SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a prestressing force U type sheet pile, it has saves construction period and construction equipment, improves the advantage of aesthetic property simultaneously.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a prestressing force U type sheet pile, its includes the U type sheet pile who adopts U type cross section pattern structural design, its characterized in that: the integrated into one piece is provided with the dovetail piece on the end wall of U type sheet pile, the length direction of dovetail piece is followed the length direction of U type sheet pile sets up, the dovetail of keeping away from the dovetail piece of U type sheet pile is seted up with dovetail piece mutual adaptation.

Through adopting above-mentioned technical scheme, at the in-process of pile, the forked tail piece through adjacent U type sheet pile mutually supports with the dovetail, realizes the quick concatenation construction between two consecutive U type sheet piles, makes to connect into a whole between a plurality of U type sheet pile, has saved construction period and construction equipment to better pleasing to the eye effect has.

Further, the length of the narrow flange of the dovetail block is 40mm-50 mm.

Through adopting above-mentioned technical scheme, difficult fracture damage that takes place between forked tail piece and the U-shaped sheet pile has improved the stability of whole sheet pile.

Further, a concrete layer is poured at the joint of the two adjacent U-shaped sheet piles.

Through adopting above-mentioned technical scheme, concrete layer carries out further reinforcement to the hookup location between two adjacent U type sheet piles, has further improved stability and leakproofness between two adjacent U type sheet piles.

Furthermore, the top angles of the sections of the U-shaped sheet piles are all arc angles.

Through adopting above-mentioned technical scheme, at the in-process of pile, reduced the stress that U shaped sheet pile stake angle department received, pile body quality is more reliable, and U shaped sheet pile has better resistance horizontal load ability.

Further, the top wall of the dovetail block is provided with a guide surface.

By adopting the technical scheme, the dovetail block can be conveniently inserted into the dovetail groove.

Furthermore, the side wall of the U-shaped sheet pile and the bottom of the U-shaped sheet pile are provided with conical surfaces inclined towards the direction of the U-shaped sheet pile.

Through adopting above-mentioned technical scheme, when piling to U shaped sheet pile, be convenient for U shaped sheet pile inserts and establishes to earth in.

Further, the upper surfaces of the U-shaped sheet piles are flush with each other.

By adopting the technical scheme, the integral attractiveness of the sheet pile is ensured.

To sum up, the utility model discloses following beneficial effect has:

1. in the piling process, the dovetail blocks and the dovetail grooves of the adjacent U-shaped sheet piles are matched with each other, so that the quick splicing construction between the two connected U-shaped sheet piles is realized, a plurality of U-shaped sheet piles are connected into a whole, the construction period and the construction equipment are saved, and the attractive effect is better;

2. the connecting position between two adjacent U-shaped sheet piles is further reinforced through a concrete layer, so that the stability and the sealing property between two adjacent U-shaped sheet piles are further improved;

3. the top corners of the cross sections of the U-shaped sheet piles are all provided with arc corners, so that the stress on the corners of the U-shaped sheet piles is reduced in the piling process, the pile body quality is more reliable, and the U-shaped sheet piles have better horizontal load resistance.
