Description
Technical field
This utility model belongs in field of bridge construction Construction of Deep Foundation and underground engineering deep foundation pit construction, for forming dry operating condition in guaranteeing deep basal pit, the cast of large-area bottom concrete under water need to be carried out, for this custom-designed a kind of centralized big hopper of back cover under water of the single activate switch that can rotate that is provided with to carry out concrete sealing bottom cast, belong to one back cover centralized hopper under water.It is applicable to the construction of all kinds of deep basal pit back cover under water.
Background technology
In bridge foundation construction or in underground engineering construction, it is positioned in deep water due to foundation ditch or excavation of foundation pit is relatively deep, for dry construction can be formed in guaranteeing foundation ditch, underwater concrete need to be poured in foundation ditch and carry out back cover.Owing to foundation ditch area is relatively big, bottom concrete generally requires the employing big hopper of centralized back cover and pours into a mould.
(1) traditional big hopper of underwater concrete back cover and construction method thereof:
Traditional big hopper of underwater concrete back cover uses the centralized hopper being provided with 4 activate switch devices.This kind of big hopper is made up of central authorities' storage bin hopper, activate switch device and sub-material bucket.Wherein sub-material bucket and activate switch device are 4, are separately positioned on all directions four direction, the corresponding sub-material bucket of each activate switch device.Wherein being provided with multiple feed opening (generally 3) according to field condition on sub-material bucket, each feed opening is all connected with a chute, and every chute and a little hopper connect, and little hopper and a back cover conduit connect.Feed opening uses plate to control the flow direction of concrete.
The big hopper of traditional back cover uses step as follows:
1) big for back cover centralized hopper frame it is located in the middle of back cover platform and fixes, back cover conduit, little hopper and chute are installed, making each chute and the discharging opening one_to_one corresponding on centralized sub-material bucket.
2) by 4 activate switch device Close Alls below centralized hopper, all using pinboard to block discharging opening each on sub-material bucket, leaving behind the discharging opening with first back cover conduit need not close.
3) it is manually entered in centralized storage bin hopper, gunnysack is used to be blocked by 3 activate switch devices, in order to avoid concrete enters in activate switch device, activate switch device is blocked by concrete initial set of long duration, and leaving behind needs to pour the activate switch device of side and need not block.
4) delivering concrete in storage bin hopper.
5) etc. storage bin hopper inner concrete storing enough after, open the activate switch device not have closure, concrete is in sub-material bucket, the chute little hopper of inflow.
6), when little hopper will completely struggle against, pull up annular cover plate and carry out first potting bottom application work.
7), after a conduit back cover completes, close activate switch device and the discharging opening of sub-material bucket being connected with this conduit, unplug the discharging opening being connected with next root back cover conduit.Continue delivering concrete in storage bin hopper.
8) construction of next root conduit back cover is carried out according to the order of step 5,6.
9) after etc. completing at the bottom of the first potting of side, closing this activate switch device, being manually entered the interior gunnysack of storage bin hopper etc. blocks this activate switch device, and then removing needs to pour the gunnysack in the activate switch device of side.
10) carry out the first envelope construction of other conduit according to the order of step 4 to step 9, during carry out the normal feed supplement of each conduit and pour.
11) the big hopper of back cover etc. is removed after bottom concrete completes.
(2) limitation of traditional big hopper of back cover under water:
1) in-convenience in use: traditional big hopper is provided with 4 activate switch devices, and owing to can only open an activate switch every time, other 3 activate switches must block, in order to avoid concrete enters dead for activate switch closure, causes trouble to later stage cast；And be plane bottom storage bin hopper, easily deposit concrete, and often cast a period of time will send workman to carry out labor cleaning in carrying out big hopper.
2) security risk is high: uses the big hopper of traditional back cover to carry out back cover, often seals a conduit, is required for workman and climbs to the top of big hopper and enter back cover big hopper inner bottom part and carry out clearing up and blocking activate switch device, and job safety risk is high.
3) back cover progress is slow, the back cover time is long: owing to being accomplished by carrying out operation in workman enters big hopper at interval of a period of time, and every time the activity duration longer, concrete cannot be laid in storage bin hopper in this activity duration, have a strong impact on back cover progress, cause the back cover time long.
4) back cover quality is relatively poor: owing to the bottom concrete single side of pouring amount is big under water, the general back cover time is relatively long, this proposes higher requirement to bottom concrete slow setting time and construction organization, the concrete retarding time is required to have to be larger than back cover total time, this point to be accomplished, one is the slow setting time extending concrete, but shortens the back cover time.And use traditional back cover big hopper back cover, carry out the work such as cleaning in repeatedly entering storage bin hopper due to needs workman, extend back cover total time, so can affect the quality of back cover.
5) manufacture difficulty is big, cost of manufacture is high: the big hopper of traditional back cover is provided with 4 activate switch devices, and the requirement on machining accuracy of activate switch device is higher, and difficulty of processing is relatively large, so will necessarily strengthen manufacture difficulty and the cost of manufacture of the big hopper of back cover.
6) activate switch device is easily blocked; activate switch device is caused to be difficult to open: to use the big hopper of traditional back cover to clear up and block activate switch device due to needs workman; often cause activate switch device to be difficult to open because workman's cleaning is not clean or closure is the most tight, affected greatly by workman.
