摘要： A novel method of injecting a back filling injection material employed in a shield-forming process is described herein. A screw type injection pump with a hopper connected to its intake port is utilized. This pump is rotated in a reverse direction to intake a back filling material into said hopper through a delivery hose connected to its delivery port. The upper limit pressure and a lower limit pressure for the injection pump are set for injection of the back filling material. The injection pump is next rotated in its normal direction to inject the back filling material to a desired location through the delivery hose, and then, after completion of the injection filling of the back filling material, the injection pump is rotated in a reversed direction again to intake water through the delivery hose, thereby washing of the hose and the injection pump can be effected.

摘要： A method of injecting grout into soil using a combined injection and boring rod wherein the rod comprises a tip and at least one injection nozzle at the lowermost end thereof. A sleeve packer of an elastomeric material is embedded in a recess in the periphery of the rod along the length thereof. A plurality of passages extend in and along the rod, the passages being defined by at least two parallel inner tubes spaced within an outer tube, and further by the spacing between the outer tube and the inner tubes. The method includes the steps of inflating the sleeve packer by introducing fluid pressure into the recess through a hole in the outer tube communicating with one of the passages, feeding two liquids of curable grout through respective passages and mixing the two liquids within the rod at the tip of the rod, and then injecting the mixed grout into the soil from the injecting nozzle. Prior to inflating the sleeve packer, the rod is actuable for boring a hole in the soil to a predetermined depth using the boring tip on the rod. After the step of injecting the mixed grout, the packer is retracted into the recess and the rod can then be actuated to restart boring to a greater depth.
摘要翻译：一种使用组合的注射和镗杆将浆料注入土壤的方法，其中杆包括尖端和在其最下端的至少一个注射喷嘴。弹性材料的套筒封隔器沿其长度嵌入在杆的周边的凹部中。多个通道在杆内和沿着杆延伸，通道由在外管内间隔开的至少两个平行的内管以及外管和内管之间的间隔限定。该方法包括以下步骤：通过将外部管中的一个孔与其中一个通道相连通，将流体压力引入到凹槽中来充气套筒封隔器，通过相应的通道供给两个可固化浆液的液体，并将棒内的两种液体混合在然后从注射喷嘴将混合的灌浆液注入土壤中。在使套筒封隔器膨胀之前，杆可致动以使用杆上的钻尖将土壤中的孔镗孔至预定的深度。在注入混合砂浆的步骤之后，封隔器缩回到凹部中，然后可以致动该杆以重新开始钻孔到更大的深度。
