P1 (A): DH Quick Concrete Pile
    DH Quick Concrete Pile (DH advanced quick prestressed concrete pile) is the newly prestressed concrete pile developed by Dehan in the 2010s. It belongs to the first stage pile technology (P-LV1) of Dehan, combined with a variety of its own unique technology. Internal product code is type P1, or P1A.
    This product is mainly modified from "implantable prestressed concrete pile", in addition to the original advantages of implantable piles, but also has:

High-intensity construction period compression and integration of other types of capacity, pile head pull stronger and more stable, more stable durability, better quality control and so on.
 

     P1B: DH Quick Concrete Pile (Compacted type), is a pre-engineered, pre-stressed concrete pile modified by the Dehan Company from the P1A Quick Pile. It belongs to the first stage pile technology of Dehan (P-LV1B), combined with a variety of its own unique technology. Internal product code is type P1B.

    The main improvement of this product from "P1: DH Quick Concrete Pile", except the horizontal reforcement in the pile head. And also has the advantage:

High-intensity construction period compression and the ability to integrate other types of workmanship, quality control better.

    The DH-PHC prestressed pile technology overcomes the most vulnerable prestressed pile joints and pile head nodes, the prestressed pile technology at least 50 years ahead, far ahead of the world's prestressed pile technology. After overcoming the weaknesses of the pipe piles, DH-PHC fully exerts the material properties of prestressed concrete to the fullest, and further uses the pre-stressed piles in more engineering fields. The pre-stressed piles industry will immediately see Larger market, and expansion of business opportunities.

    Prestressed concrete piles (PC/PHC piles) is with a very high C/P value, widely used in engineering market. It has the advantages of low cost, easy construction, good quality control, good durability, but still has 3- disadvantages at upper, middle and lower end of pile. The upper-end disadvantage (pile-cap treatment) has been resolved by P1: DH quick concrete pile technology. The mid-end disadvantage (pile-connection) resolved by P2: DH pile-connection technology. So that the prestressed pile bearing capacity, to be fully transferred from the upper-pile to the lower-pile.
