Enclosure method for inserting H-shaped reinforced concrete slab piles in three-axis (two-axis) cement mixing pile

Abstract

The invention discloses an enclosure method for inserting H-shaped reinforced concrete slab piles in a three-axis (two-axis) cement mixing pile. The method comprises the following three processes of: making the H-shaped reinforced concrete slab piles; digging to obtain the three-axis (two-axis) cement mixing pile; and inserting the H-shaped reinforced concrete slab piles into the three-axis (two-axis) cement mixing pile, wherein multiple reinforcing steel bars are arranged in each H-shaped reinforced concrete slab pile; a plurality of embedded iron are arranged around one end of each H-shaped reinforced concrete slab pile; the three-axis (two-axis) cement mixing pile is formed through digging; multiple sections of the H-shaped reinforced concrete slab piles are welded with each other through welding the embedded iron and lifted by using a crawler crane; the welded H-shaped reinforced concrete slab piles are inserted into the three-axis (two-axis) cement mixing pile; the equipment is moved to a second position, to be dug, of the second three-axis (two-axis) cement mixing pile so as to carry out the same operations; and after a plurality of movements, the enclosure method for inserting the H-shaped reinforced concrete slab piles in the three-axis (two-axis) cement mixing pile can be completed. The enclosure method for inserting the H-shaped reinforced concrete slab piles in the three-axis (two-axis) cement mixing pile, disclosed by the invention, has the advantages of good bending resistance, low cost, high benefit, no noise, no pollution, environment friendliness and the like.

Description

technical field [0001] The invention relates to an enclosure method for inserting H-shaped reinforced concrete sheet piles into three-axis (two-axis) cement-soil mixing piles, which is mainly used in the construction of civil and industrial infrastructures, and is mainly used to build an enclosure fence around the foundation pit to facilitate underground excavation. The space is under normal construction, it prevents groundwater from flowing into the foundation pit, blocks the extrusion of the outer soil, and keeps the surrounding buildings, roads, and pipelines safe. Background technique [0002] The existing deep foundation pit enclosure methods include: ①Using three-axis (two-axis) cement-soil mixing piles to insert H-shaped steel, cement mixing piles are used for water stop, and H-shaped steel is used for retaining soil; ②One row or two rows of cement-soil mixing piles To stop the water, add a row of bored piles to retain the soil; ③Drill multiple rows of cement-soil mix...

AI Technical Summary

Problems solved by technology

[0003] The disadvantages of the ① enclosure method are: the cost of H-shaped steel is high. Due to the long construction period of the basement, the steel-shaped steel is currently rented. The longer the time, the higher the rental fee. In addition, when the pile is pulled out, the machine has no working surface, and the H-shaped steel cannot be pulled out. , can only be scrapped, and the cost is very high; the disadvantages of the second type of enclosure method are: the construction period is long, the bored piles produce a large amount of mud, pollute the environment, the quality is difficult to guarantee, and the cost is also high; the third type of enclosure method only It can be used for excavation depth less than 4m in enclosure engineering
