Before staring an excavation operation, it is vital to have an in-depth understanding of the specific conditions and requirements of the construction. For an experience driver, it may only take a glance to roughly determine the construction conditons and have a good idea of what to expect. Similarly, on the task of digging a trench, full communication with the builder is indispensable. Clarifying the direction, starting and ending points, turning locations, width,depth and other details of the trench is a prerequiste to ensure smooth construciotn.
1. Establishing a frame of reference
Before digging a trench, the construction crew usually marks the outline of the trench by spreading lime lines, which becomes an important reference for the driver. When digging a straight trench, the driver should follow the trajectory of the lime line and try to maintain the consistency and coherence of the digging action to improve the working efficiency and construction quality. At the same time, the driver should periodically stop or get off the vehicle to check whether the trench deviates from the intended direction and make timely adjustments to avoid reworking. However, if the lime line is covered with dirt and difficult to read, the driver should look for other reliable reference,such as curbs, building foundations, or the edge of the excavator’s track plate, to ensure that the excavation is straight.
2. Addressing the chanllenge of digging a straight trench without a reference point
In the absence of an obvious reference, drivers need to use experience and skill to ensure that the trench is straight. They can use edge of the excavator’s track plate as a temporary reference and keep the trench straight by constantly adjusting the excavator’s position and travel direction. The key to this method is the driver’s keen observation and timely adjustment.
3. Techniques for realizing curved excavations
When digging a curved road with a certain curvature, the operator needs to utilize the bucket teeth or side teeth of the bucket to operate, and achieve the desired shape of the curved road through continuous adjustment and carving. This requires a high level of skill and patience.
4. The secret to leveling the bottom of the trench
To ensure that the bottom of the trench is level, the operator can use a measuring tool to control it precisely under the guidance of the construction crew. At the same time, using the bucket’s leveling function to trim the bottom of the trench is also a common method. The levelness of the trench bottom is critical, especially for treches where pipes are to be installed.
5. Strategies for improving trenching efficiency
The key to improve the efficiency of threnching operation lies in rational planning and fine operation. Firstly, the driver should ensure the stability of the excavator to reduce the operation difficulty and safety risk. Secondly, the slope and depth of the trench should be constantly confirmed during the digging process to avoid reworking. In addition, timely clearing of earth on both sides of the trench to prevent collapse is also an important measure to improve efficiency. This should be emphasized especially when working in wet or waterlogged environments. At the same time, the excavated trench is regarded as its own ‘work’ to carefully care for and protect is also the key to improve the efficiency and quality of work.
