Embedded part is provided with vertical steel strut on steel strut built-in fitting, inclined bracing members, bracing members is provided on bracing members built-in fitting
The other end be fixedly connected with steel strut；It is disposed with prefabricated SP pre-stress hollow from bottom to up along the axial direction of steel strut
Plate, SP prestressed cored slab are fixedly connected with steel strut.
The length of the SP prestressed cored slab is less than the length between the seat post of both ends.
Seat post basis pile foundation, support column foundation and seat post are separately positioned on four rectangular dots of closing coal yard
On, grid structure is arranged in four seat posts, closes and is provided with coal-stopping wall in two long rectangular edges of coal yard.
The steel strut uses H profile steel.
The utility model has the following beneficial effects: coal-stopping wall provided by the utility model is using SP prestressed cored slab assembly gear
Coal wall greatly reduces field operation construction, construction period and site operation expense is greatly reduced；SP pre-stress hollow is hardened
Structure is high-strength, has saved reinforcing bar and concrete amount, saves project cost.
