Well casing centering construction method for underground water monitoring well
The invention relates to a well casing centering construction method for an underground water monitoring well. The well casing centering construction method comprises the following steps that constructing is carried out by adopting centering devices, a well casing of the underground water monitoring well is centered by utilizing flexible sizes of the centering devices, the size is adjusted by virtue of a buckle type expansion joint, inner circular rings of the multiple centering devices sequentially sleeve the well casing at intervals, the length of the inner buckle type telescopic joint of the inner circular rings is adjusted so that the inner circular rings can be fixed to the well casing, the well casing provided with the centering devices is placed in a hollow drill rod hole, and after the well casing is well placed, a gap between the outer wall of the well casing and the inner wall of the hollow drill rod hole is filled with filler according to design requirements. According to the well casing centering construction method for the underground water monitoring well, it can be guaranteed that the well casing is located in the center of the drill hole, normal construction of the filler is not affected, it is guaranteed that the space around the well casing is consistent in size, and then it is guaranteed that the filler is evenly filled in the horizontal direction.
本发明涉及一种地下水监测井的井管定中施工方法，通过采用定中器进行施工，利用定中器灵活的尺寸定中地下水监测井井管，通过卡扣式伸缩节实现调节尺寸，依次将若干定中器的内圆环间隔套在所述井管上，调节所述内圆环的内卡扣式伸缩节长度尺寸使所述内圆环固定在井管上，将装有定中器的井管放入所述中空钻杆孔内，放好井管后，在所述井管外壁与所述中空钻杆孔内壁之间的间隙内按照设计要求进行填料填充。本发明的施工方法能够确保井管在钻孔中的中心位置，不但不影响填料正常施工，而且确保井管周边的空间大小相一致，进而确保填料厚度在水平方向上均匀填充。
