Production process of welded steel plate pile

Abstract

The invention discloses a production process of a welded steel plate pile. The production process of the welded steel plate pile comprises the following steps of a cross section parameter of a sectionof the welded steel plate pile are designed through theoretical calculation, and the designed section parameter is consistent with the requirements of customers; a cold bending steel plate pile is produced through a cold bending forming device; and a steel plate is selected, and the steel plate is cut into a plurality of steel plate strips. According to the production process of the welded steelplate pile, the cold bending steel plate pile and the steel plate strips are welded together to form a new welded steel plate pile, the advantages of the hot-rolled steel plate pile and the cold bending steel plate pile can be combined, the high-section parameters of the hot-rolled steel plate pile can be realized, and the convenient and economic performance of the cold bending steel plate pile profile can be realized, the steel consumption of the hot-rolled steel plate piles with the same cross-section parameters is reduced, and the production cost of products is reduced; the hot-rolled steelplate pile can be adapted to the market with a constantly changing environment, and the reaction speed of enterprises on the market is greatly improved; and the purpose that the steel amount per square meter of wall is reduced by 28.3% can be achieved, the production investment cost of users is greatly reduced, and great market popularization and application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of steel sheet pile production, in particular to a production process of welded steel sheet piles. Background technique [0002] The steel sheet pile is a product used by developed countries in the 1920s. It is a type of steel with a lock. Its cross-section has a straight plate shape, a groove shape, and a Z shape. There are Larson type, Lackawanna type, etc., and their advantages are: high strength, easy to penetrate into hard soil layer; can be constructed in deep water, if necessary, add diagonal supports to form a cage, good waterproof performance; can be composed according to needs Cofferdams of various shapes can be reused many times, and have a wide range of uses. The engineering examples prove that lattice steel sheet piles are promising in port hydraulic construction. Steel sheet piles are environmentally friendly, energy-saving, high-efficiency and reusable materials. For port terminals, independe...

Problems solved by technology

[0002] The steel sheet pile is a product used by developed countries in the 1920s. It is a type of steel with a lock. Its cross-section has a straight plate shape, a groove shape, and a Z shape. There are Larson type, Lackawanna type, etc., and their advantages are: high strength, easy to penetrate into hard soil layer; can be constructed in deep water, if necessary, add diagonal supports to form a cage, good waterproof performance; can be composed according to needs Cofferdams of various shapes can be reused many times, and have a wide range of uses. The engineering examples prove that lattice steel sheet piles are promising in port hydraulic construction. Steel sheet piles are environmentally friendly, energy-saving, high-efficiency and reusable materials. For port terminals, independent piers and approach dikes, breakwaters, and underground diaphragm walls, there are currently two main types of steel used in the market: one is hot-rolled steel sheet piles, and the other is cold-formed steel sheet piles. These two methods have their own advantages and disadvantages. , hot-rolled steel piles can produce steel sheet piles with the same cross-section and different thicknesses according to the requirements of cross-section parameters in cross-section design, but it is suitable for mass production. For small batches of steel sheet piles, the cost of molds is too high and the economy is too low. It cannot be produced and cannot adapt to the ever-changing needs of the market at that time. Although cold-formed steel sheet piles have great advantages in mold commonality and fast market response, if products with the same cross-sectional parameters as hot steel sheet piles are produced, The amount of steel used will increase a lot. In view of the above problems, the present invention is specially designed to solve it.
