In the field of civil engineering, soft foundation treatment is a key link to ensure the stability and bearing capacity of the foundation, especially in areas with complex geological conditions. The cost and efficiency of soft substrate treatment have a direct impact on the smooth running of the entire project. This article will delve into the cost factors of soft foundation treatment engineering and provide a series of standards for reference.
The ** of soft foundation treatment works varies depending on the construction method, material type, and regional differences. The ** of mud pump dredging is about 4 5 yuan per cubic meter, while the ** of excavator removing silt is 7 12 yuan per cubic meter. The sand cushion and the gravel cushion are similar, about 55 60 yuan per cubic meter. The ** of throwing and filling flake stone is 45-50 yuan per cubic meter.
The ** of the cement mixing pile (500mm) is 9 11 yuan per meter, while the ** of the single-pipe high-pressure jet grouting machine (500mm) is 50 60 yuan per meter. The ** of the single-tube high-pressure jet sprayer (600mm) is slightly higher, about 55-65 yuan per meter. Plain concrete pile (50cm) ** at 50 60 yuan per meter. Static pressure or driven into the pile (outlet) of ** at 13 18 yuan per meter. Sand pile, gravel pile (80cm) ** at 16 18 yuan per meter.
Plastic drainage boards, geocells, geomesh mats and geogrids are similar, about 09~1.2 yuan per meter. The ** of composite geomembrane (including geotextile) is also 09~1.2 yuan per meter. The ** of the bagged sand well is in 15 2 yuan per meter. Long spiral CFG pile (50cm) ** at 12 18 yuan per meter. CFG pile cap concrete ** at 45 55 yuan per cubic meter. CFG pile slab concrete ** at 55 65 yuan per cubic meter. CFG pile slab and pile cap reinforcement are 400 420 yuan per ton.
These standards reflect the complexity and labor intensity of soft foundation treatment projects. When determining the cost of soft foundation treatment projects, it is necessary to comprehensively consider factors such as the selection of construction methods, the treatment of materials and environmental protection. Reasonable cost estimation and efficient management are essential to ensure the safety, quality and progress of the project. Engineers and project managers should fully understand the cost factors of soft foundation treatment engineering, and formulate a reasonable cost budget based on market standards and industry standards. At the same time, pay attention to safety measures and environmental protection requirements, optimize the construction plan, so as to improve the efficiency of soft foundation treatment projects. Through precise cost control and scientific management, we are able to lay a solid foundation for the successful implementation of soft foundation treatment projects. construction site
