The operating principle is as follows:

the construction of the inner and outer double-layer reinforced concrete fire pool is that some quality and safety guarantee measures are additionally arranged on the basis of original common wall, beam and plate concrete pouring, so that the construction quality, safety specification and requirements are guaranteed to be met while the double-layer wall is constructed, and the progress of the project is guaranteed.

The structure is optimized through the arrangement of construction organization before construction, the frame body erected by the inner wall and the outer wall is utilized to erect and reinforce wall ribs and templates on the single-sided wall body of the inner wall, the reinforcement of the inner wall body and the templates are erected, the ladder ribs and the positioning ribs are added in the wall to ensure the distance between the inner wall construction, and the water stop bolts and the inclined struts reinforce the inner wall body and other measures to ensure the progress, quality and safety of construction.

The operation flow is as follows:

the method comprises the steps of main building raft foundation upper line laying → acceptance → wall rib binding → peripheral wall formwork support, reinforcement → formwork acceptance → wall concrete pouring, maintenance → peripheral wall inner formwork dismantling (peripheral wall outer formwork and reinforcement pipe fitting reserving), bottom plate elevation line laying → bottom plate steel bar and wall rib binding, reinforcement → formwork hanging, reinforcement → bottom plate concrete pouring, maintenance → inner wall line laying, acceptance → wall rib binding → inner wall single face formwork supporting, reinforcement → formwork acceptance → wall concrete pouring, maintenance → top plate bottom plate formwork elevation → top plate bottom plate formwork supporting, reinforcement → acceptance → top plate steel bar binding → acceptance → top plate concrete pouring and maintenance.

The erection of outside support body in the outer wall not only can use when workman's ligature reinforcing bar, can be used for fixed reinforcing bar simultaneously, ensures that the reinforcing bar can not the off normal. The erected frame body can be used for closing the die plate and reinforcing the wall body. The erected frame body can be used for multiple times, and the construction efficiency and safety performance are improved. The distance between the inner row of the frame bodies and the wall is 500mm, the width between the inner row of the frame bodies and the outer row of the frame bodies is 800mm, the distance between the sweeping rods and the ground is 200mm, and the step distance between the frame bodies is 1800 mm.

Binding peripheral wall body reinforcing steel bars: according to the well-bounced wall position line, the peripheral wall steel bars are arranged according to the following ratio of 1: and 6, when the horizontal displacement is 1, the length of the vertical bending section is 6, the vertical bending section is adjusted in place, the requirement of a protective layer is met, and the peripheral wall body steel bars are ensured to be vertical, not inclined, not toppled and not displaced. When the wall body reinforcing steel bars are bound, the wall body vertical positioning ladder bars are bound firstly, the space between the vertical positioning ladder bars is 1200mm, and the arrangement is uniform.

After the outer wall ribs are bound, the frame bodies on two sides of the wall are erected tightly, the frame bodies are used for reinforcing inclined struts of the wall body reinforcing steel bars at intervals of 2 meters and with steel pipes with the length of phi 48 being 2 meters, and during reinforcement, a plurality of opposite-top steel pipes are additionally arranged above and below the wall body to prevent the wall body from deviating during pouring.

The wall template is made of 12-thick blockboard, the back balk is 40 multiplied by 90mm balk, the distance is 150mm, the main keel is composed of 2 phi 48 steel pipes and phi 14 screw rods, the distance between the upper and lower channels of the main keel is 250mm from the floor, the middle of the main keel is 500mm, the two surfaces of the main keel are clamped by the phi 14 screw rods, and the horizontal distance between the screw rods is 500 mm. In order to ensure the lateral rigidity and integrity of the wall form, the inner surface of the form is supported on the bottom plate by a movable steel pipe top support.

The support body still can effectively utilize when pouring the outer wall, has not only guaranteed personnel's safety, the construction quality of construction, has less setting up once more of support body simultaneously, has improved the efficiency of construction.

The construction of the inner wall body comprises the construction treatment of the dividing joints with the thickness of 100mm, the binding of the bottom plate and the reinforcing steel bars of the inner wall body, and the erection of the single-sided wall body template of the inner wall body. And after the outer wall concrete is cured to meet the strength requirement, completely removing all the templates on the inner side of the outer wall.

Construction treatment of a 100mm wide dividing joint in a guide wall with the height of 300 mm: before the bottom plate and the inner wall are bound by reinforcing steel bars, an extruded sheet with the thickness of 100mm is fixed on the bottom plate and between the inner wall and the outer wall by iron wires in advance.

After the bottom plate is bound, the guide wall is 300-inch high, 300-x 3 water stop steel plates are welded in the guide wall, the water stop steel plates are exposed for 100mm and 150mm, the foundation and the guide wall are poured by adopting C30p6 concrete, and the vibration is dense.

The engineering is a reinforced concrete structure and aims to ensure the construction quality of the shear wall. And a ladder rib is arranged on the shear wall with the length of more than 3 meters. The ladder bars are arranged between the two rows of reinforcing mesh of the shear wall and used for ensuring the space, the position and the protective layer of the two rows of reinforcing meshes of the shear wall, improving the rigidity of the wall body and reducing the deformation. The ladder rib replaces the main rib and the drag hook. The distance between the two main ribs is the thickness of the wall minus the thickness of 2 protective layers minus the thickness of 2 horizontal ribs (the horizontal ribs are externally arranged). The horizontal rib spacing between two main ribs of the ladder rib is equal to the horizontal rib spacing of the wall body, and the length is the thickness of the wall body. Minus 20mm at each end (e.g., 250 thick shear wall, ladder bar horizontal bar length 210 mm). And set up the steel bar spreader bar (adopting 12 steel bars) in the wall body, the length of the spreader bar is the clearance that the interior wall thickness of fire-fighting water pool adds the construction joint, and one side is on the outer wall concrete wall body, and the opposite side is fixed on the interior wall template, can guarantee its wall thickness when making the template installation.

After the wall ribs are checked and accepted, the whole wall formwork is hoisted by a tower crane, and water stop bolts are arranged at intervals of 500mm x 500mm for reinforcement. The lengthened water stop bolt needs to reinforce two walls, so the processing length of the phi 14 screw is 950 mm. And (4) arranging one section with the water stop sheet in the wall body of the fire pool, and penetrating the other end into the outer wall body for reinforcement.

Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
