Description

Technical Field

[0001] The invention relates to the technical field of slipform concrete construction, and in particular to an assembleable concrete slipform body and a construction method thereof. Background Art

[0002] Concrete face rockfill dam is a type of dam that has been widely used in domestic hydropower stations in recent years. As the main structure for dam anti-seepage, face concrete has an important impact on the comprehensive benefits of concrete face rockfill dam construction. In actual construction, slipform construction is often used.

[0003] Slipform construction is a construction method that uses a hydraulic lifting device to slide the formwork to pour vertical concrete structures. It is to assemble a complete set of hydraulic slipform devices (formwork, enclosure, lifting frame, operating platform, support rod and hydraulic jack, etc.) on the ground (or at a certain elevation) according to the plane shape of the building. The hydraulic jack is used to climb on the support rod, driving the lifting frame, formwork and operating platform to rise together. After each layer of concrete is poured, the formwork is slid until the structure is poured.

[0045] See also Figure 1 As shown in the figure, an assembled concrete slipform body includes a side form 1, a slipform 2, a traction device 3, a pouring device 4 and a monitoring device 5.

[0046] See also Figure 2 As shown in the figure, the side formwork 1 includes a plurality of shaping plates 11, a reinforcement frame 12 and a track 13 arranged on both sides to limit the lateral flow of concrete. The reinforcement frames 12 are respectively connected to the adjacent shaping plates 11 and support the track 13. The track 13 is arranged above the reinforcement frame 12. The reinforcement frame 12 can not only reinforce the shaping plates 11, but also provide installation support for the track 13. The shaping plates 11, the reinforcement frames 12 and the track 13 are all prefabricated, which are made in advance according to the size and assembled on site.

[0047] Specifically, the shaping plates 11 are preset on both sides according to the slope design, and the two adjacent shaping plates 11 are fixed by a fixing frame 12. The adjacent fixing frames 12 are fixed to each other by bolts, etc., and are fixed to the ground by bolts, etc. After the fixing frames 12 are fixed, the rails 13 are installed above the fixing frames 12. The rails 13 can also be fixed above the fixing frames 12 by screws or welding.

[0048] The track 13 is provided with jacks 131 at equal intervals, and the jacks 131 are equipped with matching stoppers 132. When the slide is raised, the stoppers 132 are inserted into the jacks 131 of the track 13 at the rear end, which provides better safety. In an emergency such as when the traction wire rope 32 breaks, the stoppers inserted into the jacks will resist the slide from behind to prevent it from falling, thus ensuring its safety.

[0049] See also Figure 2 and Figure 3 The slipform 2 is set on the track 13. The slipform 2 includes a bottom steel panel, a steel truss, a working platform and rollers 21. The bottom steel panel and the steel truss are set horizontally with the slope. The working platform includes a front trimming platform 22 and a rear operating platform 23. The operating platform 23 and the trimming platform 22 are set horizontally, and guardrails 24 are provided on both sides. The rollers 21 roll in the track 13. The slipform 2 has a stable structure and moves on the track 13 through the traction device 3. The trimming platform 22 is a double-layer design. The lower layer is close to the poured concrete, which is convenient for the staff to handle the concrete. The higher layer has a better field of view and a higher height, which is convenient for timely discovery of problems on the construction site and for command and issuance of orders.

[0050] The angles of the operating platform 23 and the trimming platform 22 are adjustable. The sliding form 2 is provided with fixed slots of various levels. The operating platform 23 and the trimming platform 22 are both provided with support frames, which are clamped in different fixed slots to support the operating platform 23 and the trimming platform 22. For different slope angles, the operating platform 23 and the trimming platform 22 with adjustable angles can be adjusted to achieve the horizontal setting of the operating platform 23 and the trimming platform 22, which has a wider scope of application and is convenient for large-scale promotion and use. The way of adjusting the angles of the operating platform 23 and the trimming platform 22 is reflected in the existing technology, so no detailed description is made.

[0051] Infrared emitters 51 are arranged on both sides of the sliding mold 2 and are arranged toward the track 13 .

[0052] Infrared receivers 52 are arranged at equal distances on the tracks 13 on both sides, and the infrared receivers 52 match the infrared transmitters 51. During the movement, the infrared transmitters 51 match different infrared receivers 52. In this embodiment, the spacing between the infrared receivers 52 is 15 cm.

[0053] See also Figure 3 and Figure 4 The monitoring device 5 includes an infrared transmitter 51, a plurality of infrared receivers 52 and a display panel 53. The infrared receivers 52 are numbered from bottom to top, and the display panel 53 displays the numbers of the infrared receivers 52 on both sides that receive the infrared signals. The tilt conditions on both sides are displayed according to the numbers, which is more intuitive. Through the monitoring device 5, the infrared receiver 52 receives the signal of the infrared transmitter 51, and the display panel 53 displays the numbers of the infrared receivers 52 on both sides. The staff can observe the tilt condition of the sliding form in time, and can make adjustments in time according to the tilt condition, so that the sliding form operation is safer.

[0054] Specifically, the infrared receivers 52 arranged in the tracks 13 on the left and right sides are numbered 1, 2, 3, etc. from bottom to top. The infrared receivers 52 at the same height have the same number. The display panel 53 displays the numbers of the infrared receivers 52 on both sides that receive the infrared signal. When the infrared transmitter 51 is located between the two infrared receivers 52, the display panel 53 displays the number of the infrared receiver 52 that received the signal last. According to the numbers of the infrared receivers 52 displayed on both sides, the staff can intuitively judge the tilt state of the sliding form 2. The display panel 53 is provided with a prompt light. When the difference between the two displayed numbers is less than 2, it is displayed as a green light; when the difference between the two displayed numbers is greater than or equal to 2, it is displayed as a red light. For example, when the numbers displayed on the display panel 53 are: 10 and 11, the prompt light is displayed as a green light. When the displayed numbers are 15 and 17, the prompt light is displayed as a red light, and an alarm prompt is issued to remind the staff to pay attention.

[0055] See also Figure 5The traction device 3 is connected to both sides of the sliding form 2 to drive the movement of the sliding form 3. The traction device 3 includes two winches 31, a traction wire rope 32, a mounting seat 33, and a control device. Two lifting rings are provided on both sides of the sliding form 2, and the traction wire rope 32 is connected to the two lifting rings on the same side. The sliding form 2 is pulled by the double lifting rings on both sides connected by the winch 31. The structure is stable and safe. The simultaneous operation and separate operation of the winches on both sides can be controlled by the control device 34. The control device 34 is provided with a main switch including the simultaneous operation of the winches 31 on both sides, a left switch for the operation of the left winch 31 alone, and a right switch for the operation of the right winch alone. The main switch is set separately, and the left switch and the right switch are covered by a safety shell to prevent accidental touch. When the prompt light is green, the safety shell covers it. When the prompt light is red, the safety shell can be automatically popped open, which is convenient for the staff to use for adjustment.

[0056] The winch 31 is arranged on the sliding formwork, the mounting seat 33 is fixed on the top of the slope, and a pulley is provided. The traction wire rope 32 extends from the winch 31, passes through the pulley on the mounting seat 33, and is connected to the lifting rings on both sides of the sliding formwork 2. When the sliding formwork 2 itself needs counterweight, the winch 31 is arranged on the sliding formwork to play a partial counterweight effect, and the connection between the control device and the winch 31 is also simpler and more convenient.

[0057] The mounting seat 33 comprises a bottom beam 331, a main support 332, a front diagonal support 333, and a rear diagonal support 334. A pulley 335 is provided on the main support 332. The fixing stability of the mounting seat is stronger.

[0058] The pouring equipment 4 performs pouring work. The pouring equipment 4 includes a concrete tank truck 41 arranged on the top of the slope and a chute connected to the concrete tank truck 41. The chute is a negative pressure chute 42. The tail end of the negative pressure chute 42 is an open chute 43. The concrete pouring is more dispersed, which is convenient for the concrete pouring work.

[0059] A rain shelter 25 is provided above the slipform 2, and a water spray pipe 26 is provided on the operating platform 23. The rain shelter can shelter workers from rain on rainy days, which is convenient for construction on rainy days and more humane. The water spray pipe facilitates the subsequent maintenance of the poured concrete in a timely manner, without the need to arrange personnel separately for maintenance work. At the same time, compared with watering the site from both sides, the operating platform 23 can be operated more conveniently and the watering is more uniform.

[0060] Anti-skid safety protection devices are provided on both sides of the slip form 2, and the anti-skid safety protection devices are hand chain hoists. They are initially fixed during the slip form installation process and removed after trial sliding, which is safer.

[0061] See also Figure 6 , a construction method of an assembled concrete slipform body, comprising the following steps:

[0062] S1. Slope design and pre-construction preparation: Design the dimensions according to the construction requirements, make the side form 1 and the sliding form 2 according to the dimensions, and perform preliminary treatment on the cushion layer;

[0063] S2. Installation of the side form 1: install the shaping plates 11 in order from top to bottom at the designated position for preliminary fixation, install the fixing frame 12 between two adjacent shaping plates 11, and after the shaping plates 11 and the fixing frame 12 are all installed, install the track 13 on the fixing frame.

[0064] The side formwork 1 is installed after the bottom water stop is installed. Before installation, the surface of the shaping plate 11 is coated with a mold release agent. When installing the side formwork, ensure that the water stop is installed firmly and stably, and pay attention to protecting the buried water stop. A slope trolley (a steel bar trolley can be used) is arranged on both sides of the warehouse surface, and a 3T winch is used to pull and transport materials. The joints between the shaping plates 11 must be flat, tight and without misalignment. The reinforcement support of the shaping plate 11, that is, the fixed frame 12, must be inspected and maintained to prevent the shaping plate 11 from deformation or displacement. During the concrete pouring process, a special person is assigned to regularly inspect and adjust the shape and position of the shaping plate 11.

[0065] S3, installation of the slipform 2: After the surface reinforcement is erected, the mounting seat 33 is fixed on the top of the slope. During the fixing process, the corresponding position of the lifting ring of the slipform 2 needs to be determined first, and the position of the pulley 335 is determined according to the lifting ring. After the mounting seat 33 is installed, the slipform 2 is transported to the top of the slope in sections for assembly. The slipform 2 is hoisted onto the track 13 of the side form 1, and the winch 31 is installed on the slipform 2, and the counterweight is added in time. The slipform 2 is first fixed with a hand winch safety rope, and then the traction wire rope 32 of the winch 31 is passed around the pulley 335 on the mounting seat 33 and fixed with the lifting ring on the slipform 2. The support frame of the operating platform 23 and the trimming platform 22 is clamped in the corresponding fixed card slot, and the operating platform 23 and the trimming platform 22 are adjusted so that the two platforms are in a horizontal state. Then a trial slide is carried out, and the hand winch is removed after two to three trial slides. The hand winch first fixes the slipform to facilitate the trial slide, which ensures the safety of the slipform 2 just set on the track 13.

[0066] At the same time, during the installation of the track 13 , an infrared receiver 52 is arranged on the side of the track 13 , and an infrared transmitter 51 is also arranged on the side of the sliding form 2 .

[0067] S4, the slide form 2 slides down to the bottom of the slope: the chute is placed on the working platform of the slide form 2. During the sliding of the slide form 2, the chute is installed synchronously, avoiding the trouble of workers needing to install the chute in separate steps. The chute is a negative pressure chute 42, and the tail end of the negative pressure chute 42 is an open chute 43.

[0068] S5, concrete pouring and slipform 2 rising: concrete is poured through pouring equipment 4. After each layer of concrete is poured (the height of one layer of concrete is 25-30 cm), the slipform 2 is lifted once (the rising amplitude is controlled at about 30 cm). The sliding speed of the slipform is adapted to the pouring strength and demoulding time. The average sliding speed is controlled at 1.0-2.0 m / h. The specific sliding speed is determined by on-site tests on the construction site. The sliding interval time does not exceed 30 minutes, and the maximum sliding speed does not exceed 2 m / h. If the slipform is lifted too fast, the demoulding concrete may flow. If it is too slow, the concrete surface may crack. The slipform should rise steadily and evenly. The staff trims the poured concrete on the trimming platform 22, performs subsequent treatment on the trimmed concrete on the operating platform 23, and inserts a limit block in the socket of the rear track. Subsequent treatment includes water treatment, which includes laying straw bags and using a sprinkler pipe for watering. The staff carried out maintenance work in a timely manner to ensure the quality of concrete pouring.

[0069] The control device 34 of the traction device 3 and the display panel 53 of the monitoring device 5 are arranged on the sliding form 2. The staff on the dressing platform 22 of the sliding form 2 controls the simultaneous operation or the separate operation of the hoists 31 on both sides according to the numbers of the infrared receivers 52 displayed on the display panel 53. The staff can control the operation of the hoists according to the numbers of the infrared receivers 52 on both sides displayed to ensure the safety of the sliding form operation.

[0070] Specifically, the process of the staff making adjustments according to the detection device 5 is as follows: when the display panel shows that the numbers on both sides are less than 2, the staff can directly press the main switch, and the winches 31 on both sides will run at the same time, driving the sliding form 2 to rise. When the display panel shows that the numbers on both sides are greater than 2, it is necessary to adjust and then turn on the main switch to rise. For example, when the number 10 is displayed on the left and the number 12 is displayed on the right, the right side of the sliding form is high and the left side is low, and the inclination is large. The staff can press the left switch alone, and the winch 31 on the left will run first. After reducing the inclination of the sliding form 2, continue to press the main switch, and the sliding form 2 will rise as a whole and continue to work normally.

[0071] It should be noted that although the above embodiments have been described in this article, the scope of patent protection of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures, equivalent processes or equivalent functional transformations made using the contents of the present specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the patent of the present invention.
