Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture building components, and in particular to a water-saving assembled concrete manure ditch and an installation method thereof. Background Art

[0002] The rapid development of the modern livestock industry, particularly the need to control African swine fever, has led to the replacement of traditional semi-open piggeries with insulated, energy-efficient piggeries. These require a manure ditch beneath the floor. Slatted panels are installed above the ditch, allowing pig feces and flushing wastewater to collect through the slatted holes.

[0003] The requirements for cleaning manure in pig houses should be based on the need for energy conservation and environmental protection, and the appropriate manure cleaning process should be selected. In recent years, the urine-foaming process has been favored by large and medium-sized pig farms in my country, while most small and medium-sized pig farms use dry manure cleaning and water flushing. The urine-foaming process is a relatively advanced manure treatment method recommended by pig farms in Europe and the United States. The urine-foaming process uses very little water. It only requires 20 to 30 cm of water to be placed at the bottom of the manure ditch for the first time. The urine produced by the pigs themselves is then used to soften the manure. This can save 70% of water in terms of water usage. It solves the problem of high water consumption of water flushing and traditional water-foaming manure, and also solves the problems of low labor efficiency and high labor intensity of dry manure cleaning.

[0004] When using the urine foam manure technology, the inverted trapezoidal cross-section manure ditch can significantly reduce the initial water consumption compared to the traditional rectangular cross-section. The traditional cast-in-place concrete manure ditch construction has many shortcomings:

[0005] 1. Due to the reliance on manual on-site formwork support and steel bar tying, construction is significantly affected by weather conditions, resulting in slow construction speed. 2. Excavation of the foundation trench for special-shaped manure trenches is difficult, requiring specialized finishing procedures and high construction costs.

[0006] 3. Unstable construction quality and difficult precision control result in inconsistent dimensions and uneven surfaces inside the manure ditch, which is not conducive to mechanized manure cleaning.

[0007] 4. Manure ditches are prone to settlement and cracks, causing manure to leak into the underground soil and seriously pollute groundwater; 5. Since the longitudinal dimensions of manure ditches are often large, the cast-in-place process makes it difficult to control the longitudinal slope of the manure ditch, which easily makes it difficult to locally remove manure and affects the environment of the pig house. Summary of the Invention

[0008] The purpose of the present invention is to provide a water-saving assembled concrete manure ditch and its installation method, which can ensure the longitudinal slope of the manure ditch, while ensuring the dimensional accuracy of the manure ditch with special cross-section, improving the surface smoothness of the inner side of the manure ditch, adapting to the site transportation conditions of pig farm construction, and significantly improving the construction speed and reducing the cost.

[0009] The present invention is achieved through the following technical solutions:

[0010] A water-saving assembled concrete manure ditch, which includes the following prefabricated components:

[0011] Prefabricated foundations 1 are provided in multiple pairs and are placed in the excavated foundation trench in an orderly manner in the front-to-back direction;

[0012] The prefabricated slope-adjusting beam 2 is erected between two pairs of prefabricated foundations 1;

[0016] Prefabricated slatted panels 6 are installed between two rows of prefabricated leveling strips 5;

[0017] The cross section of the prefabricated foundation 1 is in an inverted T-shape; it includes ribs 1-3 extending in the front-back direction, an outer flange 1-1 located outside the ribs 1-3, and an inner flange 1-2 located inside the ribs 1-3. The inner flange 1-2 is provided with a beam positioning groove 1-4 that cooperates with the prefabricated slope-adjusting beam.

[0018] The upper surface of the prefabricated slope-adjusting beam 2 is a slope that slopes downward from front to back, and the slope of the slope is consistent with the slope of the manure ditch in the front-to-back direction. Two plate positioning grooves 2-1 are provided on the top surface of the prefabricated slope-adjusting beam 2;

[0019] The first prefabricated folded plate 3 includes an outer oblique wing plate 3-1, a transverse bottom plate 3-2, and an inner oblique wing plate 3-3 connected in sequence. The profile of the transverse bottom plate 3-2 matches the profile of the plate positioning groove 2-1. A horizontal protrusion 3-4 is provided at the outer end of the outer oblique wing plate 3-1.

[0020] The second prefabricated folded plate 4 has an isosceles trapezoidal cross section, comprising a left oblique wing plate 4-1, a horizontal top plate 4-2, and a right oblique wing plate 4-3 connected in sequence, wherein the left oblique wing plate 4-1 and the right oblique wing plate 4-3 are respectively mounted on the top surfaces of the corresponding inner oblique wing plates 3-3;

[0021] The prefabricated leveling strip 5 is placed on the top surface of the horizontal protrusion 3-4 and the horizontal top plate 4-2;

[0022] The prefabricated slatted plate 6 is a square plate with a plurality of parallel slits 6 - 1 provided thereon. The prefabricated slatted plate 6 is placed between the prefabricated leveling strips 5 on the top surfaces of the first prefabricated folded plate 3 and the second prefabricated folded plate 4 .

[0023] A method for installing a water-saving assembled concrete manure ditch:

[0024] S1. Place the prefabricated foundation array 1 in the excavated foundation trench;

[0025] S2. The prefabricated slope beam 2 is placed between adjacent prefabricated foundations 1, so that the end of the prefabricated slope beam 2 is embedded in the beam positioning groove 1-4 of the prefabricated foundation 1;

[0026] S3. The two first prefabricated folding plates 3 are placed between adjacent prefabricated slope beams 2, so that the first prefabricated folding plate 3 of the transverse bottom plate 3-2 is embedded in the prefabricated slope beam 2 plate positioning groove 2-1;

[0027] S4. The second prefabricated folded plate 4 is placed between the adjacent prefabricated slope beams 2, so that the left oblique wing plate 4-1 and the right oblique wing plate 4-3 of the second prefabricated folded plate 4 are respectively erected on both sides of the first prefabricated folded plate 3 inner oblique wing plate 3-3 top surface;

[0028] S5. The prefabricated leveling strips 5 are sequentially placed on the top surface of the horizontal protrusions 3-4 and the horizontal top plate 4-2;

[0029] S6. The prefabricated slats 6 are sequentially placed between the prefabricated leveling strips 5 on the top surface of the first prefabricated folding plate 3 and the second prefabricated folding plate 4;

[0030] S7. Fill the joints between the prefabricated components by grouting and / or grouting between the joints.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The main body of this prefabricated concrete manure trench rests on a load-bearing structure consisting of a precast foundation 1 and precast slope-adjusting beams 2. This reduces the need for height control during excavation. The height of the precast foundation 1 can be easily adjusted to precisely control the longitudinal slope of the trench. Compared to conventional slope excavation methods, this method offers faster construction speed and higher precision, significantly reducing on-site construction costs.

[0033] 2. The main part of the assembled concrete manure ditch is composed of two first prefabricated folded plates 3 and one second prefabricated folded plate 4, which can simultaneously meet the size requirements of the manure ditch for pig farm breeding technology and the size restrictions of prefabricated components for transportation.

[0034] 3. By combining the prefabricated leveling strip 5 and the first and second prefabricated folded plates 3 and 4, the top surface of the assembled manure ditch wall can be made level, while the types of prefabricated components are significantly reduced, greatly reducing the prefabrication production cost.

[0035] 4. By placing the first and second prefabricated folded plates 3 and 4 upright, the load borne by the trapezoidal second prefabricated folded plate 4 is transferred as an axial force first to the inner inclined wing plate 3-3 and then to the prefabricated slope-adjusting beam 2, fully utilizing the spatial effect of the arched structure. This construction significantly reduces the thickness of the sidewalls and floor of the prefabricated concrete manure ditch compared to conventional solutions.

[0036] 5. The combination of the first prefabricated folded plate 3 and the second prefabricated folded plate 4 can make the manure ditch as a whole take on an inverted trapezoidal shape, thereby reducing the initial water consumption required for the urine and manure process and achieving the purpose of water saving.

[0060] The cross-section of the prefabricated foundation 1 is in an inverted T-shape; it includes ribs 1-3 extending in the front-to-back direction, an outer flange 1-1 located on the outside of the ribs 1-3, and an inner flange 1-2 located on the inside of the ribs 1-3. The inner flange 1-2 is provided with a beam positioning groove 1-4 that cooperates with the prefabricated slope-adjusting beam 2. Here, the bottom surface elevation of the prefabricated foundation 1 gradually deepens from front to back according to the front-to-back arrangement order of the prefabricated foundation 1, and the degree of deepening is determined according to the longitudinal slope of the manure ditch.
