Combined multi-ring and multi-hole construction device and method for intercepting cement concrete pile heads

Abstract

The invention discloses a combined multi-ring and multi-hole construction device for intercepting cement concrete pile heads, and belongs to the technical field of intercepting cement concrete pile heads. The combined multi-ring and multi-hole construction device comprises a multi-ring and multi-hole ring body, wherein a fabricated power column is movably arranged at the circle center in the multi-ring and multi-hole ring body, a plurality of supporting frames are fixedly arranged to the circumference outer wall of a connecting sleeve in the ring array mode, the top part of the fabricated power column penetrates through a roof plate and extends to the bottom of an inner cavity of a shell, and a blade adjusting water injection mechanism in conjunction with four groups of blades and a hollowsteel sheet mechanism is movably arranged on the top part of the fabricated power column. The combined multi-ring and multi-hole construction device for intercepting the cement concrete pile heads adopts the blade adjusting water injection mechanism, a servo motor is driven according to the position of steel bars, through the rotation of a thread rod, a circular table movable block is downward, when the circular table movable block is downward, the blades around the circular table movable block are jacked and separately move outwards, the truncation area of the blades is adjusted to flexiblyadapt to the truncation of the concrete pile heads with different diameters, the quality of segmentation is greatly improved, and at the same time, the quality and efficiency of subsequent treatment of excess concrete materials are conveniently treated.

Description

technical field [0001] The invention relates to the technical field of cutting off cement concrete pile heads, in particular to a combined multi-ring and porous construction device and method for cutting off cement concrete pile heads. Background technique [0002] During the pouring of cast-in-place concrete piles, due to 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, whi...

Problems solved by technology

[0003] At present, the combined cutting of cement concrete pile heads is usually done manually with a pick or other cutting equipment to remove the useless concrete above the pile level, and then strip the main reinforcement in the reinforcement cage. This method is time-consuming, laborious, inefficient, and easy to use. Excessive bending of steel bars, and a large amount of dust are likely to be generated during the chisel removal process, which not only pollutes the environment, but also poses a greater health hazard to construction workers
