Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower engineering technology, specifically relating to a site leveling layout structure for a hydropower resettlement site in a mountainous area. Background Technology

[0002] Hydropower projects are often located in mountainous areas, where terrain constraints limit the availability of flat land. Traditional approaches include either scattering projects in clusters based on natural topography, leading to increased transportation costs and forced adjustments to social structures, or large-scale slope cutting to create platforms, generating significant amounts of rock and waste, and posing high risks to slope safety and environmental disturbance. Both approaches suffer from high investment costs, substantial environmental disturbance, and limited land availability, consequently impacting the livelihoods and relocation intentions of displaced residents. Therefore, a new site-leveling layout structure that adapts to mountainous terrain, controls differential settlement, is safe, reliable, economical, and environmentally friendly is urgently needed.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0004] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a site leveling layout structure for resettlement sites for hydropower migrants in mountainous areas. This site leveling layout structure for resettlement sites for hydropower migrants in mountainous areas actively adapts to deformation through structural hinges, making the structure safer and the functional zoning more reasonable.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A site leveling layout structure for a resettlement site for hydropower migrants in mountainous areas includes an excavation platform and a backfill platform. The excavation platform and the backfill platform are connected by a hinged transition device. The hinged transition device is a hinged slab transition strip, which is composed of a backfill platform slab and an excavation platform slab. The backfill platform slab and the excavation platform slab are hinged by a pin to achieve relative rotation, thereby converting the differential settlement between the excavation platform and the backfill platform into rotational displacement. The filling platform is a reinforced soil structure with geogrids inside, and it is anchored by anchor bolts and anchor seats.

[0006] Furthermore, the high end of the articulated transition strip overlaps with the load-bearing bracket set at the edge of the excavation platform.

[0007] Furthermore, the lower end of the hinged transition strip overlaps with the end bolster beam located inside the filling platform.

[0008] Furthermore, the end bolster beam is a support component adapted to the settlement of the filling platform, used to bear the load of the lower side of the hinged slab transition zone.

[0009] Furthermore, the geogrid set inside the filling platform is at least one layer.

[0010] Furthermore, anchor bolts are provided on both the filling platform slab and the excavation platform slab, which are used to fix the filling platform slab and the excavation platform slab to the corresponding underlying layer.

[0011] Furthermore, both the filling platform slab and the excavation platform slab are precast reinforced concrete components.

[0012] Furthermore, the precast reinforced concrete components of the filling platform slab and the excavation platform slab are installed on-site by hoisting.

[0013] Furthermore, the filling platform is also equipped with pre-embedded steel bars, which work together with anchor rods and anchor seats to anchor the filling body.

[0014] Furthermore, the articulated transition strip is used to achieve a smooth connection between the excavation platform and the filling platform, in order to ensure the structural continuity of the connection between the two platforms in conjunction with the differential settlement conversion function. This utility model provides a site leveling layout structure for a resettlement site for hydropower migrants in mountainous areas, including an excavation platform and a backfill platform. The two platforms are connected by a hinged transition device, which can convert the differential settlement between the two platforms into rotational displacement. The transition device is a transition strip composed of two plates hinged together by a pin, with its two ends overlapping the excavation platform and the backfill platform respectively. The backfill platform is a reinforced soil structure. This utility model actively adapts to settlement through a hinged connection, solving the cracking risk of rigid connections, and has multiple advantages such as geological safety, convenient construction, and social benefits.

[0017] The technical solution of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical expressions of the components and steps described in these embodiments should not be construed as limiting the scope of this utility model.

[0019] The following description of exemplary embodiments is merely illustrative and is not intended to limit the present invention or its application or use in any way. Techniques, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but where applicable, such techniques, methods, and apparatus should be considered part of this specification.

[0020] Example 1 This embodiment provides a site leveling layout structure for a hydropower resettlement site in a mountainous area, including an excavation platform A and a backfill platform 1. The excavation platform A and the backfill platform 1 are connected by a hinged transition device, which is a hinged transition strip 2. The hinged transition strip 2 is composed of a backfill platform backfill 201 and an excavation platform backfill 202. The backfill platform backfill 201 and the excavation platform backfill 202 are hinged by a pin 203 to achieve relative rotation, thereby converting the differential settlement between the excavation platform A and the backfill platform 1 into rotational displacement.

[0021] Among them, the excavation platform A is used to arrange residential buildings and other buildings that are sensitive to settlement, while the filling platform 1 can be used as a community square, sports field or green park and other public activity areas that are not sensitive to settlement. The articulated transition strip 2 can not only realize the smooth connection between the excavation platform A and the filling platform 1, but also cooperate with the differential settlement conversion function to ensure the structural continuity of the connection part of the two platforms and avoid stress concentration damage at the connection part due to differential settlement.

[0022] The fill platform 1 is constructed using reinforced soil technology, and its interior is equipped with geogrid 5. During the layered filling and compaction process, geogrid 5 is laid simultaneously, and at least one layer of geogrid 5 is installed to improve the integrity and tensile strength of the fill. At the same time, the fill platform 1 is also equipped with embedded steel bars 6, which work together with anchor rods 8 and anchor seats 7 to anchor the fill body. Anchor rods 8 are embedded in the lower stabilizing structure, anchor seats 7 are tightly integrated with the fill body, and embedded steel bars 6 enhance the internal connection of the fill body. Through the synergistic effect of the three, the long-term stability of the fill platform 1 is ensured.

[0023] See Figure 1-2As shown, the fill platform slab 201 and excavation platform slab 202 of the hinged slab transition zone 2 are both prefabricated reinforced concrete components. During construction, they are installed using on-site hoisting. Compared to on-site casting, this method has a shorter construction period, more precise quality control, and less environmental impact. During installation, the higher end of the hinged slab transition zone 2 overlaps with the load-bearing corbel 3 located at the edge of the excavation platform A, while the lower end overlaps with the end support beam 4 located inside the fill platform 1. The end support beam 4 is a supporting component adapted to the settlement of the fill platform 1, stably bearing the load of the lower end of the hinged slab transition zone 2 and preventing the slab from slipping during settlement.

[0024] The fill platform slab 201 and the excavation platform slab 202 are hinged together by a pin 203, thereby enabling relative rotation of the two slabs and converting the differential settlement between the excavation platform A and the fill platform 1 into rotational displacement. At the same time, both the fill platform slab 201 and the excavation platform slab 202 are equipped with anchor bolts 204, which are installed at the contact points between the slabs and the corresponding underlying layers. This allows the two slabs to be fixed to their respective underlying layers, preventing the slabs from sliding.

[0025] The method of achieving a rotatable connection between the filling platform plate 201 and the excavation platform plate 202 is not limited to the aforementioned pin shaft 203 structure. Other hinge mechanisms that can achieve rotational function, such as spherical hinge supports and high-strength flexible material connections, are also included within the protection concept of this utility model.

[0026] In summary, this utility model optimizes functionality by placing residential buildings on a stable excavation platform and public facilities on a fill platform. By combining excavation and filling with reinforcement of the fill, the usable land area is effectively increased. The combined excavation and filling significantly reduces deep excavation of the mountainside, rationally utilizes waste material, and greatly minimizes soil and water disturbance. The hinged slabs, made of prefabricated components, actively convert the settlement of the fill platform into rotational displacement, avoiding the risk of stress concentration failure at the connection points due to differential settlement, and facilitating later maintenance and repair. It not only solves engineering challenges but also provides valuable spaces for communication and recreation for the immigrant community by constructing a spacious and flat public activity space on the fill platform, contributing to the reconstruction of immigrant community culture and the integration of neighborhood relations, thus demonstrating significant social benefits. The above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
