A precast concrete grooved sheet pile head reinforcement device

Abstract

The invention discloses a reinforcing device for a prefabricated concrete channel plate pile head. The reinforcing device comprises a pile body which comprises an upper web and wing plates on the two sides; the upper web is 120 mm in thickness; longitudinal main rebars are laid in the pile body and connected through stirrups; transverse main rebars are arranged in the pile body, and the transverse main rebars and the longitudinal main rebars are fixedly connected through stirrups in the intersecting positions; the pile head is arranged at one end of the pile body, the thickness of a pile head web is 280 mm, a plurality of dense rebars are arranged in the pile head, and the dense rebars and the longitudinal main rebars are arranged in parallel; and the longitudinal main rebars, the stirrups and the dense rebars form rebar grids which are located at the front section of the pile head, three rebar grids are arranged at the intervals of 50 mm, and two rebar grids are arranged at the interval of 100 mm, and five rebar grids are arranged in total. According to the reinforcing device for the prefabricated concrete channel plate pile head, the principles that the dense rebars are small in diameter and are densely arranged are observed, non-uniform stress generated in the vibration pile driving process can be effectively borne, construction is easy to conduct, not only can the pile head be effectively protected, but also a mass of rebars are omitted, and the cost is reduced.

Description

technical field [0001] The invention relates to a method for reinforcing foundation piles, in particular to a high-strength prestressed prefabricated concrete grooved sheet pile head reinforcing device used in construction engineering and structural engineering. Background technique [0002] The existing PHC prestressed pipe piles are hollow in the middle, and the section is a regular ring with a relatively small cross-sectional area. During the piling construction process, the pile head is protected from damage by putting two end plates on both ends destroy. However, due to the large and irregular cross-sectional area of ​​the existing prestressed high-strength sheet piles, even when special steel end plates are used, many pile heads are still damaged to varying degrees during the pile sinking process. The cross-sectional area of ​​the new ecological sheet pile head is larger and the shape is more irregular. Considering that the price of the steel end plate will be higher,...

Problems solved by technology

However, due to the large and irregular cross-sectional area of ​​the existing prestressed high-strength sheet piles, even when special steel end plates are used, many pile heads are still damaged to varying degrees during the pile sinking process.

The cross-sectional area of ​​the new ecological sheet pile head is larger and the shape is more irregular. Considering that the price of the steel end plate will be higher, it will not achieve a good effect.
