Description

Point type guiding concrete sheet pile and protective wall

Technical Field

The utility model belongs to the technical field of pile foundation engineering of various building structure systems, in particular to a point-type guide concrete slab pile, and also relates to a protective wall formed by splicing the pile.

The mode of the present preferred as a bank protection wall adopts U-shaped plate pile splicing, T-shaped pile splicing or H-shaped support pile splicing, two adjacent piles are sequentially connected with each other through a rib groove insertion structure to form the bank protection wall, for example, a Chinese patent 'H-shaped support pile connection structure' with the patent number of ZL201320461012.5 (bulletin number of CN 203559411U) discloses a bank protection wall, a plurality of H-shaped support piles are sequentially spliced together without gaps through a splicing structure, the H-shaped prestressed concrete pile comprises two flanges and a web plate for connecting the two flanges, the cross section of the H-shaped prestressed concrete pile is H-shaped formed by the two flanges and the web plate for connecting the two flanges, and the two flanges and the web plate form grooves extending along the length direction of a pile body at two sides of the H-shaped prestressed concrete pile; but the combination between piles is formed by a rib-groove matching structure between flanges.

The width of the flange is narrow, so that the transverse sizes of the ribs and the slots on the flange are smaller, the requirement on the accuracy of the die is high, and the ribs and the slots are easy to damage in the demolding process. Moreover, when piling, the convex ribs and the slots with small cross sections are very difficult to match, in practice, the convex ribs and the slots are often not very matched together, so that the tightness of splicing between piles is poor, and the convex ribs and the slots are very high in production precision requirement and construction requirement of the piles. Because the cross section of the I-shaped pile (also called as H-shaped pile) is larger than that of the U-shaped sheet pile and the T-shaped pile, the resistance of the H-shaped pile is large when piling is not beneficial to piling although various mechanical properties of the pile are improved.

In view of the above, the existing i-piles (also called H-piles) need further improvement.
