Description

Technical Field

[0001] The utility model belongs to the technical field of farmland channel construction, and in particular relates to an assembled all-recycled aggregate waterproof concrete drainage channel. Background Art

[0002] Currently, in my country, the construction of new rural areas plays a crucial role in the modernization drive of society. The demolition of old buildings is an essential component of this process. During demolition operations, the primary method for disposing of construction waste, such as waste concrete, is still through stacking and landfilling. This large amount of waste concrete not only consumes valuable land resources but also raises a series of social issues, including environmental and ecological issues. Consequently, the continuous mining of large quantities of natural sand and gravel aggregates has led to the depletion of sand and gravel resources in some areas. This necessitates long-distance transportation of these materials, resulting in increasing costs and worsening environmental pollution. Recycling and reusing large quantities of waste concrete, or recycled concrete technology, is currently considered an effective solution to the waste concrete disposal problem. By crushing, cleaning, grading, and mixing waste concrete in a specific proportion, recycled aggregate can be obtained. This aggregate can then be used to prepare fully recycled aggregate waterproof concrete, resolving the waste concrete disposal issue while conserving sand and gravel resources. This achieves the goals of resource recycling and environmental protection while ensuring construction quality.

[0003] In the construction of new rural areas, modern agricultural production is inseparable from the scientific and effective construction of water conservancy facilities. Water is an essential element for crop growth. The vertical and horizontal ditches in farmland not only ensure the source of water for crop irrigation but also serve as drainage and flood control. Therefore, canals play a vital role in agricultural production. In current engineering practices, drainage canals typically use cast-in-place waterproof concrete grooved channel structures. However, these disadvantages require extensive on-site wet work, making construction quality difficult to guarantee. The cast waterproof concrete channels are prone to severe fractures, separation and deformation at the joints, and a long construction period.

[0004] Chinese patent publication number CN113699941A discloses an assembled recycled waterproof concrete drainage channel mechanism. The drainage channel mechanism has an open groove structure and comprises several plate layer units from top to bottom. The plate layer units are sequentially provided with a first plate layer and a second plate layer, with a first anti-seepage layer provided between the first and second plate layers. The first plate layer has multiple connecting grooves at both ends along the channel direction, and the second plate layer below the connecting grooves has multiple first bolt holes. However, this type of drainage channel has two plate layers, and during installation, the two plate layers must be connected together with bolts, which is cumbersome and has poor integrity. Furthermore, adjacent plate layer units are connected only by cast connecting grooves and post-cast strips, which can easily cause cracking and leakage between the two plate layers.

[0005] Therefore, an assembled fully recycled aggregate waterproof concrete drainage channel is proposed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

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

[0028] Reference Figures 1 to 7 As shown, this embodiment provides an assembled all-recycled aggregate waterproof concrete drainage channel, including: a plurality of prefabricated channel sections, adjacent prefabricated channel sections are connected end to end to form a drainage channel, and the drainage channel is an open groove structure; the prefabricated channel section includes a bottom plate 2, side plates 1 are fixedly connected on both sides of the bottom plate 2, connecting grooves 3 are provided at both ends of the bottom plate 2, the connecting grooves 3 are trapezoidal, and self-locking grooves 6 are provided at both ends of the side plates 1; the connecting grooves 3 of two adjacent prefabricated channel sections are correspondingly arranged, the groove eyes after splicing are regular hexagons and are poured with cement for connection, and the self-locking grooves 6 of the two adjacent prefabricated channel sections overlap each other.

[0029] The drainage channel is composed of several prefabricated channel sections spliced together, and the prefabricated channel sections are prefabricated with all-recycled aggregate waterproof concrete. On the one hand, it solves the problem of waste concrete disposal generated in the construction of new rural areas. On the other hand, it reduces the amount of wet work on site, solves the problem that the construction quality is difficult to ensure due to the large amount of wet work on site, and shortens the construction period. The drainage channel is spliced by large prefabricated channels, with fewer types of parts and simple assembly, which improves construction efficiency. During assembly, the two side plates 1 are interlocked with each other through self-locking grooves 6, which are difficult to move in the direction of the drainage channel, and can avoid the separation and breakage of the prefabricated channel section side plates 1. The two adjacent connecting grooves 3 are arranged corresponding to each other to form a regular hexagonal groove eye, and concrete is poured in the groove eye to connect. The regular hexagonal connecting column has good lateral force resistance. The multiple sides of the hexagonal column can better disperse and transmit horizontal force, improve the lateral force resistance of the connection, further avoid the fracture, separation, deformation, etc. of the prefabricated channel section connection of the drainage channel, and improve the quality of the drainage channel.

[0030] Furthermore, the concrete cast in the prefabricated channel sections and the connecting prefabricated channel sections all use fully recycled aggregate waterproof concrete with a strength grade of RC25 or below, which is prepared with recycled coarse aggregate. The fully recycled aggregate waterproof concrete is prepared with recycled aggregate, and the replacement rate of recycled coarse aggregate is taken as 100%, and the replacement rate of recycled sand is taken as 100%. The recycled coarse aggregate is made from the waste concrete after demolition operations in new rural construction, which is crushed, cleaned, graded and mixed in a certain proportion. This solves the problem of disposal of waste concrete, saves sand and gravel resources, and achieves the purpose of resource recycling and environmental protection while ensuring construction quality.

[0031] Furthermore, the thickness of the prefabricated channel section is 200mm-400mm, and the length of the prefabricated channel section along the channel direction is 2000-3000mm.

[0032] Furthermore, the self-locking groove 6 is a full-length groove, formed by splicing two isosceles trapezoidal concave-convex parts with a waist length of 150 mm, an upper base of 150 mm, and a lower base of 300 mm.

[0033] Furthermore, a 20mm post-casting strip is reserved at the edge of the prefabricated channel section, and the maximum width of the connecting groove 3 is 400mm. It is formed by isosceles trapezoidal grooves with a waist length of 150mm, an upper bottom edge of 150mm, and a lower bottom edge of 300mm, which are evenly arranged at a spacing of 450mm on the edges of the prefabricated channel sections on both sides.

[0034] According to a further optimized solution, a steel mesh 5 is arranged inside the bottom plate 2 and the side plate 1 , and the steel mesh 5 extends into the connecting groove 3 .

[0035] The steel mesh 5 extends in the connecting groove 3. The steel mesh 5 is cast in the connecting groove 3 during casting. The steel mesh 5 can enable the drainage channel to work better together when subjected to force, avoid large cracks at the connection, limit the distribution and width of the cracks, improve the tensile and shear resistance, and thus improve the integrity of the drainage channel.

[0036] According to a further optimized solution, the steel meshes 5 in the two opposite connecting grooves 3 are staggered.

[0037] The staggered steel mesh 5 can better disperse the stress and better adapt to complex stress conditions, so it has better shear and bending resistance and can better control the formation and development of cracks.

[0038] To further optimize the solution, the self-locking grooves 6 of two adjacent prefabricated channel sections are filled with cement mortar, and waterproof cloth 9 is laid at the joints.

[0039] The self-locking grooves 6 are filled with cement mortar, and waterproof fabric 9 is laid at the joints, so that the two can be connected tightly to avoid water leakage and increase the connection strength between adjacent prefabricated channel sections.

[0040] According to a further optimization scheme, an outer extension section 4 is fixedly connected to one end of the side panel 1 away from the bottom panel 2. The outer extension section 4 extends horizontally outwards. A steel mesh 5 passes through the outer extension section 4 and extends horizontally outwards. The section of the steel mesh 5 extending outwards is treated with rust prevention.

[0041] The outer extension section 4 is overlapped on the road surface outside the drainage channel, and the extension length is preferably 350 mm. This section of the steel mesh 5 is subjected to anti-rust treatment to avoid rust.

[0042] According to a further optimized solution, the outer extension section 4 is fixedly connected with a fixing component.

[0043] The fixing members are preferably nails, bolts, etc., which facilitate fixing the outer extension section 4 to the ground.

[0044] To further optimize the solution, a hydrological sensor is fixedly connected in the connecting groove 3.

[0045] Hydrological sensors are installed in drainage channels to facilitate real-time monitoring of water flow, water quality or other relevant parameters, so that the drainage channel structure not only has drainage functions, but also can provide data support to optimize water resource management and protect the farmland ecological environment.

[0046] To further optimize the solution, the hydrological sensor is fixed to the sensor base 7, and a connecting steel bar 8 is fixed to the bottom of the sensor base 7. The sensor base 7 is a regular hexagon, and the size of the sensor base 7 is larger than the size of the groove after the two adjacent connecting grooves 3 are spliced together. The connecting steel bar 8 is inserted into the connecting groove 3 and is cast connected to the connecting groove 3.

[0047] The hydrological sensor is fixedly installed on the sensor base 7. The size of the sensor base 7 is larger than the notch of the connecting groove 3, so that the sensor base 7 can be overlapped above the connecting groove 3. The connecting steel bar 8 is inserted into the connecting groove 3 and cast together with the connecting groove 3 to fix the sensor base 7.
