Sealing film bag, which carries out water-filling, to be made to overhaul storehouse and channel sealing, then the water drained in maintenance storehouse makes Awaiting Overhaul region in no water ring
Border, to realize the maintenance of not cutting off the water of channel；It is safe and reliable, can satisfy the Practical Project situation of long large channel, avoids
Various aspects caused by cutting off the water influence, and improve the economic and social benefits.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the A-A sectional view in Fig. 1.
Fig. 3 is the schematic perspective view that storehouse is checked in Fig. 1.
Specific embodiment
Repair method of not cutting off the water of the present invention for large channel is needed using maintenance storehouse as shown in Figs. 1-3,
It is made of steel frame and the water blocking steel plate 1 being welded on the inside of it.Above-mentioned steel frame includes multiple from channel side slopes to canal bottom side
To the door shape frame 2 being sequentially arranged, door shape frame 2 is weldingly connected with a plurality of longitudinal girder steel 3.For the stability of reinforcement structure, each
Diagonal brace 5 is welded between door shape frame 2 and the extension shape pedestal 4 of its two sides.Above-mentioned water blocking steel plate 1 is the steel plate of 20mm thickness, remaining
Steel member is all made of I-steel.The construction space requirement of repair and maintenance is carried out to meet personnel in maintenance storehouse, height is extremely
It is less 2m；The length and width for overhauling storehouse is then set according to the size of service area.Generally, the end of longitudinal girder steel 3 extends
At to horizontal canal bottom center, when maintenance storehouse is seated in left and right sides side slope respectively, comprehensive covering to canal bottom can be formed, only
A maintenance storehouse is made, by exchanging the placement location in maintenance storehouse, the maintenance to full channel can be completed, effectively reduce maintenance
Cost.When maintenance storehouse size is larger, the split type structure (overhauling storehouse in Fig. 3 to be made of four parts) being readily transported can be used.
Specifically, the water blocking steel plate 1 positioned at maintenance storehouse stitching portion forms ribs to outer folding edge, offers connecting hole on ribs, makes
Used time is spliced by bolt.
It overhauls and is welded with hoisting ring on the steel frame in storehouse, hanging device Z is facilitated to place it in channel Awaiting Overhaul region.For
Formation water-less environment, the top opening for overhauling storehouse are located at channel water level or more.In addition, water blocking steel plate 1 and canal lining connect
It is bonded with sealing film bag 6 in contacting surface, sealing film bag 6 is by high strength elastic material (such as steel fibre rubber composite material or high-strength multiple
Close rubber etc.) it is made, and be connected with water-filling mechanism, water-filling mechanism usually selects commercially available water pump.It can be with after 6 water-filling of sealing film bag
Canal lining is in close contact, and achievees the effect that sealing blocks water.Further, rubber sheet gasket 7 has been covered on the pedestal 4 of door shape frame 2,
The frictional force between steel frame and canal lining can be increased, to resist dynamic hydraulic thrust, prevent to tumble.Overhaul the steel in storehouse
Frame can also carry additionally appropriate counterweight, to reinforce stability of the maintenance storehouse in overcurrent channel.
Repair method of not cutting off the water of the present invention for large channel, includes the following steps:
The first step, according to canal cross section form and size, production maintenance storehouse；
Second step, according to channel actual conditions, selection wheeled car is hung or crawler crane is lifted storehouse is overhauled to channel Awaiting Overhaul area
Domain, except the top opening in maintenance storehouse is located at channel water level or more, other parts are respectively positioned on the water surface hereinafter, making to overhaul each side bottom in storehouse
Portion comes into full contact with channel flow surface；
Third step carries out water-filling, water-filling to sealing film bag using water pump after Awaiting Overhaul region is completely covered in confirmation maintenance storehouse
Sealing film bag afterwards can be completely attached to canal lining, form sealing stop water；At this point, shutting down water pump, and close filling valve
Door stops guaranteeing that sealing film bag is water-tight to sealing film bag water-filling；
4th step will be overhauled water body inside storehouse with immersible pump and be drained, meanwhile, clump weight is installed additional at left and right sides of maintenance storehouse, until
Anhydrous inside storehouse and maintenance storehouse monolithic stability is overhauled in the channel of overcurrent；
5th step, overhaul storehouse is stable, do not intake in the case where, dispose ladder on channel side slopes, service personnel along ladder into
Enter and overhaul storehouse, while service kit and material are put into maintenance storehouse along slope, service personnel completes channel service work and edge is climbed
Ladder recalls bank, and service kit and material are transported maintenance storehouse, guarantees foreign in maintenance storehouse；
6th step, the water-filling into maintenance storehouse, removes clump weight, discharges water to sealing film bag, this maintenance is completed in lifting maintenance storehouse
The service work in region；
7th step overhauls other Awaiting Overhaul regions according to method described in step 2 to six, until completing complete overhaul
Work.
