Embodiment 1

[0061] A composite material sheet pile, comprising a pile body 1, the cross-sectional shape of the pile body 1 is as follows Picture 1-1 As shown, the splicing structure of the pile body 1 and the pile body 1 is as follows Figure 1-2 As shown, the three-dimensional structure of the spliced ​​piles is as follows Figure 1-3 shown. The pile body 1 is a composite material pile body, the upper end of the pile body 1 is wrapped with a stainless steel sleeve 2, the lower end is connected with a stainless steel pile shoe 3, and the two sides of the pile body 1 are respectively connected with adjacent piles. Lock 4 connected to body 1, such as Figure 1-3 As shown; the pile body 1 is composed of a core material 101, an inner wrapping layer 102 wrapping the core material 101 and an outer wrapping layer 103 wrapping each core material 101 wrapped with the inner wrapping layer 102 into a desired shape, adjacent A lattice structure 104 is formed between the core materials 101, such as...

Embodiment 2

[0075] Such as diagram 2-1 , 2-2 , as shown in 2-3.

[0076] The difference between this embodiment and the first embodiment is that the cross-sectional shape of the sheet pile is oblique Z-shaped, and the rest is the same as the first embodiment.

Embodiment 3

[0078] Such as Figure 3-1 , 3-2 , 3-3 shown.

[0079] The difference between this embodiment and the first embodiment is that the cross-sectional shape of the sheet pile is oblique U-shaped, and the rest is the same as the first embodiment.

Abstract

The invention discloses a composite material sheet pile and a preparation method thereof. The composite material sheet pile comprises a pile body (1) and is characterized in that the pile body (1) is the composite material pile body; the upper end of the pile body (1) is covered with a stainless steel jacket head (2), and the lower end of the pile body (1) is connected with a stainless steel pile shoe (3); two side edges of the pile body (1) are respectively connected with a lock catch structure (4) connected with the adjacent pile body (1); the pile body (1) is composed of a core material (101), an inner covering layer (102) and an outer covering layer (103), wherein the inner covering layer (102) covers the inner core (101), and the outer covering layer (103) covers each core material (101) covered with the inner covering layer (102) into the required shape; and a lattice structure (104) is formed between adjacent core materials (101). The composite material sheet pile is characterized by replacing steel with plastics, and has the advantages of light weight, high intensity and long service life and can be reused.

Description

technical field [0001] The invention relates to an engineering construction tool, in particular to a composite material sheet pile made of composite material for replacing the existing steel sheet pile, in particular to a composite material sheet pile and a preparation method thereof. Background technique [0002] As we all know, the cofferdams made of traditional materials in our country use wooden sheet pile cofferdams, wooden cage cofferdams, steel sheet pile cofferdams, concrete cofferdams, etc. The cofferdams made of these traditional materials have made great contributions to the construction of our country. Among them, the steel sheet pile cofferdam is the most widely used in civil engineering structures. Although steel has the characteristics of high strength and high elastic modulus, it is easy to rust in the atmospheric environment, especially in the marine corrosive environment. If it is not protected against corrosion, the service life very short. Moreover, for ...
