Description

Technical Field

[0001] This invention relates to the field of ditch construction technology, specifically to a rapid construction structure and method for a water-permeable and material-saving ditch. Background Technology

[0002] Ditches are important infrastructure in water conservancy projects, farmland irrigation, and municipal drainage. Traditional ditch construction often uses formwork erection and cast-in-place concrete technology, or precast component assembly technology. Among these, the formwork erection and cast-in-place technology has problems such as complicated construction steps, large consumption of formwork materials, long construction period, high labor costs, and structural damage caused by formwork removal. Although the precast component assembly technology shortens the construction period, the precast components are heavy, requiring large hoisting equipment, and are difficult to adapt to irregularly shaped ditches. At the same time, quality problems such as leakage and cracking are prone to occur at the joints of components.

[0003] Furthermore, traditional ditch construction often prioritizes structural strength while neglecting material conservation and ecological considerations. It consumes large amounts of cement grout, leading to resource waste, and the riverbanks are mostly rigid structures, lacking space for planting greenery and resulting in poor ecological benefits. Therefore, developing a material-saving, efficient, adaptable, and ecologically sound ditch construction device and method has become an urgent technical problem to be solved in the field of water conservancy construction.

[0004] Chinese Patent 2025104618393 discloses a combined structure of prefabricated ditch and retaining wall and its construction method. The structure includes a ditch and a retaining wall. The ditch is constructed by interlocking a base plate and wall panels using zigzag grooves and tenons. The outer surface is layered with hydraulic fabric and a hydraulic membrane to enhance impermeability. The retaining wall uses right-angled triangular supports and hollow reinforced concrete panels, fixed with pins and connected to the ditch via cables inside conduits, improving anti-overturning and anti-sliding stability. The construction method includes steps such as prefabrication of components, layered laying of impermeable materials, modular assembly, and backfilling with greenery. This patent relates to prefabrication but not to water seepage and material conservation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a rapid construction structure and method for drainage ditches that is both water-permeable and material-saving, solving the problems of high material consumption, long construction periods, poor adaptability, and insufficient ecological benefits in traditional ditch construction. This structure acts as a template, allowing cement grout to be injected for rapid construction. Its principle is similar to injecting grout into a cavity, where the grout quickly solidifies and forms the ditch structure through water permeation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rapid construction structure for a water-permeable and material-saving ditch includes: The main body includes a fabric layer and a cavity structure formed by support. The fabric layer includes a thickened canvas surface layer and a thickened canvas bottom layer. The thickened canvas surface layer and the thickened canvas bottom layer are connected by several rubber support columns to form a cavity structure that can be filled with cement slurry. The cavity structure is a honeycomb-shaped material-saving structure. Grouting assembly: At least one grouting hole is provided on the left and right sides of the main body, and a threaded grouting nozzle is provided at the grouting hole, and the threaded grouting nozzle is provided with a grouting hole cover; Fixing components: Several fixing holes are provided on the left and right edges of the main body. Anchoring expansion bolts are adapted to pass through the fixing holes. The anchoring expansion bolts include an expansion bolt sleeve and a bolt structure.

[0007] Furthermore, the cavity structure of the honeycomb-shaped material-saving structure has a hexagonal array at the bottom, which reduces the amount of cement slurry filling. The size of each cavity is adapted to the specifications of the ditch, and the whole device is spliced ​​together according to the actual length of the ditch.

[0008] Furthermore, both the thickened canvas surface material and the thickened canvas bottom material are made of wear-resistant and tensile-resistant thickened canvas material, which is resistant to acids and alkalis and water immersion, and is suitable for long-term use in ditches; the thickened canvas material has water-permeable properties, which accelerates the solidification of cement slurry.

[0009] Furthermore, the rubber support column is made of elastic rubber, which adapts to the shape changes of the ditch and groove, and can support the cavity structure to maintain structural stability.

[0010] Furthermore, the expansion bolt sleeve and the bolt have corresponding barb structures.

[0011] The above-mentioned construction method for a rapid construction structure of a water-permeable and material-saving ditch includes the following steps: S1, Trench finishing

[0012] Excavate the trench, clear debris from the excavation area, and repair the bottom and sides of the trench to ensure that the surface of the trench is flat and the slope meets the design requirements. S2, Installation

[0013] Unfold the main body of the structure and lay it flat in the prepared ditch, so that the thickened canvas bottom layer of the main body is in contact with the bottom of the ditch, with the thickened canvas top layer facing up. Adjust the position of the device to fit the contour of the ditch. S3, Slurry Injection

[0014] Cement grout is injected into the cavity structure of the main body through the grouting hole and the threaded grouting nozzle. During the injection process, the fit of the device is observed in real time to ensure that the grout fills the cavity evenly. S4. Surface leveling

[0015] After the cement grout is injected, cover the grouting hole with a cap, and manually level the surface of the device to ensure that the device fits tightly with the trench and the surface is flat and smooth. S5, Device Fixing

[0016] Anchor bolts are installed at the fixing holes on both sides of the ditch to fix the main body to the original geological structure of the embankment and prevent the device from shifting or sliding. S6. Backfilling and Greening

[0017] Backfill the embankment around the anchor expansion bolts with soil and compact the backfill soil using light equipment. S7, Maintenance Acceptance

[0018] The main body filled with cement grout is naturally cured. After the cement grout has completely solidified, the strength, flatness and fixing effect of the ditch structure are checked. Once the inspection is passed, the ditch construction is completed.

[0019] Furthermore, in step S3, the cement slurry is a quick-setting cement slurry. By utilizing the water-permeable properties of the thickened canvas fabric, the slurry setting cycle is shortened. The amount of grout injected is determined according to the volume of the cavity structure and the design strength of the ditch, which reduces the amount of slurry used by 30%-50% compared to the traditional pouring process.

[0020] Furthermore, in step S5, the anchoring expansion bolts are evenly distributed along the length of the ditch, with a spacing of 50-100cm. The anchoring depth of the expansion bolts is not less than 2 / 3 of the thickness of the backfill soil on the embankment, ensuring that the fixed bearing capacity of the device meets the design requirements.

[0021] Furthermore, in step S6, green vegetation is planted on the surface of the backfill soil to achieve ecological restoration.

[0022] The beneficial effects of this invention are: 1. Material saving and consumption reduction: The honeycomb cavity structure reduces the amount of cement slurry by 30%-50% compared to the traditional planar structure, thus reducing material costs; the thickened canvas fabric has strong water permeability, which accelerates the solidification of the slurry, shortens the curing cycle, and further saves construction time.

[0023] 2. High efficiency and convenience: The device has a flexible fabric structure, which eliminates the need for templates and large hoisting. The laying and leveling can be completed manually, simplifying the construction steps and shortening the construction cycle by more than 60% compared with traditional processes.

[0024] 3. High adaptability: Flexible fabric can fit into ditches and grooves of different shapes and slopes, solving the problem that prefabricated components are difficult to adapt to irregular ditches, and has a wide range of applications.

[0025] 4. Safe and reliable: The device is lightweight, reducing the safety risks of hoisting operations; the anchoring expansion bolts are firmly fixed, and the backfill soil is compacted to ensure the stability of the ditch structure; the fabric is water-resistant and acid and alkali-resistant, suitable for the long-term use environment of the ditch.

[0026] 5. Eco-friendly: Green plants can be planted after the embankment is backfilled to restore the ecological function of the embankment, taking into account both water conservancy function and ecological restoration, which is in line with the concept of green construction.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1: Referring to Figures 1-6, a rapid construction structure for a water-permeable and material-saving ditch includes a main fabric layer, a grouting assembly, a fixing assembly, and a material-saving structure. The main fabric layer consists of a thickened canvas surface layer 11 and a thickened canvas bottom layer 12, both made of 5mm thick, wear-resistant, thickened canvas that is resistant to water immersion and has a tensile strength ≥1500N, allowing it to adapt to the ditch's water environment for extended periods. The two layers are connected by several rubber support columns 16, each a 10cm high, elastic rubber column with a diameter of 8cm, evenly distributed to form a honeycomb-like cavity structure 13. The inner diameter of each cavity is 20cm, and the array of cavities is adapted to the specifications of conventional farmland irrigation ditches. Grouting assembly: Four grouting holes 15, each 5cm in diameter, are evenly opened on the thickened canvas surface layer 11. Each grouting hole 15 is welded with a threaded grouting nozzle 17 and a matching grouting hole cap 18. The cap is threadedly connected to the grouting nozzle, providing good sealing performance and preventing grout leakage. Fixing components: Several fixing holes 14 are opened along the length of the device edge, with a hole diameter of 3cm and a spacing of 80cm; anchoring expansion bolts 2 are inserted into the fixing holes 14, the expansion bolt sleeve 21 of the anchoring expansion bolt 2 is 30cm long, and the bolt structure 22 is made of stainless steel, which is corrosion resistant and has strong tensile strength.

[0030] Example 2: The construction method for a rapid construction structure of a water-permeable and material-saving ditch, as described in Example 1, was applied to the construction of irrigation ditches in a certain area. The ditch specifications are: bottom width 2m, mouth width 3m, depth 1.5m, and the ditch has an irregular slope. The specific steps are as follows: S1, Trench finishing

[0031] Small excavators were used to excavate the trenches, while manual cleaning of loose soil and debris was carried out. The bottom of the trenches and the banks on both sides were repaired to ensure that there were no obvious protrusions or depressions on the surface and that the slope error was controlled within ±5cm. S2, Installation

[0032] The two sets of devices from Example 1 are spliced ​​together and laid flat in the trench so that the thickened canvas bottom fabric (12) is completely attached to the bottom of the trench. The position of the device is adjusted so that it covers the entire length of the trench. The splice is sealed with canvas tape to prevent the slurry from leaking out. S3, Slurry Injection

[0033] Quick-setting cement grout is injected into the cavity structure 13 through the grouting hole 15. The grouting pressure is controlled at 0.2MPa. During the grouting process, the surface of the device is manually pressed to ensure that the grout fills the cavity evenly. The grouting volume of a single device is 0.8m³, which is 40% less than that of the traditional cast-in-place process. S4. Surface leveling

[0034] After the grout is injected, tighten the grouting hole cap 18, and manually use a scraper to level the surface of the device so that the device fits tightly with the groove contour and the surface flatness error is ≤3cm. S5, Device Fixing

[0035] At the fixed hole 14, a percussion drill is used to drill a hole in the original geological structure 5 of the embankment. The hole diameter is adapted to the expansion bolt sleeve 21. The anchor expansion bolt 2 is inserted and tightened. A total of 32 expansion bolts are arranged to ensure that the device is firmly fixed. S6. Backfilling and Greening

[0036] Backfill the area around the expansion joint with planting soil, and use a small rammer to compact it in layers with a layer thickness of 20cm and a compaction degree of ≥90%. After backfilling, plant water-tolerant green plants such as bermudagrass and calamus at a planting density of 20 plants / ㎡. S7, Maintenance Acceptance

[0037] After 7 days of natural curing, the structural strength and surface flatness of the ditch were inspected. The test results showed that the compressive strength of the ditch was ≥20MPa and the flatness met the design requirements. The ditch was then accepted and put into use.

[0038] Example 3: The difference between this embodiment and Embodiment 2 is that it is applied to municipal landscape drainage ditches. The ditch specifications are: bottom width 1.5m, opening width 2.5m, depth 1.2m, and the ditch has an arc-shaped slope. During the construction process, the shape of the device can be adjusted according to the curvature of the arc-shaped ditch when it is laid, without the need for additional processing. The grouting volume is 0.5m³ / set of device, and it is inspected after 5 days of curing. The overall construction cycle is shortened by 70% compared with the traditional process, and the ecological landscape effect is good after the green plants are planted on the banks of the landscape ditch.

[0039] In summary, a water-permeable and material-saving rapid construction structure for ditches comprises a thickened canvas outer layer, a thickened canvas inner layer, and rubber support columns. These three layers together form a honeycomb-like cavity structure, into which cement grout can be injected. The thickened canvas outer layer is water-permeable, accelerating grout solidification, and is lightweight and easy to lay. The cavity structure is material-saving, reducing grout usage while maintaining structural strength. The device is equipped with grouting holes and fixing holes for grout injection and device fixation, respectively. The fixing holes are equipped with anchor bolts to ensure a secure connection between the device and the embankment. The construction method includes seven steps: trench preparation, device laying, grout injection, surface leveling, device fixing, backfilling and greening, and maintenance and acceptance. The entire process requires no large hoisting equipment, is simple to operate, and is suitable for ditches of various shapes.

[0040] Industrial applicability: This invention can be widely applied to the construction of various ditch projects, such as farmland irrigation ditches, municipal drainage ditches, and water conservancy flood control ditches. The device requires no large equipment, can be operated manually, has high construction efficiency, low cost, significant material-saving effect, and is adaptable to ditches of different shapes. It also possesses ecological advantages and has good industrial promotion value and economic benefits.

[0041] 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, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
