Description

Technical Field

[0001] The utility model relates to the technical field of sliding film construction, in particular to a sliding film construction and maintenance device for a silo structure. Background Art

[0002] Slipform construction is a technique used in cast-in-place concrete projects. Compared to conventional construction methods, it boasts faster construction, a higher degree of mechanization, reduced labor and materials required for formwork and scaffolding, and the ability to easily disassemble and flexibly reassemble the formwork, making it reusable. This construction method is frequently used in reinforced concrete chimneys and silo structures, such as cylindrical coal bunkers and granaries.

[0003] During the sliding membrane construction of the silo structure, concrete pouring will begin after the sliding formwork equipment, steel bars and formwork are completed. The initial sliding is to pour the concrete in layers to 1 / 2-2 / 3 of the formwork height. When the strength of the first layer of concrete reaches 0.2-0.4MPa or the concrete penetration resistance reaches 0.30-1.05KN / cm 2 During the initial sliding, the formwork device and the setting state of the concrete are comprehensively checked. After confirming that they are normal, the normal sliding is carried out. During each normal sliding, the formwork is first raised by 5cm, that is, the jack is lifted by 1 to 2 strokes. When the concrete strength reaches 0.2 to 0.4MPa, the sliding can be continued. During the normal sliding stage, the concrete is poured in layers, in circles, and evenly. When pouring the upper layer of concrete, the lower layer of concrete should be in a plastic state. Therefore, the concrete pouring height should not be greater than 0.3m each time, and the interval between each sliding is 1.5 to 2 hours.

[0004] Concrete quality is closely related to its curing process. Meticulous curing of poured concrete is crucial for improving its durability, including strength, impermeability, and crack resistance. After pouring, concrete must be protected from both drying shrinkage due to water loss and thermal contraction caused by premature use and rapid concrete cooling. Therefore, poured concrete must be watered and cured within 8 to 12 hours.

[0005] Traditional silo structure slipform construction typically involves manually pouring concrete using water hoses. However, the slipform platform is limited and located at high altitude. Simultaneous operations such as concrete curing, rebar installation, and concrete pouring present safety risks such as impact, falls, and electric shock, increasing construction risks. Furthermore, manually pouring concrete using water hoses increases construction costs. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] It should be noted that in the description of this utility model, “upper”, “lower”, “top”, “bottom”, orientation or position relationship is based on the attached Figure 1Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0029] In one embodiment, Figure 1 and Figure 2 As shown, the silo structure sliding membrane construction and maintenance device of this embodiment includes a spray assembly and a timed water supply system. The spray assembly is used to spray water onto the silo wall, and the timed water supply system is used to supply water to the spray assembly.

[0030] In this embodiment, the spray assembly includes a first spray pipe 100 and a second spray pipe 200. The first spray pipe 100 and the second spray pipe 200 are both installed at the bottom of the external hanger 400 of the synovial platform.

The first spray pipe 100 is arranged inside the silo structure 300, and the second spray pipe 200 is arranged outside the silo structure 300.

[0031] The timed water supply system includes a booster pump 500, a distribution box 510 for controlling the timing of starting and stopping the booster pump 500, a three-way valve 520, a first solenoid valve rain sensor timer 530, and a second solenoid valve rain sensor timer 540. The booster pump 500 is connected to an external water source or a water tank.

[0032] In this embodiment, the distribution box 510 is electrically connected to the booster pump 500. The water inlet of the three-way valve 520 is connected to the water outlet of the booster pump 500. The two water outlets of the three-way valve 520 are respectively connected to the water inlets of the first solenoid valve rain sensor timer 530 and the second solenoid valve rain sensor timer 540. The water outlet of the first solenoid valve rain sensor timer 530 is connected to the first spray pipe 100, and the water outlet of the second solenoid valve rain sensor timer 540 is connected to the second spray pipe 200. In this embodiment, the booster pump 500 is a 1500W stainless steel multi-stage jet booster pump.

[0033] The silo structure sliding membrane construction and maintenance device of this embodiment can avoid the construction risks brought about by the traditional manual water spraying and maintenance of the silo structure 300, and save construction costs.

[0034] like Figure 3 As shown, in one embodiment, a one-way circuit breaker 511, an AC contactor 512 and a time-space switch 513 connected in sequence are provided inside the distribution box 510; the one-way circuit breaker 511 is connected to an external power supply, and the time-space switch 513 is electrically connected to the booster water pump 500.

[0035] Specifically, the parameter of the single-phase circuit breaker 511 is 20A, the parameter of the AC contactor 512 is 220V, the model is 1210, and the parameter of the time-space switch 513 is 220V / 30A. The single-phase circuit breaker is used for total power control, the AC contactor 512 is used to automatically cut off the current after the water source is cut off to prevent the booster pump 500 from working without water, and the time-space switch 513 is used to provide timed power supply to the booster pump 500.

[0036] In one embodiment, the time-space switch 513 is powered on once every 2 hours, each power-on duration is 20 minutes, and the power-on period is from time T1 to T2; the first solenoid valve rain sensor timer 530 and the second solenoid valve rain sensor timer 540 are both started once every 2 hours, each power-on duration is 10 minutes, and the running period after the first solenoid valve rain sensor timer 530 is started is from time T1 to T3, and the running period after the second solenoid valve rain sensor timer 540 is started is from time T3 to T2, and T3 is the middle time between T1 and T2.

[0037] For example, within 24 hours a day, the time-space switch 513, the first solenoid valve rain sensor timer 530 and the second solenoid valve rain sensor timer 540 are all started and stopped every 2 hours. The time-space switch 513 starts at the top of the hour and lasts for 20 minutes. The first solenoid valve rain sensor timer 530 also starts at the top of the hour and lasts for 10 minutes. The second solenoid valve rain sensor timer 540 starts 10 minutes after the top of the hour and lasts for 10 minutes.

[0038] The water supply is fully controlled by a timer switch, which enables unmanned operation and a high degree of automation.

[0039] It is worth noting that when the silo structure 300 synovial construction and maintenance device is installed and used for the first time, a certain amount of water can be pumped into the first spray pipe 100 and the second spray pipe 200 according to the height of the synovial platform to reduce the delay of the automatic cycle spraying water.

[0040] In one embodiment, the first spray pipe 100 and the second spray pipe 200 are both provided with multiple evenly distributed 360° automatic spray scattering nozzles 600 on the side facing the wall of the silo structure 300; the distance between the 360° automatic spray scattering nozzles 600 and the wall of the silo structure 300 is 0.5m to 0.7m. The distance between any two adjacent 360° automatic spray scattering nozzles 600 is equal, and in this embodiment, the distance between the two nozzles is 3.5m. Then, on the plane where the sliding membrane construction platform is located, there is a 360° automatic spray scattering nozzle 600 every 3.5m on the inner and outer walls of the silo structure 300, spraying water onto the wall.

[0041] In one embodiment, Figure 4As shown, the first spray pipe 100 and the second spray pipe 200 are assembled on the outer hanger 400 of the synovial platform through a plurality of evenly distributed spray pipe connection components; each spray pipe connection component is provided with a sling 700 and a lifting ring, one end of the sling 700 is fixedly connected to the outer hanger 400 of the synovial platform, and the other end of the sling 700 is fixedly connected to the lifting ring, and the lifting ring is sleeved on the first spray pipe 100 or the second spray pipe 200.

[0042] In one specific embodiment, the maintenance effect of the silo structure sliding membrane construction and maintenance device of the present invention is described by taking the sliding formwork project of the raw coal silo wall with a silo height of 45m, a wall thickness of 320mm and a silo diameter of 22m as an example.

[0043] The silo structure sliding membrane construction and maintenance device of the present invention was used to continuously maintain the concrete in the above-mentioned raw coal silo wall sliding membrane project for 7 days, and the rebound strength of ten different areas of the raw coal silo wall was measured. The measurement results are shown in Table 1.

[0044] Table 1 Rebound strength measurement values of different areas of raw coal silo wall

[0045]

[0046] As can be seen from Table 1, by using the curing device of the present invention to cure concrete during the sliding membrane construction process, under the condition of ensuring humidity within 7 days of concrete pouring, the concrete strength value can reach 85.75% of the design value, which can meet the requirements of improving concrete quality.

[0047] Furthermore, if manual curing is used during the sliding membrane construction of the raw coal silo, curing for seven days would involve two people per shift, two shifts per day, and a salary of 300 yuan per person per shift, saving 8,400 yuan in labor costs. Furthermore, the concrete cannot be reused. The curing device of the present invention reduces both investment and labor costs, thus saving construction costs.

[0048] In this embodiment, by adopting a silo structure sliding membrane construction and maintenance device instead of the traditional manual watering maintenance method, the cement is continuously hydrated, the strength is continuously increased, the maintenance meets the specification requirements, and the construction risk and construction cost can be reduced.

[0049] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
