Description

Technical Field

[0002] U-shaped sheet piles (also called "J"-shaped sheet piles) are increasingly widely used because of their good mechanical properties and the advantages of being easy to manufacture. They are particularly suitable for use in the enclosure of various types of buildings during construction, such as large underground buildings, slopes, tunnels, port and wharf walls, and river bank renovation. During the production process of U-shaped sheet piles, production molds are needed for casting and molding. However, the existing U-shaped sheet pile production mold structure is relatively complex, and the side support covers the entire side of the mold. When the mold is opened, the entire support needs to be opened. The mold cost remains high, and the force required to open and close the mold is large, which wastes a lot of resources. At the same time, the bubbles in the U-shaped sheet pile molding process are not easy to dissipate, resulting in a lower density of the U-shaped sheet pile, which affects the structural strength and the service life of the U-shaped sheet pile. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to improve the prior art. Utility Model Content
