Embodiment Construction
[0077] Such as Figure 1-2 As shown, the anti-leakage construction method of the anchor cable in the deep foundation pit support project includes the construction technology of the anti-leakage auxiliary pile of the anchor cable and the construction technology of the plugging of the end of the anchor cable lock;
[0078] Wherein, described anchor cable anti-seepage auxiliary pile construction technology comprises the following steps:
[0079] 1) Measuring and setting out
[0080] According to the pile position line determined by the plan, use small wooden piles or other obvious materials to measure and place specific pile points, and number them as the original data of construction records to locate and correct verticality:
[0081] 2) Pile driver in place and centered
[0082] When the drilling rig is placed and positioned, the machine base should be flat and the machine tower vertical before drilling. The vertical deviation of the mixing pile should not exceed 1.5%, and th...

The invention discloses an anchor cable anti-seepage construction method for deep foundation pit supporting engineering. The anchor cable anti-seepage construction method comprises an anchor cable anti-seepage auxiliary pile construction process and an anchor cable lock end leaking stoppage construction process. The anchor cable anti-seepage auxiliary pile construction process comprises the following steps of surveying and setting out, pile machine in-place centering and pre-stirring sinking. According to the anchor cable anti-seepage construction method, through a disclosed relevant settlement subsystem, the relation among the humidity of the corresponding settlement position, the working current of control equipment and the descending speed can be automatically collected, the time needed for reaching the target settlement speed under the condition that any factor is not changed is explored, then according to the explored data, the scheme that when the target settlement speed needs to be reached, the minimum energy consumption is achieved, meanwhile, the consumed time is relatively short, and the efficiency is the highest through combination of the minimum energy consumption and the short consumed time can be automatically calculated, the working efficiency is improved, and manual attempts are avoided.
Description
technical field [0001] The invention belongs to the field of deep foundation pit support and relates to an anti-leakage technology, in particular to an anchor cable anti-leakage construction method for deep foundation pit support engineering. Background technique [0002] The patent with the publication number CN107604907A discloses a construction method for anti-leakage construction of anchor cables in deep foundation pit support engineering, including the construction technology of anti-leakage auxiliary piles for anchor cables and the construction technology for plugging the ends of anchor cable locks. The plugging operation can be done once. Completed, high-pressure injection of oil-based polyurethane water-swellable water-stop material four-sided plugging operation is convenient and fast; it has high reliability, prevents slope leakage well, and at the same time ensures the safety of the slope; [0003] However, it aims at how to control the corresponding mixer for subs...
