AUGUST 2018 PATENT JOURNAL in a mud rock matrix to be closed, substantially hinders microcosmic effects such as adsorption, dissolution and weathering, improves the compactness and integrity of microstructures of the mud rock, reduces the permeability, and improves the deformation resistance and durability of the rock mass. 21: 2017/03599 22: 2017/05/25 43: 2018/06/04 51: E21D 71: China University of Mining and Technology 72: ZHANG, Nong, PAN, Dongjiang, XIE, Zhengzheng 21: 2017/03600 22: 2017/05/25 43: 2018/06/06 33: CN 31: 201510603025.5 32: 2015/09/21 51: B66B 54: SILICA SOL SLOW INFILTRATION 71: China University of Mining and Technology REINFORCING METHOD FOR ARGILLACEOUS 72: CAO, Guohua, YAN, Lu, ZHU, Zhencai, QIN, SOFT ROCK Jiancong, PENG, Weihong, GAO, Yuan, WANG, Lei, 00: - MA, Yiping 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).
