What are the key points and measures for leak and seepage prevention of steel sheet piles?

Nowadays, the most commonly used building material in the construction industry is steel, and steel sheet piles are one of the more frequently used steel products. There are many points to note during the use of steel sheet piles. Today, let's learn about the key points and measures for leak and seepage prevention of steel sheet piles.

1. During the entire process of driving steel sheet piles, positioning and guiding must be well done, and the verticality in both directions must be strictly controlled to ensure good interlocking between piles, ensuring that the steel sheet pile wall is vertical and closely fits around the guide frame. This is the key to water stopping and seepage prevention;

2. When water leakage occurs due to unsealed interlocks during foundation pit pumping, use fiber-rich cotton wool to plug the gaps;

3. For wider pile gaps, hemp fibers mixed with butter can be used to plug and stop water. A comprehensive treatment method can also be adopted by spreading fly ash, sawdust, or shrinkage cement along the water flow direction on the pile surface outside the cofferdam to achieve the purpose of water stopping. It is also possible to embed battens, cotton wool, hemp velvet, etc. on the inner side of the sheet piles after the leakage location is found during pumping, or to throw coal ash mixed with sawdust into the water outside the leaking gaps. In our previous work, we sometimes directly plugged the gaps with sawdust.

What issues should be noted when removing steel sheet piles?

We have discussed the functions of steel sheet piles before. It is precisely because of these functions that steel sheet piles are unanimously welcomed by builders. The market for steel sheet piles in daily life is also relatively broad. Today we will mainly learn about the issues that should be noted when removing steel sheet piles.

　　1. The installation and removal of the pile driver and auxiliary arm should be carried out on flat and hard ground.

　　2. When two or more people or a guide operator work together, please operate according to the specified communication signals.

　　3. When loading and unloading the pile driver, please use a crane. The hook must have a device to prevent it from unhooking.

　　4. Please check daily whether the motor brake, hydraulic pipes, and bolts, nuts, shaft pins, etc. of each part are loose. Check the oil (lubricating oil) capacity and leakage of the pile driver.

　　5. The installation and removal of the auxiliary arm should be carried out according to the essentials for installing and removing the bucket of a hydraulic excavator.

　　6. Please check whether the clamping jaw teeth are excessively worn.

　　7. Please regularly remove accumulated soil and other debris from the pile head. If the pile head is deformed, do not remove it.

　　8. When loading and unloading hydraulic pipes and connectors, please note to turn off the engine of the hydraulic excavator and proceed after the internal pressure of the hydraulic system is released. If internal pressure remains, oil will spray. Regarding the release of internal pressure
