Description

Technical Field

[0001] This application relates to the technical field of well construction equipment, and in particular to an auxiliary device for the construction of municipal utility wells and its construction method. Background Technology

[0002] Currently, municipal utility manholes are core infrastructure for urban water supply and drainage and pipeline network supporting projects. They are widely used in construction scenarios such as roads, residential areas, and municipal pipeline networks. The quality of their masonry construction directly determines the stability of pipeline operation, seepage prevention performance, and road traffic safety. At present, the on-site masonry construction of municipal utility manholes, inspection wells, and supporting retaining walls still generally adopts the traditional construction method of manual layout based on experience and visual control of the outline, supplemented by simple temporary supports and string line calibration. The overall construction process is rough and lacks standardization.

[0003] In actual masonry work, existing construction methods have many inherent technical defects. The positioning of bricks and blocks lacks precise structural constraints, relying entirely on the experience of construction workers to control alignment and verticality. This easily leads to problems such as brick offset, tilting, and misalignment during construction, resulting in common quality defects such as deviations in the outline of manholes and retaining walls, excessive wall verticality, and uneven mortar joint thickness. This significantly reduces the overall integrity and compressive and shear strength of the masonry structure, and can later cause problems such as manhole cracking, wall deformation, and joint leakage. This not only affects the drainage efficiency of the pipe network but may also cause secondary problems such as road subsidence, failing to meet the standardized construction and acceptance specifications for municipal engineering. Summary of the Invention

[0004] This application provides a construction auxiliary device and construction method for municipal utility pipe wells, which can achieve precise positioning throughout the process, greatly improve the construction quality and service life of municipal pipe well projects, increase masonry construction efficiency, and reduce the probability of rework.

[0005] The technical solution of the auxiliary device for construction of municipal utility pipe wells provided in this application is as follows: A municipal utility manhole construction auxiliary device includes multiple columns and a sunshade fixedly mounted on the top of the columns. A lateral sliding component is mounted on the columns, and a longitudinal sliding component is mounted on the lateral sliding component. The longitudinal sliding assembly is equipped with a first limiting plate and a second limiting plate. The transverse sliding assembly is used to drive the first limiting plate and the second limiting plate to slide in the horizontal direction, and the longitudinal sliding assembly is used to drive the first limiting plate and the second limiting plate to rise and fall in the vertical direction. Multiple sets of first and second limiting plates together enclose a masonry construction area. The first and second limiting plates are used to fit the outer wall of the masonry block, to limit the outline and calibrate the verticality of the masonry block, and to adjust and adapt layer by layer as the masonry height increases, thus completing the masonry guidance and limiting.

[0006] Preferably, the lateral sliding assembly includes a lateral slide rail mounted between the two side columns, and a lateral slide block is slidably mounted on the lateral slide rail; the longitudinal sliding assembly includes a vertical slide rail mounted on the lateral slide block, and a longitudinal slide block is slidably mounted on the vertical slide rail; the first limiting plate and the second limiting plate are mounted on the longitudinal slide block.

[0007] Preferably, a load-bearing frame is detachably mounted between the corresponding transverse slide rails, and the load-bearing frame is slidably mounted on the transverse slide rail; multiple sets of locking members are provided on the longitudinal slide block, and each set of locking members is arranged sequentially at intervals along the sliding direction of the longitudinal slide block on the vertical slide rail; a linkage fixing component is mounted on the load-bearing frame, and when the locking member is inserted into the linkage fixing component, the linkage fixing component locks the transverse slide block on the transverse slide rail, and at the same time locks the longitudinal slide block on the vertical slide rail.

[0008] Preferably, the linkage fixing assembly includes a fixing seat that slides longitudinally on the load-bearing frame, and the fixing seat is provided with a pin for inserting and fixing into a pin hole in the transverse slide rail; the fixing seat is also provided with a trigger plate located on the lifting path of the locking member, and when the locking member is mounted on the trigger plate, the longitudinal slide seat presses and fixes the pin in the corresponding pin hole; the linkage fixing assembly also includes a return spring provided on the load-bearing frame, and the return spring extends and retracts along the sliding direction of the fixing seat; the return spring is used to push the fixing seat to maintain an upward lifting state until the pin and the pin hole are separated.

[0009] Preferably, the second limiting plates are located on both sides of the first limiting plate, and the two second limiting plates slide along the length direction of the first limiting plate; a bidirectional screw is mounted on the first limiting plate, and the second limiting plates are symmetrically arranged at both ends of the bidirectional screw, and the bidirectional screw is used to synchronously drive the two second limiting plates to move towards each other or away from each other.

[0010] Preferably, a material transport trolley is slidably mounted on the load-bearing frame, and a connecting rod is detachably installed on the material transport trolley. The material transport trolley is equipped with a material transport basket via the connecting rod.

[0011] Preferably, the material basket is provided with a hanging member, and the hanging member has through holes, which are arranged at intervals along the length of the hanging member.

[0012] Preferably, a construction platform is detachably mounted on the suspension component via a hanging hole, and the construction platform is suspended and fixed on the suspension component.

[0013] This application also provides a construction method for a municipal utility pipe well construction auxiliary device, using the aforementioned municipal utility pipe well construction auxiliary device. Technical solution: S1. Adjust the positions of the first limiting plate and the second limiting plate to form a masonry construction area by enclosing the area, so that the first limiting plate and the second limiting plate are in contact with the outer wall of the masonry block, and perform contour limiting and verticality calibration on the masonry block. S2. The height of the first and second limiting plates is raised synchronously layer by layer according to the masonry height. Through the mutual insertion and cooperation of the pin column and the pin hole, the synchronous locking and unlocking of the horizontal slide and the vertical slide are realized. S3. The material transport trolley enables the aerial sliding and transfer of building materials such as bricks and mortar, replacing the traditional manual bending and carrying and layer-by-layer material transfer method. This greatly reduces the labor intensity of workers and improves the efficiency of material transfer. The working height of the construction platform can be flexibly adjusted according to the real-time height of the masonry to adapt to the construction needs of different masonry layer heights.

[0014] In summary, this application includes at least one of the following beneficial technical effects: By forming a standardized masonry outline enclosure with mutually perpendicular first and second limiting plates, the outline of the building base can be accurately positioned before construction. During the masonry process, the bricks are laid in close contact with the surfaces of the first and second limiting plates, which can effectively prevent problems such as brick offset, tilting, and misalignment. This accurately ensures the external dimensions, verticality, and mortar uniformity of the manholes and retaining walls. It also effectively improves the overall integrity, compressive and shear resistance of the masonry structure, avoiding potential quality problems such as manhole cracking, wall deformation, pipeline leakage, and road settlement from the source, and significantly improving the construction quality and service life of municipal manhole projects. The horizontal and vertical sliding components enable the first and second limiting plates to slide horizontally and adjust vertically. This allows for adaptability to square, rectangular, and polygonal manholes and retaining wall construction of different specifications and dimensions, overcoming the limitations of traditional fixed auxiliary structures with poor versatility. Furthermore, the height of the first and second limiting plates can be raised layer by layer in sync with the masonry construction, achieving continuous limiting guidance from base construction to topping-out, solving the shortcomings of traditional static positioning in high-rise masonry construction and ensuring consistent masonry precision throughout the process. This quantitative and precise adjustment further enhances the standardization of construction. The linkage fixing component can achieve simultaneous locking and unlocking of the horizontal and vertical slides in a single operation, completing bidirectional positioning and fixing in one step. This eliminates the redundant steps of locking and unlocking in stages, greatly simplifying the construction operation process and reducing the time spent on adjustment and fixing. At the same time, it eliminates the problems of missing locks, incomplete locking, and loosening on one side when operating manually in stages, improving the convenience of construction operation and further ensuring the stability of masonry accuracy. The working height of the construction platform can be flexibly adjusted according to the real-time height of the masonry work, adapting to the construction needs of different masonry layer heights, replacing the traditional method of temporarily erecting scaffolding and raising the work height; the working height is easy to adjust and has strong stability, effectively improving the safety and comfort of high-altitude masonry work, realizing the integrated functions of limiting, leveling, material transportation and climbing operations, greatly improving the overall practicality of the device.

[0017] The present application will be further described in detail below with reference to the accompanying drawings.

[0018] This application discloses an auxiliary device for the construction of municipal utility manholes.

[0019] Reference Figure 1 , Figure 2The auxiliary device for the construction of municipal utility manholes includes multiple upright columns 1 placed in pairs facing each other, and steel structure sunshade frames 2 fixed to the top of each upright column 1 by steel wire ropes and fasteners. The upright columns 1 are vertically arranged, and lateral sliding components 3 are installed between adjacent upright columns 1 on the front and rear sides. The lateral sliding components 3 on the left and right sides are symmetrically arranged, and longitudinal sliding components 4 are installed on the lateral sliding components 3.

[0020] like Figure 2 , Figure 3 As shown, the transverse sliding assembly 3 includes a transverse slide rail 30 that is horizontally fixed between the two side columns 1, and a transverse slide block 31 that is slidably mounted on the transverse slide rail 30 in the horizontal direction. Multiple sets of rollers that are rotatably positioned on the upper and lower sides of the transverse slide rail 30 are rotatably disposed on the transverse slide block 31. The rollers are used to reduce the friction force experienced by the transverse slide block 31 during sliding, thereby enabling the transverse slide block 31 to slide more smoothly.

[0021] like Figure 3 , Figure 4 as well as Figure 5 As shown, the longitudinal sliding assembly 4 includes a vertical slide rail 40 fixedly mounted on a transverse slide block 31, and a longitudinal slide block 41 slidably mounted on the vertical slide rail 40 along the vertical direction. A first limiting plate 5 and a second limiting plate 6 are mounted on the bottom of the longitudinal slide block 41. The first limiting plate 5 is horizontally fixed between the opposing longitudinal slide blocks 41 on the left and right sides, and the second limiting plates 6 are oppositely arranged on the left and right sides of the first limiting plate 5. The two second limiting plates 6 slide horizontally along the length direction of the first limiting plate 5, and the first limiting plate 5 and the second limiting plate 6 are perpendicular to each other. A bidirectional screw 43 is rotatably mounted on the top of the first limiting plate 5. The length of the bidirectional screw 43 is along the sliding direction of the second limiting plate 6 on the first limiting plate 5. The second limiting plates 6 are symmetrically arranged at the left and right ends of the bidirectional screw 43, and the left and right ends of the bidirectional screw 43 are symmetrically provided with reverse threads. The two second limiting plates 6 pass through and are threadedly connected to the bidirectional screw 43. By rotating the bidirectional screw 43, the second limiting plates 6 on both sides can be driven to move in a direction that is closer to or further away from each other.

[0022] like Figure 3 , Figure 4 as well as Figure 5 As shown, the lateral sliding assembly 3 is used to drive the first limiting plate 5 and the second limiting plate 6 to slide back and forth in the horizontal direction, and the longitudinal sliding assembly 4 is used to drive the first limiting plate 5 and the second limiting plate 6 to rise and fall in the vertical direction. Each set of first limiting plates 5 and second limiting plates 6 together encloses the masonry construction area. The first limiting plates 5 and second limiting plates 6 are used to fit against the outer wall of the masonry block, limiting the block's outline and calibrating its verticality. They also rise and fall layer by layer with the masonry height to adapt and complete the masonry guidance and limiting.

[0023] A standardized masonry outline enclosure is formed by the mutually perpendicular first limiting plate 5 and second limiting plate 6. Before construction, the outline of the building base can be accurately positioned. During construction, the bricks are laid in close contact with the surfaces of the first limiting plate 5 and second limiting plate 6, effectively preventing problems such as brick offset, tilting, and misalignment. This precisely ensures the external dimensions of the manhole and retaining wall, the verticality of the wall, and the uniformity of mortar joints. It effectively improves the overall integrity, compressive and shear strength of the masonry structure, avoiding potential quality problems such as manhole cracking, wall deformation, pipe leakage, and road settlement from the source, significantly improving the construction quality and service life of municipal manhole projects.

[0024] like Figure 4 , Figure 6 As shown, two sets of load-bearing frames 7 are detachably assembled between the left and right transverse slide rails 30, and the two sets of load-bearing frames 7 are erected above the masonry construction area. The left and right sides of the load-bearing frames 7 are inserted and limited on their respective transverse slide rails 30 from top to bottom, and the load-bearing frames 7 are slidably arranged on the transverse slide rails 30 along the length of the transverse slide rails 30.

[0025] like Figure 5 , Figure 6 As shown, multiple sets of locking members 42 are fixedly installed on the side of the longitudinal slide 41 facing the load-bearing frame 7. The locking members 42 are arranged evenly and sequentially along the sliding direction of the longitudinal slide 41 on the vertical slide rail 40. The load-bearing frame 7 is equipped with a linkage fixing assembly 70. When the locking member 42 is inserted into the linkage fixing assembly 70, the linkage fixing assembly 70 locks the transverse slide 31 onto the transverse slide rail 30 to limit the horizontal sliding of the transverse slide 31 on the transverse slide rail 30. At the same time, the linkage fixing assembly 70 can also lock the longitudinal slide 41 onto the vertical slide rail 40 to limit the downward sliding of the longitudinal slide 41.

[0026] The horizontal sliding component 3 and the vertical sliding component 4 enable the first limiting plate 5 and the second limiting plate 6 to slide horizontally and be raised and lowered vertically. On one hand, this adapts to the construction of square, rectangular, and polygonal manholes and retaining walls of different specifications and dimensions, overcoming the limitations of traditional fixed auxiliary structures with poor versatility. On the other hand, the height of the limiting plates can be raised synchronously layer by layer according to the masonry height, achieving continuous limiting guidance from the base construction to the capping construction. This solves the problem that traditional static positioning cannot adapt to high-rise masonry, ensuring consistent masonry accuracy throughout the process. This quantitative and precise adjustment further improves the standardization of construction.

[0027] like Figure 5 , Figure 6As shown, the linkage fixing assembly 70 includes a fixing seat 700 that is slidably disposed on the top of the load-bearing frame 7 along the longitudinal direction. A pin post 701 is fixedly disposed on the fixing seat 700 for insertion into the pin hole 300 of the transverse slide rail 30 from top to bottom. The pin holes 300 are arranged evenly at intervals along the length direction of the transverse slide rail 30.

[0028] like Figure 5 , Figure 6 As shown, a trigger plate 702 is also fixedly installed on the fixed base 700, located on the lifting path of the adjacent locking member 42. When the locking member 42 on the same layer is mounted above the trigger plate 702, the longitudinal slide 41 will push the fixed base 700 under its own weight to press the pin 701 downward and fix it in the corresponding pin hole 300. Through the mutual insertion and cooperation between the pin 701 and the pin hole 300, the sliding of the transverse slide 31 on the transverse slide rail 30 can be restricted.

[0029] like Figure 4 , Figure 5 , Figure 6 As shown, the linkage fixing assembly 70 also includes a return spring 703 disposed on the top of the load-bearing frame 7. The return spring 703 is limited within the hollow sleeve at the top of the load-bearing frame 7, and extends and retracts along the sliding direction of the fixing seat 700. A lifting rod is integrally formed on the fixing seat 700 and is slidably disposed within the sleeve in the vertical direction. The return spring 703 is located at the bottom of the lifting rod and is used to push the lifting rod upward, so that the fixing seat 700 remains in an upward-lifted state without external force until the pin post 701 separates from the pin hole 300.

[0030] The linkage fixing component 70 can simultaneously lock and unlock the transverse slide 31 and the longitudinal slide 41 in a single operation, completing bidirectional positioning and fixing in one step. This eliminates the redundant steps of locking and unlocking in stages, greatly simplifying the construction process and reducing the time spent on positioning and fixing. At the same time, it eliminates the problems of missed locking, incomplete locking, and loosening on one side that occur during manual step-by-step operation, improving the convenience of construction operations and further ensuring the stability of masonry accuracy.

[0031] like Figure 6 , Figure 7As shown, a material transport trolley 8 is slidably mounted on the load-bearing frame 7. A connecting rod 80 is detachably installed on the material transport trolley 8. A material transport basket 800 for placing building materials is fixedly assembled at the bottom of the material transport trolley 8 via the connecting rod 80. A vertically oriented suspension member 81 is detachably installed at the bottom of the material transport basket 800 via bolts. Hanging holes 82 are through the suspension member 81 and are arranged at intervals along the length of the suspension member 81. A construction platform 83 is detachably installed on the suspension member 81 via the hanging holes 82. The construction platform 83 is a flat load-bearing platform and is detachably suspended and fixed to the suspension member 81 by fasteners, allowing personnel to stand and work independently.

[0032] The material transport trolley 8 enables aerial sliding and transfer of building materials such as bricks and mortar, replacing the traditional manual bending and layer-by-layer material handling method. This significantly reduces the labor intensity of workers, improves material transfer efficiency, and avoids the time-consuming and laborious problem of transporting materials back and forth. Simultaneously, relying on the suspension components 81 and multiple sets of hanging holes 82 integrated into the material transport basket 800, the construction platform 83 can be detachably suspended and installed. The working height of the construction platform 83 can be flexibly adjusted according to the real-time masonry height, adapting to the construction needs of different masonry layer heights, replacing the traditional method of temporarily erecting scaffolding and raising the work platform. The convenient adjustment of the working height and strong stability effectively improve the safety and comfort of high-altitude masonry operations, achieving integrated functions of limiting, leveling, material transport, and high-altitude operations, greatly enhancing the overall practicality of the device.

[0033] This application discloses a construction method for an auxiliary device for the construction of municipal utility pipe wells. The method utilizes the aforementioned auxiliary device for the construction of municipal utility pipe wells, and the technical solution is as follows: S1. Adjust the positions of the first limiting plate and the second limiting plate to form a masonry construction area by enclosing the area, so that the first limiting plate and the second limiting plate are in contact with the outer wall of the masonry block, and perform contour limiting and verticality calibration on the masonry block. S2. The height of the first and second limiting plates is raised synchronously layer by layer according to the masonry height. Through the mutual insertion and cooperation of the pin column and the pin hole, the synchronous locking and unlocking of the horizontal slide and the vertical slide are realized. S3. The material transport trolley enables the aerial sliding and transfer of building materials such as bricks and mortar, replacing the traditional manual bending and carrying and layer-by-layer material transfer method. This greatly reduces the labor intensity of workers and improves the efficiency of material transfer. The working height of the construction platform can be flexibly adjusted according to the real-time height of the masonry to adapt to the construction needs of different masonry layer heights.

[0034] The implementation principle is as follows: A standardized masonry outline is formed by the mutually perpendicular first limiting plate 5 and second limiting plate 6. Before construction, the outline of the building's base can be accurately positioned. During construction, the bricks are laid in close contact with the surfaces of the first limiting plate 5 and second limiting plate 6, effectively preventing problems such as brick offset, tilting, and misalignment. This precisely ensures the external dimensions of the manhole and retaining wall, the verticality of the wall, and the uniformity of the mortar joints. It effectively improves the overall integrity of the masonry structure and its compressive and shear resistance, avoiding potential quality problems such as manhole cracking, wall deformation, pipe leakage, and road settlement from the source, significantly improving the construction quality and service life of municipal manhole projects.

[0035] The horizontal sliding component 3 and the vertical sliding component 4 enable the first limiting plate 5 and the second limiting plate 6 to slide horizontally and be raised and lowered vertically. On one hand, this adapts to the construction of square, rectangular, and polygonal manholes and retaining walls of different specifications and dimensions, overcoming the limitations of traditional fixed auxiliary structures with poor versatility. On the other hand, the height of the first limiting plate 5 and the second limiting plate 6 can be raised synchronously layer by layer according to the masonry height, achieving continuous limiting guidance from the base construction to the topping-out construction. This solves the problem that traditional static positioning cannot adapt to high-rise masonry, ensuring consistent masonry accuracy throughout the process. This quantitative and precise adjustment further improves the standardization of construction.

[0036] The linkage fixing component 70 can simultaneously lock and unlock the transverse slide 31 and the longitudinal slide 41 in a single operation, completing bidirectional positioning and fixing in one step. This eliminates the redundant steps of locking and unlocking in stages, greatly simplifying the construction process and reducing the time spent on positioning and fixing. At the same time, it eliminates the problems of missed locking, incomplete locking, and loosening on one side that occur during manual step-by-step operation, improving the convenience of construction operations and further ensuring the stability of masonry accuracy.

[0037] The working height of the construction platform 83 can be flexibly adjusted according to the real-time height of the masonry work, adapting to the construction needs of different masonry layer heights, replacing the traditional method of temporarily erecting scaffolding and raising the work level. The working height is easy to adjust and highly stable, effectively improving the safety and comfort of high-altitude masonry operations. It realizes integrated functions of limiting, leveling, material transportation, and climbing operations, greatly enhancing the overall practicality of the device.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
