1~Fig. 2 of reference picture, a kind of pipe well well-sealing device, including body 3, bottom closure plate 5, top closure plate 6 and positioned at bottom closure plate
The blocking ring 4 for being embedded in structure sheaf 1, the bottom are provided with core pipe 7 between 5 and top closure plate 6, the outer wall of the body 3
Closure plate 5 and top closure plate 6, which are fixed on behind the inside of body 3, is divided into the inside of body 3 positioned at the lower section of bottom closure plate 5 and for being embedded in
Installation cavity on required pipe well 2, the filled cavity between bottom closure plate 5 and top closure plate 6 and the outside positioned at the top of top closure plate 6
It is filled with chamber, the filled cavity between the outside of the core pipe 7 and the inwall of body 3 in the sealer bed of material, the core pipe 7
One end close to bottom closure plate 5 is blocked by cotton layer 8, and the inside of core pipe 7 is filled with sealant.
Be further used as preferred embodiment, the sealer bed of material include close to bottom closure plate 5 double-quick cement layer and
Close to the packing layer of top closure plate 6.Packing layer is located between double-quick cement layer and top closure plate 6.
It is further used as preferred embodiment, described filler layer is concrete layer or epoxy resin layer.
It is further used as preferred embodiment, one end in the core pipe 7 close to top closure plate 6 is sealed by sealing block 9,
The sealing block 9 is welded on the closure plate 6 of top, and in the sealing externally-located chamber of block 9.
It is further used as preferred embodiment, the concrete that block 9 is fully sealed will be sealed by being filled with the external cavity
Layer.
It is further used as preferred embodiment, the sealant is concrete layer or epoxy resin layer.
It is further used as preferred embodiment, the external diameter of the blocking ring 4 is more than 1 ~ 5cm of external diameter of body 3.
The process blocked the following is the utility model：
A, before the construction of structure sheaf 1, lay body 3 and blocking ring 4, the bore of body 3 is more than 1 ~ 5cm of external diameter of pipe well 2, blocks up
The external diameter of ring 4 is more than 15 ~ 20cm of external diameter of body 3, and blocking ring 4 mainly plays water shutoff, the distance from bottom structure sheaf 1 of body 3
Bottom 0.3m, to carry out sealing closure at initial stage to this position with double-quick cement, 5cm is pushed up in the top of body 3 less than structure sheaf 1,
So that the protective layer thickness of blocking ring 4 meets design requirement.Install after body 3, protected using protector, constructing structure layer
1 waterproof, and structure reinforcing bars concrete.（Each position connects processing with body 3 by design and code requirement progress, must not influence structure matter
Amount）.Endless tube well 2 and body 3 must not be broken simultaneously.
Shut-in well is proceeded by when B, entrance shut-in well phase to be onstructed, step is as follows：
Bottom closure plate 5 is put into body 3,（Note, closure plate bottom must not be less than the bottom of body 3）Fixation is carried out, is started to core
Pipe 7 is with inserting double-quick cement, manual compaction's closure in the middle of body 3.Core pipe 7 connects aqueduct 10, so as to the water under high pressure in pipe well 2
Outflow.Double-quick cement packed height is without departing from the bottom of structure sheaf 1.It is advisable with sealing the flowing water between core pipe 7 and body 3.Seal
After middle water, high structure label slightly expanded concrete concrete is inserted in body 3, it is mixed less than the top surface of structure sheaf 1 to insert height
7 ~ 8cm of solidifying soil, to ensure plugging material upper protective layer thickness requirement.After packing layer has some strength, covered in core pipe 7
Enter to push up closure plate 6, top closure plate 6 is welded with body 3 and top closure plate 6 with core pipe 7（Solder joint full weld, it is ensured that not permeable leak）.
C, top closure plate 6 are blocked after the completion of welding to core pipe 7, and method for blocking is to remove aqueduct 10, and cotton-wool is utilized
Cotton layer 8 is constituted after in elongated reinforcing rod feeding core pipe 7, using hydraulic pressure in core pipe 7, untill core pipe 7 is without the outflow of bright water.
After the completion of cotton-wool closure, the part core pipe 7 for being higher by top closure plate 6 carries out blowing flat using burning torch, polishes, it is ensured that core pipe 7
Not higher than push up the plate face of closure plate 6.Enter for space utilization microlith microdilatancy in core pipe 7 higher than structure one-level concrete or epoxy resin
Row filling.
Using block 9 is sealed after D, filling are full, the oral area of core pipe 7 position is welded with top closure plate 6, welding standard is ne-leakage
Untill water flows out.
The top of top closure plate 6 is filled using high structure label slightly expanded concrete after the completion of E, welding, fill surface
It is equal with structural plane.Whole pipe well 2 is so completed to block.
Above is better embodiment of the present utility model is illustrated, but the invention is not limited to institute
Embodiment is stated, those of ordinary skill in the art can also make a variety of be equal on the premise of without prejudice to the utility model spirit
