Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings.
[0017] The fast hole plugging device for statically removing pile heads of cast-in-place piles is composed of a material storage tank (1), a material guide pipe (2), a stamping rod (3), and a material turning support (5). The material used for plugging holes is a mixture of rapid-setting cement and coarse sand. The rapid-setting cement quickly solidifies and achieves higher strength after being exposed to water. Adding coarse sand can increase the friction between the plugging material and the split hole wall, greatly improving Its plugging effect. The top of the storage tank (1) is provided with a square feeding hole (4) for filling hole-clogging materials, and the bottom is funnel-shaped. The feed pipe (2) is composed of a hollow steel pipe with an inner diameter of 50 mm and a length of 50 mm, and is connected to the bottom of the funnel surface of the storage tank...
