泥浆护壁钻孔灌注桩适用于陆地或水域施工,可以在地下水位以下或地下水位以上的各种土层中成孔,也可在地质情况复杂、夹层多、风化不均、软硬变化较大的岩层中施工,并且不受季节气候的影响。单桩垂直承载力最大可达1000kN,可满足高、大、重型建筑和特大型桥梁基础承重的需要。设计可根据上层荷载选用桩径、桩长和最合适的持力层,和同等预制桩相比可节约钢材50％左右。施工的噪声和振动相对要小,无强烈振动和挤压,对周围建筑和地下管道破坏少。 由于施工管理不善,施工技术素质低,成孔和
Slurry wall cast-in-place bored piles are suitable for construction on land or in water areas. Holes can be formed in various soil layers below the groundwater level or above groundwater level. They can also have complex geological conditions, multiple layers, uneven weathering, and large variations in hardness and hardness. The rock formations are constructed and are not affected by the seasonal climate. The maximum vertical bearing capacity of a single pile can reach 1000kN, which can meet the needs of high, large, heavy-duty buildings and the foundation of heavy bridges. The design can select pile diameter, pile length and the most suitable bearing layer according to the upper load, and can save about 50% of steel compared with the same precast pile. The construction noise and vibration are relatively small, without strong vibration and extrusion, and less damage to the surrounding buildings and underground pipelines. Due to poor construction management and low construction technical quality,
