Problems solved by technology

Among the more mature retaining pile walls in the current foundation pit retaining piles, there are SMW piles and U-shaped steel sheet piles. Among them, the SMW piles play the role of water stop through the cement soil after mixing, and are the water barrier walls of the foundation pit. The construction process needs to consume a lot of cement, and the cement will generate a lot of dust, waste mud and replacement soil during the transportation and mixing process, causing environmental pollution; while the U-shaped steel sheet pile has a good water-stopping effect, but its bending resistance is weak , cannot reliably support the lateral earth pressure of the foundation pit

specific Embodiment 1

[0037] Specific embodiment one: as figure 1 , figure 2 As shown, an assembled composite enclosure pile in which I-shaped steel and U-shaped steel sheet piles are engaged, includes a supporting main pile 1 and a water-stopping auxiliary pile 2 .

[0038] The supporting main pile is used to bear the lateral earth pressure of the foundation pit. The supporting main pile includes several vertical supporting piles 1.1 arranged side by side. In this embodiment, the vertical support piles are I-beams. The vertical support piles are pressed into the soil layer of the foundation pit by static pressure.

[0039] The auxiliary water-stop piles include several U-shaped steel sheet piles 2.1 that are interlocked and connected. Waterstop auxiliary piles are used to prevent groundwater from entering the foundation pit. The U-shaped steel sheet pile is pressed into the soil layer of the foundation pit by static pressure.

Abstract

The invention discloses an I-shaped steel and U-shaped steel plate pile engaged fabricated composite fender pile. The I-shaped steel and U-shaped steel plate pile engaged fabricated composite fender pile is high in resistance to bending, can reliably support the lateral soil pressure of a foundation pit, can have the good water stopping ability without using cement and is conducive to environmental protection. The I-shaped steel and U-shaped steel plate pile engaged fabricated composite fender pile comprises a supporting main pile and a water stopping auxiliary pile, wherein the supporting main pile is used for bearing the lateral soil pressure of the foundation pit and comprises a plurality of vertical supporting piles arranged side by side; and the water stopping auxiliary pile comprisesa plurality of U-shaped steel plate piles which are connected in a mutually engaged mode, the water stopping auxiliary pile is used for blocking underground water to enter the foundation pit, and part of the U-shaped steel plate piles are connected with the vertical supporting piles.

Description

technical field [0001] The invention relates to an enclosure pile, in particular to an assembled composite enclosure pile in which I-shaped steel and U-shaped steel sheet piles are engaged. Background technique [0002] In the foundation pit construction of buildings or structures, the foundation pit enclosure piles are generally constructed first, and then the foundation pit is excavated. Among the more mature retaining pile walls in the current foundation pit retaining piles, there are SMW piles and U-shaped steel sheet piles. Among them, the SMW piles play the role of water stop through the cement soil after mixing, and are the water barrier walls of the foundation pit. The construction process needs to consume a lot of cement, and the cement will generate a lot of dust, waste mud and replacement soil during the transportation and mixing process, causing environmental pollution; while the U-shaped steel sheet pile has a good water-stopping effect, but its bending resistan...
