Microorganism seepage-proofing grouting device and method of lining segment of river-crossing tunnel
The invention discloses a microorganism seepage-proofing grouting device and method of a lining segment of a river-crossing tunnel. A first conveying pipe and a second conveying pipe are arranged in aperipheral water-rich soil layer of the river-crossing tunnel, wherein one end of the first conveying pipe communicates with a first container, one end of the second conveying pipe communicates witha second container, and the other end of the first conveying pipe and the other end of the second conveying pipe are sealed. A first grouting hole and a second grouting hole are formed in the positions, at least corresponding to the to-be-blocked lining segment area, of the first conveying pipe and the second conveying pipe. In the grouting process, though the water head differences between the interiors of the first container and the second container and river water corresponding to the positions of the river-crossing tunnel, a first mixed solution and a second mixed solution are promoted toflow into the peripheral water-rich soil layer of the river-crossing tunnel through the first grouting hole and the second grouting hole and are slowly annularly diffused and mixed along the peripheryof the river-crossing tunnel, finally microorganism slurry in the first mixed solution and a nutrient solution in the second mixed solution react so as to form a layer of annular biogel reinforcementband wrapping the lining segment from the periphery, and therefore gaps between the lining segments are blocked.
本发明公开了一种过江隧道衬砌管片的微生物防渗注浆装置及方法，其在过江隧道外围富水土层中环向间隔设有一端分别与第一容器和第二容器通连，另一端封闭的第一输送管和第二输送管，并在第一输送管和第二输送管至少对应待封堵衬砌管片区域分别开设有第一注浆孔和第二注浆孔，注浆过程中，利用第一容器内部和第二容器内部与过江隧道各处对应的江水的水头差，促使第一混合液和第二混合液分别经第一注浆孔和第二注浆孔流入过江隧道外围的富水土层，并缓慢地沿过江隧道的外围环向扩散及混合，最后由第一混合液中的微生物浆液和第二混合液中的营养液进行反应，以形成一层从外围将衬砌管片包裹的环形的生物凝胶加固带，从而将衬砌管片之间的缝隙封堵。
