Description

Technical Field

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

[0002] In recent years, prefabricated buildings and industrial modernization have developed rapidly in my country. The "Guiding Opinions on Vigorously Developing Prefabricated Buildings" further clarified that prefabricated building technology should be actively promoted in the future, and strive to make the proportion of prefabricated buildings in new buildings reach 30% in about 10 years. The advantages of prefabricated buildings are fast construction speed, less restrictions on climatic conditions, labor saving and improved building quality.

[0003] The rapid development of modern breeding industry has made modern heat-insulating and energy-saving pig houses replace traditional semi-open pig houses. In heat-insulating and energy-saving pig house buildings, it is necessary to set up manure trenches under the indoor floor; slatted boards are set up above the manure trenches, and the manure and flushing sewage produced by the pigs are collected into the manure trenches through the strip holes of the slatted boards.

[0004] There are many shortcomings in the traditional cast-in-place concrete manure ditch construction:

[0005] 1. Since the formwork and steel bars are manually set up on site, the construction speed is slow due to the significant impact of weather conditions;

[0006] 2. The construction quality is unstable and the precision control is difficult, which makes the inner size of the manure ditch inconsistent and the surface uneven, which is not conducive to the mechanized cleaning of manure;

[0007] 3. Manure ditches are prone to sedimentation and cracks, causing manure to leak into the underground soil, seriously polluting groundwater;

[0008] 4. Since the longitudinal dimension of the manure ditch is often large, the cast-in-place process makes it difficult to control the longitudinal slope of the manure ditch, which can easily cause difficulties in local removal of manure and affect the environment of the pig house. Summary of the invention

[0009] The purpose of the present invention is to provide a rectangular cross-section assembled concrete manure ditch and an installation method thereof, which can ensure the longitudinal slope of the manure ditch, improve the surface smoothness of the inner side of the manure ditch, adapt to the site transportation conditions of pig farm construction, and can significantly increase the construction speed and reduce the cost.

[0010] The present invention is achieved through the following technical solutions:

[0011] A rectangular cross-section assembled concrete manure ditch, which includes the following prefabricated components:

[0012] 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;

[0015] The inverted T-shaped prefabricated folded plate 4 is located between two adjacent prefabricated slope-adjusting beams 2, and the left and right sides of the inverted T-shaped prefabricated folded plate 4 are mounted on the L-shaped prefabricated folded plate 3;

[0016] The prefabricated leveling strip 5 is placed on the top of the L-shaped prefabricated folded plate 3 and the inverted T-shaped prefabricated folded plate 4;

[0017] Prefabricated slatted plates 6 are installed between two rows of prefabricated leveling strips 5;

[0018] 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, and the inner flange 1-2 is provided with a beam positioning groove 1-4 that cooperates with the prefabricated slope adjustment beam. Here, the bottom elevation of the prefabricated foundation 1 is gradually deepened 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 slope of the manure ditch.

[0019] 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;

[0020] The cross section of the L-shaped prefabricated folded plate 3 is L-shaped as a whole, including a vertical plate 3-1 and a horizontal plate 3-2 connected to the vertical plate 3-1, and a flange 3-3 is provided on the bottom surface of the horizontal plate 3-2 to cooperate with the plate positioning groove 2-1;

[0021] The cross section of the inverted T-shaped prefabricated folded plate 4 is in an inverted T shape as a whole, and includes a vertical plate 4-1 and a horizontal plate 4-2 connected to the bottom of the vertical plate 4-1, and both sides of the horizontal plate 4-2 are mounted on the horizontal plate 3-2;

[0022] The prefabricated leveling strips are placed on the top surfaces of the vertical plate 3-1 and the vertical plate 4-1;

[0023] The prefabricated slatted plate 6 is a square plate, and a plurality of parallel slits 6 - 1 are arranged on the square plate. The prefabricated slatted plate 6 is placed between the prefabricated leveling strips 5 on the top surfaces of the L-shaped prefabricated folded plate 3 and the inverted T-shaped prefabricated folded plate 4 .

[0024] A method for installing a rectangular cross-section assembled concrete manure ditch:

[0025] S1. Place the prefabricated foundation array 1 in the excavated foundation trench;

[0026] S2. Place the prefabricated slope adjustment beam 2 between adjacent prefabricated foundations 1, so that the end of the prefabricated slope adjustment beam 2 is embedded in the beam positioning groove 1-4 of the prefabricated foundation 1 (such as Fig.12 );

[0027] S3. The two L-shaped prefabricated folded plates 3 are placed between adjacent prefabricated slope beams 2, so that the flange 3-3 of the L-shaped prefabricated folded plate 3 is embedded in the plate positioning groove 2-1 of the prefabricated slope beam 2;

[0028] S4. The inverted T-shaped prefabricated folded plate 4 is placed between two adjacent prefabricated slope beams, so that the protruding portion 4-3 of the inverted T-shaped prefabricated folded plate 4 is erected on both sides of the L-shaped prefabricated folded plate 3 limiting grooves 3-4;

[0029] S5. The prefabricated leveling strips 5 are sequentially placed on the top surface of the vertical plate 3-1 and the vertical plate 4-1 (eg Fig.13 );

[0030] S6. The prefabricated slats 6 are sequentially placed between the prefabricated leveling strips 5 on the top surface of the L-shaped prefabricated folding plate 3 and the inverted T-shaped prefabricated folding plate 4;

[0031] S7. Fill the joints between the prefabricated components by grouting the base and / or the joints.

[0032] Compared with the previous technology, the beneficial effects of the present invention are:

[0033] 1. The main part of the assembled concrete manure ditch is built on a load-bearing structure composed of a prefabricated foundation 1 and a prefabricated slope adjustment beam 2. The elevation control requirements for the foundation trench excavation are low, and the elevation of the prefabricated foundation 1 can be easily adjusted to efficiently achieve accurate control of the longitudinal slope of the manure ditch. Compared with the conventional slope excavation method, the construction speed is fast, the accuracy is high, and the on-site construction cost is significantly reduced.

[0034] 2. The main part of the assembled concrete manure ditch is composed of two L-shaped prefabricated folded plates 3 and one inverted T-shaped 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.

[0035] 3. By combining the prefabricated leveling strip 5, the L-shaped prefabricated folded plate 3 and the inverted T-shaped prefabricated folded plate 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.

[0036] 4. By setting the flange 3-3 in the L-shaped prefabricated folded plate 3, the load borne by the cross plate of the L-shaped prefabricated folded plate 3 and the inverted T-shaped prefabricated folded plate 4 can be first transferred to the flange 3-3 and then to the prefabricated slope-adjusting beam 2. The above structure enables the bottom plate thickness of the assembled concrete manure ditch to be significantly reduced compared with the conventional solution. BRIEF DESCRIPTION OF THE DRAWINGS
