What are the special treatment methods and precautions for the construction of lime kiln foundation
The construction of lime kiln foundation is related to the stability and safety of the entire kiln body, requiring special treatment methods and attention to many matters.
Special handling methods
For weak foundations, the replacement method can be used to excavate the weak soil layer, replace it with high-strength and low compressibility materials such as sand, gravel, and lime soil, and compact them to improve the bearing capacity of the foundation. If the groundwater level is high, a precipitation well can be set up to lower the groundwater level in advance and avoid the foundation from being soaked in water during construction. At the same time, waterproof rolls are laid at the bottom of the foundation to prevent groundwater infiltration and erosion of the foundation. For large lime kilns, pile foundations can be set up to reduce uneven settlement and transfer loads to deep stable soil layers.
precautions
Before construction, it is necessary to conduct a detailed geological survey to accurately grasp the geological conditions and provide a basis for the construction plan. Strictly control the quality of raw materials, and ensure that cement, sand and gravel meet the design requirements. When pouring concrete, it is necessary to compact it layer by layer to avoid defects such as honeycombing and rough surfaces. During the basic maintenance period, the surface should be kept moist to prevent drying and cracking. In addition, it is necessary to arrange the construction sequence reasonably, avoid cross operation interference, and ensure construction safety and quality.
