| titleOfInvention | A kind of underground engineering support antiknock integration composite construction |
| abstract | The invention belongs to underground protective engineering fields, specially a kind of underground engineering support antiknock integration composite construction, be divided into three-decker from outside to inside: outermost layer is bolt grouting reinforcing layer, grouted anchor bar is anchored in the weak surrounding rock layer around underground passage and carries out slip casing by pressure, it fills original in weak surrounding rock layer and because of crack caused by roadway excavation, it is bonded as entirety, enhances whole resistance to compression and shear strength, while playing the role of preventing underground water in rock stratum around from leaking；Middle layer is gunite concrete reinforcing layer, one layer of pea gravel concreten spray-up for being anchored on rock layer surface around tunnel is formed using Spray Gun Of The Pressure, tunnel top and two sides country rock are linked as entirety, and fill up the irregular joint on country rock surface, provides smooth mounting surface for the installation of later period antiknock plate；Innermost layer is prefabricated assembled antiknock composite plate, can effectively resist and absorb explosive forces, while improve the globality of structure.The present invention plays an important roll supporting and the antiknock protection of mining tunnel, underground chamber. |
