Underneath the city, there is a group of unsung laborers, who, in a damp, dark, and cramped space, build the infrastructure for our lives - the pipe network project. This is a vital but little-known task that affects the functioning of the city and the quality of life of thousands of households. Today, what I would like to share with you is the labor subcontracting guidance for the "pipeline foundation" part of the pipeline network project, which truly reflects the hard work of our workers.
First of all, let's take a look at the ** of manually digging trench earthwork. At a depth of less than 2 meters, the ** of the earthwork of the manual trench dug per cubic meter is 27$5. And at a depth of less than 4 meters, it is from 4 to 47$5. This is not only a physical requirement, but also a test of technique. The ** of excavator digging trench earthwork is relatively low, 11 yuan per cubic meter (pit side dumping) and 14 yuan (loading). This is due to the efficiency and cost of the machine.
When faced with hard rock, artificial forces are inadequate. It takes 42 yuan per cubic meter to dig trenches, which is not only the cost of labor, but also a challenge to technology and endurance. The excavation and shipment of construction waste is 34 yuan per cubic meter, which includes the cost of cleaning and disposal.
After the trench excavation is completed, the next step is to ram the fill. Man-machine cooperation trench ramming fill is 16 yuan per cubic meter, which is to ensure the stability and safety of the trench. Similarly, man-machine cooperation trench backfill yellow sand is 20 yuan per cubic meter, and yellow sand is used as a backfill material, which is essential for the long-term stable operation of pipelines.
The yellow sand cushion of the pipeline is 22 yuan per cubic meter, which is to provide good pipeline support and drainage performance. The concrete pipe base is 41 yuan per cubic meter, which ensures the firmness and stability of the pipeline. The pipeline base formwork is 82 yuan per cubic meter, and the pipe base reinforcement is 810 yuan per ton, which are all to create a durable and safe pipeline foundation.
The foundation pit soil nail wall support is 122 yuan per square meter, in order to ensure the safety of the construction process. The DN350 tube well is 420 yuan per meter, which is to ensure the smooth access of the pipeline and the normal water supply of the city.
These first-class guidance not only reflect the hard work of our workers, but also reflect our persistent pursuit of quality and safety to a certain extent. We hope to build high-quality and stable infrastructure with our own hands and contribute to the development of the city.
However, behind these ** is our unremitting efforts and dedication. In the damp and dark underground, we are suffering from physical exhaustion and psychological pressure, in order to ensure the smooth progress of the project, we are not afraid of hardships and stick to our posts. We hope that through our efforts, we will be respected and rewarded.
Here, I would like to appeal to all sectors of society for their attention and understanding. We are silently paying for the better tomorrow of the city, and hope that our labor can be recognized and respected. At the same time, we also hope that these labor subcontracting guidelines** can help us better plan and arrange our own work, and provide us with more protection.
Let's work together to contribute to the prosperity and development of the city. We are the most beautiful laborers, and our labor is the most respectable. Let's work together for a better tomorrow! construction site
