Displacement to ensure installation accuracy.

The casing 23 and the bottom plate 22 are welded by a set, and the pipe is cut according to the processing drawing of the casing 23. After cutting, the casing 23 is processed by a numerically controlled end lathe to increase the contact area between the casing 23 and the bottom plate 22, making the fixing more stable. The allowable deviation of the installation position of the casing 22 shall not exceed ±3mm, and the allowable deviation of the height of the casing 22 shall not exceed ±3mm.

After the pipe frame is completed, the bottom surface of the pipe frame and the part of the casing leaking out of the bottom surface shall be derusted and painted.

3) Pipe installation

Install the pipes on the pipe rack one by one according to the BIM pipe well layout, and the positions of the pipes correspond to the positions of the pipe racks one by one. Pipelines are processed before installation. The processing flow is: pipe cutting → nozzle cleaning → beveling → alignment and straightness inspection → spot welding at the butt joint → correction of straightness → welding of pipes → inspection of weld seams and anti-corrosion .

For pipeline blanking, welds, flanges and other connecting parts should be placed in positions that are convenient for inspection and maintenance, and a location for subsequent construction on site should be reserved, and it is not suitable to be close to the wall. The opening position shall not be at the pipe weld and its edge, and the semi-finished pipe after cutting shall be marked according to the pipe group and system, as shown in Figure 4.

The assembled pipe groups are numbered, and the prefabricated modules are coded, stored and transported using the two-dimensional code technology to improve the traceability and management efficiency of the modular riser information, and ensure the orderly assembly of each prefabricated riser unit in strict accordance with the number. Add plastic plugs 7 at both ends of the pipe and at the position of the tee opening to protect the finished product, as shown in Figure 7.

The modular riser pipe group will undergo self-inspection before leaving the factory, and then report to the supervisor for acceptance inspection. Only after passing the acceptance inspection can it be allowed to leave the factory for transportation. All welds should be subjected to in-factory flaw detection tests.

During off-site transportation, the protection of finished products should be strengthened. The pipe frame of the modular combination riser should be fixed, and a protective pad should be laid under the modular combination riser pipe to avoid bumps and paint peeling during transportation.

7) Pipeline on-site hoisting

(1) The pipe group is hoisted to the unloading platform

The outside of the building is lifted by a tower crane, using the prefabricated lugs on the modular prefabricated riser pipe frame to lift, and after the ground is hoisted to the top of the telescopic unloading platform on the equipment floor of the tower, the platform truck is moved to the unloading platform at this time , Connect one end of the upside chain to the built-in lifting point of the unloading platform, and the other end to the platform truck to fix the vehicle. Release the hoisting wire rope after the modular prefabricated riser falls smoothly on the platform vehicle. Then pull the chain up, and cooperate with the transportation personnel to completely put the prefabricated pipe group into the building.

(2) Horizontal transportation in the building

After the prefabricated riser pipe group enters the building, use the reserved holes on the structural steel beams or set up I-shaped steel clamps to place the inverted chain, use the inverted chain to place the prefabricated riser on the prepared ground tank, and then use the inverted chain to place the prefabricated riser on the prepared ground tank The ground tank transports the prefabricated riser to the designated location for hoisting or the storage location on the floor to complete the storage in the building.

(3) Hoisting in the tube well

The prefabricated riser pipe group is hoisted in sections according to the equipment layer, and is hoisted downward from each equipment layer. In order to ensure the space for the prefabricated pipe group to stand vertically, the crane hoisting system is installed in the tube well on the two floors above the equipment layer. If the steel beams of the tube wells in the upper floor corresponding to the floor are not done, the prefabricated pipe group is inserted first for hoisting work, and the steel beam installation work is carried out after the prefabricated pipe group is hoisted.

Referring to Fig. 8, the used crane system 8 is composed of hard protection 81, track beam 82, driving crane 83, system lifting device 84, control system and other parts, and the hard protection 81 is the support when the whole driving crane system is lifted.

The track beam 82 is arranged under the hard protection 81, the driving crane 83 moves along the bottom of the track beam, and the hoisting device 84 of the system can be installed under the hard protection 81 by a winch. It is also installed below the hard protection 81, and is used to control the system lifting device 84 and the driving crane 83 to operate. After the whole system is lifted to the designated position by the synchronous hoist installed on the bottom of the hard protection 81, the support main beam is connected with the pre-installed corbel on the steel beam embedded part of the tube well core tube with high-strength bolts, so that the system is fixed to the core tube wall physically. After the hoisting of the components in this stage is completed, the system starts to be installed and fixed next time, and the cycle is repeated to complete the installation of the core tube well riser module tube group. The top of the hard protective frame is paved with patterned steel, and the parts close to the wall are sealed with flaps and sealing rubber, so as to achieve the purpose of safety protection.

After using the platform truck to transport the modular prefabricated riser to the designated location for hoisting at the riser pipe well, use the crane system to hoist the modular riser, control the operation of the driving beam and electric hoist, and adjust the hook to a suitable position for hoisting components. The hoisting operation process is as follows:

① There are two lifting points (about 1.5 meters away from the pipe head) for the prefabricated modular pipe group. After the prefabricated pipe group is horizontally transported to the designated lifting position on the edge of the pipe well by using the driving lifting point and the platform truck, the hooks are respectively connected to the pipe group. The two lifting points are reliably connected.

②The lifting point draws the rope at the same time to move the modular pipe group to the obliquely upward direction in the pipe well, and the driving crane is operated to move horizontally to the inside of the pipe.

③ After about 3/4 of the modularized pipe group enters the pipe well, the crane is hoisted to receive the rope, and the pipe group is slowly erected.

④ After the modular pipe group is vertically stable, move the pipe group to the in-place position by the crane, and slowly drop to stop at 1 meter from the in-place floor. The lifting workers will adjust on the in-place floor to prevent the pipe Hit the wall or steel beam, loosen the stay rope at the crane point, and the pipe group will fall vertically.
