Referring to fig. 1 to 7, the assembling method of the prefabricated assembled type pool in the present invention sequentially comprises the following steps:

s1: the L-shaped member 21 and the vertical plate member 22 are processed according to design requirements, the prefabricated member 2 is divided into two specifications of the L-shaped member 21, namely PC1 model and the vertical plate member 22, namely PC2 model, wherein the thickness of the PC1 model L-shaped member 21 is 200mm, the width is 2200mm, the side width is 2200mm, the thickness of the PC2 model vertical plate member 22 is 200mm, the width is 1200mm, and the side width is 2200mm, therefore, the height of the prefabricated water pool in the embodiment is 2400mm, so the height of the prefabricated member 2 of the L-shaped member 21 and the vertical plate member 22 is 1200 mm.

2M 24 hoisting points 6 are arranged on each L-shaped member 21, two sides of each L-shaped member are respectively 1, and 2M 24 hoisting points 6 are arranged on each vertical plate type member 22; in the process of hoisting the L-shaped member 21 and the vertical plate member 22, the hoisting point 6 is mainly used for connecting the member and a lifting hook hanger, after hoisting is finished, the hanger is screwed out from the hoisting point 6, and then bolts for connecting the upper member and the lower member are screwed. Meanwhile, 2 connections are reserved on two sides of the L-shaped and vertical plate type prefabricated components 2 along the height direction and are used for horizontally and fixedly connecting the same-layer prefabricated components 2 and installing connecting bolts 3. The bottom of the L-shaped component 21 is reserved with 2 holes, the two sides of each L-shaped component are respectively 1, and the L-shaped component is used for being fixedly connected with the lower layer of the prefabricated component 2 and installing the connecting bolts 3, and the bottom of the vertical plate type component 22 is reserved with 1 connecting hole 4, and the L-shaped component is used for being fixedly connected with the lower layer of the prefabricated component 2 and installing the connecting bolts 3.

S2: leveling and paying off on site, and determining the hoisting positions of the L-shaped component 2 and the vertical plate component 22 of the assembled water pool; the invention adopts 'inner-approximation' paying off, namely, four standard axes of each square well are arranged according to coordinates, two control piles are arranged in the directions of the longitudinal axis and the transverse axis respectively, four control axes of a building are determined by a theodolite, and the intersection points of the axes are used as control points. The worker sequentially releases the longitudinal axis and the transverse axis of the L-shaped member 21, the inner side line and the node line of the L-shaped member 21 according to the control axis and the control horizontal line, and marks the position line and the serial number of the prefabricated member 2; the axis pay-off deviation must not exceed 2 mm. However, when the paying-off of the constructor encounters continuous deviation, the adjustment from one axis in the middle of the building to two sides is considered.

S3: hoisting the L-shaped member 2 and the vertical plate type member 22, and installing the assembled water pool; because the inner diameter of the prefabricated assembled water pool in the embodiment is 4000mm multiplied by 4000mm, the outer diameter is 4400mm multiplied by 4400mm, and the height is 2400 mm; the prefabricated member is formed by hoisting and splicing 8L-shaped members 21 in 2 layers, wherein 8 PC1 types, namely 8 prefabricated members 2 on the first layer are assembled by adopting the same method after the prefabricated members 2 on the second layer are installed, the adjacent L-shaped members 21 are mechanically connected by adopting a phi 24 connecting bolt 3, and gaps between the adjacent L-shaped members 21 are filled by using assembly type special sealant.

When the size of the prefabricated assembled water pool in the embodiment is expanded to 6200mm multiplied by 6200mm as the minimum inner diameter, 6600mm multiplied by 6600mm as the minimum outer diameter and 2400mm as the minimum height, the invention needs to adopt the L-shaped member 21 and the vertical plate type member 22 to be combined and assembled so as to achieve the size standard of the combined and assembled water pool. The prefabricated assembled water pool is formed by hoisting and splicing 8L-shaped components 21 and 8 vertical plate type components 22 in 2 layers, wherein 8 PC1 models and 8 PC2 models and 8 PC1 components and a PC2 component are mechanically connected by a phi 24 connecting bolt 3, and gaps between adjacent prefabricated components 2 are filled with special prefabricated sealant.

Before hoisting, a worker buckles a hoisting chain or a chain block, a pulling rope and a steel wire rope on a hoisting point 6 of an L-shaped member 21, wherein the hoisting chain and the steel wire rope are used for fixing the L-shaped member 21 and a hoisting tool, the hoisting chain also has the function of leveling the L-shaped member 21 in the hoisting process, and the pulling rope is used for adjusting the direction and the position of the L-shaped member 21 in the hoisting process; after the first L-shaped member 21 is placed on the foundation cushion layer, the supporting end seats are installed at the embedded M24 bolts of the vertical plate type member 22 in advance, and temporary supporting frames on the front surface and the back surface of the vertical plate type member 22 are installed after positioning, so that the stability of the vertical plate member is maintained.

When hoisting the L-shaped member 2, the worker fastens the pull ropes on two sides above the L-shaped member 21 according to the measured central shaft and side line, and adjusts the direction and the position of the L-shaped member 21 by using the pull ropes in the process of hoisting and slowly falling so as to enable the L-shaped member 21 to be approximately in place. When the first layer is 3-5 cm away from the ground, a worker needs to use a level detector to perform horizontal calibration, if the first layer is not horizontal, the worker can use a lifting chain or a chain block to adjust so that the component is horizontal, and the first layer can slowly fall in place behind the component; the L-shaped component 21 on the second layer is arranged at the position with the vertical distance of about 10cm, a connecting screw rod needs to be used for aligning holes, if the L-shaped component cannot penetrate through the holes, the hand chain block for hoisting is used for leveling, and the L-shaped component can slowly fall into place when the connecting screw rod enters the holes. When the condition that the leveling cannot be achieved in the hoisting and mounting process occurs, angle steel and a gasket are used for leveling, and the installation of each layer of components can be ensured to be level and smooth.

S4: the L-shaped member 21 and the upright plate member 22 are fastened by attaching the connecting bolt 3 thereto;

s4-1: mounting the connecting bolt 3;

the connecting bolt 3 should be screwed into the pre-embedded hoisting nut on the surface of the installed prefabricated part 2 in advance before the next prefabricated part 2 is hoisted, the next prefabricated part 2 is hoisted to the position near the installation position by using a crane, and when the swinging of the members stops, when the upper L-shaped member 21 and the lower L-shaped member 21 are spaced by about 10cm, the screw rod hole alignment is carried out. The connecting bolt 3 is strictly prohibited to be forcibly penetrated in the operation process; if the hole can not be penetrated, the hoisted gourd is used for leveling, and the hole can be aligned when the connecting screw rod can align the hole. After the prefabricated part 2 is in place, the fastening of the connecting bolts 3 is started. The connecting bolt 3 is a high-strength bolt, and the connecting pairs of the high-strength bolt, the nut and the washer in the same batch are selected according to design rules; one batch of bolts, nuts and washers cannot be used in combination with other batches of bolts.

After a layer of prefabricated parts 2 is installed, a layer of filling pad 7 needs to be laid above the prefabricated parts 2 by workers to ensure the connection tightness of the prefabricated parts 2 and be used for leveling and waterproofing the prefabricated parts 2. After the filling pad 7 is laid, a worker screws the connecting bolt 3 for connecting the upper prefabricated component 2 and the lower prefabricated component 2 into the reserved hole of the L-shaped component 21, and then hoists the prefabricated component 2 on the next layer until the hoisting is finished.

S4-2: fastening the connecting bolt 3;

the fastening of the connecting bolt 3 in the present invention is divided into initial screwing and final screwing. In the initial screwing, when the number of the connecting bolts 3 is large, a part of the axial force of the bolt fastened first is consumed to overcome the deformation, and the axial force of the bolt fastened first 3 is reduced by the distribution of the axial force after the bolts 3 are fastened around the bolt. Therefore, in order to minimize the influence of the fastening bolt 3 during the fastening process, measures are taken to minimize the mutual influence, and it is specified that the fastening is performed at least twice in the high-strength bolt fastening. The first fastening is called initial screwing, and the initial screwing axial force is generally up to 50% of the standard axial force. The final tightening is the final tightening of the installed connecting bolt 3, which is called final tightening. The final axial force value is targeted at the standard axial force and should meet the design requirements. Considering creep of the high-strength connecting bolt 3 and loss of the pretensioning force at the time of final tightening, the final tightening is generally 5% to 10% of the design pretensioning force according to the test.
