Abstract

The embodiment of the invention discloses a flexible support and a supporting method and relates to the technical field of surrounding rock supporting. The flexible support comprises a hose and a grouting opening device, wherein the grouting opening device is in sealing connection with the end of the hose. The hose is provided with an exhaust device. A cavity in the hose is internally provided with a tensile flexible wire in a penetrating mode. The ends of the tensile flexible wire are fixed to the grouting opening device, or the two ends of the tensile flexible wire are connected with each other. The supporting method comprises the steps of conducting supporting by using the support. The flexible support and the supporting method are suitable for surrounding rock supporting.

Description

technical field [0001] The invention relates to the technical field of support, in particular to a flexible support and a support method. Background technique [0002] Rigid metal brackets are often used in underground engineering, especially mine roadways, secondary support of mine roadways, and mountain tunnels, including U-shaped steel brackets, I-shaped steel brackets, and steel pipe concrete brackets. The common characteristics are: [0003] (1) The bracket is processed and formed on the ground, transported to the ground in multiple arcs, and assembled at the work site, and the installation process is complicated. [0004] (2) The linear density of the support is high, and the installation is difficult. Generally, it is necessary to build a scaffold first and then install the support. The installation speed is slow and the labor intensity of the workers is high. [0005] (3) Most of the brackets are made of steel, the overall weight of the bracket is large, and the cos...
