Problems solved by technology

This method has the advantages of high rigidity, simple construction, and space saving. However, it can be seen from the actual implementation that when the fertilizer groove of the foundation pit is backfilled, the slope protection pile loses its own role as a temporary support, but the buried steel bars Cages cannot be recycled for reuse, creating a huge waste of material

Embodiment Construction

[0033] like Figure 1 to Figure 3 As shown, the circumferential type steel structure slope protection pile member 10 of the present invention includes an inverted cone-shaped hollow steel pipe 11, which is thick at the top and thin at the bottom. , the steel pipe 11 is welded with a steel filler for enhancing the horizontal rigidity, the steel filler is used to enhance the horizontal rigidity of the steel pipe 11, and together with the steel pipe 11 bear the horizontal force of the soil behind the slope protection pile, the steel pipe The top of 11 is provided with at least one pair of through holes 14, and each pair of through holes 14 is used to penetrate a steel plate, and the outer wall of the steel pipe 11 is bound with a circle of steel mesh 13, and the steel mesh 13 is used to improve the steel pipe 11 and the pile hole 20. The friction between the inner concrete 30 is used to firmly fix the steel pipe 11 in the concrete 30 .

Abstract

The invention discloses a recycling type steel structure slope protection pile component, a simple and convenient installing method which can effectively protect the slope protection quality and a simple and convenient disassembling method which can effectively guarantee the slope protection pile component integrity and the recycling usability. The recycling type steel structure slope protection pile component comprises an inverted-cone-shaped hollow steel pipe with the gradually reduced diameter from top to bottom; steel filler which can enhance the horizontal stiffness is welded inside the steel pipe; the top of the steel pipe is provided with at least one pair of through holes; a surrounding of steel screen is bound to the external wall of the steel pipe. The recycling type steel structure slope protection pile component is firm and reliable, allows recycle and effectively reduces reinforcement and concrete waste in temporary support.

Description

technical field [0001] The invention relates to a revolving steel structure slope protection pile component and an installation method and a dismounting method for the slope protection pile component, belonging to the field of foundation pit support slope protection piles. Background technique [0002] Slope protection pile is a common support method in foundation pit engineering, and it is widely used in geotechnical engineering with the use of anchor rods, internal supports and other support forms. [0003] At present, slope protection piles generally adopt the method of pouring concrete with steel cages, specifically: after the pile holes are excavated, a steel cage is placed in the pile holes, and then concrete is poured. This method has the advantages of high rigidity, simple construction, and space saving. However, it can be seen from the actual implementation that when the fertilizer groove of the foundation pit is backfilled, the slope protection pile loses its own r...
