BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is the overall flow chart of the present invention. DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The present invention provides an outdoor pipeline construction method for an old residential area, which specifically comprises the following steps: S1. Modular pipeline processing and identification. HDPE double-wall corrugated plastic pipes are used as modular pipelines. The length of each pipeline module is 3m and the weight is controlled within 45kg, which is convenient for manual handling and mechanical lifting. The outdoor rainwater pipeline is cut into modules of standard length. Each module is quickly assembled and connected through connectors and rubber sealing rings. A unique QR code is set for each pipeline module as an identification code. The identification code is read by a handheld scanning device to record the source, installation location and usage status of the pipeline module; Specifically, in this step, HDPE double-wall corrugated plastic pipe is selected as the material of modular pipe because of its light weight, high strength, corrosion resistance, wear resistance, good flexibility, easy installation and other characteristics. This material not only meets the functional requirements of rainwater pipes, but also is easy to process into modules of standard length. The outdoor rainwater pipes are cut according to the predetermined length to form standardized pipe modules, which can simplify the construction process and improve construction efficiency. At the same time, it is convenient for the transportation, storage and assembly of pipe modules. Each pipe module is connected by a special connector and a rubber sealing ring. This connection method is not only simple and fast, but also can ensure the sealing between pipes and prevent rainwater leakage. A unique QR code is set for each pipe module as an identification code. The QR code contains relevant information of the pipe module, such as source, installation location and usage status. This identification method is convenient for management and tracking during the construction process. The QR code on the pipe module is read by a handheld scanning device, and the read information is entered into the construction management system or database, which can realize the full life cycle management of the pipe module, including procurement, transportation, installation, maintenance and replacement.

[0020] S2. UAV measurement and line laying: UAVs are equipped with high-definition cameras, laser radars and infrared sensors to conduct aerial measurements of construction sites. Based on the high-definition images and video data taken by the UAVs, three-dimensional model data of the outdoor terrain and pipeline layout of the old residential area are generated. Combined with a computer control system, line laying is automatically performed based on the three-dimensional model data to ensure line laying accuracy; Specifically, in this step, the high-definition camera is used to capture high-definition images and video data of the construction site. These data are the basis for generating a three-dimensional model. The laser radar achieves high-precision terrain and pipeline layout measurement by emitting laser beams and receiving reflected light signals. The laser radar can provide detailed terrain data and ground object models, which has great advantages for measuring complex terrain. The infrared sensor is used to detect potential heat sources or abnormal areas at the construction site, and assist in identifying pipeline layout and potential problems. Based on the high-definition images and video data taken by the drone, combined with the measurement data of the laser radar and infrared sensor, professional software and algorithms are used to generate three-dimensional model data of the outdoor terrain and pipeline layout of the old community. The three-dimensional model data can intuitively display the terrain, pipeline layout and surrounding environment of the construction site, providing an accurate basis for laying out the line. The generated three-dimensional model data is imported into the computer control system. The computer control system automatically plans the laying-out path according to the three-dimensional model data, and controls the laying-out equipment to lay out the line according to the planned path. The laying-out accuracy and efficiency are ensured through precise computer control and algorithm optimization.

[0021] S3, pipe trench excavation, according to the data measured by the drone, the excavation path and depth are mined, and the excavator equipped with depth sensors, width sensors and tilt sensors is used to automatically excavate the pipe trench. The sensors monitor the excavation depth and width, as well as the tilt angle of the excavator in real time to ensure the excavation accuracy and safety; Specifically, in this step, a drone is used to take aerial photos of the excavation area and collect terrain data. Through data analysis, the optimal path and depth of the trench are determined to ensure that the excavation of the trench meets the engineering requirements and avoids underground obstacles. The depth sensor is installed on the excavator to monitor the excavation depth in real time to ensure that the excavation depth meets the design requirements and avoids over-excavation or under-excavation. The width sensor monitors the excavation width to ensure that the width of the trench meets the requirements for laying pipelines. The tilt sensor monitors the inclination angle of the excavator to ensure that the excavator remains stable during operation and prevents safety accidents caused by excessive inclination angles. The excavator performs automated operations based on the data measured by the drone and the information monitored in real time by the sensor. The driver can clearly see the excavation depth and excavation direction through the display and control terminal in the cab, thereby controlling the operation of the excavator more accurately.

[0022] S4. Pipeline laying and inspection well construction: Lay the processed modular pipelines according to the layout position to ensure that the pipelines are tightly connected and accurately positioned. Use concrete modular inspection wells for construction and conduct quality inspections and tests to ensure the strength and sealing of the inspection wells. Specifically, in this step, the processed modular pipes are laid one by one according to the layout position to ensure the accuracy of the position of the pipes on the predetermined path. The pipes need to be tightly connected to ensure the smooth flow of the fluid in the pipes and prevent leakage. Concrete modular inspection wells are used for construction. Concrete modular inspection wells have the advantages of high strength and convenient construction, and can adapt to various complex construction environments. During the construction process, operations must be carried out in accordance with relevant specifications and standards to ensure the quality and safety of the inspection wells. Quality inspection and testing are carried out on the laid pipes and constructed inspection wells to verify whether the key performance of the pipes and inspection wells, such as strength and sealing, meet the design requirements. Quality inspection and testing usually include appearance inspection, dimension measurement, and pressure testing.

[0023] S5. Pipeline water-tightness test: Conduct a water-tightness test on the completed pipelines. Inject water into the pipelines and observe whether there is leakage to ensure the pipeline tightness. Record the test results, mark the leakage parts and repair them. Specifically, in this step, the principle of the pipeline water-tightness test is based on the Pascal principle, that is, the pressure of the liquid in a closed container on the container wall and the immersed object is proportional to the liquid depth and has nothing to do with the shape of the container. In the water-tightness test, a certain amount of water is injected into the laid pipeline and a certain hydrostatic pressure is applied. If there is a leak in the pipeline, the water at the leak will seep out due to the pressure difference, forming a visible leakage mark, or causing the water level to drop. By observing the leakage phenomenon, the sealing performance of the pipeline can be judged; Specifically, fill the test pipe section with water, and the water level should reach a certain height above the top of the upstream pipe of the test section (such as 2 meters), and soak for a period of time (such as 1-2 days) to fully check the sealing of the pipeline and the interface. After the pipeline is filled with water, start recording the test data. Start timing when the test water head reaches the specified water head, observe the water seepage in the pipeline, and the water seepage observation time must not be less than the specified time (such as 30 minutes). During this period, water should be continuously added to the test pipeline to keep the test water head constant. The seepage amount is calculated according to the drop value of the water level in the well, and compared with the specified allowable seepage amount. When the measured seepage amount is less than or equal to the allowable seepage amount, the test is qualified; otherwise, the test is unqualified.

[0024] S6. Backfilling: Use intelligent backfilling equipment equipped with a vibration compaction device and a material level sensor to evenly place the backfill material, and ensure the density and uniformity of the backfill material through vibration compaction. Monitor the amount of backfill material placed and the degree of compaction in real time to ensure the quality of backfilling; Specifically, in this step, the backfilling equipment integrates a vibration compaction device and a material level sensor, which can achieve uniform delivery and compaction of the backfill material. The material level sensor is used to monitor the delivery amount of the backfill material in real time to ensure that the supply of the backfill material is sufficient and not excessive. The vibration compaction device generates high-frequency vibrations to cause relative displacement and rearrangement between the backfill material particles. Under the action of the vibration force, the gaps between the backfill material particles are gradually reduced, thereby achieving a compaction effect. The intelligent backfilling equipment monitors the delivery amount of the backfill material in real time through the material level sensor to ensure the continuity and stability of the backfilling operation. At the same time, the equipment also monitors the degree of compaction in real time through the control system of the vibration compaction device to ensure that the density and uniformity of the backfill material meet the design requirements.

[0025] S7. Real-time monitoring and feedback, including soil deformation, groundwater level, pipeline displacement, construction noise and dust. Sensors and monitoring systems are used to monitor construction quality and safety status in real time. Monitoring data is transmitted to the construction management center in real time via wireless networks and processed and analyzed by data analysis software. Once an abnormal situation is found, an alarm is immediately issued and treatment suggestions are provided; Specifically, in this structure, a variety of sensors are arranged at the construction site, such as soil deformation sensors, groundwater level sensors, pipeline displacement sensors, noise monitoring sensors and dust monitoring sensors. These sensors can monitor the key parameters of soil deformation, groundwater level changes, pipeline displacement, construction noise and dust concentration at the construction site in real time. The monitoring data is transmitted to the construction management center in real time through wireless networks (such as 4G / 5G, Wi-Fi, etc.). The monitoring data received by the construction management center is processed and analyzed by data analysis software. The data analysis software can use various algorithms and models to deeply mine and interpret the data, and extract useful information and rules. The data analysis software can set thresholds and early warning conditions, and perform real-time monitoring and anomaly detection of monitoring data. Once an abnormal situation is found, such as excessive soil deformation, abnormal increase in groundwater level, pipeline displacement out of range, construction noise or dust exceeding the standard, the data analysis software will immediately issue an alarm and provide corresponding processing suggestions.

[0026] S8. Environmental protection construction measures: install watering and dust reduction facilities in the construction area, carry out watering operations regularly to reduce dust pollution, classify and recycle construction waste to reduce waste pollution to the environment, use low-noise construction equipment to reduce the impact of construction noise on the surrounding environment, install noise monitoring equipment and dust monitoring equipment at the construction site to monitor construction noise and dust pollution in real time, and take corresponding control measures based on the monitoring results; Specifically, in this step, watering and dust reduction facilities are set up in the construction area. Through regular watering operations, the air humidity is increased, and the suspended particles in the air are moistened and settled, thereby reducing dust pollution. Construction waste is classified to distinguish between recyclables, hazardous waste, wet waste and dry waste. Recyclables are recycled, such as scrap steel, waste wood, and waste paper. Hazardous waste is specially treated to prevent it from polluting the environment. Wet and dry waste are properly handled to reduce their negative impact on the environment. Low-noise construction equipment is used, such as excavators and loaders with less noise, and the equipment is cleaned and emptied. Noise reduction devices such as silencers and shock absorbers are installed to reduce the generation and spread of construction noise. Noise monitoring equipment and dust monitoring equipment are set up at the construction site to monitor construction noise and dust pollution in real time. The noise monitoring equipment calculates the noise level by measuring the propagation speed and amplitude of sound waves in the air. The dust monitoring equipment measures the scattered light intensity of particulate matter in the air to calculate the dust concentration. According to the noise and dust monitoring results, corresponding control measures are taken. For example, when the noise or dust exceeds the standard, the construction equipment is adjusted in time, the frequency of watering is increased, and waste management is strengthened to reduce noise and dust pollution.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
