Classification of steel sheet piles

Views:14    

In the soft soil or loose sand in the steel sheet piles when the pile is now, this problem is often in the root piling method appears, because the pile is being set to lock the friction resistance is greater than the former - the root has been playing in the set Of the pile may be adjacent to the pile with the sink to the design of the height of the pile into the friction.

Classification of steel sheet piles

   There may be one or more of the following circumstances may occur associated with the problem:

1) steel sheet pile forward;

2) the pile rotates to produce the lock friction;

3) piling vibration to sand into the lock;

4) Piling when the lock is not clean;

5) The lock is damaged or connected to the other.


   The method of correcting vibrating piling is to pull the sheet pile to the desired elevation and to solder together in pairs, and then it is usually easier to type in the soft soil. You can also use the impact hammer instead of vibration hammer, when encountered with local pile, the simplest precaution is to co-sink the pile to the temporary guide to the purlin, but the purlin need to have enough support to prevent the piling The process of moving or overturning. If the pile vertical and straightness is good, then the joint sinking rarely occurs, the use of locking sealant to reduce the access to the lock of the soil can also alleviate this situation.

 

   Pile wall length control When the use of locking plate is not crimping the pile, by adjusting the distance between the guide purlin and the appropriate rotation at the lock, you can adjust the length of the steel sheet pile wall length. As the rotation of the lock will affect the appearance of the wall, increase the pile resistance and tripping probability, so the permanent building is not recommended to use this method. When the sheet pile is crimped in pairs, the position and direction of the sheet pile have been fixed due to crimping, so that the length of the pile wall can not be adjusted in this way.


   If you have to achieve accurate theoretical wall length, you need to use the prefabricated pile 10134 Piling error Usually the location and direction of the piles have been marked in the construction drawings, but due to rolling error, soil conditions and piling processes and other reasons The layout of the theory is biased. Domestic Larsen steel sheet pile manufacturers which should be consistent with the following values of the top of the pile from the axis of deviation from the axis of 50mm static pressure pile Wang 75mm; pile height deviation 20mm.
