Title: Jiufang Xiong: Innovator in Tunnel Collapse Treatment
Introduction
Jiufang Xiong is a notable inventor based in Qingdao, China. He has made significant contributions to the field of tunnel engineering, particularly in methods for treating tunnel collapses. With a total of 2 patents, his work showcases innovative solutions to complex engineering challenges.
Latest Patents
Jiufang Xiong'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 and filling the collapse cavity with material.
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 exceed the height of the initial supporting arch. The method actively contacts the surface of a collapse cavity and bears the load, while also involving the installation of an exhaust pipe and a filling material pumping pipe to fill the collapse cavity space.
