Description
Technical field
The utility model relates to shield structure two fluid grouting field, relates in particular to a kind of shield structure dual-fluid synchronous slip casting control system.
Background technology
At present, the grouting amount of two fluid grouting can not accurately be controlled, and sometimes can occur because injecting the excessive or not enough engineering accident causing.And because mortar grouting pump is when moving, it is taken out between slurry action and slip casting action and has the spacer segment time, makes slurries in pipeline become pulse type to be fed forward, thereby is unfavorable for the even mixing of mortar and accelerating admixture.In the process of slip casting, because the characteristic grouting pipeline that mortar and biliquid slurry easily solidifies can frequent blockage phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of dual-fluid synchronous slip casting control system, can realize the accurate control to shield structure two fluid grouting, and can greatly reduce the phenomenons such as plugging in slip casting process and incomplete mixing.
The utility model adopts following technical proposals:
The utility model comprehensively judges system feedback data and shield structure running status by PLC, can realize the accurate control to shield structure two fluid grouting.Two slip casting oil cylinders controlling on same mortar grouting pump alternately inject and take out slurry, and the mortar in mortar pipeline is injected continuously; Meanwhile PLC injects to move to mortar and analyzes, and then control accelerating admixture pump and the synchronous operation of mortar grouting pump, make the mixed proportion of mortar and accelerating admixture stable, greatly reduce the phenomenons such as plugging in slip casting process and incomplete mixing, improved the injection effect of biliquid slurry.Grouting operation person can open slip casting purging system, and grouting pipeline is carried out to high pressure water washing, and the slurries that stick in channel wall are rinsed well, prevents the pipeline blockage causing because of slurries solidification-stack.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the control principle schematic diagram of control module.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of dual-fluid synchronous slip casting control system, include pressure sensor 8, flow transmitter 7, control module (PLC), for detection of mortar grouting pump (by slip casting oil cylinder 41, slip casting oil cylinder 42 formations) Injection Signal and two approach switchs 5 taking out slurry signal, described pressure sensor 8 is arranged on mortar exit, flow transmitter 7 is arranged on mortar exit, stroke sensor shown in Fig. 2 is arranged on shield machine thrust oil cylinder, in order to calculate fltting speed, be used in slip casting master-control room control system showing for grouting operation personnel with reference to.Two described approach switchs 5 are separately positioned on front portion and the afterbody of slip casting oil cylinder, the signal input part of the signal output part connection control unit of the signal output part of the signal output part of described pressure sensor 8, two approach switchs 5 and flow transmitter 7, described control module connects accelerating admixture pump 2, mortar grouting pump, control accelerating admixture, mortar mixed proportion, 1 is accelerating admixture tank, and 3 is mortar stirring tank.After two fluid grouting starts, PLC is by the detection to approach switch, judgement is when the position of the first two slip casting oil cylinder 41,42, and then control taking out of two slip casting oil cylinders 41,42 and starch action and slip casting action, make two oil cylinders remain one when slip casting is moved another one taking out slurry action, and then the mortar in grouting pipeline is injected continuously; Then PLC utilizes the mortar flow of flow rate of grouting sensor 7 feedbacks and the mortar of slip casting master-control room set-up of control system, with accelerating admixture, ratio is set, and calculates the accelerating admixture injection rate needing, and then regulates accelerating admixture pump 2, controls the mixed proportion of accelerating admixture and mortar.
As shown in Figure 2, described control module is connected with local control box, and described control module is also communicated by letter with master-control room control system.Local control box and master-control room control system are two grouting operation interfaces, place: master-control room operation interface and local operation interface.Wherein, master-control room operation interface adopts high configuration touch-screen industrial computer, and operation screen is attractive in appearance flexibly, and virtual component can provide a large amount of headspaces for the system reform likely occurring.Meanwhile, be provided with local control box near mortar grouting pump, this control box has button, switch and digital indicator, and each control element is conventional components and parts, easily keeps in repair and purchases.Interface controlled by master-control room and the local interface of controlling has equal operational rights, can be switched at once another operation interface and operate when one of them operation interface breaks down, and can not have influence on the slip casting work of shield structure.The utility model is provided with automatic mode and manual mode in PLC: 1. automatic mode, and under this pattern, shield machine comprehensively compares according to the parameters of slip casting and sensor feedback information, controls filling system and automatically injects; 2. manual mode, under this pattern, slip casting operator can independently be selected injection length, injection rate and injection phase.
As shown in Figure 1, also include fluid injection pipeline cleaning system in the utility model, fluid injection pipeline cleaning system carries out segmented cleaning, is divided into leading portion cleaning and back segment and cleans two parts, improves developing result.Water inlet pipe 10 in fluid injection pipeline cleaning system connects biliquid drain pipe by reversal valve 9, then by leading portion mortar pipeline, connects return pipe 11; Mortar grouting delivery side of pump connects back segment mortar pipeline, on back segment mortar pipeline, arranges and is connected with water valve 6, and water inlet connects return pipe 11 by water valve 6, back segment mortar pipeline.After Cementer completes, grouting operation hand can be opened slip casting purging system, and grouting pipeline is carried out to high pressure water washing, and the slurries that stick in channel wall are rinsed well, prevents the pipeline blockage causing because of slurries solidification-stack.
The utility model adopts PLC as control core, utilizes PLC computing feature at a high speed, and system feedback data and shield structure running status are comprehensively judged.By pressure sensor 8 and flow transmitter 7 are set in filling system, monitor in real time flow rate of grouting and slip casting effect.Utilize the logical operation function that PLC is powerful, two slip casting oil cylinders 41,42 of controlling on same mortar grouting pump alternately inject and take out slurry, and the mortar in mortar pipeline is injected continuously; Meanwhile PLC injects to move to mortar and analyzes, and then controls accelerating admixture pump 2 and the synchronous operation of mortar grouting pump, makes the mixed proportion of mortar and accelerating admixture stable, has improved greatly the injection effect of biliquid slurry.In biliquid slurry injection process, inject the control method of incipient stage enforcement mortar and accelerating admixture simultaneous implantation, when injection stops, first system stops the injection of accelerating admixture, and then time delay stops the injection of mortar.This control mode can be first be rinsed the biliquid slurry in pipeline in advance with mortar, for the clean water in later stage, clean and lay the first stone so that grouting pipeline is cleaned cleaner.
