Cast-in-place pile head processing method and a cast-in-place pile with a fast-dismounting pile head

Abstract

The invention discloses a cast-in-place pile head processing method and a cast-in-place pile with a fast-dismounting pile head, and relates to the field of water conservancy projects. The constructionstep comprises the following steps that 1, a cast-in-place pile steel bar framework is arranged in a pouring hole; 2, a steel bar sleeve pipe is arranged on a vertical reinforcing steel bar of a pilebody part, and a vertical steel bar is transversely arranged on a stirrup on the top end of the pile body part; 3, a hollow groove mold plate is installed on the vertical steel bar; 4, concrete is poured into the pouring hole to form a pile; 5, a jack is arranged in the hollow groove mold plate, and the jack is lifted to the position where a pile head and the pile body forms a bed joint; and 6, pile head concrete is fixed through a hollow groove in the hollow groove mold plate and the bed joint, and the pile head concrete is vertically separated from the pile body. The processing method and the cast-in-place pile have the advantages that operation is simple and convenient, and the construction efficiency is high; and the steel bar safety can be protected, and the quality of the pile bodycan be guaranteed.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a method for treating cast-in-place pile heads and quick-detachable pile-head cast-in-situ piles. Background technique [0002] During the construction of pile foundation concrete, laitance is prone to occur due to the sinking of the concrete coarse aggregate at the top of the cast-in-place pile. It often leads to poor concrete strength at the pile head, and the height of the pile top is not easy to control during the pouring of cast-in-place piles. In order to ensure the concrete strength of the pile body and the elevation of the pile top, in the prior art, the height of the pile is usually higher than the elevation required by the design when pouring the pile, and then the excess part is manually chiseled to reach the elevation of the design. There is not a kind of simple and easy special processing device in pile head chiseling construction. [0003] In the prior...
