Siping acoustic pipe grouting pipe settlement plate manufacturer - Xiaoshen nationwide delivery Siping grouting pipe + Siping acoustic pipe Siping settlement plate manufacturer - The understanding of the support mechanism of Siping bridge acoustic pipe needs to be improved
Currently, Siping is used The design methods of bridge acoustic tubes are calculated using the theories of suspension, composite beams, reinforced arches, etc. They are all proposed for general tunnels. It is not possible to establish a support principle and design that meets the characteristics of the specific conditions of the Siping bridge acoustic tube tunnel. The method is especially the requirements for the design of acoustic tubes for all-Siping bridges and tunnel surrounding rock support under soft rock conditions. Therefore, the current technical standards are mainly empirical and there is still a lot of blindness in design and construction. Therefore, it is necessary to explore the acoustic pipe support theory of Siping Bridge on the basis of further in-depth study of the appearance of mine pressure in the surrounding rock of the tunnel.
2. The product quality of the Siping Bridge Acoustic Detection Pipe and the anchoring agent is not up to standard, and the Siping Bridge Acoustic Detection Pipe equipment is not matched
The material, structure and mechanical properties of the Siping Bridge Acoustic Detection Pipe are closely related to the quality index of the anchoring agent. It is also the key to determining the reliability of support. There are many types of Siping Bridge Acoustic Detection Tubes used underground in my country, but their strength and elongation are low. They cannot provide large support resistance for the surrounding rock of the roadway, and they cannot adapt to the deformation of the surrounding rock of the roadway and are easily damaged. The tunnel roof is separated or moved. In addition, due to the use of low-performance acoustic pipes, the number of installed acoustic pipes per meter of tunnel will inevitably be too high, which will affect the tunnel excavation progress.
3. Siping Bridge Acoustic Pipe Testing Machines and Tools Are Not Matched
The performance of Siping Bridge Acoustic Pipe Testing Machines and Tools is the key to determining the installation quality and construction speed of Siping Bridge Acoustic Pipe Testing Pipe. Australia not only attaches great importance to the development of structural types of acoustic pipes for various specific purposes, but also attaches great importance to the continuous development and update of drilling and installation machines for acoustic pipes. Although our country currently has electric, pneumatic and hydraulic Siping bridge acoustic pipe drilling rigs, the performance and structure are not reasonable. The quality of parts and the performance of the whole machine are in urgent need of further improvement and improvement. As for the anchor digging and anchoring combined unit, further intensification of development and testing is needed. Implement parallel operations of excavation and branching to increase tunnel construction speed.
