Abstract
The invention discloses an inner sleeve blocking method for leakage of a small-diameter concrete drainage pipeline. The method includes the following steps that first, a leakage well segment is judged out with a segmentation flow measurement method; second, a double-face conical iron bucket dredging device is sleeved with a rope to move back and forth to clean up impurities in the pipeline; third, in an upstream well segment inspection well of the pipeline to be handled, air is supplied into a pipe network continuously through an air blower, and the upstream pipeline is blocked; fourth, an inner sleeve is installed in the pipeline to be handled; fifth, the inner sleeve and the pipeline are blocked in the connection position of the inspection well, and mortar is injected between the inner sleeve and the pipeline for blocking. According to the method, the inner sleeve is additionally arranged in the leakage pipe segment, after the pipeline end is sealed, positions between the inner sleeve and the pipeline are grouted, so that a circular grouting ring is added to the inner side of the leakage pipe segment, and then the pipe leakage prevention effect is achieved. The method has the advantages of being simple in whole work procedure operation, short in construction period, low in cost and the like.

2) adopt two-sided taper metal bucket dredger to put rope back and forth the foreign material in pipeline, deposit cleaning to be rinsed well: first manufacture two-sided taper metal bucket dredger, described two-sided taper metal bucket dredger is made up of sleeve and rope, external diameter 10 ~ the 12cm less of internal diameter of the pipeline of described sleeve, sleeve two ends sealing and tapered, the two ends of sleeve connect a rope respectively; Two-sided taper metal bucket dredger is put into pipeline by upstream manhole, the rope of sleeve one end is placed on upstream manhole, the rope of the sleeve other end flow in the manhole of downstream with water in pipeline, or by threader, the rope of the sleeve other end is delivered to downstream manhole; Then in upstream and downstream manhole, pull sleeve by rope, the mud deposited in pipeline, foreign material are pushed in manhole, finally pick up with clear fishing combined tool and transport;
3) in the upstream well section manhole of pending pipeline, uninterruptedly blow in pipe network with blast fan, manually enter in manhole and carry out shutoff to upstream line, the ponding after shutoff in well adopts in the manhole of the downstream well section of the pending pipeline of mode suction of pump drainage;
4) in pending pipeline, install inner sleeve: inner sleeve adopts pvc pipe, the diameter 100mm less of pending pipe diameter of pvc pipe, pvc pipe adopts segmentation blanking, installs in down-hole segmentation; Progressively increase pipeline lower cushion block thickness along the every 6m of updrift side and meet drainage grade requirement; Connect by the mode that the mating connector two ends of this pvc pipe connect in well, after inner sleeve runs through pipeline, inner sleeve with the plan-position of pipeline is: upstream position inner sleeve top exterior walls is near duct bottom position, and downstream position inner sleeve top exterior walls is near duct bottom position;
5) inner sleeve and pipeline carry out shutoff at manhole link position place, and upstream shutoff mouth arranges grouting mouth, and downstream shutoff mouth sets out pore, and the space between inner sleeve and pipeline adopts the mode pouring into mortar to carry out shutoff after shutoff mouth intensity reaches requirement.
As a preferred embodiment of the present invention, in step 2) in, for pipeline that is dry, blocking, first with giant flushing pipe repeatedly, then dredge with two-sided taper metal bucket dredger.
As another kind of preferred version of the present invention, in step 2) in, after finding out the upstream and downstream of every bar drainage pipe, first desilting dredging from drain header road, the branch pipe(tube) that then cleaning blocking is serious is finally all the other branch pipe(tube)s.
Beneficial effect of the present invention: the present invention increases the inner wall form of light-wall pipe as inner sleeve of a minor diameter in the pipeline section of seepage, using the outer wall template of the pipeline section of original seepage as inner sleeve, after Seal treatment is carried out to pipe head, grouting treatment is carried out between two templates, make it increase a circular grouting ring in the insides of pipes of seepage, reach the effect preventing pipe seepage; Both avoided repeating excavation, avoid the hidden danger brought to neighbouring resident in trip inconvenience and safety, whole process operations is simple, short construction period, and the advantage such as at the bottom of cost, has broad application prospects.
