Potential energy end pipeline paste body filling method includes the following steps：
Step 1, the lower end for making filling pipe 25 are corresponding with an offset 27 to be filled；When the tunnel inclination angle of the offset 27 to be filled
When more than or equal to 8 °, first the lower outlet of offset 27 to be filled is blocked tightly, is then gone out on offset 27 to be filled with filling pipe 25
The mixture of the slurry and spoil is directly perfused in mouth, and until the mixture fills solid top plate, i.e., the mixture fills
Solid rear and tunnel upper surface contact；When this wait fill offset 27 tunnel inclination angle be less than 8 ° when, first by the offset 27 to be filled
Lower outlet blocks tightly, and the lower end of filling pipe 25 is made to stretch to the lower outlet of the offset 27 to be filled, and then uses the side of retrusive
Formula (also being understood as moving up the mode of the lower end of filling pipe 25) in offset to be filled 27 the perfusion slurry and spoil it is mixed
Object is closed, until the mixture is fills up to the upper outlet of offset 27 to be filled, then the upper outlet is blocked tightly, i.e., is filled in the mixture
Be filled to reduces the ratio of spoil when filling 27 upper outlet of offset, improves the mobility of mixture, selects pipeline high position filling method (i.e.
The upper outlet that the lower end of filling pipe 25 is placed in offset 27 to be filled fills) so that the top rate that connects in tunnel is reached 100%, tunnel
Full Ratio reaches 95% or more.
Step 2 makes the lower end of filling pipe 25 offset 27 to be filled next outward move, and step 1 is repeated, until completing institute
Need to be filled the filling of offset 27, i.e., as shown in figure 4, from right to left one by one fill offset 27 to be filled, until completing all
The filling of offset 27 to be filled.
By above-mentioned introduction it is found that working face air return way replaces spoil rubber conveyer using pipeline, filling is improved
Efficiency reduces the input of equipment and the use of personnel, eliminates equipment power consumption, eliminates the unsafe condition of object is brought one
Serial unsafe acts.It is filled using a pipeline high position, it is difficult to solve the problems, such as that the filling of offset upper end connects real top plate.As long as ensureing
The height difference of pipeline import and export, you can solve the problems, such as that nearly horizontal operation face uses the filling of nature potential energy.
The above, only specific embodiments of the present invention, the range that cannot be implemented with its restriction invention, so it is equivalent
The displacement of component, or according to equivalent variations made by scope of patent protection of the present invention and modification, should all still fall within what this patent was covered
Scope.In addition, between technical characteristic and technical characteristic in the present invention, between technical characteristic and technical solution, technical solution with
Use can be freely combined between technical solution.
