Abstract

The invention relates to the technical field of roadway support, in particular to a gob-side entry confined concrete supporting side protection system, comprising confined concrete supporting columns,longitudinal connecting devices and lateral side protection devices. Each confined concrete supporting column is provided with an automatic lifting device at the bottom end. The top end of each confined concrete supporting column is used for supporting the top of a roadway. Each automatic lifting device is used for adjusting the distance between the top end face of the corresponding confined concrete supporting column and the top of the roadway. The plurality of longitudinal connecting devices are mounted between the adjacent confined concrete supporting columns. The longitudinal connecting devices have set gaps therein. The lateral side protection devices are mounted in the set gaps. Two vertical ends of the lateral side protection devices are connected respectively with the confined concrete supporting columns. The gob-side entry confined concrete supporting side protection system of the invention conforms to the characteristics of being detachable recycling and reuse, can reduce the construction cost and improve the construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of roadway support, and in particular relates to a gob-side roadway retaining gangue support constrained concrete roof support system. Background technique [0002] When the gob-side roadway is formed, in order to prevent the gravel in the goaf from pouring into the entry retention and affect the coal mining process, it is necessary to carry out gangue support for the gravel in the goaf. At present, the commonly used gangue retaining measures are mainly U-shaped steel brackets and metal meshes to initially block the crushed stones along the side wall, and then adopt axial compression such as top-cutting support brackets and plain concrete columns on the outside of the U-shaped steels and metal meshes. The bearing device supports the roof of the roadway. [0003] Under this kind of support scheme, the sequential erection and installation of reinforcement mesh, U-shaped steel and axial pressure bearing device...
