Description

Technical Field

[0001] This utility model relates to the technical field of construction protection devices for water supply pipe sockets, specifically a construction protection device for water supply pipe sockets. Background Technology

[0002] With the continuous improvement of the country's economic and infrastructure capabilities, building structures are becoming increasingly diverse. For example, there are more and more subway stations in bustling urban areas. The construction area is complex due to changes in traffic conditions, and the space for work scope, pipeline relocation and protection is limited. Therefore, the form of in-situ pipeline protection is being adopted more and more.

[0003] In a current infrastructure construction project, the line is approximately 24.5km long, with 16 stations and 17 sections, including 7 interchange stations. One method for protecting the water supply pipeline socket joints is being implemented at a station. This station is a three-story, double-span (partially triple-span) box-type structure, constructed using bored pile support and open-cut method. The DN500 water supply pipeline on the north side of the station's main structure is only 0.3m away from the station's capping beam structure, and there is a manhole in one section. According to the design drawings, the capping beam and retaining wall construction method uses a 60° slope excavation and slope shotcrete protection for the outer 20cm of the capping beam. This method is prone to disturbing and damaging the water supply pipeline, posing a significant construction risk on site. Therefore, a construction protection device for the water supply pipeline needs to be designed. Utility Model Content

[0004] The purpose of this utility model is to provide a construction protection device for water supply pipe sockets to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a construction protection device for a water supply pipe socket, comprising wooden beams and steel pipe columns. There are four wooden beams, two of which are parallel and clamp the water supply pipe one near the socket, and the other two are parallel and clamp the water supply pipe two near the spigot. There are four steel pipe columns, which are parallel and clamp the four wooden beams. The steel pipe columns are perpendicular to the water supply pipe one and water supply pipe two. The two steel pipe columns of the water supply pipe one are tightly bound together with reinforcing bars, and the two steel pipe columns of the water supply pipe two are also tightly bound together with reinforcing bars. The steel pipe columns are fixed in the soil.

[0007] As an improvement, the wooden beams are fixed to water supply pipe one and water supply pipe two by adhesive bonding, and the steel pipe column is fixed to water supply pipe one and water supply pipe two by adhesive bonding.

[0008] The advantages of this utility model compared with the prior art are as follows: by changing the traditional in-situ pipeline protection to steel pipe column support for pipeline protection construction, the pipeline protection requirements are guaranteed while avoiding problems such as pipelines affecting the construction difficulties of the station's main structure. This effectively reduces construction difficulty, ensures construction quality, and saves construction time. Attached Figure Description

[0022] This embodiment is combined with the appendix Figures 1 to 5 This paper provides a detailed description of a construction protection device for water supply pipe sockets.

[0023] This embodiment discloses a construction protection device for a water supply pipe socket, comprising wooden beams 1 and steel pipe columns 2. There are four wooden beams 1; two beams are parallel and clamp the water supply pipe 3 near its socket, and the other two beams are parallel and clamp the water supply pipe 4 near its spigot. There are four steel pipe columns 2, which are parallel and clamp the four wooden beams 1. The steel pipe columns 2 are perpendicular to the water supply pipe 3 and the water supply pipe 4. The two steel pipe columns 2 of the water supply pipe 3 are tightly bound together with steel bars 5, and the two steel pipe columns 2 of the water supply pipe 4 are also tightly bound together with steel bars 5. The steel pipe columns 2 are fixed in the soil.

[0024] The wooden beam 1 is fixed to the water supply pipe 3 and the water supply pipe 4 by bonding, and the steel pipe column 2 is fixed to the water supply pipe 3 and the water supply pipe 4 by bonding.

[0025] In practice, prior to construction, it is necessary to communicate with the design unit to review the construction process for the protection of the DN500 water supply pipe socket, and clarify the design form of pipeline protection. Typically, this type of pipeline protection involves in-situ suspension. The steel pipe column 2 support protection is a method adopted to ensure smooth subsequent structural construction of the station. After confirming the construction process, contact the manufacturer for the fabrication of the steel pipe column 2. The fabrication of the steel pipe column 2 should be carried out by a qualified manufacturer, who must provide qualified steel and welding inspection reports, as well as quality certificates.

[0026] Based on the actual site conditions, the protection of water supply pipe 1 (3) and water supply pipe 2 (4) should be subject to self-inspection and acceptance inspection by the property owner as required. This includes checking the steel pipe column 2 (appearance, type, model, specifications, verticality) and welds (length, width, thickness, seam, surface smoothness, etc.), and recording the findings. Construction can only proceed with steel pipe column 2 after it has passed inspection.

[0027] Before conducting measurement and positioning, the integrity, reliability, and accuracy of the measuring instruments and equipment should be checked, and the instrument appraisal certificate issued by the legal metrology unit should be reviewed and submitted to the supervision unit for review.

[0028] Verify the pipeline location map and related pipeline information provided by the property owner. If any markings are unclear, locations are uncertain, or damage is found, they should be verified and repaired promptly. Construction can only proceed after the locations have been stabilized.

[0029] The key to controlling the construction quality of steel pipe columns lies in the control of their position, elevation, and verticality. Different measures are taken to correct, adjust, and control these three points respectively.

[0030] Elevation control is fairly standard. After the steel pipe columns are installed, a total station will be used to check the elevation using the control points. The allowable elevation error range is 0 to -20 mm. In this project, the top elevation of the steel pipe columns is consistent, and the ground elevation does not vary much. Therefore, the appropriate length should be calculated and determined before construction.

[0031] For the protection construction of the water supply pipeline socket joints, four steel pipe columns, each 4.5m long, 159mm in diameter, and 5mm thick, are installed at the socket joints. Four φ32 threaded steel bars are installed at the top and bottom of the water supply pipe for secure connection. The steel pipe columns are embedded 3m below the bottom of the capping beam, with at least 20cm remaining above the top of the water supply pipe for welding the threaded steel bars. A monitoring point is set at each socket joint to monitor changes in the water supply pipe elevation. Excavation of the soil near the water supply pipe is carried out using a combination of manual and mechanical methods, with manual excavation used only for adjacent sections to prevent the water supply pipe from being exposed in the soil. Each excavation length does not exceed 12m. This patented method ensures the construction requirements of the main structure capping beam retaining wall while avoiding construction safety and control difficulties caused by the water supply pipe occupying space. It also provides better control over construction precision, ensures construction safety and quality, and shortens the construction period.

[0032] The construction task of this project is to protect the sockets of the water supply pipeline. The construction process includes earthwork excavation, steel pipe column installation, threaded steel welding, monitoring point layout, and capping beam construction. After the pipeline protection construction is completed, the sockets of the water supply pipeline need to be tested for leakage and tightness.

[0033] This construction technique focuses on addressing issues such as steel pipe column misalignment, weak welding, and pipeline damage during steel pipe column construction, which are difficult to adjust. By modifying the design in advance, including foundation treatment after excavation and controlling the construction time of the steel pipe columns, this technique ensures the construction quality of the steel pipe columns, avoids the aforementioned problems during construction, better controls construction precision, guarantees pipeline protection quality, and shortens the construction cycle.

[0034] During the process, a level, total station, and ultrasonic testing instrument were used to check and correct the elevation, pile position, and verticality of the steel pipe columns to ensure that the construction quality met the requirements.

[0035] The entire process is scientifically and rationally designed to ensure the feasibility, reliability, repeatability, and scalability of construction operations.

[0036] The construction period was shortened after adopting this technology. This effectively reduced the resource consumption during subsequent station structure construction.

[0037] This method provides valuable reference for similar pipeline protection projects, effectively reducing construction difficulty, facilitating precision control, and shortening the construction cycle. Steel pipe columns are installed at the socket joints, and threaded steel bars are used for secure connection at the top and bottom of the water supply pipe. A monitoring point is set at each socket joint to monitor changes in the water supply pipe elevation. Excavation near the water supply pipe is conducted using a combination of manual and mechanical methods, with manual excavation used only for adjacent pipes to prevent the pipe from being exposed. This approach ensures the requirements of the main structure's capping beam and retaining wall construction while avoiding construction safety and control difficulties caused by the water supply pipe occupying space. It also allows for better control of construction precision, guarantees construction safety and quality, and shortens the construction cycle.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
