Description

Technical Field

[0001] The present invention relates to the technical field of water treatment facility construction, and in particular to a prefabricated water flow direction guiding tool box. Background Art

[0002] Municipal water treatment plant construction is gradually entering a peak period across cities and regions, with increasing efforts to upgrade, renovate, and expand water treatment facilities. This involves an increasing number of connections between existing and new structures, making the construction of structural partitions and connections for pump rooms, reservoirs, and box culverts increasingly difficult. This is coupled with increasingly stringent requirements for schedules, quality, and safety. All of these factors are driving the continuous development of structural partition and connection technologies, including prefabricated flow guidance toolboxes.

[0003] Based on the current situation, if the water flow direction within the structure is to be changed, concrete partitions and joints must be constructed. These operations will inevitably result in a low or dry water level in the structure. The disadvantages of this approach are: it significantly impacts the normal operation of existing water treatment facilities, such as waterworks and sewage treatment plants, and in severe cases, can have an impact on the surrounding environment and residents' lives, causing adverse social impacts. Furthermore, construction within the structure involves confined spaces and involves toxic and hazardous operations, posing significant safety risks and numerous potential safety hazards, which are detrimental to the occupational health and safety of workers.

[0031] The following describes the specific embodiments of the present invention in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative, rather than limiting, the scope of the present invention.

[0032] See also Figures 1 to 6 A prefabricated tool box for guiding the direction of water flow is a rectangular box. The tool box includes a top plate, a bottom plate, an outer wall panel 1, a water-passing area plug-in plate 2, an inner partition wall panel 3, a construction area plug-in plate 4, a bottom anti-floating device 5 and a water-stopping measure 6.

[0033] The exterior wall panels 1 form the four sides of the toolbox. Two reserved openings 7 are horizontally defined on the lower portion of the exterior wall panels 1 on the front side of the toolbox. Water-passing slots are located at the rear of the exterior wall panels 1 on both the left and right sides of the toolbox, into which water-passing inserts 2 are inserted from top to bottom. The interior partition panels 3 are disposed within the toolbox and include left and right partition panels and front and rear partition panels. The left and right partition panels and front and rear partition panels are arranged in a T-shape. The left and right partition panels divide the interior of the toolbox into a front space and a rear space, while the front and rear partition panels divide the front space into a front left space and a front right space. The left and right partition panels are horizontally defined with two construction area slots, corresponding to the front left space and the front right space, respectively. Construction area inserts 4 are inserted from top to bottom into these construction area slots. A bottom anti-floating device 5 is provided on the inner side of the bottom panel. Water-stopping measures 6 are provided on the inner side of the edge, inside the edge, or outside the edge of the tool box.

[0034] The toolbox can be prefabricated, assembled, or assembled using a container model or a steel plate-truss system. When the steel plate-truss system is used, the toolbox also includes a rectangular frame. The main beam at the bottom of the frame is channel steel, the crossbeam at the bottom of the frame is angle steel, the corner posts at the four corners of the frame are square tubes, the top beam at the top of the frame is square steel tube, and the middle crossbeam at the top of the frame is angle steel. Welding between the frames requires continuous spot welding, and all gaps are sealed with elastic elements. Lifting devices, which can be lifting rings, are provided at each of the eight corners of the frame for lifting, positioning, and securing during construction.

[0035] The top plate is made of corrugated steel plate, the bottom plate is made of flat steel plate, the exterior wall panel 1 and interior partition panel 3 are made of steel structure and corrugated plate connected by carbon dioxide shielded arc welding, and corrugated plate is provided around the toolbox. The reserved opening area 7 is provided with an opening frame, which is made of channel steel. The frame edge seal of the opening frame is made of rubber waterstop strips to ensure waterproofing. Four tying rings are provided on the outer surface of the top plate. The four tying rings are respectively welded to the four corner columns and connected to the bottom beam and the top beam. The bottom anti-floating device 5 can be a counterweight block. The material of the counterweight block can be concrete block or steel block, or it can be anchored to the original structure with top bolts or other forms. The waterstop measure 6 can be a rubber waterstop strip, a waterstop plate or other waterstop material. The waterstop strip is fixed to the channel steel by pre-embedded nuts and bolts. The height of the water-passing area plug 2 and the construction area plug 4 are both equal to the height of the exterior wall panel 1.

[0036] One embodiment: See Figures 7 to 9The upgrading and renovation project of a municipal sewage treatment plant included the construction of a new gate well 10 and its connection to the existing box culvert 8. The new gate well 10 had plan dimensions of 6.8m × 15.2m, a bottom elevation of -0.5m, a top elevation of 6.7m, and a pool wall thickness of 0.4m. The existing box culvert 8 had plan dimensions of 2.7m × 2.7m, a bottom elevation of 0.3m, a top elevation of 3.35m, and a pool wall and top plate thickness of 0.35m. The top of the existing box culvert 8 was a high-level well 11, and the existing box culvert 8 was 1m away from the new gate well 10. The design required that the new gate well 10 be connected to the existing box culvert 8 by opening a hole in the existing box culvert 8. At the same time, a middle partition wall 12 was installed in the existing box culvert 8 to guide the water flow in the box culvert into the new gate well 10.

[0037] Combined with the above project overview, the application of this product can optimize the design scheme. The use of prefabricated water flow direction guiding toolbox can effectively improve accuracy, construction period, safety, environmental benefits and other aspects.

[0038] The implementation plan is as follows: 1. Customize and prefabricate two tool boxes in the processing workshop according to actual on-site needs;

[0039] 2. Open a hole in the top plate of the existing box culvert 8. For the specific construction location, see Figure 7 Chisel out area 9 from the top plate of the existing box culvert 8, lift up the water-passing area inserts 2 and the construction area inserts 4 of the two tool boxes, and then use the crane to lift the lifting device of the tool box and lower the two tool boxes to the designated position.

[0040] 3. Check for any abnormalities such as water leakage or overturning. After confirming that everything is normal, refer to Figures 10 to 12 , the construction area plug-in board 4 is inserted into both tool boxes;

[0041] 4. Drain the accumulated water from the front left and right spaces of each toolbox, and then drill holes in the two reserved opening areas 7 on the front side of the toolbox and proceed with the subsequent steps. After the subsequent steps are completed, lift all the construction area inserts 4 and insert them into the water-passing area inserts 2 on the adjacent sides of the two toolboxes to complete the water flow guidance work;

[0042] 5. See Figures 13 to 15 , construct the middle partition wall 12 between the adjacent sides of the two tool boxes. After the construction of the middle partition wall 12 is completed, the two tool boxes are hoisted out as a whole to complete the final work.
