[0014] Step 1: According to the length, width and height of the water storage emergency pool and the dilution emergency pool, excavate the earth at the construction site to form the foundation pit required for the construction of the water storage emergency pool and the dilution emergency pool;

[0015] Step 2: After the excavation of the foundation pit is completed, a layer of cement mortar protective layer is applied on the surrounding pit walls, and then the bottom of the foundation pit is compacted, and then a layer of sand and gravel cushion is laid, and a layer of concrete cushion is poured on the sand and gravel cushion;

[0016] Step 3: After the concrete cushion at the bottom of the foundation pit solidifies, lay cement slabs on the concrete cushion, fill the joints of the cement slabs with cement and smooth them, then use steel bars and cement to build pool embryos around the foundation pit, and use steel bars and cement to build isolation walls in the middle of the foundation pit to form the pool embryos of the water storage emergency pool and the dilution emergency pool. After the cement solidifies, lay a layer of cement on the bottom and wall of the pool and smooth it, and after the cement solidifies, the pool bodies of the water storage emergency pool and the dilution emergency pool are formed.

The present invention sets up a lifting mechanism, uses a gantry in the lifting mechanism to set up the lifting mechanism on the top of the water storage emergency pool and the dilution emergency pool, starts the AC asynchronous motor in the lifting mechanism, drives the slide card to slide along the direction of the slideway, and drives the connecting rod to rotate around the connecting shaft through the movement of the slide card, so that the water storage pool cover plate and the dilution pool cover plate are pulled up and opened by the connecting rod, so that personnel can enter the water storage emergency pool and the dilution emergency pool to clean the sediment;

[0022] 2. By setting up a water storage emergency pool and a dilution emergency pool, high-concentration wastewater is first passed into the water storage emergency pool for storage. When diluting the wastewater, the water pump in the pumping mechanism is started to cooperate with the water pipe to pump part of the high-concentration sewage in the water storage emergency pool into the dilution emergency pool. The water pump and the water pipe are supported and fixed by sleepers. When the high-concentration sewage enters the dilution emergency pool, low-concentration sewage or clean water is introduced into the dilution emergency pool through the water guide mechanism to dilute the high-concentration sewage. After the wastewater is diluted, the diluted sewage is discharged into the sewage treatment system through the drainage mechanism for the next step of treatment, avoiding multiple uses of one pool. The method of single pool single use is adopted to facilitate the dilution of wastewater;

By setting a filter mechanism, when the filter mechanism is corroded, pull the flexible pull ring, and the two filter frames rotate and fold around the bearing in the direction away from the flexible pull ring, so that the filter mechanism stuck in the wastewater inlet is taken out, and then the new folded filter mechanism is put into the wastewater inlet and unfolded in the wastewater inlet, and the filter mechanism is stuck inside the wastewater inlet by using the two filter frames, so as to facilitate the replacement of the filter mechanism;

[0024] 4. The present invention provides a lifting mechanism to facilitate personnel to enter the water storage emergency pool and the dilution emergency pool to clean up the sediment. By providing the water storage emergency pool and the dilution emergency pool, multiple uses of one pool are avoided. The single-pool single-use method is adopted to facilitate the dilution of wastewater. By providing a foldable filtering mechanism and an open wastewater inlet, the replacement of the filtering mechanism is facilitated. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] A construction method for an accident emergency pool, the method specifically comprising the following steps:

[0041] Step 1: According to the length, width and height dimensions of the water storage emergency pool 1 and the dilution emergency pool 2, excavation is performed at the construction site to form the foundation pit required for the construction of the water storage emergency pool 1 and the dilution emergency pool 2;

[0042] Step 2: After the excavation of the foundation pit is completed, a layer of cement mortar protective layer is applied on the surrounding pit walls, and then the bottom of the foundation pit is compacted, and then a layer of sand and gravel cushion is laid, and a layer of concrete cushion is poured on the sand and gravel cushion;

[0043] Step 3: After the concrete cushion layer at the bottom of the foundation pit solidifies, lay cement slabs on the concrete cushion layer, fill the joints of the cement slabs with cement and smooth them, then use steel bars and cement to build pool embryos around the foundation pit, and use steel bars and cement to build isolation walls in the middle of the foundation pit to form pool embryos of the water storage emergency pool 1 and the dilution emergency pool 2. After the cement solidifies, lay a layer of cement on the bottom and wall of the pool and smooth it, and after the cement solidifies, form the pool bodies of the water storage emergency pool 1 and the dilution emergency pool 2. It should be noted that during construction, the position of the wastewater inlet 4 needs to be reserved in advance, and it is also built with steel bars and cement;

[0044] Step 4: After the construction of the water storage emergency pool 1 and the dilution emergency pool 2 is completed, the sleepers 21 are installed at the corresponding positions of the water storage emergency pool 1 and the dilution emergency pool 2, and then the water pump 19 is installed on the installed sleepers 21, and then the water pipe 20 is installed at the water inlet and outlet of the water pump 19, and the installation of the pumping mechanism 8, the water guide mechanism 9 and the drainage mechanism 10 is completed;

[0045] Step 5: After the installation of the pumping mechanism 8, the water guiding mechanism 9 and the drainage mechanism 10 is completed, a mounting groove for the rotating shaft is opened on one side of the top surface of the water storage emergency pool 1, and a semi-ring with an inner diameter larger than the outer diameter of the rotating shaft is installed in the mounting groove. The water storage pool cover plate 5 with the rotating shaft installed is installed on the upper end of the water storage emergency pool 1. After the rotating shaft is inserted into the semi-ring, another semi-ring is installed on the upper end of the rotating shaft. After that, the upper end of the mounting groove is sealed with cement, and the dilution pool cover plate 6 is installed in the same way;

[0046] Step 6: After completing the installation of the water reservoir cover 5 and the dilution tank cover 6, drill holes at the top of the water reservoir cover 5 and the dilution tank cover 6 to install the sampling port 7, then set up the lifting mechanism 3 on the upper ends of the water storage emergency tank 1 and the dilution emergency tank 2, and fix and weld the connecting card 16 to the water reservoir cover 5 and the dilution tank cover 6, and finally install the filtering mechanism 11 inside the wastewater inlet 4 to complete the construction process of the entire accident emergency tank.

[0047] It should be noted that the present invention is an accident emergency pool and its construction method. When in use, high-concentration sewage is first introduced into the water storage emergency pool 1 through the wastewater inlet 4, and the larger insoluble solids in the high-concentration sewage are filtered through the filter net 23 on the filter mechanism 11 in the wastewater inlet 4, so that the larger insoluble solids in the wastewater remain on the filter mechanism 11. When the high-concentration sewage enters the water storage emergency pool 1, sampling is performed through the sampling port 7 on the top of the water storage pool cover 5, the pH value of the sewage is detected, and a flocculant is added for flocculation and precipitation.

When the high-concentration sewage enters the dilution emergency pool 2, low-concentration sewage or clean water is introduced into the dilution emergency pool 2 through the water guide mechanism 9 to dilute the high-concentration sewage. After each dilution, it is necessary to dilute it through the dilution The sampling port 7 at the top of the pool cover 6 uses a sampler to sample sewage and measure the pH value of the sewage. When the pH value of the sewage reaches the requirement, dilution is stopped, and the diluted sewage is discharged into the sewage treatment system through the drainage mechanism 10 for the next step of treatment. The insoluble solids accumulated on the filter mechanism 11 in the wastewater inlet 4 need to be manually removed. When the filter mechanism 11 is corroded, after pulling the flexible pull ring 25, the two filter frames 22 rotate and fold around the bearing 24 in the direction away from the flexible pull ring 25, so that the filter mechanism 11 stuck in the wastewater inlet 4 is taken out and then replaced. When cleaning the sediment in the water storage emergency pool 1 and the dilution emergency pool 2, start the AC asynchronous motor 15 in the lifting mechanism 3 to drive the slide card 14 to slide along the direction of the slideway 13. The movement of the slide card 14 drives the connecting rod 17 to rotate around the connecting shaft 18, so that the water storage pool cover 5 and the dilution pool cover 6 are pulled up and opened by the connecting rod 17, which is convenient for personnel to enter the water storage emergency pool 1 and the dilution emergency pool 2 to clean the sediment.
