Description
Technical field
The invention belongs to cable work well fields, more particularly, to a kind of assembled cable work well and site operation
Method.
Background technique
Currently, mostly use cast-type construction method when building cable work well, the cable work well of cast-type exist with
Under disadvantage: 1) it is long in time limit, cast-type cable work well need live assembling reinforcement, live formwork, poured in place concrete, after
Phase demoulding etc., the duration is very long, and the curing age of single concrete just needs 28 days；2) costly, it is excavated from ground, binding steel
Muscle, production mold, concreting, concrete curing, form removable just need to spend more expense；3) effect on environment is big,
Municipal cable work well is often built in city, and the excavation of foundation soil unavoidably will affect urban environment, influence city image,
The construction period of cast-type cable work well generally requires one month or more time, shadow larger for urban environmental impact
Ring normal trip.
Then there are some prefabricated assembled cable active wells, but since assembly parts quantity is more, is only adopted between assembly parts
With simple splicing and bolted mode, and there are certain deviations in assembly for prefabricated components, so that between assembly parts
Rubber water-proof item cannot play good waterproof action, and underground water often penetrates into cable work well, threaten Electrical Safety
With the personal safety of maintenance personnel, in addition, the process that assembly parts excessively make assembly construct becomes complicated, these unfavorable factors
All limit the application and popularization of assembled cable work well.
Summary of the invention
Aiming at the above defects or improvement requirements of the prior art, the present invention provides a kind of assembled cable work well and now
Construction method, by key component for example plain concrete cushion layer, reinforced concrete floor, U-shaped steel reinforced concrete side plate and
The structure of reinforced concrete cover plate and the design of arrangement, obtain it is a kind of it is structurally reasonable, barrier performance is good, assembly is simple
Assembled cable work well has the advantages that short time limit, low cost, environmental perturbation are small.
To achieve the above object, according to one aspect of the present invention, a kind of assembled cable work well is proposed comprising
Plain concrete cushion layer, reinforced concrete floor, U-shaped steel reinforced concrete side plate and the reinforced concrete earth mulch set gradually from bottom to up
Plate, in which:

Assembled cable work well of the invention specifically uses following steps to carry out site operation:
Be prepared before construction: surveying setting-out excavates foundation soil, and foundation soil leveling, crane is in place, determines that element is mixed
The Hoisting Position of solidifying soil padding；
Crane is lifted plain concrete cushion layer 1 to designated position by 4 pull rings that cable wire connects plain concrete cushion layer 1,
It unloads cable wire and is installed on the pull ring of reinforced concrete floor 2 and reinforced concrete floor is lifted, by armored concrete bottom
Cable wire is unloaded after the lifting to designated position of plate 2, determines the placement position of stiffness bearer 11, wherein stiffness bearer 11 is placed in U-shaped
The midpoint on the every bottom edge of armored concrete side plate 3；First left side U-shaped steel reinforced concrete side plate is lifted in place with crane, and is protected
The position for demonstrate,proving U-shaped steel reinforced concrete side plate is correct；Lifting the right U-shaped steel reinforced concrete side plate after the same method；To U-shaped steel
After the completion of the lifting of reinforced concrete side plate, early strong concrete is poured, to fill the gap between two blocks of U-shaped steel reinforced concrete side plates
And the gap between U-shaped steel reinforced concrete side plate and reinforced concrete floor, for connecting two pieces of U-shaped reinforced concrete floors
And U-shaped steel reinforced concrete side plate and reinforced concrete floor；
After pouring completion 2 days, so that early strong concrete is reached 75% or more strength failure criterion, then mixed reinforcing bar with crane
Solidifying earth mulch plate 4 is lifted on the concrete beam chosen outside U-shaped steel reinforced concrete side plate, fills reinforced concrete with early strong concrete
Gap between earth mulch plate and armored concrete side plate is made by making early strong concrete reach 75% or more strength failure criterion
It will not make concrete cracking because of strength problem after obtaining in cover plate lid, and can shorten the construction period, improve benefit；
Foundation soil directly can be backfilled to former base hole position after populated early strong concrete, complete a cable work well
Whole constructions.
The present invention had not only given full play to the small advantage of fabricated construction short time limit, low cost, environmental perturbation, but also puted forth effort to solve dress
Problem with formula component barrier performance difference, can be applicable on a large scale.
As it will be easily appreciated by one skilled in the art that the foregoing is merely illustrative of the preferred embodiments of the present invention, not to
The limitation present invention, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should all include
Within protection scope of the present invention.
