The invention discloses an underground pipeline dredging method. The underground pipeline dredging method is characterized in that sludge in a pipeline is gathered to a designated position through a pipeline dredging device and then removed out of the pipeline through external force. By means of the underground pipeline dredging method, the dredging effect of the pipeline can be effectively improved, the amount of sludge in the pipeline is greatly lowered, the occurrence ratio of sludge in the pipeline is controlled below 5%, smoothness of the pipeline is ensured, and drainage efficiency of an urban drainage system is improved.
Description
Technical field
The present invention relates to road maintenance field, particularly a kind of underground conduit dredging engineering method of urban road drainage system.
Background technology
In the last few years, constantly there is city waterlogging problem in various places, directly jeopardizes the safe operation in city and the people's life security, also caused huge economic loss simultaneously.And the reason that causes city waterlogging has a lot, as excessive in rainfall, Poor construction quality of terrace-bank, drainage pipe breakage etc.And in the last few years, coastal area typhoon, heavy rain happen occasionally, the rainfall in flood season goes up year by year, and original urban sewerage and drainage system standard cannot meet the draining demand of present situation.The dynamics of urban construction is increasing in addition, the required sandy soil of engineering very easily drop and are deposited on road in transit, and rinse and flow into drainage system with road surface, cause the amount of sludge increase in pipeline to cause pipeline obstruction, also can cause rainy day impeded drainage simultaneously, further aggravation city waterlogging, affects traffic unobstructed, even causes traffic paralysis.How conscientiously improving the drainage efficiency of urban discharging pipeline, reduce pipeline alluvial or stop up, guarantee that pipeline is unimpeded, ensure safety in flood season, is the effective way that solves city waterlogging.
Also undesirable for the conventional pipelines dredger dredging effect of dredging pipeline at present.As shown in Figure 1, for using conventional pipelines dredger dredging pipeline 01.Traditional pipe dredging device comprises circular baffle plate 02; Wire rope 03 one end is connected with baffle plate 02 through catch-basin 04, and the other end is connected with baffle plate 02.The operating personnel that are positioned at ground 05 move right at pipeline 01 by wire rope 03 traction baffle plate 02, promote mud to assigned address.But conventional pipelines dredger is at moving process, and the amount of sludge of baffle plate 02 lower end is greater than the amount of sludge of upper end, and need larger power to promote the closer to the mud of inner-walls of duct.Due to the disc-shaped structure feature of baffle plate 02, it is stable that baffle plate 02 cannot keep in moving process.The mud of lower floor very easily makes baffle plate 02 run-off the straight, thereby baffle plate 02 cannot promote mud and moves.As shown in Figure 2, mud 06 applied thrust that the baffle plate 02 after inclination cannot be to lower floor, cannot make it be concentrated to assigned address, removes weak effect, and labour intensity is high, inefficiency.How to improve the removing effect of pipeline sludge, reduce as much as possible pipeline alluvial or stop up, conscientiously improve the drainage efficiency of urban discharging pipeline, particularly urgent.

As shown in Figure 7, after above-mentioned steps, adopt the inwall 11 of 10 pairs of blocking pipes 12 of high-pressure washing vehicle to carry out high pressure washing, mud residual on inwall 11 is departed from.
B3, mud secondary are removed
After remaining mud departs from inwall 11, again blocking pipe 12 is drawn water, and adopt the method for machinery suction that the silt displacement of inwall 11 remnants is gone out to blocking pipe 12.
B4, pipe detection
After above-mentioned steps, adopt pipeline CCTV detection technique to detect blocking pipe 12, the dredging situation in blocking pipe 12 is taken and fed back on display screen, and can realize the inwall 11 of blocking pipe 12 is carried out to quality examination.Testing result shows, through above-mentioned steps, the mud rate in blocking pipe 12 is lower than 5%.Wherein mud rate is the percentage that the interior amount of sludge of blocking pipe 12 accounts for blocking pipe 12 capacity.
C, pipeline deblocking
As shown in Figure 8, after above-mentioned steps, first the gas of air bag 2b is emitted, deblocking is carried out in the downstream of blocking pipe 12; Again the gas of air bag 2c is emitted, deblocking is carried out in the upstream of blocking pipe 12.The selected underground pipeline 1 that solution is honored as a queen is communicated with its upstream and downstream, recovers unimpeded state.
As shown in Figure 9, pipeline drainer comprises baffle plate 742 and base 743.As different from Example 1, on baffle plate 742 without along the through hole that extends axially setting 716 of base 743.
Except above-mentioned difference, the other guide of the present embodiment is all identical with embodiment 1.Left and right in the present invention, all take Fig. 1 as reference, is the relative concept that clearly illustrates that the present invention uses.
Embodiment in the present invention, only for the present invention will be described, does not form the restriction to claim scope, and other substituting of being equal in fact that those skilled in that art can expect, all in protection domain of the present invention.
