Description

Technical Field

[0001] This utility model belongs to the field of well construction engineering technology, and in particular relates to a modular frame structure for prefabricated wells. Background Technology

[0002] A well is a vertically installed tubular structure for drawing or protecting groundwater. It has a small diameter and a relatively large depth to facilitate the extraction of deep or shallow groundwater. It is a water supply and drainage facility used in industrial and agricultural production, urban areas, transportation, and national defense. When multiple wells are used side-by-side, a frame structure is required to reinforce them and ensure stable vertical installation.

[0003] The existing technical problems are as follows:

[0004] 1. Traditional well construction requires installing the well casing layer by layer, which is inefficient and carries high risks associated with working at height;

[0005] 2. The confined space of the well and the dense arrangement of the well pipes make bolted connections difficult and quality control challenging.

[0006] 3. On-site installation is easily affected by environmental factors, and the construction period is uncontrollable;

[0007] 4. If the manhole is relatively small and there are many manholes to install, it is difficult for installers to operate. If the pipe diameter is relatively large and the manhole openings in the building structure are narrow, there is a shortage of space inside the manhole. The manholes are crowded together, making it difficult to install each manhole individually. The installation time is long and it is difficult to eliminate safety and quality hazards in the process.

[0008] 5. The office building has many floors, and the prefabricated modular risers are quite heavy after being assembled externally, making on-site hoisting difficult;

[0009] 6. The prefabricated riser pipes for wells are quite heavy after assembly, making tower crane lifting and transportation difficult.

[0010] 7. Traditional frame structures are bulky, complex to disassemble and assemble, lack vibration reduction and cold bridge control designs, and are difficult to adapt to different pipe diameter combinations. Utility Model Content

[0011] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and solve the problems of low construction efficiency and poor safety of the existing modular frame structure for prefabricated wells.

[0012] The technical solution adopted by this utility model to solve its technical problem is: a modular frame structure for prefabricated manholes, including manholes, wherein multiple manholes are provided, and a pair of long steel bars and a pair of short steel bars are respectively fitted around the periphery of the multiple manholes. Adjacent long steel bars and short steel bars are connected by bolts. Multiple spacer steel bars are connected between two long steel bars by bolts. The spacer steel bars are located between two adjacent manholes. A pair of support plates are fitted onto the outer surface of the multiple manholes. Each support plate has a semi-circular receiving cavity at its inner end. The two support plates are connected by bolts.

[0013] In a preferred embodiment of this utility model, multiple support beams are bolted together at the lower ends of the two long steel bars, and each support beam is bolted to a support column at both ends.

[0014] In a preferred embodiment of this invention, each of the supporting columns is provided with a structural beam at its lower end, and the upper end of each structural beam is threadedly connected to the lower end of the adjacent supporting column with a stud.

[0015] In a preferred embodiment of this utility model, the upper ends of both the long and short steel bars are fixedly connected to support brackets, the support brackets are arranged around the periphery of the adjacent pipe shafts, and the inner end of the support brackets is in close contact with the outer wall of the pipe shaft.

[0016] In a preferred embodiment of this invention, a sleeve is fitted onto the outer surface of multiple wellbore pipes. The sleeve is located inside the space between two adjacent receiving cavities. The radius of the receiving cavity is equal to the radius of the adjacent sleeve ring. The sleeve and the support plate are located below the long steel bar, the spacer steel bar, and the short steel bar.

[0017] In a preferred embodiment of this invention, the structural beam is located at the lower end between two adjacent supporting columns on the same side of the outer end of the support plate, and the support plate is located at the lower end between the structural beams.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0019] The on-site processing and installation work inside the building were transferred to a specialized off-site factory for finished module processing. After the modules were transported to the site, they were hoisted as a whole into the corresponding holes in the manhole, and then fixed and installed on-site. The long and short steel bars have grooves at their outer ends, presenting a "U" shaped cross section. The grooves of the long and short steel bars are placed outward to make them fit tightly against the surface of the manhole. The reinforcing ribs on the rib plate assembly are bolted to the manhole. Vibration damping pads are used to separate the rib plate assembly seat plate from the channel steel, and they are firmly connected with bolts.

[0020] The upper end of the support beam is connected to the lower end between two long steel bars. The lower end of the support column is installed on the upper end of the corresponding structural beam. The stud connects the upper end of the structural beam with the lower end of the adjacent support column into one unit. The structural beam provides a horizontal support surface for the adjacent support column to support upwards. The lower end of the support column uses the adjacent structural beam as a fulcrum to lift the support beam upwards, thus completing the frame assembly process.

[0021] The main frame is made of No. 12 channel steel connected by bolts to form a rectangular frame with the slots facing outwards. The long side dimension is less than or equal to the size of the manhole opening (2620mm long and 650mm wide). Longitudinal reinforcing ribs are added inside the slots of the channel steel to increase the lifting stress strength. The frame and the manhole are connected by bolts through rib plate groups, and vibration damping pads are set in the middle to prevent loosening and shaking, thereby eliminating safety hazards.

[0022] The modular, layered design features a frame consisting of two layers. The upper layer uses long steel bars, spacer bars, and short steel bars to form a rectangular grid structure that wraps around the outside of each pipe shaft. The lower layer uses support plates and casings to wrap around the outside of the pipe shaft. Different sized cavities are provided to accommodate pipe shafts of different diameters for assembly. Support brackets provide additional reinforcement to the outer wall of the pipe shaft, ensuring a firm assembly. Prefabrication is done in units with a height of two layers (8.4m) or three layers (12.6m), which helps to improve the stability of the pipe shaft installation.

[0023] A unified plan for the on-site hoisting of electromechanical materials should be developed, and the usage time of tower cranes and elevators should be allocated. Refuge floors should be fully utilized, and the on-site material turnover areas and tool storage areas of various electromechanical subcontractors should be rationally arranged. The working time and duration of tower cranes and elevators should be flexibly and fully utilized to hoist materials to the turnover area within the electromechanical material and equipment floor in advance. Tower crane hoisting and wire rope traction should be used to hoist the pipe shafts from top to bottom, so that the pipe shafts are arranged side by side at the required installation positions. This helps to ensure that the items on the construction site are placed in an orderly and neat manner, so as to free up more space to accommodate the pipe shafts and facilitate the installation of each pipe shaft one by one.

[0024] The channel steel frame and the pipe shaft are connected by standardized rib plate groups to accommodate multiple pipe diameter combinations; the vibration damping pads and bolt fixing are designed in a coordinated manner to balance load-bearing capacity and thermal bridge control; longitudinal reinforcing ribs enhance the frame's resistance to deformation, with a hoisting safety factor of ≥2.1;

[0025] In summary, this device has a lightweight and simple structure, is easy to construct and disassemble, has high efficiency, short construction period, low labor intensity, good safety, is convenient for construction of pipe wells with different pipe diameters, and can be adapted to different pipe diameter combinations, making the construction period controllable.

[0037] Please see Figure 1-10This utility model provides a technical solution: a modular frame structure for prefabricated manholes, including manhole 10s, of which multiple manholes 10 are provided. A pair of long steel bars 1 and a pair of short steel bars 3 are respectively fitted around the periphery of each manhole 10. Adjacent long steel bars 1 and short steel bars 3 are connected by bolts. Multiple spacer steel bars 2 are bolted between two long steel bars 1, and the spacer steel bars 2 are located between two adjacent manholes 10. A [missing information - likely a type of steel bar] is fitted onto the outer surface of the multiple manholes 10. Each pallet 8 has a semi-circular receiving cavity 11 at its inner end, and the two pallets 8 are connected by bolts. Multiple support beams 5 are bolted together at the lower ends of the two long steel bars 1, and each support beam 5 has a support column 4 bolted to both ends at its lower end. Structural beams 6 are installed at the lower ends of the support columns 4, and studs 7 are threaded between the upper ends of the structural beams 6 and the lower ends of the adjacent support columns 4. Support supports 12 are fixedly connected to the upper ends of both the long steel bars 1 and the short steel bars 3. The support bracket 12 is arranged around the perimeter of adjacent pipe shafts 10, with its inner end in close contact with the outer wall of the pipe shaft 10. Multiple pipe shafts 10 are fitted with sleeves 9 on their outer surfaces. The sleeves 9 are located inside the spacers between two adjacent receiving cavities 11, the radius of which is equal to the radius of the adjacent sleeves. The sleeves 9 and the support plate 8 are located below the long steel bar 1, the spacer steel bar 2, and the short steel bar 3. The structural beam 6 is located at the lower end between two adjacent supporting columns 4 on the same side of the outer end of the support plate 8, and the support plate 8 is located at the lower end between the structural beams 6. The on-site processing and installation work inside the building were transferred to a specialized off-site factory for prefabricated modular processing. The required components were formed, including long steel bars 1, spacer steel bars 2, short steel bars 3, support columns 4, bracket beams 5, structural beams 6, support plates 8, sleeves 9, pipe shafts 10, receiving cavities 11, and support brackets 12. Among them, studs 7 were obtained by purchasing off-the-shelf parts. All components were not made on the construction site to avoid air pollution and achieve the effect of modular production of the frame structure.

[0038] After the finished modules are transported to the site, they are hoisted as a whole into the corresponding holes of the manholes, and then fixed and installed on site. All manholes that require the installation of combined risers are arranged using BIM technology to determine the location of manhole 10, ensuring the operation of installation personnel to the greatest extent possible. When preparing and submitting the progress plan, the hoisting plan for equipment and materials consumption is submitted simultaneously. A unified on-site hoisting plan for electromechanical materials is prepared, and the usage time of tower cranes and elevators is allocated. Refuge floors are fully utilized, and the on-site material turnover areas and tool storage areas of various electromechanical subcontractors are reasonably arranged. The working time and duration of tower cranes and elevators are flexibly and fully utilized to hoist materials to the turnover area on the electromechanical material and equipment floor in advance. This helps to ensure that the items on the construction site are placed in an orderly and neat manner, so as to free up more space to accommodate manhole 10 and facilitate the installation of each manhole 10 one by one.

[0039] Before the main structure is capped, the materials assembled for the prefabricated manhole are hoisted to the highest floor of the current structure using a tower crane. Then, hoists are used to hoist and install the prefabricated modular risers. The channel steel frame and the manhole 10 are connected by standardized rib plate assemblies, which are suitable for multi-diameter combinations. The reinforcing ribs on the rib plate assembly are bolted to the manhole 10. Vibration-damping rubber pads are used to separate the rib plate assembly base plate from the channel steel and are firmly bolted together. The vibration-damping rubber pads and bolt fixing are designed in a coordinated manner to balance load-bearing capacity and thermal bridge control. Longitudinal reinforcing ribs are added inside the channel steel groove to improve the hoisting stress strength. The frame and manhole 10 is connected by bolts through rib plate groups, with vibration damping pads in the middle. The vibration damping pads are used for heat insulation and prevent heat transfer and sudden temperature changes at the connection points, avoiding loosening and shaking, thus eliminating safety hazards. Longitudinal reinforcing ribs are used to improve the frame's resistance to deformation. The hoisting safety factor is ≥2.1. Tower crane hoisting is used, and steel wire ropes are used to pull the pipe shaft 10 from top to bottom, so that the pipe shaft 10 are arranged side by side at the required installation position. The main frame is made of No. 12 channel steel connected by bolts to form a rectangular frame with the slots facing outwards. The long side dimension is ≤ the pipe shaft hole size (length 2620mm, width 650mm).

[0040] The spacer steel strips 2, long steel strips 1, and short steel strips 3 are spliced ​​together to form a rectangular grid frame structure (see the image below for the effect of the spliced ​​rectangular grid structure). Figure 1 As shown), the long steel bar 1 and the short steel bar 3 fix the pipe shaft 10. The outer ends of the long steel bar and the short steel bar have grooves, presenting a "U" shaped cross section. The grooves of the long steel bar and the short steel bar are placed outwards, and the inner ends of the long steel bar and the short steel bar are flat to fit tightly against the outer wall of the pipe shaft 10, so as to fit tightly against the surface of the pipe shaft 10. The sleeve 9 is inserted into the surface of each corresponding pipe shaft 10, and then the support plate 8 is clamped on the surface of the pipe shaft 10. The pipe shaft 10 is placed in the receiving cavity 11, and the support plate 8 is in close contact with the pipe shaft 10, supporting the pipe shaft 10 stably. The upper end of the support beam 5 is connected to the lower end between the two long steel bars 1, and the upper end of the support column 4 is connected to the support beam 5. The lower ends of the support beam 5 are connected on both sides, and the lower end of the support column 4 is installed on the upper end of the corresponding structural beam 6. The stud 7 connects the upper end of the structural beam 6 to the lower end of the adjacent support column 4 into one unit. The structural beam 6 provides a horizontal support surface for the adjacent support column 4 to support upwards. The lower end of the support column 4 uses the adjacent structural beam 6 as a fulcrum to lift the support beam 5 upwards, so that the two long steel bars 1 are lifted upwards. The two long steel bars 1 lift multiple short steel bars 3 and multiple spaced steel bars 2 upwards, so that the frame is installed stably. The frame keeps each pipe shaft 10 in a stable and upright position. The frame can be disassembled by reversing the above installation steps.

[0041] The modular, layered design features a frame consisting of two layers. The upper layer uses long steel bars 1, spacer bars, and short steel bars 3 to form a rectangular grid structure that wraps around the outside of each pipe shaft 10. The lower layer uses support plates 8 and casings 9 to wrap around the outside of the pipe shaft 10. Different sized cavities 11 are provided to accommodate pipe shafts 10 of different diameters for assembly. Support brackets 12 provide auxiliary reinforcement and support to the outer wall of the pipe shaft 10, ensuring a firm assembly of the pipe shaft 10. The system is prefabricated in units with a height of two layers (8.4m) or three layers (12.6m).

[0042] This device has a lightweight and simple structure, and features easy construction, simple assembly and disassembly, high efficiency, short construction period, low labor intensity, good safety, and is convenient for construction of pipe wells 10 with different pipe diameters. It can adapt to different pipe diameter combinations, making the construction period controllable.
