Soil Nailing Wall Equipment for Automatic Tree Trunk Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil nailing wall construction methods are inefficient due to interference from tree trunks extending out of slopes during landslide events, which hinder the installation of grouting rods and reduce construction efficiency.
Innovation Solution
A construction process and equipment for soil nailing walls that includes a telescopic cylinder, cutting assembly, clamping assembly, and reinforcement assemblies to automatically cut and remove tree trunks, allowing for the efficient installation of grouting rods by lifting and tilting mechanisms, preventing tree trunks from falling back onto the slope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing devices directly insert grouting rods into preset holes, then the construction process is simple, but tree trunks extending from slopes interfere with operation and greatly reduce efficiency
Solution Approach 1:
The cutting assembly automatically cuts tree trunks protruding from the slope before grouting rod installation begins. This preliminary removal of obstacles ensures that the subsequent grouting operation can proceed without interference, resolving the contradiction between operational simplicity and construction efficiency
Solution Approach 2:
The cutting assembly acts as an intermediary device between the existing grouting device and the obstructive tree trunks. By introducing this intermediate cutting function, the system can handle obstacles automatically without compromising the simplicity of the overall construction process
2Ease of operation
If tree trunks are manually removed before construction, then interference is eliminated, but construction time and labor costs increase
Solution Approach 1:
The cutting function is merged with the grouting rod installation process by integrating the cutting assembly into the construction equipment. This allows tree trunk removal and grouting installation to be performed in a coordinated manner, eliminating the need for separate manual tree removal operations and reducing total construction time
Solution Approach 2:
The cutting assembly enables the construction equipment to automatically remove obstacles itself during the construction process. This self-service capability eliminates the need for separate manual intervention, thereby reducing both labor costs and construction time while maintaining operational smoothness
3Productivity
If a single-function grouting device is used, then device complexity is low, but it cannot handle tree trunks and reduces efficiency
Solution Approach 1:
The construction equipment is designed with multi-functionality by integrating both cutting and grouting installation capabilities into a single device. The cutting assembly and grouting device work together as a unified system, enabling the equipment to handle both tree trunk removal and rod installation without requiring separate devices, thus improving productivity while maintaining reasonable complexity

AI summary
A construction process of soil nailing wall for geological disaster control is provided, which uses a construction equipment of soil nailing wall for geological disaster control, including underframe, lifting assembly and etc.; a lifting assembly is installed on the left side of the upper side of the underframe. When in use, the disclosure can automatically cut off the tree trunks extending out of the slope surface, and then install the grouting rods in the soil slope holes. At the same time, the disclosure can adapt to the tree trunks with different bending degrees to cut them, which solves the problem of tree trunks interfering with the construction, greatly improves the efficiency, prevents the cut tree trunks from falling onto the slope, avoids damaging the slope surface, and can adapt to a variety of situations to cut off the tree trunks.
