Example Embodiment

[0105] Example: The application of the present invention includes a pile wall composed of sheet piles, a pile wall composed of two or more sheet piles (closable); including a pile wall composed of tube piles and sheet piles, two or more tubes Pile walls composed of piles and sheet piles also include pile walls composed of tube piles, and pile walls composed of two or more tube piles.

[0106] The diameter of the steel tube pile (including the width of the rectangular tube steel pile unit) of the tube pile is about 50cm. It is better that the distance between the edges of adjacent steel tube piles is 20-30cm. This distance is the narrowest part of the connecting pile . Used for Figure 24-27 Although the rectangular foundation pits are the most commonly used, the enclosure of the polygonal or irregular shape foundation pits can be formed by connecting the unit steel cylinder piles and the connecting piles of the present invention.

[0107] When the foundation pit is deep (5-10 met...

Abstract

The invention discloses a steel cylinder pile or steel sheet pile with sealing grooves and occlusion structures. The steel cylinder pile or steel sheet pile is provided with the waterproof sealing grooves; at least one groove used for sealing is formed in the connecting positions of steel sheet piles or steel cylinder piles; the cross section of each groove is convex-arc-shaped, concave or polygonal; pipes with the same sectional area are inlaid in the grooves; the steel sheet piles or the steel cylinder piles and the pipes inside the grooves are rammed into a stratum together or separately; and after the steel pipes are pulled out, waterproof sealing materials are reserved in or injected into cavities inside the grooves so as to form waterproof sealing layers at the connecting positions of the steel sheet piles or the steel cylinder piles. The steel cylinder pile or steel sheet pile has the advantages that in the application of a steel structure continuous wall, a foundation and a foundation pit, particularly, the sealing structural steel cylinder pile is a rectangular steel cylinder pile, and rectangular steel cylinders are tightly arranged.

Description

technical field [0001] The invention relates to the construction of foundation pits and open cut foundations in the technical field of construction engineering, steel cylinders or steel sheet pile steel structure continuous walls with waterproof sealing grooves and occlusal structures to form a steel structure continuous wall system, and specifically relates to a continuous wall system for a certain A steel cylinder or steel sheet pile and steel structure diaphragm wall and application of a sealed occlusal structure applied under the condition of water-bearing stratum, especially the application of foundation pit reinforcement enclosure. Background technique [0002] Steel sheet piles are the most commonly used sheet pile cofferdams. Steel sheet pile is a kind of section steel with lock. Its section has straight plate shape, groove shape and Z shape, etc., and there are various sizes and interlocking forms. The common ones are Larson type, Lackawanna type and so on. It has...
