Construction method for removing excess wet concrete of unset concrete pile

Abstract

The invention relates to a construction method for removing excess wet concrete of an unset concrete pile. The method is characterized by comprising the following steps of S1, pouring concrete, specifically, pouring the concrete into a concrete mold to an elevation; S2, adjusting a circular through hole, specifically, rotating an annular piece corresponding to the bottom face of a multi-ring multi-hole circular ring body according to the position of a steel bar, and adjusting the circular through hole corresponding to the steel bar; S3, placing a device; S4, protecting the steel bar; S5, carrying out pile head supplemental pouring; S6, leveling the device, specifically, starting a micro vibration machine on a corresponding rectangular steel sheet according to the specific construction condition, and leveling the device; S7, spreading fan-shaped blades out; and S8, recovering waste and cleaning the device. According to the method, the fan-shaped blades are used in combination with the multi-ring multi-hole circular ring body, the wet concrete can be cut integrally, the circular through hole in the annular piece is used in cooperation with an elliptic hole in the multi-ring multi-hole circular ring body, and the method can be suitable for concrete piles with various steel bar numbers, positions, diameters and distribution, and is high in flexibility and wide in application range.

Description

technical field [0001] The invention belongs to the technical field of building and bridge construction, and in particular relates to a construction method for cutting excess wet concrete from uncured concrete piles. Background technique [0002] During the pouring process of cast-in-place concrete piles, due to the vibration, the cement slurry will return upwards and rise together with the air bubbles inside the concrete, forming laitance within a certain range on the top of the pile, so the strength of the concrete at the pile head is difficult to guarantee; When the concrete is placed, the mud and mortar mixture at the pile head will accumulate the most, resulting in loose concrete at the pile head, and the strength cannot meet the requirements. Therefore, during the construction of concrete pouring piles, the actual elevation of the pile head is required to be 500-1000mm higher than the design elevation, and the higher part is removed manually or mechanically, which is u...
