Dewatering well construction device and construction method thereof
The invention discloses a dewatering well construction device and a construction method thereof. The device comprises a movable drilling platform, wherein a moving mechanism is arranged at the bottomof the movable drilling platform, hydraulic supports are arranged on the periphery of the movable drilling platform, a leveling limiting frame is arranged on the front portion of the movable drillingplatform, a winch is arranged on the rear portion of the movable drilling platform, the leveling limiting frame comprises vertical supports located on the two sides, a cross beam located on the top and a workbench located at the bottom, the vertical supports are connected with an inclined strut hydraulic rod and a horizontal hydraulic rod on the movable drilling platform, a steel rope on the winchbypasses the cross beam and then is downwards provided with a lifting hook, a mud pump of a drilling machine can be hung on the lifting hook, a through hole is formed in the position, below the lifting hook, on the workbench, a pair of oppositely-opened baffles are installed on the through hole, when the two baffles are opened, a downcomer of the drilling machine can penetrate through the throughhole, when the two baffles are closed and fixed, a limiting hole is defined by edge notches of the two baffles, and the inner diameter of the limiting hole is slightly larger than the working outer diameter of the downcomer and smaller than the outer diameter of a downcomer connector. The device is convenient to transfer, stable in well drilling, low in site flatness requirement, capable of shortening the construction period and high in hole forming quality.
本发明公开了一种降水井施工装置及其施工方法，该装置包括移动钻井平台，移动钻井平台的底部设有移动机构、四周设有液压支撑、前部设有调平限位架、后部设有卷扬机，调平限位架包括位于两侧的竖向支撑、位于项部的横梁和位于底部的工作台，竖向支撑与移动钻井平台上的斜撑液压杆和水平液压杆连接，卷扬机上的钢绳绕过横梁后向下且设有吊钩，钻机的泥浆泵能吊在吊钩上，工作台上吊钩下方设有通过孔，通过孔上装有一对对开的挡板，两个挡板打开时钻机的降水管能穿过通过孔、关闭且固定时两者的边缘缺口围成限位孔，限位孔内径略大于降水管工作外径、小于降水管接头外径。本发明转场方便，钻井稳定，对场地平整度要求不高，节省工期，成孔质量高。
