Detailed Description
Taking a certain engineering of construction as an example:
according to the design and distribution of the engineering pipe well risers, the construction of the risers is divided into three construction sections of a low zone, a middle zone and a high zone according to the number of building layers, the construction sections of the low zone are arranged from 3 underground layers to 16 underground layers, and the construction sections of the middle zone are arranged from 17 underground layers to 32 underground layers, and 33 layers to 46 layers are used as the construction sections of the high zone.
All the tube well vertical tubes are placed at the corresponding tube well of the first floor through transportation, the construction sequence is that the construction is carried out in turn from a high area to a low area by a 'flip-chip method', and the hoisting equipment mainly comprises tools such as an electric hoist, a manual hoist and a steel wire rope.
As shown in fig. 1 and 2, a method for installing and constructing a riser of an ultra-high-rise tubular well by a "flip-chip method" comprises the following specific steps.
S100, dividing the construction sections into a low zone, a middle zone and a high zone according to the number of the building layers;
s200, transporting the tube well vertical tube to the corresponding tube well of the first floor, installing a main hoist at the highest floor of the low floor, and installing an auxiliary hoist at the top plate of the tube well of 1 floor, wherein the construction sequence is that the construction is carried out from the high floor to the low floor in sequence;
s300, lifting and hoisting a first section of pipeline at the first-layer pipe well by using a main hoisting block positioned at the top plate of the highest-layer pipe well in a low region;
s400, after the first section of pipeline is lifted, lifting a vertical second section of pipeline by using an auxiliary hoist at the top plate of the 1-layer pipe well;
s500, adjusting the positioning of the first section of pipeline and the second section of pipeline, ensuring that the two sections of pipeline are vertical and butt-jointed, welding the pipelines, and lifting the whole pipeline after the two sections of pipeline are firmly welded. Then hoisting a third section of vertical pipe by using an auxiliary hoist, and sequentially repeating the steps to perform welding and hoisting until the connection of the whole vertical pipe is finished;
s600, connecting pipelines of other vertical pipes in the high area, lifting the vertical pipes in the high area one by one to an installation position after the connection construction of all the vertical pipes in the high area is finished, and fixing the vertical pipe supports in the high area until all the vertical pipes in the high area are constructed.
S700, repeating the steps S200 and S600, and constructing the vertical pipes of the construction sections of the middle area and the low area in sequence.
The use effect is as follows:
1) by adopting the construction process of the tube well vertical tube 'flip-chip method', the construction quality of the vertical tube is greatly improved, the verticality of the vertical tube is ensured to be within the standard allowable range, namely less than 5L per thousand, the welding alignment straightness between pipelines is within 1/100, the whole process is not more than 10 mm, the welding appearance is smooth, and no adverse phenomena such as welding beading exist.
2) Ensure the safety of the construction of the vertical pipe of the pipe well
The pipeline construction working face is fixed, and a series of work such as welding, connection and the like is only carried out at the pipe well of the two-layer floor, so that the occurrence of safety accidents of personnel operation is greatly avoided.
The pipeline hoisting adopts a construction sequence of a 'flip-chip method', so that the potential safety hazard of horizontal transportation of each layer of the pipeline is greatly avoided, the horizontal transportation of the pipeline is only arranged at the first layer, the transportation is safe, the vertical transportation of the pipeline is only limited in a construction pipe well, the influence surface is small, and the safety is ensured.
The distance of pipeline vertical hoisting is short, because of adopting the construction of "flip-chip method", the distance of hoisting the riser perpendicularly at every turn is only the distance of a pipeline, the risk that the greatly reduced pipeline dropped, even take place to drop, its perpendicular distance is also only one deck height, can not cause very big danger.
After finishing the work at every turn on duty at the same day, can transfer whole riser perpendicularly to first floor pipe well department platform on, the hoist and mount calabash no longer bears the riser pulling force, and the pipeline is attached to on the pipe well wall, need not personnel and guard, ensures pipe well riser safety, and the riser is transferred apart from weak point, only is the one deck height, and construction convenience pulls up it again on the second day and continues the construction, improves pipe well riser safety greatly.
3) Greatly shorten the construction time of the tube well vertical tube, improve the working efficiency of workers, and compared the traditional construction method with the 'normal installation method': the 'flip-chip method' shortens the time of 25-35 days compared with the traditional construction time with the same workload.
4) The comprehensive economic benefits are far more than the following: the construction method not only greatly improves the construction quality, improves the construction progress and reduces the safety cost, but also is advanced, and the social benefit is far greater than the economic benefit.
