Description

A kind of synchronous grouting mortar vehicle for shield-tunneling construction
Technical field
The utility model is related to tunneling shield filling systems, refer in particular to a kind of synchronous grouting mortar for shield-tunneling construction Vehicle.
Background technology
In recent years, subway transportation has gradually become the important means that city solves traffic congestion, and shield method is as ground The main engineering method of iron construction, has been obtained for being more and more widely used.In municipal construction, Land-Subsidence Control is to ensure ground The factor first of face construction of structures safety, and with the expansion of subway transportation network and perfect, subway tunnel inevitably needs More constructions of structures even operated subway line is passed through under complex geological condition, this controls the stratum settlement of shield-tunneling construction More stringent requirements are proposed for technology.
The ground settlement generated in shield tunneling process is mainly caused by construction caused by Stratum Loss.(stratum Loss is to excavate soil body volume in shield-tunneling construction and build up the difference of tunnel volume), Stratum Loss, shield machine are provided with together in order to control Filling system is walked, section of jurisdiction outer void is filled to make up Stratum Loss by injecting synchronous slurries in time at shield tail rear.Upper soft During lower hard formation, risk source is crossed in order to better, synchronous grouting is taken to be filled with inert slurry both of which, it can be in time So that the sedimentation above shield body with shield tail rear is dropped in controlled range;It is carried due to the synchronous grouting system of existing shield machine Vehicle mortar jar only there are one, and inert slurry viscosity is higher, can not direct slip casting, need first to inject in mortar jar and be noted again Slurry will use mortar vehicle directly to carry out slip casting as mortar holding vessel to meet the two slip casting simultaneously.But in slip casting Cheng Zhong, can be because suction pump and slip casting stick power be inconsistent, and lead to mortar tracheal rupture or mortar pump motor damage or mortar A series of problems, such as pump case is blocked with pipeline, influences the normal slip casting process of mortar.
Invention content
In order to solve defect of the existing technology, the utility model provides a kind of synchronous grouting sand for shield-tunneling construction Vehicle is starched, which can be used for mortar holding vessel and synchronize slip casting, can't lead to slip casting tracheal rupture or blocking, will not There is the problems such as grouting pump damage.
Technical solution provided by the utility model:A kind of synchronous grouting mortar vehicle for shield-tunneling construction, including storage It starches tank and the suction pump in slurry can bottom is set, stirring blade is equipped in slurry can, it is characterised in that:It is set in slurry can There are storage bin hopper, the storage bin hopper to be placed in slurry can top, its underpart is in funnel-form, grout outlet is equipped in its bottom, in storage bin hopper Position higher than slurry can offers overflow port, and the suction pump of the slurry can bottom is connected to by jelly suction pipe with storage bin hopper, storage The grouting port of hopper is connect by Grouting Pipe with shield tunneling synchronous mud injecting pump feed inlet, and the size of grouting port and tunneling synchronous mud injecting pump Feed inlet is equal in magnitude, and the return duct for leading to slurry can is equipped at storage bin hopper overflow port.
The utility model preferably technical solution:The storage bin hopper is placed in the top of slurry can tail portion, and part is higher by storage Tank is starched, the overflow port is placed in the part that storage bin hopper is higher by slurry can.
The utility model preferably technical solution:The suction pump is placed in slurry can lower center position, is located at suction pump The stirring blade angle of both sides is opposite.
The utility model preferably technical solution:Grout outlet and overflow diameter on the storage bin hopper are 150mm.
The slip casting transport system of the utility model, battery truck is starched in vehicle transported slurry to tunnel, anti-by mortar vehicle suction pump Conveying slurries prevent grouting pump and mortar pump power inconsistent to mortar funnel again, cause mortar vehicle funnel to overflow mortar, in sand It starches and increases overflow passage on the outside of vehicle funnel, overflow passage flows back to slurry vehicle again, and mortar vehicle funnel is by itself drop height slurry Liquid is transported to grouting pump feed inlet, and slurries are transported to each Grouting Pipe by grouting pump by self-suction function.
The utility model increases a storage bin hopper in the slurry can of grouting vehicle, keeps the slurries that suction pump is extracted out directly defeated It is sent in storage bin hopper, is opened up among storage bin hopper there are two mouth, one is connect with grouting pump by feed liquid delivery pipe, and ensures The load of material mouth is consistent with the inlet amount of grouting pump, another is flowed back by return duct in slurry can, avoids because taking out Phenomena such as slip casting tracheal rupture of the inconsistent appearance of the power of stock pump and grouting pump, grouting pump damage or jam of grouting pipe, and its Slip casting effect can reach normal slip casting effect, the case where being not in that flow is small, influence slip casting.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is mortar vehicle internal structure schematic diagram;
Fig. 3 is the structural schematic diagram of the stirring blade of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.As shown in Figure 2 is a kind of for the same of shield-tunneling construction Slip casting mortar vehicle is walked, including slurry can 1 and the suction pump 2 in 1 bottom of slurry can is set, the suction pump 2 is placed in 1 bottom of slurry can Portion middle position is equipped with stirring blade 3 in slurry can 1, as shown in figure 3,3 angle of stirring blade positioned at 2 both sides of suction pump On the contrary, when stirring, agitating shaft drives stirring blade by mortar toward conveying at slurry pumping port, ensures that slurries are drained only in mortar vehicle.
