Explosion-enlarging stake construction process

Abstract

The invention relates to a method for constructing explosive-forming pile, which comprises: first, digging one horn well mouth at the soil; then at the center of well mouth, downwards drilling vertical tile hole to preset depth; arranging integrated drug pack into hole bottom; arranging sleeve at the center of borehole; filling bar drug pack into sleeve; filling mixed concrete or cement sand pulp between the borehole and sleeve; covering steel plate at the open of borehole; stacking carrier matter on the steel plate; exploding the drug pack and bar drug pack, after 3-8 hours when the filled concrete or cement sand pulp are poured, to form tile post and tile head with concrete protective layer; pouring concrete into tile head and tile post to form explosive-forming pile. The invention has simple process and better forming effect without reducing radius and sink hole.

AI Technical Summary

Benefits of technology

This new method uses special chemical agents that help create strong structures from cast iron or steel bars called breeches. These chemically treated materials react when exposed to water causing them expand upward like rocks. By adding these chemical agents along with other ingredients on top of this expanded material, it becomes more rigid overall. Overall, this innovation helps make stronger buildings faster than traditional methods due to its use of specific types of chemical agents and unique design techniques.

Problems solved by technology

Technological Problem: Exploring this type of technical problem with current methods for creating an underground structure called Piling Concrete (PC) involves excavating holes on top of it that needs to be filled afterwards before being used again. These techniques have issues like cracked walls caused by pressure from heavy equipment hitting them while filling these spaces between layers. Additionally, there may still remain some residue left behind after each step of digging up the ground surface.
