Description
Technical Field
[0001] This utility model belongs to the field of pier construction, specifically relating to a high-precision embedded prism device for pier construction. Background Technology
[0002] In the construction of piers for bridges, overpasses, and elevated roads, accurate measurement is crucial to ensuring the overall geometric shape and positional accuracy of the subsequent structure. Traditional field measurements often use total stations or laser scanners in conjunction with reflecting prisms (hereinafter referred to as "prisms") to collect coordinates. The prism accurately returns the reflected signals to the measuring instrument.
[0003] However, existing prisms are usually temporarily fixed to the outer surface of the formwork or steel pipe support using methods such as double-sided tape, nylon cable ties, and magnetic bases. These fixing methods are difficult to resist the vibration of pouring, formwork vibration, and lateral impacts during worker operation. The prism is prone to slight displacement, which leads to the deviation of the measurement point, and thus directly affects the measurement accuracy and geometric connection of subsequent construction, as well as the verticality of the pier.
[0004] Therefore, the existing prisms used for pier construction have insufficient measurement and positioning accuracy. Utility Model Content
[0005] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies in the existing technology by providing a high-precision embedded prism device for pier construction, which has good measurement and positioning accuracy.
[0006] According to an embodiment of this utility model, a high-precision embedded prism device for pier construction is provided, comprising: an installation groove and a prism module; the installation groove is fixedly installed on the pier template, the installation groove comprising: a groove opening, a rear end face opposite to the groove opening, and a first side wall and a second side wall arranged parallel to each other, both the first side wall and the second side wall being provided with guide grooves, the guide grooves extending in the front-back direction, the prism module being accommodated in the installation groove, the insertion end of the prism module abutting against the rear end face to achieve positioning of the prism in the front-back direction, the bottom surface of the installation groove being used for... The prism module is supported to achieve vertical positioning of the prism. Guide ribs are provided on both the left and right outer walls of the prism module. The two guide ribs are respectively matched with two guide grooves. The guide grooves are used to position the prism module in the left and right directions. An elastic clamping unit is provided in the mounting groove. The elastic clamping unit is installed on one of the first side wall and the second side wall. The elastic clamping unit is used to apply pressure to the side of the prism module, so that the prism module is tightly attached to the other side wall and the guide groove on that side wall.
[0007] The high-precision embedded prism device for pier construction in this embodiment of the invention achieves three-dimensional positioning of the prism module through the rear end face, bottom face, and left and right side walls of the mounting groove. It should be noted that the cooperation between the guide groove and the guide ribs not only further restricts the prism module's displacement in the left and right directions but also limits minor vibrations. Specifically, to facilitate the insertion of the prism module into the mounting groove, a gap is usually left between the prism module and the inner wall of the mounting groove. During pier construction, vibrations from pouring, formwork vibrations, and lateral impacts from worker operations can easily cause minor displacements and vibrations in the mounting groove, especially vertical vibrations. The guide ribs in this prism device effectively limit these vertical vibrations, thereby ensuring the positioning accuracy of the prism module. Furthermore, due to the gap between the prism module and the inner wall of the mounting groove, it is difficult to achieve precise positioning of the prism module in the left-right direction. In this device, an elastic clamping unit presses the prism module against another side wall and the guide groove on that side wall, enabling the prism module to be precisely installed and positioned. In summary, this high-precision embedded prism device for pier construction can effectively achieve good positioning accuracy.
[0008] Optionally, there are multiple elastic clamping units, each of which is installed on one of the first sidewall and the second sidewall. The sidewall on which the multiple elastic clamping units are installed is designated as the mounting sidewall. Each elastic clamping unit includes an elastic element and a clamping element. The clamping element is elastically connected to the mounting sidewall through the elastic element. The elastic element extends in the horizontal direction and can be compressed and contracted in the horizontal direction, thereby applying pressure to the side of the prism module.
[0009] Optionally, the mounting sidewall is provided with elastic element receiving grooves, the number of elastic element receiving grooves is the same as the number of elastic clamping units, and each elastic element receiving groove is equipped with an elastic clamping unit. The clamping element of each elastic clamping unit is elastically connected to the bottom of the elastic element receiving groove through an elastic element. When the prism module is inserted from the inlet of the mounting groove, the elastic element is compressed, thereby applying pressure to the side of the prism module.
[0010] Optionally, the elastic element is a compression spring, and the clamping element is a pin or a tapered stud.
[0011] Optionally, the cross-sectional shape of the guide groove is V-shaped or rectangular.
[0012] Optionally, the prism module includes a prism body and a housing; the shape of the housing matches the shape of the mounting groove, and a receiving groove is provided on one side of the housing. The shape of the receiving groove matches the shape of the prism body. The receiving groove is used to receive the prism body, and the prism body is bonded and fixed in the receiving groove.
[0013] Optionally, the prism body is a pyramidal prism.
[0014] Optionally, the housing is made of aluminum alloy, stainless steel, polyamide (PA), or polycarbonate (PC).
[0015] Optionally, the device further includes a locking structure, which includes a threaded base and a locking screw. The threaded base is fixedly installed on the top of the mounting groove, and the inner hole of the threaded base is provided with an internal thread. The locking screw passes through the inner hole of the threaded base and is threadedly engaged with the inner hole of the threaded base. The lower end of the locking screw is provided with a locking pressure ring, which is used to press the prism module downward.
[0016] Optionally, a sealing ring is provided between the outer wall of the prism module and the opening of the mounting groove; a drain outlet is provided at the bottom of the inner end face of the mounting groove; and a baffle is provided at the upper end of the opening of the mounting groove to block splashed mud and sand.

[0019] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of this utility model.
[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience and simplification of the description and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection," "setting," "installation," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0023] First, it should be noted that accurate measurement is crucial for ensuring the overall geometric shape and positional accuracy of the structure during the construction of piers in bridges, overpasses, and elevated roads. Traditional field measurements often use total stations or laser scanners in conjunction with reflecting prisms (hereinafter referred to as "prisms") to collect coordinates. Prisms can accurately return reflected signals to the measuring instrument, but existing prisms still have several shortcomings in field applications, mainly in the following aspects: 1. Poor prism positioning stability Traditionally, prisms are temporarily fixed to the outer surface of the formwork or steel pipe supports using methods such as double-sided tape, nylon cable ties, or magnetic bases. These fixing methods are difficult to withstand the vibrations of pouring, formwork vibrations, and lateral impacts during worker operations. The prism is prone to slight displacement, causing the measurement reference point to shift, which in turn directly affects the measurement accuracy and the geometric alignment of subsequent construction.
[0024] 2. Insufficient accuracy due to repeated disassembly and reassembly. During the removal, pouring, and finishing of the formwork, the prism needs to be disassembled and reinstalled multiple times to meet the needs of subsequent measurements. Existing processes rely heavily on manual visual positioning and temporary calibration, sometimes requiring multiple calibrations to ensure that the new installation position is close to the original position. However, the reset error after each disassembly and reassembly often exceeds the allowable tolerance, increasing measurement errors and the workload of secondary calibration, and reducing on-site operation efficiency.
[0025] 3. Installation efficiency urgently needs to be improved. Because the temporary fixing method of the prism lacks a standardized design, the installation requires repeated fine-tuning of the position, prism height, horizontal angle and pitch angle. This series of manual operations usually takes 1 to 2 minutes and depends on the experience of the surveyors. It is inefficient and prone to introducing systematic errors due to improper operation, which affects the construction progress.
[0026] 4. Poor adaptability to the on-site environment Pier construction sites are typically accompanied by large amounts of concrete pouring, vibration, and mud splashing. Traditional prism fixing methods lack effective protective designs and are prone to failure due to moisture-induced adhesive failure, mechanical clips jammed by mud or rust, leading to prism detachment or displacement. In severe cases, this can even cause measurement interruptions and work stoppages for rework.
[0027] 5. Lack of data traceability and tracking management The existing prism installations do not achieve standardized and modular design, and cannot form a corresponding relationship with the measurement system's backend database. Different prisms on the construction site often cannot quickly identify their corresponding template positions or historical calibration status, which brings difficulties to data management, quality traceability, and responsibility division. Example 1
[0028] Please see Figure 1 and Figure 2 This utility model discloses a high-precision embedded prism device for pier construction, comprising: an installation groove 1 and a prism module 2.
[0029] The mounting groove 1 is fixedly installed on the pier column template. The mounting groove 1 includes: a groove opening, a rear end face opposite to the groove opening, and a first side wall and a second side wall arranged in parallel on the left and right sides. The first side wall and the second side wall are each provided with a guide groove 11, which extends in the front-back direction. The prism module 2 is housed in the mounting groove 1, and the insertion end of the prism module 2 abuts against the rear end face to achieve positioning of the prism in the front-back direction. The bottom surface of the mounting groove 1 is used to support the prism module 2 to achieve positioning of the prism in the vertical direction. The left and right outer side walls of the prism module 2 are each provided with a guide rib 221, and the two guide ribs 221 are respectively matched with two guide grooves 11. The guide grooves 11 are used to position the prism module 2 in the left and right directions. The mounting groove 1 is provided with an elastic pressing unit 3, which is installed on one of the first side wall and the second side wall. The elastic pressing unit 3 is used to apply pressure to the side of the prism module 2, so that the prism module 2 is tightly attached to the other side wall and the guide groove 11 on that side wall.
[0030] The high-precision embedded prism device for pier construction in this embodiment achieves three-dimensional positioning of the prism module 2 through the rear end face, bottom face, and left and right side walls of the mounting groove 1. It should be noted that the cooperation between the guide groove 11 and the guide rib 221 not only further restricts the displacement of the prism module 2 in the left and right directions but also limits minor vibrations of the prism module 2. Specifically, to facilitate the insertion of the prism module 2 into the mounting groove 1, a gap is usually left between the prism module 2 and the inner wall of the mounting groove 1. During pier construction, vibrations from pouring, formwork vibrations, and lateral impacts from worker operations can easily cause minor displacements and vibrations in the mounting groove 1, especially vertical vibrations. The guide rib 221 in this prism device effectively limits these vertical vibrations, thereby ensuring the positioning accuracy of the prism module 2. Furthermore, since there is a gap between the prism module 2 and the inner wall of the mounting groove 1, it is difficult to achieve precise positioning of the prism module 2 in the left and right directions. In this device, the prism module 2 is pressed against another side wall and the guide groove 11 on the side wall by the elastic clamping unit 3, so that the prism module 2 can be accurately installed and positioned.
[0031] For example, such as Figure 3 As shown, the elastic clamping unit 3 is installed on the first side wall on the left side, pressing the prism module 2 against the second side wall on the right side and the guide groove 11 on the second side wall. Therefore, there is a gap between the left side of the prism module 2 and the first side wall.
[0032] In summary, the high-precision embedded prism device used in the construction of this pier column can effectively achieve good measurement and positioning accuracy.
[0033] Please see Figure 2In this embodiment, there are multiple elastic pressing units 3, and each of the multiple elastic pressing units 3 is installed on one of the first side wall and the second side wall. The side wall on which the multiple elastic pressing units 3 are installed is designated as the mounting side wall. The elastic pressing unit 3 includes an elastic element 31 and a pressing element 32. The pressing element 32 is elastically connected to the mounting side wall through the elastic element 31. The elastic element 31 extends in the horizontal direction and can be compressed and contracted in the horizontal direction, thereby applying pressure to the side of the prism module 2.
[0034] For example, multiple elastic clamping units 3 are all installed on the first side wall on the left side. The multiple elastic clamping units 3 apply pressure to the left side wall of the prism module 2, so that the prism module 2 is tightly attached to the second side wall. This enables precise positioning of the prism module 2 in the left and right horizontal directions.
[0035] Furthermore, such as Figure 4 and Figure 5 As shown, the mounting side wall is provided with elastic element receiving grooves 12. The number of elastic element receiving grooves 12 is the same as the number of elastic pressing units 3. Each elastic element receiving groove 12 is equipped with an elastic pressing unit 3. The pressing element 32 of each elastic pressing unit 3 is elastically connected to the bottom of the elastic element receiving groove 12 through an elastic element 31. When the prism module 2 is inserted from the inlet of the mounting groove 1, the elastic element 31 is pressed, thereby applying pressure to the side of the prism module 2.
[0036] Among them, the elastic element 31 is a compression spring, and the clamping element 32 is a pin or a tapered stud.
[0037] like Figure 5 As shown, Figure 5 The middle clamping member 32 is a pin, and the size of the elastic member receiving groove 12 is matched with the clamping member 32, so as to guide the clamping member 32 and avoid the clamping member 32 and the elastic member 31 from deviating from the trajectory.
[0038] like Figure 4 As shown, in this embodiment, the cross-sectional shape of the guide groove 11 is V-shaped or rectangular.
[0039] It should be noted that during the pier construction process, the vibration from pouring, the vibration of the formwork, and the lateral impact from workers' operations can easily cause slight displacement and shaking in the installation groove 1, especially vertical shaking. The V-shaped or rectangular guide groove 11 can effectively limit the vertical shaking of the prism.
[0040] As can be seen, this device, through the cooperation between the guide groove 11, the guide prism 221, and the elastic clamping unit 3, can significantly improve measurement accuracy. Utilizing standardized modules and pre-calibrated prism components, combined with precision-machined guide grooves and fine-tuning locking structures 4, the prism coordinate deviation can be controlled within ±0.05 mm, meeting the stringent millimeter-level measurement requirements of bridge pier construction and avoiding cumulative errors caused by prism micro-movements. Furthermore, it eliminates the need to re-calibrate parameters for each installation and avoids manual recalibration. The cooperation between the guide groove and the locking device makes the reset error after repeated disassembly and assembly negligible, saving significant pre-measurement work time and improving construction progress.
[0041] In this embodiment, the prism module 2 includes a prism body 21 and a housing 22. The shape of the housing 22 matches the shape of the mounting groove 1, and a receiving groove is provided on one side of the housing 22. The shape of the receiving groove matches the shape of the prism body 21. The receiving groove is used to receive the prism body 21, and the prism body 21 is bonded and fixed in the receiving groove.
[0042] Optionally, the prism body 21 is a pyramidal prism.
[0043] Specifically, the outer shell 22 is made of aluminum alloy, stainless steel, polyamide (PA), or polycarbonate (PC).
[0044] In other words, prism module 2 adopts an integrated design. The high-precision reflecting prism is housed within a CNC-machined metal (such as aluminum alloy or stainless steel) or high-strength engineering plastic (such as polyamide PA or polycarbonate PC) shell 22, and double-secured by mechanical clips and epoxy bonding. Therefore, the shell 22 of prism module 2 in this device is made of corrosion-resistant material, enhancing environmental adaptability, ensuring long-term stable operation of the prism, and making it suitable for various complex construction environments.
[0045] In this embodiment, the device further includes a locking structure 4. The locking structure 4 includes a threaded base 41 and a locking screw. The threaded base 41 is fixedly installed on the top of the mounting groove 1, and the inner hole of the threaded base 41 is provided with internal threads. The locking screw passes through the inner hole of the threaded base 41 and is threadedly engaged with the inner hole of the threaded base 41. The lower end of the locking screw is provided with a locking pressure ring, which is used to press the prism module 2 downward.
[0046] The locking structure 4 is used to press the prism module 2 into the bottom of the mounting groove 1, thereby achieving the final fixation of the prism module 2. Of course, if only the locking structure 4 is used and the guide groove 11 is omitted, the problem of inaccurate positioning may easily occur, such as the problem that one side of the prism module 2 is high and the other side is low.
[0047] In this embodiment, a sealing ring is provided between the outer wall of the prism module 2 and the opening of the mounting groove 1. A drain outlet is provided at the bottom of the inner end face of the mounting groove 1. A baffle 5 is provided at the upper end of the opening of the mounting groove 1, which is used to block splashed mud and sand.
[0048] It is evident that this device also solves the problem of poor adaptability of current prism devices to on-site environments. It should be noted that pier construction sites are typically accompanied by large amounts of concrete pouring, vibration, and mud splashing. Traditional prism fixing methods lack effective protective designs and are prone to failure due to adhesive dampness, mechanical clips jammed by mud, or rust, leading to prism detachment or displacement, and in severe cases, even measurement interruptions and work stoppages. This device, however, enhances environmental adaptability and durability by incorporating a sealing ring, drainage outlet, and baffle 5. The module shell 22 is made of corrosion-resistant material and features a replaceable sealing ring and mud-proof baffle 5, effectively isolating concrete slurry, mud, and water mist from intrusion, ensuring long-term stable operation of the prism and making it suitable for various complex construction environments.
[0049] Moreover, this device can reduce maintenance costs. Its modular design facilitates quick replacement of easily damaged parts (such as seals, springs, etc.) and can be completed on-site without disassembling the entire template, reducing downtime losses and lowering subsequent maintenance costs.
[0050] The assembly process of the high-precision embedded prism device used in the construction of this pier is as follows: First, align the insertion end of prism module 2 with the opening of mounting slot 1, and align the guide rib 221 on the side wall of prism module 2 with the guide groove 11. Insert the insertion end of prism module 2 into mounting slot 1. At this time, the guide rib 221 is also inserted into the guide groove 11. During installation, the guide groove 11 guides prism module 2, eliminating the need for additional height calibration. Next, push prism module 2 into mounting slot 1 until the insertion end of prism module 2 abuts against the rear end face. During insertion into mounting slot 1, the elastic clamping unit 3 continuously applies pressure to the side wall of prism module 2, ensuring it adheres tightly to the other side wall. Finally, after prism module 2 is in place, lock it in place using the locking device to complete the assembly. In summary, this device solves the problem of insufficient accuracy during repeated disassembly and reassembly, thereby improving installation efficiency.
[0051] This device can improve construction efficiency and safety. The modular plug-in method is simple and easy to use. The time for a single installation and disassembly operation is controlled within 30 seconds. Operators do not need to perform high-altitude or dangerous operations, reducing fatigue and safety hazards. Example 2
[0052] This embodiment is a further explanation and optimization of the high-precision embedded prism device for pier construction in Embodiment 1, aiming to provide more detailed technical details or demonstrate the application effect of the device under different conditions.
[0053] Please see Figure 1 and Figure 2 The high-precision embedded prism device for pier construction is an improvement solution proposed to address the problems of unstable prism positioning, poor resetting accuracy, low installation efficiency, poor environmental adaptability, and insufficient traceability management in existing pier construction. The key technical points are detailed below.
[0054] 1. Design of integrated prism module 2 This device adopts a modular packaging structure: the high-precision reflective prism is placed in a CNC precision-machined metal (such as aluminum alloy or stainless steel) or high-strength engineering plastic (such as polyamide PA or polycarbonate PC) shell 22, and is double-fixed by mechanical buckles and epoxy bonding.
[0055] By precisely controlling the dimensions during processing (the outer shell 22 corresponds perfectly to the pre-reserved groove of the template, and the overall tolerance is controlled within ±0.02 mm), it can be ensured that the module can be initially positioned without any fine-tuning.
[0056] In addition, this device also has excellent corrosion resistance and wear resistance. Specifically, the surface of the metal shell 22 is anodized or sandblasted (if the shell 22 of the prism module 2 is made of engineering plastic, UV-resistant and anti-aging modifiers are added) to improve its long-term outdoor service life.
[0057] 2. Standardized template mounting slot 1 structure First, the positioning groove is precision machined (the installation groove 1 at the designated position is pre-machined on the side wall or bottom plate of the pier column formwork, and the groove is lined with a hard alloy or high-strength steel sleeve) to resist the pouring pressure and vibration wear.
[0058] Secondly, a two-way guiding design is adopted. Specifically, the inner wall of the groove is designed with a V-shaped or rectangular groove, which corresponds to the guide ribs 221 on the side or bottom of the prism module 2, so that the module can automatically return to its position in two vertical directions, reducing the number of manual corrections.
[0059] Finally, by adopting a tight fit clearance (i.e., minimizing the gap while ensuring installation), the slot width and module width are left with an interference fit of 0.1 mm, which controls the lateral and longitudinal movement range of the module in the slot while guiding it.
[0060] 3. Fine-tuning adjustment mechanism An elastic clamping element is installed in the mounting groove 1. Specifically, a replaceable spring pin or tapered spring stud is installed on the side wall of the mounting groove 1. After the module is inserted, it achieves a micro-motion range of ±1 mm under the guidance of the groove and the preload of the spring.
[0061] A locking structure 4 is installed at the top of the mounting slot 1. The top of the prism module 2 is fitted with a tightening nut, which can be tightened with a torque wrench with one click. This can achieve rapid curing and also avoid damage to the slot due to overtightening.
[0062] A visual adjustment scale is set in prism module 2. Specifically, scale lines are engraved on the side of prism module 2, which are aligned with the baseline scale on mounting slot 1 to achieve quantitative fine-tuning and reduce human visual error.
[0063] 3. Protective sealing design The design incorporates replaceable sealing rings. EPDM or fluororubber sealing rings are embedded at the contact surfaces between the module and the tank, allowing for quick replacement as needed to prevent the ingress of mud and concrete slurry.
[0064] Add mud and sand baffles 5. The sides and front of the module are equipped with foldable baffles 5, which can block splashing mud and sand without affecting the optical reflective surface and facilitate cleaning.
[0065] A drainage channel is added to the bottom of the installation slot 1: a micro drainage ditch is designed at the bottom of the slot, which can automatically drain water or mud, avoiding liquid accumulation and corrosion or deformation of the sealing ring due to pressure.
[0066] 4. Quick plug-in / reset markings A unique module ID is assigned to prism module 2. Specifically, a QR code or laser number is engraved on the surface of each prism module 2, which corresponds one-to-one with the measurement system's backend database. The current module status and historical calibration data can be quickly identified on-site by scanning the code.
[0067] Data linkage can be achieved through module IDs. The measurement system software can read the module ID in real time, automatically recall the corresponding calibration parameters and the previous measurement reference point, and realize one-click calibration and error verification.
[0068] Positioning groove markings can also be added. Specifically, a "◆" or "T" shaped positioning recess is reserved on the mounting groove 1, with a corresponding protrusion on the bottom of the module. The correct positioning can be confirmed by "clicking" or "listening to the sound".
[0069] 5. Maintainability and scalability This device enables modular maintenance, meaning that the prism module 2 can be detached from the tank and disassembled separately for optical mirror cleaning or seal replacement, reducing the overall disassembly and maintenance cycle of the template. This device is equipped with a reserved expansion interface. Specifically, a sensor interface is reserved on the side wall of the module, which can integrate temperature and humidity sensors, tilt sensors, etc., for construction environment monitoring and real-time error compensation.
[0070] Moreover, this device facilitates standardized mass production. By unifying design standards, it enables batch processing and rapid assembly of the prism module 2 and the template groove, reducing production costs and improving on-site assembly consistency.
[0071] The following is a description of the manufacturing and use process of this device: During the module and positioning groove (guide groove) processing stage, according to the construction drawings, grooves are reserved in the pier column formwork and processed into guide grooves. The guide groove guides the module to automatically center in the horizontal and vertical directions through a V-shaped or rectangular groove structure, so as to complete the processing of prism module 2 and guide groove 11.
[0072] During the manufacturing process, a high-precision reflecting prism is installed into the corrosion-resistant module housing 22 and optical calibration is completed to finalize module pre-assembly and numbering. Then, a unique QR code is engraved or affixed to the module's exterior for rapid on-site identification and data retrieval.
[0073] During the on-site installation phase, the first step is QR code scanning for positioning. Construction personnel scan the module's QR code, and the measurement system automatically loads the corresponding calibration parameters. Next, insertion and positioning are performed by sliding the module into the guide groove, ensuring initial alignment through the groove's structure. Then, manual fine-tuning is conducted using the scale or handle on the module's side to slightly adjust the prism surface position, ensuring it is parallel to the template's reference surface. Finally, the module is secured and locked in place by tightening the top locking device, ensuring it is firmly seated in the groove without displacement.
[0074] During the measurement and verification phase, that is, immediately after installation, coordinate measurements are performed to verify whether the prism position meets the accuracy requirements.
[0075] When the project requires dismantling, simply loosen the locking device in reverse order, gently pull out the module, and clean the sealing components to easily complete the dismantling.
[0076] When a second installation (or repeated reset) is required, repeat the "insert - fine-tune - lock" steps. Relying on the guide groove and locking mechanism, automatic reset is achieved without additional calibration.
[0077] Depending on the site environment, routine maintenance and periodic inspection of the seals and protective baffles 5 are required, with replacements as needed. The module calibration cycle can be determined by the frequency of use; generally, it is recommended to perform an optical retest after every 20 insertions and removals. Specifically, optical retesting refers to in-situ accuracy verification to ensure the measurement and positioning accuracy of the prism.
[0078] The high-precision embedded prism design and fixing method of the present invention has the following significant advantages: 1. Significantly improve measurement accuracy: By using standardized modules and pre-calibrated prism components, combined with precision-machined guide grooves and fine-tuning locking structures, the prism coordinate deviation can be controlled within ±0.05 mm, meeting the stringent requirements for millimeter-level measurements in bridge pier construction and avoiding cumulative errors caused by prism micro-movements.
[0079] 2. Reduce on-site calibration and calibration workload: Calibration parameters are automatically retrieved by scanning QR codes, eliminating the need for manual recalibration; the combination of guide grooves and locking devices ensures that the reset error after repeated disassembly and assembly is negligible, saving a significant amount of pre-measurement work time and improving construction progress.
[0080] 3. Improve construction efficiency and safety: The modular plug-in method is simple and easy to implement, and the time for a single installation and disassembly operation is controlled within 30 seconds. Operators do not need to perform high-altitude or dangerous operations, reducing fatigue and safety hazards.
[0081] 4. Enhanced environmental adaptability and durability: The module housing 22 is made of corrosion-resistant material and features a replaceable sealing ring and mud-proof baffle 5 design, effectively isolating concrete slurry, mud and water mist from intrusion, ensuring long-term stable operation of the prism, and making it suitable for various complex construction environments.
