Side slope slippage treatment method based on pressure grouting
The invention belongs to the technical field of side slope treatment, and particularly relates to a side slope slippage treatment method based on pressure grouting, which comprises the steps of position determination, coaming pressing-in, exhaust pipe arrangement, exhaust extrusion and grouting consolidation. The surrounding plate is pressed into the periphery of the landslide, so that the movement of partial underground water can be isolated, and the aggravation of landslide sliding caused by the movement of the underground water can be prevented; then, a sealing film is arranged on the surrounding plate, meanwhile, air is extracted outwards through an air extraction pipe driven into the soil layer, so that a pressure difference is formed on the two sides of the sealing film, then the sealing film is subjected to pressure perpendicular to the landslide, the landslide can be prevented from continuously sliding downwards, and then grouting is conducted in the landslide by driving a grouting pipeline; due to the fact that the landslide body is in the stable state under the continuous air exhaust effect of the air exhaust pipe, the landslide can be kept in the stable state in the process of arranging the grouting pipe and grouting, and the construction safety can be improved.
本发明属于边坡治理技术领域，具体的说是一种基于压力注浆的边坡滑移治理方法，包括位置测定、围板压入、抽气管设置、抽气挤压和注浆固结；本发明中通过在滑坡的外围压入围板，进而能够起到隔绝部分的地下水的活动，进而能够防止因地下水的活动造成滑坡滑动的加剧；随后在围板上设置密封膜，同时通过打入土层内部的抽气管，向外部抽气，使密封膜的两侧形成压力差，进而使得密封膜受到垂直于滑坡的压力，进而能够防止滑坡继续向下滑动，随后在通过打设注浆管道，向滑坡内部注浆，由于滑坡体在抽气管的持续抽气作用下，使得滑坡体处于稳定的状态，进而使得在设置注浆管和注浆的过程中，滑坡都能够保持稳定的状态，能够增加施工的安全性。
