[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.

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

[0041] Reference Figure 1-5 The figure shows a preferred embodiment of the present invention.

[0042] The installation method of the fixed formwork for the construction of the water-splash wall includes the following construction steps:

[0043] 1) There is a construction site between the flocculation tank and the sedimentation tank. The bottom of the construction site has a wall base 100, and both sides of the construction site have side walls 200;

[0044] A plurality of shaped steel frames 300 are installed on the wall base 100. The shaped steel frames 300 are arranged at intervals along the length of the wall base 100, and pouring intervals for pouring concrete are formed between adjacent shaped steel frames 300. The bottom of the shaped steel frames 300 is fixed to the wall base 100, and the top of the shaped steel frames 300 extends upward.

[0045] 2) Fixing and arranging the tops of the multiple shaped steel frames 300;

[0046] 3) Along the length direction of the wall base 100 , the shaping steel frame 300 abutting against the side wall 200 is fixedly connected to the side wall 200 ; a plurality of shaping steel frames 300 in a fixed state form a shaping template 400 .

[0047] The above-mentioned method for installing the fixed formwork for the construction of the 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 fixed formwork 400 to fix them together, so that the concrete can be poured to the top at one time to form a water distribution flower wall, ensuring that the formwork will not burst when pouring concrete, improving the formwork installation and pouring speed of the water distribution flower wall, and solving the problems of displacement, dislocation, and inaccurate positioning of the water inlet embedded parts when pouring concrete.

[0048] In construction step 1), a downwardly concave embedding groove 101 is formed on the top of the wall base 100, and the bottom of the shaped steel frame 300 is embedded and fixed in the embedding groove 101; this can improve the accuracy and stability of the shaped steel frame 300 installed on the wall base 100.

[0049] 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 hinged to form a hinge position 302. The outer ends of the two shaped steel plates 301 are arranged with the hinge position 302 as the swing center, and are arranged in a direction away from each other. The two shaped steel plates 301 are bent in the horizontal direction.

[0050] Construction step 2) After the two shaped steel plates 301 of the shaped steel frame 300 are swung away from each other and tilted at a set angle, the tops of the multiple shaped steel frames 300 are fixedly arranged.

[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, the embedded groove 101 has two groove side walls 102 arranged inclined toward each other. In construction step 2), the outer ends of the two shaped steel plates 301 are swung outward relative to the hinge position 302 until the lower part of the shaped steel plate 301 abuts against the groove side wall 102 from the inside to the outside, and the two shaped steel plates 301 are opened away from each other to form an open area.

[0053] The embedded 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.

[0054] In construction step 3), the shaped steel plate 301 on the side wall against which the shaped steel frame 300 abuts is the side steel plate 303. The side wall 200 is provided with a protruding stud 304. The side steel plate 303 is provided with a through hole. The stud 304 passes through the through hole. A nut is connected to the stud 304. The nut presses against the side steel plate 303 to fix the side steel plate 303 relatively to the side wall 200. In this way, the end forming arrangement of the water distribution flower wall can be solved, and the phenomena of mold explosion or concrete leakage at the end of the water distribution flower wall during the concrete pouring process can be avoided.

[0055] In this embodiment, in construction step 2), after the lower portion of the shaped steel plate 301 abuts against the groove sidewall 102 from the inside out, a plurality of inner support bars 306 are arranged in the open area;

[0056] Multiple inner support bars 306 are arranged at intervals along the height direction of the shaped steel plate 301. The two ends of the inner support bars 306 are detachably connected to the two shaped steel plates 301 respectively. The inner support bars 306 support the two shaped steel plates 301 and are arranged at a set angle.

[0057] The open areas of the two shaped steel plates 301 are supported and fixed by a plurality of inner support bars 306 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.

[0058] In this embodiment, an internal connection hole 305 is provided on the shaped steel plate 301. In construction step 2), the two ends of the internal support bar 306 are moved through the internal connection hole 305 and then bent so that the ends of the internal support bar 306 can be detachably connected to the shaped steel plate 301.

[0059] In order to facilitate disassembly, a hinge and an inner support bar 306 are fixed together. Later, the bent section of the inner support bar 306 can be removed from the inner connection hole 305 to easily remove the shaped steel plates 301 on both sides, thereby increasing the disassembly speed.

[0060] In this embodiment, in construction step 2), after arranging multiple inner support bars 306 in the open area and opening the two shaped steel plates 301 to tilt at a set angle, outer support bars 307 are arranged in the pouring interval;

[0061] The outer support bar 307 is arranged between adjacent shaped steel frames 300, and both ends of the outer support bar 307 are detachably connected to the shaped steel plates 301 of the adjacent shaped steel frames 300, so as to stretch the two adjacent shaped steel plates 301 and arrange them at a set angle.

[0062] The two adjacent shaped steel plates 301 are further fixed by the external support bars 307 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.

[0063] In this embodiment, an external connection hole 308 is provided on the shaped steel plate 301. The external connection hole 308 is arranged between the hinge position 302 and the internal connection hole 305. In this way, the external connection hole 308 facilitates the installation and fixation of the shaped steel plate 301 by the external support bar 307. The external connection hole 308 and the internal connection hole 305 are arranged in an upper and lower staggered manner, thereby increasing the uniform positioning and fixation of the shaped steel plate 301 by the internal support bar 306 and the external support bar 307.

[0064] The outer support bar 307 includes two outer connecting bars 309 and an adjustment tube 310 disposed between the two outer connecting bars 309. The outer ends of the outer connecting bars 309 form a connecting section 311, and the inner ends of the outer connecting bars 309 form a docking section 312. The docking section 312 is provided with threads. The docking sections 312 of the two outer connecting bars 309 are arranged facing each other. The docking sections 312 are movably inserted into the ends of the adjustment tube 310 and are threadedly connected to the adjustment tube 310.

[0065] In construction step 2), after the connecting section 311 passes through the external connecting hole 308, it is arranged in a bent manner. By rotating the adjusting cylinder 310, the distance between the two external connecting strips 309 is shortened or increased during the process of threaded rotation of the adjusting cylinder 310 relative to the two docking sections 312, thereby adjusting the inclination angle between the two adjacent shaped steel plates 301.

[0066] After the outer support bar 307 passes through the outer connection hole 308 through the connecting section 311, it is bent and arranged to facilitate installation and fixation; the outer connecting bar 309 is threadedly connected to the adjustment tube 310 through the docking section 312 to facilitate adjustment of the overall length of the outer support bar 307.

[0067] In this embodiment, a strip-shaped cavity 313 is provided in the adjustment cylinder 310. The strip-shaped cavity 313 runs through both ends of the adjustment cylinder 310 in a transverse direction. Threaded ports are formed at both ends of the strip-shaped cavity 313.

[0068] In construction step 2), the docking section 312 is inserted into the strip-shaped cavity 313 through the threaded port, and the docking section 312 is threadedly connected to the threaded port;

[0069] An elastic column 314 is provided in the middle of the strip cavity 313. The middle portion of the elastic column 314 is fixed to the middle portion of the strip cavity 313. Both ends of the elastic column 314 are freely movable to form a free section. The outer periphery of the free section abuts against the inner wall of the strip cavity 313.

[0070] A guide hole is provided in the free section, which passes through the outer end of the free section to form an outer end opening 315; the docking section 312 has an inner section 316 that penetrates into the strip-shaped cavity 313, and the inner section 316 has a guide section 317 that is inserted into the guide hole;

[0071] The outer circumference of the inner section 316 expands outward to form an outer expansion ring 318. The outer expansion ring 318 is arranged around the circumference of the inner section 316. A plurality of protrusions 319 are protruded from the outer expansion ring 318. The plurality of protrusions 319 are arranged at intervals along the circumference of the outer expansion ring 318, and the plurality of protrusions 319 press against the ends of the elastic pillars 314.

[0072] In construction step 2), when the adjustment cylinder 310 is rotated to reduce the distance between the two outer connecting bars 309, the guide section 317 moves toward the elastic column 314, pressing the elastic column 314 to compress and deform, and the outer expansion ring 318 simultaneously presses the elastic column 314 to deform;

[0073] In construction step 2), when the adjustment cylinder 310 is rotated to increase the distance between the two outer connecting bars 309, the guide section 317 moves away from the elastic column 314, and the outer expansion ring 318 moves away from the elastic column 314 synchronously, and the elastic column 314 recovers its deformation.

[0074] The adjusting cylinder 310 can increase the stability of the inner section 316 of the docking section 312 when it extends into the strip-shaped cavity 313 through the elastic column 314, and increase the tension between the two docking sections 312, thereby preventing the inner section 316 of the docking section 312 from tilting or deviating during movement.

[0075] The free section increases the connection with the inner section 316 through the guide hole, thereby increasing the tension between the elastic column 314 and the docking section 312; the outer expansion ring 318 and the protruding block 319 are used to protect the compression deformation of the elastic column 314 to prevent the end of the elastic column 314 from being disconnected from the inner section 316.

[0076] 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.
