Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology and relates to a concrete paving device for the construction of lining slopes in irrigation canals. Background Technology

[0002] In irrigation systems, canals play a crucial role in water conveyance and distribution. The stability and seepage prevention performance of their slope structures directly affect the canal's flow capacity, engineering safety, and long-term durability. Concrete lining, due to its excellent seepage prevention effect, strong erosion resistance, and long service life, has become the most widely used engineering technique for canal slope reinforcement and protection.

[0003] However, for a long time, the construction of concrete linings in irrigation canals in my country has still largely relied on traditional manual labor. This involves setting up formwork on-site and then manually completing multiple processes such as concrete spreading, vibration, and leveling. This construction method is not only labor-intensive and requires a large workforce, but also has extremely limited efficiency in long-distance projects, making it difficult to meet the stringent requirements of modern irrigation construction in terms of schedule and cost. More importantly, the quality of manual construction is significantly affected by the skill level of the operators. It is difficult to effectively control the density, smoothness, and thickness uniformity of the concrete, making it prone to quality defects such as honeycomb, pitting, and cracks, which seriously affect the overall performance and service life of the lining structure.

[0004] To address the numerous drawbacks of manual construction, mechanized lining technology has been gradually promoted and applied in recent years. Various types of channel lining equipment have emerged on the market, such as slipform lining machines and vibratory beam lining machines, which have improved construction efficiency and concrete forming quality to some extent. However, existing equipment is mostly designed for channel bottom construction or full-section integrated lining designs with specific cross-sections, and performs poorly in handling separate lining of slopes, especially in the "skip-pour" construction process. The skip-pour method, as an advanced construction method for effectively controlling concrete temperature stress and shrinkage cracks, requires intermittent pouring between construction units, with adjacent blocks poured only after the shrinkage of the first block has basically stabilized. This method places higher demands on the mobility, positioning accuracy, and ease of relocation of construction equipment. Existing large and medium-sized lining equipment is typically bulky and complex, making relocation between different sections extremely difficult and unable to adapt to the flexible operating rhythm required for skip-pour construction.

[0005] Furthermore, when performing mechanized lining on channel slopes, a separate track is typically required for the paving equipment. Traditional track systems are cumbersome to install, demanding high foundation flatness, which not only increases preparation time and manpower / material resources but also often results in substandard lining surface flatness due to track installation errors. How to simplify the structure and installation process while ensuring the stability and accuracy of the track system has become a key technical challenge that urgently needs to be addressed to promote the mechanization of slope lining.

[0006] Therefore, there is an urgent need to design a concrete paving device for the skip-layer construction of irrigation canal slope lining to solve the technical problems existing in the current technology. Utility Model Content

[0007] The purpose of this utility model is to at least partially solve some of the technical problems existing in the prior art, and to provide a concrete paving device for the skip-section construction of irrigation canal slope lining. Its structure is reasonable, adapts to the characteristics of skip-section construction of irrigation canal slope lining, and combines the functions of a track and a template. It can achieve rapid positioning and flexible movement. It has important practical significance and engineering value for improving the construction quality of irrigation projects, accelerating the construction progress, and promoting the development of lining construction technology towards lightweight, standardized and efficient directions.

[0008] To solve the above-mentioned technical problems, this utility model provides a concrete paving device for the skip-section construction of lining on the slope of irrigation canals. It includes a pair of track steel templates, a paving assembly, and a traction assembly. The track steel templates separate the area to be constructed from other areas. The paving assembly is perpendicular to the track steel templates and located between the pair. The traction assembly includes a winch motor fixed to the paving assembly, with a steel wire rope connected to the far end of the track steel templates to pull the paving assembly along the length of the track steel templates. The track steel template includes a template body and a template support. The template support is fixed to the side of the template body, and a traction rod is vertically arranged at the end of the template body. The paving assembly includes a paving plate and a baffle. The baffle is vertically fixed to one side of the paving plate, and the winch motor is located on the top surface of the paving plate.

[0009] In some embodiments, the template body is a channel steel, the template support is a steel plate, and the template support is welded to the side of the template body; the dimension of the template support along the length direction of the template body is smaller than the length of the template body.

[0010] In some embodiments, the template supports are a pair, spaced apart on the side of the template body.

[0011] In some embodiments, the traction rod is a steel bar, the end of which is welded to the template body.

[0012] In some embodiments, the paving assembly further includes handrails made of welded steel bars; the handrails are welded to the side of the baffle.

[0013] In some embodiments, the number of winch motors is a pair, which are respectively disposed at both ends of the paving slab.

[0014] In some embodiments, the traction assembly further includes a guide wheel disposed to the side of the winch motor, and the wire rope is connected to the traction rod via a groove in the guide wheel.

[0015] In some embodiments, the length of the paving slab is matched with the spacing between the template bodies, such that the paving slab abuts against the side of the template body.

[0016] In some embodiments, protective members are provided at the ends of the paving slab, which are sleeved on both ends of the paving slab; and the protective members are made of polytetrafluoroethylene.

[0017] In some embodiments, the concrete paving device further includes a support rod connected between the formwork bodies, and a traction rod is provided above the support rod; the traction assembly is equipped with a third winch motor, the wire rope of which is connected to the traction rod on the support rod.

[0018] The beneficial effects of this utility model are: a. It achieves the integration of track and formwork, significantly improving the flexibility and efficiency of skip-formation construction.

[0019] This invention combines the dual functions of a tracked steel formwork and a lateral formwork, eliminating the cumbersome process of separately setting up and leveling dedicated tracks for the paving equipment. The paving assembly moves on a pair of tracked steel formworks via a winch, enabling rapid and precise concrete paving within a single section. After completing one section, the entire device can be quickly disassembled and transferred to the next skip-section section, greatly overcoming the difficulties of traditional large lining equipment in terms of inconvenient relocation and poor adaptability to skip-section methods, effectively shortening the construction cycle.

[0020] b. The simplified and modular structure reduces construction costs and operational difficulties.

[0021] The device mainly consists of a track steel formwork, a paving slab, and a winch. It features a simple structure and low manufacturing and maintenance costs. The track steel formwork forms a stable triangular support structure through formwork supports and traction rods, ensuring rigidity and stability during the paving process. This device requires no complex power or control system, is easy to operate, reduces the technical requirements for operators and the labor intensity of construction, and is particularly suitable for widespread use in small and medium-sized canals or irrigation areas with complex terrain.

[0022] c. It ensured the quality of the lining concrete paving and the accuracy of the cross-sectional dimensions.

[0023] The paving slab length of the paving assembly is precisely matched with the spacing of a pair of track steel formworks, and combined with end guards, ensures that concrete does not leak from both sides during paving, while also creating a smooth lining surface. The track steel formworks, serving as a reliable reference surface, directly control the thickness and alignment of the channel slope lining, effectively avoiding common quality defects such as uneven thickness and poor surface smoothness that are easily caused by manual formwork erection and paving. This ensures the density, smoothness, and overall seepage prevention effect of the lining structure. Attached Figure Description

Detailed Implementation

They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0027] The accompanying drawings in this specification are schematic diagrams used to illustrate the concept of this utility model, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0028] A schematic diagram of a concrete paving device for skip-slab construction of irrigation canal slope lining described in this utility model is shown below. Figure 1 and Figure 2 As shown. The concrete paving device includes a pair of track steel formwork 10, a paving assembly 20, and a traction assembly 30. The track steel formwork 10 consists of a pair, which separates the area to be constructed from other areas. It is laid parallel to the channel slope and separates the area to be constructed from other areas through the side of its formwork body 11, forming the lateral boundary of the pouring space. The paving assembly 20 is perpendicular to the track steel formwork 10 and located between the pair of track steel formwork 10. It can move along the track under the drive of the traction assembly 30 to complete the paving of concrete.

[0029] The traction assembly 30 includes a winch motor 31, such as Figure 5 As shown, it is fixed to the paving assembly 20 by bolts or welding, and the steel wire rope 32 on it is connected to the far end of the track steel template 10 to pull the paving assembly 20 to move along the length of the track steel template 10.

[0030] The rail steel formwork 10 includes a formwork body 11 and a formwork support 12, such as Figure 3 As shown, the template support 12 is fixed to the outer side of the template body 11 (i.e., the side away from the pouring space), and the traction rod 13 is inclinedly connected to the template body 11 and the template support 12, thus forming a stable triangular support structure together with the template body 11 and the template support 12, effectively resisting the lateral pressure during concrete pouring; the paving assembly 20 includes a paving plate 21 and a baffle 22, the baffle 22 is vertically fixed to the side of the paving plate 21 near the top of the channel slope to prevent concrete from overflowing up the slope, and the winch motor 31 is set on the top surface of the paving plate 21.

[0031] Furthermore, the template body 11 is a channel steel with its opening facing the inside of the pouring space. Its channel structure enhances the interlocking with the concrete and improves the quality of the lining edge. The template support 12 is a steel plate and is welded to the side of the template body 11. The dimension of the template support 12 along the length of the template body 11 is smaller than the length of the template body 11, so as to ensure the continuity of the template body when the track is extended.

[0032] The template supports 12 are in pairs, spaced apart on the sides of the template body 11. These pairs of template supports 12 are spaced apart along the length of the template body 11, providing two lower connection points for the traction rod 13.

[0033] The traction rod 13 is a steel bar, with its upper end welded to the web or flange of the template body 11 and its lower end welded to the outer edge of the template support 12, forming multiple inclined tie structures to connect the pairs of track steel templates 10 into a whole, ensuring its stability and constant spacing during construction.

[0034] The paving assembly 20 also includes handrails 23, such as Figure 4 As shown, it is made of steel bars welded together; the handrail 23 is welded to the side of the baffle 22 facing away from the paving plate 21, providing a gripping point for the operator, which facilitates manual intervention during device installation, debugging or emergency.

[0035] The number of winch motors 31 is one pair, which are respectively set at both ends of the paving slab 21. The two winch motors 31 can work synchronously or be controlled independently to achieve smooth straight-line movement of the paving assembly 20 along the track steel template 10 or necessary correction adjustments.

[0036] The traction assembly 30 also includes a guide wheel 33, such as Figure 5 As shown, the guide wheel 33 is mounted on the rope output side of the winch motor 31 via a wheel frame. The wire rope 32 is connected to the traction rod 13 after its direction is changed via the groove of the guide wheel 33. The guide wheel 33 ensures that the output direction of the wire rope 32 is consistent with the extension direction of the track steel template 10, reducing the friction between the wire rope 32 and the track steel template 10 or the ground, thus ensuring the effective transmission of traction force and the service life of the wire rope.

[0037] The length of the paving slab 21 matches the spacing between the template body 11, so that both ends of the paving slab 21 abut against the inner side of the template body 11. This tight fit can effectively scrape off excess concrete and ensure the flatness and preset width of the lining surface.

[0038] The paving slab 21 is equipped with protective components at its ends, which are fitted onto both ends of the paving slab 21; and the protective components are made of polytetrafluoroethylene. As a wear-resistant and friction-reducing component, the protective components reduce the frictional resistance between the ends of the paving slab 21 and the track steel template 10, making the movement smoother, and also avoid direct hard contact between metals, protecting the inner surface of the track steel template 10 from scratches, thereby ensuring the forming quality of the lining edge.

[0039] As a further optimization of this embodiment, the concrete paving device also includes at least one support rod horizontally connected between a pair of template bodies 11, used to further reinforce the overall stability of the track system in front of or behind the paving assembly 20's travel path. A traction rod 13 is provided above the support rod; the traction assembly 30 is equipped with a third winch motor 31, whose wire rope 32 is connected to the traction rod 13 on the support rod. This setup is particularly suitable for ultra-wide channels or working conditions requiring extremely high rigidity of the track system, distributing the force through the central traction point to prevent the track system from deflecting or deforming in the middle during long-distance paving.

[0040] This utility model is not limited to the above-described embodiments. Anyone can derive other products in various forms under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
