Hollow Prefabricated Wall Elements with Self-Hardening Fill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional prefabricated walls in soil construction are costly and logistically challenging due to the need for prefabrication workshops and expensive transportation of heavy reinforced concrete elements, which also results in significant excavation and material removal.
Innovation Solution
A method involving prefabricated elements with hollow sections connected by metal elements, filled with self-hardening material, reducing transportation weight and costs, and utilizing self-hardening slurry or soil mixing techniques to minimize excavation and material removal, while maintaining structural integrity and aesthetic qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional reinforced concrete prefabricated elements are used, then structural strength and aesthetic qualities are maintained, but transportation costs and weight increase significantly
Solution Approach 1:
The patent employs hollow prefabricated elements with internal cavities that are filled with self-hardening material. This creates a porous-like structure that significantly reduces the weight of the prefabricated elements while maintaining structural integrity through the combination of hollow sections and infused material.
Solution Approach 2:
The patent combines multiple materials: the prefabricated hollow elements are filled with self-hardening material (which may be soil-cement mix or other stabilizing materials). This composite approach allows the structure to achieve the necessary strength while using lighter materials compared to solid reinforced concrete.
2Strength
If heavy reinforced concrete elements are transported to site, then structural integrity is ensured, but transportation costs and logistics complexity increase
Solution Approach 1:
By creating hollow elements filled with light self-hardening material rather than transporting solid reinforced concrete, the patent dramatically reduces the weight and volume of materials to be transported, simplifying logistics while maintaining structural integrity through the hollow-section design.
3Strength
If conventional prefabricated walls are constructed, then wall strength is achieved, but material removal and excavation volume increase
Solution Approach 1:
The patent changes the physical state and composition of the filling material by using self-hardening material that transforms from a soft, pumpable slurry into a hardened state within the hollow sections. This parameter change allows the material to provide structural support while minimizing the volume of material that needs to be removed after construction.

AI summary
A method for making a wall in soil. The method may include forming a trench in the soil; filling the trench with a self-hardening material; supplying at least one prefabricated element that has two plates connected together by a connection member; and positioning the prefabricated element in the trench filled with the self-hardening material.
