Rapid hole plugging device for static breaking of pile head of cast-in-place pile and using method

Abstract

The invention discloses a rapid hole plugging device for static breaking of a pile head of a cast-in-place pile, and belongs to the field of building construction. The rapid hole plugging device for the static breaking of the pile head of the cast-in-place pile is designed for solving the problem of plugging of a split hole in a static splitting breaking project of the pile head. The device is composed of a material storage tank, a material guide pipe, a stamping rod and a material turning support. Material for plugging the holes is a mixture of rapid setting cement and coarse sand. The top of the material storage tank is provided with a square hole for filling a hole plugging material, and the bottom of the material storage tank is funnel-shaped. The material guide pipe is composed of a hollow steel pipe with the inner diameter of 50 mm and the length of 50 mm, and the material guide pipe is connected to the bottom of the hopper face of the material storage tank. The stamping rod is composed of a steel pipe with two closed ends and the outer diameter of 45mm, and a transverse handheld rod is arranged at the top of the stamping rod. The material turning support is connected to the stamping rod and arranged in a crossed mode. The device can be used for rapidly and continuously putting the hole plugging material into a cleavage hole and vibrating and compacting the hole plugging material. The pile head breaking efficiency is improved, the engineering quality can be guaranteed, and good economic benefits are achieved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a fast hole plugging device for static removal of cast-in-place pile heads. Background technique [0002] In the cast-in-situ pile pouring project, the elevation of concrete pouring is generally about 500mm higher than the design elevation of the pile top to ensure that the strength of the pile head can meet the design requirements. It is a difficult problem in the engineering field. Commonly used pile head demolition methods are usually accompanied by noise and dust pollution. The efficiency of manual demolition is low, and blasting demolition can easily cause damage to the lower pile body. Static splitting technology has unique advantages in rock and concrete demolition engineering because of its friendly construction environment. It is a new technical solution to apply it to the demolition of pile heads. However, the internal heat of the splitting agent usuall...

Problems solved by technology

However, the internal heat of the splitting agent usually accumulates sharply due to the rapid hydration reaction, which eventually leads to spray holes, which seriously affects the performance of the splitting agent and limits the application of static splitting technology in the removal of cast-in-situ pile heads
