Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is made into one
Step ground describes in detail.
A kind of small-bore sewage conduct restorative procedure, comprises the following steps:
The first step, confirmation are positioned at the position of pipe deforming rejected region to be repaired between adjacent No. 1 inspection shaft 10 and No. 2 inspection shafts 20
Put A, use horizontal directional drilling machine 40 to bore pilot hole a long way off by flat drill bit 41, sequentially pass through No. 2 inspection shafts, pipe to be repaired
Road is to No. 1 inspection shaft, and horizontal directional drilling machine starts pierce ground and enter in the middle of sewage conduct by No. 3 inspection shafts a long way off,
Described No. 3 inspection shafts and No. 2 inspection shafts are adjacent；With specific reference to Figure of description Fig. 1.
Second step, at No. 1 inspection shaft, lay down flat drill bit, change reaming bit 42, and at the reaming bit other end even
Connecing some short steel pipes 50, in a preferred embodiment of the present invention, reaming bit afterbody has the protection device preventing Study on Soil Collapse,
Its protection UR drill bit uses rotating transfer case to be attached with short steel pipes, it can be ensured that reaming bit is at rotation processing reparation pipe
During road, short steel pipes does not rotates.With specific reference to Figure of description Fig. 2, Fig. 3.
3rd step, pulled back by horizontal directional drilling machine, make pipe deforming rejected region to be repaired in the effect of reaming bit
Lower cutting extruding makes it recover former pipe shape, and short steel pipes joining with the reaming bit other end forms first inner liner support；
With specific reference to Figure of description Fig. 4.
4th step, laying down reaming bit at No. 2 inspection shafts, the drilling rod of the horizontal directional drilling machine that continues to pull back is until it is pulled away from
Ground, after the drilling rod of horizontal directional drilling machine is pulled away from ground, is filled with pilot hole；With specific reference to Figure of description Fig. 5.
5th step, the glass fibre of impregnating resin worked out flexible pipe draw in the first liner formed by short steel pipes,
Then inflation makes it be close to first liner, by tractive ultra-violet lamp, uses UV curing process, makes impregnating resin
Glass fibre establishment flexible pipe solidify to form continuous, waterproof, smooth surface, corrosion resistance are good and have the two of relatively high structural strength
Secondary liner, UV curing process uses the ultraviolet curing equipment 60 being located at No. 2 inspection shaft well heads to carry out.Glass fiber hose
It solidify to form high intensity, waterproof secondary internal lining pipe under ultra-violet lamp irradiates.This internal lining pipe smooth surface, Manning coefficient are more former
There is pipeline little, even if when internal lining pipe is slightly less than original pipe diameter, it is also possible to recover original pipeline area of passage；With specific reference to
Figure of description Fig. 6.
In the preferred embodiment, a length of 0.5m of above-mentioned short steel pipes, use two groups of steel disc symmetries even between adjacent two short steel pipes
Connecing, one of which steel disc includes two steel discs, and each steel disc uses pair of bolts to be connected with short steel pipes.
The above disclosed present pre-ferred embodiments that is only, can not limit the right model of the present invention with this certainly
Enclose, the equivalent variations therefore made according to the claims in the present invention, still belong to the scope that the present invention is contained.
