Waste pumping well grouting sealing and filling device
The invention relates to the field of waste well treatment devices. A waste pumping well grouting sealing and filling device comprises a grouting mechanism and further comprises a cutterhead mechanism used for cutting a well casing open, and the cutterhead mechanism is detachably installed at the bottom of the grouting mechanism. The grouting mechanism comprises a main supporting pipe and a grouting pipe, a closed grouting chamber is arranged at the bottom of the main supporting pipe, and a grout spraying opening is formed in the side wall of the grouting chamber; the grouting pipe is arranged in the main supporting pipe, the top of the grouting pipe extends out of the main supporting pipe, and the bottom of the grouting pipe extends into the grouting chamber; a blocking piece is fixed to the side wall of the main supporting pipe and located above the slurry spraying opening. The well pipe opening is cut open through the cutter head mechanism, cement paste is injected into the packing layers inside and outside the pumping well through the paste spraying opening, the packing layers are effectively filled with the cement paste to be hardened, and the situation that underground water pollution caused by the fact that the packing layers are not closed subsequently of the abandoned well is diffused through the packing layers in a serial mode is effectively avoided; and the waste pumping well string layer pollution risk is reduced.
本发明涉及废井处理装置领域。一种废弃抽水井注浆封填装置，包括注浆机构，还包括用于切开井管的刀盘机构，刀盘机构可拆卸安装在注浆机构的底部；注浆机构包括主支撑管以及注浆管，主支撑管的底部设有封闭的注浆室，注浆室的侧壁开设有喷浆口；注浆管设置在主支撑管内，且注浆管的顶部延伸出主支撑管，注浆管的底部伸入注浆室内；主支撑管的侧壁固定有挡片，挡片位于喷浆口的上方。本发明通过刀盘机构切开井管口，水泥浆通过喷浆口碰出注入抽水井的内部以及外部的填料层，有效的将填料层也用水泥浆填充硬化，有效的避免了废弃井后续因填料层未封闭而引起的地下水污染通过填料层串层扩散，降低了废弃抽水井串层污染风险。
