(1) Process flow
The method comprises the following steps of early investigation → traffic relief → operation in limited space for crossing the bottom → forced ventilation → gas detection → examination and approval of well descending operation → pipeline plugging → closure and drainage guide → pipeline dredging → acceptance and transfer.
Early-stage investigation: the method mainly aims to determine the pipeline dredging range, judge the pipeline clogging condition and determine the technical scheme.
Traffic fluffing: mainly aims at ensuring the safety of normal dredging construction and traffic operation.
Forced ventilation: the natural ventilation is kept, and the harm of toxic gas to operators is reduced.
And (4) gas detection, namely monitoring the content of toxic gas in the underground pipeline at regular time and ensuring construction in safety.
And (3) examining and approving the well descending operation: the strict approval system of the downhole operation is the premise of ensuring the smooth operation of the project.
Pipeline plugging: when the upstream water flow is large, brick laying and air bag double-layer plugging are needed, and the upstream and downstream of the pipe section needing dredging are plugged so as to facilitate detection.
Temporary guide and drainage: and pumping the sewage at the upstream of the construction section out of the inspection well by using a sewage pump, and discharging the sewage into a downstream pipe to ensure that the pipeline normally completes dredging.
Dredging a pipeline: the high-pressure pump that utilizes washing car 1 beats out the water under high pressure, through high-pressure hose, utilizes the nozzle to spout high-pressure water flow, and foraminiferous and can shoot a aperture that is greater than the shower nozzle diameter forward directly in this nozzle front, then utilize the water impact to impel the principle and go forward, lean on simultaneously to enlarge the drilling to the efflux of spouting to one side, the shower nozzle impels forward, silt flows out to the contact well backward with the inclined hole rivers, and the soil pick-up car carries out the soil pick-up operation simultaneously. When solid blockage exists in the pipe, the pressure of the jet flow vehicle needs to be adjusted, when continuous water jet flow continuously impacts the blockage, stable impact force is formed, and the water jet pressure for cleaning the impurities in the common pipeline is shown as the following table I (pressure for cleaning the impurities in the common pipeline).
Acceptance and transfer: and (3) adopting a CCTV (closed-circuit television) endoscopic system for detecting the interior of the pipeline without structural defects, and shooting image data of the inner wall of the lining pipe to form a report. The pipe wall should not have the functional defects of tree roots, dam roots, residual walls and the like.
