Problems solved by technology

The commonly used combined steel sheet pile in China is to assemble and weld four "Z" shaped steel sheet piles with locks to form a combined steel sheet pile with locks on the water-facing side and no locks on the soil-facing side. The structure and The production has the following disadvantages: ①. All four "Z" shaped steel sheet piles need to be imported, and the project cost is relatively high; ②. Part of the lock on the facing surface needs to be cut off, resulting in a serious waste of materials (about 15% of raw material loss); ③. There is a lock on the surface facing the water and the surface facing the soil, which is easy to seep water, which is not conducive to the structure's soil retaining and water stop

Embodiment Construction

[0012] See attached figure 1 , the steel sheet pile 1 of the present invention is an imported wide-width "U"-shaped steel plate. The back 11 and the flanges 12 on both sides form a raised portion. On both sides of the raised portion, there are arm portions parallel to the web portion. 13. Two lock openings 3 are respectively provided at the ends of the two arms, which are arranged approximately in point symmetry with each other, so that more than two wide "U"-shaped steel sheet piles 1 can be connected through the mutual engagement of the locking openings on both sides. , the raised back of the wide "U"-shaped steel sheet pile 1 is provided with a domestic "H"-shaped steel 2, and the flange of the "H"-shaped steel 2 and the raised back of the "U"-shaped steel sheet pile 1 are fixed by welding or bolts The combined steel sheet pile with locking openings 3 on both sides can be welded by discontinuous welding or continuous surfacing welding.

Abstract

The invention discloses a combined steel sheet pile for a bay dock or a dock, which is characterized in that the combined steel sheet pile is combined by a steel sheet pile and profile steel, two sides of the steel sheet pile are provided with wide U-shaped steel sheet piles with locking notches, and the profile steel is H-shaped; and the H-shaped profile steel is arranged on the convex back of the U-shaped steel sheet pile, and a flange of the H-shaped profile steel is fixedly connected with the U-shaped steel sheet pile by welding or through a bolt. The invention also discloses an integrative upright wall for the bay dock or the dock. Compared with the prior art, the combined steel sheet pile has various section moduli; and under the same section modulus, the utilization rate of the steel is higher, the home-made rate can reach about 60 percent, the using amount of the import steel sheet pile is greatly reduced, the construction cost is lowered, the manufacturing process is simple, the assembly speed is high, and the integral structural property is good.

Description

technical field [0001] The invention relates to the technical fields of port engineering and foundation engineering, in particular to a combined steel sheet pile and an integrated vertical wall used for a port wharf or a dock. Background technique [0002] As a traditional earth retaining structure, steel sheet piles have the advantages of high strength, light weight, fast construction, environmental protection, beautiful appearance, and recyclability. They are widely used in transportation, water conservancy, municipal and other industries. Commonly used steel sheet pile models include U-type, Z-type and so on. In the case of a certain material strength, with the increase of the retaining height, the single-piece steel sheet pile cannot meet the requirements of strength and deformation due to its small flexural modulus. Therefore, various types of combined steel sheet piles (such as BOX type, etc.) have appeared to increase the section modulus of steel sheet piles to provi...
