Device for rapidly chiseling pile head of pile foundation

Abstract

The invention discloses a device for rapidly chiseling a pile head of a pile foundation. The device is characterized in that a reinforcement cage of the pile foundation is provided with a main reinforcement and a sounding pipe, the device comprises a jack and arc-shaped isolation plates matched with the reinforcement cage, the isolation plates are provided with a row of mounting holes allowing the main reinforcement to penetrate through and a plurality of slurry penetrating holes, the isolation plates are discontinuously mounted on the main reinforcements above a designed pile top of the pile foundation, and the isolation plates are obliquely mounted at intervals of the sounding pipes; and a plurality of pre-buried cylinders are arranged on the main reinforcement between the pile top and the isolation plate, the jacks can be placed in the pre-buried cylinders, and the ends, connected with pressure pumps, of the jacks face the inner side of the reinforcement cage. The isolation plate is pre-buried on the reinforcement cage in advance, and an isolation effect is formed between pile top concrete and laitance concrete; and meanwhile, the pre-buried jack jacks the pile head concrete after the concrete is solidified, laitance concrete can be broken, construction is simple, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of bridge engineering pile foundation construction, in particular to a device for quickly digging pile foundation pile heads. Background technique [0002] During the concrete pouring process of the pile foundation, the strength of the concrete on the top of the pile cannot meet the design requirements due to factors such as the coarse aggregate at the top of the pile floating on the surface with the lower layer of its own weight and the slag floating on the surface. Therefore, in order to ensure the strength of the concrete at the top of the pile, overfilling will be performed by 1 meter in actual construction, and the top of the pile will be chiseled off after the concrete reaches the design strength. [0003] There are many traditional methods of chiseling pile heads, but due to various factors, the methods used on site are still: cutting the concrete protective layer, and pneumatic picks to break the con...
