Description
Technical field
The utility model relates to shield machine grouting pipeline system, and particularly a kind of cleaning is shield machine grouting pipeline system easily.
Background technology
Along with the fast development in society and city, the underground rail traffic more and more becomes the main means of alleviating the urban traffic pressure.Shield machine is being brought into play important effect as a kind of modern underground engineering construction machinery in subway construction.In shield-tunneling construction, because of the cutterhead digging diameter of shield machine greater than the section of jurisdiction external diameter, so after the shield tail is deviate from the section of jurisdiction, between the section of jurisdiction, will form the space that width is about 14cm at the soil body, as the suitable slurries of untimely injection, to cause that surrounding soil moves, and causes surface settlement, tunnel deformation, even influences the later train operation and the anti-seismic performance of liner structure in the tunnel.
The section of jurisdiction topmost mode of outside filling slip casting is a synchronous grouting.The slurries of synchronous grouting system are to stir the back from ground forced stirrer to be transported in the mortar agitator tank the shield machine reserve cover with horizontal trasportation equipment, be delivered to the intrinsic working platform of shield machine place by a tunneling synchronous mud injecting pump and two main Grouting Pipe, inject in the steel pipe that is welded on the shield tail from many branch Grouting Pipe of working platform again and flow between section of jurisdiction and country rock.Whether the centre to control slip casting saturated if being equipped with pressure sensor.Pipe-line system figure such as Fig. 1, during this system slip casting by injection slurries in single pipe is in turn between section of jurisdiction and country rock.There is following problem in this system:
1, all have the slurries in three pipelines out-of-work in each cycle, this just makes that inner-walls of duct is more and more littler, easily causes pipeline blockage;
2, Yi Bufen pipeline can't be taken cleaning apart outside the shield shell, and is narrow and small with the pipeline junction space that the shield shell is outer, takes pipe joint apart and washes the length that delays, and can't guarantee normally carrying out of next process; If the equipment fault shutdown maintenance, the remaining slurries of staying in the grouting pipeline in time do not clean or clean and thoroughly easily do not cause pipeline blockage.
3, if slurries stir insufficient pumpability deficiency that causes; Or the inaccurate slurries setting time that causes of grout coordinate ratio is too fast, and these all easily cause pipeline blockage.
After grouting pipeline stops up,, gently then cause ground settlement if untimely cleaning and continue driving makes that then the gap between section of jurisdiction outer wall and the country rock can not in time be filled, heavy then ground is caved in.If shut down cleaning, then can make soil pressure in the cutterhead face can not get guaranteeing and influence ground settlement or cause caving in; In addition, untimely because of the contact of underground and ground, make the slurries of next ring in time not use and be set in the slurry-storing box on ground, cause whole slurries to make the link paralysis, bring immeasurable loss to construction quality.
Cleaning pipeline at the plugging manufacturing mainly contains two kinds of methods at present.Method one is to weld drill bit on the thick wire rope of 10mm, is used for clearing up grouting pipeline.This method institute time-consuming is long, and when also having little time after having cleared up to clean next root pipeline, and just clear and coherent pipeline causes the outer sand and the earth that come of returning of pipe that pipeline is stopped up once more because of the pressure reduction of managing in outer and the pipe again, influences result of use.Method two is after having annotated slurries the mortar agitator tank to be cleaned up, and with grouting pump swell soil is thrown into Grouting Pipe again, prevents the obstruction of grouting pipeline.This method is cleaned slurries agitator tank length that expends time in, and easily causing construction to interrupt, and can form earth group simultaneously after the swell soil dehydration and rest in the Grouting Pipe and with pipeline blockage, do not reach the effect of mediation pipeline.
Summary of the invention
The purpose of this utility model provides a kind of cleaning shield machine grouting pipeline system easily that not only can guarantee the unimpeded of grouting pipeline but also can save time and reduce construction cost.
Described a kind of cleaning is shield machine grouting pipeline system easily, comprise the mortar agitator tank, the duplex tunneling synchronous mud injecting pump, two main Grouting Pipe and many branch Grouting Pipe, the mortar agitator tank is communicated with tunneling synchronous mud injecting pump by outlet pipe, on outlet pipe, be provided with gate valve, two main Grouting Pipe one ends are connected with two pulp ports of duplex tunneling synchronous mud injecting pump respectively, the other end is connected with many branch Grouting Pipe respectively, on main Grouting Pipe, be provided with person in charge's pneumatic operated valve, on every branch Grouting Pipe, be provided with successively and be in charge of pneumatic operated valve, pressure sensor, terminal plug valve, it is characterized in that: described grouting pipeline system also comprises a jetting machine and two high-strength water injection pipes, the water inlet end of two high-strength water injection pipes is communicated with the outlet pipe of jetting machine, the water side is communicated with two main Grouting Pipe respectively, its junction is between duplex tunneling synchronous mud injecting pump and the main line pneumatic operated valve, is respectively equipped with outlet water control valve on two high-strength water injection pipes.
Grouting Pipe had four in described minute, and per two are connected with a main Grouting Pipe.
On pressure sensor, be provided with the pressure sensor protective valve.
The beneficial effects of the utility model: set up a water injection pipe on every main grouting pipeline, the water injection pipe valve is in closed condition when the slip casting state.Open the control valve of water injecting pipeline when slip casting is finished or during pipeline blockage, the control valve on the closing presure sensor is opened the operated pneumatic valve flushing and is got final product for one time when opening jetting machine simultaneously, can clean any pipeline or many pipelines separately.Can guarantee the unimpeded of Grouting Pipe, avoid, also can reduce the construction loss simultaneously because of pipeline blockage reduces construction speed.
