Core-pulling type electric charge anti-silt drainage soft soil foundation reinforcing device
The invention discloses a core-pulling type charge silt-preventing drainage soft soil foundation reinforcing device which comprises a hollow drill rod, a drainage sleeve, a gradient silt-preventing permeable structure and a sealing cap. The drainage sleeve is arranged in the hollow drill rod in a sleeved mode, the gradient silt blocking and water permeating structure is arranged at the bottom of the drainage sleeve, and the sealing cap is arranged at the top of the drainage sleeve in a sealed mode. The gradient silt-blocking water-permeable structure is sequentially provided with a water-permeable base material, an isolating layer, a sealing layer and a polyelectrolyte layer from outside to inside. A negative charge material is introduced into the soft soil foundation reinforcing device, and it is guaranteed that the drainage sleeve is prevented from being blocked by charged clay particles in the soft soil foundation drainage process. Meanwhile, the core-pulling type permeable base material and the isolating layer are adopted, so that residual uncharged impurities can be isolated from a small amount of clay particles with tiny charges, gradient isolation of the clay particles is achieved, the drainage device has repairability, long-term use of the device is guaranteed, and smooth drainage is guaranteed.
本发明公开了一种可抽芯式电荷防淤排水加固软土地基装置，包括中空钻杆、排水套管、梯度阻淤透水结构和密封帽；所述排水套管套设在所述中空钻杆内，所述梯度阻淤透水结构设置在排水套管的底部，所述密封帽密封设置于排水套管的顶部；所述梯度阻淤透水结构由外向内依次设置有透水基材、隔离层、封闭层和聚电解质层。本发明在软土地基加固装置中引进负电荷材料，保障排水套管在软土地基排水过程中避免带电黏土颗粒淤堵。同时采用可抽芯式透水基材和隔离层，不仅可将剩余不带电杂质与少量、微小电荷黏土颗粒阻隔，实现将黏土颗粒梯度阻隔，并且使得排水装置具有可修复性，保证装置长期使用，确保排水通畅。
