Sheath 540.
In the optinal plan of the present embodiment, water-repellent paint is provided between waterproof roll 530 and concrete cushion 510.
In the optinal plan of the present embodiment, microdilatancy water-tight concrete is filled in drainage well 500.
Specifically, when installing drainage well shut-in well casing, first by excavation of foundation pit to designed elevation, with drainage well 500 it is
The heart excavates downwards, the exposed 100mm of tube body 100 (100 overhead height of tube body is more than 520 top 100mm of water-proof concrete layer) control
The height of drainage well shut-in well casing, the fixed tube body 100 of casting concrete cushion 510.At this time by the sealing of 100 outer wall bottom of tube body
In 400 Transducers Embedded in Concrete bed course 510 of ring, and vibration compacting, it completes to shunt in a well to drainage well 500 using the seal ring 400 of bottom outer
First of waterproof in portion.
After concrete cushion 510 is constructed, brushing water-repellent paint (water-repellent paint uses on-fixed pitch), and it is 1.4*
The additional waterproof course (being laid with using waterproof roll 530) of 1.4m, then paste waterproof roll 530, it is desirable that waterproof roll 530 turns over
150mm (waterproof roll 530 is bonded in 100 outer wall of tube body).Waterproof roll 530 has been constructed, construction waterproof coiled material protective layer 540
(waterproof roll protective layer 540 uses concrete cover), utilizes water-repellent paint, waterproof roll 530 and waterproof roll protective layer
540 complete the second waterproof of drainage well shut-in well jacket exterior.
After waterproof roll protective layer 540 is constructed, 520 reinforcing bar of water-proof concrete layer is bound, is poured water-proof concrete layer 520,
520 underplate concrete once-cast of water-proof concrete layer, does not stay post-cast strip and construction joint, and reduction brings dry to other subsequent constructions
It disturbs.Underplate concrete once-cast, it is ensured that underplate concrete construction quality, meanwhile, the seal ring 400 on 100 upper layer of tube body
It is cast in water-proof concrete layer 520, using the seal ring 400 on 100 upper layer of tube body, completes the of drainage well shut-in well jacket exterior
Three waterproofs.
Then, after pit earthwork backfill, shut-in well construction is carried out, underground water in well is drained, uses the impervious coagulation of microdilatancy rapidly
Soil (microdilatancy water-tight concrete use the impervious C40 concrete of microdilatancy P8) slam drainage well 500 is to designed elevation, and away from dredging
(sealing plate 300 and tube body 100 are fully welded) closing well is fully welded with 5mm thickness sealing plate 300 (using steel plate) at 500 well head 10cm of dry-well
Mouthful, complete first of waterproof inside drainage well 500.
After welding careful sealing plate 300 by designed elevation inside drainage well 500, one layer is closed with sealant 200 (leak stopping king),
Thickness of encapsulation is 100mm, completes the second waterproof inside drainage well 500.
After the completion of sealant 200 (leak stopping king) closing, the exposed 100mm steel pipe of excision tube body 100, then sealed with 5mm thickness
Plate 300 (using steel plate) is fully welded in 100 inside of tube body, completes 500 inside third road waterproof of drainage well using upper layer steel plate for sealing water.
Finally construction screed-coat is hidden by 500 occluding member of drainage well.
To sum up, drainage well shut-in well each three waterproof measure in casing inner side and outer side, shut-in well effect are good.And shut-in well construction is dry
Disturb it is small, do not influence other processes construction, improve site operation working efficiency.
