Problems solved by technology

[0002] In modern buildings, the prefabricated cement piles are driven into the ground by a pile driver in the foundation part. The lower end of the most advanced pile is conical, which is convenient for going down, but there is also a load after completion. When it is enlarged, there is a danger of sinking and causing the house to deform and collapse

Embodiment Construction

[0004] A cavity is designed in the pointed cone of the section pile, and a remote control receiver and an appropriate amount of explosives are installed. After the piling project is completed, the explosives at the end are remotely detonated to form a circular pit with the explosives as the center of the circle. Because there is a through hole of about 10cm in the middle of the cement pile to the bottom, so the concrete is injected from the hole to the bottom to form a large round pier, which prevents the pile from settling, increases frictional resistance, and ensures the safety of the house.

Abstract

The invention relates to an explosive underpiling. A remote receiver and a right amount of explosive material are arranged at the top end of a first pile, and the explosive material is detonated after piling works are completed. Then, concrete is poured into a hole in the center of the pile to prevent the underpiling from sinking.

Description

technical field [0001] The invention relates to an explosive ground pile in the underground part of the construction field. Background technique [0002] In modern buildings, the prefabricated cement piles are driven into the ground by a pile driver in the foundation part. The lower end of the most advanced pile is conical, which is convenient for going down, but there are also loads after completion. When it is enlarged, there is a risk of sinking and causing the house to deform and collapse. Contents of the invention [0003] The invention is a device designed for the purpose of changing the structural shape of the lower top end after the construction is completed, because the lower end must be in the shape of a pointed cone during piling, which is safe, reliable, and easy to implement. detailed description [0004] A cavity is designed in the pointed cone of the section pile, and a remote control receiver and an appropriate amount of explosives are installed. After t...
