Controllable pressure difference open caisson method in tailing warehouse
The invention discloses a controllable pressure difference open caisson method in a tailing warehouse. According to the controllable pressure difference open caisson method in the tailing warehouse, a radiation well shaft arranged in tailings is included, a pressurization platform is arranged at the inner bottom of the radiation well shaft in the tailings, an inner cylinder is connected to the pressurization platform, and the method further comprises the steps S1 to S6. According to the controllable pressure difference open caisson method in the tailing warehouse, the defects of a traditional open caisson method can be overcome, the situation that part of tailings are solidified into layers due to the fact that the tailings in the tailing warehouse are formed by long-term accumulation, open caisson is difficult to sink once the open caisson in the tailing warehouse encounters buoyancy and well periphery friction force, resistance brought by solidification is larger than the dead weight of a shaft, at the moment, we need to push the shaft to sink by external force; according to the controllable pressure difference open caisson method in the tailing warehouse, the water level can be adjusted according to the actual situation encountered by the open caisson, the shaft is pushed by the water pressure and the shaft self weight to accelerate sinking, and the sinking speed of the well can be controlled by adjusting the water level. The method is easy to apply, convenient to operate, low in cost and capable of accelerating the construction progress.
尾砂库内可控压差沉井法，包括设置在尾砂中的辐射井井筒，所述尾砂中辐射井井筒的内底部设置有加压平台，所述加压平台上连接有内筒，还包括步骤S1‑步骤S6。本发明采用尾砂库内可控压差沉井法，可克服传统沉井方法的不足，由于尾砂库的尾砂是靠长期堆积而成的，导致尾砂存在部分固结成层的情况，在尾砂库内沉井一旦遇到浮力和井周摩擦力、固结带来的阻力大于井筒自重，沉井下沉很困难，这时我们就要借助外力推动井筒下沉；尾砂库内可控压差沉井法就可根据沉井遇到的实际情况调整水位，靠水的压力和井筒自重推动井筒加快下沉，可通过调控水位控制井的下沉速度。此方法应用简单，操作方便，成本较低、可加快施工进度。
