        Provided is a silica sol slow infiltration reinforcing   33: CN 31: 201510566856.X 32: 2015/09/08
        method for argillaceous soft rock, comprising the     54: CHAIN DRIVING APPARATUS OF TWO-WAY
        following steps: a. lithological changes, pore        CIRCULATION CONVEYING SYSTEM
        development characteristics and hydrogeological       00: -
        conditions of roadway surrounding rock are            Present invention discloses a chain driving
        evaluated, and grouting hole (1) parameters and       apparatus of a two-way circulation conveying system
        silica sol ratio are determined; b. grouting holes (1)   comprising a power device, a transmission system, a
        are constructed before argillization, grouting pipes   tension device (7) and a driving chain (11). The
        (2) are mounted and the holes are sealed, and silica   transmission system includes a driving chain wheel
        sol is injected, and in the same time period the silica   (3), a driven chain wheel (4), a reverse gear wheel
        sol quickly fills and reinforces macrofissures under   (10), a driving chain wheel shaft 1 (12), a driving
        the drive of a grouting pressure; and c. when the     chain wheel shaft 2 (9), a driven chain wheel shaft 1
        grouting pressure is reduced to a certain value, and   (5), a driven chain wheel shaft 2 (6) and a mounting
        the low pressure is maintained for a long time, and in   base (8). The driving chain wheel shaft 1 (12), the
        the same time period the silica sol slowly diffuses   driving chain wheel shaft 2 (9), the driven chain
        and enters microfissures of the rock mass under the   wheel shaft 1 (5) and the driven chain wheel shaft 2
        drive of a capillary force to form a highly-compact   (6) are each fixed and mounted on the mounting
        reinforced mass, such that the reinforcing of the     base (8). The driving chain wheel shaft 1 (12) is
        surrounding rock is complete. The method not only     connected with the power device, and the driving
        has the macrofissures filled, but also enables        chain wheel shaft 2 (9) is connected to the driving
        microchannels of water molecules and air molecules    chain wheel shaft 1 (12) through a pair of the
                                                              reverse gear wheels (10). The driving chain wheel
