Compared with the prior art, the grouting device for the long-distance curved top pipe in the cable tunnel has the advantages of being good in grouting effect, capable of carrying out grout injection and grout supplement simultaneously, and the like.
Description
Technical field
The utility model relates to the power cable tunnel technical field, especially relates to a kind of cable tunnel middle and long distance curve push pipe grouting device.
Background technology
Along with the needs of urban construction and development, pipe jacking construction technique has more and more widely application prospect and the space that can improve based on the raising of material technology, construction machinery performance and execution control level.Generally, the initial jacking resistance in the jacking drag overall is only relevant with thickness of earth covering, pipe diameter etc., can think constant.In a lot of pipe-jacking project projects, especially in the long-distance pipe jacking project, owing to not can be good at using the mud drag reduction technology to control the jacking resistance, occurred that upper pipe working well allows the bearing capacity deficiency and displacement or distortion, tube coupling are cracked because of overload, frequently enable relay well delays progress and cause problem such as serious environmental disturbance, even caused the engineering Failure cases also to happen occasionally because top power is excessive.Actual when carrying out jacking construction, the viscosity index of considering selected mud is big, the ratio of solid suspended particle is more in the mud suspension, and the jacking between works area distance is longer, and synchronous grouting and mend slurry when satisfying jacking needs a kind of grouting device that meets the demands of design.
Summary of the invention
But the purpose of this utility model is exactly the cable tunnel middle and long distance curve push pipe grouting device that provides the good synchronous grouting of a kind of slip casting effect for the defective that overcomes above-mentioned prior art existence and mend slurry.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of cable tunnel middle and long distance curve push pipe grouting device, this device is connected with pipe jacking tunnelling machine, this device comprises main mud jacking pumping plant, relaying slip casting station, ground base pump station and two-way pipeline, described main mud jacking pumping plant, relaying slip casting station are connected by the two-way pipeline successively with the ground base pump station, and described main mud jacking pumping plant is connected with pipe jacking tunnelling machine.
Described main mud jacking pumping plant comprises a hydraulic grouting pump and slurry-storing box that is connected.
Described relaying slip casting station comprises two hydraulic grouting pump and a slurry-storing box, and described two hydraulic grouting pump all are connected with slurry-storing box.
