Description
Technical field
The utility model relates to a kind of grouting pipeline system, specifically is a kind of improved shield machine grouting pipeline system.
Background technology
In the face of the crowded day by day present situation of China's urban traffic, the subway market of China has obtained development rapidly, increasing large-and-medium size cities have been selected to build subway and have been alleviated blocking up of city, because the advantage of subway transportation is need not enlarge existing road surface, transportation rapid and convenient and freight volume are big.But there are a large amount of buildings and complicated network of underground in large-and-medium size cities, have brought serious challenge for subway work safety.In this case, choosing a kind of safe and reliable constructing tunnel worker method is the key of engineering success or not.Compare other construction, shield method has little, the advantages such as mechanization degree is high, safety, labor strength is low, progress is fast of ground influence, so shield method becomes the first-selection of city underground constructing tunnel.
In set of tunneling construction, for shield machine can be advanced smoothly, the diameter of cutterhead generally all will exceed shield body diameter 30ram, and because the section of jurisdiction is just to release the tail shield after assembly unit is finished in the tail shield, so after the tunnel machine warp, can produce the slit of 80-90mm between stratum and the section of jurisdiction, in order to prevent after ground settlement is to above ground structure and ground settlement the tunnel to be exerted an influence, must use mud that the slit is filled, reach firm tunnel location, prevent the purpose that ground settlement produces.And the decision shield driving whether can smooth safely most important factor the grouting quality that is exactly the shield tail, its direct relation the safety of the settling amount and the face of land structure on the face of land.
In shield-tunneling construction, shield endnote slurry has synchronous grouting, slip casting in time and three kinds of methods of secondary grouting.Synchronous grouting is a shield machine in driving forward, and the grouting pump supporting by the back is injected into the shield tail to slurries simultaneously, fills the annular gap between section of jurisdiction and the soil; Slip casting in time is that there has been a large amount of clearance spaces in the shield tail, again the mode that the gap is filled after having tunneled a ring or ring of numbers; Secondary grouting is bad in the once grouting effect, and does not fill under the closely knit situation annular gap, for preventing surface settlement or duct piece float upward, fills in and carry out mending the second time slurry.
Grouting pipeline system commonly used generally is applicable to synchronous grouting and slip casting in time, and secondary grouting then will utilize the two fluid grouting pump to realize.As shown in Figure 1, the synchronous grouting pipe-line system of prior art shield machine comprises A liquid mortar filling 10, A liquid mortar is irritated 10 and is connected with two synchronous grouting house stewards 11, each synchronous grouting house steward 11 is provided with synchronous grouting house steward valve 12 and tunneling synchronous mud injecting pump 13, each tunneling synchronous mud injecting pump 13 is provided with two outlets, described two outlets are connected with two synchronous grouting pipelines 14 respectively, and each synchronous grouting pipeline 14 is provided with synchronous grouting pipe valve 15 and pressure meter 16.In shield machine when driving,, tunneling synchronous mud injecting pump 13 is irritated 10 slurries that pump from A liquid mortar and is injected annular space between tunnel duct piece and the soil layer synchronously, and slurries solidify the back just can play the effect of stablizing section of jurisdiction and stratum.
But, when grouting amount was not enough, the proportioning of for example single liquid slurry was incorrect, causes gelling time long, cause liquid slurry when the soil body runs off or dilute by underground water, need treat that the section of jurisdiction hauls out chassis and manually mix later on and make cement paste and mix by two fluid grouting pump and water glass and carry out secondary grouting.Such grouting mode is loaded down with trivial details, and it is long to mix the slurry time, waste of manpower, and promptness is relatively poor, and grouting amount can not get guaranteeing, seriously influences construction quality, thereby has increased the probability of the face of land and surface buildings sedimentation, has brought bigger potential safety hazard.
Summary of the invention
The utility model provides a kind of improved shield machine grouting pipeline system, can carry out secondary grouting in synchronous grouting, the problem of grouting amount deficiency when solving synchronous grouting, and grouting process is simple, promptness is strong.
A kind of improved shield machine grouting pipeline system, comprise that A liquid mortar is irritated and B liquid adds case, A liquid mortar is irritated and is connected with two synchronous grouting house stewards, each synchronous grouting house steward is provided with synchronous grouting house steward valve and tunneling synchronous mud injecting pump, each tunneling synchronous mud injecting pump is provided with two outlets, and described two outlets are connected with two synchronous grouting pipelines respectively; B liquid adds case and is connected with the secondary grouting house steward, the secondary grouting house steward is provided with secondary grouting house steward valve and secondary grouting pump, the secondary grouting delivery side of pump is communicated with blender, and one of them synchronous grouting pipeline is communicated with blender by ball valve, and the outlet of blender is connected with the secondary grouting pipeline.
The improved shield machine grouting pipeline of the utility model system can carry out the second pulp feeding of section of jurisdiction in synchronous grouting, mend slurry again after need not waiting the section of jurisdiction to haul out chassis, has saved plenty of time and manpower, has guaranteed the abundance of grouting amount.
