Embodiment one:
See also accompanying drawing 1, be the embodiment of the invention one disclosed method flow chart, concrete steps are:
Step S11, preset all kinds of parameter presets before shield machine carries out slip casting, said parameter preset comprise higher limit and lower limit, injection slurries total amount, slurries setting time and automatic scavenging period or the like of slurries injection parameter, Grouting Pipe force value.
In step S11, because shield machine can be operated under the different environment, can select different slurries to inject according to different working environments, so all kinds of parameter presets in the shield machine also can be owing to working environment, and inject the difference of slurries and different.Before shield machine is constructed, as the case may be the parameters such as shield tail void area, slip casting injection rate, the flow-rate ratio of injecting slurries, slurries injection rate, slurries setting time, Grouting Pipe upper pressure limit and automatic scavenging period of shield machine are preset.
Wherein, shield tail void area is S=π (D
2-d
2)/4, D is a shield tail external diameter, d is the tunnel external diameter; Shield machine interlock speed is V, and scope is 0～80mm/min; The slip casting injection rate is σ, and scope is 100%～200%; The flow-rate ratio of injecting slurries A liquid and B liquid is A: B=1: 10.Then,, calculate the total amount Q=S*V* σ that injects slurries through shield tail void area S, shield machine interlock speed V and slip casting injection rate σ, and preset higher limit and the lower limit of injecting the slurries total amount.
Step S12, shield machine injects slurries according to said preset slurries injection parameter.
When execution in step S12, the stroke of the driving jack in the shield machine has reached the position of regulation, and promptly shield machine begins slip casting.In execution in step S12; Utilize the preset slurries injection parameter of obtaining among the step S11, the pump speed in the control shield machine is to reach the preset slurries injection rate that obtains among the step S11; And according to preset slurries injection rate injection slurries; Make the slurries of injection can fill shield tail space timely, support shield machine rock mass or soil layer on every side, guarantee the stable of shield machine operate as normal and shield tunnel.
Need to prove that the said slurries injection parameter of in step S11, obtaining can be manual setting or preset slurries injection rate, also can be the interlock speed of the jack in the shield machine.Shield machine can be selected any in the interlock speed of slurries injection rate or jack in step S12, and the pump speed in the control shield machine reaching the preset slurries injection rate σ that obtains among the step S11, and is controlled the injection of slurries with this.
Step S13, the force value of detection Grouting Pipe judges whether said Grouting Pipe force value surpasses the higher limit of preset Grouting Pipe force value, if, then stop slip casting, then execution in step S14; If, then do not transfer execution in step S15.
