Description

Technical Field

[0001] This utility model relates to the field of construction equipment for aquaculture facilities, and in particular to a support structure for the foundation pit of aquaculture farm. Background Technology

[0002] Sunken aquaculture farms, as important facilities in modern intensive farming, are characterized by creating underground or semi-underground farming spaces through deep excavation pits. During construction, the pit depth must extend several meters below ground level, and a reinforced concrete support structure is used to protect it against lateral soil pressure and prevent collapse. Currently, the mainstream support method employs on-site formwork and monolithic cast-in-place technology, forming a rigid support system through continuous walls or sheet pile structures.

[0003] While this technical approach ensures the structural integrity of the foundation pit during construction and use, the fixed spatial layout formed by the finished support structure and the pit makes it difficult to dynamically adjust its geometry and functional zoning according to the needs of animal husbandry, and it also presents a mismatch with the animal husbandry process. Furthermore, the traditional cast-in-place support structure results in a single spatial form for the pit, failing to physically separate the livestock activity layer from the excrement treatment layer. Manure accumulates directly at the bottom of the pit, highly overlapping with the animal activity area, which not only exacerbates the accumulation of harmful gases and the growth of pathogens but also leads to inefficient pit bottom cleaning. Leachate generated during the animal husbandry process easily forms stubborn stains on the pit walls, and the fixed support walls hinder the installation and maintenance of automated manure removal equipment, further increasing the difficulty of sanitation management and directly affecting the biosecurity level of the animal husbandry environment. This structural defect has become a significant technical bottleneck restricting the sustainable development of sunken animal husbandry farms.

[0004] Therefore, this utility model proposes a support structure for the foundation pit of a livestock farm to solve the problem that the above-mentioned sunken livestock farm has a single spatial form of the breeding pit, which cannot achieve physical separation between the livestock activity layer and the excrement treatment layer, resulting in difficulty in hygiene management and poor biosecurity level of the breeding environment.

[0040] The following is combined Figures 1 to 6 This invention describes the support structure for the foundation pit of a livestock farm.

[0041] A prefabricated foundation pit support structure for a livestock farm is provided for supporting the foundation pit of a sunken livestock farm. It includes side wall support components 1, support blocks 2, corner connectors 3, and partition plates 4, wherein:

[0042] The side wall support 1 is an L-shaped support plate, and the horizontal bottom plate of the side wall support 1 is rigidly connected to the concrete cushion layer 9 poured at the bottom of the foundation pit to form the bottom support structure of the foundation pit. The vertical plate of the side wall support 1 matches the side wall of the foundation pit and is used to support the side wall of the foundation pit.

[0043] The support block 2 is installed on the upper side of the horizontal bottom plate of the side wall support 1 and is in close contact with the vertical plate, forming a triangular reinforcement system of the bottom plate-vertical plate connection node. It is used to strengthen the strength between the horizontal bottom plate and the vertical plate of the side wall support 1, and at the same time, it plays a role in fixing the position of the side wall support 1 to prevent the side wall support 1 from overturning under the pressure of the pit side wall.

[0044] The corner connector 3 is installed at the corner of the foundation pit and is used in conjunction with the side wall support 1 to complete the stress transfer and shape transition at the corner during the foundation pit support process.

[0045] The partition plate 4 is a grid plate, which is installed on the side wall support 1 near the inside of the pit by the support block 2, and is used in conjunction with the support 5 pre-embedded on the cushion layer 9 to form a livestock and poultry activity area on the upper side of the partition plate 4 and an excrement treatment area on the lower side.

[0046] In the above description, the combined use of side wall support component 1, corner connector 3 and concrete cushion layer 9 forms a foundation pit support structure to support the foundation pit of the sunken aquaculture farm, ensuring the safety of the foundation pit; the setting of support block 2 and partition plate 4 realizes the physical isolation between the aquaculture area and the sewage area, so that the foundation pit support system can simultaneously bear the dual role of mechanical support and functional zoning, which effectively improves the construction efficiency compared with the traditional cast-in-place structure.

[0047] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the left and right ends of the vertical plate of the side wall support 1 are respectively provided with a first dovetail groove 11 and a first dovetail locking block 12. The first dovetail groove 11 is used in conjunction with the first dovetail locking block 12 of the adjacent side wall support 1, and the first dovetail locking block 12 is used in conjunction with the first dovetail groove 11 of the adjacent side wall support 1.

[0048] In the above description, by setting the first dovetail groove 11 and the first dovetail locking block 12, it is possible to achieve a quick and stable plug-in connection between adjacent side wall support members 1 during use, and at the same time, it can effectively ensure the stability of the obtained support structure.

[0049] Specifically, such as Figure 1 and Figure 2 As shown, the vertical plate of the side wall support 1 is also provided with a plurality of first anchoring holes 13. The first anchoring holes 13 are used in conjunction with the first positioning anchor rod 6. In use, they are used to install and fix the first positioning anchor rod 6 so that its rear end is anchored into the side wall of the pit, thereby enhancing the support stability of the side wall support 1 and preventing the side wall support 1 from overturning when subjected to the squeezing force of the pit side wall.

[0050] Specifically, such as Figure 2 As shown, the first positioning anchor 6 is a self-drilling anchor, which is convenient to install the first positioning anchor 6 inside the pit sidewall by rotating it during use, or it can be fixed inside the pit sidewall by grouting.

[0051] In a preferred embodiment, such as Figure 1 and Figure 3As shown, the support block 2 has a wedge-shaped structure. The bottom right-angle side of the support block 2 is connected to the side wall support 1 and is in close contact with the vertical and horizontal plates of the side wall support 1, forming a triangular reinforcement system of the bottom plate-plate connection node, which is used to strengthen the strength between the horizontal bottom plate and the vertical plate of the side wall support 1. The other side of the support block 2 away from the bottom right-angle side is a slope, which facilitates the introduction of excrement into the pad layer 9 during use. An installation platform is provided on the top of the support block 2 for installing the partition plate 4. The installation platform is also provided with an installation hole 21 for use with a connecting bolt 22, which is used to install the partition plate 4 on the upper side of the support block 2 during use.

[0052] In the above description, the support block 2 can strengthen the side wall support 1 and facilitate the installation of the partition plate 4.

[0053] Specifically, such as Figure 1 and 3 As shown, a second positioning anchor rod 7 is also pre-embedded at the bottom of the support block 2. The second positioning anchor rod 7 is also used in conjunction with the through hole 14 set on the horizontal bottom plate of the side wall support 1. It is used to stabilize the position of the support block 2 by passing the second positioning anchor rod 7 through the through hole 14 and fixing the second positioning anchor rod 7 to the bottom of the pit by grouting. At the same time, it can also play a role in stabilizing and fixing the side wall support 1.

[0054] In a preferred embodiment, such as Figure 1 and Figure 4 As shown, the corner connector 3 is a rigid connector installed at the corner of the foundation pit, and a second dovetail locking block 31 and a second dovetail sliding groove 32 are respectively provided on the two connecting side walls of the corner connector 3. The second dovetail locking block 31 is used in conjunction with the first dovetail sliding groove 11, and the second dovetail sliding groove 32 is used in conjunction with the first dovetail locking block 12.

[0055] In the above description, during installation, the first dovetail groove 11 of the adjacent side wall support 1 is inserted into the second dovetail locking block 31, and the first dovetail locking block 12 of the other adjacent side wall support 1 is inserted into the second dovetail groove 32, so as to realize the connection between the corner connector 3 and the two adjacent side wall support 1, and complete the stress transfer and shape transition at the corner position during the foundation pit support process.

[0056] In a preferred embodiment, such as Figure 1 and Figure 5As shown, the partition plate 4 is provided with several discharge ports 41, which are used to guide livestock and poultry manure into the upper side of the bedding layer 9 during use, so as to prevent the livestock and poultry manure from accumulating on the surface of the partition plate 4. It also facilitates the washing of the partition plate 4 during use, ensuring the cleanliness of the partition plate 4 during use. In addition, there are connecting holes at the four corners of the partition plate 4 to cooperate with the support members 5, which are used to support the partition plate 4 through the support members 5 to ensure the support force and stability of the partition plate 4 after installation.

[0057] In a preferred embodiment, such as Figure 1 and Figure 6 As shown, the support member 5 is disposed between the partition plate 4 and the pad layer 9 to support the partition plate 4 and ensure the stability and safety of the partition plate 4 during use. The support member 5 is provided with a connection hole at its upper end to connect with the partition plate 4 to ensure the integrity of the partition system.

[0058] Specifically, such as Figure 1 and 6 As shown, a third positioning anchor rod 8 is also pre-embedded on the pad layer 9. The upper end of the third positioning anchor rod 8 is connected to the support member 5 to fix the support member 5. At the same time, the four corners of the support member 5 are set as rounded corners to form an arc transition, so as to avoid blocking the flow of the sealing edge during use, so as to ensure the thoroughness of the treatment of livestock and poultry manure in the excrement treatment area.

[0059] In a preferred embodiment, such as Figure 1 As shown, the cushion layer 9 is poured at an angle at the bottom of the foundation pit to facilitate the flow of livestock and poultry manure during use, and to make it easier to clean the cushion layer 9 later.

[0060] The usage process of the farm foundation pit support structure described in this utility model includes:

[0061] During construction: After the bearing layer at the bottom of the foundation pit is leveled and compacted, first, place the sidewall support component 1 on the sidewall of the foundation pit. Then, according to specific construction requirements, fix it to the sidewall of the foundation pit. Next, install adjacent sidewall support components 1 and corner connectors 3 in sequence to form the foundation pit sidewall support system (before pouring the cushion layer 9, the foundation pit sidewall support system is not closed, leaving space for pouring the cushion layer 9); then pour the cushion layer 9, ensuring that the upper surface of the cushion layer 9 is flush with the upper surface of the horizontal base plate of the sidewall support component 1. And the overall inclination of the cushion layer 9; after the cushion layer 9 has solidified, the support block 2 is installed. During the installation of the support block 2, the second positioning anchor 7 (the insertion hole of the second positioning anchor 7 is reserved in advance) is fixed by the grouting method; finally, the partition plate 4 is installed, and the number of support parts 5 is set as needed during the installation of the partition plate 4 to support the partition plate 4 (the third positioning anchor 8 has been pre-cast when the cushion layer 9 is poured), forming a foundation pit support system that has both separation and support functions.

[0062] In practical use: Livestock and poultry are raised in the activity area on the upper side of the partition plate 4. During the raising process, the manure excreted by the livestock and poultry falls through the feed inlet 41 to the upper side of the bedding layer 9, effectively preventing the accumulation of manure on the surface of the partition plate 4. The manure falls to the bedding layer 9 and slides from the high elevation to the low elevation. At the same time, the surfaces of the partition plate 4 and the bedding layer 9 are cleaned regularly by flushing with water, which effectively ensures the hygiene of the sunken farm house during use.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
