Problems solved by technology
Pile foundation construction is essential. At present, in the construction industry in Guangxi and even the whole country, most of the pile heads are removed by crushing. The construction efficiency is low, the cost is high, and the working conditions of the workers are difficult. No recycling value

Abstract
The invention discloses a cast-in-place concrete pile head free of crushing and separating. The cast-in-place concrete pile head comprises a cast-in-place pile reinforcement cage and cast-in-place concrete, wherein longitudinal reinforcements and stirrups are arranged at the pile foundation part of the cast-in-place pile reinforcement cage; the longitudinal reinforcements are arranged at the pilehead part of the cast-in-place pile reinforcement cage; longitudinal separating sleeves are mounted on the longitudinal reinforcements of the pile head part of the cast-in-place pile reinforcement cage in a sleeving manner; transverse separating sleeves are arranged at the bottom of the pile head part of the cast-in-place pile reinforcement cage and are arranged in the shape of the Chinese character jing, and vacant positions for placing concrete guide pipes are left in the center; and sleeve protecting reinforcements are arranged in the transverse separating sleeves. The cast-in-place concrete pile head is simple in construction and low in cost, can rapidly separate the cast-in-place concrete pile head by adopting the integral separation manner, is high in efficiency and free of noise anddust, can be integrally recycled to be used as a balancing weight of a following pile foundation static loading test, can be recycled to be used as the brickmaking raw material through mechanical pulverization and is wide in market application prospect.
Description
technical field [0001] The invention relates to the technical field of concrete pouring piles, in particular to a broken and separated concrete pouring pile head. Background technique [0002] All high-rise and ultra-high-rise buildings often use concrete pouring piles as the foundation of the building, and the foundation of bridges is even more indispensable. The cast-in-situ piles used as the foundation of a building range from hundreds to thousands, and the number is huge. During the construction of reinforced concrete cast-in-situ piles, the code stipulates that the top elevation of the poured-in-place piles should be 0.5-1.0m higher than the designed pile top elevation to ensure the quality of the pile head concrete. Unavoidable quality defects can only be eliminated, and cannot be directly used as the pile top, but the pile head part that is higher than the design elevation of the pile top can only be chiseled out in the subsequent construction process after the concr...
