Description

Technical Field

[0001] This invention relates to the technical field of water-distribution flower walls, and more specifically, to a construction method for water-distribution flower walls. Background Technology

[0002] Water treatment is an important component of water supply engineering. Its task is to remove various harmful impurities from raw water through a combination of processes such as chemical addition, mixing reaction, coagulation, sedimentation, filtration, and disinfection, so that the water meets the water quality standards for urban living and production.

[0003] Flocculation tanks and sedimentation tanks are commonly used water purification structures in water treatment processes. They remove suspended solids from water through flocculation and sedimentation. Flocculation tanks are often built together with sedimentation tanks. At the end of the flocculation tank, the water enters the sedimentation tank through a transition zone. When designing the sedimentation tank, it is required that the water flow at the inlet be as evenly distributed as possible on the inlet section to avoid excessive water turbulence that could cause the already formed flocs to break up, which would be detrimental to subsequent sedimentation.

[0004] The commonly used structural form for the water distribution wall of the sedimentation tank in a water supply plant is a cast-in-place reinforced concrete unit. Due to the small perforation width, there are significant difficulties in the formwork erection and pouring during construction. Furthermore, it is difficult to accurately control the size and elevation of the wall openings. Large construction errors can affect the uniformity of water distribution and thus the sedimentation effect. Summary of the Invention

[0005] The purpose of this invention is to provide a construction method for water-distribution flower walls, aiming to solve the problems in the prior art where there are great difficulties in the formwork erection and pouring of water-distribution flower walls, and the difficulty in accurately controlling the opening size of the wall.

[0006] This invention is implemented as follows: the construction method for the water-distribution flower wall includes the following construction steps:

[0007] 1) There is a construction position between the flocculation tank and the sedimentation tank. The base of the wall is formed by formwork at the bottom of the construction position, and the side walls are formed by formwork on both sides of the construction position. The side walls and the wall base are an integral structure.

[0008] 2) Install multiple fixed steel frames on the wall base, and arrange the multiple fixed steel frames at intervals along the length direction of the wall base, forming a casting interval between adjacent fixed steel frames; the bottom of the fixed steel frame is fixed to the wall base, and the top of the fixed steel frame extends upward.

[0009] 3) End templates are arranged at the front and rear ends of the construction position, with the two end templates arranged facing each other at intervals, and the two end templates respectively enclose the front and rear ends of the pouring interval.

[0010] 4) Concrete is poured into the pouring interval from top to bottom. After the concrete solidifies, it forms grid bars. The shaped steel frame is located between adjacent grid bars, and a shaped interval is formed between adjacent grid bars. The shaped steel frame is placed in the shaped interval.

[0011] Concrete is poured on top of the multiple grid bars, and after the concrete solidifies, it forms a wall top beam, which is connected to the top of the multiple grid bars as a whole.

[0012] 5) Dismantle multiple of the aforementioned fixed steel frames, the fixed intervals forming a through water inlet channel, the water inlet channel being located between adjacent grid bars, and the flocculation tank being connected to the sedimentation tank through multiple water inlet channels.

[0013] Furthermore, in construction step 1), a downward-facing recessed embedding groove is formed on the top of the wall base, and in construction step 2), the bottom of the fixed steel frame is embedded and fixed in the embedding groove.

[0014] Furthermore, the shaped steel frame includes two shaped steel plates, the inner ends of the two shaped steel plates are joined together, the outer ends of the two shaped steel plates are arranged at opposite angles, and the two shaped steel plates are bent in the horizontal direction.

[0015] In construction step 2), the embedded groove has two groove sidewalls arranged in opposite directions. The lower part of the shaped steel plate abuts against the groove sidewall from the inside to the outside. The two shaped steel plates are separated from each other and open to form an open area.

[0016] Furthermore, in construction step 2), after the lower part of the shaped steel plate abuts against the side wall of the groove from the inside out, multiple inner support strips are arranged in the opening area.

[0017] Multiple inner support bars are arranged at intervals along the height direction of the shaped steel plate. The two ends of each inner support bar are detachably connected to two shaped steel plates respectively. The inner support bars open up the two shaped steel plates at a set angle.

[0018] Furthermore, the surface of the shaped steel plate is covered with a plastic film or coated with a release agent, and the inner ends of the two shaped steel plates are arranged by hinges to form a hinge position, and the outer ends of the two shaped steel plates swing inward and outward relative to the hinge position.

[0019] In construction step 2), the outer ends of the two shaped steel plates are swung outward relative to the hinge position to the limit position until the lower part of the shaped steel plate abuts against the side wall of the embedded groove from the inside out, and then multiple inner support bars are arranged in the opening area.

[0020] Furthermore, in construction step 2), after the lower part of the shaped steel plate abuts against the side wall of the embedded groove from the inside out, an outer support strip is arranged in the pouring interval. The two ends of the outer support strip are respectively connected to the adjacent shaped steel plates, so that the two adjacent shaped steel plates are spread apart and arranged at a set angle.

[0021] Furthermore, in construction step 2), the shaped steel plate abutting against the side wall is a side steel plate. A stud protrudes from the side wall, and a through hole is provided on the side steel plate. The stud passes through the through hole, and a nut is connected to the stud to fix the side steel plate against the side wall.

[0022] Furthermore, in the construction step 4), after placing the spacer bars in the pouring interval and pouring concrete into the pouring interval, multiple vibrators are inserted into the concrete. The multiple vibrators are arranged in parallel at intervals in the concrete and vibrate the concrete.

[0023] During the process of vibrating the concrete, the vibrator moves vertically up and down in the concrete at a set frequency, and the upward pulling speed of the vibrator is greater than the downward insertion speed of the vibrator.

[0024] Furthermore, the vibrating rod is provided with a plurality of hinged rods on its outer periphery, and the plurality of hinged rods are arranged at intervals around the circumference of the vibrating rod; a horizontally rotating ring is fitted on the outer periphery of the vibrating rod, and the inner end of the hinged rod is hinged to the rotating ring through a hinge shaft.

[0025] When the hinge rod swings upward to its limit position, the hinge rod is arranged perpendicular to the vibrating rod; when the hinge rod swings downward to its limit position, the hinge rod is attached to the outer periphery of the vibrating rod.

[0026] In construction step 4), when the vibrator is inserted into the concrete downwards, due to the resistance of the concrete, the multiple hinged rods swing upwards and are arranged horizontally, perpendicular to the vibrator; when the vibrator is pulled out of the concrete upwards, due to the resistance of the concrete, the multiple hinged rods swing downwards and adhere to the outer periphery of the vibrator.

[0027] In construction step 4), when the vibrator is inserted into the concrete and multiple hinged rods are inserted into the concrete, the hinged rods and the vibrator are arranged at an angle and swing back and forth. The rotating ring rotates around the outer circumference of the vibrator as the vibrator rotates.

[0028] Furthermore, in the construction step 4), during the process of pouring concrete into the pouring interval, the hose is first used to pour concrete to a set depth into the pouring interval from top to bottom, then the hose is pulled out, and a rigid pipe is inserted into the concrete from top to bottom, and concrete is poured from bottom to top until the pouring interval is filled with concrete.

[0029] The bottom of the hose has multiple branched lower tubes, which are arranged at intervals around the circumference of the hose. The upper end of each branched lower tube is connected to the bottom of the hose, and the lower end of each branched lower tube is arranged downward. A limiting ring is provided between the multiple branched lower tubes to limit the outward expansion of the multiple branched lower tubes.

[0030] In construction step 4), the concrete in the hose is poured from top to bottom through multiple branched lower pipes until the concrete in the pouring interval reaches the set depth.

[0031] The bottom of the rigid tube is provided with a plurality of curved branched upper tubes, which are arranged at intervals around the circumference of the rigid tube. The upper end of the branched upper tube is connected to the bottom of the rigid tube, and the lower end of the branched upper tube is arranged to be curved upward.

[0032] In construction step 4), the bottom of the rigid pipe is inserted into the concrete, and the lower end of the bifurcated upper pipe is submerged in the concrete. The concrete in the rigid pipe is poured from bottom to top through the lower end of the bifurcated upper pipe.

[0033] Compared with the prior art, the construction method of the water distribution flower wall provided by the present invention uses multiple fixed steel frames to fix and install the water inlet channel on the water distribution flower wall, and installs the templates on both sides, so that the grid of the water distribution flower wall can be poured to the top in one go. This ensures that phenomena such as formwork bursting will not occur when pouring concrete, improves the template installation and pouring speed of the water distribution flower wall, and solves the problems that there are great difficulties in template support and pouring during the construction of the water distribution flower wall, and that it is difficult to accurately control the opening size of the wall.

[0046] Reference Figure 1-8 The image shown is a preferred embodiment of the present invention.

[0047] The construction method for the water-retaining flower wall includes the following steps:

[0048] 1) There is a construction site between the flocculation tank and the sedimentation tank. The wall base 100 is formed by formwork construction at the bottom of the construction site, and the side walls 200 are formed by formwork construction on both sides of the construction site. The side walls 200 and the wall base 100 are an integral structure.

[0049] 2) Install multiple fixed steel frames 300 on the wall base 100. The multiple fixed steel frames 300 are arranged at intervals along the length of the wall base 100, and a casting interval is formed between adjacent fixed steel frames 300. The bottom of the fixed steel frame 300 is fixed on the wall base 100, and the top of the fixed steel frame 300 extends upward.

[0050] 3) Install end formwork 400 at the front and rear of the construction site respectively. The two end formwork 400 are arranged facing each other at intervals, and the two end formwork 400 respectively enclose the front and rear of the pouring interval.

[0051] 4) Pour concrete into the pouring interval from top to bottom. After the concrete solidifies, it forms grid bars 500. The shaped steel frame 300 is located between adjacent grid bars 500. The adjacent grid bars 500 form a shaped interval. The shaped steel frame 300 is placed in the shaped interval.

[0052] Concrete is poured on top of multiple grid bars 500. After the concrete solidifies, it forms a wall top beam 600, which is connected to the top of the multiple grid bars 500 as a whole.

[0053] 5) Remove multiple fixed steel frames 300, and form a front-to-back water inlet channel 700 with fixed intervals. The water inlet channel 700 is located between adjacent grid bars 500. The flocculation tank is connected to the sedimentation tank through multiple water inlet channels 700.

[0054] The above-mentioned construction method for the water-distribution flower wall uses multiple fixed steel frames 300 to fix and install the water inlet channel 700 on the water-distribution flower wall, and installs the end formwork 400 on both sides. This allows the grid strips 500 of the water-distribution flower wall to be poured to the top in one go, ensuring that phenomena such as formwork bursting will not occur during concrete pouring. This improves the formwork installation and pouring speed of the water-distribution flower wall, and solves the problems that there are great difficulties in both formwork erection and pouring during the construction of the water-distribution flower wall, and that it is difficult to accurately control the opening size of the wall.

[0055] In construction step 1), a downward-facing recessed embedding groove 101 is formed on the top of the wall base 100. In construction step 2), the bottom of the fixed steel frame 300 is embedded and fixed in the embedding groove 101. This can improve the accuracy and stability of the fixed steel frame 300 installed on the wall base 100.

[0056] 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 joined together, the outer ends of the two shaped steel plates 301 are arranged at opposite angles, and the two shaped steel plates 301 are bent in the horizontal direction.

[0057] Construction step 2) The embedded groove 101 has two groove sidewalls 102 arranged in opposite directions. The lower part of the shaped steel plate 301 abuts against the groove sidewall 102 from the inside to the outside. The two shaped steel plates 301 are separated from each other and open to form an open area.

[0058] The embedded groove 101 allows the outer ends of the two shaped steel plates 301 to be arranged at opposite angles through the two groove sidewalls 102, so that the area of ​​the water inlet end face of the formed water inlet channel 700 is smaller than the area of ​​its water outlet end face, so that the flow velocity at the water outlet end of the water inlet channel 700 is smaller than the flow velocity at its water inlet end. The flow velocity of the water gradually decreases as it passes through the water inlet channel 700, effectively protecting the flocs from being broken by the impact of the flow velocity as they pass through the water inlet channel 700.

[0059] In this embodiment, in construction step 2), after the lower part of the shaped steel plate 301 abuts against the side wall 102 of the groove from the inside out, multiple inner support strips 303 are arranged in the opening area.

[0060] Multiple 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 up the two shaped steel plates 301 and are arranged at a set angle.

[0061] Multiple inner support bars 303 are used to expand and fix the opening areas of the two shaped steel plates 301, so as to prevent the opening areas of the two shaped steel plates 301 from being squeezed and deformed during the concrete pouring process, which would cause errors in the water inlet channel 700.

[0062] In this embodiment, the surface of the shaped steel plate 301 is covered with a plastic film or coated with a release agent, which facilitates later removal. The inner ends of the two shaped steel plates 301 are arranged by hinges to form a hinge position 302. The outer ends of the two shaped steel plates 301 swing inward and outward relative to the hinge position 302.

[0063] In construction step 2), the outer ends of the two shaped steel plates 301 are swung outward relative to the hinge position 302 to the limit position until the lower part of the shaped steel plates 301 abuts against the groove side wall 102 of the embedded groove 101 from the inside out, and then multiple inner support bars 303 are arranged in the opening area.

[0064] The water inlet of the water inlet 700 is formed by the hinge 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 700.

[0065] In this embodiment, in construction step 2), after the lower part of the shaped steel plate 301 abuts against the side wall 102 of the embedded groove 101 from the inside out, an outer support strip 304 is arranged at the pouring interval. The two ends of the outer support strip 304 are respectively connected to the adjacent shaped steel plates 301, so that the two adjacent shaped steel plates 301 are spread apart and arranged at a set angle.

[0066] The outer support bar 304 further fixes the two adjacent shaped steel plates 301 by spreading them apart, so as to prevent the spread area of ​​the two shaped steel plates 301 from being squeezed and deformed during the concrete pouring process, which would cause errors in the water inlet 700.

[0067] In construction step 2), the shaped steel plate 301 that abuts against the side wall 200 is the side steel plate 305. The side wall 200 is provided with a stud 306. The side steel plate 305 is provided with a through hole. The stud 306 passes through the through hole and a nut is connected to the stud 306 to fix the side steel plate 305 against the side wall 200. In this way, the end forming arrangement of the water distribution flower wall can be solved, and the end of the water distribution flower wall can be prevented from bursting or leaking concrete during the concrete pouring process.

[0068] In this embodiment, in construction step 4), spacer bars are placed in the pouring interval, and after concrete is poured into the pouring interval, multiple vibrators 800 are inserted into the concrete. The multiple vibrators 800 are arranged in parallel at intervals in the concrete and the multiple vibrators 800 vibrate the concrete.

[0069] During the process of vibrating concrete, the vibrator 800 moves vertically up and down in the concrete at a set frequency, and the upward pulling speed of the vibrator 800 is greater than the downward insertion speed of the vibrator 800.

[0070] The vibrating rod 800 has multiple hinged rods 801 on its outer periphery, and the multiple hinged rods 801 are arranged around the vibrating rod 800 at intervals in the circumferential direction; the vibrating rod 800 is fitted with a horizontally rotating ring 802 on its outer periphery, and the inner end of the hinged rod 801 is hinged to the rotating ring 802 through a hinge shaft 803.

[0071] When the hinge rod 801 swings upward to its limit position, the hinge rod 801 is arranged perpendicular to the vibrating rod 800. When the hinge rod 801 swings downward to its limit position, the hinge rod 801 is attached to the outer periphery of the vibrating rod 800.

[0072] In construction step 4), when the vibrator 800 is inserted into the concrete downwards, due to the resistance of the concrete, multiple hinged rods 801 swing upwards and are arranged horizontally, perpendicular to the vibrator 800; when the vibrator 800 is pulled out of the concrete upwards, due to the resistance of the concrete, multiple hinged rods 801 swing downwards and adhere to the outer periphery of the vibrator 800.

[0073] In construction step 4), when the vibrator 800 is inserted into the concrete and multiple hinged rods 801 are inserted into the concrete, the hinged rods 801 and the vibrator 800 are arranged at an angle and swing up and down repeatedly. The rotating ring 802 rotates around the outer circumference of the vibrator 800 as the vibrator 800 rotates.

[0074] The vibration range of the vibrator 800 is expanded by multiple hinged rods 801. The vibrator 800 uses a rotating ring 802 to improve the vibration mode of the multiple hinged rods 801. When the multiple hinged rods 801 swing up and down, they can rotate and vibrate with the rotation of the rotating ring 802, which improves the vibration effect on the concrete and makes the water distribution flower wall more solid during the forming process.

[0075] In this embodiment, during construction step 4), when pouring concrete into the pouring interval, the hose 900 is used to pour concrete to a set depth into the pouring interval from top to bottom. Then, the hose 900 is pulled out, and the rigid pipe 110 is inserted into the concrete from top to bottom. Concrete is then poured from bottom to top until the pouring interval is filled with concrete.

[0076] The bottom of the hose 900 has multiple branched lower tubes 901, which are arranged around the circumference of the hose 900 at intervals. The upper end of the branched lower tubes 901 is connected to the bottom of the hose 900, and the lower end of the branched lower tubes 901 is arranged downward. A limiting ring 902 is provided between the multiple branched lower tubes 901, which limits the outward expansion of the multiple branched lower tubes 901.

[0077] In construction step 4), the concrete in the hose 900 is poured from top to bottom through multiple branched lower pipes 901 until the concrete in the pouring interval reaches the set depth.

[0078] The bottom of the rigid pipe 110 is provided with a plurality of curved branched upper pipes 111. The plurality of branched upper pipes 111 are arranged around the circumference of the rigid pipe 110 at intervals. The upper end of the branched upper pipe 111 is connected to the bottom of the rigid pipe 110, and the lower end of the branched upper pipe 111 is arranged to bend upward.

[0079] In construction step 4), the bottom of the rigid pipe 110 is inserted into the concrete, and the lower end of the bifurcated upper pipe 111 is submerged in the concrete. The concrete in the rigid pipe 110 is poured from bottom to top through the lower end of the bifurcated upper pipe 111.

[0080] Multiple branched lower pipes 901 are used to increase the pouring range of concrete poured from the hose 900 into the pouring interval, and the limiting ring 902 is used to prevent the multiple branched lower pipes 901 from getting tangled together, thereby affecting the pouring speed.

[0081] By utilizing the raised arrangement of multiple branched upper pipes 111, it is prevented that when the rigid pipe 110 pours concrete into the pouring interval, the concrete will impact the bottom of the pouring interval due to excessive flow velocity, thus reducing the impact of concrete flow on the pouring interval.

[0082] I. Concrete Pouring and Vibration

[0083] The water distribution flower wall is poured in three stages: the base of the water distribution flower wall (100mm), the grid of the water distribution flower wall (500mm), and the top beam of the water distribution flower wall (600mm).

[0084] (1) Key points of construction for the water-retaining flower wall: 100mm base and 600mm top beam.

[0085] Before pouring concrete into the wall, a 5cm thick layer of cement mortar with the same composition as the wall concrete should be poured evenly on the bottom surface. The mortar should be poured into the formwork with a shovel, not poured directly into the formwork with a hopper. The concrete should be poured and vibrated in layers. During pouring, a 900mm flexible hose should be installed and extended into the wall column to ensure that the free fall height of the concrete is less than 2m. The thickness of each layer should be controlled within 50cm. The concrete pouring points should be distributed in a decentralized manner, and the pouring of wall concrete should be carried out continuously.

[0086] (2) Key points for the construction of the 500mm grating of the water distribution flower wall

[0087] Concrete should be poured and vibrated in layers. During pouring, a 900mm flexible hose should be installed and extended 500mm into the grid to ensure that the free fall height of the concrete is less than 2m. The thickness of each layer should be controlled within 50cm. Concrete pouring points should be distributed in a decentralized manner. The pouring of concrete for the wall should be carried out continuously.

[0088] (3) Key points of vibration

[0089] For the concrete pouring of the 500mm grate of the water-retaining flower wall, a low-power vibrator is used. For the concrete pouring of the 100mm base and 600mm top beam of the wall, a ZN-50 planetary high-frequency vibrator (800mm) is used. To prevent the surface concrete from being compacted first and causing segregation between the surface and the underlying concrete, and to prevent the vibrator from merely floating on the concrete surface and touching the reinforcing steel frame, ensuring the concrete is compacted, the vibrator should be inserted quickly and withdrawn slowly, vertically up and down. The insertion points of the vibrator should be evenly spaced, with a spacing not exceeding 500mm. The vibration time must be carefully controlled; over-vibration and under-vibration are both necessary. Generally, the concrete vibration time should be determined when the concrete surface is level, no longer significantly flowing downwards, no longer producing air bubbles, and a layer of mortar appears on the surface. The upper layer of concrete should be poured before the initial setting of the lower layer. When pouring the upper layer, the vibrator should be inserted 50mm into the lower layer of concrete (marked on the vibrator).

[0090] 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 within the protection scope of the present invention.
