Abstract

An H-shaped supporting pile made of prefabricated reinforced concrete comprises an H-shaped hoop and an H-shaped standard reinforced concrete pile section, wherein the H-shaped hoop is formed by a steel reinforcement framework, provided with an H-shaped section and comprises a vertical stirrup, a triangle frame hoop and an 'S'-shaped stirrup, the bottom edges of the triangle frame hoop are connected with a plurality of main reinforcement ribs longitudinally, the inner side of the 'S'-shaped stirrup is connected with longitudinal inner reinforcement ribs longitudinally, wedge-shaped recesses are arranged on both the left and the right side of the H-shaped hoop, and two ends of the H-shaped standard reinforced concrete pipe section are provided with pile head portions. The H-shaped supporting pile is provided with the optimum section characters of a horizontal force resistant pipe for bearing side earth pressure, and the steel reinforcement ribs and concrete can be obviously saved; industrialized production of shaped commercial piles is realized, pile sinking efficiency is improved, and labor force is reduced; and construction of high-pressure spinning spraying piles between every two piles is realized, anti-seepage probability is improved since cement slurry sprayed by the high-pressure spinning spraying piles is restrained by the H-shaped section.

Description

technical field

[0001] The invention relates to a pile foundation of civil construction engineering, in particular to a support pile which can withstand relatively high horizontal lateral earth pressure in deep foundation pit engineering, and can reduce foundation pressure in foundation pit enclosure engineering. Prefabricated reinforced concrete I-shaped support piles for pit engineering cost. Background technique

[0002] At present, the supporting piles used in deep foundation pit engineering usually adopt bored cast-in-place piles or immersed pipe cast-in-place piles, and the bored cast-in-place piles or immersed pipe cast-in-situ piles usually adopt the construction method of site-cast piles; the cast-in-place piles Even if the construction method is fully completed, the foundation groove can only be excavated after the concrete of the cast-in-place pile reaches the specified strength; therefore, the construction efficiency of the current bored pile or immersed pipe pil...
