How to deal with common problems of highway pile drivers: Highway pile driver operators must learn some basic operating principles and familiarize themselves with the causes of faults to work more efficiently. In the course of use, we won't encounter problems every year. Now, Shandong Hengwang Machinery Co., Ltd. will take you to understand the common problems during use? How to solve them during the construction of guardrails. 1. Accurately master the data of various facilities, especially the exact location of various pipelines buried within the subgrade. Underground facilities must not be damaged during construction. If the underground communication pipelines, drainage pipelines, or the top of the culvert are not buried deep enough, the position of the column should be adjusted, or change the fixing method of the column when problems arise. 2. There can be an accurate way to operate the machine, and maintain the machine in time, which can also prevent the occurrence of the machine. If there is a problem with the machine, it should be handled calmly. Do not blindly seek repairs. Otherwise, the problem cannot be solved, but the machinery cannot operate normally, leading to 3. Project delays when the column is driven too deep, it is not allowed to pull out the column for correction. The rest should be pulled out, and the foundation should be compacted again before driving, or the position of the column should be adjusted to 4. The bridge guardrail should be installed with a flange plate. Pay attention to the positioning of the flange plate and the elevation of the column top during operation 5. Control of the pile driver may also encounter the phenomenon of pile body slapping and pile hammer rebound. The reason is that when the pile end encounters obstacles or hard soil layers, the pile body bends too long, and the drop hammer is too high.
In this case, the cause should be checked first, and measures should be taken to make the pile pass through or avoid the obstacle. If the pile does not penetrate the soil, avoid or hit heavily; use a heavy hammer pile driver to strike and change the drop hammer height. Troubleshooting steps 1. The oil pump does not turn: the reason is that the oil pump engagement device is not connected, and the exclusion method: step on the clutch, put on the oil pump coupling device 2. The multi-way valve does not return to the middle position: the reason is that the return spring is damaged, and the exclusion method is to replace the return spring 3. Multi-way valve operation is laborious: the reason is that iron filings or dirt enter the valve stem, and the exclusion method is to clean up iron filings or dirt.
