In the present invention one broad embodiment, a kind of rich water diabase and slate is irregular invades rock shield structure sediment improvement method mutually, by the position, hole on cutter head panel filling passage and each spoke arm in shield cutter front, adopt polymer loading system to dregs filling high additive high molecular polymer, meanwhile by the filling passage in native storehouse and position, hole, foam mix generation systems is adopted to carry out compound filling to concentration foam in dregs filling.
Sediment improvement material generally has surfactant-based (as foaming agent), mineral substance (as clay or swell soil), high score subclass (as polymer) and other compound adding materials.Its filling position is generally the injection hole be distributed on cutter head panel, native storehouse dividing plate and screw machine cylindrical shell, its material selection and charging method should consider according to the characteristic sum Suporting structure ability on driving stratum and configuration feature, generally compound should be taked to add for bad ground, the principle that multipath injects, namely two or more additive material is chosen, suitable position, hole is selected at cutterhead, Tu Cang and screw machine place, according to rational dispense path, according to respective add-on system and approach, combine injection, to obtain good improved effect simultaneously.
Shield driving sediment improvement high molecular polymer additive material is divided into insoluble and water-soluble two large classes.
Insoluble polymer is mainly: super absorbent resin class (SuperAbsorbentPolymer, be called for short SAP), also super-absorbent material is claimed, high water absorbency polymer, is mainly divided into starch based, cellulose family, synthetic polymer class (polyacrylic, polyvinyl alcohol, polyoxyethylene) three major types according to raw material sources.Polyacrylate is commonly used during shield-tunneling construction sediment improvement.This family macromolecule has high-hydroscopicity, characteristic such as pressurization water retention, thickening property etc., after water suction, volume is inflatable to tens of to thousands of times, its water sucting mechanism is mainly physical absorption (absorption principle of capillary tube, when having pressure, water can flow out) and (by the mode of chemical bond, water and hydroaropic substance is combined into as a whole with chemisorbed.Pressurization can not be released water).
Water-soluble polymer: also claim water-soluble high-molecular material, is mainly divided three classes: water-soluble macromolecule, mainly contains starch based, seaweeds etc.; Semi-synthetic water soluble polymer, mainly contains modified cellulose (CMC etc.), modified starch; Synthesizing water-solubility macromolecule, mainly contains polymer resin (polyacrylamide, polyacrylic acid, polyethylene glycol, polyethylene glycol oxide etc.), condensation resinoid (epoxy resin, polyurethane resin etc.).Polyacrylamide (PAM) is commonly used during shield-tunneling construction sediment improvement.Hydrophilic radical in water-soluble polymer not only makes it have water-soluble, but also has chemical reaction function, and the multiple physical function such as dispersion, flocculation, thickening, drag reduction, bonding, film forming, plastic, chelating.There is water-soluble, peptizaiton, flocculation, tackifying, drag reduction effect, rheological characteristic, suspension effect etc.
When polymer solution adds in the soil body, polymer expands because of water suction, makes the soil body become dry, prevents the generation of gushing; The molecule in the soil body can be connected, strengthen the viscosity of excavation face water and soil, reduce soil body permeability; Improve dregs stream plasticity, the lubrication soil body also helps in conveying worm, form soil plug effect; Lower the adhesion strength of the soil body and knife disc tool.
Shield structure high molecular polymer is a kind of flowable liquids with certain viscosity of formulated homogeneous at the scene, through Cemented filling in cutterhead, Tu Cang, conveying worm, thus increase the viscosity of quarrel soil, improve the working environment of cutterhead, increase the sealing of Tu Cang and be convenient to the transport of quarrel soil.
High molecular polymer can produce following effect: make the shield structure front soil body even after injecting the soil body; Strengthen the slump of soil; Reduce the water permeability of soil, play the effect of water proof; Reduce cutter head torque, reduce facility wearing and tearing; Reduce the viscosity of soil, prevent " mud cake " phenomenon.For solving the creeping of sandy soil, changing the composition of soil, to ensure the mobility of soil and to reduce the water permeability of soil, making excavation face keep stable.
High molecular polymer is used for the effect of shield structure sediment improvement:
