Description

Technical Field

[0001] This invention relates to the field of seawater desalination technology in thermal power generation, and in particular to a construction method for a stacked filter structure. Background Technology

[0002] Seawater desalination is a common freshwater supply system for coastal thermal power plants. However, due to the often limited land available at coastal power plants, existing filter structures typically separate the clear water tank and V-shaped filter, occupying a large area. Furthermore, this separation results in longer process piping and higher costs. Additionally, while some filter structures employ a stacked design, the clear water tank and V-shaped filter cannot be constructed simultaneously; the clear water tank must be built first, followed by the V-shaped filter on top, leading to lower construction efficiency and potential project delays. Summary of the Invention

[0003] The purpose of this invention is to provide a construction method for a stacked filter structure, which saves the land area required for the filter structure, shortens the length of process pipelines, reduces production costs, and allows the clear water tank and V-shaped filter to be constructed simultaneously and assembled after construction, thereby improving construction efficiency.

[0004] To achieve the above objectives, the present invention provides a construction method for a stacked filter structure, comprising the following steps:

[0005] S1. Excavate and construct a clear water tank, and at the same time fix a first track on the ground next to the clear water tank. Set a lifting component on the first track. The lifting component can slide along the trajectory of the first track. Prefabricate a V-shaped filter tank above the lifting component.

[0006] S2. The clear water tank is provided with a first reserved steel bar that protrudes from the upper end of the clear water tank. After the construction of the clear water tank is completed, a second track is set above the clear water tank. The ends of the second track and the first track are spliced ​​together and kept flush. The lifting component can slide along the first track into the second track.

[0007] S3. The bottom of the V-shaped filter is provided with a second reserved steel bar located inside the V-shaped filter. A connecting sleeve is coaxially provided on the outside of the second reserved steel bar. After the V-shaped filter is prefabricated, the lifting component supports the V-shaped filter and moves the V-shaped filter to the top of the clear water tank under the drive of the external traction device, so that the first reserved steel bar and the second reserved steel bar are coaxially arranged.

[0008] S4. The lifting assembly drives the V-shaped filter to move vertically downward, and the upper end of the first reserved steel bar is inserted into the connecting sleeve to place the V-shaped filter on the clear water tank.

[0009] S5. Remove the first track, the second track, and the lifting assembly, and grout the V-shaped filter and the clear water tank together.

[0010] Furthermore, in step S1, before fixing the first track, the ground next to the clear water pool is reinforced.

[0011] Furthermore, the lifting assembly includes a hydraulic jack and rollers, the rollers being engaged in the grooves of the first track.

[0012] Furthermore, the bottom of the V-shaped filter tank is provided with a first support surface and a second support surface from top to bottom. The output end of the lifting component abuts against the first support surface, and the second support surface contacts the upper surface of the clear water tank.

[0013] Furthermore, the height difference between the first support surface and the second support surface is greater than the sum of the heights between the lifting assembly and the second track.

[0014] Furthermore, the traction device is a winch.

[0015] Furthermore, the number of the first orbitals is at least two.

[0016] Furthermore, connecting stirrups are provided between the first reserved steel bars and between the second reserved steel bars.

[0017] Compared with the prior art, the construction method of the stacked filter structure of this invention has the following advantages: the clear water tank and the V-shaped filter can be constructed simultaneously. After the construction is completed, the V-shaped filter is installed above the clear water tank by moving the lifting component along the first track and the second track, realizing the stacked arrangement. The method is simple and easy to implement, improves construction efficiency, shortens the length of process pipelines, reduces the land area, and reduces production costs.

[0028] like Figure 1 As shown in the figure, a construction method for a stacked filter structure according to a preferred embodiment of the present invention is used to arrange the separately set clear water tank 1 and V-shaped filter 4 in a stacked manner. Simultaneously, the clear water tank 1 and V-shaped filter 4 can be constructed at the same time, improving the construction efficiency of the stacked filter structure, saving land, shortening the length of process pipelines, and reducing production costs. Its specific structure is as follows: Figure 1 As shown, the filter structure includes a clear water tank 1 and a V-shaped filter 4 stacked vertically. The clear water tank 1 has a first reserved steel bar 11 with its upper end protruding from the tank. The V-shaped filter 4 has a second reserved steel bar 41, corresponding in position and the same number as the first reserved steel bar 11. A connecting sleeve 42 is fitted over the second reserved steel bar 41, with the upper end of the first reserved steel bar 11 located inside the connecting sleeve 42. A grouting zone is provided between the upper end of the clear water tank 1 and the lower end of the V-shaped filter 4 to fix the clear water tank 1 and the V-shaped filter 4. The specific construction steps are as follows:

[0029] S1. Excavation and construction of Clear Water Pool 1, see reference. Figure 2 , Figure 3 Meanwhile, a first track 2 is fixedly installed on the ground next to the clear water tank 1, and a lifting component 3 is installed on the first track. The lifting component 3 can slide along the trajectory of the first track 2, and a V-shaped filter tank 4 is prefabricated above the lifting component 3.

[0030] S2. The clear water tank 1 is provided with a first reserved steel bar 11 that protrudes from the upper end face of the clear water tank 1. After the construction of the clear water tank 1 is completed, a second track 5 is set above the clear water tank 1. The ends of the second track 5 and the first track 2 are spliced ​​together and kept flush. The lifting component 3 can slide along the first track 2 into the second track 5.

[0031] S3. The bottom of the V-shaped filter 4 is provided with a second reserved steel bar 41 located inside the V-shaped filter 4. A connecting sleeve 42 is coaxially provided outside the second reserved steel bar 41. After the V-shaped filter 4 is prefabricated, the lifting component 3 supports the V-shaped filter 4 and moves the V-shaped filter 4 above the clear water tank 1 under the drive of the external traction device, so that the first reserved steel bar 11 and the second reserved steel bar 41 are coaxially arranged.

[0032] S4. The lifting assembly 3 drives the V-shaped filter 4 to move vertically downwards, and the upper end of the first reserved steel bar 11 is inserted into the connecting sleeve 42, placing the V-shaped filter 4 on the clear water tank 1. (Refer to...) Figure 3 ;

[0033] S5. Dismantle the first track 2, the second track 5, and the lifting assembly 3. Connect the V-shaped filter tank 4 and the clear water tank 1 by grouting to form a grouting zone 7. (See reference) Figure 5 .

[0034] Furthermore, since the first track 2 is installed on the ground to support the prefabrication of the V-shaped filter pool 4, in order to ensure the installation strength of the ground, and to avoid ground settlement when the ground strength is poor, which would affect the subsequent assembly between the V-shaped filter pool 4 and the clear water pool 1, in step S1, before setting the first track 2, the ground next to the clear water pool 1 can be reinforced.

[0035] In some embodiments, to facilitate the design and installation of the lifting assembly 3, the lifting assembly 3 includes a hydraulic jack 31 and rollers 32. The rollers 32 are engaged in the grooves of the first track 2. Specifically, the bottom of the hydraulic jack 31 is provided with rollers 32, which are engaged in the grooves of the first track. The output end of the hydraulic jack 31 can abut against the bottom of the V-shaped filter tank 4. Under the action of an external traction device, the V-shaped filter tank 4 can slide along the first track 2 to the second track 5. Furthermore, to facilitate the setting of the traction device and save space, a winch is selected as the traction device in this embodiment.

[0036] Furthermore, in order to disassemble and reassemble the second track 5 and the lifting assembly 3 after the V-shaped filter 4 and the clear water tank 1 are installed, please refer to [reference needed]. Figure 6 The bottom of the V-shaped filter 4 is provided with a first support surface 400 and a second support surface 401 from top to bottom. The output end of the lifting component 3 abuts against the first support surface 400, and the second support surface 401 contacts the upper surface of the clear water tank 1. Before the V-shaped filter 4 slides along the first track 2, the lifting component 3 drives the V-shaped filter 4 to rise to a certain height. Then, the V-shaped filter 4 is above the clear water tank 1, and the first reserved steel bar 11 and the second reserved steel bar 41 are aligned. The lifting component 3 drives the V-shaped filter 4 to descend, so that the upper end of the first reserved steel bar 11 is inserted into the connecting sleeve 42, and the second support surface 401 contacts the upper surface of the clear water tank 1. At this time, the clear water tank 1 supports the V-shaped filter 4, and then the second reserved track and the lifting component 3 can be disassembled and assembled. Furthermore, the height difference between the first support surface 400 and the second support surface 401 is greater than the sum of the heights between the lifting component 3 and the second track 5, thereby facilitating the disassembly and assembly of the second track 5 and the lifting component 3. After all components are disassembled and assembled, grouting material is injected into the grouting area 7 to allow the grouting material to reach its final setting state, and the clear water tank 1 and the V-shaped filter tank 4 are connected to form a whole.

[0037] In some embodiments, to ensure stable sliding of the V-shaped filter 4 on the first track 2, the number of first tracks 2 is at least two, and the number of second tracks 5 is the same as the number of first tracks 2. Furthermore, to improve the connection strength between the first reserved reinforcing bars 11 and the connection strength between the second reserved reinforcing bars 41, connecting stirrups 6 are provided between the first reserved reinforcing bars 11 and between the second reserved reinforcing bars 41, respectively.

[0038] In summary, the present invention provides a construction method for a stacked filter structure, wherein the clear water tank 1 and the V-shaped filter 4 can be constructed simultaneously. After construction, the V-shaped filter 4 is installed above the clear water tank 1 by the lifting component 3 moving along the first track 2 and the second track 5, thereby achieving a stacked arrangement. The method is simple and easy to implement, improves construction efficiency, shortens the length of process pipelines, reduces the land area, and reduces production costs.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
