Description

Technical Field

[0001] The present invention relates to the technical field of ditch construction, and particularly relates to a ditch stretching device and a stretching method thereof. Background Art

[0002] Ditches are usually used in urban drainage or agricultural irrigation. In order to achieve good drainage effect, low permeability, convenient construction and low cost, concrete is usually used to lay the dug ditches to form concrete ditches. In the traditional construction method, a number of templates need to be fixed before laying the concrete, then pouring is carried out, and then the templates of the completed section of the ditch are removed and shifted for fixing. It can be seen that the traditional construction method is complex, and the structure has joints. The turnover times of template installation are many, the labor cost is high, and manual installation of templates, manual pouring and vibrating of concrete, vibrating and form removal and reinstallation of templates are required for multiple processes of construction. Not only is it difficult to ensure the construction quality of the concrete, but when the formwork is removed after the concrete dries, it is easy to have an uneven surface due to adhesion, affecting the integrity. In order to overcome the defect of uneven surface, an interface agent needs to be brushed on the concrete surface. After some formworks bulge during use, additional processes such as chiseling and grinding are required, and the concrete will be damaged, thus shortening the service life of the ditch. Summary of the Invention

[0003] In view of this, the present invention provides a ditch stretching device and a stretching method thereof to solve the above technical problems.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A ditch stretching device includes a track fixedly connected to the ditch bottom plate and a stretching mechanism main body moving along the track. The stretching mechanism main body includes at least one set of stretching walking mechanisms moving along the track and two mutually parallel template systems. The stretching walking mechanism is located between the two template systems. The template system includes two mutually parallel templates, and a cement pouring cavity is formed between the two templates. At least one leveling mechanism is provided above the cement pouring cavity.

[0006] Further, a number of vibrators are provided on the outer side surface of the template system.

[0007] Further, the stretching walking mechanism includes an equipment system, a horizontal linear driving mechanism provided on the equipment system, a plurality of walking wheels and a self-suction module provided at the bottom of the equipment system. A push-pull head connected to the movable end of the horizontal linear driving mechanism is integrally connected to the two template systems.

[0008] Further, the push-pull head includes a cross beam frame extending in the width direction and connected to the horizontal linear drive mechanism, and connecting side frames are connected to both ends of the cross beam frame and are connected to the corresponding formwork system.

[0009] Further, the horizontal linear drive mechanism is a hydraulic jack.

[0010] Further, the rail is an I-beam, and all the traveling wheels on both sides of the equipment system are distributed vertically to form a traveling channel, and the corresponding upper flange of the rail is located in the corresponding traveling channel.

[0011] Further, the height of the formwork is increased by 100 mm on the basis of the height of the ditch wall.

[0012] Further, the main body of the stretching mechanism further includes two rows of F-shaped side frames arranged back to back. Two of the F-shaped side frames in the same row are fixedly connected into one body through a formwork support frame. The inner sides of all the F-shaped side frames in the same column are connected to the outer sides of the corresponding formwork system through a plurality of channel steels to form one body, and the inner side of the formwork system is connected to the corresponding formwork support frame through a corresponding vertical frame.

[0013] The present application also discloses another technical solution:

[0014] For the ditch stretching method of the ditch stretching device as described above, the working steps are as follows:

[0015] S01: Pour ditch concrete on the prepared foundation according to the design elevation, and carry out plastering and troweling to form a ditch bottom slab;

[0016] S02: Set a center line on the ditch bottom slab, add stake marks at a certain density on the center line and on both sides of the center line, and install the rail along the center line;

[0017] S03: Install the main body of the stretching mechanism on the rail;

[0018] S04: Use the concrete conveying main pipe and the conveying branch pipe to simultaneously convey concrete into the cement pouring cavities of the formwork systems on both sides;

[0019] S05: At the initial pouring, the main body of the stretching mechanism remains stationary. When the induction system of the main body of the stretching mechanism senses that the height and length of the cement in the cement pouring cavity reach the set values, the control system of the main body of the stretching mechanism controls the vibrator and the stretching traveling mechanism to work, and uses the leveling mechanism to level and smooth according to the ditch wall elevation, so as to complete the seamless pouring of the ditch wall at one time.

[0020] Further, the induction system is attached to the formwork system.

Detailed Description of the Specific Embodiment

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0030] Refer to Figures 1 to 4 For further illustration of the present application, as Figure 1 and Figure 2A ditch stretching device shown in the figure includes a track 3 fixedly connected to the bottom plate 1 of the ditch and a stretching mechanism main body moving along the track 3. The stretching mechanism main body includes at least one group of stretching walking mechanisms 7 moving along the track 3 and two mutually parallel template systems 8. The stretching walking mechanism 7 is located between the two template systems 8. The template system 8 includes two mutually parallel templates, and a cement pouring cavity is formed between the two templates. At least one leveling mechanism 6 is provided above the cement pouring cavity. The leveling mechanism 6 automatically controls the leveling of the fixed elevation limit of the ditch wall 2 through elevation setting. Among them, the template can be formed by splicing multiple sub-templates, enabling the template to be made into any required size and meeting different requirements.

[0031] Preferably in this application, the stretching mechanism main body includes two groups of the stretching walking mechanisms 7. The two groups of the stretching walking mechanisms 7 are respectively close to the head end and the tail end of the template system 8, making the power large and the overall stability of the ditch stretching device good during operation.

[0032] Preferably in this application, the template is made of 8mm steel plate and after being polished, it has the effect of self-cleaning and not sticking to cement, enabling the template to be quickly separated from the ditch wall 2, making the wall surface of the ditch wall 2 smooth and flat, and not requiring re-plastering of the wall surface of the ditch wall 2, saving processes.

[0033] Preferably in this application, the leveling mechanism 6 is a liftable flat plate or a liftable electric leveling device. The electric leveling device includes an electric turntable, but is not limited to the above two structures.

[0034] A number of vibrators 4 are attached to the outer side surface of the template system 8. When the vibrators 4 work, they vibrate the template together, causing the water vapor inside the concrete to rise due to vibration and achieving vibration compaction, enabling the concrete to be compacted and the ditch wall 2 to be tightly compacted.

[0035] As Figure 2 and Figure 3 shown, the stretching walking mechanism 7 includes an equipment system 71, a horizontal linear driving mechanism arranged on the equipment system 71, a plurality of walking wheels 76 and a self-suction module 77 both arranged at the bottom of the equipment system 71. A push-pull head connected to the movable end of the horizontal linear driving mechanism is integrally connected to the two template systems 8. Among them, the walking wheels 76 move along the track 3, and the self-suction module 77 adsorbs to the track 3 to keep the equipment system 71 in a stationary state.

[0036] The working principle of the stretching walking mechanism 7 is as follows: The self-suction module 77 adsorbs to the track 3 to keep the equipment system 71 in a stationary state. The horizontal linear drive mechanism drives the push-pull head to slide along the channel between the two formwork systems 8 and move closer to the equipment system 71. When the push-pull head moves, it drives the overall skeleton system with the two formwork systems 8 to move. After the push-pull head moves a certain distance, the self-suction module 77 releases the track 3. Due to the friction between the formwork system 8 and the ditch wall 2, when the horizontal linear drive mechanism operates, it will drive the equipment system 71 to move forward, and the overall skeleton system remains stationary, completing one crawl. Repeating the above actions can achieve continuous crawling. During the continuous crawling of the formwork system 8, concrete pouring is carried out, enabling the ditch wall 2 to be poured in one go without joints, with a short construction period, no need for manual operation, and simple installation.

[0037] Specifically in this application, the push-pull head includes a crossbeam frame 73 extending in the width direction and connected to the horizontal linear drive mechanism. Both ends of the crossbeam frame 73 are connected with connection side frames 74 connected to the corresponding formwork system 8. The crossbeam frame 73 is made of a square tube with dimensions of 200mm * 200mm * 5mm. The connection side frame 74 includes multiple connecting tubes, and the connecting tubes are made of square tubes with dimensions of 100mm * 200mm * 5mm. Moreover, the connecting tubes are connected to the crossbeam frame 73 and the corresponding formwork system 8 through multiple connecting bolts 75. Among them, a connecting plate is connected to the end of the crossbeam frame 73.

[0038] Preferably in this application, the horizontal linear drive mechanism is a cylinder or an oil cylinder or an electric push rod or a linear motor or other linear modules.

[0039] Specifically in this application, the horizontal linear drive mechanism is a hydraulic jack 72.

[0040] As Figure 4 shown, the track 3 is an I-beam. All the walking wheels 76 on both sides of the equipment system 71 are distributed vertically to form a walking channel. The corresponding upper wing plate of the track 3 is located in the corresponding walking channel, which can limit the position of the formwork system 8 and prevent the formwork from vibrating and floating or sinking during the pouring process.

[0041] The height of the formwork is increased by 100mm based on the height of the ditch wall 2 to prevent excess concrete from overflowing during the leveling process and affecting the processing quality of the ditch.

[0042] The main body of the stretching mechanism further includes two rows of F-shaped side frames 10 arranged back to back. Two of the F-shaped side frames 10 in the same row are fixedly connected into one body through a formwork support frame 5. The inner sides of all the F-shaped side frames 10 in the same column are connected to the outer sides of the corresponding formwork system 8 through a plurality of mutually parallel and horizontally extending channel steels 9 to form an integral body. The inner side of the formwork system 8 is connected to the corresponding formwork support frame 5 through a corresponding vertical frame. With the above structure, the formwork system 8 is fixed while there is no occlusion between the two formworks, making the integral property of the gutter wall 2 better. With the above structure, a strong overall skeleton system can be formed, and the overall stability is good during the climbing and stretching of this application. An intelligent control module is provided on the overall skeleton system, and the intelligent control module controls whether the stretching walking mechanism 7 and the vibrator 4 work according to the received control information.

[0043] Another technical solution is also disclosed in this application:

[0044] For the gutter stretching method of the gutter stretching device as described above, the working steps are as follows:

[0045] S01: Pour gutter concrete on the prepared foundation according to the design elevation, and carry out leveling and troweling to form the gutter bottom slab 1. Among them, before the foundation treatment, it is necessary to first remove surface vegetation, sundries, accumulated water, silt and topsoil, treat the pond, and then carefully compact and treat the base to meet the specifications and design requirements;

[0046] S02: Set the center line on the gutter bottom slab 1, add marking stakes at a certain density on the center line and on both sides of the center line, and install the track 3 along the center line. Among them, the track 3 is fixedly connected to the gutter bottom slab 1 by expansion bolts;

[0047] S03: Use a crane to position the main body of the stretching mechanism and install the main body of the stretching mechanism on the track 3, and carry out debugging;

[0048] S04: Use the main concrete conveying pipe and the conveying branch pipe to simultaneously convey the ecological concrete into the cement pouring cavities of the formwork systems 8 on both sides to realize the simultaneous pouring of the gutter walls 2 on both sides;

[0049] S05: At the initial pouring, the main body of the stretching mechanism remains stationary. When the induction system of the main body of the stretching mechanism senses that the height and length of the cement in the cement pouring cavity reach the set values, the control system of the main body of the stretching mechanism controls the vibrator 4 and the stretching walking mechanism 7 to work, and uses the leveling mechanism 6 to level and trowel according to the elevation of the gutter wall 2 to complete the seamless pouring of the gutter wall 2 at one time.

[0050] S06: Curing. The curing steps are as follows: 1. After the pouring is completed, check the compactness. If it is qualified, curing can be carried out, and an impermeable film is used for moisture conservation curing; 2. The curing period shall not be less than 7 days, and traffic shall be closed during the curing period.

[0051] Preferably in this application, during the initial pouring, when the induction system of the main body of the stretching mechanism senses that the length in the cement pouring cavity reaches 1 meter, the control system controls the vibration motor 4 to start according to the feedback signal received from the induction system. After vibrating for a set time, then the vibration motor 4 and the stretching walking mechanism 7 work simultaneously, continuously pouring and vibrating the concrete until the pouring is completed, forming a concrete water channel without joints at one time.

[0052] The induction system is attached to the formwork system 8, and the control system is arranged on the overall framework system, and induction is generated by the stress generated by the accumulation of concrete in the formwork system 8.

[0053] During actual use, the induction system can be a pressure sensor, which can trigger the pressure sensor to obtain an induction signal when the formwork system 8 accumulates concrete and causes slight deformation at the corresponding position of the formwork; the induction system can also be a length sensor.

[0054] Ecological concrete uses oyster shell ash as a cementing material to replace cement. The concrete admixture uses broken bricks and broken concrete blocks of construction waste to extract better coarse aggregates and coal cinders through equipment crushing, and then combines and proportions them to produce the best concrete, which meets the current national requirements of promoting green environmental protection, carbon peak, and intelligent construction. Moreover, using oyster shell ash as a cementing material to replace cement has high flexural strength and good flexibility, extends the service life of the water channel, and can prevent the water channel from causing damage to people during earthquakes.

[0055] Using this application for water channel stretching, several processes such as formwork installation, concrete pouring, and plastering are combined into one process. It is fast, has no construction joints, does not require manual operation, saves labor and material costs, reduces the cost, is easy to install, has no technical content, has a short construction period, ensures product quality, is convenient for transportation, has no intersection with other processes, is energy-saving, environmental protection, noise reduction, protects the environment, and the concrete surface is smooth and has high strength without the need for a plastering process during on-site construction.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
