Description
Technical field
The utility model relates to construction work grouting construction field, is specially netted provisions for grouting bottom a kind of steel lining.
Background technology
In the steel lining concrete constructions such as the penstock in power station and unit draft tube elbow, concrete setting bottom steel lining can produce after shrinking and change phenomenon of coming to nothing into, usual employing pre-buried pulp boxlike grouting system, then grout injection is clearance filled closely knit by what come to nothing.There is following problem in this form of construction work: on the one hand, owing to having laid multiple tracks stiffening ring bottom ell, penstock, affect the layout of grouting system, cause the fixing difficulty of grout cell, bury difficult quality underground and produce a desired effect, in casting process, grout cell is easily shifted and damages, cause grouting pipeline Partial Blocking to be scrapped, grouting quality cannot effectively be ensured.On the other hand, pulp boxlike grouting system is point cantact pulp, and grouting scope can not bottom all standing steel lining, need the later stage to set up grout hole supplementary irrigation in steel lining face, increases construction cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide netted provisions for grouting bottom a kind of steel lining, can solve and be provided with stiffening ring bottom steel lining and be difficult to arrange that pulp boxlike grouting system and grout cell easily damage and occur the problem that blocks, expand grouting contact area, effective raising grouting quality, and bury underground conveniently, simple to operate, steady quality, with low cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Netted provisions for grouting bottom a kind of steel lining, comprise grouting supervisor and grouting arm, grouting arm is responsible for the multiple preformed holes on steel lining for crosspoint with grouting, crisscross in netted mounting arrangements, is also laid with the stack be connected with the arm that is in the milk outside it.
The described multiple preformed hole of grouting supervisor's lateral direction penetrating is close to bottom steel lining, in bending roundabout layout.
Described grouting arm longitudinally connects two adjacent preformed holes and is close to bottom steel lining and arranges.
Described grouting supervisor and grouting arm pass through U-shaped bracket support in the bottom of steel lining.
The lower concrete that described steel lining preformed hole is corresponding has cavity.
Described grouting supervisor is hard plastic tube, and grouting arm is flexible plastic tube drawing.
Described grouting supervisor cuts off through before the part grouting of preformed hole.
Close with steel closure plate before described steel lining preformed hole grouting.
The utility model has following beneficial effect:
Netted provisions for grouting bottom a kind of steel lining that the utility model provides, is close to bottom steel lining snakelike laying grouting supervisor, is communicated with grouting supervisor forms netted grouting pipeline by tube drawing grouting arm.Inject cement paste from one end of grouting supervisor, whole line arrangement regional perfusion can be made closely knit.Overcome and to be provided with stiffening ring bottom steel lining and to be difficult to arrange that pulp boxlike grouting system and grout cell easily damage and occur the problem that blocks, expand grouting contact area, ensure that grouting quality, reduce construction cost.Especially the contact grouting in Large Steel substrate portion is applicable to.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, netted provisions for grouting bottom a kind of steel lining, comprises grouting supervisor 1 and grouting arm 2, grouting arm 2 with grouting supervisor 1 with the multiple preformed holes 3 on steel lining 5 for crosspoint, crisscross in netted mounting arrangements, be also laid with the stack 4 be connected with the arm 2 that is in the milk outside it.
The multiple preformed hole 3 of described grouting supervisor 1 lateral direction penetrating is close to bottom steel lining 5, in bending roundabout layout, grouting supervisor 1 takes lateral arrangement consistent with steel lining stiffening ring arranged direction, the small sircle hole local wide of stiffening ring and steel lining joint makes grouting be responsible for 1 to pass, avoid the interference of stiffening ring by corner.
Described grouting arm 2 longitudinally connects two adjacent preformed holes 3 and is close to layout bottom steel lining 5.
As shown in Figure 2, the lower concrete of steel lining 5 preformed hole 3 correspondence has cavity 6, and cavity draws the type of scraping out before concrete initial set bottom steel lining.
Described grouting supervisor 1 is hard plastic tube, and grouting arm 2 is flexible plastic tube drawing, and grouting supervisor 1 preferably diameter is 40mm hard plastic tube, and grouting arm 2 preferably diameter is 20mm flexible plastic tube.Tube drawing diameter passes through the small sircle hole of stiffening ring and steel lining joint compared with I, avoids the interference of stiffening ring.The duct that formation extracted by tube drawing after concreting is grouting branch passageway.
As shown in Figure 3, grouting arm is drawn concrete storehouse surface part and is installed stack 4, stack 4 preferably diameter is 40mm hard plastic tube, tee junction is set with stack joint, grouting arm 2 one end is inserted in established concrete pore passage, the other end runs in tracheae tee junction, and stack is discharged by air in hole when ensureing grouting.
As shown in Figure 4, grouting supervisor 1 and grouting arm 2 are supported on the bottom of steel lining 5 by U-shaped bracket 7, the U-shaped of U-shaped bracket 7 blocks grout pipe, and support bottom is fixed on steel mesh reinforcement.
As shown in Figure 5, described grouting supervisor 1 cuts off through before the part grouting of preformed hole 3, makes grouting be responsible for 1 duct formed with grouting arm 2(tube drawing) form the netted grouting channel of right-angled intersection.
As shown in Figure 5, close with steel closure plate 8 before steel lining 5 preformed hole 3 is in the milk, supervisor 1 of being namely in the milk closes at infall (steel lining preformed hole) with grouting arm 2, ensures that whole netted grouting system is enclosed construction, steel closure plate 8 and preformed hole adopt welded closure, not spillage when ensureing to be in the milk.
Specific works process of the present utility model and operating principle are:
Implementation step: be close to steel lining bottom surface and install grouting supervisor 1 and grouting arm 2, grouting supervisor 1 and grouting arm 2 are supported on the bottom of steel lining 5 with U-shaped bracket 7, tray chamber is every 50 ㎝ pitch arrangement.Inflate and be full of in hole in concreting forward direction grouting arm 2.
Position in storehouse checks and accepts after-pouring steel lining lower concrete.
Before concrete initial set, manually the below of steel lining preformed hole 3 correspondence is drawn and scrapes out cavity, until concrete initial set after about 1 hour flexible plastic tube exhaust extract flexible pipe, form grouting arm 2 passage.Grouting supervisor 1 cut off through before the part of preformed hole 3, and clear up the foreign material in cavity, pressure wind checks the unobstructed situation of pipeline, is closed by each preformed hole on steel lining with steel closure plate 8.
Can carry out grouting works after above-mentioned work completes, during grouting, enter slurry from the inlet pipe mouth of grouting supervisor 1, grout outlet pulp, the strengthening motoring reaching design requires rear stopping.
