Description
Technical field
The utility model belongs to the municipal engineering field, relates to the unearthed device of pipe jacking tunnelling machine, especially a kind of earth pressure balance push pipe muddy water device that is unearthed.
Background technology
Domestic municipal engineering generally adopt earth pressure balanced pipe jacking tunnelling machine as the mechanical type push pipe; Its unearthed mode mainly contains two kinds: 1, in concrete plug, lay track and extend to the push-bench slag-tapping system always; Special-purpose unearthed dolly being installed in orbit and the bucket that is unearthed, is pipe jacking tunnelling machine slag-tapping system end opening above the bucket that is unearthed.In the push pipe process when development machine rotates; Because there is certain thrust (leaning on 200 tons of jack of 4-8 platform for promoting mainly) at the push pipe rear; When reaching certain numerical value in the push-bench soil pressure cabin, the slag-tapping system entry into service is transported to the soil in the soil pressure cabin in the bucket that is unearthed through this system; Then, sling the bucket that is unearthed by ground crane or gantry crane and pour into the position of regulation; 2, lean on hoist engine to pull out in concrete pipe going out navy barrow, this is the at present domestic a kind of unearthed mode of leaning on the mechanical type push pipe to adopt.
The shortcoming of above-mentioned two kinds of unearthed modes is: 1, utilization rate of equipment and installations is low; Because after the bucket that is unearthed was filled, this equipment must quit work, and adopted circular concrete plug in the pipeline mostly; Can not lay two-way track again; So need the regular hour (distance that goes out the release of navy barrow and time that pushes and push pipe is directly proportional) from going out the navy barrow release and pushing, so inefficiency, working strength of workers is big; 2, have hidden danger, because multiple electric motors is arranged in the push-bench, all power lines and illuminating line and inevitably have a certain amount of water and mud (causing because water and mud are spilt by underground water and dolly) in the concrete pipe in concrete pipe and push-bench; 3, labor productivity is low.The workman is 6-10 minute (60-80m) the go-cart time of making a round trip in concrete pipe, in 6-10 minute the supporting equipment (like Hydraulic Station, jack, crane etc.) of promising push-bench all quit work and prepare for next link; 4, go out the cost height of indigenous equipment and utilization rate is low, like straddle truck, crane, track, dolly, hoist engine etc.; 5, construction cost is high.Mainly be to realize continuous jacking, continuous excavation, construction speed is slow, and operating expenses is higher.
Summary of the invention
The purpose of the utility model just is to overcome the weak point that exists in the above-mentioned technology, and a kind of unearthed device of earth pressure balance push pipe muddy water that can realize continuous jacking, continuous excavation is provided.
The utility model solves its technical problem and takes following technical scheme:
A kind of earth pressure balance push pipe muddy water device that is unearthed; Be tightly connected with the dregs efferent duct employing of development machine; It is characterized in that: constitute by unearthed crust of the device, speed-reducing cycloidal motor, stirring rod and helical blade; Level is installed speed-reducing cycloidal motor in the crust of the device that is unearthed, and on the motor shaft of speed-reducing cycloidal motor, installs stirring rod and helical blade successively from motor drive direction, and this stirring rod axially is uniformly distributed with on motor shaft and installs; On the unearthed crust of the device of corresponding helical blade position, be fixed with a tube connector, this tube connector is communicated with the dregs efferent duct of development machine; On the unearthed crust of the device of corresponding stirring rod position, be communicated with a water inlet pipe, on the unearthed crust of the device below the speed-reducing cycloidal motor, connect a muddy water outlet.
And, on motor shaft, be uniformly distributed with and install five groups of stirring rod.
And unearthed crust of the device is installed on the connection support of concrete pipe at development machine place.
And, on the device that is unearthed, also install a pressure alarm additional.
The advantage and the beneficial effect of the utility model are:
1, this unearthed device is made up of the stirring rod of helical blade, pulverizing, servo-actuated correction etc.; Machine is provided with feed pump and output slush pump outward; Outside the workspace, handle slurry transportation; Having given full play to the potential of earth pressure balanced pipe jacking tunnelling machine equipment, can realize continuous jacking continuous excavation, is a kind of unearthed device of muddy water of automation.
2, safe and reliable, the environmental protection of this unearthed device can prevent workman's existing potential safety hazard of on push pipe is along the line, walking about, the liberation labour productive forces; Improved operating efficiency; Minimum 10 people of former unearthed mode per tour use that per tour only needs 1 people to get final product behind this equipment, have improved operating efficiency 100%-150%; Practiced thrift the energy of 30%-40%, energy conservation.
3, this unearthed device has reduced equipment cost, and can save crane, straddle truck, go out navy barrow, ancillary service such as the bucket that is unearthed, and easy to maintenance, cost is lower.
Description of drawings
Fig. 1 relates to the structural representation of the development machine of the utility model;
Fig. 2 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
A kind of earth pressure balance push pipe muddy water device that is unearthed is applied on the earth pressure balanced pipe jacking tunnelling machine, adopts with the dregs efferent duct of development machine to be tightly connected; Mud or soil that development machine is produced are discharged through the muddy water that this device becomes automation; Referring to Fig. 1, constitute by cutterhead 1, correction oil cylinder 2, cutter plate driver motor 3, oil gear 4 and dregs efferent duct 5, cutter plate driver motor-driven cutterhead rotates; The correction oil cylinder is corrected the skew problem of development machine; The dregs efferent duct is exported dregs through spiral way, more than is prior art, repeats no more at this.
The innovative point of the utility model is:
