Description

Technical Field

[0002] With the rapid development of urbanization, the number of urban population continues to increase. During its development, there are higher requirements for infrastructure. The most important problem is water supply. Water distribution walls are usually built in water supply projects.

[0003] Flocculation tanks and sedimentation tanks are commonly used water purification structures in the water supply treatment process, which use flocculation and sedimentation to remove suspended matter in the water. Flocculation tanks are often built together with sedimentation tanks, and enter the sedimentation tank from the transition zone at the end of the flocculation tank. The water distribution wall is located between the flocculation tank and the sedimentation tank. When designing the sedimentation tank, it is required that the water inlet should be as evenly distributed as possible on the water inlet section to avoid excessive turbulence of the water flow, which may cause the formed flocs to break up and be detrimental to subsequent sedimentation.

[0004] The water distribution flower wall in the existing technology is formed by pouring concrete through the support of formwork and the installation of water inlet embedded parts. However, the number of water inlet embedded parts is large, which makes accurate installation difficult. In addition, when pouring concrete, the water inlet embedded parts are prone to problems such as displacement, dislocation, and inaccurate position, which seriously affects the construction quality. When the construction error is large, it will affect the uniformity of water distribution and thus affect the sedimentation effect. Summary of the Invention

[0037] Reference Figure 1-6 The figure shows a preferred embodiment of the present invention.

[0038] The installation method of the casting model for the construction of the water-distributing flower wall includes the following construction steps:

[0039] 1) A construction site is provided between the flocculation tank and the sedimentation tank. A horizontally arranged bottom base 100 is provided at the bottom of the construction site, and longitudinally arranged side walls 200 are provided on both sides of the construction site. Multiple shaped steel frames 300 are arranged on the bottom base 100. The shaped steel frames 300 are spaced apart along the length of the bottom base 100, with casting intervals between adjacent shaped steel frames 300.

[0040] 2) Place side formwork 400 at the front and rear ends of the construction site. The two side formwork 400 will seal the front and rear ends of the pouring interval. The front and rear ends of the shaped steel frame will abut against the side formwork 400 respectively.

[0041] 3) Clamping structures 500 are arranged outside the two side templates 400 respectively. The two clamping structures 500 clamp the two side templates 400 facing each other, fixing the two side templates 400 and the multiple shaping steel frames 300 relatively as a whole to form a casting model 600.

[0042] The above-mentioned casting model installation method for the construction of water distribution flower wall uses multiple fixed steel frames 300 to shape and install the water inlet on the water distribution flower wall, and uses the clamping structure 500 to install the side templates 400 on both sides and clamp and fix them together with the multiple fixed steel frames 300 to form a casting model 600, so that the water distribution flower wall can be poured to the top in one time, ensuring that the mold will not explode when pouring concrete, thereby improving the template installation and pouring speed of the water distribution flower wall, and solving the problems of water inlet embedded parts being easily displaced, misplaced, and inaccurately positioned when pouring concrete.

[0043] In construction step 1), a recessed groove 101 is provided on the bottom seat 100 , and the top of the shaped steel frame 300 is embedded and fixed in the recessed groove 101 ; this can improve the accuracy and stability of the shaped steel frame 300 installed on the bottom seat 100 .

[0044] In this embodiment, the shaped steel frame 300 includes two shaped steel plates 301, the inner ends of the two shaped steel plates 301 are butt-jointed, the outer ends of the two shaped steel plates 301 are arranged in an opposite and inclined manner, and the two shaped steel plates 301 are bent in the horizontal direction.

[0045] Construction steps 1) The sunken groove 101 has two groove side walls 102 arranged inclined toward each other. The lower part of the shaped steel plate 301 abuts against the groove side walls 102 from the inside to the outside. The two shaped steel plates 301 are opened away from each other to form an open area.

[0046] The concave groove 101 can allow the outer ends of the two shaped steel plates 301 to be arranged in an opposite direction and tilted through the two groove side walls 102, so that the area of ​​the water inlet end face of the formed water inlet is smaller than the area of ​​its water outlet end face, so that the flow rate of the water outlet end of the water inlet is smaller than the flow rate of its water inlet end. The flow rate of the water flow gradually decreases in the process of passing through the water inlet, effectively protecting the flocs from being broken by the impact of the flow rate in the process of passing through the water inlet.

[0047] In this embodiment, in construction step 1), after the lower portion of the shaped steel plate 301 abuts against the groove side wall 102 from the inside out, a plurality of inner support bars 303 are arranged in the open area. The plurality of inner support bars 303 are arranged at intervals along the height direction of the shaped steel plate 301. The two ends of the inner support bars 303 are respectively detachably connected to the two shaped steel plates 301. The inner support bars 303 open the two shaped steel plates 301 and are arranged at a set angle.

[0048] The open areas of the two shaped steel plates 301 are supported and fixed by a plurality of inner support bars 303 to prevent the open areas of the two shaped steel plates 301 from being squeezed and deformed during the pouring of concrete, thereby preventing errors in the water inlet.

[0049] In this embodiment, the inner ends of the two shaped steel plates 301 are hingedly arranged by hinges to form a hinge position 302, and the outer ends of the two shaped steel plates 301 swing inward and outward relative to the hinge position 302;

[0050] In construction step 1), after the bottom of the shaped steel frame 300 is embedded in the recessed groove 101, the outer ends of the two shaped steel plates 301 are swung outward to the extreme position relative to the hinge position 302 until the lower part of the shaped steel plate 301 abuts against the groove side wall 102 of the recessed groove 101 from the inside out.

[0051] The water inlet end of the water inlet is formed by the hinge portion 302 between the two shaped steel plates 301, and the expansion angle of the two shaped steel plates 301 can be controlled by the hinge, thereby controlling the flow rate of the water in the water inlet.

[0052] In this embodiment, in construction step 1), after the lower portion of the shaped steel plate 301 abuts against the side wall 102 of the recessed groove 101 from the inside out, an outer support bar 304 is arranged at the pouring interval, and the two ends of the outer support bar 304 are respectively connected to the adjacent shaped steel plates 301, thereby stretching the two adjacent shaped steel plates 301 to be inclined at a set angle.

[0053] The two adjacent shaped steel plates 301 are further fixed by the external support bars 304 to prevent the open areas of the two shaped steel plates 301 from being squeezed and deformed during the concrete pouring process, thereby preventing errors in the water inlet.

[0054] In this embodiment, the clamping structure 500 includes a plurality of horizontally arranged clamping steel tubes 501, which are spaced apart along the height direction of the side template 400. The clamping steel tubes 501 have clamping end surfaces facing the side template 400, and a plurality of clamping columns 502 are protruding from the clamping end surfaces.

[0055] In construction step 3), horizontally arranged tie studs 401 are inserted into the two side formworks 400. The middle portion of the tie studs 401 passes through the casting gap and the side formworks 400. Both ends of the tie studs 401 have external sections 402 extending to the outside of the side formworks 400.

[0056] A clamping steel pipe 501 is arranged on the outside of the side formwork 400, and the external section 402 passes through the clamping steel pipe 501 to form a connecting section 403 extending to the outside of the clamping steel pipe 501, and the clamping column 502 abuts against the side formwork 400; nuts 404 are screwed into the two connecting sections 403 of the clamping steel pipe 501 respectively, so that the clamping columns 502 of the two clamping structures 500 clamp the two side formworks 400 facing each other.

[0057] The clamping structure 500 clamps the two side formworks 400 relative to each other through multiple clamping steel pipes 501 and multiple clamping columns 502, thereby increasing the uniformity of the clamping force on the two side formworks 400. The two side formworks 400 are then fixed relative to each other using the tensioning studs 401, and the multiple clamping steel pipes 501 are fixed on the two side formworks 400 to ensure that the two side formworks 400 will not explode or leak when pouring concrete.

[0058] The outer wall of the side formwork 400 has a clamping groove 405. In construction step 3), the inner end of the clamping column 502 is docked on the clamping steel pipe 501, and the outer end of the clamping column 502 is embedded in the clamping groove 405; in this way, the positioning installation between the clamping column 502 and the side formwork 400 can be increased to prevent the clamping column 502 from being offset during the concrete pouring process and causing the formwork to explode.

[0059] In this embodiment, the outer periphery of the bottom of the clamping groove 405 expands outward to form a plurality of outwardly expanding grooves 406. The plurality of outwardly expanding grooves 406 are arranged around the outer periphery of the clamping groove 405. The inner ends of the outwardly expanding grooves 406 communicate with the clamping groove 405 to form a groove opening 407. The outer ends of the outwardly expanding grooves 406 are closed and curved.

[0060] In construction step 3), an elastic layer 503 is provided at the outer end of the clamping column 502. The thickness of the elastic layer 503 is greater than the depth of the clamping groove 405. The elastic layer 503 is embedded in the clamping groove 405. As the tensioning stud 401 pulls the clamping steel pipe 501, the elastic layer 503 is compressed. The outer periphery of the elastic layer 503 is embedded in the groove opening 407 and blocks the groove opening 407. As the depth of the elastic layer 503 embedded in the outward-expanding groove 406 increases, the air in the outward-expanding groove 406 is compressed to form a high-pressure gas area, which applies lateral pressure to the side formwork 400.

[0061] The clamping column 502 pressurizes the elastic layer 503, allowing the outer periphery of the elastic layer 503 to embed toward the groove opening 407 and block the groove opening 407. As the depth of the elastic layer 503 embedded in the outward-expanding groove 406 increases, the air in the outward-expanding groove 406 is compressed to form a high-pressure air zone, making the side formwork 400 further stable and increasing the safety of the side formwork 400 during concrete pouring.

[0062] In this embodiment, the center of the bottom of the clamping groove 405 bulges outward to form a spherical protrusion 408. The center of the outer end of the clamping column 502 is provided with a concave spherical groove 504. The elastic layer 503 covers the outer end of the clamping column 502 and fills the spherical groove 504.

[0063] The elastic layer 503 has a docking surface disposed toward the outer end of the clamping column 502. The docking surface has a docking area 505 in the middle thereof. The docking surface has a vacant area 506 formed around the docking area 505. The docking area 505 is fixedly docked with the center of the spherical groove 504, and the vacant area 506 is movably disposed at the outer end of the clamping column 502.

[0064] In construction step 3), as the tensioning stud 401 pulls the clamped steel pipe 501 , the spherical protrusion 408 is embedded in the spherical groove 504 , and the elastic layer 503 is squeezed, deformed, and embedded in the outward-expanding groove 406 .

[0065] The clamping groove 405 allows the elastic layer 503 to fill the spherical groove 504 through the spherical protrusion 408, and increases the directional deformation of the outer periphery of the elastic layer 503 when the clamping column 502 applies pressure toward the elastic layer 503, so that the outer periphery of the elastic layer 503 is embedded toward the groove opening 407 and blocks the groove opening 407. As the depth of the elastic layer 503 embedded in the outward-expanding groove 406 increases, the air in the outward-expanding groove 406 is compressed to form a high-pressure gas area.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
