Latest Patents

Xiangbao Meng's latest patents include two methods for treating tunnel collapses. The first patent, titled "Method of treating tunnel collapse using pavilion support," involves leveling a collapse body and moving a pavilion support under the collapse cavity. This method includes lifting a shield plate until its lower edge surpasses the contour line of an initial supporting arch of a tunnel. The process also involves connecting a bottom column and inserting a padding plate under the column. If the hydraulic prop retracts, the column, bottom column, padding plate, and hydraulic prop bear the load from the shield plate. The method concludes with transferring the load of the shield plate from the pavilion support to an initial supporting shed, spraying fast-setting concrete to form a closed shell, and pumping filling material to fill the collapse cavity.

The second patent, "Method of treating tunnel collapse with roof-contacted shield support," describes a process that includes mounting a shield plate, a column, and a support column to form a combined support. This combined support is then moved onto an operation platform and lifted to ensure the height of the canopy exceeds that of the initial supporting arch. The method actively contacts the surface of the collapse cavity with a fixed support column, bearing the load while lifting a movable support column to the top of the collapse cavity. The process also involves mounting an initial supporting arch and welding it with the support column, followed by the removal of a hydraulic prop after the load of the shield plate is transferred to a supporting shed.
