Embodiment 1
[0032] A method for reinforcing flexible drainage bamboo fiber rods for slumping disease in underground soil ruins under humid environment, comprising the following steps:
[0033] (1) Process the bamboo pole material into a diameter The bamboo fiber rod is used as the core material 1 of the flexible drainage bamboo fiber rod 5, and the length is 0.5m; and the chemical solution method is used to carry out anti-corrosion and anti-corrosion treatment;
[0034] (2) Geotextile / cloth drainage structure layer: take bamboo fiber pole as the core material 1 and wrap three layers of geotextile / cloth from the inside to the outside as the drainage structure layer; the structure settings and functions of the three layers of civil fabric / cloth are: the innermost The layer is a geotextile 2 with a thickness of 0.1mm, which is firmly bonded to the bamboo fiber rods with adhesives such as epoxy resin, in order to increase the grip force of the interface; -1 ~10 -2 cm / s) non-woven geotextil...
Embodiment 2
[0037] (1) Process the bamboo pole material into a diameter The bamboo fiber rod is used as the core material 1 of the flexible drainage bamboo fiber rod 5, and the length is 2.0m; and use asphalt to boil for a period of time to carry out anti-corrosion treatment;
[0038] (2) Geotextile / cloth drainage structure layer: take bamboo fiber pole as the core material 1 and wrap three layers of geotextile / cloth from the inside to the outside as the drainage structure layer; the structure settings and functions of the three layers of civil fabric / cloth are: the innermost The layer is a geotextile 2 with a thickness of 0.5mm, which is firmly bonded to the bamboo fiber rods with adhesives such as epoxy resin, in order to increase the grip force of the interface; -1 ~10 -2 cm / s) non-woven geotextile 3 (thickness about 2mm), the purpose is to play a role in proper drainage and decompression in the soft plastic-flow plastic site soil, and improve the undrained shear strength of the site...
Embodiment 3
[0041] (1) Process the bamboo pole material into a diameter The bamboo fiber rod is used as the core material 1 of the flexible drainage bamboo fiber rod 5, and the length is 1.0m; and use asphalt to boil for a period of time to carry out anti-corrosion treatment;
[0042] (2) Geotextile / cloth drainage structure layer: Bamboo fiber poles are used as the core material 1 and three layers of geotextile / cloth are wrapped from the inside to the outside as the drainage structure layer; the structure settings and functions of the three layers of civil fabric / cloth are: the innermost The layer is a geotextile 2 with a thickness of 0.3 mm, which is firmly bonded to the bamboo fiber rods with adhesives such as epoxy resin, in order to increase the grip force of the interface; -1 ~10 -2 cm / s) non-woven geotextile 3 (thickness about 2mm), the purpose is to play a role in proper drainage and decompression in the soft plastic-flow plastic site soil, and improve the undrained shear strengt...
