43, the rake teeth 47 on its inner surface rotate to stir and disperse the concrete, thereby quickly leveling the horizontal surface of the pouring cavity. When the upper surface of the poured concrete tends to be horizontal, the opened screw block 46 closes and forms a conveying component with the conveying screw 43. As the conveying screw 43 moves upward, the concrete is discharged.

[0052] In order to control the opening and closing of the screw tube block 46, the feeding mechanism 4 also includes an installation cavity 48 through which the lower surface of the conveying screw 43 is opened. A telescopic cylinder 49 is fixedly installed on the inner top wall of the installation cavity 48. A fixed plate 50 is fixedly connected to the piston rod surface of the telescopic cylinder 49. The lower surface of the fixed plate 50 is arranged in a ring array with hinged linkage rods 51. The lower outer surface of the linkage rod 51 is hinged to the inner surface of the corresponding screw tube block 46. The telescopic cylinder 49 in the installation cavity 48 pushes the fixed plate 50 to move up and down, thereby forcing the lower end of the linkage rod 51 to drive the hinged screw tube block to open or close.

[0053] By setting up the feeding mechanism 4, the concrete in the pouring cavity can be agitated to fill the uneven bottom of the river. During the adjustment process, the conveying screw 43 is rotated by the action of the reduction motor 44, which then conveys the concrete to the inside of the pouring cavity. The telescopic cylinder 49 installed in the cavity 48 pushes the fixed plate 50 to move downward, which in turn forces the lower end of the linkage rod 51 to drive the hinged threaded tube block to open in an umbrella shape. As the screw tube block 46 rotates with the conveying screw 43, the rake teeth 47 on its inner surface can rotate to agitate and disperse the concrete, which makes it easy to quickly monitor the level of the concrete.

[0054] Among them, the lifting mechanism 6 vertically lifts and lowers the concrete guide tube 3 on the inner wall of the sliding hole of the supporting cover plate 2.

[0055] To control the uniform feeding of concrete duct 3 and thus measure the flatness of the poured concrete surface, the lifting mechanism 6 includes symmetrically distributed adjusting screws 61. The lower outer surface of the adjusting screws 61 is rotatably connected to the surface of the support cover plate 2 via bearings. Threaded sleeves 62 are symmetrically distributed and fixedly connected to the outer surface of the concrete duct 3. The inner surface of the threaded sleeves 62 is threadedly engaged with the outer surface of the adjusting screws 61. By rotating the two adjusting screws 61 synchronously, the two threaded sleeves 62 can drive the concrete duct 3 to move linearly along the vertical direction of the adjusting screws 61, so that the lower surface of the concrete duct 3 adapts to the height of the poured concrete.

[0056] In order to control the synchronous rotation of the two adjusting screws 61 and thus realize the height adjustment of the concrete guide pipe 3, the lifting mechanism 6 also includes a pulley assembly 63 set inside the support cover plate 2. The lower outer surface of the adjusting screw 61 extends into the interior of the support cover plate 2 and is connected to the pulley assembly 63 for transmission. The pulley assembly 63 includes a pulley installed in a cavity opened inside the support cover plate 2, a transmission belt, and a drive motor installed on the surface of the support cover plate 2. The synchronous rotation of the two adjusting screws 61 can be realized through the transmission of the pulley assembly 63.

[0057] By setting up the lifting mechanism 6, the concrete guide pipe 3 can be gradually lifted in the pouring cavity. During the adjustment process, the pulley assembly 63 controls the rotation of the two adjusting screws 61, and the concrete guide pipe 3 is gradually lifted under the connection of the threaded sleeve 62 until the upper surface of the servo motor 81 housing contacts the contact switch 82. Then the lifting mechanism 6 and the horizontal moving mechanism 7 stop running, which makes it easy to monitor the state of the concrete in real time and to level its surface.

[0058] The horizontal moving mechanism 7 keeps the horizontal plane of the concrete in the pouring cavity rising horizontally.

[0059] To control the levelness of the poured concrete surface and measure its flatness, the horizontal movement mechanism 7 includes limiting grooves 71 on the inner surfaces of the left and right side wall templates 1. The inner wall of the limiting grooves 71 is slidably engaged with a support panel 72 with a round hole and a horizontal lower surface. The inner wall of the round hole of the support panel 72 is movably sleeved with the outer surface of the concrete guide tube 3. The lower surface of the support panel 72 is provided with a swing frame 73 that moves horizontally left and right. By controlling the swing frame 73 to move left and right on the lower surface of the support panel 72, the contacted concrete surface is smoothed. As the concrete is poured, the support panel 72 drives the swing frame 73 to move horizontally upward, thereby achieving control over the flatness of the concrete surface.

[0060] To adjust the flatness of the poured concrete surface, the horizontal moving mechanism 7 also includes U-shaped guide rods 74 symmetrically distributed and fixedly connected to the lower surface of the support panel 72. The guide rods 74 have grooved inner surfaces that are symmetrically slidably engaged with grooved connecting rods 75. The grooved inner surfaces of the connecting rods 75 are slidably engaged with the outer surface of the swing frame 73. The lower outer surface of the concrete guide tube 3 is rotatably connected to a support tube 76 via a bearing. A cam panel 77 is fixedly sleeved on the lower outer surface of the support tube 76. The outer surface of the wheel panel 77 slides in contact with the inner surface of the swing frame 73. Dense protrusions 78 are installed on the lower surfaces of the connecting rod 75, the swing frame 73, and the cam panel 77. The control support tube 76 drives the cam panel 77 to rotate. The arc-shaped convex surface of the cam panel 77 can pull the swing frame 73 to move left and right within the groove of the connecting rod 75. As the cam panel 77 rotates circumferentially, it can pull the connecting rod 75 to move back and forth within the groove of the guide rod 74, thereby smoothing the concrete in the pouring cavity. Furthermore, the connecting rod 75... The protrusions 78 on the lower surface of the swing frame 73 and cam panel 77 can sweep the concrete, thus keeping the surface of the gradually accumulating concrete level. In order to measure the level of the poured concrete, sensor modules are distributed on the contact surfaces of the connecting rod 75, swing frame 73, and cam panel 77. The sensor modules include photoelectric sensors, temperature and humidity sensors, and flow sensors. After the feeding mechanism 4 moves the concrete at the bottom of the pouring cavity, the concrete touches the photoelectric sensors of the connecting rod 75, swing frame 73, and cam panel 77, and the level of the concrete is measured to be approaching level. At the same time, the cam panel 77 can be started to rotate and gradually raised, so that the measured concrete surface can be kept level. The temperature and humidity sensors and flow sensors can be used to collect data during the pouring process of the sealing concrete, such as temperature, humidity, and concrete flow. The external data processing module processes and analyzes the collected data to obtain the level of the sealing concrete and other data, which can be displayed through the external display module.

[0061] To drive the cam panel 77 to rotate, thereby causing the swing frame 73 and connecting rod 75 to swing and smooth the concrete surface, and to control the support panel 72 to rise with the concrete guide pipe 3, the horizontal moving mechanism 7 also includes an annular groove 79 formed on the inner wall of the circular hole in the support panel 72. A linkage ring is fixedly sleeved on the outer surface of the middle part of the support pipe 76, and the outer surface of the linkage ring is rotatably sleeved with the inner wall of the annular groove 79. A drive gear ring 80 is fixedly sleeved on the outer surface of the upper end of the support pipe 76. A servo motor 81 is fixedly mounted on the upper surface of the support panel 72 through an L-shaped support beam. A linkage gear 83 is fixedly connected to the outer surface of the output shaft of the servo motor 81 through a coupling. The linkage gear 83 meshes with the drive gear ring 80. The servo motor 81 controls the rotation of the linkage gear 83, thereby causing the meshing drive gear ring 80 to drive the support panel 72. The cam panel 77 on the outer surface of the tube 76 rotates circumferentially to achieve a smoothing action. The support panel 72 is connected to the support tube 76 through the cooperation of the linkage ring and the annular groove 79. As the concrete is poured, the horizontal moving mechanism 7 is gradually lifted. In order to limit the lifting of the horizontal moving mechanism 7, a contact switch 82 is fixedly connected to the lower surface of the support cover plate 2. The lower surface of the contact switch 82 slides in contact with the upper surface of the servo motor 81. When the upper surface of the housing of the servo motor 81 contacts the contact switch 82, the lifting mechanism 6 and the horizontal moving mechanism 7 stop running. At this time, the support cover plate 2, together with the lifting mechanism 6 and the horizontal moving mechanism 7, is pulled out, and the second layer of the side wall template 1 is installed on the upper surface of the first layer of the side wall template 1. Then, the support cover plate 2 is installed on the upper surface of the second layer of the side wall template 1, and the operation of the first layer is repeated.

[0062] Reference Figures 1-3 A construction method for an intelligent measurement system for bottom sealing concrete includes the following steps:

[0063] S1. In order to build the pier in the water, the side wall template 1 is set up at the bottom of the river surrounded by the steel cofferdam by the jacking cylinder 9, so that the four side wall templates 1 surround to form a pouring cavity, and the support cover plate 2 is installed on the upper surface of the side wall template 1 by fixing bolts. At this time, the two adjusting screws 61 are controlled to rotate by the pulley assembly 63, and the lower end of the concrete guide pipe 3 is extended to the bottom of the pouring cavity under the connection of the threaded pipe sleeve 62.

[0064] S2. Concrete is poured into the hopper 42 and enters the upper end of the concrete guide pipe 3 through the bend 41. The conveying screw 43 is rotated by the action of the reduction motor 44, and the concrete is then spirally conveyed to the inside of the pouring cavity. The bottom of the pouring cavity is uneven. In order to disperse the poured concrete and make the surface of the concrete more level, at the same time as the concrete is poured, the fixed plate 50 is pushed downward by the telescopic cylinder 49 in the cavity 48. This forces the lower end of the linkage rod 51 to drive the hinged threaded pipe block to open in an umbrella shape. As the screw pipe block 46 rotates with the conveying screw 43, the rake teeth 47 on its inner surface can rotate to stir and disperse the concrete.

[0065] S3. As the filling concrete gradually begins to touch the photoelectric sensors of the connecting rod 75, swing frame 73, and cam panel 77, it can be detected that the concrete level line tends to be horizontal. At the same time, the temperature and humidity sensor and the flow sensor measure the temperature, humidity and flow rate of the concrete. Then, the external data processing module processes and analyzes the collected data to obtain the level status of the sealing concrete and other data, which can be displayed through the external display module.

[0066] S4. When the concrete touches the sensor module, the piston rod of the telescopic cylinder 49 drives the threaded pipe block to close and reset, and connects with the conveying screw 43 to convey the concrete.

[0067] S5. In order to maintain the level of the measured concrete surface, the servo motor 81 controls the linkage gear 83 to rotate while the concrete is being poured. This causes the meshing drive gear ring 80 to drive the cam panel 77 on the outer surface of the support tube 76 to rotate circumferentially. At the same time, the linkage ring on the outer surface of the support tube 76 rotates on the inner wall of the annular groove 79. As the cam panel 77 rotates circumferentially, the arc convex surface of the cam panel 77 can pull the swing frame 73 to move left and right in the groove of the connecting rod 75. The connecting rod 75 moves back and forth in the groove of the guide rod 74. Thus, the connecting rod 75, the swing frame 73, and the protrusion 78 on the lower surface of the cam panel 77 can sweep the concrete. At the same time, the state of the poured concrete can be monitored in real time, so that the flatness of the gradually accumulating concrete surface can be kept level.

[0068] S6. As the concrete is poured, the two adjusting screws 61 are rotated by the pulley assembly 63. Under the connection of the threaded sleeve 62, the concrete guide tube 3 is gradually raised until the upper surface of the servo motor 81 housing contacts the contact switch 82. Then the lifting mechanism 6 and the horizontal moving mechanism 7 stop running. At this time, the support cover plate 2 is removed together with the lifting mechanism 6 and the horizontal moving mechanism 7. The second layer side wall template 1 is installed on the upper surface of the first layer side wall template 1. Then the support cover plate 2 is installed on the upper surface of the second layer side wall template 1, and the operation of the first layer is repeated.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

7. A construction method based on the intelligent measurement system for bottom sealing concrete as described in claim 6, comprising the following steps: S1. In order to build the pier in the water, a side wall template (1) is set up at the bottom of the river surrounded by the steel cofferdam by using a jacking cylinder (9), so that the four side wall templates (1) surround to form a pouring cavity, and a support cover plate (2) is installed on the upper surface of the side wall template (1) by fixing bolts. At this time, the two adjusting screws (61) are controlled to rotate by the pulley assembly (63), and the lower end of the concrete guide pipe (3) is extended to the bottom of the pouring cavity under the connection of the threaded pipe sleeve (62). S2. Pour concrete into the hopper (42) and enter the upper end of the concrete guide pipe (3) through the bend (41). Control the conveying screw (43) to rotate by the action of the deceleration motor (44), and then convey the concrete to the inside of the pouring cavity. The bottom of the pouring cavity is uneven. In order to disperse the poured concrete and make the surface of the concrete tend to be horizontal, at the same time as the material is poured, the fixed plate (50) is pushed down by the telescopic cylinder (49) in the installation cavity (48), which forces the lower end of the linkage rod (51) to drive the hinged threaded pipe block to open in an umbrella shape. As the screw pipe block (46) rotates with the conveying screw (43), the rake teeth (47) on its inner surface can rotate to stir and disperse the concrete. S3. As the filling concrete gradually begins to touch the photoelectric sensors of the connecting rod (75), swing frame (73), and cam panel (77), it can be measured that the concrete level line tends to be horizontal. At the same time, the temperature and humidity sensor and the flow sensor measure the temperature, humidity and flow of the concrete. Then, the external data processing module processes and analyzes the collected data to obtain the horizontal state of the sealing concrete and other data, which can be displayed through the external display module. S4. When the concrete touches the sensor module, the piston rod of the telescopic cylinder (49) drives the threaded pipe block to close and reset, and connects with the conveying screw (43) to convey the concrete. S5. In order to maintain the level of the measured concrete surface, when the concrete continues to be poured, the linkage gear (83) is controlled to rotate by the servo motor (81), so that the meshing drive gear ring (80) drives the cam panel (77) on the outer surface of the support tube (76) to rotate circumferentially. At the same time, the linkage ring on the outer surface of the support tube (76) rotates on the inner wall of the annular groove (79). As the cam panel (77) rotates circumferentially, the arc convex surface of the cam panel (77) can pull the swing frame (73) to move left and right in the groove of the connecting rod (75). The connecting rod (75) moves back and forth in the groove of the guide rod (74). Then the connecting rod (75), the swing frame (73), and the protrusion (78) on the lower surface of the cam panel (77) can sweep the concrete. At the same time, the state of the poured concrete can be monitored in real time, so that the surface flatness of the gradually accumulated concrete can be kept level. S6. As the concrete is poured, the two adjusting screws (61) are rotated by the pulley assembly (63). The concrete guide pipe (3) is gradually lifted under the connection of the threaded sleeve (62) until the upper surface of the servo motor (81) housing contacts the contact switch (82). Then the lifting mechanism (6) and the horizontal moving mechanism (7) stop running. At this time, the support cover plate (2) is removed together with the lifting mechanism (6) and the horizontal moving mechanism (7). The second layer side wall template (1) is installed on the upper surface of the first layer side wall template (1). Then the support cover plate (2) is installed on the upper surface of the second layer side wall template (1), and the operation of the first layer is repeated.
