Information

  In the inspection of the sonic jet method, the deformation, blockage and deflection of the grouting steel pipe manufacturer are often encountered. Hollow grouting bolts should be connected with the analysis and determination that affect the inspection results. Can not even give the integrity of the pile. The main reasons are as follows:

  ( 1) The sealing ring is broken and twisted, and the joint of the grouting steel pipe manufacturer is not tightly sealed. When welding the joint of the grouting steel pipe manufacturer, the joint is welded through the main body, and the bone mouth or the bottom of the pipe is not tightly sealed. During the construction process, a mud strategy will be formed, and even cement slurry will block the pipeline.

  ( 2) The hollow grouting anchor pipe body deforms when a wild basin is formed during transportation .

  ( 3) The grouting steel pipe manufacturer twists the horny rib cage into an electromagnetic mask during the sound side caulking device, free rib lifting or even delay, which causes the sound side liver. Point or bind tightly, and the binding distance is too large.

  ( 4) The joints of the grouted steel pipe manufacturer are misaligned and deformed due to the extrusion and left-right swing stroke of the grouted steel pipe during the process of pouring concrete. The reason for this phenomenon is that the rigidity of the steel pipe is not good enough, the point bonding or bonding is not strong, the bonding distance is too large, and the structure is too rough.

  ( 5) The diameter of the steel cage is changed, and some grouted steel pipe manufacturers adopt reinforcement methods when they get out of the steel cage.

  ( 6) There is no universal length for the key cage. Some grouted steel pipe manufacturers do not use reinforcement methods when they extend beyond the bottom of the steel cage.

  ( 7) The grouted steel pipe manufacturer is not good at punching and forming holes. When the tie rod cage is difficult to sink, it uses unconventional methods, such as strong pressure to deform the grouted steel pipe manufacturer to block the pipeline.

  ( 8) When the pile driver head is damaged, the hollow grouting anchor pipe is blocked due to the worker's non-injection and falling into the concrete block or debris .

  ( 9) Due to problems in planning and construction, the triangle or quadrilateral used to fix the grouting steel pipe manufacturer on the transverse surface of the steel cage is not a flat and parallel equilateral triangle or square, resulting in the grouting fixed on its corresponding The steel pipe manufacturer is not parallel in the mesh joint cage.

  ( 10) Misalignment of the sound tube during hoisting and fixing the steel cage. As a result, deformation occurred when connecting the grouted steel pipe manufacturer.

  ( 11) The sound of drilling. The influence of side pressure on the inside of the steel cage is reduced, and the grouting steel pipe manufacturer on the side moves or bends inward. Parallel connection is lost.
