Description
Technical field
The utility model is related to urban construction field more particularly to a kind of discarded underground piping plugging structures.
Background technology
Old subdrainage pipe network in city, since former design standard is relatively low, pipe network structure is weak, by for many years
After use, the corrosion of pipeline is very serious, and the pipeline for being unable to normal use will be discarded,.Large-scale discarded pipe is embedded in
Underground, extremely hazardous, there are the security risks such as surface collapse and the stability for influencing superstructure.In order to eliminate discarded pipe
Security risk, the utility model provide a kind of plugging structure of discarded underground piping.
Invention content
Above-mentioned in order to solve the problems, such as, the utility model aim is to propose that a kind of discarded underground piping blocks knot
Structure, the discarded underground piping plugging structure eliminate the security risk of surface collapse, and simple in structure, construction efficiency is high, convenient fast
Victory, securely and reliably.
To achieve the goals above, the utility model uses following scheme, including pipeline, the pipeline to be equipped with multiple closure
Segment pipe, the inside for blocking segment pipe left end build the first block wall by laying bricks or stones, and the interior of segment pipe right end that block builds second by laying bricks or stones
Block wall；Active well is equipped at the top of pipeline at left and right sides of the closure segment pipe；The top of second block wall is along vault
Equipped with discharge opening；It is uniformly provided with multiple slip casting through-holes from left to right at the top of the closure segment pipe；The closure segment pipe and
Mud is filled in slip casting through-hole.
Preferably, the length for blocking segment pipe is less than 20m.
Preferably, the thickness of first block wall and the second block wall is not less than 200m.
Preferably, the material on first block wall top is micro-expansion cement.
Preferably, the discharge opening is in a quarter ring.
Preferably, the number of the slip casting through-hole is four.
When construction, pipeline is first divided into multiple closure segment pipes, active well is opened at left and right sides of segment pipe blocking；Work
Personnel build the first block wall and the second block wall by laying bricks or stones through active well in block section pipe ends；It is reserved on the top of the second block wall
Discharge opening；Slip casting through-hole there are four uniformly being opened from left to right at the top of closure segment pipe；Grouting equipment is by slip casting through-hole to envelope
Stifled segment pipe carries out slip casting, until slip casting through-hole and closure segment pipe fill up；It blocks after the completion of being filled in segment pipe and stands four
By five days, mud sediment and consolidation in segment pipe are blocked, carries out second of mud filling；It is right again after the completion to block segment pipe filling
Active well carries out mud filling.
Discarded underground piping plugging structure described in the utility model eliminates the security risk of surface collapse, simple in structure,
Construction efficiency is high, convenient and efficient, securely and reliably.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of discarded underground piping plugging structure described in the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can be more
Add and be apparent from, as shown in Figure 1, the utility model uses following scheme, including pipeline, the pipeline to be equipped with multiple block sections
Pipeline 1, the inside for blocking 1 left end of segment pipe build the first block wall 5 by laying bricks or stones, it is described block 1 right end of segment pipe in build the by laying bricks or stones
Two block walls 7；It is equipped with active well 4 at the top of the pipeline for blocking 1 left and right sides of segment pipe；The top of second block wall 7
It is equipped with discharge opening 8 along vault；1 top of the closure segment pipe is uniformly provided with multiple slip casting through-holes 3 from left to right；The block section
Mud 6 is filled in pipeline 1 and slip casting through-hole 3.
The length for blocking segment pipe 1 is less than 20m.The thickness of first block wall, 5 and second block wall 7 is not less than
200m.The material on 5 top of the first block wall is micro-expansion cement.The discharge opening 8 is in a quarter ring.The slip casting is logical
The number in hole 3 is four.
When construction, pipeline is first divided into multiple closure segment pipes 1, active well 4 is opened in the left and right sides for blocking segment pipe 1；
Staff builds the first block wall 5 and the second block wall 7 by laying bricks or stones through active well 4 at 1 both ends of closure segment pipe；In the second block wall 7
Top reserve discharge opening 8；Slip casting through-hole 3 there are four uniformly being opened from left to right at 1 top of closure segment pipe；Grouting equipment passes through
Slip casting through-hole 3 carries out slip casting to blocking segment pipe 1, until slip casting through-hole 3 and closure segment pipe 1 fill up；It blocks and is filled out in segment pipe 1
After the completion of filling and four to five days are stood, blocks mud sediment and consolidation in segment pipe 1, carries out second of mud filling；Block section
Mud filling is carried out to active well again after the completion of the filling of pipeline 1.
Discarded underground piping plugging structure described in the utility model eliminates the security risk of surface collapse, simple in structure,
Construction efficiency is high, convenient and efficient, securely and reliably.
