Construction method for conducting magnetic grout grouting on pipe shed and advanced small guide pipe
The invention provides a construction method for conducting magnetic grout grouting on a pipe shed and an advanced small guide pipe, and the improvement comprises the steps that when an advanced curtain is grouted, and the pipe shed and the advanced small guide pipe are grouted, magnetic floral tubes are placed in grouting holes and steel pipes, and a power source is externally connected to control the magnetism of a magnetic field; and adding water-borne epoxy resin, a curing agent, magnetic powder and other materials into the cement slurry, and uniformly stirring to prepare the magnetic cement slurry. According to the improved magnetic cement grout, the grout can be evenly diffused in gaps or cracks of surrounding rock, the diffusion range is effectively reduced, grout leakage and grout runout can be prevented, the interior of a steel pipe can be rapidly filled with the grout, gas in the grouting pipe can be better discharged, and the grouting effect is good. And the injected magnetic cement grout can be bonded with surrounding rock in an effective range to form a more stable concrete consolidation body, so that the stability of the surrounding rock is better improved, meanwhile, better water resistance is achieved, and the safety of tunnel construction is guaranteed.
本发明提供了管棚和超前小导管进行磁性浆液注浆的施工方法，该改进包括对超前帷幕注浆、管棚和超前小导管注浆时，向注浆孔、钢管内放置磁性花管，外部接电源，来控制磁场磁性大小，再对水泥浆液中加入水性环氧树脂、固化剂、磁粉等材料搅拌均匀来制备磁性水泥浆液。并对所述的超前帷幕注浆孔、管棚和超前小导管进行注浆操作，此改进的磁性水泥浆液能使注浆液在围岩空隙或裂隙中扩散均匀，有效的减小扩散范围，能防止漏浆和跑浆，还能使注浆液迅速的填充钢管内部，能更好排出注浆管内的气体等，使注入的磁性水泥浆液能与有效范围内的围岩粘合而形成更加稳定的混凝土的固结体，从而更好增加围岩的稳定性，同时更好的防水，保障隧道施工的安全性。
