Hydraulic notching machine is a continuous hydraulic slotting machine, which adapts to the slotting for the straight line or a curvature with large radius corners; when the curve radius of curvature is small, the slope of saw body will often severely exceed the design or specification requirements in the slotting process, lowering groove sag and saw body will easily twist and damage. In view of this situation, you can adjust the wall axis of the original corners in the design of the wall axis range to two or even more than a straight line segment polyline, carry out slotting construction according to broken line; drill a hole at the fold point to connect. When slotting near the drilling, control the saw slotting slope, make sure the lower end of the saw body go into the hole, then hang out saw body to adjust the slotting direction and continue slotting, which can not only adapts to the performance of slotting machine, which also realizes continuous slotting.
Damage of groove wall collapse
Groove wall collapse. Groove wall collapse has a variety of reasons, and the situation of the collapse is also different. If the groove wall collapses, it will not only seriously bury the hydraulic notching machine saw body in the ground, delaying the progress of the project, which may make the machine dump due to the collapse of the ground surface. Therefore it should be highly valued. Except special foundations, we can think that if mud liquid level in the tank drops, then tank wall collapse is bound to happen, which even makes the slots comprehensively damaged. The majority of the tank level drops are caused by the leakage of plasma. If there are tainted slurry signs, you should immediately take measures, raise the saw body to the ground.
Prevent catheter being buried in concrete
Prevention of catheter blockage, prevent catheter being buried in concrete. Carefully check whether the catheter is bent, whether there is residual consolidation of concrete on the inner wall of the catheter before installing the catheter, if the catheter is bent, then it should be corrected or abandoned, clean the residual concrete. Also note that if the catheter insertion concrete depth is too large or if stop pouring concrete for too long on the midway, the catheter will not be able to pull out. To prevent the catheter being buried in the concrete, you should measure height of the concrete surface, determine the safety insertion depth of the catheter, and the interrupt time of pouring should be as short as possible, continuously pouring.
Hydraulic notching machine new technology has good prospects for development
Currently, the hydraulic notching machine continuous impervious wall new technology has been widely used in the section of reinforcement project in the lower reaches of the Yellow River, and has achieved good results in the promotion and application of the Songhua River and the Pearl River Basin. The hydraulic shearing machine technology is widely used in the reservoir dam foundation seepage, embankment foundation seepage control and reinforcement project. It can rapidly complete the seepage control and reinforcement of tasks at low-cost, which has good prospects for development.
